The short answer

Foreign exchange exposure is any way a change in exchange rates affects your business. Start by mapping it: list every foreign-currency cost, sale, loan and asset, with amounts and dates. Then measure it: work out what a 5% or 10% move would do to your profit. Then protect what matters: match foreign income with foreign costs where you can (natural hedging), fix known future payments and receipts with forward contracts, use limit and stop-loss orders for flexible timing, and set a budget rate for planning. Write it down in a short FX policy and review it monthly. Vita Capital, our FX and escrow partner, offers hedging and risk management for businesses, with a dedicated relationship manager.

Why currency moves matter so much

Currency moves matter because they hit profit, not just revenue. Consider a Thai business with ฿10 million of sales a year and a 10% profit margin — ฿1 million of profit. If ฿6 million of its costs are paid in US dollars, a 6% move against it adds ฿360,000 to those costs. That's more than a third of the year's profit gone, without selling a single item less.

And the baht can move that much in months. After rising strongly in 2025, it fell to a one-year low in June 2026 and a 15-month low in late July 2026. Businesses that had planned around the stronger baht found their import costs rising; exporters who had braced for a strong baht found their dollar income worth more.

The aim of managing exposure isn't to predict the market — nobody can do that reliably. It's to make your costs and income predictable enough that you can price, plan and grow with confidence.

The baht from 2025 to 2026

The last two years show how quickly conditions can change for Thai businesses. In 2025 the baht was strong: by September it was up about 8% for the year, one of Asia's best performers, after touching a four-year high, and it was trading around ฿31.88 to the dollar. Then it turned. In April 2026 it passed ฿32 to the dollar, a one-month low; in June it passed ฿33, a one-year low; and by late July it was around ฿33.8, a 15-month low.

An exporter who planned 2026 on 2025's strong baht would have been pleasantly surprised; an importer who did the same would have seen costs climb month after month. Neither could have known in advance — which is exactly why managing exposure is about certainty rather than prediction.

The three types of currency exposure

Most businesses have more than one.

A general guide to the main types of foreign exchange exposure.

Where currency risk hides in a business

Currency exposure turns up in more places than most owners expect. The obvious ones are imported stock and materials priced in dollars, yuan, yen or euros, one-off purchases of imported equipment, which can be large, and overseas services such as software subscriptions, consultants and marketing. Export sales invoiced in foreign currency and paid later carry exposure too, and so does tourism and hospitality income: prices are set in baht, but your customers' spending power depends on their own currency. Foreign loans, dividends and fees paid to foreign owners, and price lists or quotes fixed in one currency while costs are in another all add to it. Even your competitors' costs matter — if theirs are in a different currency, a move can shift prices across your market.

Mapping and measuring your exposure

You don't need complex software. A simple spreadsheet does the job:

1. List every foreign-currency flow — costs and income, by currency.
2. Add amounts and dates — for the next 3, 6 and 12 months.
3. Net them off — dollar income minus dollar costs gives your net dollar position.
4. Apply a stress test — what happens to profit if the baht moves 5% or 10% either way?
5. Compare with your tolerance — how much of a hit to profit could you absorb?
6. Decide what to protect — usually the large, known, near-term amounts first.

The result is a clear picture: which currencies matter, when, and how much is at stake. It's also exactly what an FX provider needs to recommend the right tools.

An exposure map in practice

Illustration only. "Short" means the business needs to buy the currency; "long" means it has more than it needs. The euro income partly offsets the dollar and yen costs — a natural hedge.

Natural hedging: the free protection

The simplest way to reduce exposure is to match foreign-currency income with foreign-currency costs, so a move in the rate affects both sides equally. Pay dollar suppliers from dollar income held in an FCD account, without converting twice, and consider invoicing in the currency of your costs — if your materials are in dollars, pricing exports in dollars keeps the two aligned. Borrow in the currency you earn, so loan repayments match income, and diversify your suppliers and markets so you're not dependent on one currency. It may also help to keep foreign income abroad: since January 2026, Thai residents' foreign-sourced funds under US$10 million no longer have to be brought back to Thailand, which makes it easier to pay foreign costs from foreign income. Ask your accountant how this applies to you.

Natural hedging costs nothing, but it rarely covers everything — which is where financial tools come in.

Where to start

Tools and expertise to protect your margins — and the right cover for your business.

The tools that protect your margins

Forward contracts

Fix today's rate for a payment or receipt on a future date. The workhorse of business FX: an importer agreeing a US$80,000 order payable in 90 days can fix the baht cost the day the order is signed. Our guide to forward contracts for importers and exporters explains them in detail.

Limit orders

Set a target rate and let the conversion happen automatically if the market reaches it — useful when you have flexibility on timing and want a better rate than today's.

Stop-loss orders

Set a rate at which you'll convert automatically if the market moves against you, capping how bad things can get.

Spot conversions

Convert at today's rate — simple and right for payments due now, but no protection for the future.

FCD accounts

Hold foreign currency in Thailand and choose when to convert, or pay foreign costs directly. Krungsri, for example, charges a 0.125% commission (minimum ฿1,000) when foreign currency is withdrawn to send abroad.

Structured contracts

For larger businesses, providers can design contracts that combine protection with some ability to benefit from favourable moves. Ask your FX provider to explain how any structure works before you agree to it.

How much to hedge

Few businesses hedge everything. A common approach is to hedge more of what's certain and near, and less of what's uncertain and far away: confirmed orders in the next three months are often fixed in full or close to it, expected orders three to six months out perhaps half, and forecasts six to twelve months out a smaller share, topped up as orders firm up.

