South Africa has raised its main lending rate for the first time in three years, as rising global energy costs linked to the Iran conflict intensify inflation pressures and force policymakers to tighten monetary conditions.
The South African Reserve Bank increased its benchmark repo rate by 25 basis points to 7.00 percent, in a move aimed at containing inflation expectations and stabilising price pressures.
Governor Lesetja Kganyago said the decision reflected growing concerns that external shocks including higher oil prices and geopolitical tensions — were beginning to feed into broader domestic inflation dynamics.
He said the Monetary Policy Committee (MPC) agreed that inflation risks had intensified and that overlapping global shocks could trigger second-round effects across the economy.
The decision was not unanimous. Four members voted in favour of the rate hike, while two preferred to keep rates unchanged. Policymakers also considered a larger 50-basis-point increase but opted for a more cautious approach.

South Africa’s central bank said inflation had accelerated sharply in April, moving toward the upper end of its target range, prompting the need for pre-emptive action.
The Reserve Bank also raised its inflation forecasts for 2026 and 2027 to 4.4 percent and 3.7 percent respectively, up from previous projections of 3.7 percent and 3.3 percent.
At the same time, it revised down its economic growth outlook, cutting projections to 1.2 percent for 2026 and 1.7 percent for 2027, citing weaker domestic demand and tighter financial conditions.

The central bank maintains an inflation target of 3 percent, with a tolerance band of one percentage point either side.
Analysts say the rate hike reflects a broader global trend among some emerging market central banks responding to imported inflation pressures, particularly those linked to energy market disruptions.
Since the escalation of tensions in the Middle East, several central banks — including those in Rwanda, Botswana and Mauritius — have also tightened monetary policy in response to rising inflation risks.
The South African Reserve Bank warned of multiple risk scenarios, including a prolonged geopolitical crisis combined with adverse weather conditions and stronger-than-expected inflation persistence.
In its most severe scenario, inflation could rise above 6 percent, potentially requiring additional interest rate hikes to bring price growth back within target.
Economists say the move signals a shift toward a more defensive monetary stance as South Africa seeks to protect price stability amid a volatile global environment, even at the cost of slower growth.
