In brief (TL;DR): South African banks build wide margins into international transfer exchange rates. A specialist forex provider like WBForex works on tighter margins — and on larger transfers, the difference in what arrives in your UK account can be significant.
When you transfer money from South Africa to the UK, the rate you are offered matters a great deal. The difference between what a bank charges and what a specialist provider charges stays in your pocket — or it does not.
How exchange rates work
The ZAR/GBP rate moves constantly, driven by global supply and demand. The "interbank rate" is what banks charge each other — the sharpest possible rate, but one that is never passed on to ordinary customers. Banks and specialist providers add their own margin on top. The question is how much.
South African commercial banks apply wider margins on international transfers because foreign exchange is not their core business. They process the transfer, but the rate reflects a significant markup over the interbank rate. Specialist providers like WBForex work on tighter margins because forex is all we do.
Why the margin matters more than you think
On small transfers, the difference between a wide bank margin and a tighter specialist margin may not feel dramatic. But on larger transfers — R500,000, R1 million, or more — the gap compounds meaningfully. Contact WBForex for a live comparison and we will show you exactly what the difference looks like for your specific transfer amount.
Simple ways to get a better rate
Get a quote before you use your bank. The comparison is usually eye-opening. Most clients who come to us do so after seeing what their bank was actually charging.
Transfer larger amounts less frequently. Every transfer carries a fixed SWIFT fee (typically R250). Fewer, larger transfers reduce the impact of that fixed cost.
Transfer during business hours. Currency markets are most liquid during London and Johannesburg trading hours. Rates tend to be tighter during these windows.
Ask about timing. If your transfer is not time-critical, we can advise on whether the current rate environment favours moving now or waiting. We will never predict where rates are going — but we can give you context on where they have been.
