Higher Borrowing Costs Hit South African Households as Central Bank Raises Rates

South Africans managing household budgets will feel the direct impact of a new interest rate increase announced Wednesday, as the South African Reserve Bank lifted its benchmark rate by 25 basis points to 7.25%. The unanimous decision pushes the prime lending rate to 10.75%, making mortgages, car loans, and credit card debt more expensive for families and businesses already contending with rising living costs.

The rate rise arrives as the national economy contracted by 0.2% in the second quarter, a sign of weakness that forced the central bank’s hand despite earlier hopes for stability. SARB Governor Lesetja Kganyago acknowledged the mounting pressures in a public address, stating that “global shocks are clearly hurting our economy.” Disruptions from conflicts in the Middle East and between Russia and Ukraine have snarled supply chains and driven energy costs upward, effects that ripple through South Africa’s economy as an oil-importing nation dependent on global trade.

The central bank’s own forecasts underscore the fragility ahead. SARB projects annual growth of 1.2% for the year but has flagged that “growth risks are skewed to the downside.” In one scenario modeled by the institution, interest rates could climb by an additional 100 basis points over the next year, a prospect that would further strain household budgets and business investment.

Inflation remains a persistent concern for ordinary South Africans managing daily expenses. The Consumer Price Index rose to 4.4% in September from 4.3% in July, and SARB expects headline inflation to exceed 5% later this year and into early 2027. Food prices, which had been easing, reversed course in September: seafood jumped 7.5% compared to 6.6% the previous month, and dairy products climbed to 2.1% from 1.9%. These increases land directly on what families spend at the grocery store.

Meanwhile, independent economists are cautious about how quickly relief will arrive. Jee-A van der Linde, Senior Economist at Oxford Economics Africa, warned that inflation pressures may prove more stubborn than the central bank hopes. “If you look at the current conditions, there is a risk of elevated inflation for next year… it may not come down as swiftly as the SARB would like,” van der Linde told Forbes Africa. Core inflation continues to drift upward, suggesting that price pressures may persist even as headline figures fluctuate.

The immediate outlook for economic activity remains dim. Van der Linde expects the third quarter to show stagnant growth, with the economy remaining flat despite a temporary reprieve from lower fuel prices mid-year. Any recovery in the final quarter would depend on favorable conditions that remain uncertain, including sharp drops in fuel costs and a shift in global commodity prices.

For households, the timing compounds existing pressures. Van der Linde noted that the hike “will weigh on consumer sentiment and eventually household growth heading into the festive season and could constrain growth heading into 2027.” Higher borrowing costs reduce discretionary spending at a time when many families are already stretched. Fixed investment growth is expected to remain weak regardless, suggesting businesses are also pulling back on expansion plans.

The central bank projects around 2% growth over the coming years if global conditions stabilize, and expects inflation to return to its target band near 3% by the end of 2027. Whether that medium-term recovery materializes, or whether a further 100 basis points in rate rises intervenes first, will determine how long the squeeze on ordinary South Africans continues.
