Siamo tutti ciprioti!

La discussione in corso in queste ore a Cipro avrà conseguenze durevoli sul futuro dell'Europa e dell'euro. Secondo un editoriale del NYTimes di oggi 


A European plan could force Cyprus to tax bank depositors as a condition of a bailout in a way that would unfairly punish savers and could do lasting damage to confidence in banks in other euro-zone countries in financial crisis. The country’s leaders have a chance to change the agreement and should do so. (...)

Any tax on smaller accounts would set a terrible precedent. Savers in other troubled economies like Italy, Spain and Greece are now justifiably worried that their deposits may someday also be stripped of protection.

European leaders have said that taking money from Cypriot bank deposits is a singular event, but this assurance will ring hollow in light of their poor track record in dealing with the euro crisis. The plan has now given savers in Spain, Italy and other countries incentive to withdraw money from their national banks or move it out of the country if they have offshore accounts.

(Anche Wolfgang Munchau sul Financial Times ieri sosteneva la razionalità di un bank run nei PIIGS dopo quanto prospettato ai ciprioti...) Il NYTimes conclude senza mezzi termini

Cypriot officials created this catastrophe by relying on a lightly regulated banking industry to drive up its growth rate while encouraging foreigners to use the island as a tax haven. European officials also deserve blame for not requiring more capital in euro-zone banks and for not anticipating the consequences of lowering the value of Greek bonds. They should not add to those mistakes with a punitive package that is disastrously counterproductive.


Mi sembra condivisibile l'amarezza espressa oggi da Emma Bonino, ex commissario europeo

"Se andiamo avanti così ci sono tutti gli elementi antiEuro per determinare la prossima campagna elettorale". Emma Bonino, ex commissario europeo, parla così dell'impatto della vicenda di Cipro e in generale della gestione della crisi da parte di Bruxelles sulle politiche nazionali. "Si può e si potrà certamente continuare a dire che tutto questo è da irresponsabili, ma a me pare irresponsabile soprattutto il fatto che chi ne ha potere e poteri non si renda conto che persistere in questo modo testardo e a corto termine in questo tipo di politica e di assenza di democrazia, provoca uno sbriciolamento dell'attenzione al progetto europeo. E ogni giorno c'è un messaggio in questo senso". "Se il messaggio che arriva è questo - prosegue Bonino - è molto difficile chiedere ai cittadini o a un'europeista convinta come me di avere fiducia nell'Europa. Stanno provocando lo sbriciolamento del progetto e un grande sentimento contro questa Europa".

Addio Grecia? Aggiornamento al 9 marzo 2012.

Le ultime settimane sono state molto impegnative per me, e il blog ne ha risentito (ecco qui una delle cose che mi hanno occupato in questi giorni). Ma gli avvenimenti dell'ultima settimana, con l'entusiastica (....!?!) adesione dei creditori privati alla ristrutturazione del debito greco, impongono un commento, seppure breve. 
Da più parti si festeggia la buona riuscita dell'operazione, e il successo dell'LTRO (Long Term Refinancing Operation) da parte della Banca Centrale Europea, con la discesa dello spread BTP-Bund a poco più di 300 punti base. E' indubbio che inondare le banche di liquidità le ha messe in condizioni di riacquistare il debito italiano (e spagnolo) con benefici indiretti anche per le casse pubbliche. Ma come in molti osservano il debito dei PIIGS sia sempre più nelle mani delle banche dei rispettivi paesi e sempre meno in quelle delle banche straniere, rendendo di fatto molto più probabile l'uscita di paesi come la Grecia e del Portogallo dall'eurozona (potete esprimere la vostra opinione al riguardo nel sondaggio qui accanto): qui potete trovare un esempio delle analisi che girano soprattutto nelle newsletter economico-finanziare americane.

John Mauldin questa settimana afferma senza mezze misure che il contagio dalla Grecia agli altri PIIGS non è impossibile, anzi è sempre più probabile:


The sovereign debt crisis is not over. Not in Europe, not in Japan, and not in the US. It is in a lull period. And don't give me that old shibboleth, "The market is telling us that the crisis is over." The market knows a lot less than many pundits believe. What did the market know in mid-2007? Not very much, although the warning signs were clear, at least to some of us.


Sadly, the focus of the crisis will now move on to other countries in Europe. The economic arithmetic of the peripheral countries is not much better than that of Greece only a few years ago. The pronouncements and assurances from European leaders are about the same as they were a few years ago. Total European debt is at 443%, well above US debt of 350%. European banks are leveraged over 30 to 1, at least double that of US banks, which are nerve-wracking enough.

It is the time of the Endgame. There will be contagion.


 D'altronde, al di là della finanza, c'è una economia reale in condizioni disperate: la contrazione del GDP greco dal 2007 ad oggi è di quasi il 20% (-0.2% in 2008, -3.3% in 2009, -3.4% in 2010, -6.9% in 2011 e - 7.5% nel quarto trimestre del 2011), la disoccupazione in Spagna è oltre il 23% e quella giovanile viaggia intorno al 50%, in Italia negli ultimi 12 mesi è cresciuta dall'8 al 9.2% e in Portogallo dal 12.3 al 14.8%, in Irlanda pure si assesta al 14.8%. In Germania è invece scesa dal 6.3 al 5.8% e in Austria dal 4.5 al 4%. Ma l'unica ricetta che si propone per i PIIGS è l'austerità. E poi? Quando il prodotto interno lordo si sarà ancora abbassato e l'occupazione sarà ancora diminuita il debito sarà ancora più insostenibile e l'unica via d'uscita sarà l'abbandono dell'euro (lo è già da tempo per la Grecia e probabilmente anche per il Portogallo).

Gli asset seguiti settimanalmente da Alfa o Beta? non hanno messo a segno rialzi o ribassi consistenti, con variazioni comprese tra un +0.7% dell'indice SP500 in euro e il -0.9% dell'indice Eurostoxx.  
Le strategie  top2  e top3 questa settimana hanno segnato rispettivamente un +0,2% e +0.1%. Nel 2009 le stessa strategie avevano reso rispettivamente il 12.2% e il 2.4%, nel 2010 il 22.4% e il 18.2% mentre hanno chiuso negativamente il 2011 (-13,2% e -6,6%).

La strategia che investe negli asset con  tendenza di medio periodo positiva questa settimana  ha perso lo 0,1%. Positivo il 2009 +11,7%  e il 2010 con un rendimento pari al +12.1% leggermente negativo invece il 2011 con un -3,3%. Il rendimento annualizzato composto nel triennio è pari al  +7,1%, con un massimo drawdown del 9,2% e volatilità 10,3%.

I bilanci delle banche centrali a confronto

Vi segnalo un'interessante analisi comparativa dell'espansione dei bilanci delle banche centrali dalla Cina all'Europa: se si accetta come definizione di quantitative easing l'espansione del bilancio di una banca centrale è innegabile come persino la BCE non si sia fatta pregare negli ultimi mesi, con un aumento del 44% negli ultimi 6-7 mesi. Si scopre poi che i bilanci della banca centrale cinese e della BCE sono più ampi di quello della Fed (l'unica ad ammettere apertamente di ricorrere al QE) e che complessivamente The combined size of these eight central banks’ balance sheets (Cina, Europa, Giappone, USA, Germania, Francia, Svizzera e Regno Unito) has almost tripled in the last six years from $5.42 trillion to more than $15 trillion and is still on the rise!

