NEW YORK, June 29 (Reuters) - Crude oil prices gained more than 3 percent on Monday after news of fresh rebel attacks on installations in Nigeria, while global stocks rallied on renewed hopes of economic recovery and rising energy shares.
The U.S. dollar fell against the euro and the yen weakened as both the rise in oil prices and U.S. stocks reduced the safe-haven demand for the two currencies.
U.S. Treasury prices extended last week's rally, meanwhile, as investors squared away positions and tried to improve their holdings before the month and second quarter end on Tuesday to try to improve their holdings.
Benchmark yields on U.S. Treasuries slipped to their lowest in a month as prices for government debt on both sides of the Atlantic rose on continued relief over the strong demand for the recent heavy slug of new debt that has been sold.
Copper rose to a two-week high as investors bet the worst of the economic downturn had passed,
"Commodities are really the big story of the day. We've had the Nigerian oil field attack, which has seen oil spike and that's really driven up the stock market," said Dan Cook, market analyst at IG Markets in Chicago.
"With stocks up, investors are selling the dollar against the euro especially. The yen is also down sharply with equities trading higher."
The rise in crude oil also bolstered both U.S. and European energy shares. Exxon Mobil Corp <XOM.N> rose 2.2 percent, Royal Dutch Shell <RDSa.L> added 1.8 percent and Total <TOTF.PA> gained 2.5 percent.
