The exchange rate margin: the fee nobody puts on the receipt
A conversion charged inside the rate looks like no charge at all. Understanding where it sits is the difference between knowing what currency costs your company and guessing at it.
A price expressed in a unit you cannot check
Currencies trade against each other continuously, and at any moment there is a reference rate at which they are actually changing hands between institutions. When a provider converts money for a company, it can charge for the service in one of two ways: a fee stated separately, or a rate slightly worse than the reference one.
The second method is the common one, and its advantage to the seller is not that it is cheaper to operate. It is that it is difficult to compare. A fee of 0.4 per cent is a number that can be put next to another number. A rate of 1.0782 against a reference of 1.0825 is the same information expressed in a form that requires a second source and a timestamp to decode.
This is why "no fees" is a claim that deserves a follow-up question rather than appreciation. A service with no fee and a margin inside the rate is not free; it is priced somewhere the buyer is not looking. The revenue exists either way.
Small percentages, repeated
Margins on retail and small-business currency conversion are typically fractions of a per cent up to several per cent, depending on the provider, the currency pair and the amount. On a single holiday transfer the difference is negligible. On a company converting its revenue every month, it compounds into a cost that nobody has budgeted because nobody has seen it.
Consider a company invoicing EUR 200,000 a year in dollars and converting each payment on arrival. A margin of one per cent is EUR 2,000, which is roughly the annual cost of a part-time bookkeeper. The company has not decided to spend that money; it has simply never been shown the line.
The awkward part is that the loss is invisible in the accounts as well. The conversion appears at the rate that was applied, so the books balance perfectly. Nothing is missing. The cost is inside the number, and internal reporting has no way to separate it.
Charge a fee, and show it
The alternative is not complicated. Apply the rate you display, add nothing to it after approval, and charge for the work as a fee written on its own line.
That is how currency exchange at Reibanq is priced: no margin added on top of the rate shown, a declared fee of 0.35 per cent, conversion across 38 currencies, and the rate and the fee both written on the record the accountant receives. The company can measure the cost, which means it can also argue about it. Reibanq accounts run on payment services supplied and managed by Orenda FS B.V., and client funds are held separately from Reibanq's own money.
- The rate on screen before you confirm is the rate applied to the conversion.
- The cost of the service is a fee, visible next to the amount it applies to.
- Rate and fee both appear on the receipt, so reconciliation does not require a second source.
- Conversion happens when you ask for it, not automatically when money arrives.
Measuring what you currently pay, in ten minutes
Any company can establish its own exposure without changing provider. Take the last five conversions from the statement. For each one, note the amount, the currency pair, the date, the time if it is recorded, and the rate applied.
Then find the reference rate for that pair at that moment. The European Central Bank publishes daily reference rates for the euro, and any market data source will give an intraday figure. The difference between the reference rate and the applied rate, expressed as a percentage, is what the conversion cost, in addition to any fee that was charged separately.
Multiply by annual volume. The resulting number is normally the most persuasive argument in the discussion that follows, because it is arithmetic rather than opinion.
Transparency is not a forecast
Seeing the cost of a conversion does not tell a company when to convert. Rates move for reasons that have nothing to do with any individual business, and a company that starts timing the market with its working capital has taken on a second job it did not want.
The more defensible approach is structural: convert what is genuinely surplus, price the cost of conversion into what you charge, and keep the timing decision small enough that being wrong about it does not matter. Transparency serves that approach by making the cost of each option visible. It does not replace the decision.
What the margin is, in practice
What is an exchange rate margin?
It is the difference between the reference rate at which currencies are trading and the rate a provider applies to your conversion. Because it is expressed inside the rate rather than as a charge, it does not appear as a fee on the receipt.
Is a service with no conversion fee cheaper?
Not necessarily, and often not. A provider with no stated fee is normally taking its revenue inside the rate. The only way to compare two offers is to convert both to the same unit: what did the conversion cost against the reference rate at that moment, fee included.
Which reference rate should I compare against?
For euro pairs, the European Central Bank publishes daily reference rates, and any market data source will give an intraday figure. What matters is using the same source consistently and recording the time of the conversion.
How is currency exchange priced at Reibanq?
The rate shown before you confirm is the rate applied, with no margin added on top of it, and the cost of the service is a declared fee of 0.35 per cent. Both the rate and the fee are written on the record.
