South Africans could soon face another wave of food price increases as rising fuel and diesel costs begin filtering through the country’s supply chain, with economists and retailers warning that household affordability may come under growing pressure during the coming months. The warnings come as new affordability data shows the average household food basket increased again in April, while major retailers say suppliers have already started notifying them about upcoming price hikes.
The concerns are particularly significant for Gauteng residents, where many households rely heavily on supermarket purchases, public transport and fuel-dependent supply chains for daily living. Analysts say continued increases in food and transport costs may place additional pressure on already strained household budgets across the province.
Industry groups and economic analysts are now warning that prolonged food inflation could have wider economic and social consequences if costs continue escalating.

Food Basket Prices Rise Again in April
According to the Pietermaritzburg Economic Justice and Dignity Group’s latest Household Affordability Index, the average household food basket increased by R123.56 in April to reach R5 452.09.
The organisation linked the increases to rising fuel prices and broader geopolitical tensions affecting global energy markets.
The report warned that escalating food costs could eventually create wider food security concerns if price increases continue accelerating.
Several essential grocery items recorded increases during April, including:
- Onions: up 23%
- Tomatoes: up 10%
- Fish: up 8%
- Carrots: up 5%
- Rice: up 4%
- Sugar beans: up 4%
- Cooking oil: up 2%
Economists say staple food increases often hit lower and middle-income households hardest because food makes up a significant portion of monthly spending.
Diesel Costs Starting to Affect Food Prices
Retailers and analysts say diesel prices are becoming one of the biggest risks to future food inflation.
South Africa’s economy depends heavily on diesel-powered logistics, transport and supply chain systems to move goods between farms, factories, warehouses and supermarkets.
According to the Pietermaritzburg Economic Justice and Dignity Group, South Africa imports between 70% and 80% of its fuel requirements, while much of the diesel consumed locally is imported as finished product.
The report noted that food transported across long distances becomes more expensive when fuel prices rise.
Economic analysts say Gauteng is especially vulnerable because of the province’s dependence on large-scale food distribution systems feeding densely populated urban areas.
Retailers Warn More Increases Could Follow
Retail group Boxer has also warned that food price increases are likely to continue later in the year.
According to Boxer CEO Marek Masojada, suppliers have already informed the retailer about pending price increases expected to affect multiple categories.
“We are receiving notice from many of our suppliers of pending price increases,” Masojada said.
The retailer said higher diesel and fuel costs are expected to gradually work their way through the supply chain before eventually affecting prices paid by consumers at supermarkets.
Analysts say rising fuel prices can affect:
- Food transportation
- Packaging costs
- Refrigeration and storage
- Retail operating expenses
- Delivery and logistics networks
The impact may become more visible during winter as households already face increased electricity and heating expenses.
Gauteng Consumers May Feel the Pressure Faster
Gauteng households may experience food inflation more sharply because of the province’s urban spending patterns and transport dependency.
Most residents purchase food directly from supermarkets and retail chains rather than through local agricultural supply systems.
The affordability report warned that many South Africans operate on “just-in-time” household buying patterns, where families purchase food only when money becomes available instead of storing larger reserves at home.
This means rapid price increases can immediately affect household affordability.
Consumer experts say rising food prices may also change shopping behaviour across Gauteng as residents attempt to stretch monthly budgets further.
Retailers Expect Consumer Shopping Habits to Shift
Retailers believe higher transport and fuel costs may change how consumers shop during the coming months.
According to Boxer CEO Marek Masojada, households may begin:
- Making fewer shopping trips
- Buying larger baskets less frequently
- Prioritising cheaper brands
- Reducing non-essential spending
Retailers are also attempting to absorb some operational increases internally before passing costs onto customers.
However, industry analysts warn that prolonged fuel increases may eventually make this difficult.
Food Security Concerns Raise Broader Economic Questions
The Pietermaritzburg Economic Justice and Dignity Group warned that severe food inflation could eventually create wider social and economic risks.
The organisation referenced the July 2021 unrest while discussing the potential consequences of food insecurity and affordability pressure.
Analysts say food affordability is closely linked to:
- Household stability
- Public confidence
- Consumer spending
- Economic participation
- Social stability
Government and industry stakeholders are expected to continue monitoring pricing trends closely during the coming months.
Electricity and Winter Costs Add More Pressure
The timing of rising food prices may place additional pressure on households already dealing with winter-related expenses.
Many Gauteng residents are simultaneously facing:
- Increased electricity usage
- Rising transport costs
- Debt pressure
- Higher fuel prices
- Winter heating expenses
Economists say lower-income households are often the most vulnerable because food and transport make up a large portion of monthly income.
What This Means for Gauteng Residents
For Gauteng residents, continued increases in food prices may affect household budgets, shopping habits and monthly living costs.
Urban households relying heavily on supermarket purchases and public transport may feel the effects particularly quickly if fuel and diesel costs continue rising.
Rising prices on staple foods may also place pressure on vulnerable households already managing high electricity, transport and debt costs during winter.
Industry analysts say food affordability is likely to remain a major economic concern throughout 2026 if global fuel pressures continue affecting supply chains.
