The hidden costs of currency conversion: How to avoid losing value when sending funds abroad

When sending money overseas from South Africa, the true cost of your transaction isn’t always obvious at first glance. Most people focus on visible fees, but in many cases, a large part of the cost is actually built into the exchange rate itself. If you’re not comparing the rate you’re offered to the real market rate, it’s easy to lose value along the way. Let’s take a closer look at where this happens, and how to avoid unnecessary costs.

The exchange rate you see on Google isn’t the one you get

When you check the “market rate” online, what you’re looking at is the interbank rate - the benchmark rate at which banks trade with one another. It’s a useful reference point, but it’s not the rate you’ll receive when you convert your funds.

Banks and most other payment platforms build their margin directly into the exchange rate they offer, applying a spread between the true market rate and the rate presented to you. This spread is rarely disclosed as a separate line item, which makes it difficult to assess how competitive your rate actually is - or how much value is being absorbed before your transfer is processed.

The practical effect is straightforward: the higher the spread, the less foreign currency you receive for the same amount of Rands. And because the margin is embedded in the rate rather than charged as a visible fee, most people are unaware of it until they compare providers.

Small differences add up quickly

It might be easy to overlook fractions of a percent, but in currency conversion, these differences matter more than you might expect. On a R1 million transfer, a rate that is 2% worse than the market rate could mean R20,000 in lost value. On R5 million, that figure rises to R100,000.

For anyone making regular offshore transfers - whether for investment, emigration, or international property purchases - these differences compound meaningfully over time.

A common pattern is for clients to focus on avoiding visible transfer fees while unknowingly accepting a less competitive exchange rate, which typically has a far greater impact on the total cost of the transaction.

This is why the provider you choose matters: it determines how transparent the pricing is, how competitive the rate you receive will be, and ultimately how much value you retain after conversion.

‘Zero fees’ doesn’t mean zero cost

Some providers advertise low or zero transfer fees as their primary differentiator, but this can be entirely misleading. The total cost of a currency conversion isn’t determined by the fee alone, but by the combination of the fee and the exchange rate applied. A provider charging no fees can still cost significantly more than one that charges a modest fee but offers a rate meaningfully closer to the interbank rate.

To assess the true cost of any transfer, three factors need to be considered together: the exchange rate being offered relative to the market rate, any additional service or transfer fees, and the total amount received after conversion. Evaluating any one of these in isolation paints an incomplete picture.

Compliance can be a hidden expense too

For transfers above R2 million abroad per calendar year, an Approval for International Transfer (AIT) from SARS is required before your funds can be moved. This is a standard regulatory step, but it’s one that carries real costs if it’s not managed correctly.

Banks will typically require the necessary documentation before processing a transfer, but they rarely assist clients in preparing it. The result is that many people turn to accountants or tax advisors for support - incurring additional third-party fees that wouldn’t have been necessary with the right transfer provider.

More significantly, incomplete or incorrectly submitted AIT applications can delay a transfer by several weeks. In a volatile currency environment, a delay of that length can mean executing at a materially worse exchange rate, effectively adding an invisible cost to what was already a complex transaction.

Working with a transfer provider that offers compliance support as part of the service - managing AIT applications and documentation at no extra cost - eliminates both the third-party expense and the risk of delays.
