The in duplum rule is a legal principle originating from Roman law and part of South African common law. The rule limits the amount of interest that can accumulate on a debt. It essentially states that the total amount of unpaid interest cannot exceed the original outstanding capital amount of the debt. In other words, once the unpaid interest equals the principal debt, the interest stops accruing. The rule aims to protect debtors from excessive interest accumulation and encourages lenders to pursue debt recovery promptly.
There have been significant differences of opinion in the case law.
In 2023, the KwaZulu-Natal High Court ruled in Municipal Workers Retirement Fund v Umzimkhulu Local Municipality that the in duplum rule does not apply to statutory interest on late pension fund contributions under section 13A of the Pension Funds Act (PFA). After this case, the Office of the Pension Funds Adjudicator (OPFA) issued Communication 1 of 2024 confirming that it supported the view of the court that the in duplum rule does not apply to interest arising from the non-payment of arrear contributions in terms of section 13A(7).
However, in March 2025, in Blue Crane Route Municipality v Municipal Workers Retirement Fund, the Eastern Cape High Court handed down a judgment that the in duplum rule does apply to arrear contributions. This prompted the OPFA to issue Communication 1 of 2025 on 8 May 2025, in which they reconsidered their position on the matter and confirmed that the in duplum rule does, in fact, apply to outstanding employer contributions to a retirement fund.

FSCA’s survey on two-pot fees
In September 2024, the FSCA surveyed 111 retirement fund administrators and six self-administered funds to assess two-pot retirement system fees.
Their key findings can be summarised as:
The FSCA aims to ensure fees align with costs incurred, promoting transparency and protecting retirement fund members.
Retirement fund trustees and management committees are encouraged to discuss their fees with their consultant, to appreciate the context of the FSCA’s survey at a point in time when information around two-pot implementation was not completely understood, and to make sure that their fees are reasonable.
