SA feels the heat when the world catches fire

The primary catalyst for the Reserve Bank's rate hike is external

ON MAY 28, 2026, the South African Reserve Bank’s Monetary Policy Committee raised the repo rate by 25 basis points to 7.00% per annum, lifting the prime lending rate to 10.50%, effective the following day.

The four-to-two MPC split tells its own story - this was not a decision taken in consensus, but one driven by the weight of deteriorating global conditions that South Africa neither caused nor controls.

Governor Lesetja Kganyago was direct: inflation risks have intensified, overlapping global shocks risk triggering second-round price effects, and the Bank's mandate required a pre-emptive response. Inflation climbed from 3.1% in March to 4% in April, driven by energy costs and external shocks. The SARB now projects headline inflation to average 4.4% in 2026 and 3.7% in 2027, with a return to the 3% midpoint only by 2028.

The primary catalyst for this rate hike is external. The US-Israeli military campaign against Iran, which commenced in late February 2026, triggered what the International Energy Agency described as the largest energy supply disruption in the history of the global oil market. The near-closure of the Strait of Hormuz - through which approximately 20% of the world’s daily oil trade flows - sent Brent crude surging by more than 25%. For a fuel-importing, rand-denominated economy, the arithmetic is punishing: higher oil prices drive elevated pump prices, higher logistics costs, and broader consumer price inflation.
