What was inconceivable only a couple  of months ago has now happened: EU leaders have 
agreed  a massive €500  billion bailout package for eurozone countries facing sovereign debt problems –  on top of the €110 billion already committed in a separate rescue package for  Greece. An additional €250 billion could also come from the IMF should things  get really sticky.
You have to go back pretty far in  history to find a time when Europe’s leaders  have been so desperate. And you can see why. Markets remained unconvinced of the  adequacy of the original rescue package for Greece, and you could sense some serious anxiety  over the risk of an escalating sovereign debt crisis, involving  Spain, Portugal, Ireland and Italy (The UK is  not exactly immune either, although its situation is 
different). In the last week, the EU elite realised in horror that their flagship project  might actually be on the verge of collapsing under the weight of its own  contradictions.
Of course, these kinds of tensions  are exactly what the sceptics always warned against, and those who blindly  argued in favour the Single Currency have some serious soul-searching to do. But  it’s still in everyone’s interest that the eurozone sorts out its mess, and the  massive bailout package agreed over the weekend seems to have calmed the  markets - for now.
As an event in the EU’s history,  what happened over the weekend is absolutely extraordinary on so many different  levels:
1) Until very recently, Eurozone bailouts were considered  a no-go, since both the letter and the spirit of the EU Treaties  simply don’t allow for them. Just consider that as late as March this year,  Angela Merkel 
said, "We have a Treaty under which there is no possibility of  paying to bailout States in difficulty”.
But as we noted many times 
before,  EU law has a tendency to become irrelevant in times of crisis and the once  heralded no bailout principle has now been watered down to the point of becoming  meaningless. Having said that, the ‘big’ bailout fund still has some ways to go  before it is approved by national parliaments and has passed all legal hurdles,  as Edmund Conway points out on his Telegraph 
blog.
2) The scale of  the bailout is mind-boggling. Again, consider that only a few  weeks ago, the amount 
discussed  was closer to €30 billion in a one-off bailout for 
Greece  (and before that €20-25 billion). Then, on May 3
rd, that amount had  almost quadrupled. As Italian Foreign Minister Franco Frattini 
put it,  “It was necessary to intervene right away to help Greece.  To avoid damage we initially talked about 50 billion euros, but decided on 110  billion only 10 days later.” And roughly a week later the deal had been rolled  out to all eurozone countries, now involving hundreds of billions of euros.
You can forgive people for wondering  where this will end. Particularly given that throwing good money after bad in  this kind of way isn’t really solving the fundamental problems of the weak  solvency, competiveness and productivity that weaker eurozone countries are  currently facing. So this deal could easily spiral out of control and see  UK and European taxpayers becoming  exposed to ever growing debt burdens of governments over which they have no  democratic control whatsoever. This simply isn’t  sustainable.
3) EU leaders are  basing parts of the bailout on Article 122 of the EU  Treaties. This is profoundly dishonest and  involves a huge legal stretch.  Article 122 states that,
"Where a member state is in  difficulties or is seriously threatened with difficulties caused by natural  disasters or exceptional occurrences beyond its control, the Council, on a  proposal from the Commission, may grant, under certain conditions, Union  financial assistance to the member state."As we’ve stated before, the European  Council has previously 
said   that any use of this article must be compatible with the no bailout rule in the  EU Treaties. This interpretation is now being completely ignored.
Telegraph journalist Bruno  Waterfield summarises the issue well on his EUobserver  blog,
“'Exceptional occurrences beyond  control’? This is a lie. A whopping, howling lie told to us by Europe’s political class. This crisis is a product of  human agency, the choices and decisions taken by people facing circumstances  that are man-made and, thus, susceptible to political intervention. To use a  legal clause designed for earthquakes or potentially extreme unforeseen  circumstances that threaten the existence of one member state to save the skins  of the EU’s political class is profoundly deceitful – quite aside from being  legally dodgy."4) What we  were told would never happen, has now occurred - British  taxpayers have become directly 
liable  for the debts of eurozone governments. Part of the rescue package involves  extending a special fund, previously available only for non-eurozone members Latvia and  Hungary. This so-called 'stability  fund' will allow the EU Commission to borrow up to €60 billion on international  markets, in addition to the €50 billion that was already in the pot, using the  EU budget as collateral. If a receiving country fails to pay back the loan, all  27 EU member states would be forced to pay into the EU budget to cover the  default, meaning that British taxpayers would be liable for about 13 percent of  any losses (corresponding to the UK’s share of the EU budget).  Alistair Darling maintains that the maximum loss to British taxpayers would  “only” be €8 billion.
Mr Darling said yesterday that  the UK will never  “underwrite” the euro, but that is exactly what is happening (although the  UK will be left out of the bulk of  the rescue package, the €440 billion scheme of bilateral eurozone  loans).
5) Eurozone leaders took a decision involving  non-eurozone countries but without the latter being represented.  Alistair Darling has said he supports the 
UK’s  inclusion in the stability fund, but in reality he doesn’t have much of a  choice. The decision was effectively taken at the eurozone summit on Friday and  since the deal was decided using QMV (as it was based on Article 122), the  
UK didn’t have a veto when the deal  was sealed in the Council of Ministers on Sunday. This is another thing that  never was supposed to happen. The fact that the 
UK only has a caretaker government in place at the moment didn’t exactly help either.
6) Germany  had to cave in to French demands on the scope and details of the  bailout. According to 
FAZ,    following the deal, Nicolas Sarkozy triumphantly said that "95 percent" of the  agreed bailout package "reflect French proposals…at last we have decided to give  the eurozone a real economic government." This whole arrangement has Sarkozy’s  fingerprints all over it. Or as the Brussels correspondent for 
FAZ, Werner Mussler 
noted yesterday, "The facts are: Sarkozy has achieved what he  always wanted: the fundamental decisions of the eurozone will be taken by the  leaders of the euro states."
7) The line  between fiscal and monetary policy has been blurred. Arguably  the most significant move over the weekend was the ECB’s decision to buy  eurozone government and private debt. In doing so the ECB clearly bowed to  political pressure, compromising its independence while for the first time getting  involved in fiscal policy – akin to ‘quantitative easing’ in the UK (The EU  Treaties prevent the ECB from buying bonds directly from governments, so to  circumvent the rules it will instead be buying debt second-hand from banks).  This is huge. In combination with the other moves towards fiscal EU  centralisation (including more EU budgetary controls), it’s now beyond doubt  that we’re seeing the emergence of an economic government for the eurozone.
Will the Germans accept this brave  new eurozone? That’s far from clear. Die Welt set out its position in a  comment piece  
yesterday:
“This [the involvement of the ECB]  will harm the stability of the euro in the longterm and bury the German belief  in the stability of the euro. The costs of this error are not yet  foreseeable...The German conceptions of stability principles, responsibility and  a monetary policy independent of political influence are coming increasingly  under pressure. The idea of an economic government with right of intervention in  national economic policy, transfers of debt and a politically influenced central  bank is on its way."So EU leaders have given themselves  some breathing space, but what have they actually solved? And at what cost, in  the medium and long term, to the EU economy and to European  democracy?
As the FT argued today:
“There can be no more pretence that monetary union respects the premise on which it was sold to European citizens, Germans in particular. There is a real chance that a euro member’s failure to pay its debts will land neighbours or the ECB with losses that can only amount to fiscal transfers or money-printing. Strict surveillance and ECB independence was meant to make it impossible to end up in this situation; both have been undermined...Pooling more sovereignty than it ever planned, the eurozone is now at the mercy of its most indebted members’ sovereign decisions.”
