This week, the worried finance ministers of the countries of the International Monetary Fund are meeting equally worried bankers in Nairobi to try to solve international exchange rate problems. The solution that they cobbled together three years ago in Washington was to float. But the pound has floated soggily downwards losing 18% of its value, while the deutschmark has popped up like a champagne cork. Chancellors and their like are paid to worry about that - why should it trouble the rest of us?
