He said he believed Greece would elect a government willing to abide by loan conditions imposed by the EU in this month’s elections.
But he said the German economy would begin to weaken in the autumn, making it much harder for Chancellor Angela Merkel to provide further support.
He said leaders did not understand “the nature of the crisis”. He said that while European leaders were focusing on debt levels, the crisis was “more of a banking problem and a problem of competitiveness”.
For this reason, he said, they had “applied the wrong remedy”. “You cannot reduce the debt burden by shrinking the economy, only by growing your way out of it,” he added.
Mr Soros, speaking at a conference in Italy, was referring to the drastic austerity measures that have been implemented across Europe, measures that are now being questioned by a growing number of politicians and commentators.
Without policies to boost growth, which would enable governments to raise revenue to pay down debt, Mr Soros said time was running out for the euro.
“I expect the Greek public will be sufficiently frightened by the prospect of expulsion from the EU that it will give a narrow majority of seats to a coalition that is ready to abide by the current [bailout] agreement,” he said.
However, this would provide only temporary respite, he warned, as the German public becomes less willing to continue bailing out its weaker European neighbours.
“The crisis is likely to come to a climax in the [autumn]. By that time, the German economy will also be weakening, so that Chancellor Merkel will find it even more difficult than today to persuade the German public to accept any additional European responsibilities.
“That is what creates a three-month window.”
