RBI Governor Raghuram is widely expected to announce this year's fourth rate cut tomorrow and expectations for the same have further increased after the US Fed's status quo.
Expectations are also fuelled by retail inflation dropping to 3.66 per cent in August and economy expanding at a slower pace of 7 per cent during the same month.
Investors, meanwhile, were spooked by Europe, where shares were in deep red after mining major Glencore slumped to a record low on depressed commodity prices.
Consequently, the BSE metal index fell by more than 2.50 per cent. Besides, auto shares tumbled 1.74 per cent.
Moreover, mixed Asian markets after profits at China's major industrial companies saw their biggest declines in four years last month added to the subdued mood.
However, the barometer succumbed to profit-booking and slipped to a low of 25,593.56 before ending at 25,616.84, a loss of 246.66 points or 0.95 per cent.
This is index's weakest closing level since September 11 at 25,610.21.
On similar lines, the 50-share NSE Nifty dipped below the crucial 7,800-mark and settled down 72.80 points or 0.93 per cent at 7,795.70. It shuttled between 7,893.95 and 7,787.95.
Meanwhile, a data showed that foreign investors sold shares worth Rs 115.10 crore on Thursday. Markets remained closed on Friday for Eid.
