SINGAPORE, June 4 (Reuters) - The dollar held onto big overnight gains on Wednesday and oil prices remained down, giving some support to Asian stocks and helping them recover from fresh concerns over the impact of the credit crunch.
The dollar jumped against the euro and other major currencies on Tuesday after Federal Reserve Chairman Ben Bernanke gave an unusually explicit warning about the inflationary threat from a weak U.S. currency. [
]Analysts said the comments suggested the Fed was unlikely to cut interest rates further from 2 percent, and may look to hike borrowing costs later this year.
"It was extraordinary for the Fed to make a specific comment on the dollar, even in the context of inflationary risks," said Toshihiko Sakai, a manager of forex trading at Mitsubishi UFJ Trust Bank in Tokyo.
The dollar generally held steady in early trade on Wednesday, trading around 105.13 yen <JPY=> and $1.5458 to the euro <EUR=>.
The stronger dollar helped push down the price of oil and other commodities. U.S. crude <CLc1> was flat on Wednesday at $124.36 a barrel after having fallen more than $3 the day before. Spot gold <XAU=> fell to around $880.00/881.20 an ounce from $882.90/884.10 in late New York trade on Tuesday.
The dollar's longer-term weakness has helped drive commodity prices to record highs by encouraging the purchase of dollar-denominated commodities as a hedge against inflation.
Shares rose in the face of continuing jitters over the vulnerability of the financial sector to the credit crunch, set off earlier this week when a ratings agency downgraded three U.S. brokerages and as the Wall Street Journal reported that Lehman Brothers <LEH.N> may need to raise more capital.

Bernanke's comments brought into focus expectations that the Fed will stop in its cycle of lowering interest rates, helping send U.S. Treasuries down on Wednesday.
The yield on the 10-year note <US10YT=RR>, which moves in the opposite direction to the price, rose to 3.923 percent, up 3 basis points from late New York trade.
Japanese government bond futures fell after matching their biggest daily gain in five years on Tuesday, as investors took profits on the sharp rise.
June 10-year JGB futures <2JGBv1> fell 0.65 point to 134.70, after Tuesday's 1.43 point rise. The benchmark 10-year yield <JP10YT=RR> rose 4 basis points to 1.780 percent, after falling sharply the day before.
"There is no new factor to change the big picture as long as expectations for a recovery in the U.S. economy remain. JGB yields will likely stay near the upper end of the recent range," said Yasuhiro Onakado, chief economist at Daiwa SB Investments.
