ZARONIA transition for retail loans faces legal hurdles
The Market Practitioners Group's Cash Market Workstream has published recommendations examining the implications of Johannesburg Interbank Average Rate (Jibar) cessation on South Africa's retail credit markets. The paper highlights material obstacles for lenders in transitioning Jibar-linked retail loans to the South African Overnight Index Average (ZARONIA) under the National Credit Act.
Backward-looking rates clash with consumer law
The core challenge in transitioning Jibar-linked retail loans to ZARONIA stems from the National Credit Act (NCA) 34 of 2005.
The NCA mandates that every pre-quotation agreement must disclose both the applicable interest rate and the total cost of credit as an annual percentage, either calculated exactly as prescribed or within a 0.1% deviation.
While Jibar, a forward-looking benchmark, allows for upfront calculation and disclosure of instalments, a backward-looking rate like ZARONIA is only ascertainable five business days before each instalment's due date.
This inherent uncertainty means the rate cannot be fixed at the time of pre-quotation without risking a deviation beyond the 0.1% tolerance.
Consequently, a backward-looking ZARONIA rate is practically incompatible with the NCA's requirement for known annual rates and instalment amounts at the quotation stage.
This issue affects both new and existing retail mortgage loans, particularly those maturing beyond the anticipated Jibar cessation date.
The South African Jibar-linked residential mortgage market comprises approximately 129,307 contracts with an aggregate principal balance of ZAR77.356 billion.
Lenders face basis risk and consent hurdles
Non-bank financial institutions (NBFIs) face additional complexity in the ZARONIA transition.
Their mortgage lending is funded through Jibar-linked debt, relying on basis matching.
Losing this could lead to increased hedging costs.
Banks might transition to a Prime-linked rate, aligning with their Repo-linked funding, but determining an economically equivalent fair rate poses complications.
These scenarios are complicated by consumer legislation like the NCA and CPA.
A change in the reference rate is a material contract alteration, requiring mutual consent from retail borrowers.
Obtaining individual consent from a large existing book is unfeasible, potentially leading to numerous consumer complaints.
The perceived lack of transparency around fallback rates could result in customer dissatisfaction and attrition.
Legislative clarity is paramount
The transition from Jibar to ZARONIA in South Africa's retail market is a critical, yet fraught, undertaking.
While essential for global alignment, the current legal framework presents substantial hurdles for lenders and consumers alike.
Without swift legislative intervention, including "safe harbor" provisions, the risk of market disruption and consumer dissatisfaction remains unacceptably high.
