Indian Traders Face First Monthly Derivatives Expiry Under New System

Indian traders are preparing for the first monthly derivatives expiry under a new auction-based end-of-day stock price system. Launched on August 3, the mechanism seeks to align India with global market standards, but it has faced criticism for increasing price volatility and enabling potential manipulation.

The upcoming Tuesday expiry serves as a critical test for the system. Unlike previous cycles, this event involves a broader range of derivatives, including physically settled single-stock options. In these contracts, sharp price swings during the auction period can suddenly trigger delivery obligations for funds or shares, increasing risk for participants.

Market adoption has been uneven, with low participation from proprietary firms and high-frequency traders resulting in thinner trading volumes. The Securities and Exchange Board of India has already taken enforcement action, barring two firms—including a unit of JPMorgan Chase & Co.—for allegedly manipulating prices during the auction process. To mitigate risks associated with the expiry, the regulator has extended derivatives trading hours.