This "layered" approach smooths out the rate you achieve over time, avoids betting everything on one day's rate, and leaves room to benefit if the market moves your way. The right percentages depend on your margins, your competitors and how much a currency move would hurt.

Writing a simple FX policy

An FX policy is just a page that sets out how your business handles currency. It stops decisions being made on hunches, and makes sure everyone — owners, managers and your accountant — is on the same page. It should state the objective (for example, “to protect gross margin on confirmed orders”), the currencies and flows it covers, and how much to fix and how far ahead. It should list the approved tools — for example, spot, forwards and limit orders only — and the budget rate used for pricing and planning. Finally, it should say who can deal and up to what limits, which providers you use, and when the policy is reviewed: monthly, and whenever there's a big market move.

Our guide to FX budgeting for Thailand-based businesses explains how to set and protect a budget rate.

Exposure by type of business

Importers and retailers

A weaker baht raises costs. Fix the cost of confirmed orders, and consider pricing in a way that can be adjusted if rates move sharply.

Exporters and manufacturers

A stronger baht reduces the baht value of sales. Fix the rate on confirmed export orders, and consider matching with imported materials.

Hotels, resorts and tourism

Income often arrives in euros, dollars or other major currencies from tour operators, while costs are in baht. Holding and converting foreign receipts carefully, and fixing rates on seasonal contracts, can make a real difference.

Service and tech businesses

Often paid by overseas clients in their currency, with staff paid in baht. Regular, predictable income is well suited to forward contracts or regular conversions.

Foreign-owned subsidiaries

Loans, management fees and dividends to the parent create exposure. Match currencies where possible and plan conversions in advance.

When the baht strengthens — and when it weakens

Who wins and who loses from a currency move depends on which side of it you're on.

A general guide. In 2025 the baht strengthened about 8% by September; by late July 2026 it had weakened to a 15-month low.

Pricing strategies that reduce currency risk

Hedging isn't only about financial contracts; how you price can shift or reduce currency risk too. Make quotes valid for a set time, so you're not committed to an old rate for months, and for long contracts agree a currency clause that adjusts prices if the rate moves beyond a set band. Invoicing in your cost currency keeps both sides aligned, and pricing on a slightly cautious budget rate means a modest move won't erase your margin. Review price lists regularly, especially after a big move in the baht, and when you agree a large order, fix the rate at the same time with a forward contract, so the margin you quoted is the margin you keep.

Working with your bank, accountant and FX provider

Managing exposure works best as a team effort. Your accountant can show how currency moves flow through your accounts, help with translation exposure and advise on tax. Your bank handles day-to-day payments and FCD accounts, and may offer trade finance. A specialist FX provider such as Vita Capital brings competitive rates, forward contracts, rate orders and market insights, with a dedicated relationship manager who gets to know your business. Share your exposure map and FX policy with all three, and meet at least once a year to review.

A simple monthly routine

Each month, update your exposure map with new orders, invoices and forecasts, and check your hedge levels against the targets in your FX policy. Book forwards for any newly confirmed orders, and review open limit and stop-loss orders to see whether the targets are still right. Compare the rates you actually achieved with the budget rate and note the effect on margins, read your provider's market update for anything that changes the picture, and send the owners a short note on exposure, hedges and results.

Once it's set up, this takes an hour or two a month — a small price for knowing your margins are protected.

Common mistakes

The most common mistake is ignoring exposure until it hurts, by which time the rate has already moved. The next is trying to predict the market: hedging is about certainty, not winning bets. Some businesses hedge more than they need, fixing amounts they may never actually pay or receive, while others forget the margin, even though a poor conversion rate on every payment adds up. Often no one is in charge — make one person responsible, with a written policy — and nobody reviews it, even though exposures change as the business does.

Three real-world examples

These are illustrations, not real businesses.

A Bangkok electronics importer

The importer pays about US$100,000 a month to suppliers. When the baht weakened from about ฿31.9 to ฿33.8 to the dollar, each month's costs rose by around ฿190,000. It now fixes the cost of confirmed orders with forward contracts as soon as they're agreed, and sets prices knowing its costs.

A Chiang Mai furniture exporter

The exporter invoices US customers in dollars. When the baht strengthened in 2025, its dollar income was worth less in baht. It now fixes the rate on large confirmed orders and buys some materials in dollars, so part of its exposure hedges itself.

A Krabi resort

The resort receives euros and other currencies from European tour operators months before guests arrive. It holds those receipts in an FCD account and uses limit orders to convert when rates reach its targets.

Your FX exposure checklist

• Net position by currency calculated.
• Impact of a 5% and 10% move tested.
• Natural hedges in place where possible.
• Forward contracts on confirmed orders.
• Limit or stop-loss orders where timing is flexible.
• A budget rate set for pricing and planning.
• A one-page FX policy agreed.
• Monthly review in the diary.

Questions to ask an FX provider

When you talk to a provider, ask how they would hedge your exposure and which tools they offer — forwards, limit and stop-loss orders, structured contracts. Ask what their rates are and how fees are included, whether they require a deposit or margin on forward contracts, and what happens if your payment date changes. Find out whether you'll have a dedicated contact, whether they provide market updates and alerts, and how client funds are protected.

Top tips

Map your exposure before you act, and aim to protect profit rather than chase the market. Start with natural hedges, which are free, then fix what's certain with forward contracts and layer your hedges over time. Write it all down in a one-page policy, review it monthly, and use a specialist with a dedicated contact.
