HONG KONG, April 9 (Reuters) - Asian stocks were flat and the dollar stayed weak on Wednesday as worries resurfaced about the U.S. economy and a global financial crisis, but some shares gained on reports of potential deals such as Chinese interest in a stake in BHP Billiton, the world's biggest mining company.
A week-long rally in Asian shares is seen under threat by some analysts, after U.S. savings and loans firm Washington Mutual Inc <WM.N> warned on Tuesday of a large quarterly loss, while Federal Reserve minutes revived fears of a recession in the U.S. economy.
The dollar remained weak on concerns about the U.S. economy, slightly pushing up oil and gold prices given that a falling U.S. currency makes the commodities more attractively priced for buyers in other currencies.
"This has been a bit of a reality check, with recent gains based entirely on hopes that the worst of the subprime crisis was over," said Koichi Ogawa, chief portfolio manager at Daiwa SB Investments in Japan.
The MSCI measure of Asian stocks outside Japan <.MIAPJ0000PUS> was up 0.7 percent by 0220 GMT.
Asian shares had staged a promising start to the second quarter, with the MSCI index hitting a one-month high on Monday, though few see an end to the uncertainty about a U.S.-led slowdown in the global economy and the financial crisis that triggered steep losses in January-March.
Those concerns were reinforced on Wednesday following Washington Mutual's quarterly loss warning and after minutes from the Fed's most recent meeting showed concerns about a nasty slide in the U.S. economy at a time of rising inflation. [
