Who sets the rate
The rate you are given is not set by one party. It is the product of the mid-rate, the payment processor or card scheme, the operator, and often your bank. This page assigns each layer its margin and shows why the reference rate is not the rate you transact at.
Row 01Four layers, and none of them is “the market”
It is tempting to treat “the exchange rate” as a market fact, but the rate a gambling account gives you is chosen by the chain of parties handling the money. The mid-rate is only the base they mark away from. A processor or card scheme supplies a conversion rate on its leg. The operator supplies the rate at which your account converts, defined in its terms. Your bank supplies the final rate when money lands in an account of another currency. Each layer can add a margin, and the one number you see is the sum. Knowing which layer a given rate came from is what lets you read a conversion after the fact.
Row 02The interbank mid-rate is a reference, not a rate you can buy
The mid-rate is the midpoint between the rate at which banks will buy a currency and the rate at which they will sell it. It is a genuine market figure, and it is the correct benchmark, but it is not a rate at which anyone transacts: banks transact at either side of it, and consumers transact further away still. So when a comparison is made between “the exchange rate” and the rate on your conversion, the mid is the fair benchmark and the gap is real, but the expectation that a consumer could receive the mid is not realistic. The mid is a ruler, not a price; the price is the effective rate, and the ruler tells you how far the price sits from it.
A ruler, not a price
Use the mid-rate to measure the cost of a conversion, not as a rate you should expect to receive. No consumer transacts at the mid.
Row 03The card scheme or payment processor supplies its own rate
When a payment crosses currencies as it settles, the card scheme or processor behind it converts at a rate it sets, and that rate carries its own margin. This margin is separate from the operator’s and from your bank’s, and it applies on the scheme’s leg of the transaction. For a card deposit in one currency into an account in another, the scheme’s conversion can be the first margin applied; for a withdrawal, it can be applied on the way out. Because it is the scheme’s own rate, it is not something the operator chooses or the account terms disclose in detail — the terms describe the operator’s rate, while the scheme’s rate comes from the card network’s rules.
How a conversion happens
The sequence the scheme and the operator each touch, and where their margins enter the rate.
Row 04The operator sets the rate your account converts at
The rate your account applies is the operator’s, and it is defined in its terms — sometimes as a rate drawn from a named source plus a stated markup, sometimes as “the rate determined by us” with a margin range. This is the layer you can actually read, because the operator is the party with whom you have the contract. It is also the layer that decides whether a deposit is converted on arrival or held as a pocket, and whether a conversion fee is charged explicitly on top. When a question about a rate cannot be answered from the statement, the operator’s terms are where the answer is defined, and a request to the operator is what turns “the rate I was given” into “the rate you set”.
Row 05Your bank applies the final rate when the money lands
On a payout, the operator’s conversion is not necessarily the last one. If the money lands in a bank account held in a different currency, the receiving bank converts it at its own rate and takes its own margin, and that rate can be worse than the operator’s. The same is true of a card: a foreign-transaction fee or a scheme rate can be applied on receipt. This is why the effective rate on a payout is often described by the bank rather than the operator, and why the currency your own account holds matters more than the currency the operator pays in. Holding the payout currency, or a multi-currency bank account, is the way to avoid the final margin — where it is available and the bank’s own fees do not outweigh it.
Row 06Whose number is it, and what to ask
To find out whose rate a given conversion used, work backwards from the record. The operator’s rate should be visible in the account history or the terms; the scheme’s or bank’s rate appears on the card or bank statement for its leg. Asking the operator which source its rate draws on, and whether an explicit conversion fee applies, is the question that identifies the layer it controls. The scheme’s and the bank’s margins are outside the operator’s control and belong to those parties’ own terms. Separating the layers is the difference between a rate that feels arbitrary and a rate whose origin you can name.
- Find the operator’s rate It should be evident from the account history or defined in the terms.
- Check for an explicit fee A settled conversion fee is separate from the margin inside the rate.
- Look at the bank statement The scheme or bank rate appears on its own leg, not on the operator’s.
- Ask the operator the source Which rate its terms draw on is the layer it controls and can explain.

The currency mechanics explained here — how and when a deposit or payout is converted, what a multi-currency wallet holds, who sets the exchange rate you are given and where the spread sits, and what the conversion costs in money — are general descriptions of how those mechanisms usually work, not a quote and not a statement of the rates, fees, wallet rules or law that apply to you: exchange rates, markup, fees and the terms that govern a wallet differ between operators, payment processors, banks, card schemes, corridors and countries and change over time.
