Commodity Price Risk in Corporate Treasury

Commodity price risk is the risk that moves in the prices of commodities a company buys or sells hurt its finances — jet fuel for an airline, metals for a manufacturer, grain for a food company, crude for a producer. It's a market risk, like FX and interest rate risk, and it's managed with the same logic — identify, measure, manage, monitor — but it has its own quirks: commodity prices are often more volatile, exposure is frequently indirect, and hedging carries basis risk that makes it imperfect. It's also the market risk most often owned jointly with procurement and the commercial side, rather than by treasury alone.

What it is

Any company whose costs or revenues depend materially on a commodity price it doesn't control has commodity price risk. Two directions:

• On the buy side — input costs. A manufacturer's metals, an airline's fuel, a food producer's crops. When the commodity rises, margins compress.
• On the sell side — output prices. A miner, farmer or oil producer whose revenue rises and falls with the price of what it sells.

Either way, an uncontrolled price move flows straight to the bottom line.

How it differs from FX and rates

Commodity risk shares the market-risk framework but has features FX and rates don't:

• Higher volatility. Commodity prices can swing far more sharply than currencies or rates.
• Indirect exposure. You may be exposed to a commodity you don't buy directly — its cost is embedded in a supplier's price. That hidden exposure is easy to miss.
• Basis risk. The traded hedging instrument rarely matches your exact commodity, grade, location and timing — so hedges are imperfect in a specific way (more below).

Managing it: natural first

As with FX, reduce exposure structurally before hedging financially:

• Pass-through pricing — moving the commodity cost to customers via price, so a rise in input cost is recovered in revenue.
• Fixed-price or indexed supplier contracts — locking input costs, or tying them to a known index.
• Matching — aligning the timing and currency of purchases and sales so exposures partly offset.

Where the business can pass the cost on or contract it away, that's usually cheaper and simpler than a financial hedge.

Financial hedging — and basis risk

For the residual, companies use commodity derivatives — futures, forwards, swaps and options — to offset price exposure, exactly as with FX instruments. But commodity hedging carries basis risk more acutely: the liquid traded contract (a benchmark grade, at a benchmark location, for a standard date) may differ from your actual commodity, quality, delivery point and timing. So the hedge offsets the benchmark move but not perfectly your move — leaving a residual "basis" you have to understand and accept. A commodity hedge is rarely the clean offset an FX forward can be.

Whose risk is it?

Unlike FX and rates — usually treasury's domain — commodity risk is often shared. Procurement owns supplier contracts, the commercial side owns pricing, and treasury owns the financial hedging and the framework. Managing it well means these functions working together, with a clear policy on who does what. Commodity risk falls through the cracks precisely when everyone assumes someone else owns it.

What usually goes wrong

• Ignoring indirect exposure. Hedging only directly-purchased commodities and missing the exposure embedded in suppliers' prices.
• Underestimating basis risk. Treating a benchmark hedge as a perfect offset, then being surprised by the residual basis.
• Over-hedging. Hedging forecast volumes so aggressively that if they don't materialize, the hedge becomes a speculative position on the commodity.
• No policy / no clear owner. Commodity risk left between procurement, commercial and treasury, so it's managed by no one.
• Forgetting natural options. Reaching for derivatives when pass-through pricing or a supplier contract would have handled it.

Map the exposure including the indirect part, reduce it naturally where you can, hedge the residual with eyes open about basis risk, and give it a clear cross-functional owner under policy — and commodity price risk becomes a managed exposure rather than the volatile line that quietly wrecks a margin. It's the market risk that most needs treasury and the business to manage it together.
