The short answer

The right level of investment risk is the one that gives you enough growth to reach your goals, that you could afford to see fall without changing your plans, and that you could live with through a bad year without selling. Work out what you need, what you can afford to lose temporarily and how you'd feel in a downturn, then choose a mix of shares, bonds and cash that fits all three. Keep a cash buffer so you never have to sell at a bad time, spread your money widely, match currencies to where you'll spend it, and reduce risk gradually as each goal gets closer. Lawrence offers a free review to find your level — and to check that your existing investments really match it.

What investment risk really means

In everyday language, "risk" means the chance of something bad happening. In investing, it mostly means uncertainty: the value of your investments will move up and down, sometimes sharply, and nobody knows in advance by how much or when. Shares can fall by a third in a few weeks. Bonds can have a poor year. Even cash carries a risk — that inflation quietly eats away at what it will buy.

That uncertainty is exactly why investing pays. Investors who accept the ups and downs of shares have historically been rewarded with higher long-term growth than those who stay in cash. The Barclays Equity Gilt Study, which tracks UK markets back more than a century, found that shares beat cash in about 91% of all ten-year periods. Risk and return are two sides of the same coin: you can't have one without the other.

So the aim is never to avoid risk altogether. It's to take the right risks, in the right amount, for money you won't need for a while — and to protect the money you will need soon. Understood that way, risk becomes something you manage and use, not something to fear.

The three angles: attitude, capacity and need

1. Attitude to risk — how you feel

Your attitude to risk is emotional. Some people check their portfolio once a year and shrug at a 20% fall; others lose sleep over a 5% dip. Neither is right or wrong, but it matters enormously, because an investor who panics and sells in a downturn turns a temporary fall into a permanent loss. A portfolio is only as good as your ability to stick with it.

A useful test is to imagine opening a statement showing that your investments have fallen by a quarter. Would you hold on calmly, add more while prices are low, or feel an urgent need to sell? Your honest answer says a lot.

2. Capacity for loss — what you can afford

Capacity for loss is financial, not emotional. It asks: if your investments fell sharply and took several years to recover, would your life change? Could you still pay the rent, the school fees, the medical bills? Would you have to delay retirement or sell at the bottom to raise cash?

Two people with the same attitude can have very different capacity. A 45-year-old with a good salary, an emergency fund and twenty years until retirement can ride out a big fall. A 70-year-old living on withdrawals from the same portfolio may not be able to. Capacity for loss usually depends on your other income, your cash reserves, your timescale, how essential the money is and how much flexibility you have in your spending.

3. Required return — what you need

The third angle is often forgotten. What growth do you actually need to reach your goals? If you already have more than enough, there may be no reason to take much risk at all. If you're starting late, or your goals are ambitious, a portfolio that's too cautious may never get you there — which is a risk of its own.

The right level of risk sits where the three meet. When they disagree — say you're comfortable with risk but can't afford losses, or you need growth but hate volatility — that's precisely when a conversation with an experienced adviser helps most.

Attitude, capacity and need at a glance

The three angles measure different things. A good plan checks all of them — and takes the lowest of the three as the limit.

If your attitude says "adventurous" but your capacity says "cautious", capacity wins.

Typical risk profiles

Most advisers and investment platforms group investors into a handful of profiles, each matched to a broad mix of investments. The labels vary, but the idea is the same everywhere: the more shares in the mix, the higher the expected long-term growth — and the bigger the ups and downs along the way.

A cautious investor might hold around a third of their money in shares, with the rest in bonds and cash. A balanced investor might hold around 60% in shares. An adventurous investor might hold 80% or more. The chart at the top of this page shows what that means in practice: the same 40% fall in shares costs a cautious £200,000 portfolio about £24,000, a balanced one about £48,000 and an adventurous one about £72,000 — temporarily, if the investor holds on.

No profile is better than another. The best one for you is simply the one that matches your attitude, capacity and need — and that you'll stick with when markets are difficult. Many people also hold different profiles for different goals: an adventurous mix for money they won't touch for twenty years, and a cautious one for money they'll spend in three.

The main types of risk expats face

Market ups and downs are the risk everyone thinks of, but they're only one of several. Expats face a few that people at home rarely consider.

Market risk

The value of shares and bonds moves with economies, interest rates and sentiment. It can't be avoided if you want growth, but it can be diversified — spread across thousands of companies and many countries — and matched to your timescale, so money you need soon isn't exposed to it.

Inflation risk

The quiet risk. UK inflation hit 11.1% in October 2022, and even at a modest 3% a year, prices roughly double in 24 years. Money left in cash for decades feels safe, but its buying power steadily shrinks. For retirees in Thailand whose UK State Pension is frozen and never rises, inflation risk is especially real — which is why most long-term money needs some growth.

Currency risk

If you spend baht but your savings and pension are in pounds, every movement in the exchange rate changes what your money buys. A strong baht can cut a retiree's spending power by a tenth or more in a year or two. You can't remove currency risk entirely, but you can manage it — by holding near-term spending money in baht, spreading long-term money across currencies and fixing your rate on larger transfers. Our guide to currency risk in international portfolios covers this in depth.

