Aug 11 (Reuters) - Wall Street was set to open lower on Tuesday after China's surprise devaluation of the yuan increased unease about the health of the world's second-largest economy and pushed the dollar higher.
The yuan fell to its lowest against the dollar in almost three years following what the country's central bank described as a "one-off depreciation".
This made dollar-denominated commodities more costly for buyers using other currencies. Oil, copper, gold and grains fell after sharp gains on Monday.
"We are looking at a pullback right now. The news of the yuan raises suspicion regarding the economic growth outlook for China, that's taking its toll on the markets," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
At 8:31 a.m. ET (1231 GMT), Dow e-minis were down 144 points, or 0.82 percent, with 36,779 contracts changing hands.
S&P 500 e-minis were down 15.5 points, or 0.74 percent, with 250,486 contracts traded and Nasdaq 100 e-minis were down 22.75 points, or 0.5 percent, on volume of 36,749 contracts.
Brent crude was down 1.81 percent and U.S. crude fell 2.56 percent. Prices of commodities such as copper, aluminum, nickel, and zinc slid between 1.5 and 3.5 percent.
Cardillo, however, does not expect the market to completely give up Monday's gains. "(The devaluation) just means a step up in the currency wars."
U.S. stocks had climbed on Monday, giving the S&P 500 its biggest increase since May, buoyed by gains in commodity-related shares and optimism over Warren Buffett's deal to buy Precision Castparts.