Non ho nulla contro l'euro tranne il nome: dovrebbe chiamarsi marco tedesco

Il commento di GaveKal alla crisi europea pubblicato sul sito di John Mauldin questa settimana (link) analizza in modo abbastanza crudo (molti diranno semplicistico) la posizione della Germania e della Bundesbank sulla crisi dell'euro.

The Euro Debate Gets Philosophical

Anatole: Clausewitz, the Prussian military theorist, said in his reflections on the Napoleonic period that “war is the continuation of policy by other means”. If so, then it would seem that Germany is again at war with Europe; at least in the sense that German policy is trying to achieve in Europe the characteristic objectives of war: the redrawing of international boundaries and the subjugation of foreign people.
Likening German policy to warfare is a controversial argument, to put it mildly, so let me begin by briefly reviewing how events in Europe have unfolded in the past few months. Angela Merkel has consistently claimed that Germany would “do whatever it takes” to save the Euro. But what has she actually done? She consistently refused to take any of the actions that could actually work to save the Euro and has prevented European institutions from taking such actions, even when the German veto had no legal or moral justification.
As the Euro crisis has intensified and spread from clearly bankrupt countries such as Greece to Spain, Italy and now France, it has been universally acknowledged, at least outside Germany, that three actions are absolutely essential to resolve the Euro crisis and put the European economy back on its feet.
1. The first step would be to restore financial stability through massive purchases of government bonds by the European Central Bank. To succeed, these would have to be on a scale at least comparable to the “quantitative easing” undertaken in the past two years by the US Federal Reserve, the Bank of England, the Bank of Japan and the Swiss National Bank.
2. The second step would be to restore long-term solvency to all the nations of Europe by issuing new bonds, jointly guaranteed by the entire Euro-zone, which would replace part of the government debts run up in nations such as Greece and Portugal which are clearly insolvent.
3. The third step would be to improve and coordinate economic policies in all Euro-nations to restore economic growth, ensure that the restructured debts can be serviced and that another crisis does not occur.
By blocking the first two of these actions—large-scale ECB intervention and the issue of joint European bonds—Germany has guaranteed the failure of the third step, the restoration of economic growth and national credit. Why then has Merkel so blatantly contradicted her own stated policy of “doing whatever it takes” to save the Euro?
The initial judgment was that Merkel did not understand economics, or was too beholden to longstanding monetary traditions, or was simply incompetent. But while the crisis has intensified, Merkel has become ever more stubborn in her refusal to do what was obviously needed to save the Euro, as David Cameron discovered last week. So a different interpretation of her inconsistencies must now be considered. Is it possible that Germany, far from trying to save the Euro, actually wants to break it up? A clear historical precedent is the sabotage of the European exchange-rate mechanism (ERM) in 1992. And the institution that now seems to be working to destroy the Euro is the same one that organised the ERM breakup—the Bundesbank.
The Bundesbank, as an institution, has always opposed European monetary unification, except insofar as it meant the imposition of German economic philosophy on other countries. This attitude of monetary imperialism was summarised by a remark in nt Times obituary published for Richard Medley (the legendary hedge-fund consultant who was at the centre of the ERM breakup as George Soros’s political consultant). Helmut Schlesinger, the Bundesbank president in 1992, was asked why he disliked the precursor of the Euro, which was called the Ecu. He replied, “I have nothing against the Ecu apart from its name—I think it should be called the Deutschemark”.
Back in 1992, the Bundesbank encouraged Soros and other speculators to sell Sterling and the Italian Lira in order to break up the ERM. But the Bundesbank also discretely hinted that the French Franc should be supported because France was in a different category as a German ally from Italy, Britain and Spain. As Soros later said in an interview, also quoted in last week’s obituary for Medley: “I felt safe betting with the Bundesbank. The Bundesbank clearly wanted the Pound and Lira devalued, but it was prepared to defend the French Franc. I did better than some others by sticking to the Bundesbanks side.”
Today, the role of the Bundesbank in destabilising the European financial system is much more open than it was 19 years ago. Axel Weber, the former Bundesbank president, and Juergen Stark, the former vice-president, both voted against ECB support for Greece back in May 2010 and then publicly denounced these measures to the German media, in an almost unprecedented breach of central banking protocol. Last summer, when the ECB decided to extend its half-hearted support to Spain and Italy, Weber and Stark both resigned in protest—and launched openly political attacks on their own government’s European policies. A few weeks later a story emerged in The Financial Times reporting that Siemens had become nervous about the French banking system and withdrawn its cash balances from Societe Generale to deposit them “for safety” at the ECB. It is hard to imagine who could have leaked this story other than the Bundesbank?
Today, the Bundesbank is in the forefront of a campaign to persuade the German public and the German government that ECB bond purchases and quantitative easing are illegal under European law. In truth, the EU treaties specifically allow the ECB to buy bonds, as long as it does not do this directly from governments. And EU laws say nothing at all about the effects of quantitative easing—which is not surprising since QE is a complex issue of economic theory that could not possibly be subject to determination by the courts. What the Bundesbank believes, however, is that European law should have made bond purchases and expansionary monetary policy illegal—and if other European countries refused to write these laws into EU treaties they will just have to be imposed by Germany through financial main force.
In short, the Bundesbank policy on the Euro crisis is to present the other countries of Europe with a stark ultimatum: either they accept German economic directives, German monetary theories, German financial practices and even governments imposed by Germany, as part of a draconian new regime for national insolvency and administration. Or they must face financial chaos and expulsion from the Eurozone, under a new exclusion procedure now demanded for nations that refuse to submit to German rules. In short, Germany is trying to achieve through monetary diplomacy what were previously the objectives of warfare: redrawing the boundaries of Europe and imposing German ideas on those nations that remain within. That, surely, is a continuation of war by other means.
Charles: Dear Anatole, my first answer to the above is that there is nothing new here. I have argued incessantly in every single one of our debates since Axel Weber’s resignation that the Bundesbank was now in an open war with the concept of the Euro. I have also pointed out that, in my career, I have seldom made money when betting against the Bundesbank.
Now there are of course many reasons behind the hostility of the Bundesbank to the Euro. The first is obvious enough: the Euro was thrust on an unwilling Bundesbank by Mitterrand and Delors as a compromise to France accepting German re-unification. So the Euro’s very birth was an unhappy one to start with.
Beyond that, the hostility rests, I believe, on important philosophical differences. Indeed, Max Weber suggested two sets of ethical virtues that a proper political education should teach: the ethic of conviction (Gesinnungsethik) and the ethic of responsibility (Verantwortungsethik)According to the ethic of responsibility, an action is given meaning only as a cause of an effect; i.e., what matters is the consequences. According to the ethic of conviction, on the other hand, a free agent should be able to choose autonomously not only the means, but also the end; “this concept of personality finds its „essence in the constancy of its inner relation to certain ultimate „values and „meanings of life”. Weber recognized a gulf between his “Two Ethics,” one which is concerned with consequences and one which is duty– and rules-bound. His problem arises from the recognition that the kind of rationality applied in choosing a means cannot be used in choosing an end. Increasingly, the current debate on the Euro is nothing but a conflict between these two forms of ethics.
In one camp, are those who, like François and yourself, say that nothing is more important than preventing a collapse of the Euro. In the other camp, the Germans say that nothing is more important than upholding the international treaties, and maintaining the supremacy of the law over the pressure of short-term solutions.
Now because of its unfortunate history, this debate can get emotional very quickly in Germany. Indeed, more than any other people, the Germans have suffered from adopting the second view, with huge negative consequences for Europe and the world. As a nation, it is thus my impression that Germany has come to the conclusion that, at the end of the day, one should never tamper with the law, whatever short-term benefits such tampering might bring.
