South African households entered the second half of 2026 with stronger financial foundations than projected, though economist John Loos warns that the stability observed in the first half may erode quickly as rising oil prices, inflation, and higher interest rates create strain. The escalation of the Iran conflict has already sent fuel costs upward, pushed consumer inflation past 5%, and prompted the South African Reserve Bank (SARB) to raise rates in May. The economic impact of these adjustments has yet to fully spread through the financial system.
Loos’s latest Household Sector Economy report indicates that while second-quarter data appear steady, the financial system operates with delays. The chain reaction—higher oil prices leading to increased fuel costs, then inflation, followed by rate hikes, mounting debt pressure, and mortgage stress—has not yet reached its peak. The focus now shifts from whether these pressures will materialize to how swiftly they will take hold.
Consumer spending remains firm; but the outlook dims
Real household consumption expanded by 0.4% in the second quarter despite a 0.2% contraction in real GDP, and annual spending growth reached 2.9%, up from 2.5% in the first quarter. This resilience defied expectations given the Iran conflict’s effect on fuel prices, inflation, and the SARB’s May rate increase. The improvement stemmed from stronger disposable income, with nominal household income growth jumping from 4.6% to 7.8% year-over-year, outpacing inflation and lifting real disposable income growth to 2.97%.
Loos links the income increase partly to investment returns, noting that wage growth weakened alongside sluggish employment figures. Currently, households are spending more while saving less, as the net savings rate worsened from -1.3% to -1.6% of disposable income. This trend signals risk: consumers with limited financial cushions can absorb a single cost increase, but multiple simultaneous rises, higher bond repayments, electricity bills, fuel prices, and food inflation, will strain affordability.
A temporary respite before tighter conditions
Debt indicators improved in the second quarter despite expectations of deterioration. The household debt-to-disposable income ratio fell to 61.3%, its lowest level since 2019. Even the debt-service ratio, interest payments as a percentage of disposable income, dropped slightly to 9.4%, despite the 25-basis-point rate hike in late May. These figures suggest households are better positioned than a year ago, though Loos advises caution, as the improvement may prove temporary.
The second-quarter data reflect conditions before the full effects of the Iran conflict and the SARB’s second rate hike in September took hold. Oil prices remain high due to ongoing tensions, and the SARB’s Leading Business Cycle Indicator has declined since July. Slower growth could weaken wage and employment gains, while the delayed impact of rate hikes will further tighten financial conditions. Loos anticipates another fuel-price shock in October, with petrol potentially climbing by over R3 per liter and diesel following a similar trajectory. This would increase transport, food production, and logistics costs, pushing inflation back toward 5%, or possibly higher.
Key vulnerabilities ahead
Rising fuel costs will ripple through household budgets, affecting transport, food production, and distribution. As petrol and diesel prices increase, families will allocate larger portions of their disposable income to commuting and groceries, reducing funds available for other expenses. Simultaneously, the central bank’s recent policy adjustments add further strain by raising borrowing costs across credit products, including home loans and credit cards. Higher interest obligations will erode the modest gains in debt-service capacity observed earlier this year.
Consequences for the housing sector
Mortgage lenders have already reduced new loan approvals as credit costs rise, a standard response to tighter monetary conditions. This slowdown signals cooling demand for residential financing. Loos expects mortgage approvals to slow and warns rising debt-service costs could produce a moderate increase in home-loan arrears.
