Indian stock-index futures gained after the rupee capped its biggest four-day gain in at least 40 years and oil prices declined.

SGX CNX Nifty Index futures for September delivery rose 0.2 percent to 5,921.5 at 9:53 a.m. in Singapore. The underlying CNX Nifty (NIFTY) Index climbed 3.8 percent to 5,896.75 yesterday, the biggest gain since May 2009. The S&P BSE Sensex jumped 3.8 percent. The Bank of New York Mellon India ADR Index of U.S.- traded shares increased 2.8 percent. The rupee gained 2.2 percent to 63.84 per dollar yesterday, while one-month rupee forwards added 0.4 percent to 64.42 today. Brent crude dropped 2.2 percent yesterday, the biggest loss since June 20.

The rupee rose 6.1 percent in the past four days, the biggest gain since at least 1973, as U.S. jobs data that fell short of estimates tempered concern the Federal Reserve will cut stimulus this month. Falling crude prices and a strengthening currency cut import costs for a nation that buys about 80 percent of its crude from overseas. Oil imports jumped 18 percent from a year earlier to $ 15.1 billion in August, according to data from the Trade Ministry yesterday.

“There is a sense of euphoria triggered by the rupee again and the drop in crude oil prices,” Gajendra Nagpal, chief executive officer at New Delhi-based Unicon Financial Intermediaries Ltd., said by phone.

The Sensex and the rupee have also surged in the past week after new Reserve Bank of India Governor Raghuram Rajan announced plans to boost the financial sector and support the rupee, which has dropped 16 percent this year.

They pulled $ 3.7 billion from local equities in the three months to Aug. 31 as capital fled emerging markets amid prospects of the Federal Reserve paring its record stimulus.
