A derivative security is a financial contract between two parties whose value is derived from an underlying asset, rate, or index rather than from anything the contract owns itself. The reference point can be a stock, a bond, a commodity like oil or wheat, an interest rate, a currency pair, or the creditworthiness of a borrower. When that underlying moves, the derivative’s price moves with it. The global over-the-counter derivatives market alone reached roughly $846 trillion in notional value by mid-2025, which gives some sense of how widely these contracts are used.1Bank for International Settlements. OTC Derivatives Statistics at End-June 2025
How the Value Is Derived
A derivative has no standalone worth. A share of stock represents a claim on a company’s earnings and assets; a bond represents a claim on future coupon and principal payments. A derivative represents neither. It’s an agreement about what one party will pay the other based on how the underlying reference behaves over time.
That structure is why the same underlying can support many different contracts. A single stock can back listed call options, put options, single-stock futures, and privately negotiated swaps, each with its own payoff formula. The stock is the reference; the derivatives are separate contracts written against it.
Notional Value and Leverage
Every derivative has a notional value, which is the face amount the contract is calculated from. A futures contract covering 1,000 barrels of oil at $80 per barrel has a notional value of $80,000. Payments and profits flow from that number, but you don’t post $80,000 to enter the trade. You post a margin deposit that is a small fraction of it.
That gap between what you control and what you put up is leverage, and it defines how derivatives behave. Posting $5,000 to control a $100,000 position gives you 20-to-1 leverage. A 5% move in your favor doubles your money. A 5% move against you wipes out your entire deposit, and with futures you can owe more than that when the position is closed.
The Main Types of Derivatives
Derivative contracts fall into four broad categories. The clearest dividing line runs between contracts that obligate both parties to transact and contracts that give one party the right to walk away.
Futures Contracts
A futures contract is a standardized agreement to buy or sell a specific quantity of an asset at a set price on a future date. Futures trade on regulated exchanges such as the CME Group, and every trade clears through a central clearinghouse that acts as the buyer to every seller and the seller to every buyer. That structure largely eliminates the risk of the other side defaulting.2CME Group. Definition of a Futures Contract
Futures are marked to market daily. Gains and losses are settled into your account at the end of each trading day rather than accumulating until the contract expires. If losses push your account below the maintenance margin level, you’ll get a margin call requiring you to add funds immediately, and failing to meet it lets the broker liquidate your position without asking. At expiration, most futures settle in cash, though physically delivered contracts still exist for commodities like oil, gold, and grain.3CME Group. Cash Settlement vs. Physical Delivery
Forward Contracts
A forward contract is the private cousin of a futures contract. Two parties agree on a price for a future transaction, but the deal is negotiated directly and customized to whatever terms both sides want, from the exact quantity to the settlement date.
The tradeoff is counterparty risk. No clearinghouse stands between the parties, so if the other side can’t pay at settlement, you’re exposed. Large financial institutions manage this by negotiating forwards under an ISDA Master Agreement, a standardized legal framework governing how defaults, disputes, and terminations are handled across all transactions between the parties.4U.S. Securities and Exchange Commission. ISDA 2002 Master Agreement Forwards aren’t settled daily; the entire gain or loss is realized at expiration.
Options Contracts
An options contract gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a set price (the strike) before or on the expiration date. If the trade doesn’t make sense, the buyer walks away and lets the option expire. The seller, by contrast, is obligated to fulfill the transaction if the buyer exercises.
A call gives the buyer the right to buy at the strike, which becomes valuable when the underlying rises above that level. A put gives the buyer the right to sell at the strike, which pays off when the underlying falls below it. The buyer pays a premium up front, and that premium is the maximum the buyer can lose. The seller collects the premium but takes on the other side of the risk, and for uncovered calls the potential loss is theoretically unlimited because there’s no cap on how high a price can climb.
Swaps
A swap is an agreement in which two parties exchange streams of cash flows over a set period. Federal law defines swaps broadly as agreements that transfer financial risk tied to rates, currencies, commodities, or other economic measures between parties.5Office of the Law Revision Counsel. 7 U.S. Code 1a – Definitions
The most common form is the interest rate swap. One party pays a fixed rate on a notional principal amount while the other pays a floating rate on the same amount, with the principal itself never changing hands. A company with a floating-rate loan that wants predictable payments might swap its floating obligation for a fixed one, locking in its interest costs. Currency swaps go further and exchange both interest payments and principal amounts in two different currencies.
