IRF contract based on 8.27 per cent central government security maturing on June 9, 2020, while another IRF contract based on 7.88 per cent government bond maturing on March 19, 2030, will be made available for trading from July 31 this year, the exchanges said in separate circulars.
An IRF contract is "an agreement to buy or sell a debt instrument at a specified future date at a price that is fixed on Thursday."
The IRF market gets participation from retail investors, trading houses, FIIs and other institutions.
The exchanges, in May, had introduced an IRF contract with the newly launched 10-year government bond maturing in 2025 as its underlying.
