A derivative is a financial contract whose value depends on the price of something else — an underlying asset. The contract itself is not a stock, bond, or barrel of oil. It derives its value from that asset's price movements. Derivatives are how the financial industry manages risk, expresses views, and connects markets.
There are four building blocks. A forward is a private agreement to buy or sell an asset at a set price on a future date. A future is the same idea, but standardised and traded on an exchange with daily margin settlement. An option gives the buyer the right — but not the obligation — to buy (call) or sell (put) at a fixed price. A swap is an agreement to exchange cash flows: most commonly, fixed interest payments for floating ones.
Every complex derivative — barrier options, autocallables, credit default swaps — is built from combinations of these four.
An airline expects to burn 10 million gallons of jet fuel next quarter. Today's price is $2.50 per gallon. The airline buys futures contracts locking in $2.50. If fuel rises to $3.00, the airline saves $5 million. If fuel drops to $2.00, the airline overpays by $5 million — but the budget is predictable. That predictability is the point. The airline is not speculating. It is hedging: exchanging price uncertainty for a known cost.
Three reasons. Hedging: the airline example above. Reducing or eliminating a specific risk. Speculation: a trader who believes a stock will rise buys call options instead of shares. If the stock goes from $100 to $110, a call option bought for $3 might be worth $10 — a 233% return versus 10% on the stock. The leverage works both ways. Arbitrage: exploiting pricing discrepancies. If a forward price deviates from its theoretical no-arbitrage value (spot plus carry cost), arbitrageurs force it back into line.
The global derivatives market exceeds $600 trillion in notional value — roughly 6 times global GDP. Most of this is in interest rate derivatives (swaps, futures, options on rates). Foreign exchange derivatives are second. Equity and commodity derivatives, despite their visibility, are a smaller share. The market is split between exchange-traded derivatives (standardised, centrally cleared) and over-the-counter (OTC) derivatives (customised, bilateral).
A derivative is a financial contract between two parties whose value is based on an underlying asset — such as a stock, bond, interest rate, or commodity. The contract itself is not the asset. It derives its value from the asset's price movements. Common examples include futures contracts on oil, call options on stocks, and interest rate swaps.
The four main types are forwards (private agreements to buy or sell at a future date), futures (standardised exchange-traded forwards), options (the right but not the obligation to buy or sell), and swaps (agreements to exchange cash flows, such as fixed for floating interest rates). Each serves different hedging, speculation, and arbitrage purposes.
Derivatives exist for three reasons: hedging (reducing risk — an airline buys oil futures to lock in fuel costs), speculation (taking a view on price direction with leverage — buying call options instead of shares), and arbitrage (exploiting price discrepancies between markets). The global derivatives market is estimated at over $600 trillion in notional value.
