What a "mid-market rate" actually is, why your bank always quotes something worse, and how to avoid losing money to hidden conversion fees.
An exchange rate is simply the price of one currency in terms of another — how many Canadian dollars it takes to buy one US dollar, for example. But ask three different sources for "the" exchange rate on any given day and you'll often get three slightly different numbers. That's because there isn't one single official rate; there's a constantly shifting market rate, and then a series of markups that different providers add on top of it.
The mid-market rate — sometimes called the interbank rate — is the midpoint between the global buy and sell prices for a currency pair at a given moment. It's the rate banks themselves use when trading large sums with each other, and it's generally treated as the closest thing to a "true" exchange rate. It's also what most rate-comparison tools, including ours, show by default.
Banks, card networks, and currency-exchange counters rarely give you the mid-market rate directly. Instead, they add a margin on top — sometimes 1–3%, sometimes more at airport kiosks — plus, in some cases, a separate flat fee. This margin is one of the ways these businesses earn revenue on currency conversion, and it's why the amount you actually receive when exchanging money is usually a bit less favorable than the headline rate you saw online.
Unlike the price tag on a product, exchange rates aren't fixed. Currency markets trade nearly around the clock on weekdays, with prices shifting in response to interest rate decisions, inflation data, political events, and simple supply and demand from traders, businesses, and travelers worldwide. That's why a converter that fetches live rates will show a slightly different number from one hour to the next, while a tool using fixed reference rates can drift further from reality the longer it goes without updating.
Two providers can both advertise "live rates" while charging very different margins on top. Check the all-in cost, not just the headline number.
These typically carry some of the widest margins, since they're optimized for convenience rather than competitive pricing.
When a foreign merchant or ATM offers to charge you in your home currency, it usually uses a worse exchange rate than letting your card issuer do the conversion.
Our currency converter pulls live mid-market rates from a public provider each time you load the page, and falls back to fixed reference rates — clearly labeled — if that source is unavailable.
It's the midpoint between the global buy and sell prices for a currency pair at a given moment — essentially the "true" exchange rate before any bank or provider adds a margin.
Banks and card networks add a margin on top of the mid-market rate, sometimes plus a flat fee, which is how they earn revenue on currency exchange. The bigger the margin, the worse the deal for you.
Yes. Currency markets trade nearly continuously on weekdays, so mid-market rates fluctuate constantly based on global supply, demand, interest rates, and economic news.
