Rising transport costs push South Africa inflation to three-month high

South Africa’s annual inflation rate rose for a second consecutive month in September, as a sharp increase in fuel prices pushed up transport costs and added pressure to household budgets.

Consumer price inflation climbed to 4.5 percent from 4.4 percent in August, according to Statistics South Africa, although the increase was smaller than the 4.7 percent expected by economists. The September reading was the highest in three months, leaving inflation above the South African Reserve Bank’s three percent target and the upper limit of its two percent to four percent tolerance band.

Transport prices were the biggest contributor to the increase, rising by 10.8 percent year on year, compared with 8.8 percent in August. The acceleration largely reflected higher fuel prices following domestic price increases, with fuel inflation reaching 27.9 percent from 20 percent a month earlier.

Diesel prices jumped by 46 percent, while petrol prices rose by 25 percent, highlighting the pressure from higher energy costs in an economy that imports most of its fuel and remains exposed to movements in global oil prices.

The increase in inflation comes as the Iran war, which broke out in late February, has heightened uncertainty in energy markets and left fuel-importing economies vulnerable to price shocks.

Fuel prices drive transport inflation

Transport remained the largest contributor to South Africa’s annual inflation rate in September, adding 1.5 percentage points to the overall 4.5 percent reading, according to Statistics South Africa.

Housing and utilities were the second-largest contributor, with prices rising by 5.2 percent and adding 1.3 percentage points. Insurance and financial services increased by 5.4 percent, contributing a further 0.6 percentage points.

Food inflation also edged higher, rising to 1.2 percent in September from 1.1 percent in August. Although the increase was modest, higher food prices add to the pressure on households already facing rising transport and other living costs.

On a monthly basis, consumer prices rose by 0.4 percent in September after remaining unchanged in August, indicating a renewed increase in the overall cost of goods and services.

The figures show that fuel and transport costs were the main drivers of the latest inflation increase, even as price pressures in some other parts of the economy eased.

Core inflation eases as services prices slow

Core inflation, which excludes food, non-alcoholic beverages, fuel and energy, edged down to 4.0 percent in September from 4.1 percent in August. The decline suggests that underlying price pressures eased slightly despite the increase in headline inflation.

The breakdown between goods and services also showed differing trends. Annual goods inflation accelerated to 4.1 percent from 3.3 percent in August, while services inflation slowed to 4.9 percent from 5.1 percent.

The divergence suggests that rising prices for goods, including those affected by fuel and transport costs, contributed to the acceleration in headline inflation, while price increases in services moderated.

For the South African Reserve Bank, the combination of higher headline inflation and slightly lower core inflation presents a mixed picture. A sustained rise in fuel prices could feed into transport, production and distribution costs, potentially putting further pressure on prices across the economy. However, the easing in core and services inflation points to some moderation in underlying pressures.

The September figures leave inflation above the central bank’s target, with the direction of global energy prices likely to remain an important factor in the months ahead.
