What Is a Derivative?
A contract whose value is based on something else — why they exist and who uses them
What a Derivative Is
A derivative is a financial contract whose value is derived from something else — an underlying asset. That underlying can be a stock, a bond, a commodity, a currency, an index, or even an interest rate. The derivative itself does not represent ownership of the underlying. It is a contract about its price.
An airline knows it needs to buy 1 million barrels of jet fuel in 6 months. Today oil is $80/barrel. If oil rises to $100, that is $20 million in extra costs. To remove this risk, the airline enters a futures contract locking in the $80 price. It does not own any oil — it owns a contract about oil's price. That contract is a derivative.
The Main Types
| Derivative | What it is | Who uses it |
|---|---|---|
| Options | Right (not obligation) to buy/sell at a fixed price | Hedgers, income traders, speculators |
| Futures | Obligation to buy/sell at a fixed price on a set date | Commodity producers, institutions |
| CFDs | Contract to pay/receive the difference between entry and exit price | Retail speculators (high risk) |
| Swaps | Exchange of cash flows — e.g. fixed rate for floating rate | Banks, corporations, pension funds |
| Forwards | Like futures but OTC (not exchange-traded), customisable | Corporations hedging currency/commodity risk |
Why Derivatives Exist
The primary purpose is risk transfer. One party wants to remove a risk (hedger). Another party is willing to accept that risk in exchange for potential profit (speculator). Derivatives make this transfer efficient.
Without derivatives, a wheat farmer would be exposed to harvest-season price crashes. Without derivatives, a pension fund holding billions in equities could not cheaply protect against a market decline. Without derivatives, a UK company with USD revenues could not lock in a favourable exchange rate.
Derivatives also allow speculation with leverage — controlling a large position with a small deposit. This amplifies both gains and losses. For retail investors, the leverage is the primary danger. Most people who lose money on derivatives lose it through leveraged speculation, not hedging.
FAQs
Are derivatives inherently dangerous?
The instrument is neutral. A hammer can build a house or break a window. Derivatives used for hedging reduce risk. Derivatives used for leveraged speculation amplify it. The danger is in the use, not the instrument.
What caused the 2008 crisis — were derivatives involved?
Yes. Specifically mortgage-backed securities and credit default swaps on them. The problem was not derivatives per se but the mispricing of risk, opacity of exposure, and interconnectedness of institutions holding them.
Should a retail investor use derivatives?
Most should not — at least not leveraged speculation. An exception is selling covered calls on shares you already own (an options strategy) or using exchange-traded index options for portfolio protection. These require proper education first.
What is the notional value of the derivatives market?
The Bank for International Settlements estimates the gross notional value of OTC derivatives at over $700 trillion. This sounds alarming — but notional value overstates real exposure, as most positions are netted and collateralised.
Key takeaways
- A derivative is a contract whose value is based on an underlying asset — not ownership of it.
- Main types: options, futures, CFDs, swaps, forwards.
- Primary purpose: transferring risk from hedgers to those willing to accept it.
- Leverage is the core danger for retail investors — it amplifies losses as much as gains.
- Used appropriately, derivatives reduce risk. Used speculatively with leverage, they destroy accounts.
