Currency, Commodity, and Basis Risk

Currency, commodity, and basis risks are market risks that can change cash flows, costs, revenue, investment returns, and hedge effectiveness. Currency risk concerns exchange-rate movements, commodity risk concerns physical and derivative commodity exposures, and basis risk concerns an imperfect relationship between a hedge and the exposure it is intended to offset.

These risks often interact. A manufacturer may face a commodity purchase priced against a futures benchmark, settle the invoice in a foreign currency, and use a hedge whose location or maturity does not exactly match the purchase.

Key Takeaways

• Start with the underlying cash flow or position, not the derivative used to hedge it.
• Record amount, currency, commodity, benchmark, location, quality, and timing.
• A hedge can reduce outright price risk while leaving basis, volume, liquidity, and counterparty risk.
• Risk should be evaluated on the combined exposure and hedge result, not on either position in isolation.
• Historical correlation and volatility are evidence, not guarantees that relationships will continue.

How the Risks Interact

Assume a Canadian manufacturer expects to buy a U.S.-dollar-priced industrial commodity in three months.

1. The manufacturer faces commodity risk if the commodity price rises.
2. It faces currency risk if the U.S. dollar strengthens against the Canadian dollar.
3. It faces basis risk if its futures hedge references a different delivery location, grade, or month from the physical purchase.
4. It can face liquidity risk if the hedge requires margin before the physical purchase occurs.
5. It can face volume risk if the required quantity changes.

Buying commodity futures may address part of the price exposure without addressing the currency conversion. A currency forward may address a forecast U.S.-dollar payment without fixing the commodity quantity. A useful hedge program therefore maps each instrument to a specific source of risk.

Minimum Evidence for Review

Before relying on a risk number or hedge conclusion, check:

• the legal entity and reporting currency
• the physical or financial amount exposed
• the expected transaction and settlement dates
• the commodity grade, location, and delivery terms
• the exchange-rate and commodity-price quote conventions
• the benchmark and maturity of each hedge
• the forecast range for quantity and timing
• margin, collateral, financing, and transaction costs
• counterparty and termination terms
• stress scenarios for price, basis, liquidity, and volume

The objective should also be explicit. A business may seek budget certainty, margin protection, cash-flow stability, or compliance with a risk limit. Those objectives can imply different hedge instruments and tolerances.
