Leading stock exchange BSE has said it will auction investment limits on Friday enabling foreign investors to purchase corporate bonds worth over Rs. 8,300 crore. The exchange said in a circular that live bidding session for allocation of debt investment limits will be conducted on BSE's ebidxchange platform from 1530 hrs to 1730 hrs, after the close of market hours. The debt auction quota gives overseas investors the right to invest in the debt up to the limit purchased. Earlier this month, corporate debt had attracted bids to the tune of Rs. 12,005 crore from foreign portfolio investors in an auction of investment limits for such securities.
