I am becoming ever more worried. I never expected much from the Europeans or the Japanese. But I did expect the US, under a popular new president, to be more decisive than it has been. Instead, the Congress is indulging in a populist frenzy; and the administration is hoping for the best.

If anybody doubts the dangers, they need only read the latest analysis from the International Monetary Fund.* It expects world output to shrink by between 0.5 per cent and 1 per cent this year and the economies of the advanced countries to shrink by between 3 and 3.5 per cent. This is unquestionably the worst global economic crisis since the 1930s.

One must judge plans for stimulating demand and rescuing banking systems against this grim background. Inevitably, the focus is on the US, epicentre of the crisis and the world's largest economy. But here explosive hostility to the financial sector has emerged. Congress is discussing penal retrospective taxation of bonuses not just for the sinking insurance giant, AIG, but for all recipients of government money under the troubled assets relief programme (Tarp) and Andrew Cuomo, New York State attorney-general, seeks to name recipients of bonuses at assisted companies. This, of course, is an invitation to a lynching.
