NEW YORK (Reuters) - Global stocks rallied on Monday, backed by a rise in oil and commodity prices, while the British pound suffered its biggest one-day loss in nearly six years against the dollar on fears Britain would leave the European Union.
Sterling tumbled to a near seven-year low during the session after popular London Mayor Boris Johnson said he would campaign to leave the EU ahead of a June 23 referendum. The euro also endured its biggest single-session decline since November.[nL8N1611DK]
Battered oil prices jumped as speculation about falling U.S. shale output helped feed the notion that crude prices may be bottoming after their 20-month collapse.
Benchmark Brent settled up 5.1 percent to $34.69 a barrel, while U.S. crude settled up 6.2 percent at $31.48 a barrel.
Stocks, whose performance has been tightly linked to oil prices as the commodity's slide has deepened, posted solid gains across major markets.
"Driving everything has been the recovery in energy and commodity prices," said Rick Meckler, president of LibertyView Capital Management in Jersey City, New Jersey. "That has been the part of the market that investors have been most concerned with so seeing a rally, particularly in oil, has been taken positively."
The Dow Jones industrial average was rising 213.4 points, or 1.3 percent, at 16,605.39, the S&P 500 was gaining 23.72 points, or 1.24 percent, at 1,941.5 and the Nasdaq Composite was adding 60.49 points, or 1.34 percent, at 4,564.92.
All 10 major S&P sectors were higher, led by a 2 percent increase for the energy sector.
The gains built on last week's strong performance after a poor overall start for U.S. equities in 2016.
"The fact that we held it on Friday and then went through a weekend and sustained and advanced it even more, I think is building optimism and maybe we've turned a corner," said Jim Paulsen, chief investment officer at Wells Capital Management in Minneapolis.
The pan-European FTSEurofirst 300 share index rose 1.7 percent. Mining stocks were among the best performers, with Anglo American rising 10.8 percent, as the price of copper reached a two-week high.
Helped by mining shares, Britain's FTSE 100 index <.FTSE> rose 1.5 percent, despite concerns over a possible EU exit.
Stocks shrugged off a survey showing private sector business activity in the euro zone increased at its weakest pace in more than a year in February.
MSCI's index of world shares rose 1.2 percent.
Worries about a possible British exit from the EU sent the euro down 1 percent against the dollar. Sterling fell 1.8 percent against the greenback and dropped as low as $1.4057.
"A Brexit would be bad for sterling, but it would also be bad for the euro," said Neil Jones, Mizuho's head of hedge fund sales in London.
The dollar was up 0.8 percent against a basket of six currencies.
U.S. Treasury yields rose as rising stock and oil prices reduced demand for safe haven debt, ahead of an expected government sale of $88 billion in new short- and intermediate-dated debt this week.
Benchmark 10-year Treasuries were last down 5/32 in price to yield 1.7639 percent.
Zinc prices surged to a four-month peak and other base metals also gained as investors' appetite for risk increased while they also worried about potential shortages.
Gold fell 1.6 percent as the dollar strengthened and investor appetite for risk increased.
