Bank shares were the top losers on concerns that NIMs would take a hit on recent cut in base rate.
Benchmark shares indices ended lower for the sixth straight session amid sell-off in late trades after the rupee hit a fresh 2-year low while growth concerns in China dampened investor sentiment.

"Further, growth concerns in China and fears of further devaluation of the yuan also aided the decline," said Jagannadham Thunuguntla, Head of Fundamental Research at Karvy Group.
The 30-share Sensex dropped 308 points to end below 25,000 at 24,894 and the 50-share Nifty slipped 96 points to end at fresh 13-month low of 7,559. In the broader markets, the BSE Mid-cap and Small-cap indices closed 1.8-2.2% lower.
