Nor is this rescue fund any more than chemotherapy for the cancer eating away at the foundations of monetary union. It is not a cure. The rot set it when the South joined EMU before it was ready to cope with ultra-low interest rates or match German wage-bargaining. The ECB made matters worse by gunning M3 at an 11pc rate during the bubble. Club Med lurched from credit boom to bust. It is now trapped in debt deflation at an over-valued exchange rate, like Argentina with its dollar peg in 2001 until air force helicopters rescued President De La Rua from the roof of the Rosada.

The answer to this -- if the objective is to save EMU -- is for Germany to boost its growth and tolerate higher `relative' inflation. This would allow the South to close the gap without tipping into a 1930s Fisherite death spiral. Yet Europe will have none of it. The weekend deal demands yet more belt-tightening from the South. Portugal is to shelve its public works projects. Spain has pledged further cuts. As for Germany, it is preparing fiscal tightening to comply with the new balanced budget amendment in its Grundgesetz.

While each component makes sense in its own narrow terms, the EU policy as a whole is madness for a currency union. Stephen Lewis from Monument Securities says Europe's leaders have forgotten the lesson of the "Gold Bloc" in the second phase of the Great Depression, when a reactionary and over-proud Continent ground itself into slump by clinging to deflationary totemism long after the circumstances had rendered this policy suicidal. We all know how it ended.
