Even if the US’s massive financial rescue operation succeeds, it should be followed by something even more far-reaching – the establishment of a Global Monetary Authority to oversee markets that have become borderless.

Washington recognises that the crisis has become global. Hank Paulson, Treasury secretary, has said that foreign banks operating in the US will be eligible for federal assistance and he is urging other nations to fashion their own bail-out programmes. Central banks have also been synchronising injections of funds into markets. These should be steps to a more comprehensive international response designed not just to extinguish the current fires, but to rebuild and maintain the capital markets for the longer term.
