How Options Are Created
Understanding Options Creation
Before you can buy or sell an options contract, someone has to create it. Unlike stocks, which are issued by corporations, options are created through a process coordinated by the Options Clearing Corporation (OCC). Understanding how options come into existence is fundamental to grasping market structure and how the entire options market functions.
The Role of the Options Clearing Corporation (OCC)
The Options Clearing Corporation is a self-regulatory organization and central clearinghouse for all equity, index, and currency options traded in the United States. When you trade options, you're not actually trading with the person on the other side of your transaction—you're trading with the OCC through a broker.
The OCC guarantees both sides of every options trade. This means if the seller of an options contract defaults or is unable to fulfill their obligations, the OCC steps in. This guarantee is what allows the options market to function smoothly without counterparty risk being a major concern for traders and investors.
The OCC maintains clearing members (typically large financial institutions and broker-dealers) that are responsible for settling trades and managing their customers' obligations. Your broker is either a clearing member or has arrangements with a clearing member to clear your trades.
How New Options Series Are Listed
New options contracts for a stock are created and listed on options exchanges through a standardized process. When a company's stock becomes eligible for options trading, the exchanges create a standard series of contracts at various strike prices and expirations.
For popular stocks, options exchanges continuously list new series as needed. When the current front-month expiration approaches (usually three weeks before expiration), exchanges automatically introduce the next monthly expiration. Additionally, for highly liquid stocks like Apple, Tesla, or the S&P 500 ETF (SPY), weekly options are listed—creating new contracts every week.
The strike prices are standardized. For stocks trading below $25, strikes are typically $2.50 apart. For stocks between $25-$200, they're $5.00 apart. For stocks above $200, they're typically $10.00 apart. This standardization makes it easier for traders to evaluate and compare contracts.
The Opening Process: Creation and The First Trade
When you "buy to open" an options contract, you're entering into a new options position. Simultaneously, someone else is "selling to open" that same contract. This coordinated action creates the contract on the market.
The writer (seller) is agreeing to certain rights and obligations. If they sold a call, they're promising that if the buyer exercises, they'll deliver 100 shares of the underlying stock at the strike price. If they sold a put, they're promising to buy 100 shares at the strike price if exercised.
The buyer is paying a premium (the price of the contract) to acquire the right to exercise. This premium is divided between the buyer (who receives it as compensation for taking on obligation) and the buyer (who pays it for the right).
Open Interest: Creation and Destruction
Open interest is the total number of outstanding options contracts (for a particular strike and expiration) that haven't been closed or exercised. Understanding open interest is critical because it tells you about liquidity and activity in a contract.
When you buy to open and someone sells to open (a new position created), open interest increases by one contract. When someone buys to close (exiting) and someone sells to close (also exiting), open interest decreases by one contract. When one trader buys to open and another buys to close simultaneously, open interest doesn't change.
High open interest generally indicates a popular, liquid contract. Low open interest means the contract is less actively traded, which can result in wider bid-ask spreads (higher trading costs). On expiration day, all remaining open interest must be closed, exercised, or expire worthless.
The Clearing and Settlement Process
After you submit an options trade on your broker's platform, multiple processes happen behind the scenes to ensure it's properly cleared and settled.
First, the exchange matches your order with a counterparty. Your broker and the counterparty's broker confirm the trade details (strike, expiration, quantity, price). The trade is sent to the OCC for clearing.
The OCC becomes the buyer to every seller and the seller to every buyer. This process is called "novation." From that moment, you no longer have a contractual relationship with the person on the other side of your trade—you have a relationship with the OCC.
Settlement typically occurs T+1 (one business day after the trade). For options, this means if you buy an option today, you must pay for it by the next business day. If you sell an option, you receive payment the next business day.
Counterparty Risk Elimination by the OCC
In many derivatives markets, counterparty risk is significant. But in U.S. options markets, the OCC's guarantee eliminates this concern. Here's how it works:
When you buy an option, the seller must post margin (capital set aside) to guarantee they can fulfill their obligation. The OCC monitors sellers' margin requirements daily. If a seller's position moves against them, they must deposit additional margin. If they fail to do so, the clearing broker will liquidate their position, and the OCC ensures the contract remains valid.
This system has worked seamlessly for decades. Even during financial crises, the OCC has maintained its guarantee. This is why options trading is relatively safe from a counterparty perspective—the risk of the person owing you money not being able to pay is virtually eliminated.
