Expiry is the deadline. After expiry, the option can no longer be used under its original terms.

Buyer outcome

  • If the option expires unexercised, the buyer usually loses the premium and fees.
  • The buyer does not receive a settlement benefit unless exercise completed under the terms.
2

Writer outcome

  • The writer usually keeps the premium.
  • Inventory or collateral may unlock after expiry and release checks.

Timing reminder

  • Expiry does not always mean instant release.
  • Final checks, network steps, or beta review can take extra time.
