A commodity contract defines the quantity, quality, price, timing, delivery, settlement, margin, and default terms for physical or financial commodity exposure.
A commodity contract is an agreement that defines how a physical commodity or commodity-price exposure will be bought, sold, delivered, or financially settled. It may be a spot purchase, private forward, exchange-traded future, option, swap, or longer-term supply agreement.
The commodity name is not enough. Contract value and risk depend on quantity, unit, grade, quality, location, timing, price formula, settlement method, margin or collateral, and default rights.
| Contract term | Question to answer |
|---|---|
| Underlying | Which commodity, benchmark, index, or futures contract determines value? |
| Quantity and unit | How many barrels, bushels, tonnes, ounces, or other units? |
| Grade and quality | Which purity, class, moisture, sulfur, assay, or other standard applies? |
| Price | Fixed price, floating benchmark, differential, average, formula, or option payoff? |
| Delivery location | Which terminal, warehouse, pipeline point, port, or approved facility? |
| Timing | Trade date, pricing period, delivery month, notice date, and final settlement date? |
| Settlement | Physical delivery, cash settlement, offset, or another mechanism? |
| Credit support | Exchange margin, clearing guarantee, collateral, credit limit, or unsecured exposure? |
| Disruption terms | What happens after force majeure, delivery failure, benchmark disruption, or default? |
| Type | Trading and settlement model | Typical use |
|---|---|---|
| Spot cash transaction | Current cash-market transaction with prompt physical delivery at a stated spot price | Immediate procurement or sale |
| Forward | Private agreement for future delivery or settlement | Customized commercial hedge or purchase |
| Future | Standardized exchange contract cleared and margined under exchange rules | Hedging, speculation, price discovery, and risk transfer |
| Option | Right, but not obligation, tied to a commodity or futures contract | Price floor, ceiling, or directional exposure |
| Swap | OTC cash flows linked to a commodity price or index | Customized price-risk management |
| Supply or offtake agreement | Commercial purchase or sale across multiple deliveries | Procurement, production financing, and long-term sales |
A standardized commodity is not a separate financial asset. It is a commodity defined by uniform contract specifications so acceptable units can be treated as interchangeable for trading and delivery.
For a physically settled future, the exchange may specify:
Standardization improves fungibility: a market participant does not need to negotiate every term for every trade. It does not make every physical unit identical. A grade or location outside the contract specification may trade at a premium or discount in the cash market and may not be deliverable.
| Feature | Futures contract | Forward or supply contract |
|---|---|---|
| Terms | Standardized by the exchange | Negotiated between counterparties |
| Trading | Exchange market | Usually over the counter |
| Credit model | Clearinghouse and margin | Bilateral credit and collateral terms |
| Offset | Standardized positions can generally be closed with an opposite trade | Opposite contracts may create two separate obligations |
| Commercial fit | Liquid but may not match exact grade, location, or date | Can be tailored to the physical exposure |
| Main mismatch risk | Basis between the contract and actual commodity | Counterparty, documentation, and liquidity risk |
Assume a hypothetical metal future specifies 100 units of a stated purity at an approved warehouse during a named delivery month. A manufacturer expects to buy 95 units of a slightly different grade at another location.
The future may still reduce broad price risk, but the hedge is not exact:
Those differences create basis risk. A standardized contract can be highly liquid while remaining an imperfect commercial hedge.