Market Maker Obligations and Risk Management
Market makers are traders or firms that provide liquidity by constantly quoting both bid (buy) and ask (sell) prices for options contracts. They profit from the bid-ask spread—the difference between the price they buy at and sell at.
In exchange for providing this liquidity, market makers have certain obligations. They must continuously quote prices and typically cannot refuse to trade once they've quoted a price (with certain exceptions). They must maintain inventory to accommodate customer orders.
Market makers use sophisticated hedging strategies to manage their risk. If they buy an option, they may short the underlying stock or buy other options to offset their delta (directional) exposure. If they sell an option, they may buy the stock to hedge. This continuous hedging activity actually contributes to the market's efficiency.
Without market makers, option bid-ask spreads would be much wider, and finding someone to trade with would be harder. The obligation to provide liquidity is compensated by their profit opportunity on the spread and their flexibility in managing their own hedges.
How Options Exchanges Work
In the United States, options are traded on several exchanges, each of which is regulated by the SEC and the OCC. The major options exchanges include:
- CBOE (Chicago Board Options Exchange): The largest options exchange by volume, handling the majority of U.S. options trades. CBOE also trades SPX and VIX options.
- ISE (International Securities Exchange): Uses electronic trading and specializes in equity options.
- PHLX (Philadelphia Stock Exchange): Part of Nasdaq, focuses on equity and currency options.
- NASDAQ OMX: Handles options on Nasdaq-listed stocks and ETFs.
- NYSE Arca: Part of NYSE, provides options trading on listed companies.
Each exchange has its own systems for matching orders, managing risk, and coordinating with the OCC. Brokers route options orders to the exchange with the best price available (or the broker may execute orders internally as a market maker).
The National Best Bid & Offer (NBBO) for Options
Just like with stocks, the NBBO represents the best available price to buy or sell an options contract across all exchanges. When you place a limit order to buy an option at a specific price, your broker should provide you execution at that price or better if the NBBO improves.
Options NBBO works differently than stock NBBO. For stocks, the NBBO is updated continuously in real-time. For options, the NBBO is calculated based on market maker quotes on various exchanges. The bid is the highest price any market maker is willing to pay, and the ask is the lowest price any market maker is willing to sell at.
The spread between bid and ask varies based on the contract's liquidity. In-the-money options and near-term expirations typically have tighter spreads. Out-of-the-money options and longer-dated contracts often have wider spreads.
Payment for Order Flow (PFOF) in Options
Many retail brokers now offer commission-free options trading, but they still make money through payment for order flow (PFOF). This means they sell your order flow to market makers, who profit by trading with you at slight disadvantages.
When you place an options order that gets routed to a market maker through PFOF, that market maker may quote prices slightly wider than the true NBBO, capturing a small profit. While regulators argue this benefits retail traders (via lower commissions), it also means you may receive slightly worse execution prices compared to institutional traders.
Understanding PFOF is important for traders placing limit orders. Market makers handling PFOF orders have incentive to improve the quote just enough to win your order, but not so much that they lose money. This dynamic affects how and where you should place your orders.
The Options Lifecycle: From Creation to Expiration
Every options contract follows a predictable lifecycle from creation to expiration:
| Stage | Description | Typical Timeline |
|---|---|---|
| Creation | Contract is first traded when buyer and seller agree to terms | Usually up to 9 months before expiration |
| Trading | Contract is actively traded, open interest grows, bid-ask spreads vary | Throughout the contract's life |
| Near Expiration | In the final weeks, time decay accelerates, Greeks shift significantly | Last 3-4 weeks before expiration |
| Final Day | Last trading day is typically 4:00 PM ET on the 3rd Friday of the month | One day before expiration |
| Expiration | In-the-money options are exercised, out-of-the-money expire worthless, or buyers can exercise/sellers assigned | Expiration Saturday |
Conclusion
Options creation is a carefully orchestrated process involving the OCC, options exchanges, brokers, market makers, and traders. The OCC's role as central clearinghouse eliminates counterparty risk and ensures market integrity. New options series are continuously listed, open interest fluctuates based on trader activity, and the entire market is designed to be efficient and liquid. Understanding this infrastructure helps you appreciate why options markets are so stable and accessible to individual traders.