If we apply this distinction to what money is, those who believe that money is a tool which belongs to the political sphere and can be manipulated to meet political goals, justify their destruction of money by an ethic of responsibility (fighting unemployment, creating economic growth, etc). For what it is worth, let’s call them “Keynesians”. On the ethic of conviction, we have the Bundesbank and the German population (but not so much the German political system) who say that money is a common good which does not belong to the state, and that the economy has to adapt to this reality, and not the other way around. Let us call them the “Austrians”. As our readers know, Anatole, you are intellectually very much in the first camp, while I plant my flag in the second. With that in mind, the current debate on the Euro can be framed as such:
· On the one hand, there are those who believe that the end justifies the means. If saving the Euro requires the destruction of the notion of money as a common good, so be it. The fact that the Euro is slowly destroying Europe (as was entirely predictable—and predicted in our pages), thus leads our “Keynesians” to recommend measures and actions which have been specifically forbidden in the treaties, the German constitution, or the bylaws of the ECB.
· On the other hand, there are those who remember that Hitler said that treaties and constitutions were nothing but pieces of paper. For such Germans, it is simply inconceivable that the law could be made subservient to a political or economic goal. They believe that destroying the law is far more dangerous than destroying the Euro, and they say to the others that the solution is simple: they signed the Treaties, they now have to respect them.
I respect the German vision. The treaties creating the ECB and the Euro were built around the German notion of money and everybody knew it. So when Merkel says that the others have to become Germans, she is perfectly entitled to do so, since it was exactly what the treaties said (and why the British, Swedes and Swiss rightly refused to join). In my view, on this point, the Germans are right. Frankly, one does not sign a treaty with Germans in the hope that the Germans will be flexible. They never were, and given their own history, are now less so than ever.
I also have a lot of sympathy for the German view of questioning why we should sacrifice every rule, and treaty, to uphold a currency that is clearly not working for a number of countries? Must the survival of the Euro in Southern Europe really only occupy every waking hour, of every European policymaker (and investor)? Must it really take precedence over every other institutional framework? In short, is the Euro really the end-all, be-all of European civilization; the altar on which everything else can be sacrificed? Is this really as good as we get? Or are European policymakers only trying to save the Euro (and sacrificing the youth of a number of countries) to avoid having to admit that they made a colossal mistake?
Louis-Vincent: In all our previous debates, and in The Divergence in European Spreads—Why Now?, I argued that there were four possible resolutions to the European crisis:
1. The first was for troubled countries to leave and redenominate their debt in their local currencies, thereby avoiding a default but imposing massive foreign exchange losses on foreign bondholders.
2. The second was for Germany to leave—though this seemed highly unlikely as this would in essence bankrupt every German bank, insurance company and pension fund (whose liabilities would be redenominated in DM and whose assets would remain in Euros).
3. The third was for the weaker links to default and restructure their debt.
4. The fourth was for the ECB to become far more aggressive in its purchases of troubled-country bonds and swell its balance sheet.
Now up to just a few months ago, the Europtimists kept arguing that all these events were just not going to happen. Instead, the more likely scenario was one of deep structural reforms combined with some fiscal transfers and a little bit of help from the ECB. Such a combination, I was told in many meetings and even in some of our internal debates, would help to keep the Euro-show on the road.
Fast forward to today, and every Europtimist (see the latest The Economist) is now arguing that solution 4 has to be the answer. Obviously, this is also what Anatole is arguing for by equating the German resistance to such an outcome to an “act of war.” So already we have witnessed quite a paradigm shift. But is it now too late for this? In other words, have Europe’s debt crisis and deflationary-bust moved beyond the powers of an ECB’s magic wand? Not that I don’t believe in Santa Claus, or in the ability of central banks to cure every ill, but it seems to me that, should the ECB decide (a day late and a Euro short?) to now intervene in size to prevent the European bond markets from deteriorating further, it would face some very significant hurdles.
Above, Charles focuses on the philosophical hurdles to any mass intervention. And while I subscribe to Charles’ reading of the German institutional framework, my concerns are far less intellectual and far more practical. Basically, we have to remember that the average sovereign debt buyer is not a hazardous investor. The guy who buys a government bond is looking for a very specific outcome: he gives the government 100 only so he can get back 102.5 a year later. That’s all the typical sovereign debt investor is looking for. Nothing more, nothing less.
But now, the problem for all EMU debt is that the range of possible outcomes is growing daily: possible restructurings, possible changes in currencies, possible assumption of other people’s debt, possible mass monetization by the central bank etc. Given this wider range of possible outcomes, and the consequent surge of uncertainty, the natural buyer of EMU debt disappears. Again, the typical sovereign investor is not in the game of handicapping possible outcomes; he is in the game of getting capital back!
This is very problematic because once uncertainty creeps in, bonds will tend to gradually drift towards what I have come to call the bonds “no-man’s-land”. Basically, once sovereign bonds reach 90c to par, they tend to have a much higher volatility and much greater uncertainty. As a result, they are no longer attractive to the typical bond manager or asset allocator looking to buy bonds to diversify equity risk (think how Italian bond yields are now correlated to European equities. If you want to be bullish Italian bonds, you may now just as well spend a fifth of the money and buy European banks for the same portfolio impact…). And once a bond enters into no-man’s-land, it has to fall a lot before attracting the attention of distressed debt and vulture investors (usually yields of 15%+). So the first obvious problem is that more and more European debt markets are entering this “no man’s land” bereft of “normal” investors.
Of course, this invites the conclusion that the ECB should thus do everything in its power to bring the bonds out of this no-man’s land. But what are those magical powers the market keeps referring to? After all, the various European institutions (ECB, EFSF…) and the IMF have mopped up almost a third of the Greek debt and yet it is now trading at 25c on the Euro! Perhaps this goes back to the way a typical sovereign debt holder thinks? Indeed, let us imagine that, tomorrow, the ECB follows every editorialists’ advice and comes in to mop up a third of Spanish and Italian debt in a bid to get yields fixed at, say 5%. Will our Spanish and Italian bondholders a) jump at the chance to get out of their positions with a smaller loss than forecast? Or b) sit tight and allow themselves to be transformed into junior bond holders?
Indeed, the Greek precedent (where basically the ECB insisted on being made whole while the private sector shared in the losses of lending money to the spendthrift Greek government) means that the default assumption of sovereign debt holders should be that a mass intervention of the ECB into their markets will relegate them to the “junior ranks.” And needless to say, most institutions who invest in sovereign bonds are not looking to be junior bond holders. They are looking for absolute safety. So in a perverse way, massive purchases by the ECB may actually highlight that the asset one owns is anything but safe; implying that for an ECB intervention to work, the amounts would likely have to be staggering. This is why I tend to believe that even if the Bundesbank did agree to monetization (which as Charles highlights is hardly a foregone conclusion), the window for this to work may now have closed. Instead we should brace ourselves for either defaults, or countries leaving and re-denominating debt in local currencies.
Anatole: Charles, your Weberian response to my article on Germany's war against Europe is thought-provoking. But it leaves out two crucial points:
Firstly, It is not at all clear that asking the ECB to buy bonds in the secondary market conflicts with any law. This is Merkel's interpretation of the EU treaty. But all that the treaty actually says (Article 123) is that the ECB will not finance governments by providing “overdraft facilities” and buying their debt directly in the primary marketThe legislative history of this article is interesting. The Germans wanted a tougher prohibition about monetary financing written into the Maasrticht Treaty, but the other countries refused. The compromise was Article 123. Merkel is now trying to interpret this article as if it enshrined the laws that theywanted. It is therefore the Germans who are trying to twist the law in their favor, not the French, Italians, etc.