Sequence risk

For anyone drawing an income, the order of returns matters. A big fall in the first years of retirement, while you're also taking withdrawals, does far more lasting damage than the same fall later on. It's one of the most important risks in retirement planning, and we cover it below.

Concentration risk

Too much in one company, one country, one property or one fund. It's common among expats who hold shares in a former employer, a single condo or a portfolio built around the UK. Our guide to diversification explains how to spread it.

Liquidity risk

Some investments can't be sold quickly, or only with penalties — property, some savings plans in their early years, certain alternative funds. That's fine for long-term money, but not for money you might need in a hurry.

Longevity risk

The risk of living longer than your money lasts. According to the ONS, a 65-year-old man in the UK can expect to live another 18.7 years on average and a woman 21.2 — and many will live well beyond that. Planning for 30 years of retirement is sensible.

Scam risk

Expats are a favourite target for "too good to be true" investments, cold calls and social-media offers. It's a risk you can avoid completely with a few simple checks, covered in our guide to investment scams and due diligence.

How deep — and how long — falls have been

Knowing what has happened before is one of the best ways to judge your capacity for loss. Markets fall regularly; what matters is how far, and how long they take to recover.

In the global financial crisis, world shares fell by around half from their peak, and the MSCI World index took almost six years to regain its pre-crisis high, in February 2013. In early 2020, world shares fell 34% in a matter of weeks as the pandemic struck — then recovered to their pre-pandemic level in about ten months. After the inflation shock of 2022, the index took about 26 months to regain its December 2021 high.

Bonds usually cushion share falls, but not always. In 2022, shares and bonds fell together — something Dimensional describes as relatively rare — and a classic US portfolio of 60% shares and 40% bonds ended the year down 11%, having been down 19% at its lowest point. In 2007–09, the same mix fell about 30% from peak to trough.

Two lessons stand out. First, falls of a third or more in shares happen every decade or so, and any long-term investor should expect to live through several. Second, recoveries have come — sometimes quickly, sometimes slowly — which is why time and a cash buffer are the investor's best protection. Past patterns are no guarantee of the future, but they're the best guide we have to what a "bad year" can look like.

Where to start

Someone to help you find the right level of risk, and the right way to manage currency risk when you move money.

Your cash buffer: the best protection there is

The single most effective way to increase your capacity for loss is surprisingly simple: keep enough cash that you never have to sell investments at a bad time. Market falls only become real losses when you sell. If your day-to-day needs are covered from cash, you can leave your investments alone to recover.

How much depends on your situation:

• Working expats: three to six months of spending, plus anything you'll need for known costs in the next year or two.
• Retirees drawing an income: one to two years of withdrawals, so a downturn never forces you to sell.
• Known big costs — school fees, a condo deposit, a car — in cash or very safe investments once they're within about three years.
• Medical costs: a reserve for the excess on your health insurance, and good cover so a big bill never forces a sale.

For expats, the buffer should mostly be in the currency you spend — baht in Thailand — so a swing in the pound doesn't shrink it just when you need it. Cash in a Thai bank account is protected by the Deposit Protection Agency up to ฿1 million per person per bank, so larger reserves can be spread across more than one bank.

Protection: the part of capacity people forget

Capacity for loss isn't only about markets. A serious illness, an accident or a death in the family can do more damage to a financial plan than any market crash — and in Thailand, without the NHS behind you, a single hospital stay can cost hundreds of thousands of baht.

Good protection is what lets your investments do their job. With comprehensive health insurance, you won't have to sell investments to pay a hospital bill. With life cover in place, a partner or children won't have to cash in savings at a bad moment. With critical illness or income protection, a long recovery doesn't mean raiding your retirement money. Each one raises your capacity for loss — and allows the rest of your money to be invested for growth with confidence.

Risk in retirement and the sequence problem

Risk changes character once you stop working. Before retirement, a market fall is an opportunity — your monthly savings buy more while prices are low. After retirement, when you're drawing money out, a fall at the wrong time can do lasting damage.

Imagine two retirees with identical portfolios and identical average returns over twenty years. The first has a bad two years at the start; the second has them at the end. The first must sell more units to pay their income while prices are low, leaving less to benefit from the recovery — and may run out of money years earlier. That's sequence risk, and it's why the years just before and after retirement need particular care.

How to manage it

• Keep one to two years of income in cash, so you never sell in a downturn.
• Hold a few more years in steadier investments such as bonds, to refill the cash.
• Leave the rest invested for growth — you may need it for thirty years.
• Be flexible: trimming withdrawals a little after a bad year makes a big difference.
• Take withdrawals from what has done well, which also rebalances the portfolio.

This "bucket" approach gives retirees the best of both: security for the next few years and growth for the decades beyond. It's exactly the kind of plan Lawrence builds with expats retiring in Thailand.

Reducing risk as goals get closer

Your capacity for loss isn't fixed — it falls as the date you need the money approaches. Money for a goal twenty years away can ride out several downturns. Money for a goal two years away can't afford a fall at all. That's why each goal deserves its own level of risk, and why that level should come down gradually as the date approaches.

