How Foreign Exchange Movements Can Affect Singapore SMEs

A Singapore SME does not need to operate an overseas office to be affected by foreign exchange movements.

A local business may buy inventory from a supplier in the United States, pay for software in US dollars, purchase machinery from Europe or receive payments from customers overseas.

Whenever money needs to be paid or received in another currency, changes in the exchange rate can affect the amount of Singapore dollars involved.

For a small transaction, the difference may be manageable.

For a large order, recurring supplier payments or a business operating on thin margins, the impact can become significant.

Foreign exchange risk should therefore be considered as part of normal pricing, budgeting and cash flow planning.

The aim is not to predict where currencies will move.

It is to understand how much the business could be affected if the exchange rate changes before payment takes place.

1. What is foreign exchange risk?

Foreign exchange risk arises when the value of one currency changes relative to another currency.

Consider a Singapore company buying goods from a supplier who invoices in US dollars.

Suppose the invoice is:

US$100,000

At a hypothetical exchange rate of:

US$1 = S$1.35

the Singapore dollar cost would be:

S$135,000

If the exchange rate changes before the company pays and becomes:

US$1 = S$1.40

the same US$100,000 invoice now costs:

S$140,000

The company needs another:

S$5,000

even though the supplier has not changed the invoice price.

The additional cost comes purely from the exchange rate movement.

2. Currency movements can affect import costs

Importers are one of the clearest examples of businesses exposed to foreign exchange movements.

A Singapore SME may purchase:

• Raw materials
• Finished products
• Machinery
• Spare parts
• Packaging
• Technology
• Equipment

from overseas suppliers.

If those suppliers invoice in foreign currencies, the final Singapore dollar cost can change between the date the order is placed and the date payment is made.

Consider another hypothetical example.

An SME places an order worth:

US$200,000

At:

US$1 = S$1.34

the expected cost is:

S$268,000

Before payment is made, the exchange rate changes to:

US$1 = S$1.39

The final cost becomes:

S$278,000

Difference:

S$10,000

If the company had budgeted exactly S$268,000, it now needs another S$10,000 of working capital.

3. Exchange rates can affect profit margins

The problem is not limited to cash flow.

Currency movements can also reduce the profit margin on a sale.

Suppose a Singapore distributor expects to sell imported goods for:

S$160,000

The expected supplier cost is:

S$120,000

Expected gross margin before other expenses:

S$40,000

Now imagine an unfavourable currency movement increases the supplier cost to:

S$130,000

The selling price remains unchanged.

The gross margin falls to:

S$30,000

The company has lost:

S$10,000

of expected margin without selling fewer units.

For businesses operating with relatively small margins, repeated currency movements can have a meaningful effect on profitability.

4. Exporters can also be affected

Foreign exchange risk works in both directions.

Suppose a Singapore SME sells services overseas and expects to receive:

US$80,000

At a hypothetical rate of:

US$1 = S$1.35

the payment would be worth approximately:

S$108,000

If the exchange rate changes to:

US$1 = S$1.30

before the customer pays, the same US$80,000 would be worth:

S$104,000

The company receives:

S$4,000 less

in Singapore dollar terms.

The customer has paid the full US$80,000.

Nothing is overdue.

However, the Singapore business receives less value when converting the foreign currency.

5. The timing between quotation and payment matters

Currency exposure can begin before an invoice is issued.

Imagine a Singapore SME gives a customer a quotation that remains valid for 90 days.

The selling price is fixed in Singapore dollars.

However, the business expects to purchase materials from an overseas supplier in US dollars.

When the quotation is prepared, the expected material cost is:

S$50,000

Two months later, currency movements increase the cost to:

S$54,000

If the customer has already accepted the fixed S$ price, the SME may need to absorb the additional S$4,000.

This is why businesses with foreign currency costs should think about exchange-rate exposure when preparing quotations, not only when the supplier invoice eventually arrives.

6. Longer payment periods can increase uncertainty

The longer the period between agreeing on a price and settling the payment, the more time there is for an exchange rate to change.

For example:

Day 1: Purchase order confirmed

Day 30: Goods produced

Day 45: Goods shipped

Day 60: Supplier invoice becomes payable

The business may have foreign exchange exposure throughout that period.

An SME should therefore understand:

• Which currency the payment will be made in
• When the amount becomes payable
• How long the exposure will remain
• How much the exchange rate could affect the final S$ cost

The purpose is not to forecast the exact future exchange rate.

It is to understand the potential range of outcomes.

