The mid market rate, also called the interbank or market rate, is the midpoint between the buying and selling prices of two currencies. It is the rate banks use among themselves and is widely used as a benchmark. Most providers add a markup to the mid market rate when serving businesses and individuals, so the rate a customer receives is usually slightly different.

How the mid market rate works

The mid market rate is calculated as the midpoint between the bid price, at which the market will buy a currency, and the ask price, at which it will sell. In other words it is the bid rate plus the ask rate divided by two. It reflects the fair value of one currency against another at a moment in time, with no profit margin, fee, or markup included. Because exchange rates move continuously, the mid market rate also changes throughout the day. It is the rate widely quoted by currency converters and financial data services as the headline market rate, current as of 29 April 2026.

Mid market rate and the markup

Banks and money transfer providers generally do not give businesses or individuals the exact mid market rate. Instead they apply a markup, also called a foreign exchange margin, which is the difference between the mid market rate and the rate offered to the customer. This markup is one of the ways a provider earns money on a currency conversion, and it may come on top of, or instead of, a separate transfer fee. Comparing a provider's offered rate against the mid market rate shows how large that markup is.

Why it matters to a business

For a business making cross border payments or holding foreign currency, the mid market rate is a useful benchmark for judging the cost of converting money. A rate close to the mid market rate means a small markup, while a rate far from it means a larger one, which adds up on high volumes or large amounts. Because each provider sets its own markup and it can vary by currency pair and amount, a business should compare the offered rate with the current mid market rate before converting, and confirm whether any separate fee also applies.

Frequently asked questions

What is the mid market rate?

How is the mid market rate calculated?
It is the average of the bid rate and the ask rate, that is the bid rate plus the ask rate divided by two. Because exchange rates move constantly, the mid market rate changes throughout the trading day.
Can a business get the mid market rate?
Most banks and providers add a markup, so customers usually receive a rate slightly different from the mid market rate. Some providers advertise rates close to the mid market rate but may charge a separate fee instead. Compare the offered rate and any fee before converting.
Why does the mid market rate matter?
It is a neutral benchmark for judging how much a provider charges to convert currency. Comparing the offered rate with the mid market rate shows the size of the markup, which can be significant on large amounts or high volumes.
