A group of leading economists has warned that the euro may not survive much longer, according to a survey by the London Sunday Telegraph.
The European currency has been hit hard by the debt crisis in countries like Greece, and many analysts have wondered if all of the countries who are involved in the euro agreement will stick with it.
"Possibly Germany will leave. Possibly other central and eastern European countries - plus Denmark - will have joined," said Peter Warburton of consultancy Economic Perspectives. "Possibly, there will be a multi-tier membership of the EU and a mechanism for entering and leaving the single currency. I think the project will survive, but not in its current form."
"The eurozone will lose three or four members -- Greece, Portugal, maybe Ireland, and could break up altogether because of the growing friction between France and Germany," said Tim Congdon of International Monetary Research.
If that agreement does begin to collapse, it could lead to a serious financial crisis in Europe and possibly worldwide.
