Mumbai: Sensex and Nifty traded lower during the afternoon session of the trade on Thursday over a sharp rise in crude oil prices and decline in financial stocks.
Brent crude futures on Thursday surpassed the $60-a-barrel mark.
Also, investors awaited Q3 corporate results, set to start on Thursday, and more clarity regarding US-China trade talks.
The weekly report released on Wednesday by the Energy Information Administration showed that US crude oil inventories decreased during last week, Anuj Gupta of Angel Brooking told IANS.
Gupta added that the rise in price was positive for crude as crude prices had seen volatility in recent months because of the imbalance demand-supply ratio.
He, however, added that crude price rise will have an adverse affect on the Indian rupee.
In addition, the supply cut by OPEC and other major oil producers came into affect from January 1.
Lately, excess US oil has pushed down prices.