7. Identify every currency the business is exposed to

A useful first step is creating a simple list of foreign currency exposures.

For example:

Currency	Expected Inflows	Expected Outflows	Main Reason
USD	US$40,000	US$150,000	Customers and suppliers
EUR	€0	€50,000	Equipment purchase
MYR	RM120,000	RM80,000	Customers and operating costs

This immediately gives management a clearer view of where the main exposure exists.

The company may discover that it receives some US dollars from customers but pays much larger amounts to US dollar suppliers.

Its main risk is therefore the remaining net US dollar requirement.

8. Focus on net exposure

Businesses should not always look at foreign currency inflows and outflows separately.

Suppose an SME expects during the next quarter:

US$100,000 of customer receipts

and:

US$160,000 of supplier payments

The business has both inflows and outflows in US dollars.

The simplified net requirement is:

US$160,000 – US$100,000 = US$60,000

If the timing allows the receipts to be used against the payments, the company may only need to convert enough Singapore dollars to cover the remaining US$60,000.

This is sometimes described as a form of natural hedging, where foreign currency inflows help offset foreign currency outflows.

However, the timing must match closely enough for this to work.

9. Matching currencies does not remove every risk

Suppose an SME receives US dollars from customers and also pays US dollar suppliers.

That may reduce the amount that needs to be converted.

However, problems can still occur if:

• Customers pay later than suppliers are due
• Customer receipts are smaller than expected
• Sales fall
• Supplier costs increase
• Payments occur in different months

For example:

Supplier payment due today: US$100,000

Customer receipt expected next month: US$100,000

The amounts match, but the timing does not.

The company may still need temporary liquidity to pay the supplier.

Foreign exchange planning therefore needs to consider both currency and timing.

10. Build exchange-rate sensitivity into the budget

Instead of assuming one exchange rate will remain unchanged, SMEs can test several hypothetical rates.

Suppose the business expects to pay:

US$100,000

The budget might test:

Hypothetical Exchange Rate	S$ Cost
US$1 = S$1.30	S$130,000
US$1 = S$1.35	S$135,000
US$1 = S$1.40	S$140,000
US$1 = S$1.45	S$145,000

The business can immediately see that between S$1.30 and S$1.45, the S$ cost differs by:

S$15,000

Management can then ask:

Could the business absorb the higher cost without disrupting normal operations?

This is more useful than assuming the current exchange rate will definitely remain unchanged.

11. Test the effect on profit as well as cash

Suppose an importer expects:

Sales revenue: S$250,000

and:

Foreign currency supplier cost at budgeted rate: S$180,000

Expected amount before other expenses:

S$70,000

Now test a currency movement that raises the supplier cost by:

S$12,000

The amount remaining falls to:

S$58,000

The company can then consider whether:

• The margin remains acceptable
• Prices need reviewing
• Costs can be reduced elsewhere
• Future quotations require a larger buffer

Foreign exchange exposure should therefore form part of both cash flow forecasting and margin analysis.

12. Be careful when giving customers long fixed-price quotations

An SME may quote a customer in Singapore dollars while its own costs remain exposed to foreign currency movements.

This creates a mismatch.

The customer’s price is fixed.

The supplier cost is not.

Depending on the business and contract, management may consider measures such as:

• Shorter quotation validity periods
• Reviewing prices before large orders are confirmed
• Building a reasonable currency buffer into pricing
• Agreeing how major cost changes will be handled where commercially appropriate

The exact approach depends on the customer relationship and contract.

The important point is to understand who carries the currency risk after the selling price has been agreed.

13. Deposits can reduce some timing exposure

Depending on the business model, requesting an appropriate customer deposit may help reduce the amount of money the company needs to fund before completing an order.

Suppose an SME accepts a large project requiring foreign currency purchases.

If the business pays the overseas supplier before receiving any money from the customer, it carries the full initial cash requirement itself.

A customer deposit may reduce that working capital gap where deposits are commercially appropriate.

However, a deposit does not automatically remove foreign exchange risk.

If the supplier payment occurs later and the currency changes significantly, the remaining project cost may still be affected.

14. Foreign exchange movements can increase working capital needs

Currency risk and working capital are closely connected.

Consider an importer expecting to pay:

US$300,000

At:

US$1 = S$1.35

expected payment:

S$405,000

If the rate moves to:

US$1 = S$1.40

the payment becomes:

S$420,000

Additional cash required:

S$15,000

If the company is already operating with tight working capital, that S$15,000 difference may affect its ability to pay:

• Salaries
• Other suppliers
• Rent
• GST
• Financing repayments
• Other operating expenses

The currency movement does not need to make the underlying transaction unprofitable to create short-term cash pressure.

