ZARONIA references 90 percent of cross-currency swap pricing
The South African Foreign Exchange Committee reported orderly domestic market conditions despite Middle East tensions and noted that 90 percent of cross-currency swap pricing now references ZARONIA, according to proceedings from its 18 June 2026 meeting.
ZARONIA adoption leads market resilience
The South African foreign exchange market maintained orderly trading conditions despite heightened geopolitical risks linked to Middle East tensions.
Domestic liquidity remained resilient across rand spot, forwards, and options markets, with bid-ask spreads normalizing after brief widening in March.
Real-money accounts were net buyers of rand in February, while hedge funds turned net sellers during March's volatility spike before their activity moderated.
Meanwhile, the benchmark transition from Jibar advanced substantially, with approximately 90 percent of cross-currency swap pricing now referencing ZARONIA.
At the global level, the Global Foreign Exchange Committee appointed Bernard Wee as Chair.
Algorithms challenge market governance
Committee members analyzed how artificial intelligence reshapes trading execution and compliance under the FX Global Code.
While algorithmic tools enhance order routing and dynamic pricing, members flagged risks of flash crashes, synchronized market behavior, and data protection breaches under POPIA.
The committee noted that quantitative models are easier to govern than subjective sentiment analysis tools.
Proposed reforms will expand SAFXC representation to buy-side participants and lengthen the Deputy Chair term to three years.
Paper rules vs trading reality
The ZARONIA milestone demonstrates effective execution in South Africa's benchmark overhaul.
However, addressing algorithmic trading risks through voluntary codes highlights a growing gap between fast-moving technology and slow-moving oversight.
Post-trade monitoring cannot replace rigorous upfront controls on automated systems.
