“A crisis is a strange way to celebrate an anniversary.” This is the wry judgment of Erik Bergl?f, chief economist of the European Bank for Reconstruction and Development.* Yet a crisis is what we see in countries that began the march from communism two decades ago. So, has capitalism failed, as communism did? In a word, “no”. Some transition countries are in crisis; transition is not. The same judgment applies elsewhere: capitalist countries are in crisis; capitalism itself is not. But reform is necessary. The great virtue of liberal democracies and market economies is their ability to reform and adapt. They have shown these qualities before. They must do so once again.

For those born, like me, shortly after the second world war, the cold war was the defining intellectual and political struggle of our lifetimes. With the collapse of communism ended a catastrophic epoch of millenarian politics and the delusion of a rationally planned economy. The freedom offered by democracy and the prosperity supplied by markets won. But the fact that communism expired not with a bang, but with a whimper, we owe largely to Mikhail Gorbachev.

Yet 2009 is a sobering year from which to look back. A year ago, capitalism careered over a cliff. With vast effort, states have put it back on the road. According to Piergiorgio Alessandri and Andrew Haldane of the Bank of England, in a superb new paper**, the total gross value of interventions on behalf of banks has been $14,000bn (€9,400bn, ￡8,400bn). This is state socialism.
