Martin Wolf , the Financial Times 's top economics commentator, argues that, essentially, the eurozone proved its worth during the global economic crisis of 2007-2009. Had it not existed, independent currencies surely would have dropped significantly, and might have set off a worse problem across the continent. But now, more trouble looms as the economies of some eurozone countries are " locked into competitive disinflation against Germany, the world’s foremost exporter of very high-quality manufactures." Wolf: In its first decade of existence, the imbalances inside the eurozone (and associated bubbles) finished up by doing massive damage to the credit of the private sectors of the booming economies. But now it is damaging the credit of their public sectors. While risk spreads have fallen in financial markets, those on sovereign debt in the eurozone are an important exception. Spreads over German 10-year bunds have soared from what used to be negligible levels: in the case of Greece, spreads recently reached 274 basis points. The late Charles Kindleberger of MIT argued that an open economy required a hegemon. One of its roles is to be spender and borrower of last resort in a crisis. The hegemon, then, is the country with the best credit. In the eurozone, it is Germany. But Germany is a lender, not a borrower, and is sure to remain so. This being so, weaker borrowers must fulfil the role, with dire results for their credit ratings. Where does that leave peripheral countries today? In structural recession, is the answer. At some point, they have to slash fiscal deficits. Without monetary or exchange rate offsets, that seems sure to worsen the recession already caused by the collapse in their bubble-fuelled private spending. Worse, in the boom years, these countries lost competitiveness within the eurozone. That was also inherent in the system. The interest rates set by the European Central Bank, aimed at balancing supply and demand in the zone, were too low for bubble-fuelled countries. With inflation in sectors producing non-tradeables relatively high, real interest rates were also relatively low in these countries. A loss of external competitiveness and strong domestic demand expanded external deficits. These generated the demand needed by core countries with excess capacity. To add insult to injury, since the core country is highly competitive globally and the eurozone has a robust external position and a sound currency, the euro itself has soared in value.
