South Africa’s Prime Overdraft Rate (POR) was lowered to 10.25% on November 20, 2025, according to the latest release from the Sigmanomics database. This marks a 25 basis point cut from the previous 10.50% recorded in September 2025, continuing a downward trend from the peak of 11.75% in early 2024. The rate now stands near its lowest level in nearly two years, reflecting a monetary policy pivot amid evolving macroeconomic conditions.

Drivers this month

• Inflation easing: Consumer Price Index (CPI) slowed to 5.80% YoY in October, down from 6.30% in August.
• Slower GDP growth: Q3 2025 GDP expanded 1.20% YoY, below the 1.80% average of the past year.
• Rand stabilization: ZAR/USD hovered around 17.50, supported by improved trade balances.

Policy pulse

The POR cut aligns with the South African Reserve Bank’s (SARB) inflation target range of 3-6%. The easing signals confidence that inflation pressures are abating, allowing for more accommodative financial conditions to support growth.

Market lens

Immediate reaction: The ZAR strengthened 0.40% against the USD within the first hour post-announcement, while the JSE All Share Index (J203) gained 0.70%. Short-term bond yields declined by 10 basis points, reflecting improved risk appetite.

Core macroeconomic indicators provide context for the POR adjustment. Inflation has moderated steadily from a peak of 7.20% YoY in mid-2024 to 5.80% in October 2025. This easing owes partly to lower global energy prices and subdued domestic demand. Meanwhile, GDP growth remains modest, with Q3 2025 expanding 1.20% YoY, down from 1.80% in Q1 2025 and well below the 3.00% average seen in 2023.

Monetary policy & financial conditions

The SARB’s decision to reduce the Prime Overdraft Rate follows a series of rate hikes that began in early 2024, when the POR was 11.75%. The current 10.25% rate is the lowest since March 2024. Financial conditions have eased, with lending rates declining and credit growth stabilizing at 5.50% YoY. Inflation expectations have also moderated, with breakeven inflation rates on 2-year government bonds falling from 6.50% in mid-2024 to 5.20% recently.

Fiscal policy & government budget

South Africa’s fiscal stance remains cautious. The 2025/26 budget projects a deficit of 5.10% of GDP, slightly improved from 5.50% in 2024/25. However, rising debt servicing costs and slow revenue growth constrain fiscal space. Structural reforms aimed at improving tax collection and reducing state-owned enterprise losses are ongoing but face implementation risks.

Drivers this month

• Inflation deceleration contributed 0.15 percentage points to the rate cut.
• Slower GDP growth added 0.07 percentage points.
• Rand currency stability accounted for 0.03 percentage points.

Policy pulse

The current POR sits comfortably within the SARB’s inflation target corridor, allowing room for further easing if inflation continues to moderate. The policy stance is now more neutral compared to the restrictive levels seen in 2024.

Market lens

Immediate reaction: The JSE All Share Index (J203) rose 0.70%, while the USDZAR pair dropped 0.40% post-announcement, signaling improved investor sentiment and reduced risk premiums.

Looking ahead, the trajectory of the Prime Overdraft Rate will depend on inflation dynamics, growth prospects, and external risks. The SARB has signaled a cautious approach, balancing inflation control with growth support.

Bullish scenario (30% probability)

• Inflation falls below 5% by mid-2026.
• GDP growth accelerates to 2.50% YoY.
• Further POR cuts of up to 50 basis points by Q3 2026.

Base scenario (50% probability)

• Inflation stabilizes around 5.50%.
• GDP growth remains near 1.50%.
• POR holds steady at 10.25% through 2026.

Bearish scenario (20% probability)

• Inflation rebounds above 6% due to commodity shocks.
• GDP growth slows below 1%.
• SARB reverses cuts, raising POR back toward 11%.

External shocks, including geopolitical tensions and commodity price volatility, remain key downside risks. Fiscal constraints and structural bottlenecks could also limit growth and pressure monetary policy.

South Africa’s Prime Overdraft Rate reduction to 10.25% reflects a pivotal shift in monetary policy amid easing inflation and subdued growth. While this move supports credit and investment, external uncertainties and fiscal challenges temper optimism. Structural reforms and prudent fiscal management will be critical to sustaining growth and financial stability.

Market participants should monitor inflation trends, SARB communications, and geopolitical developments closely. The POR’s trajectory will remain a key barometer of South Africa’s economic health and policy stance in the coming year.
