Is the rising cost of living significantly impacting your household budget?

South Africa's annual consumer price index inflation reached 4.5% in September 2026, marking an increase from 4.4% recorded in August 2026. The monthly index also grew by 0.4% during this period.

Why it matters

Higher fuel prices served as a primary driver of inflation, with transport costs accounting for a third of the overall increase. This shift highlights how energy-sensitive sectors continue to influence the broader cost of living.

The consumer price index rose 0.4% month-on-month, while annual passenger transport inflation climbed to 12.3%. It remains to be seen how persistent fuel price pressures will affect aggregate inflation in the coming quarter.

The details

Transport costs were the significant factor, fuelled by a 6.2% monthly increase in the fuel price index. While fuel pushed transport prices higher, cereal products provided some relief by recording an annual deflation rate of -1.9%.

March 2025: Meat inflation reached 0.4%.
Q2 2026: Annual rental inflation was 4.1%.
August 2026: CPI inflation stood at 4.4%.
September 2026: CPI inflation reached 4.5%.
Q3 2026: Annual housing rental inflation declined to 3.9%.

Macro View

The current 4.5% inflation rate provides a concrete benchmark for evaluating the South African Reserve Bank's established target range. This update shows how the economy is currently positioning itself relative to long-term monetary policy goals.

The rise in passenger transport costs and fuel prices may directly impact monthly commuting budgets for families. While lower cereal prices provide minor relief, the broader inflation trend necessitates careful management of household spending.

The takeaway

Transport cost volatility remains a significant factor in the monthly cost of living. Consumers should adjust their travel budgets to account for ongoing fluctuations in fuel prices and passenger transport services.
