The National Stock Exchange (NSE) on May 18, 2026, issued a Corrigendum on Introduction of Interest Rate Derivatives Contracts in GOI Securities.
The following has been stated:
NSE, through a corrigendum to its earlier circular dated May 15, 2026, has announced updated Interest Rate Futures and Options contracts on Government of India (GOI) securities, which will be available for trading from May 19, 2026. The newly introduced contracts include symbols 636GS2031 with a 6.36% coupon maturing on February 16, 2031, and 694GS2036 with a 6.94% coupon maturing on May 11, 2036. The exclusion dates for these contracts are January 2027 for 636GS2031 and April 2028 for 694GS2036.
The Exchange has also specified the monthly and quarterly expiry schedules, along with spread contract expiries for the introduced instruments. However, the March 25, 2027, quarterly expiry contract will not apply to symbol 636GS2031. The lot size for these contracts has been fixed at ₹2 lakh face value of GOI securities, equivalent to 2000 units, and members are required to place orders in terms of lots. Additionally, the quantity freeze limit has been set at 1250 lots, meaning orders above 1250 lots will not be permitted. All other provisions of the earlier circular dated May 15, 2026, remain unchanged.
