What is Mid-Market Rate?
The mid-market rate is the midpoint between the buy (bid) and sell (ask) price of a currency in the global interbank market. It is the fairest reference rate available and what Google, Reuters, Bloomberg, and Wise all display as "the exchange rate."
Definition
When banks trade currencies with each other, they quote two prices: the "bid" price they will pay to buy a currency, and the "ask" price they will sell it for. The mid-market rate sits exactly between those two — it represents the true wholesale market value without any retail markup. For example, if the interbank EUR/USD bid is 1.0850 and ask is 1.0852, the mid-market rate is 1.0851. Consumer-facing services rarely give you this rate directly — banks, airport currency-exchange counters, and tourist-area money changers typically add a margin of 2–10% on top, which they keep as profit. The mid-market rate is what services like Wise, Revolut, and some fee-free debit cards aim to deliver — they make money through small explicit fees rather than hidden currency margins.
Worked example
If the mid-market USD/EUR rate is 0.9100, then $1,000 USD should convert to exactly €910 at the wholesale rate. A typical airport exchange might give you €860 (a 5.5% spread, kept as their margin) — that's €50 lost on a $1,000 conversion. A multi-currency travel card (Wise, Revolut) would deliver around €906–908 plus a small fixed fee, much closer to the true €910.
Why it matters
Knowing the mid-market rate before you convert is the single most useful skill for avoiding currency rip-offs. Always check the mid-market rate on a free tool (Google, our converter, Wise) before accepting any quoted rate from a bank, exchange counter, or transfer service — the gap between the two is exactly what you would otherwise lose to hidden margin.

Frequently asked questions
Where can I get the actual mid-market rate?
For checking the rate: Google, our currency converter, Wise.com, and XE.com all show the mid-market rate (or extremely close to it). For actually converting money at near-mid-market: Wise multi-currency cards, Revolut Premium, and Charles Schwab debit card (for US residents) all deliver rates within 0.3–0.8% of mid-market.
Why don't banks give the mid-market rate?
Banks make money on the "spread" — the gap between the wholesale interbank rate and the retail rate they charge you. A 2–4% spread on every customer conversion adds up to billions in profit annually. Fintech competitors (Wise, Revolut) disrupted this by charging small transparent fees instead, but most traditional banks still rely on hidden FX margins.
Does the mid-market rate change?
Constantly. Currency markets trade 24 hours per day from Sunday 21:00 UTC through Friday 21:00 UTC. The mid-market rate updates tick-by-tick as banks transact — typically thousands of times per minute for major pairs like EUR/USD. Our converter refreshes hourly from Frankfurter (European Central Bank reference data), which is sufficient for retail planning purposes.
Is the mid-market rate the same as the interbank rate?
Effectively yes, in retail usage. The interbank rate is the broader market where banks transact wholesale; the mid-market rate is the midpoint of the bid-ask spread within that market. The two terms are used interchangeably in consumer financial content.

Spread (Forex)
The spread is the difference between the buy (ask) price and the sell (bid) price of a currency. For retail customers, this gap is the primary way exchanges, banks, and brokers earn revenue — often disguised as a "commission-free" service.
Interbank Rate
The interbank rate is the wholesale exchange rate at which major banks transact currencies among themselves. It is the foundation for all other rates and typically the tightest pricing available — institutional only.
Dynamic Currency Conversion (DCC)
Dynamic Currency Conversion (DCC) is a service offered at point-of-sale terminals and ATMs that lets you pay in your home currency instead of the local currency. It almost always uses a worse exchange rate than your card's native conversion — costing you 3–8% extra.
