The total amount raised by firms via corporate bonds in the first half of this fiscal year (FY) was Rs 4.98 lakh crore, up 6 per cent YOY. Only Rs 4.7 lakh crore was raised during the corresponding period last year, as per data from market research firm Prime Database. Reportedly, the growth can be attributed primarily to more institutions tapping the bond market primarily because of lower yields. Further firms and investors feel they need to diversify their borrowings and hence higher high domestic demand.
