Consumer price inflation in South Africa rose to 4.1% year-on-year in March 2026, according to figures released by Statistics South Africa, with the transport and food categories leading the upward pressure and analysts already warning that the April fuel price adjustment will drive the measure meaningfully higher in the months ahead.
The March reading represents an increase from February’s 3.8% and is the highest CPI print since mid-2025, ending a period of relative price stability that had allowed the South African Reserve Bank to cut interest rates in both November 2025 and February 2026. The timing is uncomfortable for the MPC, which had been considering further accommodation before the sudden deterioration in the energy price outlook.
Food price inflation came in at 5.6% year-on-year in March, driven by the lagged effects of higher diesel costs on the agricultural supply chain. Bread, maize meal, and cooking oil all recorded above-average monthly price increases, disproportionately affecting lower-income households that spend a larger share of their budgets on staple foods.
Housing, water, electricity and fuel — the largest component of the CPI basket — rose 5.3% year-on-year, as the approved Eskom tariff increases and municipal service hikes began reflecting fully in the index for the first time.
Chief economist at the Bureau for Economic Research, writing in a client note, estimated that the April fuel increase alone could add between 0.5 and 0.8 percentage points to headline CPI when the May figures are published, potentially pushing inflation above 5% for the first time since 2023 and firmly outside the comfortable mid-point of the Reserve Bank’s 3%-6% target range.