Secondly, laws need to be changed with the passage of time. That is what government, and especially democracy, is for. Therefore a dogma of upholding the law as it is, regardless of circumstances, and refusing to change it is not justifiable even for Weber's “ethic of conviction”. Your response to this objection would presumably be that some laws are so important that they should never be changed even by a democratic decision—for example, laws on human rights, racial equality and religious freedom, constitution arrangements and other fundamental laws (which is actually what Germany calls its constitution). I fully agree with this, although even constitutions always contain an amendment process—at least if they are properly drafted, which of course the treaty on European Union never was! Still, it is clear that your ethical argument (and Merkel's) only applies to tampering with fundamental laws, not the much larger number of everyday regulations that are needed for society to function, e.g.: driving speed limits, postal charges...
The question, therefore, is whether monetary laws should be treated as ethically fundamental in the same way as laws on free speech, political association, religious freedom, property rights, capital punishment, etc. I personally do not think so. To me economics is a pragmatic activity with no clear answers. The “right” of a central bank to operate independently of government is not, in my view, an ethical question, comparable to capital punishment or even the right of the citizens to adequate healthcare. This is, I think, the fundamental point on which you and I disagree.
Which leads to my third objection: even if we accept that the “right” of central bank independence is a fundamental right comparable to other constitutional requirements, Merkel is not upholding this right. In fact she is doing the opposite. She is issuing political instructions to the ECB on what it cannot do. If the Germans genuinely believed in the rule of law and in central bank independence, they would not try to prevent the ECB from doing whatever it thought was necessary and desirable. If the ECB board, as properly constituted under the EU Treaties, voted to buy the entire Italian, Spanish and French secondary bond market and to engage in QE to the tune of €10trn, then Germans would have to calmly accept this as a lawful consequence of the treaties their government had freely signed. In fact, therefore, Merkel is not exemplifying the respect for law and ethics of conviction as you describe. She is reinterpreting laws and tampering with treaties in whatever ways happen to suit her.
Charles: Anatole, since we are treading on philosophical grounds, could I say that we must both have studied casuistry in our youth for this is increasingly looking like a debate between a Jesuit and a rabbi.
On your first point, if a French commercial bank subscribes to a French bond and sells it in the following second to the ECB, what do you call this? Moreover, doesn’t the treaty specifically forbid joint responsibility of the debt and the mutualisation of said debt? What the ECB is doing in buying in the secondary markets in amounts higher than those needed for its open market operations is not compatible with these parts of the treaty (even if it is compatible with article 123), since Germany could be on the hook if a country failed (through the participation of the Bundesbank in the ECB). So it seems to me that Merkel is perfectly entitled to her legal views: the ECB’s recent actions are de jure and de facto against both the letter (no mutualisation of the debt) and the spirit (no financing of budget deficits by the central bank) of the treaty.
On your second point, I most definitely do believe that money is far too important to be left under the control of politicians (especially French ones!) and let me explain why. The purpose of economics is to understand why things have a value and why those values change over time. To do so requires a measurement in “money”. But no economist has ever been able to explain why money has any value since it has a marginal cost of production of zero. For me, money is a kind of social contract which binds a “demos” (Plato called it a “convention”) where citizens accept to use it in their transactions or for their savings. But this convention is a very fragile thing.
Renan used to say that a nation is defined by the willingness of its citizens to live together, and this willingness was what created a “demos.” There is no European demos, so there is no possibility of a European currency. To make it simple: to each demos its currency. There is no European Nation, there is a European Civilization, which is not at all the same thing (see Was the Demise of the Soviet Union a Negative Event?). Money thus does not belong to the government, but is a common good of the demos.
If I have learnt something after the debacle of the so-called “financial revolution of the last twenty years” it is that one should never put the monetary policy under the control of the politicians, and that money should never be “privatized,” or put under the control of the market, since it has a marginal cost of production of zero. The privatization of money which started under Clinton, and was continued under Bush and Greenspan, led to the current disaster. In my view, money is a common, (and more importantly—perhaps as I am getting older) trans-generational good that no generation should be able to manipulate for its benefit. The only role of the government should thus be to regulate the credit system without which an economy cannot work. The attempt to regulate this credit system internationally rather than at the national level is the root cause of the current problems, the governments having failed miserably in their regulatory role. Since they have failed, like any bad trader, they are now busy doubling and tripling down. This never works.
On your third point, I have read a thousand times that if the board of the ECB decides on monetization of the debt, the Germans should just accept that decision. Except of course that the board is bound by the bylaws or the treaties which specifically forbid such a decision. What Merkel is saying is thus very simple: if the board gives in to the French or the Italians because they have the majority, then this decision will not be legally binding for Germany. In other words, she is telling the board members to respect the treaties, which guarantee the ECB independence against French or Italian politicians looking for an easy exit, as they always do, or else…
This seems to me perfectly fair and leads me back to my original point, which our latest exchange of emails amply proves: you believe that the end justifies the means (ethic of responsibility). I (like the Germans) do not (ethic of conviction). To conclude on a historical note, I believe that Chamberlain practiced the ethic of responsibility and Churchill the ethic of conviction. And reviewing Chamberlain’s actions, Churchill said “they accepted dishonor to avoid war. They will have the war and will have lost their honor”. Looking at your proposed remedies, your solution is to destroy money to avoid ruin. We will have the ruin; it is too late and will lose our “money” anyway. Destroying money does not create wealth any more than deregulating it.
Anatole: As you have raised the issue of casuistry I must return the compliment and say that your casuistic education must have been even better than mine.
You are right that the ECB has been funding EU governments via the banking system, but the Germans never objected to this—and still do not—for the simple reason that this form of government funding is considered acceptable in Bundesbank theology. Why this is so has never been clear to me, but it must originate in some theorem of Austrian economics which I never studied. Last year, I had the chance to put this question to Axel Weber himself and he confirmed in the clearest terms that ECB lending to banks which then on-lend to governments is a perfectly acceptable way to conduct monetary policy.
Incidentally, some of the people I met in Frankfurt last week were as baffled as I was by the Buba doctrine that financing the Greek government directly is unacceptable, whereas funding insolvent Greek banks so that they can finance their government is perfectly OK. In any case, this issue of financing governments was thoroughly debated and negotiated in the Maasrticht Treaty talks. The result, as I said in my earlier email, was that the other countries refused to go as far as the Germans wanted in forbidding monetary financing under Article 123. Moreover, the German demand for a prohibition on mutualisaing debt, which you mention, was also rejected by the other countries at Maastricht. I know the Germans are always quoting the so-called "no bailout clause", but like the monetary financing clause this part of the treaty does not say what the Germans now claim. The no bailout clause (Article 125 of the new Lisbon Treaty) says this: "A Member State shall not be liable for or assume the commitments of central governments...or public undertakings of another Member State, without prejudice to mutual financial guarantees for the joint execution of a specific project."
