While South Africa’s headline inflation eased sharply to 4.3% year on year in July, down from 5% in June and below the 4.5% consensus forecast, and while this improvement was driven mainly by lower transport and food inflation, following July’s substantial fuel-price cuts, Momentum's group economist, Sanisha Packirisamy cautions that the improvement may not last.

With South Africa’s July Consumer Price Index (CPI) inflation data released by Statistics South Africa on Wednesday, 19 August 2026, Packirisamy says the latest CPI results indicate inflation is easing, but household pressure is not over.
"Global diesel supply is under pressure because of refinery disruptions, export restrictions and lower inventories, with September estimates pointing to a R2.75/l increase in diesel and 79c/l increase in petrol. This could feed through into transport and eventually food prices," she says.
"This, even while food inflation fell to just 0.6%, helped particularly by lower meat, bread and cereal prices, and while strong domestic agricultural production and a stronger rand have helped contain food costs. Here she unpacks what July’s CPI means for households and the inflation outlook.
July’s 4.3% inflation reading was significantly better than expected. How sustainable is this improvement, or are we likely to see inflation pick up again in the coming months?
The below-consensus July reading offers reason for optimism, though we would avoid projecting it as a continuous downward trajectory just yet. A major contributor to the lower figure was the rapid decline in pump prices (petrol dropped 7.1% and diesel sank 11.7% month-over-month), easing transport costs significantly.
However, these gains are short-lived. Diesel has already rebounded in August, and substantial price increases are lined up for September. Beyond energy, broader inflationary pressures remain sticky. Services inflation held steady at 5.0% year-on-year, and housing and utilities came in at 5.2%. We view July as a brief retreat in headline inflation rather than the start of a clear path down. We expect inflation to lift in the near term before finding a more stable downward path.
Diesel prices are expected to rise sharply in September despite lower crude oil prices. How quickly could this feed through into transport costs and, ultimately, consumer prices?
Higher diesel prices deliver an immediate blow to transport and operational budgets. The spill over into retail and grocery shelves takes longer to materialise, however, as businesses typically cushion the initial shock through existing contracts or squeezed margins.
What makes the current market unusual is that crude oil isn't the only driver. Severe supply bottlenecks in global refining, fuelled by outages in Russia and the Middle East, have left diesel stocks exceptionally tight. Consequently, diesel prices can remain stubbornly high even when crude oil prices soften.
Food inflation has fallen to just 0.6%. How much longer can consumers expect this relief, given the higher fuel and fertiliser costs and the risk posed by El Niño?
Good domestic harvests have been an important buffer, while cereal prices have fallen and meat inflation has moderated sharply. Consumers shouldn't count on local food prices staying this benign over the medium to longer term though. Surging diesel and fertiliser bills are beginning to weigh on farmers heading into the upcoming summer planting season.
Meanwhile, the World Meteorological Organisation assigns an estimated 90% probability to El Niño conditions developing later this year. Food inflation could begin creeping upward near year-end, with a sharper impact likely in 2027 if El Niño disrupts rainfall and hits crop yields.
Municipal costs continue to rise faster than headline inflation. What does this tell us about the difference between the official inflation rate and the cost pressures households are actually experiencing?
Headline CPI tracks a standard market basket across the broader economy, but no two household budgets look identical. Unavoidable expenses like municipal tariffs hit particularly hard because families can't easily cut back on or swap them out like discretionary spending, which skews how everyday consumers actually experience inflation.
It's also critical to separate the rate of inflation from absolute price levels. Slower inflation simply means costs are rising less quickly, not that life is getting cheaper because multi-year, above-inflation hikes in water, electricity and insurance means that households are absorbing new increases on top of an already elevated baseline.
Does the latest inflation data strengthen the case for the Sarb to cut interest rates later this year, or do the current upside risks make a rate cut unlikely?
While the soft July inflation print strengthens the case for monetary easing, a single favourable data point is unlikely to trigger an immediate rate cut from the Sarb. To build confidence for a rate-cutting cycle, policymakers will need to see several favourable conditions align, including persistent relief in fuel prices, a stable rand, anchored inflation expectations (at a lower level) and unambiguous proof that core and services inflation are trending lower.
How significant is the Middle East conflict for South Africa’s inflation outlook, particularly through fuel, transport and food prices?
Global energy volatility is a major external threat to South Africa's inflation trajectory. As a net importer of crude oil and refined petroleum, South Africa feels the sting of international price swings almost immediately at the pump. These fuel hikes ripple through the broader economy, raising freight and production expenses, given the country's heavy reliance on road transport to haul the vast majority of its goods.
A prolonged disruption in the Strait that extends into South Africa's planting season can also begin affecting fertiliser costs, agricultural production and eventually food inflation as well.
Looking ahead over the next 12 months, what do you see as the biggest risk to inflation — and what would need to happen for South Africans to experience a more meaningful improvement in their cost of living?
As the Sarb has indicated, the primary threat isn't a single isolated event, but rather the compounding effect of multiple supply disruptions hitting simultaneously.
A drawn-out Middle Eastern conflict could keep diesel and fertiliser costs elevated just as El Niño begins taking a toll on farming conditions. At the same time, municipal charges and other administered prices are running far ahead of the Sarb’s inflation target, compounding the pressure on the domestic economy.
