Derivative securities are financial contracts whose value comes entirely from something else: a stock, a bond, a commodity, an interest rate, a currency, or a market index. You aren’t buying the underlying asset. You’re buying an agreement tied to its future price. That structure lets two parties transfer risk between them, and it lets a smaller amount of money control a much larger position. Both features explain why the over-the-counter portion of this market alone carried a notional value above $845 trillion as of mid-2025.
The rest of this article walks through what makes a contract a derivative, the main types you’ll encounter, how they settle, where they trade, who regulates them, and how they’re taxed.
What Makes a Contract a Derivative
The name is literal. A derivative’s value is derived from an underlying reference. That reference can be almost anything with a measurable price: stocks, government bonds, crude oil, gold, the S&P 500, interest rates, foreign currencies, even weather data.
The contract itself isn’t the asset. An oil futures contract doesn’t put a barrel of crude in your garage. You hold an agreement to buy or sell that oil at a set price on a set date. The derivative’s price tracks the underlying, but not in lockstep. Time to expiration, volatility, interest rates, and demand for the contract itself all move the price on their own.
Leverage is the defining financial trait. A derivative usually requires only a fraction of the underlying’s value as an upfront deposit, so a small move in the underlying translates into a large percentage swing on the money actually at risk. A 2% move in crude oil can produce a 20% swing in an oil futures position. That amplification runs both directions, which is why derivatives generate outsized gains and devastating losses at equal speed.
The Main Types of Derivatives
Futures and Forwards
Futures and forwards are the most straightforward derivatives: binding agreements to buy or sell an asset at a set price on a future date. Both sides are obligated to perform. The buyer takes a “long” position; the seller takes a “short” position. A corn farmer might sell futures to lock in a harvest price, and a food manufacturer might buy them to lock in input costs. Both sides eliminate price uncertainty and give up potential upside in exchange.
Forwards are private, customized contracts negotiated between two parties, often a corporation and a bank. Size, quality, delivery date, and settlement method are all negotiable. The trade-off is credit risk: each party bears the full risk that the other cannot pay, because no intermediary guarantees performance.
Futures are the standardized cousin. Contract size, expiration dates, and deliverable asset quality are fixed by the exchange, which is what makes the market so liquid — every contract is interchangeable. The exchange’s clearinghouse stands between every buyer and seller, acting as counterparty to both sides. If one party defaults, the clearinghouse absorbs the loss instead of passing it on.1CME Group. Definition of a Futures Contract
Options
Options work differently from futures in one fundamental respect: the buyer has a right, not an obligation. You pay a premium for the right to buy or sell an underlying asset at a fixed strike price before or on a specific expiration date. If exercising isn’t profitable, you walk away and lose only the premium. That asymmetry is what makes options useful for capping downside while keeping upside open.
A call option gives you the right to buy at the strike price. Buyers of calls expect the underlying to rise. If it climbs above the strike by more than the premium paid, they profit; if it doesn’t, they let the option expire.
A put option gives you the right to sell at the strike price. Buyers of puts either expect a decline or own the underlying asset and want insurance against one.
The option seller, called the writer, collects the premium upfront and takes on the obligation to perform if the buyer exercises. Writing is a different risk profile from buying. A covered call writer — someone who sells calls against stock they already own — has limited downside. A naked call writer, who sells calls without owning the underlying, faces theoretically unlimited losses if the stock surges, because there’s no ceiling on how high a stock can go. Naked call writing is the riskiest common options strategy and is restricted to the most experienced and well-capitalized traders for that reason.
Options also come in two exercise styles. American-style options can be exercised on any business day before expiration. European-style options can be exercised only at expiration.2Options Clearing Corporation. Index Options The labels have nothing to do with geography. Most individual stock options in the U.S. are American-style; many index options are European-style.
Swaps
Swaps are agreements between two parties to exchange streams of cash flows over time, usually based on different reference rates or currencies. They’re less visible to individual investors than futures or options, but far larger in total market size, and they’re the workhorses of institutional finance.
Interest rate swaps are the most common. One party pays a fixed rate and receives a floating rate from the counterparty, or the reverse. A company carrying a floating-rate loan might enter a swap to convert its payments to fixed, taking the risk of rising rates off its balance sheet. The swap doesn’t change the underlying loan. It’s a separate contract that offsets the variable payments. A reference amount, called notional principal, sizes the payments, but the principal itself never changes hands.