This leaves plenty of scope for EU member governments to agree on mutual guarantees for institutions such as the EFSF and ESM to execute a specific project like the rescue of the Euro. Again, this is a case where the Germans, having failed to achieve their objectives in the original treaty negotiations, signed up anyway and are now trying to reinterpret the laws retrospectively to get what they want. Far from showing respect for Laws and Treaties, this is uncomfortably reminiscent of the German attitude to the Treaty of Versailles.
Now you may be right that money is a public good which should not be subject to political manipulation, but the precise mechanisms for issuing and managing money have always been subject to change—and rightly so, in my view. We both agree that returning to the gold or silver standard would not be a good idea even though money was “always” managed like that until the 1930s. Of course, others have different ideas about the gold standard and these are quite legitimate. And there are a multitude of different views about whether it is best to control money by using interest rates or inflation targets or monetary targets and which ones - eg monetary base, M1 or M3 or the exchange rate.
These different views about monetary management are not about moral or philosophical issues. They are empirical judgments about what works best in the real world. Thus the German idea that monetary financing of government deficits will always and everywhere generate inflation and destroy confidence in the public good money (which you seem to share) is not a moral principle. It is a particular view about how the economy works which can only be judged by whether it turns out empirically to be right or wrong.
As it happens, an important experiment is now being conducted in monetary financing all over the world. If the US, Britain, Japan and Switzerland, all of which are now engaged in monetary financing, suffer serious inflation and a loss of confidence in the value of money, then the Germans (and you) will be proved right. Thus far, however, most of the evidence points in the other direction. (By the way I am not claiming in the last sentence that monetary financing has been successful in managing the US, British, Japanese and Swiss economies—that is another issue—but merely that it has not undermined the public's desire to hold money, as the Germans and you seem to believe).
Finally, I have already responded to your point about what the laws actually say above. So let me comment on your claims about unprincipled pragmatism.
It seems to me that “The End justifies the Means” is actually a good description of your approach to this whole single currency disaster. For you, ‘the End’ is the breakup of the Euro and you are willing to endorse all kinds of dishonest and economically destructive behavior from Germany to achieve this end. I believe, on the contrary, that Merkel should be judged on the effects on the world of what she is doing as well as on her party’s motivations, which are politically self-serving and short-sighted. Like you, I would prefer to see the Euro break up, but I am not going to pretend that Merkel and Axel Weber are morally right, simply because their behavior happens to be advancing my side of the argument.
So in conclusion, I would return to a point that I have made before; namely that if Germany continues to want to play by its rules, rather than the rules of the community, then France should invite Germany to leave the Euro.
François: Anatole, even if your scenario of Germany leaving the Euro made economic sense for France (on which I am not convinced), I am sure that you have already noticed that French politicians are not that interested in economics. Instead, plans that are economically consistent but that threaten the French political influence in large parts of Europe remain a non-starter for our dear énarques. And you will never convince the French that they might eventually regain this influence thanks to the indirect, magical effects of a devalued currency. They won't believe in it (I don’t either, by the way), and even if they did believe in it, they would never have the guts to bet on it anyway. Maintaining the status quo remains the default option for any French politician.
In Capitalism 4.0, you wrote how many UK economists and politicians had been surprised by the good performance of the economy in the years after the Pound left the ERM. You explained that many in the UK initially feared that this "loss of monetary anchor" would lead Britain to nowhere. On the contrary, it provoked renewed internal confidence. Could this benefit happen to France and Italy? Implicitly, this is your bet, and I find it very interesting. But as you know the UK Pound did not stay in the ERM for long, while France and Italy have anchored their monetary destiny upon Germany for more than 30 years. It is in this respect very telling that Italy did not stay long outside the ERM after it was forced to leave in 1992 (it joined back in 1996). Similarly, France did not leave the ERM in 1983. For sure, these successive political choices might be seen as meaningful of countries that lack self-confidence, and these different episodes might well have represented lost opportunities to pursue more sensible economic policies. But for both historical and economic reasons, France and Italy have felt that they needed to keep up with Germany in order to participate to the elaboration of a soft-power of global dimension, which is what the European project is about. Whatever opinion we may have about how this project is being conducted, it is a very respectable project. And after so many years and so much capital invested in it, its possible dismantling would leave much deeper scars and provoke a much larger chaos than when the UK Pound left the ERM.
Anatole: François, you have hit the nail on the head. I agree with you completely that the French enarques would not want to break with Germany even if it could be demonstrated with 99% probability that such a policy would make France stronger and more prosperous. Such is the power of what I believe you call the “pensée unique”. But the problem is not a political one but is now an economic one. In other words, French politicians may decide to ignore economics but the rules of economics are not ignoring France and France may well not be able to cling to Germany much longer. This is especially true if the Germans now realise that France has become completely subservient and that, therefore, Germany no longer needs to compromise in any significant way to accommodate French demands. In short, France is currently living through yet another “Sedan”!
Louis: Speaking of Sedan, once it becomes apparent that the enarques are turning France into a German colony isn't it possible that the public will rebel? In other words, could we not see another “Paris Communes”? At the very least, we will likely see Marine Le Pen make new gains for the National Front in May, and likely make it to the second round. And who is to say that, as the French economic situation deteriorates further, she doesn’t face off against another fringe candidate, perhaps from the far left? Let us not forget that the combined far left (communists, various Trotskyites parties…) have typically polled a combined 15-25% in French elections. Fortunately, they were always scattered amongst many parties (in a scene reminiscent of “The Life of Brian” with the “Judean People’s Front,” the “Popular Front of Judea,” etc…). But now that they are gathered under the Melenchon roof...
Francois: Since 1983, French voters have indeed voted more and more against the traditional parties (2007 was an exception to this rule). It is however not that easy to assess why. Many countries with independent economic policies are seeing the rise of the extreme right or left, while in a suffering Euro country like Spain, the traditional parties continue to attract 95% of the votes. I would thus not be able to demonstrate that the rise of political tensions and dissatisfaction in France or Italy has been due to the anchoring of economic policy on Germany, contrary to what the you suggest.
Moreover, in France, the return of the German constraint upon economic policy is for now leading the country more towards introspection (the realization of the huge costs of our so-called social model) rather than towards resentment against Germany. In fact it is even possible that, contrary to what you suggest, the centrist parties attract more, rather than less, votes in the next elections as more and more people realize that the country needs to be more seriously managed. We will see.
Finally, what exactly are the real benefits of a rebuttal of the German constraints? I suspect that Anatole is too much influenced by the success of the devaluation of the Pound in 1992. But in Italy, which left the ERM at the same time, the following years were far less fun, as the chart below illustrates:
Indeed, the UK could enjoy the benefit of the 1992 devaluation because its economy had been re-vitalized by the reforms of the Thatcher era (meanwhile, today, after more than a decade of creeping Blair-Brown health and nanny-statism, it is a very different story!). Anyway, I do not think that anyone in France would suggest that if Germany left the Euro, or if France simply refused the German constraint, the French economic situation would improve. Our problems are of our own making and are not so much related to having the wrong currency, as to having a welfare, and regulatory, state on steroids.

