The headline rate moved up again

South Africa’s annual consumer price inflation rose to 4.5% in September 2026, from 4.4% in August, according to Statistics South Africa’s release published on 21 October. Prices increased by 0.4% month on month, ending a month in which the overall index had been flat.

The result was below the approximately 4.7% rate anticipated by economists surveyed before the release. That does not mean prices fell: it means the annual pace of increase was slightly slower than expected, while the typical consumer basket still cost more than it did a year earlier.

Transport carries much of the pressure

Transport prices increased 10.8% year on year and contributed 1.5 percentage points to the overall 4.5% inflation rate. The official data also show housing and utilities rising 5.2%, contributing 1.3 points, and insurance and financial services rising 5.4%, adding 0.6 points.

Fuel was a central driver. Stats SA’s September figures show the fuel component up 27.9% from a year earlier and 6.2% from August. Higher fuel costs affect drivers directly and can also raise the cost of moving goods, although the extent and timing of those knock-on effects vary across businesses.

The details are more uneven than one number suggests

Goods inflation increased to 4.1% from 3.3% in August, while services inflation eased to 4.9% from 5.1%. The measure excluding food, non-alcoholic beverages, fuel and energy was 4.0%.

Provincial figures also differ: the Western Cape recorded 5.5% annual inflation, compared with 4.3% in Gauteng and 3.0% in Limpopo. These are price-change rates, not measures of whether a household can afford the goods and services it needs.

What comes next

The September release predates further fuel-price increases in October, meaning it cannot yet show their full impact on the official consumer index. Economists have warned that inflation could rise more sharply in the October data.

Stats SA is scheduled to release the October CPI figures on 18 November, followed by the South African Reserve Bank’s next monetary policy decision on 19 November. The Bank’s inflation target is 3%, and its policy decisions will depend on the broader outlook, not a single monthly figure.
