NEW YORK, June 3 (Reuters) - The dollar rose broadly and government debt, gold and oil prices dropped on Tuesday after Federal Reserve Chairman Ben Bernanke issued a rare warning about the inflationary risk of a weak U.S. currency.
U.S. and European stocks gained moderately as investors saw the decline in oil to below $126 a barrel as beneficial to the economy. Equities also drew strength from data showing a surprise rise in new orders at American factories in April, easing concerns over the health of the U.S. economy.
The dollar extended gains against major currencies after the U.S. factory data showed new orders, which economists had expected to fall, rose a more-than-expected 1.1 percent,
But the real market mover was Bernanke's highly unusual comments on the battered dollar. Federal Reserve officials usually defer to the U.S. Treasury on the dollar's value.
The euro fell to nearly a three-week low versus the dollar at $1.5432 as Bernanke said the Fed and Treasury were carefully monitoring currency markets, suggesting growing concern among U.S. officials about the dollar's slide and its inflation link.
"Bernanke seems more concerned about inflation than growth and for the first time that I remember he brings the weak dollar into the macro picture by linking rising import costs -- inflationary -- to the front page," said Tom Sowanick, chief investment officer at Clearbrook Financial LLC in Princeton, New Jersey.
A factor driving commodity markets this year has been the U.S. currency's weakness, which encourages the buying of dollar-denominated commodities as an inflation hedge.
Bernanke, who spoke in Washington via satellite to a conference on monetary policy in Barcelona, also indicated the Fed's interest rate cutting campaign was at an end, which tempered demand for safe-haven U.S. government debt.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 6/32 to yield 3.99 percent. The 30-year U.S. Treasury bond<US30YT=RR> fell 8/32 to yield at 4.69 percent.

Against the yen, the dollar <JPY=> rose 0.73 percent at 105.22.
"Bernanke is still leaving the impression that he's done easing," said Rick Klingman, managing director of Treasury trading at BNP Paribas in New York.
European stocks trimmed some of the previous session's losses to end higher as Royal Bank of Scotland <RBS.L> and UBS <UBS.VX> recovered.

UBS gained 3.8 percent, rebounding from recent losses, helped by comments from rating agency Standard & Poor's.
Despite their rally, other banks suffered fresh losses on worries about the credit crisis.
"Investors are concerned that the European housing market bubble could burst. House prices have come down in the U.S., but they are just starting to fall in Europe," said Francois Chevallier, strategist at VP Finance in Paris.
