South Africans are bracing for another interest rate hike as fuel prices surge, potentially pushing inflation towards 5% year-on-year and increasing the cost of debt and everyday essentials. This comes after a steep increase in fuel prices, with petrol rising by between R3.12 and R3.33 per litre and diesel by R2.84 to R3.24 per litre.
According to Investec chief economist Annabel Bishop, the recent fuel price hikes are likely to fuel another interest rate hike in November. Inflation stood at 4.4% in August, slightly up from July's rate, with transport costs increasing by 8.8% year-on-year. Bishop attributed the fuel price concerns to the ongoing conflict in the Middle East and its potential impact on oil supply and prices.
The possible interest rate hike would add to the financial burden of households already struggling with high debt levels. The South African Reserve Bank's Quarterly Bulletin shows household debt at 62.2% of disposable income in the first quarter, with debt servicing costs at 8.4%. A 0.25 percentage point hike would increase the prime rate to 11%, affecting households with mortgages and car loans.
For households with a R1.5 million home loan over 20 years, a 25 basis-point hike would increase monthly repayments by R255, while a R500 000 car financed over six years would see an increase of R64 per month. This would add to the financial strain on households, with DebtBusters' 2026 Money-Stress Tracker finding that 53% of respondents spend more than 40% of their take-home pay on debt repayments.
The fuel price shock is also affecting the transportation of food and goods, with the Road Freight Association estimating a 4-6% rise in freight operating costs due to the diesel price increase. As fuel accounts for 35-55% of road-freight companies' operating costs, this could have a ripple effect on the prices of goods and food.
However, PSG senior economist Johann Els noted that there has been little visible feed-through from higher petrol and diesel prices into food and other consumer goods so far. Instead, consumers may experience a substitution effect, where they spend more on fuel and transport and less elsewhere, potentially creating deflationary forces.
Despite this, the cost of a food basket, as measured by the Pietermaritzburg Economic Justice and Dignity Group's Household Affordability Index, has increased by 2% year-on-year to an average of just under R5 500. The average cost of prioritized foods in the household food basket rose by 2.9% year-on-year, adding to the financial strain on households.
