FCCB stands for Foreign Currency Convertible Bond, which is a bond issued by a country in a foreign currency. It acts as both a debt and equity instrument as the bondholder has the option to convert the bond into the company's equity shares. Many Indian companies issued FCCBs from 2004 to 2007 but are now struggling as the equity markets are lower than expected and most bonds have not been converted. Companies need to repay an estimated Rs. 33,000 crore but may seek to restructure terms, reset conversion prices, or utilize unused portions to emerge from the current crisis over maturing FCCBs.
