Overview
The South African Reserve Bank has set out a proposal to phase out the countrys prime lending rate as the principal benchmark referenced in loans and other financial contracts and to substitute the central banks policy rate in its place. The proposal is contained in a discussion paper released by the bank that outlines the rationale for the change and the timing considerations for implementation.
Why the change?
The SARBs paper argues that the prime lending rates function has become "largely administrative and detached from its original purpose." It highlights that the prime rate has been fixed at 350 basis points above the policy rate since 2001, a practice that, the paper says, has contributed to misconceptions about how loan pricing works and to an inflated perception of the prime rate as the base rate for credit pricing.
The discussion paper states that, contrary to popular belief, lending rates are set by a range of factors including bank funding costs and risk appetite rather than the prime rate alone. For that reason, the SARB prefers that the prime lending rate cease to be used as a reference and that the policy rate should take its place as the primary benchmark in contracts.
Current rates and scope
At present the prime lending rate sits at 10.25% while the repo rate - the SARBs policy rate - is 6.75%. The paper flags the substantial scale of the task: more than 3.2 trillion rand of contracts are estimated to be linked to the prime rate. Given that breadth, the document recommends that any move away from the prime lending rate be undertaken carefully and not before 2027.
Intended effects
The SARB says replacing the prime lending rate with the policy rate as the reference point would strengthen the connection between monetary policy decisions and the rates consumers pay on loans. The paper also contends that the change would make it easier for consumers to understand how banks are pricing credit.
Timing and caution
Because of the large volume of contracts tied to the prime rate, the central bank stresses a cautious approach to any transition. The paper explicitly states that moving away from the prime lending rate should be done carefully and indicates that 2027 is the earliest feasible date for such a change.
