Why operational foreign exchange risk affects almost every Swiss SME
The Swiss franc (CHF) is a strong and stable currency, but that does not automatically protect SMEs that buy raw materials in euros, sell services in dollars, or pay software licence fees in sterling. Operational foreign exchange risk — also known as transaction risk — arises when costs and revenue are denominated in currencies other than the reporting currency, or when receipts and payments occur at different times from when the price is set.
Unlike financial foreign exchange risk (linked to loans or investments in foreign currency), operational risk directly affects the gross margin of each individual commercial transaction. A 3% weakening of the CHF on a EUR purchase equivalent to CHF 200'000 can erode CHF 6'000 of margin — without sales volume changing in the slightest.
This guide explains how to identify foreign-exchange exposure in current operations, quantify its economic impact, and define an FX management policy suited to the size and risk profile of a Swiss SME, with reference to accounting under Swiss standards (Swiss GAAP FER).
Where foreign-exchange exposure hides
Operational risk is not limited to exporting companies. In Swiss practice, exposure emerges in at least four recurring situations:
Purchases in foreign currency
Raw materials, components, goods, or services invoiced in EUR, USD, or GBP. The cost in CHF varies between the order, receipt of goods, and payment — often with a gap of weeks or months.
Sales in foreign currency
Invoices issued in EUR or USD to foreign customers. If the price is fixed in foreign currency but costs are in CHF, a strengthening franc reduces effective revenue at the time of collection.
Timing mismatch
Risk materialises between the economic accrual date (order, invoice, delivery) and the settlement date (payment or receipt). The longer the cycle, the greater the exposure.
Exchange-indexed pricing
Price lists updated quarterly or contracts with FX adjustment clauses. Monitoring is still required: the clause may not cover the full variance or may trigger with a delay.
Impact on margin: concrete examples for an SME
The figures below illustrate how moderate exchange-rate movements affect typical transactions. An initial EUR/CHF rate of 0.94 is assumed:
| Scenario | Transaction | EUR/CHF at 0.94 | EUR/CHF at 0.91 (−3.2%) | Impact on margin |
|---|---|---|---|---|
| Importer | Purchase goods EUR 100'000, sale CHF 115'000 | Cost CHF 94'000 — margin CHF 21'000 | Cost CHF 91'000 — margin CHF 24'000 | +CHF 3'000 (CHF strengthens) |
| Importer | Same purchase, CHF weakens to 0.97 | Cost CHF 94'000 — margin CHF 21'000 | Cost CHF 97'000 — margin CHF 18'000 | −CHF 3'000 (CHF weakens) |
| Service exporter | Invoice EUR 50'000, costs CHF 40'000 | Revenue CHF 47'000 — margin CHF 7'000 | Revenue CHF 45'500 — margin CHF 5'500 | −CHF 1'500 |
| Mixed supplier | 60% costs in CHF, 40% in EUR — 100% revenue in CHF | Stable gross margin in the short term | Partial erosion on the 40% exposed portion | Depends on currency mix |
The cumulative effect over a financial year can be significant: an SME with CHF 500'000 in annual EUR purchases and an average variance of 2% records CHF 10'000 of cost variation — often without management noticing until quarter-end close.
Mapping exposure: the first operational step
Before hedging the risk, you need to quantify it. Effective mapping starts from accounting and commercial data already available:
Currency inventory
List all suppliers and customers invoiced in foreign currency. For each, note the currency, estimated annual volume, payment terms, and order frequency.
Net balance calculation by currency
For each currency, subtract outflows (purchases, costs) from inflows (sales, receipts). A negative net balance in EUR means the SME is short EUR and suffers if the CHF weakens.
Maturity analysis
Break down foreign-currency receivables and payables by maturity bucket (0–30, 31–60, 61–90, over 90 days). Short-term exposure is what affects margins in the next quarter.
Materiality threshold
Define a threshold above which an exchange-rate movement significantly affects results. For many SMEs, a 1–2% variance on a net exposure above CHF 100'000 justifies a structured response.
Risk management and hedging instruments
Swiss SMEs have a range of instruments, from the simplest to the most sophisticated. The choice depends on exposure size, expected volatility, and internal expertise:
| Instrument | Mechanism | Advantages | Limitations |
|---|---|---|---|
| Natural hedge | Align cost and revenue currencies (e.g. both purchases and sales in EUR) | No financial cost, no derivative contract | Rarely perfect; requires negotiation with commercial partners |
| Invoicing in CHF | Transfer risk to the customer/supplier by requesting prices in francs | Transfers risk to the other party | May reduce competitiveness or increase purchase costs |
| Forward (outright forward) | Contract with the bank for a fixed rate on a future date | Predictable margins, full protection on the hedged amount | Obligation to execute; no benefit if the exchange rate moves favourably |
| Currency option | Right (not obligation) to buy/sell at a preset rate | Downside protection with upside if the exchange rate is favourable | Upfront premium; higher cost than a forward |
| Contractual clauses | Price revision if the exchange rate exceeds a threshold (e.g. ±3%) | Flexible, negotiable case by case | Depends on bargaining power; activation is not automatic |
| Foreign-currency accounts | Hold EUR/USD liquidity to pay suppliers without converting | Reduces frequent conversions and fees | Exposes the balance to exchange-rate risk until used |
Defining an FX management policy
A written policy — even one page — avoids reactive and inconsistent decisions. For a Swiss SME, an effective structure includes these elements:
Objective
Establish whether the company aims for maximum margin predictability (high hedging) or accepts a share of risk in exchange for flexibility and lower financial costs.
