South Africa’s transition from JIBAR to ZARONIA represents a fundamental shift in how interest rates are referenced, valued and managed.
ZARONIA is an overnight, transaction-based rate replacing the forward-looking JIBAR benchmark. While JIBAR will continue to be calculated until 31 December 2026 for legacy exposures, firms must now adapt systems, models and workflows.
