India’s benchmark stock index rose to a record for a sixth day as international investors extended Asia’s largest equity-market inflows.

Bharti Airtel Ltd. (BHARTI) rallied to the highest level since Jan. 15 amid a report that the nation’s largest carrier plans a $ 2 billion bond sale to lower debt costs. Wockhardt Ltd. (WPL) surged by the daily limit amid speculation the U.S. regulator may ease an import ban on Indian drugs. Tata Motors Ltd. (TTMT), owner of Jaguar Land Rover, advanced to a one-month high.

The S&P BSE Sensex (SENSEX) added 0.5 percent to 22,514.90 at the close. The gauge climbed 5.5 percent in the previous quarter, beating stocks in Brazil, Russia and China, as easing inflation and forecasts for a change in government after polls starting next week lure inflows. Foreigners bought a combined $ 222.9 million of shares on April 1 and March 31, according to data from exchanges. That adds to inflows of $ 3.6 billion into local equities this year through March 27.

“Relentless buying by foreign investors is lifting market sentiment,” said Gajendra Nagpal, executive officer at Augment Financial Services Pvt. in New Delhi. “The pre-election rally is getting a boost from moderating inflation and the deficits getting under control.”

The Reserve Bank of India yesterday kept the benchmark rate at 8 percent as retail inflation eased to a two-year low and the government forecast smaller budget and current-account shortfalls. The rupee strengthened to an eight-month high. The currency had its biggest quarterly gain since September 2013, rallying 3.2 percent to 59.89 on March 28.
