Will NSE Tuesday and BSE Thursday expiries change trading behaviour for everyone

SEBI has set two expiry days for all equity derivatives and exchanges have aligned, with NSE moving expiries to Tuesday and BSE to Thursday, and this brings a single, simple calendar that reduces overlap and confusion for investors. So planning positions and hedges now follows a clearer weekly rhythm across markets.

On expiry day, moves tend to be sharp and spreads can widen, and margin use also tightens, so short options and leveraged trades can feel more stress. And with NSE getting Friday to Tuesday for time decay, and BSE getting Wednesday to Thursday, strategies need small but real tweaks to timing and risk.

For investors, this rule improves predictability and can help avoid unnecessary churn, and it nudges focus to preparation a day early and to holding extra liquidity on expiry sessions. So review positions the previous evening, use stop losses with care, and keep strategies simple if learning derivatives to manage costs and surprises.
