The Indian equity benchmarks fell for the second straight session on Tuesday dragged by losses in banking shares as they came under selling pressure a day after the government announced Rs. 1.1 lakh crore loan guarantee scheme for the Covid-affected sectors and an additional Rs. 1.5 lakh crore under the Emergency Credit Line Guarantee Scheme. The Sensex ended 186 points lower at 52,550 and Nifty 50 index declined 66 points to close at 15,748.
