The FSCA’s New 3-Year Plan & The ZARONIA Shift

The South African financial sector is undergoing its most significant regulatory evolution in a generation. While the market has been highly focused on the countdown to the Conduct of Financial Institutions (COFI) Bill, the Financial Sector Conduct Authority (FSCA) recently released its Three-Year Regulation Plan, signalling a broader, highly structured overhaul of financial market conduct.

Amidst these shifts, one major structural reform carries a firm, non-negotiable deadline that is fast approaching: the permanent discontinuation of the Johannesburg Interbank Average Rate (JIBAR) on December 31, 2026.

As the South African Reserve Bank (SARB) and the Market Practitioners Group (MPG) drive the migration to ZARONIA (South African Rand Overnight Index Average), financial institutions are advised to look past compliance as a “checkbox exercise” and actively prepare their teams for a massive operational shift.

Understanding the ZARONIA Shift: What’s Changing?

For decades, JIBAR has served as the bedrock benchmark for pricing loans, floating-rate notes, and derivatives in South Africa. However, in line with global shifts away from IBORs (such as LIBOR), JIBAR’s forward-looking, estimate-based methodology is being replaced.

ZARONIA represents a fundamental departure from the status quo:

• Transaction-Based, Not Estimated: Unlike JIBAR, which relies on bank quotes, ZARONIA is a backward-looking overnight rate calculated daily based on actual, unsecured wholesale funding transactions.
• Compounded in Arrears: Due to the fact that ZARONIA is an overnight rate, pricing legacy mid-term and long-term financial instruments requires compounding the rate in arrears. This introduces brand-new accounting, valuation, and system calculation mechanics.

With the JSE having already launched its system enhancements to facilitate voluntary conversion of listed debt instruments to ZARONIA, the timeline is moving rapidly.

The Three Operational Risks of Waiting

Waiting until late 2026 to address the JIBAR transition introduces severe operational and financial risks:

1. The Legacy Contract Bottleneck

Any JIBAR-linked commercial contract, derivative, or bond maturing after December 31, 2026, must be actively remediated. Legal, compliance, and treasury teams must audit these contracts and renegotiate fallback language to avoid legal uncertainty once JIBAR becomes non-representative.

2. Pricing and Valuation Discrepancies

Transitioning from a term rate with an embedded bank credit risk premium (JIBAR) to a near risk-free overnight rate (ZARONIA) alters cash flow dynamics and contract valuations. Organisations must understand how Credit Adjustment Spreads (CAS) will be applied to maintain economic neutrality.

3. Operational and Core System Readiness

Legacy IT infrastructure, treasury management systems (TMS), risk valuation models, and accounting systems must be reconfigured to handle backward-looking compounded rates.

Bridging the Knowledge Gap

The FSCA’s Three-Year Regulation Plan highlights a growing regulatory demand for operational resilience and professional competency. The ZARONIA transition cannot be siloed within the treasury department; its implications affect risk managers, legal advisors, corporate lenders, and executive committees alike.
