The euro will have broken up before the end of this Parliamentary term, according to the majority of economists surveyed by The Sunday Telegraph.
They believe the single currency is in its death throes and may not even survive in its current membership for a week, let alone the next five years.
Of the 25 leading City economists surveyed, 12 predicted the euro would not survive in its current form this Parliamentary term, compared with eight who suspected it would. Five were undecided.
Two of the eight experts who predicted the currency would survive said it would do so only at the cost of seeing at least one of its members default on its sovereign debt.
Andrew Lilico, chief economist at think tank Policy Exchange, said there was "nearly zero chance" of the euro surviving with its current membership, adding: "Greece will certainly default on its debts, and it is an open question whether Greece will experience some form of revolution or coup - I'd put the likelihood of that over the next five years as around one in four."
Douglas McWilliams of the Centre for Economics and Business Research warned the single currency "may not even survive the next week".
Meanwhile David Blanchflower, professor at Dartmouth College and former Bank of England policymaker, told the Telegraph: "The political implications [of euro disintegration] are likely to be far-reaching - Germans are opposed to paying for others and may well quit."
Four of the economists said despite wider suspicion Greece or some of the weaker economies may be forced out of the currency, the most likely country to leave would be Germany.
The economists also predicted the UK economy will grow by well over a percentage point less next year than the Budget predicted in March.
They believe the Government will borrow almost £10bn less next year than the Treasury previously forecast, despite this weaker growth.
However, they were split on when the Bank of England will raise interest rates with some saying this year and others forecasting 2012 at the earliest.
