Foreign Exchange Risk Management#
A 10% currency move on a 10% margin product eliminates all profit. FX hedging is not speculation — it's protecting known cash flows. Natural hedges (matching revenue and cost currencies) are free. Financial hedges (forwards, options) cost 0.5-2% of transaction value. Rule: hedge 50-80% of forecast exposure for 6-12 months forward. Leave 20-50% unhedged to benefit from favorable moves.
Forward Contracts vs Options#
Forwards: lock in an exchange rate for a future date. Zero upfront cost but you're locked in — can't benefit from favorable moves. Best for: known, committed cash flows. Options: pay a premium (1-3% of notional) for the right but not obligation to exchange at a set rate. Benefit from favorable moves, protected against unfavorable. Best for: uncertain cash flows (bid proposals, forecasts).
Building an FX Hedging Policy#
Document: what exposure to hedge (committed vs forecast), hedge ratio (50-80%), instruments allowed (forwards, options, no speculation), hedge tenor (6-12 months), and authorized signatories. Review policy annually. Without a policy, FX management becomes reactive — you hedge when scared and don't hedge when comfortable, which is backwards.
A Margin Wipeout, Walked Through Step by Step#
A Manchester-based industrial parts distributor signed a 6-month supply agreement with a Brazilian manufacturer, invoicing in Brazilian real, at a contract price that penciled out to an 11% gross margin when the deal was signed. Over the following four months the real depreciated against the pound by roughly 9%, driven by domestic interest rate moves in Brazil unrelated to the underlying trade. Because the distributor had not hedged and simply converted real receipts to pounds at spot rate as invoices were paid, the effective margin on the second half of the contract's shipments fell to just over 2% — barely covering overhead. Nothing about the underlying business changed: unit costs, sale price, and volumes were exactly as planned. The entire swing came from currency. Had the company locked in a forward rate for 60-70% of the contract's expected real receipts the day the contract was signed, the bulk of that margin would have been protected, with the unhedged portion left to capture any favorable move. This is the central case for hedging as risk management, not speculation — the company wasn't betting the currency would move in its favor, it was protecting a margin that already existed on paper the moment the contract was priced.
Matching the Hedge Instrument to the Type of Exposure#
Not all FX exposure looks the same, and the right instrument depends on how certain the cash flow is. A confirmed purchase order with a fixed delivery date and fixed price is a known, committed exposure — a forward contract is usually the right tool because there's no upside being given up (the cash flow is fixed regardless) and forwards carry no upfront premium. A sales forecast or a bid submitted for a contract that hasn't been won yet is a contingent exposure — hedging it with a forward is risky because if the deal doesn't close, the company is left with an open FX position with nothing behind it; an option is usually better here since it can be allowed to expire worthless for the cost of the premium if the underlying deal falls through. A useful mental model: forwards for certainty, options for uncertainty, and nothing for exposure so small or short-dated that the hedging cost exceeds the risk being managed. A machinery exporter bidding on a $2M tender might buy a 90-day option covering 50% of the bid value — if they win the tender, they exercise or roll the option into a forward; if they lose, the option expires and the only cost was the 1-2% premium, which is treated as a cost of doing business on bids.
Building the Hedge Ratio Discipline Month by Month#
A workable approach for an SME with recurring cross-border sales is a rolling hedge ladder rather than a single point-in-time decision. Each month, hedge a portion of the exposure expected to materialize in each of the next 6-12 months, with the hedge ratio increasing as the exposure becomes more certain — for example, 30% hedged at 12 months out, rising to 80% hedged at 1 month out as the forecast firms into confirmed orders. This smooths the average rate achieved over time rather than betting the entire year's exposure on a single day's rate. A furniture exporter with $3M in annual euro-denominated sales might run this ladder through forward contracts executed monthly, each covering a slice of the rolling 12-month forecast; the result is that no single quarter's results are dominated by a currency move that happened to occur right before a large unhedged shipment. The mistake to avoid is treating the ladder as static — it needs monthly rebalancing as sales forecasts change, and someone with clearly assigned authority (per the hedging policy) needs to execute it consistently rather than opportunistically. Businesses tracking multi-currency sales and exposure in one place can see the rolling forecast that should drive the hedge ladder instead of reconstructing it from scattered sales records each month.
Natural Hedging Before Reaching for Financial Instruments#
The cheapest hedge is one that costs nothing to execute, and many SMEs skip past natural hedging opportunities straight to forwards and options. A natural hedge exists when a company can match the currency of its costs to the currency of its revenue — an exporter selling into the EU who also sources a meaningful share of raw materials or components from EU suppliers can invoice customers in euros and pay suppliers in euros, letting the two flows offset each other without any financial instrument at all. A US-based apparel importer selling finished goods domestically but sourcing fabric from a European mill has a natural, partial hedge already built into its cost structure, whether or not it's ever formalized. Companies can deliberately expand this by shifting supplier relationships toward the currency zone of their strongest revenue exposure, holding a working cash balance in the foreign currency to cover near-term payables without conversion, or timing invoice currency choices to match cost currency wherever a customer is willing to accept it. None of this eliminates FX risk entirely — natural hedges are rarely a perfect match in timing or amount — but for an SME with limited treasury sophistication, maximizing the natural hedge before layering on forwards and options both lowers the cost of the hedging program and reduces the volume of financial instruments that need active management.
Currency Clauses as a Contractual Hedge#
Before reaching for a bank hedging instrument at all, some FX risk can be shifted or shared through the sales contract itself, a step many SMEs skip because it feels like a harder negotiating conversation than simply accepting the buyer's preferred currency. A price adjustment clause tied to a published exchange rate index lets a seller quote in the buyer's currency while automatically repricing if the rate moves beyond an agreed band — for example, a contract that holds the quoted price fixed for a 5% currency band but triggers a renegotiation or automatic adjustment if the rate moves further. Alternatively, some exporters negotiate shared-risk clauses that split any currency movement beyond a threshold between buyer and seller, which can be more palatable to a buyer than the seller unilaterally quoting a currency-risk premium into the base price. A capital goods exporter selling multi-year service contracts denominated in a volatile emerging-market currency might negotiate an annual repricing mechanism tied to a currency index specifically to avoid multi-year exposure sitting unhedged or requiring expensive long-dated forwards. These contractual tools don't replace financial hedging for large, near-term exposures, but for smaller or longer-dated exposures where forwards are expensive or unavailable, a well-drafted currency clause can meaningfully reduce the exposure that needs to be actively hedged at all.
