Turmoil in the US’s financial markets got the top billing in news reports about the recent meetings of the world’s leading international policymakers in Washington. Virtually everyone expressed concern that the housing slump and the financial crisis triggered by the subprime mortgage market would significantly slow down the US economy, and perhaps the world economy. But there is a surprising silver lining. Signs of it were revealed by the absence of reporting on the big bugaboo of the past few years: the US current account deficit.

The good news is the recent reversal of the steady upward climb in the current account deficit. During the past three quarters for which we have data the deficit has been cut by $119bn, falling from about 6 per cent of gross domestic product to 5 per cent, and the adjustment appears to be continuing.
