The short answer

If your pension is paid in pounds and you live in Thailand, every move in the exchange rate changes your income. Protect it in five ways: keep one to two years of spending in baht so you're never forced to convert at a bad moment; convert regularly at a good rate — DWP's 0.39% on the State Pension, a low-cost provider or an FX specialist rather than a high-street bank; fix the rate for a year's income with a forward contract when you want certainty; keep some long-term savings in other currencies; and budget with headroom, especially above the ฿65,000 visa income level. Lawrence offers a free review to build an income plan that copes with a weaker pound.

How currency moves hit pension income

Take a retiree with £2,000 a month of pension income. At ฿70 to the pound, that's ฿140,000 a month. At today's rate of around ฿44.38, it's ฿88,760. At ฿40, it would be ฿80,000. Same pension, same pounds — very different lives in Thailand.

Three things make pension income particularly exposed:

• It's regular and fixed — you need a certain amount of baht every month, whatever the rate.
• The State Pension is frozen — there are no yearly increases to offset a weaker pound.
• Costs rise in baht — rent, food and healthcare in Thailand increase over time, while the pound may not keep pace.

Currency moves also come at awkward times. A sharp fall in the pound often coincides with turbulence in markets and uncertainty at home, just when retirees feel least like making big decisions. Having a plan in place beforehand — a buffer, regular transfers and a budget with headroom — means you can sit tight rather than react.

Unlike a working expat, a retiree usually can't simply earn more when the pound falls. That's why planning matters: the aim is a retirement income that remains comfortable at a weaker rate, not just at today's.

The hidden cost: how you convert

Nobody can control the exchange rate. But you can control what you pay to convert — and over a retirement, that adds up to a surprising amount.

UK banks' exchange-rate margins are reported at around 1% to 3.55%. On £24,000 of pension income a year, a 3% margin costs £720 every year — £14,400 over 20 years. A 1% margin costs £4,800 over the same period. DWP's 0.39% charge on a State Pension paid into a Thai account would cost about £1,872.

The practical lessons:

• State Pension: DWP's 0.39% conversion into a Thai account is competitive, and simple.
• Private pension income: avoid converting through a high-street bank; use a low-cost provider or an FX specialist.
• Larger sums — a year's income, tax-free cash — get a specialist quote; on big amounts the rate matters far more than the fee.
• Compare the baht that arrive, not the advertised fee.

Currency and your retirement visa

For many retirees, currency risk has a second dimension: the visa. A retirement extension typically needs ฿800,000 in a Thai bank account, an income of at least ฿65,000 a month, or a combination. If you rely on the income route, the pounds you need depend on the exchange rate.

At ฿44.38 to the pound, ฿65,000 a month needs about £1,465 of income. At ฿40, it needs £1,625; at ฿38, about £1,711. A full new State Pension of £241.30 a week — roughly ฿46,500 a month today — isn't enough on its own, and a weaker pound widens the gap.

Two common solutions: keep your income comfortably above the threshold, so a fall in the pound doesn't push you below it; or use the ฿800,000 deposit route, which, once in baht, isn't affected by exchange rates. Some retirees combine the two.

Five ways to protect your pension income

1. Keep a baht buffer

Hold one to two years of spending in a Thai account. When the pound is weak, live off the buffer and wait; when it's strong, top the buffer up. A buffer turns a currency crisis into a minor inconvenience.

2. Convert regularly

Monthly or quarterly transfers average out the rate over time, so you never put a whole year's income through on one bad day. Automated regular payments make it effortless.

3. Fix the rate for the year ahead

A forward contract lets you fix today's rate for transfers up to a year or more ahead. You lose the benefit if the pound rises — but you gain certainty about exactly how many baht you'll have to live on, which many retirees value far more.

4. Hold some savings in other currencies

If all your wealth is in pounds, all of it moves with the pound. Holding some long-term savings in a global portfolio — much of it in dollars and other currencies — spreads the risk, so a weak pound hurts less.

