South African households are losing ground. Electricity, water, transport, food and communications costs are all rising faster than overall inflation, and a new Competition Commission analysis warns that ordinary families may see no relief even if global market conditions improve.
The commission’s cost of living report, released this year, documents how the first half of 2026 brought compounding pressures across every essential service. Electricity prices jumped 8.1% between July of the previous year and July 2026. Water costs surged 10.1%. Both figures far outpaced the overall inflation rate of 4.3%, meaning households dependent on these utilities are losing purchasing power month after month.
Petrol prices climbed 26% between January and July alone, driven by geopolitical turbulence in oil markets tied to Middle East conflict. That spike rippled through the entire economy, pushing up minibus taxi fares by 13% over the same period. The burden extended well beyond vehicle owners to the millions who rely on public transport to reach work and essential services.
Communication costs added another layer of strain. Wireless internet service prices increased 4.1% between January and July 2026, exceeding the inflation rate of 3.8% for that period. For households already stretched thin, each increase compounds the others, leaving less money for food, medicine and other necessities.
The food sector reveals a troubling pattern. While production costs for some staple items have fallen significantly, retail prices have not followed. The commission found that producer prices for bread, sunflower oil and maize meal remain elevated despite substantial declines in the cost of wheat, sunflower seed and maize. Retail prices for individually quick-frozen chicken and canned pilchards have similarly failed to reflect stable or declining producer prices. Producer prices for eggs increased substantially since the start of the year, yet consumers saw no corresponding benefit.
This disconnect points to what the commission calls “rocket and feather” pricing strategies, in which prices rise quickly when input costs climb but fall slowly, or not at all, when those costs decline. The regulator expressed concern that once fuel prices stabilize, food prices may remain stubbornly high rather than adjusting downward to reflect lower production expenses.
Meanwhile, the government has begun to respond. Trade, industry and competition minister Parks Tau announced in December that the commission had identified agriculture, food and agro-processing as priority sectors for monitoring. The commission is undertaking a joint project with the department of agriculture to compare South Africa’s profit margins and price spreads for zero-rated food products with those in selected other countries, focusing on breads, maize and maize products, tinned fish, milk and milk products and vegetable oil.
The commission’s monitoring work began in July 2020, tracking staple food prices from farm to retail. It has since expanded to cover electricity, water, housing, health care, transport, education and communication services, as well as the impact of interest rates on household affordability.
For vulnerable populations, municipal indigent support programmes offer some protection. The commission warns, however, that these safety nets are insufficient. Affordability pressures persist where tariff increases exceed inflation and where the poorest households are not effectively reached by existing assistance mechanisms. The regulator called for greater transparency and consistency in how tariffs are set, stronger oversight of water supply chains, improved infrastructure investment and incentives for operational efficiency.
Without these changes, the commission said, future tariff increases risk placing excessive burdens on households already struggling to meet basic needs. Whether the joint monitoring project with the agriculture department will translate into meaningful price relief at the retail shelf remains the question families across the country are waiting to have answered.
