Spending money in Thailand — the complete guide to getting the best rate

Thailand is one of the world's most popular travel destinations and one of the most consequential for money decisions. The combination of a flat 220 THB ATM fee, pervasive DCC at every terminal, and a cash-first economy means travellers with a standard bank card pay significantly more than those with a zero-forex card. On a two-week trip spending £2,000, the difference can easily be £100–150.

The Thai Baht and exchange rates

The Thai Baht (THB) is freely traded and liquid — you'll find competitive exchange rates both at ATMs and at licensed money changers in major cities. The mid-market rate is your benchmark. When Starling or Wise processes your payment in Thailand, you get within 0.1–0.3% of that mid-market rate. A standard UK bank card adds 2.75% on top of a rate that's already 0.2–0.3% below mid-market — meaning you're effectively paying 3% extra on every transaction.

ATM fees in depth: 220 THB every time

Every major Thai bank ATM charges foreign cards 220 THB per withdrawal — approximately £5 at current rates. This is non-negotiable at most banks. The exception is AEON ATMs (found inside BigC and Lotus malls, yellow branding) which sometimes charge 150 THB. The fee is charged regardless of how much you withdraw, making large withdrawals significantly more economical. On a 10,000 THB withdrawal, 220 THB = 2.2%. On a 2,000 THB withdrawal, 220 THB = 11%. Always withdraw as much as you'll comfortably use in the next few days.

Cash vs card: when you need each

Cash is required for: street food from vendors (pad thai, som tum, mango sticky rice), tuk-tuks and songthaews, temple entry fees, local markets (Chatuchak, the floating markets), traditional massage shops, speedboat and ferry transfers, and most small guesthouses and bungalows. Card is accepted at: 7-Eleven and Family Mart, mid-range and upmarket restaurants, hotel check-out, large tour operators, shopping malls (CentralWorld, MBK), and international chain coffee shops. A reasonable daily cash float is 500–1,000 THB for a day of sightseeing, more if eating exclusively at street stalls.

Money changers: the Superrich strategy

Licensed money changers in Bangkok and tourist cities often offer rates within 0.5–1% of mid-market — sometimes better than ATMs when you account for the 220 THB flat fee on small withdrawals. The most reputable are Superrich (orange and green branches — different companies, both legitimate) in Bangkok. Superrich Orange is widely considered to give the best rates in Bangkok for popular currencies. Always count your notes before leaving the counter. Never use unlicensed changers who approach you on the street.

DCC: a constant presence

Dynamic Currency Conversion is offered aggressively in Thailand — at ATMs, at card terminals in tourist restaurants, at hotel front desks, and even at some 7-Eleven machines. The Thai financial regulator does not enforce restrictions on DCC presentation. This means you will encounter it constantly. The rule without exception: always choose Thai Baht (THB). When an ATM asks 'Do you accept the conversion?' — decline. When a terminal shows a GBP amount and asks 'Would you like to pay in Pounds?' — say no. The THB amount with your zero-forex card will always be better.

Destination by destination: Bangkok vs the islands vs Chiang Mai

Bangkok is the most card-friendly part of Thailand. Modern restaurants, Grab (ride-hailing), 7-Eleven, malls, and hotel chains are all card-accepting. You need less cash here than on the islands. The islands (Koh Samui, Koh Phangan, Koh Lanta, Koh Tao) are more cash-reliant — many beach bars, long-tail boat operators, and small guesthouses are cash-only. Withdraw generously before heading to a less-connected island. Chiang Mai is similar to Bangkok in its card acceptance — temple and market spending requires cash, restaurant and café spending is increasingly card-friendly.

How much to budget for money costs

With a zero-forex card and the large-withdrawal strategy, a typical Thailand trip should cost almost nothing in money fees beyond the unavoidable 220 THB per ATM visit. Budget roughly £5 per ATM visit and plan 3–4 visits over a two-week trip: total unavoidable ATM fees of £15–20. With a standard UK bank card (2.75% forex + ATM fees): on £2,000 of spending, you'd pay approximately £55 in hidden forex fees plus £20 in ATM fees = £75 extra. Zero-forex card saves you £55 of that.
