Why South African Credit Caps Move With the Repo Rate
Summary
South Africa does not cap credit at a fixed percentage. The ceiling on unsecured credit is written as a formula, the repo rate multiplied by 2.2 plus 20 per cent a year, so the legal maximum changes whenever the Reserve Bank adjusts rates. Understanding the formula lets you work out the current ceiling yourself and check an offer against it.
The legal maximum on a South African loan is not a number, it is a formula. That is unusual, and it has a practical consequence: the ceiling that applied last year may not be the ceiling that applies today.
The formula
For unsecured credit, the regulations express the maximum as:
(repo rate × 2.2) + 20 per cent a year
Work an example. At a repo rate of 7.5 per cent, the calculation is 7.5 multiplied by 2.2, which is 16.5, plus 20, giving a ceiling of 36.5 per cent a year. If the Reserve Bank cuts the repo rate by one percentage point, the ceiling falls by 2.2 points.
Short term credit is treated separately, with a ceiling of 5 per cent a month.
Why it is built this way
A fixed cap goes stale. Set it low and credit disappears when funding costs rise; set it high and it stops protecting anyone when rates fall. Linking the ceiling to the repo rate published by the South African Reserve Bank keeps the relationship between the cost of money and the maximum price of credit roughly constant.
Fees sit outside the interest cap
This is the part that catches people out. The interest ceiling does not cover every charge, so a loan at a lawful interest rate can still be expensive once fees are counted.
- Initiation fee: R165 plus 10 per cent of the amount above R1,000, capped at R1,050, and not more than 15 per cent of the principal.
- Monthly service fee: capped, with the prescribed figure revised over time. Check the current gazetted amount.
- Credit insurance, where it applies, is a further cost.
On a small, short loan, the initiation fee alone can represent a large share of the total cost, which is exactly why it is separately capped.
Checking an offer yourself
- Find the current repo rate and compute the ceiling with the formula above.
- Add every instalment you will pay, then subtract the cash you actually receive. That difference is the total cost of credit.
- Ask the provider to itemise how much of it is interest, how much is the initiation fee, how much is service fees, and how much is insurance.
- If the interest component implies a rate above the ceiling, ask for the calculation in writing.
One habit worth keeping
Pay the initiation fee separately rather than financing it where you have the choice. Financing a fee means paying interest on a charge for the life of the loan, which quietly raises its real cost.
In short
Compute the ceiling from the repo rate, then count the fees separately. The cap protects the interest, not the total.
