The read
BSE has reset the strike price intervals for stock options, a routine adjustment to keep options chains aligned with current stock prices and liquidity. The change, effective July 1, 2026, is per-scrip and detailed in an annexure. For most traders, the impact is mechanical: systems that generate or display strikes must be updated before the deadline. No market disruption is expected, but members who ignore the revision risk incorrect pricing or execution gaps. BSE has provided a contact window for clarifications.
