In 1978, Alfred Kahn, an adviser on inflation to President Jimmy Carter, used the word “depression”. So angry was the president that Mr Kahn started to call it “banana” instead. But the recession Mr Kahn foretold happened all the same. The same may well happen with nationalisation. Indeed, it already has: how else is one to describe the actions of the federal government in relation to Fannie Mae, Freddie Mac, AIG and increasingly Citigroup? Is nationalisation not already the big financial banana?

Much of the debate is semantic. But underneath it are at least two big issues. Who bears losses? How does one best restructure banks?

Banks are us. Often the debate is conducted as if they can be punished at no cost to ordinary people. But if they have made losses, someone has to bear them. In effect, the decision has been to make taxpayers bear losses that should fall on creditors. Some argue that shareholders should be rescued, too. But, rightly, this has not happened: share prices have indeed collapsed. That is what shareholders are for.
