Interest Rate Futures are standardised exchange-traded derivative contracts whose value is derived from the price or yield of an underlying interest rate instrument — typically a government bond or treasury bill. In India, NSE and BSE offer interest rate futures on 91-day Treasury Bills, 2-year Government Securities, 5-year Government Securities, and 10-year Government Securities (the most actively traded). These contracts allow participants to hedge against interest rate risk — banks, primary dealers, insurance companies, and mutual funds use interest rate futures to protect their fixed income portfolios against adverse yield movements. For example, a mutual fund holding a large position in 10-year G-Secs can short 10-year government bond futures to offset the mark-to-market impact of rising yields. Speculators and macro traders use interest rate futures to express views on RBI monetary policy — buying futures when expecting rate cuts (which push bond prices up) and selling when expecting rate hikes. RBI policy announcements are the most significant event-driven catalyst for Indian interest rate futures markets.