Example: "Hedge at least 70% of net EUR exposure with maturity within 90 days."
Responsibilities
Specify who monitors exchange rates (CFO, accounting, owner), who approves hedging transactions, and how often the exposure report is updated.
In smaller SMEs, the owner and fiduciary may share quarterly monitoring.
Authorised instruments
Explicitly list permitted instruments (forwards, simple options) and excluded ones (speculation, high leverage, cryptocurrencies).
Swiss banks, under FINMA supervision, offer regulated products; avoid opaque or undocumented instruments.
Limits and reporting
Set a maximum unhedged exposure amount, a time horizon for forward transactions, and a monthly or quarterly report for the management board.
The report should show gross and net exposure by currency, active hedges, and the estimated impact of a 1% and 3% exchange-rate movement.
Accounting in Switzerland: FER, exchange differences, and derivatives
Under the Swiss Code of Obligations (CO, art. 957a et seq.) and Swiss accounting standards (Swiss GAAP FER), foreign-currency transactions are converted at the exchange rate prevailing on the transaction date. Monetary receivables and payables in foreign currency are remeasured at the closing rate on the balance sheet reference date.
Exchange differences realised (at payment or receipt) flow through the income statement, generally within financial result. Unrealised differences on monetary items follow the prudence principle: losses are normally recognised in profit or loss, while unrealised gains may be deferred until realisation through provisions.
Hedging instruments (forwards, swaps, options) must be recognised and measured at fair value. SMEs using simple forwards to hedge identifiable commercial flows may, in certain cases and under Swiss GAAP FER 27, apply hedge accounting that reduces income statement volatility. Documenting the relationship between the instrument and the underlying flow is essential — both for the audit and for the bank.
For tax purposes, realised exchange differences are generally taxable or deductible. For unrealised differences on monetary items, the prudence principle applies; where functional currency accounting is used, specific conversion rules under federal tax law may apply. The fiduciary or auditor can confirm the treatment applicable to each case.
Six-step action plan for your SME
A practical path to integrate foreign exchange risk management into day-to-day operations, without overhauling the organisation:
Extract data from accounting
Filter purchase and sales invoices by currency over the last 12 months. Accounting software such as Accountex lets you analyse flows by currency and supplier/customer, quickly identifying areas of exposure.
Calculate quarterly net exposure
Update the net balance by currency at each quarter-end. Compare exposure against budget and flag variances above the defined threshold.
Align prices and commercial terms
Renegotiate price lists or revision clauses with key partners. Even a partial adjustment reduces residual exposure to be covered with financial instruments.
Activate targeted hedges with the bank
For net exposure not absorbed by natural hedging, request forward quotes at 30, 60, or 90 days. Compare the implicit cost (rate spread) with potential margin erosion.
Integrate monitoring into management reporting
Include in the monthly report for management: exposure by currency, average hedge ratio, period exchange differences, and simulated impact on gross margins.
Review the policy annually
At year-end, assess whether the policy protected margins as expected, whether the materiality threshold is still appropriate, and whether the instrument mix should be adjusted to reflect business evolution.
Common mistakes to avoid
Ignoring small recurring exposures
Even monthly invoices of EUR 5'000–10'000 generate meaningful annual exposure. The cumulative effect matters more than any single amount.
Hedging too much or too little
100% hedging on uncertain exposures locks in forgone margin if the exchange rate moves favourably. Conversely, hedging nothing with net exposure above CHF 200'000 amounts to an undeclared bet.
Confusing operational and financial risk
A EUR loan and a EUR goods purchase require different logic. The first concerns debt service; the second concerns commercial margin. Do not combine them in the same report without distinguishing them.
Forgetting bank fees
Spreads, conversion fees, and forward costs reduce the benefit of hedging. Include them in the break-even calculation against unhedged exposure.
Conclusion: exchange rates as a management variable, not a surprise
Operational foreign exchange risk is not a topic reserved for large multinationals. Every Swiss SME that buys or sells in foreign currency — even occasionally — exposes its margins to movements that fall outside traditional commercial control.
Combining regular exposure mapping, a proportionate hedging policy, and correct accounting turns exchange rates from a source of surprises into a monitored management variable. Integrated accounting tools, currency reports, and impact simulations make this process accessible even to businesses with few staff.
Starting with an analysis of flows over the last 12 months and a materiality threshold agreed with your fiduciary is the fastest way to understand whether your margins are protected — or whether a significant share of results depends on currency movements that nobody is tracking.