L'oro come difesa dagli errori dei politici

Kyle Bass è il fondatore del fondo hedge Hayman Capital di Dallas, Texas. E' diventato celebre per le sue scommesse vincenti durante la crisi finanziaria del 2008, documentate nell'ultimo libro di Michael Lewis’s  Boomerang: The Meltdown Tour. Bass è convinto che la crisi dell'eurozona renderà impossibile per i PIIGS evitare il default e che quanto sta accadendo in Europa sia un avvertimento per il Giappone. 


L'intervista è lunga (quasi 25 minuti) ma molto interessante, anche per la diversità di punti di vista tra l'intervistatrice e l'intervistato. L'opinione di Bass sull'investimento in oro è particolarmente tranchant:

"Buying gold is just buying a put against the idiocy of the political cycle. It's That Simple"

Come salvare l'Italia e l'euro?

Evitare la fine dell'euro e garantire a Italia e Spagna il finanziamento a costi sostenibili
richiede circa 5-800 miliardi di euro: molto ma ancora alla portata di un'iniziativa congiunta dell'EFSF, del Fondo Monetario internazionale e della BCE. Questa è l'opinione degli analisti di Barclays nel report che vi riproduco qui sotto (grazie a scribd.com). Gli analisti osservano peraltro come il vincolo auto-imposto che la BCE intervenga solamente con acquisti di obbligazioni sul mercato secondario ne indebolisca considerevolmente l'azione: è all'asta che si fissa il tasso al quale i paesi debitori dovranno onorare il debito, e non sul mercato secondario.

11.24.11 Euro Themes What Will It Take to Save Italy and the Euro

Aspettando gli eurobond e l'accordo sul debito U.S.A.

Il Wall Street Journal osserva come la situazione politica ricordi da vicino la crisi di fine luglio-inizio agosto, quando la sterilità del dibattito sul debt ceiling fornì la scusa all'agenzia di rating Standard and Poor's per il downgrade del debito sovrano statunitense. Entro mercoledì il comitato bipartisan dovrebbe trovare un accordo da ratificare in Senato per l'abbassamento del debito di almeno 1200-1500 miliardi di dollari. E' sempre più improbabile che ciò accada e le conseguenze sui mercati non dovrebbero tardare a farsi sentire.

For investors, the supercommittee deadline is an unwelcome throwback to the summer, when wrangling over the debt ceiling continued to the eleventh hour and eventually resulted in Standard & Poor's downgrading the U.S.'s credit rating. Then, as now, many investors had been more focused on troubles in Europe, only belatedly realizing the threat being posed to markets, Mr. Doss says.
The biggest unknown, says Erin Browne, director of global macro trading at Citigroup, is how much the continuing wrangling further undermines investor confidence in policy makers.
"The market is concerned about the fact that there's a seeming failure on a global level for policy makers to come to decisions in times of need," Ms. Browne says. "Investors want to see that, at least in times of crisis, Congress can come together."
A loss of faith in political leadership has been a hallmark of the past few months. The Dow Jones Industrial Average tumbled 16% between July and early October amid worries about the impact of the U.S. downgrade, the stalling economy and growing troubles in Europe. Since then, the gains have been driven by hope for progress in Europe as well as evidence of an improving U.S economy.
Most investors and analysts had been anticipating the so-called supercommittee would achieve what RBC Capital Markets chief U.S. economist Tom Porcelli calls "partial success," finding about $1.2 trillion in cuts. But, on Sunday, even that appeared unlikely, leaving open the prospect automatic triggers could kick in to make those budget cuts anyway—largely in federal programs and defense spending.
C'è poi il rischio che la mancanza di un accordo provochi ulteriori tagli del rating del debito americano: 
Still, a credit downgrade, especially by Moody's Investors Service or Fitch Ratings, could have severe consequences, investors said. Such a move would lower the U.S. government's average rating, which remains at triple-A even after the S&P downgrade in August. Many funds are legally obliged to hold only triple-A-rated securities in their portfolios, so a further downgrade could force these funds to liquidate their Treasury holdings.
Nel frattempo in Europa riprende quota l'ipotesi di emettere Eurobond: ancora una volta l'ostacolo viene dalla Germania, ma è chiaro a tutti l'inefficacia dell'EFSF e se non si vuole che la BCE monetizzi il debito dei PIIGS non sembrano esserci molte alternative - tranne la dissoluzione della zona euro...Come è noto ci sono tre versioni possibili: 

Three Visions of Euro Bonds

  • National bond issuance ceases. Euro-zone governments raise new funds in euro bonds, guaranteed jointly by all 17 members. Existing bonds are converted into euro bonds.
  • National governments raise funds as euro bonds, guaranteed jointly by the 17 members, up to a certain limit. Beyond that, governments issue national bonds.
  • National governments raise funds as euro bonds up to a ceiling. Unlike in the first two options, the bonds are backed by limited guarantees from the 17 euro-zone states.

La terza ipotesi è quella meno indigesta per la Germania e gli altri paesi virtuosi, e anche quella maggiormente compatibile con i trattati europei già in vigore. Basterà?

Bye bye eurozona?

