A purchasing director receives a proposal to hedge next year's copper requirements. The forecast is moving, half the supplier contracts have fixed prices, and the company cannot quantify its remaining exposure.
Before discussing a derivative, procurement needs to establish which future cash costs remain sensitive to commodity prices.
Start with the cost that can still move
Raw-material price risk management can involve physical purchasing arrangements or financial instruments. Financial hedging specifically uses instruments such as futures, options or swaps to offset an identified price exposure. The aim is to protect cost or margin, not predict prices.
Purchase volume alone is a poor measure of hedgeable exposure. A business might consume a large quantity of aluminium while buying finished components at fixed prices. Another might buy relatively little copper directly but have supplier invoices that reset monthly against a metals index. Direct purchase volume therefore does not, by itself, show how much commodity price risk the business retains.
Procurement therefore needs to trace both purchase and customer pricing: which prices float, which are fixed, which indices and currencies apply, and when adjustments take effect. Matching mechanisms may naturally offset commodity movements; different indices, timing or pass-through limits can leave exposure to rising or falling prices. The relevant starting point is the business's remaining economic exposure after these effects are considered.
A fixed purchase price and a financial hedge are different commitments
There are several ways to reduce uncertainty. A fixed-price physical contract can stabilize the purchase price, if supplier performance and volume commitments hold. An index-linked contract makes changes transparent but leaves the buyer exposed to the index. A financial hedge can offset some remaining exposure without changing the physical supplier contract, provided purchase quantities, pricing index and timing are sufficiently aligned with the instrument.
If a supplier has already fixed the commodity element, adding a long futures position intended to protect against rising prices could create an unwanted market position. If the supplier hedges on the buyer's behalf, procurement needs to understand the pricing methodology, fees, unwind terms and responsibility for gains or losses when orders change.
A financial hedge does not secure delivery, product quality or supplier capacity. Those remain sourcing and operational risks, even when the reference price is protected.
The volume forecast is part of the risk
Consider an illustrative manufacturer planning to purchase copper-intensive assemblies over the next six months. Engineering expects a redesign that could reduce copper content per unit, while sales has not confirmed the launch volume. Treasury proposes hedging the copper content of the full forecast.
A redesign, delay or weaker orders could reduce the copper exposure. A financial position intended to offset physical purchases can then exceed the remaining exposure. Closing or adjusting it may crystallize a gain or loss. The wrong hedge size can turn cost protection into risk creation.
Confirmed orders, contracted requirements and uncertain pipeline demand should not be treated as equally firm. Companies may choose to hedge a smaller, better-supported portion of expected demand, while leaving flexibility around the remainder. The appropriate proportion is a business risk decision, not a universal industry percentage.
Matching the index is as important as choosing the direction
A futures contract can offset changes in an exchange-traded commodity price. The delivered material, however, may include premiums for grade, regional availability, transport or conversion. These components do not necessarily move with the exchange price.
The difference between a cash price and its reference futures price is known as basis. CME Group defines basis risk as uncertainty about how that price difference changes during a hedge (CME Group Glossary). A regional metal premium, for example, could rise even while the exchange-traded reference price is effectively hedged.
Procurement should therefore distinguish the priced commodity component from everything bundled into the supplier invoice. It should also check currency, contract period and volume units. An imperfect match may still be useful, but residual risk must be visible.
The cash requirement can arrive before the purchasing benefit
Financial protection has its own operating cost. Exchange-traded futures may require initial and variation margin; adverse market movements can create cash calls before the company pays for the physical material. Options can limit certain price risks while requiring a premium. Over-the-counter arrangements introduce contractual and counterparty considerations.
A hedge may ultimately support the intended purchase economics and still strain liquidity along the way. Treasury and finance must test that timing, alongside accounting treatment, credit limits and authorization. Where a company seeks cash flow hedge accounting under IFRS 9, the designated forecast transaction must be highly probable, with uncertainty over timing and magnitude considered (IFRS Foundation, March 2019). This is an accounting qualification, not a condition for every economic hedge.
Procurement's responsibility is to supply a defensible picture of contracts and anticipated purchases. Execution should sit with the function authorized under the company's risk policy, typically treasury, with finance assessing liquidity and accounting implications. These functions need to align before trading.
When leaving the exposure open is reasonable
Hedging is not automatically the mature choice. If demand is highly uncertain, the commodity component is small, customer pricing passes through input-cost changes sufficiently closely in timing and amount, or the available instrument tracks the purchase price poorly, the costs and complications may outweigh the protection. Supplier pricing mechanisms, inventory decisions or product redesign may be more suitable responses.
The decision should begin with three questions: What economic exposure remains after customer pricing is considered? How closely can a proposed hedge track it? Can we absorb volume changes, cash calls and potential losses? A clear answer can justify a hedge, a partial hedge or no hedge at all.
Before approving a hedge, the business should be able to document the exposure it intends to protect, the risks that will remain, and how it will respond if purchases or cash requirements change.
