NEW YORK (Reuters) - Stock index futures were slightly higher on Wednesday, but gains were capped as concerns about the Chinese economy pressured commodity prices.
Chinese shares fell 3 percent, led lower by banks and property issues, after the government raised bank capital requirements in the clearest sign yet it has started to tighten monetary policy for the world's third largest an economy.
Investor concern about China dented commodity prices, as copper hit a two-week low and crude oil fell below $80 per barrel, threatening to weigh on shares of U.S. commodity and industrial companies.
"That is the biggest driver today. If we get any bounce (in commodity prices) we might be able to move forward. But without that, this market is going to be under pressure," said Arthur Hogan, chief market analyst at Jefferies & Co in New York.
S&P 500 futures rose 3 points but were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 10 points, and Nasdaq 100 futures added 3.75 points.
U.S. president Barack Obama is to announce plans on Thursday to raise up to $120 billion from major U.S. financial companies to cover expected losses from the taxpayer-funded bank bailout, according to a senior administration official.
