NEW YORK, June 22 (Reuters) - U.S. and European stocks fell sharply while oil prices skidded on Monday as questions about the strength of a global economic recovery, highlighted by a gloomy World Bank report, weighed on market sentiment.
The U.S. dollar rose against the euro on concerns over the euro zone's economic and fiscal outlook, while higher-yielding currencies slipped on worries about global growth prospects.
Copper tumbled 4 percent to a three-week low, weighed by demand worries, and gold hit its lowest level since mid-May as the stronger dollar helped weaken other commodity prices.
Longer-dated U.S. and euro zone government debt, meanwhile, rose as weak equity markets on both sides of the Atlantic enhanced the allure of safe-haven investments.
Oil dropped 4 percent to below $67 a barrel as the dollar and weaker equities outweighed concerns about attacks on the oil industry in top African exporter Nigeria.
The World Bank warned that prospects for the global economy remained "unusually uncertain" despite signs of improvement, and cut its 2009 growth forecasts for most economies to a contraction of 2.9 percent from 1.7 percent decline in March. [
]"People were becoming perhaps a bit too complacent that most of the difficulties with the financial crisis were behind us. I see some cautious forces here and there," said Luc Van Hecka, chief economist at KBC Securities.
Worries that a recovery could be tepid have wilted the optimism that drove the benchmark Standard & Poor's 500 Index <.SPX> up by as much as 40 percent from a 12-year low in March.
Major U.S. oil companies Exxon Mobil Corp <XOM.N> and Chevron Corp <CVX.N> were the biggest drags on the Dow as crude oil <CLc1> fell below $67 a barrel. Exxon fell 2.8 percent and Chevron 3 percent.
"While the worst might be over, it doesn't mean we're off to strong growth in any of the major economies globally," said Alan Lancz, president of Alan B. Lancz & Associates Inc in Toledo, Ohio.
Sounding a similar note to the World Bank's forecast, the head of the Organisation for Economic Development and Cooperation said major economies will contract through 2009.
"We see a very difficult 2009," Angel Gurria, head of the 30-nation group, told Reuters television in Paris. "Unemployment problems are going to continue to linger." [

The euro <EUR=> was down 0.60 percent at $1.3857 against the dollar.
Investors awaited the U.S. Federal Reserve's policy-setting Open Market Committee meeting on Tuesday and Wednesday when they expect the FOMC to express a slightly brighter economic view. They are also watching whether policymakers address a recent rise in Treasury debt yields.
"We're seeing the euro lower across the board and I think that's largely the result of the mixed Ifo data overnight (in Germany) as well as ongoing position squaring ahead of this week's FOMC meeting," said Omer Esiner, senior currency analyst at Travelex Global Business Payments in Washington.
The dollar was higher against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.62 percent at 80.834.
Against the yen, the dollar <JPY=> was off 0.32 percent at 95.95.
As equity markets fell, investors sought out less risky assets. Ten-year Bund yields <EU10YT=RR> fell to a month low of 3.439 percent, while the price of U.S. long bonds jumped a full point. Bonds yields and prices move in opposite directions.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was up 17/32 in price to yield 3.71 percent. The 2-year U.S. Treasury note <US2YT=RR> was up 4/32 in price to yield 1.14 percent.
Oil fell. Nigeria's main militant group said on Sunday it had attacked three oil installations belonging to Royal Dutch Shell <RDSa.L> in the Niger Delta, widening a month-old offensive against Africa's biggest energy industry.
U.S. light sweet crude oil <CLc1> fell $2.83 to $66.72 a barrel.

Other commodity prices also fell. Benchmark copper <MCU3> on the London Metal Exchange traded at $4,765 a tonne, down from $5,025 on Friday.
"There is disillusionment over the green shoots recovery and there is a feeling generally that prices have overrun fundamentals," said Robin Bhar, an analyst at Calyon.