Martin Essex sul Wall Street Journal descrive la brutta giornata di ieri:


In the European debt markets on Tuesday, French, Spanish and Belgian 10-year bond yield spreads over German bunds hit new euro-era highs, meaning the extra yield demanded by investors to buy those countries’ bonds rather than safe-haven Germany’s hit the highest levels in modern times. Italian 10-year bond yields also popped back above the 7% crisis level, despite buying by the euro-zone’s bailout fund.
On the other side of the coin, 10-year U.K. gilts, seen as a safe haven alongside German bunds, fell to a new record low yield of just 2.13%.
Over in the market for credit default swaps, the cost of insuring Italian, Spanish, French and Belgian debt against default shot to fresh record highs while Italian CDS hit the 600 basis points level for the first time. But worrying as all this is, it’s nothing to the signs that even triple-A rated countries such as the Netherlands, Finland and Austria are not immune from contagion.
Concerns about Austria can perhaps be explained by that country’s historic ties to Hungary, (...)
But why the Netherlands, where Dutch CDS closed in on February 2009’s record high? “The focus on France has been high in the last couple of weeks but the aggressive widening in Dutch and Finnish paper could potentially mean that the crisis is about to escalate to a new, more dangerous level,” interest rate strategists at the Royal Bank of Scotland said in a note to clients.
Sul Financial Times oggi Martin Wolf commenta il lavoro che aspetta il governo Monti: sarebbe bene che i sacrifici che ci attendono non fossero inutili, ma questo non dipende dalle decisioni prese a Roma.
Yet what Mr Monti must do is enormously tough. As Gavyn Davies argues, Italy might need to tighten fiscal policy by more than 5 per cent of gross domestic product, to reverse the widening spreads and start bringing gross public debt down from its exalted level of over 120 per cent of GDP. Given the inevitable adverse effects on output, the attempted tightening would have to be greater than this. Yet investors are unlikely to regain confidence in Italian debt if its economy does not recover. Austerity is not enough.
The social and political unrest triggered by the envisaged structural reforms, particularly those affecting the labour market, will also shake confidence.(...)
The chances that this is going to work smoothly are not high. The turnround period is going to be many years. (...).
Mr Monti is going to need a great deal of luck. He is also going to need an enormous amount of help, of three kinds: first, at least backstop financing for the rollover of sovereign debt, to the tune of nearly €1,000bn ($1,400bn); second, profitable and dynamic external markets; and, finally, a credible strengthening of the political underpinnings of the union, sufficient to make a break-up inconceivable. All of these are going to depend on bold German decisions. They are also going to depend on the ECB. If it allows slow growth, let alone an outright recession, to grip the eurozone, the chances for big peripheral members are grim. Italy is not little Ireland. That should be obvious to everybody.
The eurozone has fiddled until Rome itself started to burn. With the new government, it has what may turn out to be a last chance to put out the fire. Yes, it is conceivable that Italy would remain in the eurozone even after a default. But that cannot be likely. In any case, an Italian default would batter bond markets across the continent and banks across the world. The time for too little too late has passed. What is needed, instead, is “too much, right now”. Power brings responsibility. Germany alone has the power. It is up to it to exercise the responsibility.

Sulle responsabilità della BCE vi segnalo anche questo commento sul NYTimes di ieri

Is it time for the European Central Bank to be as generous to countries as it is to banks?
Since the beginning of the financial crisis, the central bank has been lending euro area banks as much money as they want, trying to maintain the liquidity — or continual flow of money — that is the lifeblood of the global financial system.
But because the central bank has refused to offer the same easy lending service to countries like Italy and Spain, it is not confronting the euro area’s most fundamental problem — a sell-off of debt from the troubled countries that is pushing their borrowing costs to dangerous levels.
Secondo il NYTimes 
Italy, unlike Greece, is solvent, in that it has the economic resources to manage its debts. That is why many economists say it makes sense to protect Italy from a temporary inability to meet its cash-flow obligations. And with marketplace trust being a top component of getting access to money, the reassurance that the central bank stood ready to step in as a lender to governments might be enough to keep the central bank from having to actually take that action.
But as long as worry continues that Italy may not be able to service its debt, Italian bonds are losing value as interbank currency — a big disadvantage for banks in Italy or France that own tens of billions in Italian debt. Last Tuesday, LCH Clearnet, a company that acts as an intermediary in bond and other trading, said it would impose a steeper discount on Italian bonds used as collateral.
As a central bank, the E.C.B. could theoretically use its ability to print money to buy huge amounts of debt from Italy and other countries. That would drive down their borrowing costs and ensure that they could continue to service their debts — that they would remain liquid, in other words.
The central bank’s charter does not allow it to buy bonds directly from national treasuries. And yet, the central bank can and does do essentially the same thing, by buying government bonds on the open market.
Since last year, the bank has spent 187 billion euros intervening in bond markets. But the relatively modest sums, less than 10 percent of the central bank’s total balance sheet, have not been enough to prevent yields on Italian bonds from rising.
If the interest rates that Italy must pay to borrow remain at their current levels, the government could eventually go bankrupt.
The only limit to the central bank’s ability to create money is a psychological one — the fear of setting off too much inflation. Mainstream economists, though, do not see any risk of significant inflation under current circumstances. The euro area is headed for recession, unemployment is rising and factories are not producing as much as they could. That is why economists tend to encourage the bank to put more money into circulation.
Mr. Draghi seems to be in agreement on at least the point that inflation is not a big threat right now, which is why his first act as the bank’s president was to announce a cut in short-term interest rates.
But if the central bank were to step up its bond buying, it would continue to encounter the shrill opposition of Germany, which has a fear of inflation steeped in history. And Berlin’s voice on such matters is hard for Mr. Draghi to ignore, as German financial support is essential to the survival of the euro area.

Modeste proposte per l'Italia ma anche per la BCE

Il New York Times ha dedicato qualche giorno fa un editoriale alla crisi italiana: punta il dito sulla necessità di riforme che rilancino la nostra economia (secondo l'Economist negli ultimi 10 anni gli unici paesi al mondo che sono cresciuti meno dell'Italia sono Haiti e lo Zimbabwe !) ma anche sulla necessità che la BCE svolga il ruolo di prestatore di ultima istanza:
 Italy, the euro-zone’s third biggest economy, after Germany and France, is too big to be rescued by the European bailout fund and too big to fail without, most likely, taking down the euro itself. Italy’s essential problem is not high deficits, or even high debt, but years of dismally slow growth, which makes the debt harder to pay off and investors more skeptical about its continued ability to repay. That’s why interest rates are rising, compounding the repayment problem.
The only European institution still potentially capable of halting this cascading crisis is the European Central Bank. Only the central bank can print euros in unlimited quantities and use them to buy enough Italian bonds to bring the interest rates down from more than 7 percent to more sustainable levels. Essentially, the bank must become the lender of last resort, printing as much money and buying enough Italian debt to stabilize the situation to allow time for longer-term remedies. While such a move cannot guarantee an end to the panic selling of Italian bonds, it is perhaps the only option left.
Until now, the bank has hesitated to play this role because it has no clear authority under European Union rules, but there are no clear prohibitions against action. Chancellor Merkel and President Sarkozy, having failed so miserably to prevent this crisis, should be publicly urging the central bank’s new president, Mario Draghi, to take these necessary steps. Yet they are still making electoral calculations that will be beside the point should Italy succumb to the debt crisis and the European Union slide into deep recession. Their refusal to think and act responsibly is having a damaging effect on world markets.
Secondo Krugman l'eccessiva forza dell'euro e  l'impossibilità di finanziare il debito italiano e spagnolo in una moneta debole sono all'origine della crisi:

First, if you look around the world you see that the big determining factor for interest rates isn’t the level of government debt but whether a government borrows in its own currency. Japan is much more deeply in debt than Italy, but the interest rate on long-term Japanese bonds is only about 1 percent to Italy’s 7 percent. Britain’s fiscal prospects look worse than Spain’s, but Britain can borrow at just a bit over 2 percent, while Spain is paying almost 6 percent. 

