Options Clearing Corporation (OCC) Explained
Learn how the Options Clearing Corporation guarantees every options trade in the US market. Understand the role of the OCC in settlement, risk management, and market stability.
What is Options Clearing Corporation (OCC)?
Options Clearing Corporation (OCC) is the world's largest equity derivatives clearing organization, acting as the central counterparty that guarantees performance of every listed options contract traded on US exchanges.
The OCC eliminates counterparty risk by stepping between buyers and sellers. When you buy an option, your counterparty is the OCC—not the individual trader who sold it. This guarantees settlement even if one party defaults.
TL;DR - Quick Answer
The OCC (Options Clearing Corporation) is the central counterparty for all US options trades. It guarantees every contract, manages settlement, handles assignments, and eliminates counterparty risk. When you buy/sell options, your counterparty is the OCC, not the other trader. OCC has never failed to settle a trade since its founding in 1973. It clears 7+ billion contracts annually.
What is the Options Clearing Corporation?
The Options Clearing Corporation (OCC) is the invisible backbone of the US options market. Founded in 1973 alongside the Chicago Board Options Exchange, the OCC acts as the central counterparty for every listed options and futures trade in the United States—clearing over 7 billion contracts annually.
When you buy an option on your broker's platform, you might think the person who sold it is your counterparty. They're not. The OCC steps between both parties, becoming the buyer to every seller and the seller to every buyer. This eliminates counterparty risk and ensures that every trade settles, even if one party can't fulfill their obligation.
How the OCC Works
Trade Clearing
After your broker executes an options trade on an exchange (CBOE, NYSE Arca, NASDAQ, etc.), the trade is submitted to the OCC for clearing. The OCC validates the trade, calculates margin requirements, and becomes the counterparty to both sides.
Settlement and Assignment
When options expire or are exercised, the OCC manages the settlement process. For exercise and assignment, the OCC randomly allocates assignments to clearing members (brokers), who then allocate to individual accounts. The entire process is managed to ensure orderly settlement.
Risk Management
The OCC collects margin from clearing members daily, maintains a clearing fund from member contributions, and conducts stress tests to ensure it can handle extreme market events. During the 2008 financial crisis and 2020 COVID crash, the OCC successfully settled all trades without interruption.
