What's the cheapest way to send money from Singapore to Thailand?

Providers that use the mid-market SGD/THB rate with a transparent flat fee (e.g. Wise) almost always beat a bank, which hides its margin in a worse exchange rate. Always compare the amount that actually lands in THB, not the advertised "no fee".

What is the mid-market rate?

The mid-market (interbank) rate is the real midpoint between buy and sell prices for SGD/THB — the rate you see on Google. It carries no margin; the markup is what most banks add on top.

Why does the amount received differ between providers?

Two levers: the exchange rate margin (a hidden % on top of mid-market) and explicit fees. A 3–5% rate margin on a large transfer usually costs far more than a visible flat fee.

The real rate vs the hidden cost

Today's real rate
The mid-market rate is 1 SGD = 26.5517 THB.
Send 1,000 SGD
At the real rate, 1,000 SGD should arrive as about 26,552 THB in Thailand.
The hidden cost
A typical bank or legacy app bakes in a ~4% exchange-rate margin — on this transfer that's roughly 1,062 THB less than the mid-market rate, before any flat fee.