What has happened, it turns out, is that by going on the euro, Spain and Italy in effect reduced themselves to the status of third-world countries that have to borrow in someone else’s currency, with all the loss of flexibility that implies. In particular, since euro-area countries can’t print money even in an emergency, they’re subject to funding disruptions in a way that nations that kept their own currencies aren’t — and the result is what you see right now. America, which borrows in dollars, doesn’t have that problem.
The other thing you need to know is that in the face of the current crisis, austerity has been a failure everywhere it has been tried: no country with significant debts has managed to slash its way back into the good graces of the financial markets. For example, Ireland is the good boy of Europe, having responded to its debt problems with savage austerity that has driven its unemployment rate to 14 percent. Yet the interest rate on Irish bonds is still above 8 percent — worse than Italy.
The moral of the story, then, is to beware of ideologues who are trying to hijack the European crisis on behalf of their agendas. If we listen to those ideologues, all we’ll end up doing is making our own problems — which are different from Europe’s, but arguably just as severe — even worse.
Brad De Long insiste poi sulla necessità che la Fed acquisti le obbligazioni dei PIIGS mantenute in portafoglio
dalle banche statunitensi per costruire un firewall e impedire che il contagio produca un credit crunch nell'anemica economia U.S.A.

Se pensate che queste siano esagerazioni di economisti troppo liberal allora potete leggere questo post di Roubini sul suo blog sul sito del Financial Times, significativamente intitolato Why Italy’s days in the eurozone may be numbered. Le conclusioni sono praticamente le stesse: 
... Italy may, like other periphery countries, need to exit the monetary union and go back to a national currency, thus triggering an effective break-up of the eurozone.
Until recently the argument was being made that Italy and Spain, unlike the clearly insolvent Greece, were illiquid but solvent given austerity and reforms. But once a country that is illiquid loses its market credibility, it takes time – usually a year or so – to restore such credibility with appropriate policy actions. Therefore unless there is a lender of last resort that can buy the sovereign debt while credibility is not yet restored, an illiquid but solvent sovereign may turn out insolvent. In this scenario sceptical investors will push the sovereign spreads to a level where it either loses access to the markets or where the debt dynamic becomes unsustainable.
So Italy and other illiquid, but solvent, sovereigns need a “big bazooka” to prevent the self-fulfilling bad equilibrium of a run on the public debt. The trouble is, however, that there is no credible lender of last resort in the eurozone.

Il bazooka della BCE viene invocato anche da Richard Barley sul Wall Street Journal

The clamor from the markets is deafening: They believe only the European Central Bank can end the euro crisis and want it to unveil a crisis bazooka. The ECB's current bond-purchase program is backfiring and encouraging private investors to dump paper. To stop the rot, one popular idea is that the ECB should commit to target a specific yield level for Italian bonds, if necessary by making unlimited purchases, in the same way the Swiss National Bank has vowed unlimited intervention to prevent Swiss franc appreciation. (...)  If the ECB committed to cap Italian yields at, say, 5% at the 10-year maturity, it might run into some initial selling, as some investors took the chance to exit from positions and others sought to test the ECB's commitment. But if the cap were found to be credible, investors could be tempted to buy Italian bonds given the higher level of yields than available elsewhere.

Intanto da ieri sera il professor Monti ha il mandato di formare un nuovo governo. Sul Sole 24 Ore ieri Luigi Zingales ha scritto un possibile programma per il nuovo esecutivo: 

Da bravo curatore, Monti non deve fare grandi programmi, ma il minimo delle misure urgenti per rimettere il Paese in grado di funzionare. Proprio perché tecnico il governo potrebbe permettersi di fare quelle riforme che i politici sanno necessarie, ma non vogliono fare per paura di perdere le elezioni. Cominciamo dall'eliminazione delle Province e l'accorpamento dei Comuni più piccoli. Proseguiamo poi con il taglio delle pensioni di anzianità e l'introduzione della pensione a 67 anni da subito, per uomini e donne. Per liberare il Paese dai famosi lacci e lacciuoli, il governo Monti dovrebbe liberalizzare le professioni ed abolire il contratto unico. Per liberare l'economia dalla corruzione della politica, Monti dovrebbe privatizzare le municipalizzate, le grandi imprese statali, ed espropriare le fondazioni bancarie, la moderna manomorta ecclesiastica che infetta di politica il mercato del credito e sperpera i nostri soldi. Con queste operazioni dovrebbe essere in grado di riportare il rapporto debito su Pil intorno al 100%, una cifra più gestibile. Per impedire poi che i governi futuri sperperino i sacrifici effettuati, come i governi dopo Ciampi sperperarono quelli del governo Ciampi, Monti dovrebbe inserire una legge che rende obbligatorio il pareggio di bilancio, come ha fatto la Spagna.

Aggiungete pure se volete altre misure di austerità, patrimoniali e quant'altro. Probabilmente non sarebbero sufficienti. Scrive ancora Roubini (le sottolineature sono mie): 


Even a change in Italian government to a coalition headed by a respected technocrat will not change the fundamental problem – that spreads have reached a tipping point, that output is free-falling and that, given a debt to GDP ratio of 120 per cent, Italy needs a primary surplus of over 5 per cent of GDP just to prevent its debt from blowing up.
Output now is in a vicious free fall. More austerity and reforms – that are necessary for medium-term sustainability – will make this recession worse. Raising taxes, cutting spending and getting rid of inefficient labour and capital during structural reforms have a negative effect on disposable income, jobs, aggregate demand and supply. The recessionary deflation that Germany and the ECB are imposing on Italy and the other periphery countries will make the debt more unsustainable.
Even a restructuring of the debt – that will cause significant damage and losses to creditors in Italy and abroad – will not restore growth and competitiveness . That requires a real depreciation that cannot occur via a weaker euro given German and ECB policies. It cannot occur either through depressionary deflation or structural reforms that take too long to reduce labour costs.
So if you cannot devalue, or grow, or deflate to a real depreciation, the only option left will end up being to give up on the euro and to go back to the lira and other national currencies. Of course that will trigger a forced conversion of euro debts into new national currency debts.
The eurozone can survive with the debt restructuring and exit of a small country such as Greece or Portugal. But if Italy and/or Spain were to restructure and exit this would effectively be a break-up of the currency union. Unfortunately this slow-motion train wreck is now increasingly likely.
Only if the ECB became an unlimited lender of last resort and cut policy rates to zero, combined with a fall in the value of the euro to parity with the dollar, plus a fiscal stimulus in Germany and the eurozone core while the periphery implements austerity, could we perhaps stop the upcoming disaster.
