The U.S. dollar was higher against the yen and the euro in Asian trading early Tuesday amid renewed speculation about a possible Chinese revaluation. The dollar was trading at 105.75 yen, up 0.11 yen from late Monday in Tokyo. The euro fell to US$1.2990 Tuesday morning from US$1.3020 late Monday and to 137.40 yen from 137.62 yen. The dollar touched a fresh one-month low versus the yen of 106.06 yen in overseas trading overnight and the euro hit a two-month low versus the Japanese currency. The gains come after comments over the weekend from People's Bank of China Governor Zhou Xiaochuan and Deputy Director of the State Administration of Foreign Exchange Wei Benhua. Some investors interpreted the remarks as signaling that China might be less resistant to a change in the yuan's de facto peg to the dollar. However, neither Zhou nor Wei gave any real indication China was knuckling under to U.S. pressure for imminent change in the country's foreign-exchange system. Both defended China's gradual approach to currency reform and didn't state a timeframe for any additional measures. Asian currencies have also been getting a lift from expectations that China may revalue its yuan this year -- a move that is expected to push Asian currencies higher.
