NEW YORK, June 9 (Reuters) - The U.S. dollar fell broadly on Tuesday and pushed up crude oil nearly 3 percent as investors questioned whether an improving economy warrants talk of higher U.S. interest rates this year after all.
A U.S. government report forecasting increased energy demand also drove up the price of crude.
U.S. copper futures rallied more than 5 percent, helped by the renewed weakness in the dollar, and U.S. gold futures rebounded from Monday to end higher.
Short-term costs to borrow dollars fell, meanwhile, on reduced concerns that the Federal Reserve might raise interest rates sooner than the market expects.
At one point the euro extended gains versus the dollar to trade above $1.41.
Joseph Trevisani, chief market strategist at FX Solutions in Saddle River, New Jersey, said investors who bought the dollar recently betting on higher borrowing costs were at risk.
"Interest rates are not going to go up in this country anytime soon," Trevisani said.
Rate-hike worries also retreated on news the government approved 10 of the largest U.S. banks to pay back $68 billion in federal bailout money. See [
]Michael Woolfolk, currency strategist at The Bank of New York-Mellon, said there was a "very trivial chance that the United States will see significant inflation in the next 12 months."
Oil settled at a seven-month high above $70 a barrel after the U.S. Energy Information Administration raised its forecast for 2009 world demand by 10,000 barrels per day from its May report amid signs of an economic recovery.
"The EIA data showing it has raised its world and U.S. oil demand forecast for the first time since September is a sign that things are stabilizing on the demand side," said Phil Flynn, analyst at Alaron Trading in Chicago.
U.S. crude <CLc1> settled up $1.92 at $70.01 a barrel, the highest settlement since Nov. 4. London Brent crude <LCOc1> gained $1.74 to settle at $69.62 a barrel.