5. Budget with headroom

Plan your spending at a slightly weaker rate than today's — say ฿40 rather than ฿44 — so a fall in the pound doesn't force cuts. If the pound holds up, the extra is a bonus.

Where to start

The right way to convert your pension income, and someone to plan it with you.

Fixing the rate: how a forward works for a retiree

A forward contract is simply an agreement with an FX provider to exchange a set amount of money at a fixed rate on one or more future dates. For a retiree, it can turn an uncertain income into a known one.

Imagine you'll convert £2,000 a month from your private pension over the next twelve months — £24,000 in all. If you fix the rate at ฿44, you know you'll receive ฿88,000 every month, or ฿1,056,000 over the year, whatever the pound does. If it falls to ฿40, you're protected. If it rises to ฿47, you won't benefit — but you'll still have exactly the income you planned on.

Things to know before you fix:

• You commit to the amount — so fix only what you're confident you'll need to convert.
• A deposit is often required — commonly around 10% for personal forward contracts.
• You can fix part, not all — many retirees fix half or two-thirds of the year's income and convert the rest as they go.
• It's about certainty, not profit — the aim is a dependable budget, not beating the market.

Our guide to forward currency contracts explains how they work in more detail.

Converting tax-free cash and other lump sums

Larger one-off conversions — a tax-free pension lump sum, the proceeds of a UK house, money for a condo or the ฿800,000 visa deposit — need more care than a monthly pension. On £100,000, the difference between a bank's margin and a specialist's rate can easily run to thousands of pounds, and a sharp move in the pound between deciding and converting can cost more still.

• Get a specialist quote and compare the baht that would arrive, not the fee.
• Convert in stages over weeks or months to avoid putting everything through on one bad day.
• Use a limit order to convert automatically if the pound reaches a level you choose.
• Convert only what you need in baht — leave long-term money invested in other currencies.
• Keep the paperwork — your transfer records matter for Thai tax and for your visa.

Building your retirement budget in baht

The simplest defence against currency risk is a budget built in baht, not pounds. Start with what you actually spend in Thailand each month — rent or condo fees, food, transport, utilities, health insurance, medical costs, travel, help for family — and add a margin for one-off costs and rising prices.

Then work backwards. How many pounds do you need to produce that many baht at a cautious exchange rate — say ฿40 rather than today's ฿44? Does your pension income cover it, with room to spare above the ฿65,000 visa income level if you use that route? If not, how much will you draw from savings, and how long can your savings sustain it?

Planning at a cautious rate gives you headroom. If the pound stays strong, you'll have a surplus to top up your buffer or enjoy. If it weakens, you've already allowed for it. Our cost of living calculator can help you estimate your monthly spending.

What to do if the pound falls sharply

1. Don't panic-convert — a sharp fall is the worst moment to convert large sums.
2. Live off your baht buffer while the pound recovers.
3. Keep regular transfers going — averaging works in both directions.
4. Trim discretionary spending for a few months if you need to.
5. Draw from savings held in other currencies rather than pounds.
6. Check your visa margin well before your extension date.
7. Consider fixing part of next year's income if the pound recovers.
8. Talk it through before making big changes.

Your State Pension: Thai account or UK account?

The State Pension gives you a simple choice. Paid into a Thai account, it's converted by DWP at the rate on the conversion date, with a 0.39% charge — competitive and automatic, but you take whatever the rate is that day. Paid into a UK account, it stays in pounds, so you choose when and how to convert — useful if you want to time transfers, hold pounds for UK costs or show regular transfers for your visa.

Many retirees have the State Pension paid straight to Thailand for simplicity, and manage their private pension and savings more actively. Either way, it's worth choosing deliberately rather than by default. Our guide to receiving a UK pension in Thailand explains the payment options.

The currency of your savings and drawdown

Most retirees have two kinds of money: income that arrives regularly, and savings or a pension pot they draw from. The second is where you have the most freedom to manage currency.