What Derivatives Are Based On
Nearly anything with a measurable price or rate can serve as the underlying reference. The major categories are:
- Equities: options and futures on individual stocks or on indexes like the S&P 500.
- Commodities: futures on crude oil, natural gas, metals, and agricultural products, used by producers and consumers to lock in prices ahead of delivery.
- Interest rates: swaps and futures tied to benchmark rates that let banks and corporations manage borrowing costs.
- Currencies: forwards and options on exchange rates, used by companies with foreign revenue or expenses.
- Credit: credit default swaps, in which one party pays a periodic fee in exchange for protection against a borrower defaulting on its debt.6Legal Information Institute. Credit Default Swap
How Derivatives Are Used
Derivatives exist to move risk from parties who don’t want it to parties willing to take it on. Every trade has someone on each side of that equation.
Hedging
Hedging means using a derivative to offset a risk you already carry. A U.S. manufacturer expecting a €10 million payment in six months faces the risk that the euro drops against the dollar before the money arrives. A forward contract to sell euros at today’s rate removes that exposure and locks in the dollar value of the incoming payment. A farmer sells corn futures before the harvest to guarantee a price. An airline buys fuel futures to stabilize operating costs. In each case the hedger gives up potential upside in exchange for certainty.
Speculation
Speculators take the other side. They enter derivative positions specifically to profit from price movements, absorbing the risk that hedgers want to shed. Without speculators providing liquidity, hedgers would have a much harder time finding someone to trade with.
Leverage is what makes derivatives attractive for speculation. Buying call options on a stock costs a fraction of buying the shares outright, and if the stock rises sharply, the percentage return on the options can dwarf what owning the shares would have produced. If the stock doesn’t move enough before expiration, though, the entire premium evaporates. To keep speculation from distorting commodity prices, the CFTC imposes position limits on how many futures contracts a single trader can hold. These limits apply to 25 core physically-settled commodity contracts, with spot-month limits set at or below 25% of estimated deliverable supply.7Commodity Futures Trading Commission. Position Limits for Derivatives
The Main Risks
The same leverage that amplifies gains amplifies losses. With futures and short options, you can lose more than your entire initial investment. If the market moves far enough against you, your margin deposit is gone and you still owe money to your broker.
A 20-to-1 leverage ratio means a 5% adverse move wipes out 100% of your margin. Markets routinely move much more than that in a single session around earnings, geopolitical events, or liquidity crunches. Daily mark-to-market settlement in futures means losses hit your account in real time, and margin calls can arrive before you’ve had a chance to react.
Counterparty risk is the second concern. Exchange-traded derivatives largely solve it through central clearing, but over-the-counter contracts like forwards and many swaps don’t have that protection. If your counterparty goes bankrupt before settlement, your expected payout may vanish. The 2008 financial crisis showed how dangerous concentrated OTC exposure could become, which led to the Dodd-Frank reforms requiring central clearing for many swaps.
Complexity and liquidity risk round out the picture. Exotic or highly customized derivatives can be difficult to value and hard to exit before expiration. If the market for your specific contract is thin, you may not find a buyer at a reasonable price when you need one, and that problem is especially pronounced in OTC markets where there’s no continuous exchange order book.
Who Regulates Derivatives in the U.S.
Derivatives fall under two primary regulators depending on the underlying. The Commodity Futures Trading Commission oversees futures, commodity options, and most swaps. The Securities and Exchange Commission regulates security-based swaps tied to individual equities or narrow credit indexes, along with equity options traded on securities exchanges.8Congress.gov. Introduction to Derivatives and the Commodity Futures Trading Commission
The Dodd-Frank Act reshaped how OTC derivatives are regulated after the 2008 crisis. Most swaps now must be centrally cleared, cleared swaps must trade on exchanges or swap execution facilities, every swap must be reported to a data repository, major swap dealers must register with the CFTC or SEC, and swaps that remain uncleared are subject to margin and capital requirements. One practical exception is worth knowing: when one side of the swap is a nonfinancial company hedging a commercial risk, such as an airline locking in fuel prices, that swap may be exempt from the clearing and exchange-trading requirements.8Congress.gov.
