Options Clearing Corporation (OCC): The Clearinghouse Behind Listed Options

Learn what the OCC does, how it clears listed options, and why central

On this page

The Options Clearing Corporation (OCC) is the central clearinghouse for listed U.S. options and certain related products.

It stands between buyers and sellers after a trade is executed, which means the original two trading parties no longer rely directly on each other for performance.

What the OCC Does

The OCC helps the listed-options market function by:

  • clearing and settling contracts
  • managing margin and collateral requirements
  • guaranteeing contract performance subject to its rules
  • processing assignment and exercise activity

This central role reduces bilateral counterparty risk and makes the options market more scalable and orderly.

Why It Matters

Without a strong clearing structure, listed options would be far harder to trade at scale. The OCC gives the market a common operational and risk-management backbone.

That does not remove market risk for traders, but it greatly improves settlement integrity and systemic confidence.
