International challenges spell good and bad news for the European Central Bank. On the positive side, the credit crisis has given the independent ECB and Jean-Claude Trichet, its president, unexpected authority on the world stage. Most observers agree the 10-year-old economic and monetary union has so far moderated the direct fall-out of the financial crisis for eurozone members. On the negative side, Europe this year faces probably the worst recession since the second world war. Depending on how Emu members react, latent nationalism within the single currency area may emerge as a disruptive force.

Battle lines are being drawn between the “stability first” principles of Europe’s strongest economy, Germany, and the more activist growth policies favoured by France. Mr Trichet, a veteran of fierce battles with the Bundesbank as head of the French Treasury in the early 1990s, has emerged as heir to the German central bank’s anti-inflation throne. The ECB’s president and decision-making council have come under sporadic pressure from European politicians to soften their monetary stance. After the mid-September collapse of Lehman Brothers, the US bank, the ECB cut interest rates three times between October and December – the first reductions since Mr Trichet took office in 2003. But despite recent signs of further economic weakening, there are strong indications that Mr Trichet will continue to garb himself in a mantle of Bundesbank-like firmness.