Currency swaps exchange both principal and interest in one currency for those in another. A U.S. company with revenue in euros can use a currency swap to lock in exchange rates for future cash flows.
Credit default swaps function like insurance against a borrower’s default. The buyer makes periodic payments; if the referenced borrower defaults, the seller pays out. CDS contracts drew intense scrutiny during the 2008 financial crisis, when the sheer volume outstanding — much of it written by firms without the capital to honor the contracts — amplified losses across the financial system. Post-crisis reforms have pushed many standardized CDS contracts toward central clearing.3Commodity Futures Trading Commission. Clearing Requirement
Warrants
Warrants resemble long-dated call options but are issued by a company itself rather than created through exchange trading. A warrant gives the holder the right to buy the company’s stock at a set price, often years in the future. When exercised, the company issues new shares, which dilutes existing shareholders. That’s the key difference from standard options, where no new shares are created.
Why People Use Derivatives
Derivatives serve three main economic functions, and the three together explain why the market is so large relative to the assets it references.
Hedging uses a derivative to offset a risk you already carry. A commercial airline faces real exposure to rising jet fuel prices. A futures contract that locks in a purchase price six months out removes that uncertainty from operating costs. The risk doesn’t vanish. It transfers to a counterparty willing to accept it in exchange for potential profit. Farmers selling grain futures before harvest, manufacturers locking in raw material costs, and banks managing interest rate exposure on their loan portfolios all hedge this way.
Speculation is the opposite posture: taking on risk deliberately to profit from a price move. A trader who expects the S&P 500 to rise can buy index futures instead of purchasing all 500 stocks. The leverage embedded in the contract means the trader controls a large notional position on a relatively small margin deposit. If the index climbs, profits are magnified. If it falls, losses are equally magnified and can exceed the initial deposit. Speculators are essential to functioning markets even without any natural exposure to the underlying, because they provide the liquidity hedgers need on the other side of every trade.
Arbitrage means buying and selling closely related assets simultaneously in different markets to capture small price gaps. If a stock’s price diverges from the price implied by its futures contract, arbitrageurs trade both until the gap closes. That activity keeps derivative prices tethered to the underlying assets, which benefits everyone else in the market.
How Contracts Settle
When a derivative expires, it settles one of two ways. Physical delivery means the actual asset changes hands: the seller delivers barrels of oil, bushels of wheat, or gold bars. This is common for agricultural and energy commodities and involves real logistics — transportation, storage, insurance.
Cash settlement skips the physical exchange. The clearinghouse compares the contract price to the market price at expiration and credits or debits the difference. Financial derivatives like stock index futures and interest rate contracts almost always settle in cash. Most retail traders never intend to take delivery, and brokers enforce rules to close out physically settled positions before expiration to prevent accidental delivery obligations.
Margin and Mark-to-Market
Futures traders don’t pay the full contract value upfront. They deposit initial margin — a performance bond — with their broker. The clearinghouse sets the amount based on the contract’s volatility and notional value.4CME Group. Understanding Margin Changes
Positions are marked to market at least daily. Gains and losses are calculated against the current settlement price and credited or debited to the account in real time.5Financial Industry Regulatory Authority. FINRA Rule 4210 – Margin Requirements If losses push the account below the maintenance margin level, typically 50% to 75% of initial margin, the broker issues a margin call requiring the trader to restore the account to the initial margin. Failure to meet a margin call promptly results in the broker liquidating the position, sometimes automatically and without notice. This is where leverage turns dangerous. A modest adverse move can wipe out the entire margin deposit in a single session.
Where Derivatives Trade
The trading venue shapes almost everything about a derivative’s risk profile, transparency, and regulatory treatment. Two market structures exist, and the differences between them matter more than most beginners realize.
Exchange-Traded Derivatives
Futures and most options trade on regulated exchanges — the CME Group for futures, Cboe for many options. Contracts are standardized, prices are publicly visible, and a central clearinghouse guarantees performance on both sides of every trade.1CME Group. Definition of a Futures Contract For exchange-traded options, the Options Clearing Corporation serves as central counterparty, acting as buyer to every seller and seller to every buyer.6Options Clearing Corporation. Clearance and Settlement Counterparty default is effectively a non-issue for individual traders in this structure.
