TransUnion South Africa says today's decision by the South African Reserve Bank's Monetary Policy Committee to increase interest rates by 25 basis points reflects ongoing concern around inflation risks and inflation expectations. However, the increase comes at a time when many households remain under significant affordability pressure.

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.

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 and household resilience.

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

"Consumers have demonstrated remarkable resilience, but 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,” says Lee Naik, chief executive officer and regional president, TransUnion Africa. “Consumers are not facing a new problem, but a deepening of pressures that already exist”

TransUnion notes that affordability pressures have intensified through much of 2026. High unemployment continues to constrain household income growth and weaken financial resilience, contributing to cautious spending behaviour and increased demand for credit.

What the Decision Means for Consumers

A 25-basis point increase is expected to raise monthly repayments on a R1 million home loan by approximately R160 to R170 per month, while repayments on a R2 million 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.

Although relatively modest in isolation, these additional costs arrive at a time when households are already contending with high living expenses and tighter budgets.

TransUnion expects 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.

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.

"South Africans have shown remarkable resilience, but affordability remains fragile. The increase reinforces the need for consumers to proactively manage debt, preserve liquidity and maintain healthy credit profiles," says Naik.

Looking Ahead

TransUnion expects affordability to remain a defining issue for consumers through the remainder of 2026. Elevated fuel and transport costs, weak economic growth, rising unemployment and pressure on household budgets are expected to continue shaping consumer spending and borrowing behaviour.

Statistics South Africa reported that GDP contracted by 0.2% in Q2 2026, while the RMB/BER Business Confidence Index fell to its lowest level since 2024, reflecting continued pressure on economic activity, employment growth and consumer confidence.

The key risk for households is not any single affordability shock, but the cumulative impact of multiple pressures occurring simultaneously, including fuel inflation, constrained income growth, elevated unemployment and increasing reliance on credit to manage day-to-day expenses.

"Whether rates remain unchanged or increase, the reality for many households remains the same: consumers are focused on preserving cash flow, protecting repayment performance and managing essential expenses in a challenging economic environment," says Naik. "Affordability will continue to shape how South Africans spend, save and borrow in the months ahead."
