A major explosion and fire broke out on Monday night, 02 Nov 2026, at Hindustan Petroleum Corporation’s refinery in Visakhapatnam, Andhra Pradesh. Officials said the incident occurred at the facility’s Residue Upgradation Facility, or RUF, sending flames and thick smoke over the surrounding area. Fire tenders and response teams were deployed, while authorities said no casualties had been reported and that the smoke was unlikely to be hazardous. 🔥
The immediate market question is whether the incident affected refining throughput, product dispatches or the operating status of the RUF. The cause remained unclear in the reported coverage, and officials had not indicated the extent of equipment damage or any expected shutdown period. Any confirmed interruption could have implications for refinery utilisation and regional fuel supply, while a quick containment update would help narrow the operational impact on the energy sector ⚡.
OI Charts data showed the company’s shares closed at ₹348 on 02 Nov 2026, up 2.19%, with volume of 5,157,546 shares. The stock had gained 2.2% over one session and 1.3% over five sessions, but remained down 0.3% over 20 sessions. It traded between a 52-week low of ₹316.20 recorded on 23 Mar 2026 and a high of ₹508.45 on 05 Jan 2026.
In derivatives, futures open interest rose 2.4% to indicate a long build-up, while the futures premium stood at 0.52%. The put-call ratio was 1.07, and the 23 Nov 2026 expiry showed maximum pain at ₹350. Both the largest call and put open-interest concentrations were at ₹350, making the level a key reference for the next trading sessions. Futures long build-up alongside the day’s share-price gain showed that positions increased as the stock moved higher, although it did not establish the incident’s eventual operational effect.
Investors will watch for an official update on the fire’s containment, equipment damage, worker safety, refinery throughput and restart timeline. Further disclosures from the company, police or fire authorities will determine whether the event remains a contained facility incident or develops into a broader production concern. 🛢️