15. Growth can increase foreign exchange exposure

A growing importer may become more exposed even if the exchange rate itself becomes no more volatile.

Suppose a business originally imports:

US$50,000 per month

After expansion, purchases rise to:

US$250,000 per month

A small exchange-rate movement now affects a much larger transaction amount.

For example, a movement that changes the S$ cost by:

S$0.03 per US dollar

would affect:

US$50,000 × S$0.03 = S$1,500

at the old purchase volume.

At the new volume:

US$250,000 × S$0.03 = S$7,500

The company’s currency exposure has grown because the business itself has grown.

Foreign exchange management may therefore deserve more attention as overseas purchasing or sales become larger.

16. Do not assume currencies will move in your favour

A common mistake is delaying a currency decision because management believes the exchange rate will improve.

For example:

“Let’s wait another week. The US dollar might become cheaper.”

It might.

It might also become more expensive.

Unless the business is deliberately taking a speculative position, its objective should usually be managing the commercial transaction rather than trying to predict short-term currency markets.

A budget should be built around what the company can afford, not around hoping for a favourable exchange-rate movement.

17. Understand what currency hedging is trying to achieve

Currency hedging is generally used to reduce uncertainty around future foreign currency transactions.

Singapore is a major foreign exchange centre, and financial institutions provide various foreign exchange and hedging solutions for businesses.

One commonly discussed tool is a forward contract.

In simplified terms, a forward allows a business to agree an exchange rate for a future currency transaction, subject to the terms of the arrangement.

The purpose is greater certainty.

Suppose a business knows it will need US dollars in three months.

Without hedging, the final S$ cost depends on the exchange rate at that future date.

With an appropriate forward arrangement, the business may be able to lock in a rate for the planned transaction.

DBS, for example, currently offers business FX services that allow eligible customers to book future FX rates, illustrating that this type of risk-management tool is available in Singapore.

18. Hedging does not mean getting the best possible exchange rate

A hedge is intended to reduce uncertainty.

It does not guarantee that the business will end up with the most favourable rate that later becomes available.

Suppose an SME locks in a future exchange rate.

If the currency later moves against the company, the agreed rate may protect the budget.

If the currency later moves in the company’s favour, the business may not receive the full benefit of that favourable movement under the hedging arrangement.

This is the trade-off.

The objective is usually predictability, not beating the foreign exchange market.

Businesses should also understand the terms, costs and obligations of any hedging product before using it.

19. Not every SME needs a complex hedging strategy

A company with occasional foreign currency purchases may not require the same approach as an importer paying overseas suppliers every week.

The level of attention should reflect the size and importance of the exposure.

Management could consider:

• How much foreign currency is involved
• How often transactions occur
• How long the exposure remains open
• How sensitive profit margins are
• How much working capital the company has
• Whether foreign currency inflows offset outflows

For a small exposure, maintaining a reasonable cash buffer may be sufficient.

For a large recurring exposure, the company may want to discuss foreign exchange risk management options with its bank or a suitably qualified adviser.

The response should be proportional to the business risk.

20. Keep an FX exposure schedule

A simple schedule can make foreign exchange requirements easier to manage.

For example:

Payment Date	Currency	Amount	Purpose	Status
15 September	USD	US$70,000	Inventory	Confirmed
30 September	EUR	€25,000	Equipment	Confirmed
20 October	USD	US$40,000	Supplier payment	Forecast
5 November	MYR	RM90,000	Operating cost	Forecast

Management can then see:

• Which currencies are required
• How much is required
• When the payment is expected
• Which amounts are confirmed
• Which are still forecasts

This is much easier to manage than discovering a large foreign currency payment only when the supplier invoice becomes urgent.

21. Connect foreign exchange planning with cash flow forecasting

Foreign exchange exposure should not sit in a separate spreadsheet that nobody connects to the main cash forecast.

Suppose the business expects a US$100,000 supplier payment in November.

Its cash flow forecast should not simply show:

Supplier payment: S$135,000

and assume that figure is guaranteed.

Management might instead budget using a central assumption while also testing an unfavourable exchange-rate scenario.

For example:

Budgeted cost: S$135,000

Stress scenario: S$142,000

The business can then understand whether another S$7,000 would create a liquidity problem.

This connects currency risk directly to working capital planning.