• Money for the next one to two years: mostly in baht, as your buffer.
• Money for the next few years: in steadier investments, in the currencies you'll spend — mainly baht and pounds.
• Long-term money: in a worldwide portfolio, spread across many currencies, so your future income isn't tied only to the pound.
• Drawdown currency: many expat pensions and platforms let you hold several currencies, so you can draw from whichever is stronger.

Our guide to currency risk in international portfolios explains how to spread long-term savings.

Why it pays to keep some pounds too

Managing currency risk doesn't mean converting everything to baht. Most retirees in Thailand still have costs in pounds: flights home to see family, UK property costs, gifts to children and grandchildren, subscriptions, a UK mobile number, perhaps a holiday in Europe. If your income is already in pounds, paying those costs in pounds involves no conversion at all — no margin, no rate risk.

A sensible pattern is to keep a modest pound balance for UK costs, a baht buffer for life in Thailand, and long-term savings spread across currencies. A multicurrency account lets you hold pounds and baht side by side and move between them when the rate suits you, rather than when a bill forces you to.

It also leaves your options open. Many retirees eventually move back to the UK for family or health reasons; others split their year between countries. Keeping part of your wealth in pounds means a change of plan doesn't require converting everything back at whatever the rate happens to be.

Currency, inflation and the frozen State Pension

Currency is only one of three pressures on a retiree's spending power in Thailand. The second is inflation in Thailand: rents, food and healthcare costs rise over time. The third is the frozen State Pension, which never rises while you live here. Together, they mean that a pension income that feels comfortable at 65 can feel tight at 80.

The answer is to plan for all three at once. Keep growth investments for the later years of retirement, take withdrawals at a sustainable rate, and build your plan around a slightly weaker pound and steadily rising baht costs. A plan that works under cautious assumptions will feel generous if things turn out better.

Three worked examples

Derek: a buffer and a fixed rate

Derek, 69, in Hua Hin, lives on £2,200 a month from his State Pension and a workplace pension. When the pound dipped, he converted more at poor rates to keep up his spending. Lawrence helps him build a ฿600,000 buffer and fix the rate on his private pension for the next twelve months through Vita Capital. Now he knows exactly what he has to spend each month.

Pat and Joan: the visa margin

Pat, 71, and Joan, 68, in Chiang Mai, use the income route for their visa. Their combined pension, at ฿44, clears ฿65,000 a month with some room — but at ฿40 it would be tight. They move part of their savings into a ฿800,000 deposit so the visa no longer depends on the exchange rate.

Steve: spreading his savings

Steve, 63, in Phuket, has £180,000 of savings, all in pounds. Lawrence moves two years of spending into baht and invests the rest in a worldwide portfolio across several currencies, drawn from whichever is stronger each year.

The mistakes we see most often

1. Converting through a high-street bank every month.
2. No baht buffer, so a weak pound forces conversions.
3. Waiting for the "right" rate and running short.
4. Budgeting at today's rate with no headroom.
5. Visa income only just above ฿65,000.
6. All savings in pounds.
7. Forgetting the frozen State Pension in long-term plans.
8. Converting a tax-free lump sum in one go at a poor rate.

Your pension currency checklist

• Know how many baht you need each month — and at what rate your plan still works.
• Build a one-to-two-year baht buffer.
• Choose how your State Pension is paid.
• Convert private income regularly at a good rate.
• Consider fixing the rate for the year ahead.
• Keep visa income comfortably above ฿65,000 — or use the deposit route.
• Spread long-term savings across currencies.
• Review once a year, at your visa extension.

Keeping your transfers secure

• Confirm bank details by phone before setting up any regular payment.
• Never act on emailed changes to payment details without checking them yourself.
• Use two-factor sign-in on every bank and transfer account.
• Use a private, protected connection on hotel, café and condo Wi-Fi.
