HONG KONG, March 20 (Reuters) - Gold, other metals and commodities fell sharply on Thursday as doubts about the global economy seeped into asset classes that hit record highs earlier this week. Asian shares slid on renewed credit crisis fears.
Bonds in Asia gained, as risk aversion returned to the region a day after investors cheered hefty U.S. interest rate cuts and resilient results from leading U.S. investment banks.
The dollar was mixed in choppy trade, as hopes of averting a slowdown in the United States, the world's largest economy, appeared dashed, though volumes were reduced as markets in Japan were closed for a public holiday.
"We're seeing a return to reality with regard to the situation in the U.S.," said Savanth Sebastian, equities economist at CommSec in Australia. "The trend in the U.S. remains the same, credit markets remain tight and possible writedowns can continue."
The MSCI's measure of Asian stocks outside Japan <.MIAPJ0000PUS> fell 2.5 percent by 0212 GMT. The index dropped to its lowest since August earlier this week before rebounding on Wednesday.
Shares in Australia <

]Asian stocks have had a volatile week that started with worries about more casualties following the fire sale of Bear Stearns <BSC.N> to JPMorgan & Chase <JPM.N>.
But markets perked up mid-week following the U.S. Federal Reserve's rate cut and not-as-bad-as-expected results from Goldman Sachs <GS.N> and Lehman Brothers <LEH.N>
GOLD SLUMPS
Metals extended a sharp fall from the previous session amid concerns that a U.S.-led economic slowdown could undermine global demand.
Analysts saw a shift to U.S. Treasuries after a U.S. government regulator cleared the way for the country's housing finance agencies Fannie Mae and Freddie Mac to pump up to $200 billion into the distressed U.S. mortgage market. [
]"Commodities was the one area that had been untouched by the credit chaos, but that seems to be changing," said Robert Rennie, chief currency strategist at Westpac in Australia.
Gold tumbled more than 2 percent in Asian trade to its lowest level in more than a month as funds cashed in after pushing the metal to a record $1,030.80 an ounce on Monday.
Bullion <XAU=> was last traded near $930 after hitting a session low of $922.90, the lowest since Feb. 20.
Metals from platinum to silver had been routed a day earlier, with gold falling 6 percent on Wednesday in its biggest one-day percentage drop in nearly two years. The falls spread to commodities, with the Reuters-Jefferies CRB Index <.CRB> hitting a 1-month low on Wednesday.
U.S. crude futures also fell after slumping in the previous session. U.S. crude for May delivery <.CLc1> was off 57 cents at $101.97 a barrel. The April contract hit a record $118.80 on Monday.
The dollar was pinned at 98.90 yen <JPY=>, little changed from New York's close and well off Wednesday's high of 100.44. The U.S. currency was trading at $1.5584 per euro compared with $1.5608 in late U.S. trade.
The global market uncertainty lifted some Asian bonds, with Australia's three-year contract <YTTc1> up 0.105 to 93.98, and the 10-year contract <YTCc1> up 0.115 to 94.035.
