Is a weaker dollar always good for exporters?
When the dollar weakens, commentators often say U.S. multinationals will benefit, because the same euro or yen of foreign sales converts into more dollars. But companies that buy inputs in foreign currencies, carry foreign debt, or hedge their exposure may see a smaller effect, or even the opposite.
This post walks through how currency moves reach company results, how to separate revenue and cost currencies, and how transaction and translation effects differ, using a hypothetical company. It also covers where to find hedging and sensitivity disclosures.
How currency exposure arises
Exchange rates affect companies through three main channels. Foreign-currency revenue and costs change value when converted into the reporting currency. Foreign-currency assets and liabilities, such as receivables or borrowings, are revalued, producing currency gains or losses. And the results and net assets of foreign subsidiaries change when translated.
IAS 21 sets out how foreign-currency transactions and foreign operations are translated into functional and presentation currencies; U.S. GAAP has equivalent rules. As a result, the same currency move can show up partly in operating profit, partly in non-operating items, and partly directly in equity through other comprehensive income.
Separating revenue and cost currencies
To gauge the effect, you need the foreign-currency share of both revenue and costs. If most revenue and most costs are in the same foreign currency, gains on one side are largely offset on the other. If revenue is foreign but costs are mostly domestic, the effect is amplified.
The table models a hypothetical U.S. company with €400 million of revenue, €250 million of euro-denominated costs, and $100 million of dollar costs, at three EUR/USD rates.
| EUR/USD | Revenue in $ | Euro costs in $ | Dollar costs | Operating profit | Vs. 1.10 |
|---|---|---|---|---|---|
| 1.00 | 400 | 250 | 100 | 50 | -23% |
| 1.10 | 440 | 275 | 100 | 65 | - |
| 1.20 | 480 | 300 | 100 | 80 | +23% |
A roughly 9% move in the euro changes operating profit by 23%. Because some costs are fixed in dollars, the currency effect is magnified in profit.
Transaction and translation effects
Transaction effects arise when foreign currency actually changes hands. If the euro strengthens between booking a sale and collecting payment, the company records a currency gain. Translation effects arise when foreign-currency balances are remeasured at period-end rates, and they appear in results even though no cash moves.
A company with large foreign-currency borrowings can see operating profit improve from a currency move while net income falls because of losses on remeasuring that debt. That is why operating and non-operating currency effects should be examined separately.
Reading the hedging disclosures
Many companies reduce currency risk with forward contracts or currency swaps. Hedging locks in exchange rates, giving up part of the benefit when currencies move favorably in return for protection when they move unfavorably.
IFRS 7 requires a sensitivity analysis for currency risk, and U.S. companies disclose market risk in Item 7A of the 10-K. These disclosures often state how much pre-tax income would change if exchange rates moved by 10%, along with details of derivative contracts. They usually describe a company's real exposure more accurately than a back-of-the-envelope estimate.
Sensitivity and timing
Currency effects may not appear immediately. Long-term contracts with fixed prices reflect new rates only when they are renewed, and hedges apply the old rates until they mature.
If a currency move persists, competitors may adjust their prices and imported input costs may rise, eroding the initial benefit. Currency effects are best judged by how results evolve over several quarters rather than one.
What to check in the 10-K
Using the 10-K and 10-Q on EDGAR, work through these steps for a company you follow.
- Find revenue by geography and the share earned outside the home market.
- Look for where key inputs are purchased and in which currencies, and the share of overseas production.
- Read Item 7A for the company's currency sensitivity and its foreign-currency assets and liabilities.
- Check the derivatives note for the size and maturity of currency hedges.
- Track currency gains and losses in non-operating income quarter by quarter, and note constant-currency growth if the company reports it.
Limits of currency analysis
Exchange rates are hard to forecast, and whatever moves them, such as interest-rate gaps, growth, or geopolitical events, also affects demand and costs. An effect calculated for currency alone can differ from what actually happens.
The company in the table is hypothetical. For real analysis, use the sensitivity disclosures in the latest filings with their revision dates in mind, and rely on the exposure a company reports about itself before headlines about currency winners and losers.
