Economists who now see American troubles spreading around the world are predicting that foreign central banks will ignore the gathering inflation threat and follow the Fed down the rate cutting path. Similarly, they argue that since the downturn began here, the U.S. recovery will likely be underway while the rest of world is still decelerating. These assumptions have prompted a rally in the dollar, a sell-off in gold, commodities and foreign stocks, and have cast doubts on the ability of foreign economies to “decouple” from the United States. Investors should not take the bait.
