Options Clearing Corporation (OCC)

Central clearinghouse guaranteeing all US options

What is Options Clearing Corporation (OCC)?

Options Clearing Corporation (OCC) The Options Clearing Corporation (OCC) is the central counterparty clearinghouse for all listed options and futures trades on U.S. exchanges. Founded in 1973, the OCC guarantees the performance of every options contract, effectively eliminating counterparty risk for exchange-traded options. It is the largest equity derivatives clearing organization in the world, clearing billions of contracts annually across multiple exchanges including CBOE, NYSE Arca, Nasdaq, and others. How it works: When a buyer and seller agree on an options trade, the OCC steps in as the counterparty to both sides. The buyer's contract is with the OCC (not the original seller), and the seller's obligation is to the OCC (not the original buyer). This intermediation means that even if one party defaults, the other is protected. The OCC maintains a clearing fund, collects margin from clearing members, and uses a multi-layered default waterfall to ensure obligations are met. It also handles the exercise and assignment process, randomly selecting short option holders for assignment when long holders exercise. For example, when you sell 10 contracts of the AAPL $200 call, you are not directly obligated to a specific buyer. Instead, the OCC guarantees your obligation. If you are assigned because a call holder exercises, the OCC manages the share delivery and cash settlement. If a counterparty broker fails, the OCC uses clearing member deposits and its own capital reserves to ensure the assigned party receives their shares or cash without disruption. The OCC's guarantee is what makes exchange-traded options fundamentally different from over-the-counter (OTC) derivatives, where counterparty risk must be assessed for every trade. Designated as a systemically important financial market utility (SIFMU) by the Financial Stability Oversight Council, the OCC maintains substantial financial resources and undergoes rigorous stress testing. Its role is largely invisible to retail traders, but it is the foundation that makes the entire listed options market possible.
