SEBI: ITM Single-Stock Options to Devolve into Futures One Day Before Expiry
2024-12-05
On November 18, the regulator took a significant step by passing directions against three specific platforms. This move comes as part of the Securities and Exchange Board of India (SEBI)'s continuous efforts to ensure the stability and integrity of the financial markets. In a consultation paper released on December 5, SEBI proposed a novel approach to manage potential risks associated with single stock derivatives. The proposed change aims to mitigate the impact of sudden price movements near market close on expiry day.
SEBI's Initiative to Transform Single Stock-Option Contracts
Current Scenario and Proposed Changes
Currently, all in-the-money (ITM) options based on the last 30 mins VWAP on the expiry day are auto exercised and converted to underlying deliverable obligations. However, SEBI now proposes that ITM options will initially devolve into stock futures one day prior to expiry, i.e., E-1 day. This means that instead of directly resulting in physical delivery obligation on expiry, the positions will first transform into futures. On the expiry day, only futures will be tradeable, and the open futures positions will be settled by delivery as at present.For example, assume that the stock future contracts expire on the last Thursday of the month. On Wednesday, which is one working day prior to the expiry (E-1 day), all the open positions in option strikes that are ITM based on the last 30 minutes VWAP of the underlying stock will be auto exercised and will devolve into a futures position at the exercise price, set to expire on Thursday. The resultant positions in futures can be closed on Thursday, and the residual open positions will be settled via delivery.This mechanism is comparable to what is available in the commodity derivative segment and is designed to minimize system-level changes at market-infrastructure institutions (MIIs), trading members, and clearing members.Impact on Option Positions
Upon exercise, option positions may devolve into futures in specific ways. Long ITM call positions may devolve into long positions in the underlying future contracts. Long ITM put positions may devolve into short positions in the underlying future contracts. Short ITM call positions may devolve into short positions in the underlying future contracts. And short ITM put positions may devolve into long positions in the underlying future contracts. All such devolved futures positions shall be opened at the strike price of the exercised options.This detailed approach ensures a clear and systematic transition of option positions to futures, providing market participants with a more predictable and manageable trading environment. It helps in reducing the potential risks associated with sudden price movements and physical settlement requirements, thereby enhancing the overall efficiency and stability of the single stock-option market.
