The dollar hit a three-week high against the yen and rose against the euro in Asia Monday as robust US data pointed to an ongoing economic recovery and worries persisted over Greece, analysts said. The euro, which shot as high as 1.34 dollars briefly in New York on Friday as debt-ridden Greece officially requested a rescue package from the European Union and International Monetary Fund, fell back in Asian trade Monday. The single European currency edged down to 1.3379 dollars in Tokyo afternoon trade from 1.3384 dollars in New York late Friday. The euro rose to 126.06 yen from 125.68 yen as higher stock prices prompted fund flows from the yen to riskier currencies, analysts said. Investors were 'not entirely heartened' by the weekend news on Greece, Mizuho Corporate Bank market analyst Daisuke Karakama said, noting the Greek debt problem is far from resolved. 'Greece's requesting aid is not a positive lead in itself. The point is whether the loan will be implemented smoothly or whether Greece can achieve fiscal rehabilitation,' he said. Nonetheless short-term investors bought the common currency amid growing speculation that Greece may soon receive financial support. The view means 'the euro is likely to get a bit of a break' this week from the recent selling, Hideaki Inoue, chief manager of forex and financial products trading at Mitsubishi UFJ Trust and Banking told Dow Jones Newswires. Athens has requested a 45-billion-euro (60-billion-dollar) rescue from the EU and IMF but is scrambling to get the package in place ahead of a May 19 deadline to pay bondholders more than eight billion euros, leaving only a small window to act or face a crippling default. Greece has seen its cost of borrowing soar as investors, fearing a default, have demanded greater risk premiums for their loans, which in turn has pushed the country's debt even higher. Its woes have hit the single currency hard, plunging the eurozone into the most serious crisis of its 11-year history and placing nations such as Portugal, Italy, Spain and Ireland in the firing line. The dollar hit a three-week high against the Japanese currency. The greenback rose to 94.37 yen briefly, the highest level since April 5, after coming back to 94.22 yen in the Tokyo afternoon against 93.97 yen in New York on Friday. 'Positive news from the US side, including strong homes sales, helped boost the dollar' as they confirmed the continuing strength of the US economic recovery, Karakama said. Sales of newly constructed single-family homes in the United States surged by nearly 27 percent in March compared with the previous month, official estimates showed Friday. The dollar fell against regional Asian currencies. The greenback sank to 31.30 Taiwan dollars from 31.34 on Friday, to 9,004 Indonesian rupiah from 9,010, and to 32.17 Thai baht from 32.26. It also slipped to 1,103.20 South Korean won from 1,108.60, to 1.3666 Singapore dollars from 1.3730 and to 44.19 Philippine pesos from 44.40.
