Despite the widely expected 25-basis-point interest rate hike, there was still a compelling, data-driven case for the South African Reserve Bank (Sarb) to have kept the repo rate on hold.

In the media conference following the announcement, Sarb governor Lesetja Kganyago confirmed that the Monetary Policy Committee (MPC) had seriously considered such a pause, noting that the latest Bureau for Economic Research (BER) survey showed inflation expectations had stabilised in the third quarter and even edged lower for 2027 and 2028.
That case was reinforced by the latest inflation data. Core inflation eased to 4.1% year-on-year in August, from a two-year high of 4.2% in July, while the month-on-month rate remained unchanged.
"It suggests that underlying price pressures remain largely contained, despite the slight upward nudge in headline inflation. Although headline inflation may rise further in the months ahead, it seems likely to average about 4.4% for 2026 as a whole," said Raymond Parsons, North-West University Business School economist.
With the MPC having made its final decision to hike interest rates, the reality is that the “higher-for-longer” outlook is likely to be extended in the period ahead, inevitably coming at a cost to economic activity, Parsons stressed.
“In these difficult times, therefore, a further rise in borrowing costs will have a negative impact on business and consumer confidence at a time when the economy is struggling to regain momentum.
“Elevated interest rates reduce disposable income and raise the cost of capital when South Africa’s already vulnerable GDP growth projections need support.”
The 25-basis-point increase adds to a range of affordability pressures that have steadily eroded purchasing power throughout 2026.
"While inflation has moderated, many households have yet to experience meaningful relief in their monthly finances," said Lee Naik, chief executive officer and regional president of TransUnion Africa.
Consumers are warned to brace for impact. "A 25-basis point increase is expected to raise monthly repayments on a R1m home loan by approximately R160 to R170 per month, while repayments on a R2m home loan could increase by around R320 to R340 per month. A consumer financing a R400,000 vehicle could see repayments increase by approximately R65 per month," Naik said.
Although relatively modest in isolation, these additional costs arrive at a time when households are already contending with high living expenses and tighter budgets.
Households under pressure
According to the South African Reserve Bank's June 2026 Quarterly Bulletin, household debt-to-disposable income increased from 61.8% in Q4 2025 to 62.2% in Q1 2026, while debt-service costs remained elevated at 8.4% of disposable income. Statistics South Africa's quarterly Labour Force Survey reported that unemployment increased to 33.6% in Q2 2026, while youth unemployment reached 47.4%, highlighting the continued pressure on income growth.
TransUnion said it expected consumers to respond by reducing discretionary spending, reassessing household budgets and delaying major purchases, prioritising debt obligations and essential expenses.
"Demand for flexible credit solutions and financial-management tools may also increase as households seek to preserve cash flow," said Naik. "While vehicle finance and mortgage-repayment performance have remained relatively resilient, TransUnion cautions that additional monetary tightening could place renewed pressure on repayment performance, particularly within unsecured lending segments where delinquency rates remain elevated."
Resilience meets reality
Nevertheless, South African households remain resilient.
"According to TransUnion's Q2 2026 Consumer Pulse Study, consumers continue to adapt to financial pressure through behaviourial changes. 52.7% of consumers have reduced discretionary spending, 63.4% actively seek discounts and promotions, 44.2% shop at lower-cost retailers, 38.8% expect difficulty paying future bills and loans, while a proportion are drawing down savings and increasingly relying on credit products and flexible payment solutions to manage daily expenses," Naik added.
Despite this demonstration of staying power, affordability remains fragile and increasingly sensitive to further cost increases.
"Today's rate increase adds pressure to households already facing elevated fuel costs, transport expenses and ongoing affordability challenges," Naik cautioned.
"Consumers are not facing a new problem, but a deepening of pressures that already exist.”
