South Africa’s persistent cost-of-living pressures are squeezing household purchasing power, raising concerns about consumer spending, debt sustainability and the strength of the country’s economic recovery.
Although inflation has moderated from the highs recorded in recent years, the cumulative increase in essential costs means households continue to have less disposable income available for non-essential goods and services.
Consumer inflation accelerated to 5% in June, driven largely by food, fuel and other essential expenses. The South African Reserve Bank subsequently kept the prime lending rate at 10.5%, providing some stability for consumers and businesses with debt, but offering limited relief to heavily indebted households.
Reserve Bank Governor Lesetja Kganyago has warned that persistent inflationary pressures could require further interest rate increases, while a more favourable inflation outlook could create room for rates to ease.
For businesses, the pressure on household finances matters because weaker disposable income can translate into more cautious consumer spending.
Essential costs outpace inflation
The Competition Commission’s latest Cost of Living Report highlights the extent to which administered prices have increased over recent years.
Between 2020 and January 2026, electricity prices rose by about 85%, while water prices increased by approximately 68%. Overall inflation increased by around 30% during the same period.
The sharp rise in utility costs has implications beyond household budgets. Higher electricity and water expenses increase operating costs for businesses and can feed into the prices of goods and services.
Competition Commissioner Doris Tshepe has called for greater scrutiny of administered price-setting mechanisms, warning that persistent cost pressures could limit improvements in household welfare and slow economic recovery.
Food costs squeeze consumer demand
Food remains another critical pressure point for consumers and retailers.
The Pietermaritzburg Economic Justice and Dignity Group’s June Household Affordability Index found that its average household food basket cost R5,502.42, up 1.1% year on year.
However, the cost of a basic nutritious diet for a family of seven was considerably higher at R6,705.31.
The gap illustrates the challenge facing low-income consumers, who have limited flexibility when prices rise. For retailers and consumer-facing businesses, this can result in customers switching to cheaper products, reducing quantities purchased or prioritising essential goods over discretionary spending.
Debt limits household spending power
Rising debt repayments are adding another constraint on consumer demand.
DebtBusters’ Money Stress Tracker found that the cost of living has overtaken interest rates as consumers’ biggest source of financial stress.
Based on responses from 18,000 South Africans, the survey found that 72% of respondents were experiencing financial stress, while more than half were spending over 40% of their take-home pay servicing debt.
DebtBusters executive head Benay Sager said short-term financial survival was increasingly taking priority over longer-term financial planning.
This creates a difficult environment for businesses reliant on discretionary consumer spending, as households with high debt-servicing costs have less capacity to absorb price increases or spend on non-essential products.
Housing affordability remains a challenge
The property market is also reflecting the pressure on household incomes.
BetterBond’s latest Property Brief found that the average purchase price for a first-time buyer reached R1.4 million in the second quarter of 2026, up 9% year on year.
First-time buyers now earn 64% more than the average formal-sector worker, highlighting the widening affordability gap between property prices and household incomes.
Meanwhile, the PayInc Net Salary Index showed that the average real net salary fell to R20,262, down 2.8% from May 2025.
The combination of slower real income growth, higher living costs and elevated borrowing costs continues to make major purchases such as homes and vehicles more difficult for many consumers.
Businesses face a tougher consumer environment
The financial strain is already changing consumer behaviour.
TransUnion’s latest Consumer Pulse Study found that 39% of South Africans expected to miss at least one bill or loan repayment, while consumers were becoming more cautious about spending, borrowing and saving.
Budget Insurance’s Financial Health Survey found that more than half of respondents could not afford to save, while one in six reported reducing or skipping meals to make their money stretch further.
For businesses, these trends point to a consumer market where affordability is becoming increasingly important.
Companies may face greater pressure to keep prices competitive, offer value-driven products and services and respond to customers who are trading down or postponing purchases.
Economic recovery at risk
The broader concern is that persistent household financial stress could weigh on economic growth.
When a larger share of income is absorbed by food, electricity, transport, housing and debt repayments, households have less money available for discretionary consumption, savings and investment.
This creates challenges for businesses already operating in an environment of subdued economic growth.
The Credit Association of South Africa has also warned consumers against taking on multiple small credit commitments that can collectively become an unaffordable monthly burden.
For the economy, the challenge is therefore not simply bringing headline inflation under control. Businesses and policymakers must also contend with the accumulated impact of years of rising essential costs on household purchasing power.
Until income growth consistently outpaces the cost of necessities, many South African consumers are likely to remain focused on financial survival rather than increasing discretionary spending — limiting one of the key drivers of broader economic growth.
