Why are corporate bond markets active with big companies like Reliance Industries, Aditya Birla Finance, Tata Finance and M&M active in the bond markets?

That is true that corporate bond sales trebled in April as banks lent to the bluest of Indian blue chips. This was after the RBI opened a special window that gave banks the access to more long term financing at lower costs via the special TLTRO window. There was a three-fold jump in bond sales at Rs.71,628 crore compared with Rs.23,738 crore in the corresponding period last year. Reliance Industries, L&T, L&T Finance, HDFC, Mahindra & Mahindra, M&M Finance, Aditya Birla Fin and Tata Capital were among the top rated borrowers. This was due to a combination of RBI’s TLTRO auctions and ample liquidity in the financial system.
