F&O Expiry: BSE Shifts Expiration Days For Sensex, Other Derivative Contracts To Tuesday

BSE Ltd. said on Thursday that it will revise the expiration days for the Sensex, Bankex, and Sensex 50 index derivative contracts, effective Jan. 1, 2025.

The weekly Sensex derivative contract will now expire on Tuesday of each week, replacing the current schedule of Friday. The monthly contract for the benchmark index will follow the same change.

In the monthly segment, the Bankex contract will now expire on the last Tuesday of the expiration month, instead of Monday. For the Sensex 50, the contract expiration will shift from the last Thursday of the expiration month to Tuesday.

Additionally, for quarterly and semi-annual contracts of Sensex, the expiration date will move to the last Tuesday of the expiration month, rather than Friday.

The revisions come after BSE discontinued weekly index derivatives contracts on Sensex 50 and Bankex earlier this month to abide by new rules launched by the Securities and Exchange Board of India.

The SEBI had asked stock exchanges to limit weekly option contracts to one per exchange from Nov. 20, as part of broader measures aimed to curb frenzy in the F&O segment.

BSE stated that the expiration dates for existing index futures and options contracts will be updated as outlined above at the end of the trading day on Dec. 31.

The stock exchange also shared an illustration of weekly and monthly expiry contracts (table given below) with Tuesday as expiry day for contracts expiring in January 2025. Similar revision will be done in all forthcoming expiries thereafter.

The bourse clarified that there will be no change in existing weekly derivatives contract of Sensex expiring on Jan. 03, 2025.

New index derivatives contracts generated after Jan. 01, 2025, will have expiry day as Tuesday, BSE said.
