NEW YORK (AP) - The dollar slipped Tuesday in choppy foreign exchange trading. Following the lead of U.S. stock prices, the dollar seemed to stabilize Tuesday, before giving way to pressure late in the sesssion. Still, stock price indexes and the dollar both finished only slightly lower, as investors kept watch on political and security-related developments. "Currency markets are running to and fro while they try to figure out the global security situation, and I think that's going to define currency movement for at least the next week if not until the end of the year," said Greg Anderson, financial economist at FleetBoston Financial. "Any sign of heightened security concern causes the dollar to sell off." The Swiss franc, meanwhile, has gained 6 percent on the dollar since the terrorist attacks on the World Trade Center and the Pentagon. On Tuesday, it hit record highs against the euro, a cross Anderson said "isolates the safe-haven componant of Swiss." In trading Tuesday, the dollar ranged between 159.50 and 162.30 Swiss francs, finishing the day at 1.5979, down from 1.6045 late Monday. In late New York trading, the euro was quoted at 92.68 cents, up from 92.44 cents late Monday. Meanwhile, the dollar was quoted at 117.23 Japanese yen, down from 117.73 yen. Elswhere, the central banks of Britain and Japan dropped key interest rates Tuesday to match similar cuts in the United States, Canada and continental Europe after last week's terrorist attacks. Tuesday's cuts came as little surprise after the U.S. Federal Reserve Bank, the European Central Bank, the Swiss National Bank and Bank of Canada slashed their main rates Monday. Though seen as positive, the rate cuts carried minimal impact in currency trading. "When everybody cuts rates at the same time and there are much bigger news stories to fill people's minds, the effects are negligible," Anderson said. "I think that will be what comes out of this whole round of rate cuts: negliable currency movements." Earlier, in Asia, currency traders were wary of possible intervention by Japan's central bank. Japan's Finance Minster Masajuro Shiokawa told reporters on Tuesday that Japanese finance authorities are ready to take action if the yen moves excessively. On Monday, the Bank of Japan intervened in the currency market, buying dollars and selling yen to stem the yen's strength. The dollar also was quoted at 1.5724 Canadian dollars, up from 1.5688. The British pound rose to $1.4684 from $1.4665. Currencies of the 12 countries participating in the euro are no longer traded separately and are tied to the euro by a fixed rate. Based on Tuesday's euro rate, the dollar was worth 2.1105 German marks, down from 2.1158; 7.0784 French francs, down from 7.0960; and 2,089.42 Italian lire, down from 2,094.62.
