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

Providers that use the mid-market TWD/KRW 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 KRW, 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 TWD/KRW — 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.
