The dollar was higher against the yen and other regional currencies in Asian trading Friday morning as investors reacted calmly to the blasts on mass transit systems in London the day before. The dollar was trading at 112.36 yen Friday morning, up 0.31 yen from late Thursday and above the 112 yen it bought in New York later that day. The euro was unchanged from late Thursday in Tokyo at $1.1934. In New York Thursday, the dollar initially dropped but later made up most of its earlier losses after traders shrugged off concerns about the attacks in London, which killed at least 37 and injured some 700. The pound dropped as low as $1.7403, the lowest it has been since December 2003. It recovered after the interest-rate decisions, and climbed to $1.7416 by late trading in New York, down from $1.7567 in New York late Wednesday. The dollar fell to 1.2984 Swiss francs from 1.3031, and to 1.23 Canadian dollars from 1.2374. Gains on Wall Street and U.S. Treasury yields also helped the dollar recover its ground overnight, while market positioning ahead of Friday's June nonfarm payrolls number also help lift the greenback. Four blasts rocked the London subway and tore open a packed double-decker bus during the morning rush hour Thursday in the worst attack on the city since World War II. "It's not all about these terror attacks," said DZ Bank economist Dorothea Huttanus in Frankfurt of the decline in the British currency. "For the pound, we also had some devastating data from the economic front and the expectations that the Bank of England will have to cut rates very, very soon," she said, referring to disappointing consumer and manufacturing reports from London earlier this week. The Bank of England held its main interest rate at 4.75 percent for an 11th straight month. Lower interest rates can detract from a currency's appeal by reducing the return on the investments in which it is denominated. In Frankfurt, the ECB also kept its key refinancing rate unchanged at 2 percent despite worries about growth and the attacks in London. Bank President Jean-Claude Trichet said he had discussed the situation with U.S. Federal Reserve Chairman Alan Greenspan and with Bank of England head Mervyn King and concluded that financial systems were working normally.
