What is FX risk management?

There are three main kinds of exposure. Transaction exposure arises from invoices, payments and forecast cash flows in foreign currencies. Translation exposure arises when foreign subsidiaries' results are converted into the group's currency for reporting. Economic exposure is the longer-term effect of rates on competitiveness. Treasury collects exposures from the ERP, forecasts, bank balances and intercompany loans, nets offsetting positions, and hedges the rest under a policy that sets which exposures to cover and how far ahead. Forwards fix a rate for a future date; options cap the downside for a premium. Hedge accounting under IFRS 9 or ASC 815 can match hedge gains and losses with the hedged item, but requires documentation and effectiveness testing. Embat consolidates FX exposures from the ERP, forecasts and bank balances and flags breaches of hedging limits.

Transaction exposure is the easiest to quantify because the ERP already holds it. Open accounts payable and receivable, grouped by currency and due date, show the amounts that will settle in foreign currency. Purchase orders, sales orders and contracts add committed flows that have not yet been invoiced, and bank balances and intercompany loans add cash and financing positions. Treasury nets receivables against payables in each currency and reports the remainder by maturity bucket, so each bucket can be compared with the hedges already in place.

Translation exposure is measured from subsidiary balance sheets. For each entity whose functional currency differs from the group's presentation currency, treasury takes net assets from the consolidation ledger. Under IAS 21, assets and liabilities of a foreign operation are translated at the closing rate and income and expenses at transaction date rates, with an average rate often used as a practical proxy. The resulting differences are recorded in other comprehensive income. A euro group with a US subsidiary holding USD 10 million of net assets, for example, carries about EUR 9.09 million of exposure at a rate of 1.10 dollars per euro. A 5% fall in the dollar would cut that value by about EUR 0.45 million.

Economic exposure cannot be read directly from the ledger. Finance teams estimate it by splitting forecast revenue and costs by currency from ERP and planning data, then testing how margins would change under rate scenarios. A business that sells in dollars but pays most costs in euros is exposed even if no dollar invoice is open today. Because the figure rests on forecasts, treasury usually reviews it alongside the budget cycle rather than daily.

A forward contract commits both sides to exchange a set amount of currency at an agreed rate on a future date. It removes uncertainty and costs nothing upfront, but the buyer gives up any gain if the market moves in their favour. An option gives the buyer the right, not the obligation, to exchange at a strike rate. The buyer pays a premium for that protection and keeps the benefit of a favourable move. A swap exchanges currency flows over time. An FX swap pairs a spot exchange with an opposite exchange on a later date, and is often used to roll a hedge forward when a payment slips. A cross-currency swap exchanges interest payments and principal in two currencies, and is used mainly to hedge foreign currency debt.

Worked example. A mid-sized euro-based importer must pay a supplier USD 2,000,000 in 90 days. The spot rate is 1.1000 dollars per euro, which puts the cost today at EUR 1,818,182. The figures below are illustrative, not market quotes.

Forward: the importer buys USD 2,000,000 for delivery in 90 days at 1.1050. The cost is fixed at EUR 1,809,955 whatever the market does. If the dollar strengthens to 1.0500, an unhedged payment would cost EUR 1,904,762, so the forward saves EUR 94,807. If the dollar weakens to 1.1500, an unhedged payment would cost EUR 1,739,130, and the importer pays EUR 70,825 more than the market rate.

Option: the importer buys a dollar call with a strike of 1.1000 and pays a premium of EUR 20,000. If the dollar strengthens to 1.0500, the option is exercised at 1.1000, and the total cost is EUR 1,838,182 including the premium. If the dollar weakens to 1.1500, the option lapses, the importer buys dollars in the market for EUR 1,739,130, and the total cost is EUR 1,759,130 including the premium. The worst case is capped, and the premium is the price of keeping the upside.

Most treasury policies also set a hedge ratio and a horizon, for instance covering a stated share of forecast flows for the next several months, and reduce the share as the forecast period lengthens and the forecast becomes less certain.

Derivatives are carried at fair value, so without hedge accounting a forward's gain or loss reaches profit before the hedged payment does. Hedge accounting removes that mismatch. In a cash flow hedge of a forecast purchase, the effective part of the derivative's change in value is held in other comprehensive income and moved to profit when the hedged item affects earnings. In a fair value hedge of a recognised item, both the derivative and the hedged item are remeasured through profit. A net investment hedge covers a foreign subsidiary's net assets, with the effective part recorded in other comprehensive income.

IFRS 9, set out on the IFRS Foundation's IFRS 9 page, requires that the hedging instrument and hedged item are eligible, and that the relationship is formally designated and documented at inception, including the risk management objective and strategy. There must be an economic relationship between the hedged item and the instrument, credit risk must not dominate the value changes, and the hedge ratio must reflect the quantities actually used. IFRS 9 replaced the 80 to 125 percent test of IAS 39 with these principle-based criteria, and requires the hedge ratio to be rebalanced if the relationship drifts while the objective is unchanged.

ASC 815 also requires documentation at inception of the hedging relationship, the risk management objective and strategy, the hedged item, the risk hedged and the method used to assess effectiveness. The hedge must be highly effective. ASU 2017-12 allows ongoing effectiveness assessments to be qualitative when certain conditions are met, and gives extra time to complete the initial quantitative assessment. It also removed the separate measurement of ineffectiveness for cash flow hedges.

Auditors typically test that the designation memo exists and was prepared on time, that a hedged forecast transaction is highly probable, that the terms of the derivative match the hedged item, that effectiveness or economic relationship assessments support the chosen method, that derivative fair values are correct, and that amounts held in other comprehensive income are released in the right period. They also check that disclosures describe the hedging strategy and its effect on the financial statements.
