Hedging Mechanics: Forwards, Futures, and Basis Risk

Chapter 4 mentioned that futures let producers and consumers hedge real physical risk. This deep dive is about how that actually works in practice — the difference between a forward and a future, and the specific way a hedge can still leave a company exposed even when it's done "correctly."

Forwards vs. futures — same idea, different plumbing

A forward contract is a private, customizable agreement between two parties to transact at a set price on a future date — negotiated directly (over-the-counter, OTC), tailored to the exact quantity and date each party needs, but carrying counterparty risk: if the other side can't or won't honor the contract when it matters, you're exposed.

A futures contract is the standardized, exchange-traded version — fixed contract sizes, fixed expiration dates, and critically, a clearinghouse sits between both parties, guaranteeing performance and largely eliminating counterparty risk. The tradeoff: standardization means a futures contract often doesn't exactly match what a company actually needs (the exact quantity, the exact date), which is where basis risk (below) comes from.

Why a real company hedges at all

Take an airline: jet fuel is a huge, volatile cost, and the airline's core business is flying planes, not speculating on oil prices. Buying oil futures (or forwards) locks in a fuel cost months in advance, converting an unpredictable cost into a known one — the airline is willing to give up the chance of fuel getting cheaper in exchange for eliminating the risk of it getting drastically more expensive. This is hedging's actual purpose: reducing uncertainty in a core business input, not making a speculative bet.

Basis risk — the hedge that isn't quite perfect

Basis is the difference between a hedge instrument's price and the actual price of the specific thing being hedged. Basis risk arises because a standardized futures contract rarely matches a real company's exact exposure perfectly:

• Location basis: an airline buying crude oil futures is hedging against crude, but actually consumes jet fuel — related, but not identical, prices that don't always move in lockstep.
• Timing basis: the futures contract might expire in a different month than when the company actually needs to buy the physical commodity.
• Quantity/grade basis: the exact grade or specification of the futures contract's underlying commodity may differ slightly from what the company actually uses.

The practical consequence: a company can hedge "correctly" — following the textbook playbook exactly — and still end up with a result that doesn't perfectly offset its real cost, because the hedge and the actual exposure were never identical in the first place. Real corporate treasury and risk teams spend real effort managing basis risk, not just deciding whether to hedge.

Why this matters beyond commodities

The same forward-vs-futures and basis-risk logic applies directly to FX hedging (a company with foreign revenue hedging currency exposure) and interest rate hedging (a company with floating-rate debt hedging against rate rises) — it's a general risk-management framework, not something unique to oil and wheat. Recognizing "what's the basis risk here" is a genuinely useful question to ask about almost any hedge you encounter.
