The danger for Germany is that America will lose patience, with unpredictable consequences. The US Federal Reserve is currently propping up the European banking system in a variety of ways, including dollar swaps.

Markets across the world ignored the mixed signals about the true scope of EU rescue measures, convinced that EU leaders have a "grand plan" up their sleeves and will unveil the details after the Bundestag has voted on Thursday on the earlier July deal to revamp the fund.

France's CAC-40 surged by 5.7pc, led by a 17pc rise for Societe Generale. Germany's Dax was up 5.3pc. The FTSE 100 jumped 4pc in London, the biggest one-day rise this year. Oil jumped almost $4 in New York to $88 a barrel.

In Berlin, Chancellor Angela Merkel was fighting for her political life as the rump of lawmakers from her coalition vowed to reject the EFSF package, though the latest tally suggests she may squeeze by with her own majority. Angry dissidents suspect that secret plans are being withheld until after the vote.

Greek premier George Papandreou told German business leaders that his country would honour its austerity pledges, but also issued a veiled warning. "The persistent criticisms levelled against Greece are deeply frustrating, not only at the political level, where a superhuman effort is being made to meet stringent targets in a deepening recession, but frustrating also for the Greeks, who are making these painful sacrifices."

"Drastic measures have had a dramatic impact on the living standards of our citizens. Many Greeks feel they have little left to give. If people feel only punishment and scorn, this crisis will become a lost cause," he said.

Mr Papandreou's Pasok party passed a crucial vote on Tuesday to raise property taxes, but at a high political price. The party's approval rating has fallen to 15pc in the latest Mega poll.

However, Greece was confronted with a new threat as it emerged that several eurozone members are demanding the private sector absorb bigger losses than originally agreed as part of a second bail-out.

A deal struck in July would see creditors taking 21pc losses on their Greek debt holdings, adding around €45bn to the €109bn proposed second rescue. However, more than a third of the 17-member single currency bloc are now said to be demanding bigger haircuts for the private sector. Talk of revisions to the second bail-out may renew default fears as the IMF has yet to re-engage with Greece over the latest €8bn tranche of its initial €110bn rescue. Greece is at risk of running out of money by October 8, though analysts say the payment is almost certain to be made whether or not Greece has complied fully with the terms.

Greece has a trump card in rescue talks with the IMF-EU "Troika". If it opts for a "hard default", it could set off a chain reaction. Lorenzo Bini-Smaghi, an ECB board member, said those arguing that Europe's banks could withstand a Greek default are misguided. "Similar views were held before Lehman. Those who say this have no idea how contagion works," he said.

Analysts say the Troika will have to approve the next €8bn tranche of aid for Athens in October whether or not Greece has complied fully with the terms. It cannot risk a showdown before Europe's banks have beefed up their capital base, or before the EFSF is fully equipped to defend the rest of the system.

Like a forced marriage, Europe and Greece must kiss and pretend.