Over-the-Counter Derivatives
Forwards, swaps, and many exotic derivatives trade over the counter — privately negotiated between two parties, usually large financial institutions. OTC contracts can be tailored to exact specifications, which is their main advantage. The main disadvantage is counterparty risk. If the other side can’t pay, you bear the loss directly.
The 2008 crisis showed how dangerous concentrated OTC exposures could become. The Dodd-Frank Act responded by requiring standardized OTC swaps to be cleared through central counterparties and reported to swap data repositories.7Legal Information Institute. Dodd-Frank Title VII – Wall Street Transparency and Accountability Swap dealers must register with the CFTC and comply with capital, margin, and reporting requirements for uncleared swaps.8eCFR. 17 CFR Part 23 – Swap Dealers and Major Swap Participants
Who Regulates Derivative Securities
Two federal agencies split primary responsibility in the United States. The Commodity Futures Trading Commission holds exclusive jurisdiction over futures contracts and swaps traded on designated contract markets and swap execution facilities.9Office of the Law Revision Counsel. 7 USC 2 – Jurisdiction of Commission That covers agricultural commodity futures, interest rate swaps, and credit default swaps. The Securities and Exchange Commission oversees securities-based derivatives, including options on individual stocks and security futures. Where products straddle both jurisdictions — options on securities, for instance — the two agencies share authority.
Dodd-Frank, enacted after the 2008 crisis, sharply expanded oversight of OTC derivatives. It mandated central clearing for standardized swaps, created reporting obligations, and imposed registration and capital requirements on swap dealers.3Commodity Futures Trading Commission. Clearing Requirement Before Dodd-Frank, the OTC market operated with minimal transparency.
Tax Treatment
Derivative taxation has rules that surprise people who didn’t read the fine print. Treatment depends on the type of contract, how long it was held, and sometimes what the underlying is.
Section 1256 Contracts
Regulated futures contracts, broad-based index options like SPX options, and options on futures get special tax treatment. Regardless of actual holding period, gains and losses are automatically split: 60% long-term capital gains and 40% short-term.10Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market Because long-term capital gains rates are lower than short-term rates for most taxpayers, that blend can produce a meaningful advantage over trading individual stocks.
These contracts are also marked to market at year-end. Even on an open position, you’re treated as though you sold it at fair market value on the last business day of the year, and gain or loss is recognized for that tax year.10Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market You can’t defer gains on open positions the way you can with stocks.
Wash Sales and Options
Sell a stock at a loss, then buy a call option on that same stock within 30 days before or after, and the wash sale rule disallows the loss deduction. The rule explicitly covers contracts and options to acquire substantially identical securities, not just repurchases of the same stock.11Office of the Law Revision Counsel. 26 USC 1091 – Loss From Wash Sales of Stock or Securities The disallowed loss is added to the cost basis of the replacement position, so it’s not lost permanently, but the timing shift can create unexpected tax liability in the current year. The wash sale rule does not apply to Section 1256 contracts, since those are already marked to market annually.
Getting Approved to Trade and What SIPC Covers
You can’t simply open a brokerage account and start selling naked calls. Brokers impose tiered approval levels for options trading, typically ranging from Level 1 (covered calls and similar low-risk strategies) through Level 4 (uncovered options and complex multi-leg positions). Higher levels require demonstrating more experience, higher income or net worth, and a greater stated risk tolerance. Your broker evaluates the application and assigns a level, and you’re restricted to strategies within it.
For futures, traders open a separate futures account and meet initial margin set by the exchange and the broker.
If a brokerage firm fails, the Securities Investor Protection Corporation protects customer accounts up to $500,000, including a $250,000 sublimit for cash.12Securities Investor Protection Corporation. What SIPC Protects That extends to options, security futures, and other securities held in the account. It does not cover commodity futures contracts unless they’re held in a special portfolio margining account approved by the SEC.13Securities Investor Protection Corporation. Resources – FAQs SIPC also doesn’t protect against investment losses. It steps in only when a member firm fails and customer assets are missing. Commodity futures accounts are subject to segregation rules enforced by the CFTC rather than SIPC coverage, and recovering assets from a failed futures commission merchant follows a different process entirely.
