Sensex Options Premium Turnover Surges 53% to Record ₹35,481 Crore in October as Crude Tops $102
Heightened market volatility across Indian benchmark equities drove Sensex options volumes on the BSE to an all-time high in October. A combination of escalating conflict in West Asia and triple-digit crude oil prices led to wide intraday gyrations, drawing active participation from retail and institutional derivatives traders seeking to hedge downside risks and trade index swings.
According to exchange data, the average daily premium turnover (ADPT) for Sensex options rose to a record ₹35,481 crore in October. This represents a 53% surge compared to ₹23,245 crore recorded in September. Concurrently, the National Stock Exchange (NSE) saw its index options average daily turnover climb to ₹63,227 crore, marking its highest level since March, when it touched ₹85,508 crore. During October, NSE retained a 64% market share in index options turnover, while BSE captured the remaining 36%.
Crude Oil Surge and Benchmark Gyrations
The primary catalyst for the surge in derivatives turnover was the sharp uptick in global energy prices. Crude oil jumped 4% over the period to $102.31 a barrel amid supply disruptions and geopolitical confrontations in West Asia. Because India imports over 85% of its crude oil requirements, triple-digit crude prices put immediate pressure on domestic inflation, the rupee, and corporate margins, prompting swift equity sell-offs.
Reacting to the spike in oil, the 30-share BSE Sensex dropped 1.6% from September 30 to touch a 52-week low of 71,292.88 on October 1. The index subsequently experienced a sharp rebound, swinging nearly 5% from that trough to register a monthly high of 74,849.75 on October 19. The index finished the final session of the month at 74,459.53.
The Nifty 50 witnessed similar instability, moving within a 4.5% band between its 52-week low of 22,179.90 on October 8 and a peak of 23,175.25 on October 19. The index ended the month at 23,053.10, remaining 12.6% below its 52-week peak of 26,373.20 touched in early January.
Weekly Expiry Framework Powers Volumes
Market participants noted that the volatility expansion coincided with high positioning around weekly contract settlements. Under the market structure established by the Securities and Exchange Board of India (SEBI)—which limits exchanges to one weekly benchmark expiry each—BSE's Sensex options expire on Thursdays, whereas NSE's Nifty contracts settle on Tuesdays.
Shai Coelho, founder of stock analysis firm Vtrender, highlighted that volatility played directly into trading activity: "The relatively higher volatility pushed up Sensex volumes to a record high and Nifty to multi-month highs, with the boost also coming on weekly settlement days, when index option volumes tend to be higher."
Key Data Highlights for October:
- Sensex Options ADPT: ₹35,481 crore, up 53% from ₹23,245 crore in September.

With crude oil hovering at elevated levels, domestic market participants are bracing for continued price discovery and elevated option premiums across upcoming weekly expiries.