22. Review customer and supplier currencies together

Some businesses may have flexibility over which currencies they use commercially.

For example, a company may receive revenue in one currency while most of its costs are in another.

Management can review whether the currency structure itself creates unnecessary exposure.

Questions may include:

• Which currencies do customers pay us in?
• Which currencies do suppliers require?
• Can some inflows naturally support outflows?
• Are we converting the same currency multiple times?
• Are foreign currency balances building up without a clear purpose?

The most efficient structure depends on the individual business and commercial agreements.

The goal is to understand the currency flows rather than allowing them to develop without oversight.

23. Review foreign exchange exposure before accepting a major contract

A large overseas contract can appear attractive based on revenue alone.

However, management should consider the currency exposure before committing.

For example:

Contract revenue: US$500,000

The company may have:

• Costs in Singapore dollars
• Supplier costs in US dollars
• Staff expenses in Singapore dollars
• Customer payment several months later

Before accepting the project, management can test what happens to expected profit under different exchange rates.

If a relatively small currency movement removes most of the expected margin, the commercial terms may need more careful review.

A large contract should not automatically be treated as a safe contract.

24. Consider foreign exchange risk when borrowing

Financing can also interact with currency exposure.

Suppose a business takes financing in Singapore dollars to pay an overseas supplier in US dollars.

The financing amount may be based on the expected exchange rate.

If the foreign currency becomes more expensive before the supplier is paid, the original financing amount may no longer cover the full purchase.

For example:

Expected supplier cost: S$200,000

Financing arranged: S$200,000

Actual cost after currency movement:

S$208,000

The business now needs another:

S$8,000

from its own working capital.

When financing is linked to an overseas purchase, the currency assumption should therefore be included in the funding plan.

25. Financing should not become a substitute for managing recurring FX risk

A business may occasionally need additional working capital because an unexpected currency movement increased the cost of an important order.

That is different from repeatedly borrowing because management never plans for foreign exchange exposure.

If currency-related cash shortages occur frequently, the company should investigate:

• Whether pricing reflects the risk
• Whether cash buffers are sufficient
• Whether customer payment terms create too much exposure
• Whether supplier terms can be improved
• Whether natural currency offsets exist
• Whether suitable hedging should be considered

Financing may help manage a temporary liquidity gap.

It does not remove the underlying exposure.

26. Questions SME owners should ask

Before entering a significant foreign currency transaction, management can ask:

Which currency are we exposed to?

Identify the actual foreign currency requirement.

How much money is involved?

A small exchange-rate movement matters more when the transaction is large.

When will the payment or receipt occur?

Longer periods create more time for rates to change.

Is the selling price already fixed?

Understand whether an unfavourable currency movement can be passed on or must be absorbed.

What happens to our profit if the exchange rate moves by 5%?

Test the margin rather than looking only at revenue.

What happens to working capital?

Calculate the additional S$ cash required.

Do we have foreign currency inflows that can offset the payment?

Look at net exposure.

Does the timing of those inflows match?

Equal amounts in different months may not solve the cash flow problem.

Should we maintain a larger buffer?

Not every exposure requires a financial product.

Is hedging appropriate for this transaction?

Consider the size, frequency and certainty of the exposure.

Do we understand the hedging terms?

Do not use a financial product simply because it sounds protective.

Does our cash flow forecast include an unfavourable currency scenario?

Foreign exchange risk should be visible before the payment becomes urgent.

Final thoughts

Foreign exchange movements can affect Singapore SMEs in ways that are easy to underestimate.

A business may agree on a profitable sale today and discover several weeks later that the cost of its overseas supplier has increased in Singapore dollar terms.

An exporter can experience the opposite problem when foreign currency revenue converts into fewer Singapore dollars than expected.

The underlying sale may not have changed.

The currency value has.

For SMEs buying from or selling to overseas markets, foreign exchange risk should therefore be included in pricing, margin analysis and cash flow planning.

Businesses can begin with simple steps such as identifying foreign currency exposures, tracking payment dates, focusing on net currency requirements and testing how different exchange rates would affect profit and working capital.

Larger or recurring exposures may justify considering additional risk-management options, including suitable foreign exchange hedging arrangements. Singapore’s financial market provides businesses with access to such tools, although the appropriate approach depends on the company’s exposure, financial position and the terms of the product.

The objective is not to predict currencies perfectly.

It is to make sure an exchange-rate movement does not turn an otherwise healthy business transaction into an unexpected cash flow problem.
