The short answer

That's the right approach for most South African holidaymakers. It keeps the amount you carry through airports low, avoids paying a bank's foreign-notes fees on most of your money, and still gives you a safety net.

Two situations call for more. If you're a family arriving late at night at a smaller airport, or heading straight to an island, carry enough baht for the first two days. And because Thai immigration can ask to see evidence of ฿20,000 per person, it's worth having either some cash or an easy way to show your funds — more on that below.

If your card charges a percentage on every withdrawal abroad, fix that first. At the big banks, a ฿20,000 withdrawal can cost over R560 in South African fees before the Thai ฿220. At Capitec or GoTyme, it's R70.

Thailand's proof-of-funds rule

Thai immigration rules have long allowed officers to ask foreign visitors to show they have enough money for their stay. The amounts date from a 2000 Interior Ministry announcement, and the Tourism Authority of Thailand reminded travellers about them in July 2026:

Children under 12 are exempt. Because official sources differ on the figure for visa-exempt visitors — which covers most South African holidaymakers — it's safest to be ready to show the higher amount: ฿20,000 per person, about R9,800, or ฿40,000 for a family, about R19,600.

In practice, most travellers are never asked. Officers have discretion, and checks are more likely if you look like you might overstay or work. But if you are asked and can't show funds, it can count against you. Funds can be in baht, an equivalent amount in another currency, or documents showing equivalent funds — so a recent bank statement or banking app balance may help. Official guidance doesn't say a card on its own will always be accepted.

Staying longer than 30 days? Since 15 September 2026 South Africans get 30 days visa-free, with a one-off extension of up to 30 days at an immigration office for ฿1,900. A tourist e-Visa applied for before you fly gives 60 days from arrival.

Cash rules: South Africa and Thailand

You're unlikely to come near these limits on a normal holiday, but they matter if you're moving to Thailand, buying property or carrying cash for family:

Since 1 July 2026, everyone entering or leaving South Africa also completes the online SARS traveller declaration, no more than 24 hours before departure. SARS says you won't be refused travel just for not doing it beforehand, but failing to declare goods or cash can lead to detention, forfeiture or penalties. Failing to declare in Thailand is a criminal offence.

If you're thinking about carrying a large sum to Thailand for a deposit, a car or a property, don't. A bank or specialist transfer is safer, cheaper and leaves a clear record — and for property, a record of funds coming from abroad can matter later.

Should you buy baht before you fly?

Thai baht isn't a currency every bureau keeps in stock, but some big banks will order it. Standard Bank, for example, sells baht notes for delivery or collection, usually by the next business day, for a fee of 3.2% (minimum R150) plus a R100 admin fee — on top of its exchange-rate margin. You'll need your passport and travel ticket. Here's what the fees alone come to:

The minimum fees make small orders particularly expensive: buying a few thousand baht of arrival money at home costs about an eighth of its value before the exchange rate. A single ฿20,000 withdrawal at the airport in Thailand on Capitec costs R70 plus the ฿220 machine fee — about R178 in all.

So the sensible approach is: withdraw at the airport in Thailand on a low-fee card. If you'd rather land with baht in your pocket, buy a modest amount and accept that you're paying for the convenience. Don't buy your whole holiday budget at home.

Backup cash: rand or dollars?

Thailand has a large number of currency exchange counters. Bangkok's big specialist counters buy rand at close to the real rate — on 22 October 2026, SuperRich Thailand and Grand SuperRich were paying ฿2.03 for rand notes against a mid-market rate of about ฿2.04. But outside Bangkok's specialists, on the islands and in smaller towns, rand is often refused or bought at a poorer rate. US dollars are exchanged everywhere — which is why they make the safer emergency reserve if you'll be travelling beyond Bangkok.

• Bring clean, undamaged notes. Torn, marked or very old notes may be refused or exchanged at a lower rate.
• US$100 and US$50 notes usually get better rates than smaller notes, and newer series are preferred.
• Take your passport — exchange counters are required to see it.
• Compare two or three counters; rates are displayed on boards and vary.
• Count your baht at the counter before you leave.
• Avoid street touts offering better-than-posted rates.

Buying dollars at home attracts the same foreign-notes fees as baht, so keep the amount sensible — US$100 to US$200 is enough to buy you time if both cards are blocked or lost. Keep a little rand too, for the trip home from the airport in South Africa.

The cheapest backup of all is a second card from a second bank on a second network — a Capitec Mastercard and a GoTyme Visa, say. If one is blocked, the other still works, and neither needs you to carry cash.

How much cash you'll use each day

How much cash you'll actually need depends far more on your style of travel than on your budget. In Thailand, the bigger and more formal the business, the more likely it takes cards. The smaller and more local, the more likely it's cash only.

If you pay your hotel, flights and tours by card, a couple on a typical holiday often gets by on a few thousand baht a day in cash, more if they eat at markets and take taxis a lot, less if they're mostly in Bangkok malls and using Grab. Islands, rural areas and the north lean more heavily on cash than central Bangkok.

A practical routine: set a temporary daily limit in your banking app, withdraw ฿20,000 when you arrive, see how quickly it goes, and top up in the same large amounts. That keeps your fees low and tells you your real daily cash needs within a few days.

Keeping cash safe

Thailand is generally safe for visitors, but cash is the one thing you can't get back if it's lost or stolen — and many travel insurance policies, including the free cover that comes with some credit cards, cap cash at a modest amount or exclude it. A few habits help:

Split your money between your wallet, your bag and the hotel safe, and carry only the day's cash, especially on nights out, at the beach and on boat trips. Keep your emergency dollars separate from everyday cash and cards, and use the room safe for passports, spare cards and the bulk of your cash. Don't flash large notes in markets or bars, and check your travel insurance for its cash limit and the proof it needs, such as a police report.

If cash is stolen, report it to the Tourist Police (dial 1155) and get a written report for your insurer. If cards go missing at the same time, stop or freeze them in your banking apps first.

The best ways to get baht

Four options, from the cheapest for most people to the most convenient before you fly.

Moving to Thailand? Don't carry it — plan it

If you're relocating or retiring to Thailand, the question isn't how much cash to bring — it's how to move your money properly. A retirement visa typically requires ฿800,000 in a Thai bank account or a monthly income of ฿65,000; a condo purchase needs funds transferred from abroad; and savings, retirement annuities and investments all need a plan.

Carrying large amounts of cash is risky, must be declared above R100,000 when leaving South Africa and US$20,000 when entering Thailand, and leaves you without a clear record of where the money came from. A planned transfer — within your R2 million single discretionary allowance, or with SARS tax compliance approval above it — is safer and, at the right rate, can save a great deal.

Moving with children? School fees are usually the biggest cost to plan for. Ask about school-fee planning, or compare schools in our international schools directory.

Your cash checklist for the flight

• Two low-fee cards from different banks, one Visa and one Mastercard.
• A temporary daily limit set in your banking app for your first days.
• A few thousand baht for arrival — or a plan to withdraw at the airport.

• Proof of funds — a recent statement or balance screenshot on your phone.
• Your SARS traveller declaration, completed within 24 hours of departure.
• Notifications on and card stop set up in each app.
• Insurance documents and the cash-cover limit noted.
