A derivative is a financial contract whose value is linked to an underlying reference, such as a share, stock index, currency, commodity, interest rate or credit event. Derivatives are used by companies, investors, banks and market makers to transfer or reshape financial risk. They can also amplify risk when positions are leveraged or poorly understood.
Why derivatives exist
Businesses use derivatives to reduce uncertainty. An airline may seek to manage fuel-price exposure; an exporter may hedge currency receipts; a borrower may manage interest-rate exposure. Investors may use derivatives to adjust portfolio exposure without buying or selling the underlying asset. Market makers use them to facilitate trading and manage inventory risk.
Four common derivative types
Forwards
A forward is a privately negotiated agreement to transact an asset or cash flow at a future date under agreed terms. It can be tailored to a specific need, but the parties face counterparty and documentation risks.
Futures
Futures are standardised contracts traded on an exchange and cleared through a clearing house. Margining and daily settlement help manage counterparty exposure, though market and liquidity risks remain.
Options
Options give the buyer a right, not an obligation, to buy or sell under specified terms. The buyer pays a premium; the seller accepts an obligation. Option values depend on the underlying price, time, volatility and other variables.
Swaps
Swaps exchange cash flows according to agreed formulas. Interest-rate swaps, for example, may exchange fixed-rate payments for floating-rate payments. Currency swaps can exchange principal and interest flows in different currencies.
How derivatives are valued
Valuation depends on contract design and the underlying market. Futures prices may reflect spot prices, financing, storage, dividends or convenience yield. Option pricing is sensitive to the underlying price, strike, time to expiry, volatility and interest rates. Swap values depend on the expected future cash flows and discount rates. Model estimates are not guarantees of executable market prices.
Risks to understand
- Market risk: the underlying moves against the position.
- Leverage risk: a small initial deposit controls a larger exposure.
- Counterparty risk: an OTC counterparty may fail to perform.
- Liquidity risk: closing or adjusting a position may be costly.
- Basis risk: the hedge and the exposure do not move together perfectly.
- Operational and legal risk: documentation, collateral or settlement processes fail.
Exchange-traded versus OTC derivatives
Exchange-traded contracts are standardised and generally benefit from central clearing. Over-the-counter contracts can be customised but require careful attention to counterparty credit, collateral, valuation and legal documentation. Neither structure eliminates risk; each changes how risk is managed.
Questions to ask before using a derivative
What exposure are you hedging or seeking? What is the contract’s notional value? How are collateral and margin calculated? What happens at expiry or termination? What are the stress losses under adverse scenarios? Is the contract liquid, and can you explain the payoff without relying on a broker’s sales description?
Frequently asked questions
Are derivatives only used for speculation?
No. They are widely used for hedging and risk transfer, although they can also be used for directional trading.
Are all derivatives leveraged?
Many create leveraged exposure, but the degree and mechanics depend on the contract and collateral arrangements.
Can a hedge still lose money?
Yes. Basis risk, timing differences, imperfect sizing and changing exposures can cause a hedge to underperform.
Bottom line: Derivatives are tools for transferring and reshaping risk. Their usefulness depends on matching the instrument to a clearly defined exposure and understanding the full contract obligations.
