The BSE Sensex fell for a second day on Wednesday, with ICICI Bank, HDFC Bank and SBI among the losers on mounting concerns about asset quality.

The banking sector is bringing down the market today as there are concerns regarding NPAs and high interest rates, said R.K. Gupta, managing director at Taurus Mutual Fund.

Non-performing assets, or bad loans, are expected to rise to about 2.6 percent of the total assets of Indian banks in the fiscal year ending March from 2.3 percent a year ago, ratings agency Crisil said earlier this year.

Borrowers are facing difficulty to repay loans due to a slowing economy and high interest costs.

At 10:35 a.m. (0505 GMT), the main 30-share BSE index .BSESN was down 0.64 percent at 15,771.47, with 24 of its components in the red.

The market is likely to be quiet volatile today as the volumes are quiet low, Gupta said.

He said the index could swing in a wide band of 300-400 points, with the expiry of monthly derivatives contracts on the National Stock Exchange on Thursday adding to the volatility.

ICICI shed 2 percent, HDFC Bank dropped 0.8 percent and State Bank fell 1.4 percent.

Tata Power (TTPW.NS) bucked the trend and climbed as much as 4 percent after the utility said it would buy BP Alternative Energy Holding's 51 percent stake in joint venture Tata BP Solar for an undisclosed amount.

Adani Power (ADAN.NS) fell as much as 5.7 percent, a day after its chief executive said the company put on hold its plans for capacity expansion of 6,500 megawatts because of a lack of clarity on coal supplies.

The 50-share NSE index was down 0.8 percent at 4,712.50. In the broader market, there were about two losers for every gainer, on relatively lighter volume of 107 million shares.

Asian shares were subdued on thin trade, while oil kept gains from the previous day on concerns about possible supply disruptions after Iran threatened to stop the flow of oil from the Gulf.

The MSCI's broadest index of Asia Pacific shares outside Japan was down 0.95 percent.
