If you've ever sent money abroad through your regular bank and been surprised by how much less the recipient got than you expected, you've run into the most common hidden cost in international transfers: the exchange rate markup. Understanding how that works is the key to understanding why services like Wise built an entire business around it.
The core difference: how the exchange rate is set
Traditional banks typically don't charge a large, obvious transfer fee — which is exactly what makes their pricing hard to compare. Instead, they apply their own exchange rate, one that's marked up above the real "mid-market" rate (the actual midpoint between buy and sell prices on global currency markets). That markup is often 2–5%, quietly baked into the amount your recipient receives, with no separate line item calling it out.
Wise does the opposite: it charges a small, transparent fee upfront and uses the real mid-market exchange rate for the conversion itself. For a $1,000 transfer, that difference alone can mean $20–50 more reaching the recipient, depending on the currency pair and your bank.
Speed comparison
- Traditional bank wire transfers typically take 1–5 business days, and can take longer for less common currency corridors. They often route through intermediary banks, each of which can add both time and additional fees.
- Wise transfers are often same-day or next-day for major currency pairs, because Wise uses local bank networks in each country rather than routing everything through the international SWIFT system.

When a traditional bank might still make sense
Wise isn't automatically the better choice in every situation:
- If you're already sending money between accounts at the same bank internationally (some banks offer free or discounted internal transfers)
- If you need a physical branch for cash-based transactions
- If the recipient country isn't well-supported by Wise's local transfer network, in which case fees can be less competitive than advertised
What to actually check before you send
Regardless of which service you use, do this before confirming any international transfer:
- Look up the real mid-market exchange rate independently (a quick search for "USD to EUR mid-market rate" works)
- Compare that number to the rate you're being offered
- Add up the total cost: transfer fee plus the value lost to exchange rate markup — not just the fee alone
The fee is rarely the biggest cost. The exchange rate markup usually is, and it's the one most people never check.