School and university fees are the classic example. Money for a child who is three can be invested mostly in shares, giving it the best chance to grow. By the time the fees are a few years away, more of it should be in steadier investments, and the first year's fees in cash, in the right currency. Starting early is what makes this work: with 13 years to invest, growth can pay a large share of the bill.

Risk when you invest a lump sum

A house sale, an inheritance, a pension lump sum or a business sale brings a particular kind of risk decision. Investing it all at once has historically produced better results more often — Vanguard found a lump sum beat phasing in about two-thirds of cases — but a fall straight after investing can feel painful. Phasing it in over a few months reduces that regret, at the cost of some expected return.

The right answer depends on your capacity for loss and your attitude. If a 20% fall in the first year would make you sell, phasing in is worth it. If you'd hold on calmly, investing sooner usually wins. Many people choose a mixture — some now, the rest over six to twelve months. Our guide to lump sums and regular saving compares the two in detail.

Risk questionnaires: useful, but only a start

Most platforms and advisers use a short questionnaire to suggest a risk profile. They're a helpful starting point, but they have limits. They measure your attitude well, but often say little about your capacity or your need. They're often answered on a calm day, when everyone feels braver than they would in a crash. And they rarely account for the things that make expats different: two tax systems, two currencies, a frozen pension and medical costs without the NHS.

The best approach treats the questionnaire as the first step of a conversation. What did you actually do in 2020 or 2022? What other income will you have? What are your goals, and when? Which costs are in baht and which in pounds? Answering those questions together turns a generic score into a level of risk that genuinely fits your life.

The biggest risk of all: our own reactions

Study after study finds that investors earn less than the funds they invest in, simply because they buy after rises and sell after falls. The urge is natural — but it's expensive. J.P. Morgan found that $10,000 invested in the US market from 2005 to 2024 grew to about $71,750 if left alone, but only about $32,871 for an investor who missed just the ten best days. Seven of those best days came within two weeks of the worst, exactly when frightened investors had sold.

That's why matching your risk to your temperament matters so much. A slightly more cautious portfolio that you hold through thick and thin will usually beat a more adventurous one that you abandon in a panic. A clear plan, a cash buffer and someone to talk to when markets are frightening are the best protection there is.

Three worked examples

Mark: confident, but low capacity

Mark, 63, has £250,000 and plans to retire to Hua Hin next year. He describes himself as adventurous and holds almost everything in shares. But he'll rely on the portfolio for most of his income, with only a small UK pension and a frozen State Pension still years away. A free review with Lawrence shows his capacity for loss is far lower than his attitude: a 2008-style fall just after he retires could permanently cut his income. Lawrence builds two years of income in cash, mostly in baht, a few years more in bonds, and leaves the rest in a worldwide share portfolio. Mark keeps his growth — without the danger of selling at the bottom.

Sarah: too cautious for her goals

Sarah, 41, works in Bangkok and keeps £90,000 in cash because she "doesn't like risk". Her goal is to retire at 60 with a comfortable income. Her capacity for loss is high — a good salary, an emergency fund and nearly twenty years to go — but her money is barely keeping up with inflation. Lawrence shows her that cash is the bigger risk to her retirement, and they agree a balanced portfolio built in steps over twelve months, plus a regular savings plan. Sarah sleeps well because she understands the plan.

Tom and Ploy: different risk for different goals

Tom and Ploy, in their late thirties in Chiang Mai, are saving for their son's international education and for retirement. Lawrence sets up the education pot with a glide path — mostly shares now, moving to safer investments as fees approach — and the retirement pot more adventurously, as it won't be touched for twenty-five years. A baht buffer covers six months of spending, and life cover protects the family if either of them dies.

The mistakes we see most often

1. Judging risk on feelings alone and ignoring capacity for loss.
2. Too much cash for too long, losing ground to inflation.
3. No cash buffer, so a downturn forces a sale.
4. The same risk for every goal, whatever its date.
5. Ignoring currency when you spend baht and save in pounds.
6. Concentration in one company, country or property.
7. Not reducing risk before retirement or a big expense.
8. Selling in a panic after a fall.

Find your level of risk: a checklist

• List your goals, with an amount and a date for each.
• Work out what growth you need to reach them.
• Ask how you'd feel if your investments fell by a quarter — and what you did in 2020 or 2022.
• Check your capacity: other income, cash buffer, flexibility, timescale.
• Put protection in place: health, life and income cover.
• Choose a mix for each goal that satisfies all three angles.
• Match currencies to where you'll spend the money.
• Review once a year and at every life change.

Keeping your accounts secure

One risk is entirely within your control: the security of your accounts. Expats often manage money over hotel, café and condo Wi-Fi, which makes good habits essential.

• Use a password manager and a different strong password for every account.
• Turn on two-factor sign-in on every investment and bank account.
• Use a private, protected connection on public Wi-Fi.
• Never act on an unexpected call or message about your investments without checking it yourself.
