Trading in certain Sensex options contracts on the Bombay Stock Exchange (BSE) experienced brief interruptions on Thursday, September 10, 2026, just hours before their scheduled settlement. The incident led to temporary halts in activity for specific call options.
Retail brokerage Zerodha Broking was among the first to report the issues, flagging problems with price updates and order placements for some BSE contracts across various brokers via a post on X (formerly Twitter). Zerodha later confirmed that the problem had been resolved.
Exchange data revealed that the 75,000 and 76,200 strike call options on the Sensex, both set to expire on the same day, were simultaneously halted twice. These halts lasted for periods of 18 minutes and 11 minutes respectively, creating uncertainty for traders.
BSE Confirms Outage and Resolution
In response to the disruption, BSE issued its own statement on X, acknowledging an outage. "BSE experienced outage for a brief period from 9:42 am, affecting one of the partitions in the cash segment affecting the scrips that are mapped to it, while all other partitions operated normally," the exchange stated. "The issue was resolved, and normal operations resumed at 10:08 a.m."
The swift resolution by BSE helped prevent prolonged market disruption, though the brief glitches underscored the critical nature of seamless trading infrastructure, especially during settlement periods.
