South Africa’s central bank governor Lesetja Kganyago has reaffirmed the Reserve Bank’s commitment to bringing inflation back to its 3 percent target, defending last week’s interest rate increase as necessary to prevent broader price pressures from taking hold.
The South African Reserve Bank (SARB) raised its benchmark repo rate by 25 basis points to 7 percent last Thursday, in a decision supported by four of the six members of its Monetary Policy Committee.
Inflation in Africa’s most industrialised economy rose to 4 percent in April, up from 3.1 percent in March, placing it at the upper end of the bank’s 3–6 percent target range.
Kganyago said the rate hike was aimed at containing “second-round effects” from rising global oil prices, driven by tensions in the Middle East, which have pushed up transport, food and production costs.
South Africa is a net importer of oil and has been particularly exposed to recent increases in global energy prices, although government fuel levy adjustments have partially cushioned the impact on consumers.
The central bank raised its inflation forecasts to 4.4 percent for 2026 and 3.7 percent for 2027, reflecting expectations that price pressures could remain elevated in the medium term.
Kganyago warned that higher diesel and fertiliser costs could spill over into food prices, increasing the risk of broader inflationary persistence across the economy.
He said inflation expectations remained vulnerable to upward pressure, noting that businesses and consumers still have recent memories of high inflation episodes, which could influence pricing behaviour.
“By changing rates, we hope to send a clear and credible signal that we will keep inflation under control,” Kganyago said in a speech in Johannesburg, adding that the central bank would not allow a wage-price spiral to develop.
He stressed that protecting price stability was essential to safeguarding vulnerable households, who are most affected by rising living costs.
The governor also ruled out a return to the previous 3–6 percent inflation targeting band, signalling continued commitment to the current framework.
Analysts say the Reserve Bank’s tightening stance reflects growing concern over imported inflation risks, particularly from volatile energy markets linked to geopolitical tensions involving Iran and broader Middle East instability.
South Africa’s inflation trajectory is closely watched by investors, as it influences monetary policy direction, bond yields and currency performance in Africa’s largest economy.
The next inflation expectations survey, which will provide further insight into pricing behaviour across the economy, is expected to be released at the end of June.

Background to South Africa’s inflation
South Africa’s monetary policy tightening comes against a backdrop of rising global energy prices and persistent structural inflation pressures in the domestic economy. As a net oil importer, the country is particularly vulnerable to external shocks, with fuel price increases feeding directly into transport costs, food inflation and broader consumer prices.
Inflation in South Africa has recently moved higher after a period of relative stability, prompting renewed concern at the South African Reserve Bank (SARB) that price pressures could become entrenched. The central bank operates under an inflation-targeting framework of 3 percent with a 1 percentage-point tolerance band, which it uses as a guide for interest rate decisions.
Recent spikes in global oil prices, linked to geopolitical tensions in the Middle East, have added new pressure to inflation expectations. Higher diesel and fertiliser costs are especially important in South Africa, where food prices are highly sensitive to transport and input costs.
At the same time, economic growth remains weak, creating a difficult policy trade-off for the central bank. While higher interest rates help contain inflation, they also risk slowing already subdued consumer spending and investment.
The Reserve Bank’s decision to raise rates reflects its concern that inflation expectations could rise if price shocks are not contained early. Policymakers have repeatedly stressed the importance of maintaining credibility in the inflation-targeting regime to avoid a return to higher, more volatile inflation seen in previous cycles.
This context explains Governor Lesetja Kganyago’s firm messaging that the bank will not tolerate a price spiral, even as external shocks continue to influence domestic price dynamics.
