If the eurozone were to shrink, Germany's once-captive markets would become too poor to import: and the rapid appreciation of a stronger euro would make its exports much pricier
Germany last week found itself able to borrow for two years at the astonishingly low rate of 0.07%. Very nice too: but surely the real message Angela Merkel and her colleagues must take from the successful auction of those zero-coupon schatz bunds is that the single currency simply isn't working.
All the money wants to flow in one direction: towards Germany. It is only the efforts of the European Central Bank, as a giant recycler of liquidity to dry areas of the eurozone banking system, that is ensuring a stability of sorts. This position can't be sustained.
