NEW YORK, May 11 (Reuters) - A slide in oil prices on Wednesday sparked a second big rout across commodities in less than a week, driving investors away from riskier investments like stocks.

Crude oil prices tumbled by more than 3 percent, driving New York crude below $100 a barrel, stung by a rise in crude oil inventories and signs that China's economy is cooling.

Other commodities also slumped, with spot silver down more than 7 percent. The Reuters-Jefferies CRB index <.CRB>, a global benchmark for commodities prices, dropped 2.6 percent.

On Wall Street, all three major indexes fell more than 1 percent, led by losses in energy shares, while the dollar and U.S. Treasuries gained on a safe-haven bid.

Heightened worries about debt-stricken European countries drove down the euro, which hit a three-week low against the dollar.

"With the dollar continuing to strengthen, commodities like oil should continue to trade off given the inverse relationship between the dollar and some of these commodities," said Phil Orlando, chief equity market strategist, at Federated Investors in New York.

"All these different issues -- currencies, the commodities, equity prices, the risk trade -- all seems to be somewhat interrelated."

Brent crude was down $3.96 at $113.67 a barrel, while U.S. crude futures tumbled 4.37 percent to $99.32.

The Dow Jones industrial average <.DJI> was down 150.95 points, or 1.18 percent, at 12,679.57. The Standard & Poor's 500 Index <.SPX> dropped 16.32 points, or 1.2 percent, to 1,340.84. The Nasdaq Composite Index <.IXIC> gave up 30.17 points, or 1.05 percent, at 2,841.72.

The market's decline was broad, with six stocks falling for every one rising on the New York Stock Exchange.

Oil related exchange traded funds fell sharply.

The U.S. oil fund LP fell 4 percent to $39.46, the Energy Select Sector SPDR Fund was off 3.2 percent at $74 and the U.S. gasoline fund LP was down 7.5 percent at $50.82.

DEBT WORRIES DOG EURO

New outbreaks of unrest in Europe highlighted the worries over debt-laden peripheral nations.

The euro hit a session low of $1.4275 on the EBS trading platform. It was last at $1.4288, about 0.8 percent lower on the day, but within its range of the past few days.

The European peripheral nations "have never had their fiscal house in order," said John Doyle, strategist at Tempus Consulting in Washington. Investors "may have lost focus on that but it is now back in focus."
