What's the cheapest way to send money from South Korea to Vietnam?

Providers that use the mid-market KRW/VND 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 VND, 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 KRW/VND — 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 KRW = 18.2432 VND.
Send 1,000 KRW
At the real rate, 1,000 KRW should arrive as about 18,243 VND in Vietnam.
The hidden cost
A typical bank or legacy app bakes in a ~4% exchange-rate margin — on this transfer that's roughly 730 VND less than the mid-market rate, before any flat fee.
