Over the past two years, the euro crisis has morphed from a sovereign crisis in a peripheral country (Greece), to a banking crisis, and back to a sovereign crisis in core countries (Italy, Spain). At every turn a "solution" is devised whose purpose is to "save" the euro but whose actual result is simply to push the crisis into new and more desperate terrain. The latest solution - aggressive easing by the ECB - means that the next phase of the euro disaster will be a balance of payments crisis. Indeed, the ECB's change of operating procedures undeniably "solves" last year's problem of eurozone governments financing themselves. But what kind of solution is it when, as Jacques Rueff put it 50 years ago, the ECB's move amounts to "financing expenditures which have no return with money that does not exist"? The highest-odds scenario is thus that the bloated eurozone public sector, having guaranteed its financing for the next three years, will stop all effort at reform, and that the southern European countries will become even less competitive than they are now. In turn this means that -- barring a collapse in oil prices -- their dollar trade deficits will grow larger and that a classic balance of payments crisis is thus right around the corner.
So far, this crisis has not materialized because of the generosity of the Fed, whose swap lines already total US$100bn. To all intents and purposes, the Fed is now financing not only the US budget deficit but also the southern European trade deficits, while the ECB gets to carry the exchange rate and solvency risks. (This Fed-dependence carries a delicious historical irony: one of the prime goals of the euro architects was to create a powerful alternative to the dollar, ensuring that Eurocrats would never again be subservient to Washington. Yet today, thanks to the euro, Europe must go cap in hand to Washington to stay solvent).
