• September inflation below Reuters poll forecast of ​4.7%
  • Transport accounts for roughly a third of headline inflation
  • Economists split on ‌mid-November rate decision

South Africa’s inflation rate rose modestly in September, data showed on Wednesday, but economists expect a sharper acceleration in October after fuel prices hit a record high.

Headline ​consumer inflation ticked up to 4.5% year-on-year in September from 4.4% in August, ​moving further away from the central bank’s 3% target. The figure ⁠was below a 4.7% forecast from economists polled by Reuters.

Transport inflation accelerated to ​10.8% from 8.8% in August, making it the largest contributor to the rise and ​accounting for around a third of headline inflation, South Africa’s statistics agency said.

South Africa imports most of its fuel, leaving it vulnerable to swings in global energy prices. Its regulated petrol price rose ​about 5% in September before surging 12% in October.

Economists divided on final 2026 rate decision 

The central bank has raised its policy rate twice since the start of the Iran war, ‌including at ⁠its last meeting in September.

Economists are divided on what the bank will do in mid-November at its one remaining scheduled meeting of 2026.

Nedbank economist Johannes Khosa expects another 25 basis point rate hike as inflation is projected to remain above the central bank’s ​target until at ​least the last quarter ⁠of 2027.

Bureau for Economic Research chief economist Lisette IJssel de Schepper said the bank could keep interest rates unchanged as underlying ​price pressures, reflected in the level of core inflation, are ​relatively contained.

She ⁠said October’s fuel price increase could push overall inflation above 5% at the next release.

Trade unions and some political parties have called for the government to offer fuel price ⁠relief, along ​the lines of the levy reduction between April ​and June.
