Drivers this month
Stronger export receipts from mining and agriculture sectors.
Moderate rand appreciation improving valuation of foreign assets.
Central bank interventions to stabilize currency volatility.
Policy pulse
The South African Reserve Bank (SARB) continues to maintain a cautious monetary stance, balancing inflation control with external liquidity needs. The reserve build-up supports SARB’s ability to defend the rand amid global financial tightening.
Market lens
Immediate reaction: The ZAR/USD pair strengthened by 0.40% within the first hour post-release, reflecting improved investor confidence in South Africa’s external position.
Foreign exchange reserves are a critical macroeconomic indicator reflecting a country’s ability to meet external obligations and stabilize its currency. South Africa’s reserves at ZAR 72.07 billion represent a 0.73 billion month-on-month (MoM) increase and a 8.80% rise compared to the 12-month average of approximately ZAR 66.20 billion.
Monetary policy & financial conditions
The SARB’s repo rate currently stands at 7.25%, with inflation hovering near the 4.50% midpoint target. The reserve accumulation provides the central bank with greater firepower to intervene in forex markets if needed, reducing volatility and supporting financial stability.
Fiscal policy & government budget
South Africa’s fiscal deficit remains elevated at 5.80% of GDP, constraining government borrowing capacity. However, the reserve increase eases external financing risks, especially as the government seeks to refinance debt amid tighter global credit conditions.
External shocks & geopolitical risks
Global uncertainties, including commodity price volatility and geopolitical tensions in key trade regions, pose downside risks. The reserve buffer helps mitigate sudden capital outflows or trade disruptions, though prolonged shocks could strain reserves.
South Africa’s foreign exchange reserves increased to ZAR 72.07 billion in December 2025, up from ZAR 71.55 billion in November and well above the 12-month average of ZAR 66.20 billion. This marks a steady upward trajectory since March 2025, when reserves stood at ZAR 66.26 billion.
The monthly gain of ZAR 0.73 billion reflects improved export earnings and central bank interventions to stabilize the rand. The chart below illustrates this positive trend, highlighting the resilience of South Africa’s external liquidity position amid global financial tightening.

Looking ahead, South Africa’s foreign exchange reserves face a mix of opportunities and risks. The base case scenario projects continued moderate reserve growth to ZAR 74 billion by mid-2026, supported by stable commodity prices and controlled inflation.
Bullish scenario (30% probability)
Stronger global demand for South African exports boosts reserves above ZAR 75 billion.
Commodity price shocks or geopolitical risks trigger capital flight.
Reserves decline below ZAR 70 billion, pressuring the rand.
Fiscal slippage increases external vulnerability.
Policy pulse
The SARB is expected to maintain a vigilant stance, ready to deploy reserves to curb excessive rand volatility. Fiscal reforms remain critical to sustain reserve growth and external stability.
South Africa’s foreign exchange reserves have shown a commendable recovery in 2025, reaching ZAR 72.07 billion in December. This improvement strengthens the country’s external buffers amid a challenging global environment. While risks from geopolitical tensions and fiscal pressures persist, the current reserve trajectory supports a cautiously optimistic outlook for 2026.
Maintaining this momentum will depend on continued export growth, prudent monetary policy, and fiscal discipline. Investors and policymakers alike should monitor external shocks closely, as these remain the primary threat to South Africa’s external stability.
