The Shikha Sharma-led bank had posted a post-tax profit of Rs 1,915.64 crore in the July-September period last year.
Total Income increased to Rs 13,698.7 crore in the period under review from Rs 12,001 crore for the quarter ended September 30, 2015.
Warning of further pain in the future, its chief financial officer Jairam Sridharan told reporters that the pain was primarily on account of a larger proportion of the assets placed under a 'watch-list' slipping into the NPA category.
"We now believe that slippage from the 'watch-list' may be higher than the 60 per cent we had originally envisaged," Sridharan told reporters on a conference call after the announcement of the results post market hours.

"A materially higher proportion of the 'watch-list' could turn NPA by the end of FY18. We are watching the operating environment closely, and are looking for some of the resolution mechanisms in the market to kick in," he added.
The bank, which had given a credit cost guidance of up to 1.50 per cent for the full year, has already witnessed the credit cost going up to 3.05 per cent on an annualised basis and Sridharan conceded that it will have to review the guidance.
The spike in the NPAs also resulted in the provision coverage ratio slipping to 60 per cent from 69 per cent in June and Sridharan informed reporters that the bank will strive to increase the same.
Meanwhile, on the asset quality resolution front, the bank
today reported its first exit out of its 'watch list', with two "fairly small" accounts being repaid in full, Sridharan said, declining to give an indication of the outstanding accounts under the category.
The loan recoveries and upgradations were at Rs 1,073 crore during the reporting period, while loans worth Rs 873 crore were written off.
The bank's advances rose 18.5 per cent, driven largely by retail loans which expanded at 25 per cent to grow its share to 42 per cent of the book. Corporate advances rose 14 per cent, the same as loans to small and medium advances.
The core net interest income rose 11 per cent to Rs 4,514 crore rupees, while net interest margin dropped to 3.64 per cent from 3.79 per cent in the preceding quarter and last year's 3.85 per cent.
Sridharan said the cost-to-income ratio for the quarter was 42 per cent, and is seen at around 40 per cent for the fiscal, Sridharan said.
Shares of the bank gained 1.49 per cent on the BSE to close at Rs 529.05 apiece.
