Prime Interest Rate History South Africa
The South African prime lending rate is currently 10.25% per annum, effective 21 November 2025. This page tracks every rate change from 2000 to present, explains how the prime rate is set, and shows the real-world impact on bond repayments.
How the Prime Rate Works
The prime lending rate is the benchmark interest rate that South African commercial banks use to price home loans, vehicle finance, and personal loans. It is set at exactly 3.5 percentage points above the SARB repo rate. This spread has been fixed since 2012 and is maintained by all major banks.
The South African Reserve Bank (SARB) Monetary Policy Committee (MPC) meets six times per year to review the repo rate. When the MPC raises or cuts the repo rate, the prime rate moves by the same amount on the same day. Banks do not have discretion over this — the spread is fixed by convention and competitive pressure.
Most home loans in South Africa are priced at prime or prime minus a concession (e.g. prime – 0.5% for strong credit profiles). Some riskier loans are granted at prime + 1% or higher. A smaller prime rate concession on a large bond translates to significant savings over a 20-year term.

Impact on Bond Repayments
Every 0.25% rate change meaningfully affects your monthly bond repayment. The table below illustrates the effect of a 1% change in interest rate on a 20-year bond at different loan sizes.
| Bond Amount | At 9.25% | At 10.25% (current) | At 11.25% | Monthly change per 1% |
|---|---|---|---|---|
| R800,000 | R7,329/mo | R7,856/mo | R8,402/mo | ~R546/mo |
| R1,200,000 | R10,994/mo | R11,784/mo | R12,602/mo | ~R818/mo |
| R1,800,000 | R16,491/mo | R17,676/mo | R18,903/mo | ~R1,227/mo |
| R2,500,000 | R22,932/mo | R24,550/mo | R26,254/mo | ~R1,705/mo |

Link Between Repo Rate and Prime Rate
The SARB uses the repo rate as its main monetary policy tool. When inflation is rising, the SARB raises the repo rate to make borrowing more expensive, which slows spending and reduces inflationary pressure. When the economy needs stimulus, the SARB cuts the repo rate.
The repo rate is the rate at which the SARB lends money overnight to commercial banks. Banks then lend to consumers at a markup — the prime rate is that markup standardised across the industry. Because all major banks maintain the same prime-to-repo spread, there is effectively no competition on the base rate itself — competition happens through concessions granted to individual borrowers.
SARB MPC Meeting Schedule 2026
The Monetary Policy Committee meets six times per year. Rate decisions are announced at a press conference by the SARB Governor. The 2026 schedule is as follows:
| Meeting | Statement Date |
|---|---|
| MPC 1/2026 | 29 January 2026 |
| MPC 2/2026 | 26 March 2026 |
| MPC 3/2026 | 21 May 2026 |
| MPC 4/2026 | 23 July 2026 |
| MPC 5/2026 | 17 September 2026 |
| MPC 6/2026 | 19 November 2026 |
Prime Rate Phase-Out Proposal
In 2023, the SARB and National Treasury began exploring replacing the prime rate with the South African Overnight Index Average (ZARONIA) as the benchmark for floating-rate loans — a shift similar to reforms in the UK (LIBOR to SONIA) and US (LIBOR to SOFR). The proposal would align South Africa with international risk-free rate reform.
Under the proposed framework, home loans would still float with market rates but would reference ZARONIA plus a credit spread, rather than prime. As of March 2026, no firm implementation date has been set. Existing bonds would be grandfathered or converted via a published transition methodology. The SARB has indicated this is a medium-term project unlikely to affect bonds signed before 2028.
