* Bank shares lifted after Basel III agreement
* China factory data boosts economic optimism
* Futures up: Dow 87 pts, S&P 9.6 pts, Nasdaq 14 pts
NEW YORK, Sept 13 (Reuters) - U.S. stock index futures rose on Monday after strong Chinese factory data and a deal on global bank rules that give lenders more time before they must raise additional capital.
* Global regulators agreed Sunday to force banks to more than triple the amount of top-quality capital they must hold in reserve in an effort to prevent another credit crisis. But the new rules, known as "Basel III", give lenders transition periods that could extend to January 2019 or later -- more time than many bankers expected.
* Bank shares boosted European markets, with the pan-European FTSEurofirst 300 gaining 0.8 percent. Among U.S. banks, Citigroup Inc was up 1 percent at $3.95 in premarket trade, while Bank of America rose 1.9 percent to $13.81.
* Chinese factories ramped up production in August, data showed, and money growth easily topped expectations, helping to give futures a positive tone. The data built on recent improved sentiment in U.S. markets as worries eased over whether the economy was headed back into recession.
* S&P 500 futures rose 9.6 points and were above 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 gained 87 points, and Nasdaq 100 futures added 14 points.
* A positive day for the S&P 500 and Dow would amount to a fourth dtraight session of gains. The broad S&P 500 has rallied nearly 6 percent since the end of August.
* British oil major BP Plc believes compensation claims related to its Gulf of Mexico oil spill will be less than the $20 billion it put into an independent claims fund, analysts at Citigroup said after meeting with incoming Chief Executive Bob Dudley. BP's U.S.-listed shares added 0.9 percent to $38.57.
* Car rental company Hertz Global Holdings Inc struck a sweetened $1.56 billion deal to buy Dollar Thrifty Automotive Group Inc on Sunday, outdoing a rival bid from Avis Budget Group Inc.
