"The euro should not exist," said Stephane Deo from UBS. It creates more costs than benefits for the weak. Its "dysfunctional nature" was disguised by a credit bubble. The error is now "painfully obvious".
My solution - like that of Hans-Olaf Henkel, the ex-head of Germany's industry federation (BDI) - is to split EMU into two blocs, with France leading a Latin Union that keeps the euro. This bloc would devalue but not by 60pc, yet uphold its euro debts intact. The risk of default and banking crises would decrease, not increase.
