SARB Proposes Replacing Prime Lending Rate with Repo Rate

Brought to you by SA Legal Academy: The South African Reserve Bank (SARB) has invited public comment on a discussion document exploring the potential replacement of the prime lending rate (PLR) with the SARB policy rate, commonly referred to as the repurchase (repo) rate.

In terms of the SARB’s ongoing efforts to modernise South Africa’s interest rate benchmarks, the proposed reform seeks to align the domestic financial system with international best practice. The SARB has noted that the PLR has become increasingly detached from its original purpose as a base rate for pricing credit, leading to widespread misconceptions regarding its function. The transition is intended to make the repo rate the primary reference rate for PLR-linked financial contracts.

The proposed timeline for this transition is linked to the cessation of the Johannesburg Interbank Average Rate (Jibar). According to the SARB, the reform is expected to take place following the final publication of Jibar, which is scheduled for 31 December 2026. Stakeholders and interested parties have until 20 March 2026 to submit input on the discussion document.

Key objectives of the proposed benchmark reform

  • Addressing the detachment of the PLR from its original purpose as a credit pricing base rate;
  • Modernising interest rate benchmarks to ensure consistency with global regulatory standards;
  • Reducing misconceptions and improving transparency in the pricing of financial contracts; and
  • Facilitating a structured transition following the termination of Jibar in December 2026.

What this means for you, your business, or your clients

  • For yourself: No immediate individual compliance filing is required; however, you must familiarise yourself with the transition from PLR to repo-based calculations to ensure accurate legal drafting and financial advice.
  • For your business: Firms must begin assessing the operational impact on internal treasury functions, accounting systems, and financial models that currently rely on the PLR or Jibar as a benchmark.
  • For your clients: Clients with long-term credit agreements, derivatives, or commercial contracts linked to the PLR will require guidance on the inclusion of fallback language and the eventual transition to the repo rate to mitigate interest rate risk post-2026.
