Whether you’re an expat receiving salary from abroad, a digital nomad transferring freelance income, or a retiree moving pension funds to Thailand, choosing the right international money transfer service can save you thousands of baht annually. The traditional bank wire transfer — once the only option — now competes with specialised fintech services that offer significantly better exchange rates, lower fees, and faster processing. Here is a detailed comparison of the best options for sending money to Thailand.
Wise (Formerly TransferWise)
Wise has become the default recommendation for international money transfers to Thailand, and for good reason. The platform uses the mid-market exchange rate — the real rate you see on Google or Reuters — and adds a transparent fee that typically starts at 0.57 per cent of the transfer amount. There are no hidden markups, no inflated exchange rates, and no surprise charges. The total cost of a transfer is displayed before you confirm, eliminating the uncertainty that characterises traditional bank transfers.
For a transfer of 1,000 GBP to Thailand, Wise typically delivers approximately 43,500 to 44,000 THB (depending on the day’s rate), with a fee of around 5.70 GBP. The equivalent bank transfer might deliver 42,000 to 42,500 THB after the bank’s exchange rate markup and wire fees — a difference of 1,000 to 1,500 THB that compounds significantly over regular monthly transfers.
Transfer speed is competitive: most Wise transfers to Thai bank accounts complete within one to three business days, with some routes offering same-day delivery. The Wise multi-currency account additionally provides a debit card that can be used for ATM withdrawals in Thailand at the mid-market rate, making it an excellent tool for managing day-to-day spending before or alongside a Thai bank account.
OFX
OFX (formerly OzForex) specialises in larger international transfers and offers a compelling proposition for expats making substantial or regular payments. The platform charges no upfront transfer fees, instead generating revenue through a margin on the exchange rate. While this margin means the rate is slightly less favourable than Wise’s mid-market rate, the absence of a flat fee makes OFX competitive for larger transfers where the percentage impact of its margin is proportionally smaller.
The minimum transfer amount is 500 USD (or equivalent), positioning OFX for more substantial transactions rather than small, frequent transfers. For monthly salary transfers of 3,000 USD or more, OFX’s fee structure often matches or beats Wise’s total cost. The platform also offers forward contracts (locking in an exchange rate for a future transfer) and regular payment schedules — features particularly valuable for expats with recurring obligations like mortgage payments in their home country.
Transfer speed is typically two to four business days to Thailand, slightly slower than Wise for standard transfers. Customer service includes dedicated dealing room staff who can assist with large or complex transfers — a personal touch that automated platforms cannot provide.
Western Union
Western Union remains relevant for transfers to Thailand primarily because of its physical presence: thousands of agent locations across the country, including in small towns and rural areas where digital banking penetration may be lower. For recipients without Thai bank accounts, Western Union’s cash pickup service provides a solution that digital-only platforms cannot.
However, the convenience comes at a significant cost. Western Union uses its own exchange rates, which include a markup above the mid-market rate, in addition to a transfer fee that varies by amount and payment method. For a 1,000 GBP transfer, the combination of fee and exchange rate markup typically results in 1,500 to 3,000 THB less reaching the recipient compared to Wise — a substantial penalty for the convenience of physical collection.
Transfer speed is Western Union’s genuine advantage for urgent needs: many transfers are available for pickup within minutes, and bank deposits to Thai accounts typically complete within 24 to 48 hours. For emergency transfers or situations where speed outweighs cost, Western Union delivers.
Bank Wire Transfers
Traditional bank-to-bank wire transfers (via SWIFT) remain necessary for certain transactions — notably, the foreign currency transfer required for condominium purchases (which must be documented via an FET Form from a Thai bank). For regular income transfers, however, banks are generally the most expensive option.
A typical international wire transfer involves three layers of cost: the sending bank’s outgoing wire fee (often 15 to 40 GBP or equivalent), the correspondent bank fee (10 to 30 GBP deducted in transit), and the receiving bank’s incoming wire fee (200 to 500 THB). On top of these fees, the sending bank’s exchange rate typically includes a 1 to 3 per cent markup above the mid-market rate. For a 2,000 GBP transfer, total costs can reach 100 GBP or more — dramatically more expensive than specialised services.
The one scenario where bank wires offer value is for very large transfers (above 50,000 GBP), where some banks provide preferential “dealing room” rates that narrow the exchange rate margin. For property purchases and other major transactions, negotiating directly with your bank’s foreign exchange desk can sometimes yield competitive rates.
Choosing the Right Service
For regular monthly transfers of moderate amounts (up to 5,000 GBP equivalent), Wise consistently offers the best combination of rate, fees, speed, and transparency. For larger, less frequent transfers (5,000 GBP and above), comparing Wise and OFX at the time of transfer ensures you capture the best rate on the day. For emergency transfers requiring immediate availability, Western Union’s speed justifies its higher cost. And for property-related transfers requiring FET Form documentation, bank wires remain the only compliant option.
Many experienced expats maintain accounts with multiple services, using each for its optimal use case. The few minutes spent comparing rates before each significant transfer can yield savings that accumulate to meaningful amounts over a year of Thai living.
