It may be related to the fact that there are declines in regional currencies and perhaps foreign investors are continuing to withdraw funds from the region.” He also said negative data about new home sales in the US on Tuesday may have rattled investor nerves in Asia. “Perhaps Asian investors have concluded that when the outlook for the U.S. is not that good, the outlook is not that good for Asia either,” he said.Sentiment was also dented after Moody’s Investors Service downgraded Japan’s credit rating to Aa3 from Aa2, citing weak growth prospects for the world’s No. 3 economy, massive government debt and constant political uncertainty. The new rating is three notches below Moody’s top Aaa rating. The downgrade, which puts Moody’s rating in line with other major credit rating agencies, is the latest blow for Japan after its economy remained mired in recession in the second quarter due to tumbling factory production and exports following the March 11 earthquake and tsunami.Mining shares sank after prices for gold and some other metals slipped Tuesday.
