South Africa’s Monetary Policy Committee (MPC) announced a 25 basis point cut in the repo rate to 4.50% on October 29, 2025, matching market expectations. This marks a continuation of the easing cycle that began in September 2025, down from 5.50% in September 2024. The move reflects a response to moderating inflation and a desire to stimulate economic growth amid a complex global environment.
Drivers this month
- Inflation eased to 4.80% YoY in September 2025, below the 5.10% average for the past year.
- GDP growth forecast revised upward to 2.10% for 2025, supported by stronger mining and manufacturing output.
- Unemployment remains elevated at 32.50%, pressuring policymakers to maintain accommodative conditions.
Policy pulse
The current 4.50% rate sits comfortably below the 5.00% neutral rate estimated by the central bank, signaling a pro-growth stance. Inflation remains within the target band of 3-6%, allowing room for further easing if conditions improve.
Market lens
Immediate reaction: The South African rand (ZAR) appreciated 0.30% against the US dollar within the first hour post-announcement, reflecting relief at the predictable rate cut and improved risk sentiment.
Core macroeconomic indicators underpin the MPC’s decision. Inflation has steadily declined from a peak of 6.10% in early 2024 to 4.80% in September 2025. Meanwhile, GDP growth has shown resilience, with Q3 2025 expanding 2.30% YoY, up from 1.70% in Q3 2024. The fiscal deficit narrowed to 4.20% of GDP in FY2024/25, improving debt sustainability.
Inflation trends
Consumer Price Index (CPI) inflation has moderated due to lower food and energy prices. Food inflation dropped from 7.50% YoY in mid-2024 to 4.20% in September 2025. Energy costs eased following global oil price stabilization.
Fiscal policy & budget
Government spending remains disciplined, with a primary surplus projected for FY2025/26. Tax revenues have improved by 6.50% YoY, supporting debt reduction efforts. However, social spending pressures persist amid high unemployment.
External environment
South Africa faces external headwinds from slowing Chinese demand and geopolitical tensions in the Middle East. Commodity prices, especially for platinum and gold, have been volatile but remain supportive of export earnings.
Financial market indicators also illustrate the impact of the rate decision. The 2-year government bond yield fell from 7.10% to 6.80% post-announcement, while inflation breakeven rates declined from 5.30% to 5.00%. The rand’s volatility index decreased by 12% in the week following the decision.
This chart underscores a sustained easing cycle, with monetary policy loosening in response to falling inflation and steady growth. The bond market’s positive reaction signals confidence in the central bank’s calibrated approach.
Market lens
Immediate reaction: The South African 2-year yield dropped 30 basis points, reflecting expectations of a prolonged easing cycle. The rand strengthened modestly, indicating improved investor sentiment.
Looking ahead, the MPC’s path depends on inflation dynamics, fiscal discipline, and external risks. Three scenarios emerge:
Bullish scenario (30% probability)
- Inflation falls below 4.50% by mid-2026.
- GDP growth accelerates to 3%+, driven by investment and exports.
- Further rate cuts totaling 50 basis points by Q3 2026.
Base scenario (50% probability)
- Inflation stabilizes around 5%.
- Growth remains steady near 2%.
- Monetary policy on hold after current easing cycle.
Bearish scenario (20% probability)
- Inflation surprises upward due to commodity shocks.
- Growth slows below 1.50% amid global slowdown.
- Potential rate hike in late 2026 to contain inflation.
Policy pulse
The MPC’s forward guidance emphasizes data dependency, signaling flexibility to tighten if inflationary pressures re-emerge.
Market lens
Forward-looking: Futures markets price a 60% chance of stable rates through mid-2026, with volatility spikes tied to global risk events.
South Africa’s latest interest rate cut to 4.50% reflects a cautious but constructive monetary stance amid easing inflation and steady growth. The central bank balances growth support with vigilance against external shocks. Fiscal discipline and global commodity trends remain key to sustaining this positive momentum.
Investors should monitor inflation data, fiscal updates, and geopolitical developments closely. The rand’s recent stability and bond market response suggest confidence but also sensitivity to global risk shifts.
Overall, the MPC’s decision aligns with a pragmatic approach to navigating a complex macroeconomic landscape, offering a cautiously optimistic outlook for South Africa’s economy.
