I shouldn't write anything about the weakness of the dollar. The governor of the Bank of England, Mervyn King, who has a much better idea of what's going on than I do, said the other day: "I have no idea where exchange rates will go in the future and I have no intention of ever starting to forecast exchange rates." And recently, Alan Greenspan, chairman of the U.S. equivalent, the Federal Reserve Bank, was equally dismissive, citing as evidence the "statistically robust finding that forecasting exchange rates has a success rate no better than that of forecasting the outcome of a coin toss."
Why should two of the world's leading central bankers emphasize the impossibility of predicting exchange rate movements at this particular moment? Because, I suggest, they both sense, though they cannot be sure, that the decline in the value of the U.S. currency could gather pace. If it does, they wouldn't want to be criticized by politicians for not having warned them. A dollar collapse would be an unpleasant experience for the United States itself and for Europe.
In terms of the euro, the dollar has never been lower. Even in the few weeks since President Bush was re-elected, the dollar has dropped by 2.5 percent in euro terms. Altogether it has lost 40 percent of its value in the past two years. The pound has behaved broadly as if it were in the euro camp. That is why we find American holidays good value. That is why British suppliers of goods and services have a hard time exporting to the United States.
This quite substantial decline, with its inevitable effects on trade, has passed largely unnoticed. Of course financial markets are up to speed, and so are companies whose international business is affected. The reason why the rest of us hardly have realized what is going on is that the United States' huge trade deficit has been financed without the least bit of trouble.
