What is the mid-market rate?
The mid-market rate is the midpoint between the price at which dealers buy a currency and the price at which they sell it in the wholesale market at a given moment. It carries no markup, so it is the benchmark for judging the rate a bank or payment provider offers you. Example (round numbers, not a live rate): if dealers buy euros at 1.0990 US dollars and sell at 1.1010, the mid-market rate is 1.1000, and 100,000 euros is worth 110,000 dollars; a quote of 1.0890 pays 108,900 dollars, a cost of 1,100 dollars or 1%.
- The mid-market rate is the midpoint of the wholesale buy and sell prices for a currency pair, with no markup.
- The BIS Triennial Survey put global foreign exchange trading at $9.6 trillion per day in April 2025, with the US dollar on one side of 89% of trades.
- The European Central Bank publishes euro reference rates at around 16:00 CET for information only and strongly discourages using them for transactions.
- The Federal Reserve's H.10 rates are noon buying rates in New York, certified by the New York Fed for customs purposes.
- Comparing a provider's quote with the mid-market rate at the same moment shows the markup you pay inside the rate.
How the mid-market rate works
Banks and dealers quote two prices for every currency pair: a bid, the price at which they will buy, and an ask, the price at which they will sell. The mid-market rate sits exactly halfway between them. It moves continuously while the market is open, because the market is very large: the Bank for International Settlements (BIS) found that trading reached $9.6 trillion per day in April 2025, with the US dollar on one side of 89% of all trades.
Nobody trades at the mid-market rate itself. It is a reference point. Official bodies publish fixed snapshots that businesses also use for accounts and customs:
| Benchmark | Published by | When | Intended use |
|---|---|---|---|
| Euro foreign exchange reference rates | European Central Bank | Around 16:00 CET each working day, from a concertation between central banks at about 14:10 CET | Information only; the ECB strongly discourages using them for transactions |
| Foreign Exchange Rates (H.10) | Federal Reserve Board | Daily rates, released weekly | Noon buying rates in New York for cable transfers, certified by the New York Fed for customs purposes under section 522 of the Tariff Act of 1930 |
| Live mid-market rate | Market data from dealer quotes | Continuously while markets are open | Measuring the markup in a quote at the moment you convert |

Where a business meets the mid-market rate
Every conversion is priced against it: paying a supplier in another currency, converting a buyer's payment on arrival, or moving money between currency balances. Providers describe their pricing against it in different words, so read the phrase and the number together.
| Provider | How its own pricing page describes conversion |
|---|---|
| Wise Business (US) | States it does not inflate the mid-market rate; conversion fee varies by currency, from 0.23% |
| Airwallex (US) | 0.5% above interbank rates for major currencies, 1% for all other currencies |
| WorldFirst (UK) | Standard rate up to 0.50% for major currencies; 0.30% for a new customer's first six months |

Pricing pages use both terms. What matters is the number added on top, which our guide to FX margins explains.
Common mistakes
- Comparing against a stale rate. Check the mid-market rate at the moment of the quote, not a figure from the morning.
- Pricing deals off a reference rate. ECB and H.10 rates are fixed snapshots; the ECB itself discourages using its rates for transactions.
- Reading "no fee" as "mid-market". A transfer with no stated fee can still carry a markup inside the rate.
- Ignoring the size effect. A 1% gap on 100,000 euros is 1,100 dollars at the example rate above; on a year of supplier payments it adds up quickly.

The spot rate is the price for immediate conversion, and a forward contract fixes a rate for a later date. Our currency converter shows indicative rates for common pairs.
Helm agrees pricing with each business in writing before the account opens, and shows the rate, the fee and the expected arrival before you confirm each payment.

What is the mid-market rate in simple terms?
It is the halfway point between the price at which dealers buy a currency and the price at which they sell it. It has no profit added, so it is the fairest benchmark for comparing quotes.
Can a business convert at the mid-market rate?
Rarely exactly. Providers add a margin or charge a separate fee, so the useful question is how far a quote sits from the mid-market rate at the same moment, and what any fixed fee adds.
Is the ECB reference rate the mid-market rate?
It is a daily snapshot set at around 16:00 CET through a concertation between central banks. The ECB publishes it for information only and strongly discourages using it for transactions.
What rate does US Customs use?
The Federal Reserve's H.10 release states that its rates are noon buying rates in New York, certified by the Federal Reserve Bank of New York for customs purposes under section 522 of the Tariff Act of 1930. The release gives daily rates for major currencies against the dollar.
How do I calculate the markup in a quote?
Subtract the quoted rate from the mid-market rate, divide by the mid-market rate and multiply by 100. A quote of 1.0890 against a mid-market rate of 1.1000 is a 1% markup.
