According to an NSE spokesperson, "The rationale of this decision is not based on numbers or what we will gain, this is more to take into account the fact that there are a lot of geopolitical developments over the weekend, and Monday is a great day to have the expiry. Of course we have been getting feedback since yesterday, but we have announced this decision keeping efficiency in mind. We will review if need be."

Further, there’s a chance of increased activity on Friday, as participants may prefer to square off positions rather than hold them over the weekend, as per experts. Further, they suggested that NSE's move is part of its efforts to gain back some of the market share in options market.
