Why in the news

SEBI approved a reshuffle of weekly equity derivatives expiry days across the two exchanges.

ItemChange
NSETuesday (was Thursday)
BSEThursday (was Tuesday)
Effective1 September 2025
Existing contractsKeep expiries, except long-dated index options, which are realigned

SEBI’s rationale

  • Reduce hyperactivity and concentration risk on expiry days.
  • Stop frequent expiry changes; ensure product differentiation; two expiry days weekly, so exchanges choose separate days.

Likely impact

  • NSE: more liquid, may gain participation; premiums just before expiry may fall.
  • BSE: may cede 200-300 bps (Nuvama Research); shares fell over 10%.
  • BSE CEO Sundararaman Ramamurthy says Thursday is familiar to traders.

Exam angle

  • Effective date: September 1, 2025.
