Inflation Risks Re-emerge as a Key Consideration for the Commercial Property Sector

The resurgence of geopolitical tensions has rekindled concerns about inflation at a time when many economies had begun to anticipate a more benign interest-rate environment. For South Africa, the principal risk lies not only in the direct impact of higher energy and transport costs, but also in the effect that elevated inflation expectations may have on monetary policy and long-term borrowing costs. Moreover, rising inflationary expectations erode business confidence.

The graph above illustrates the close relationship between the dividend yield in the listed property sector and the South African long bond yield. Listed property securities compete directly with government bonds for investor capital, making movements in bond yields a critical determinant of sector valuations. As bond yields rise, investors generally require higher property yields, placing pressure on capital values. Conversely, a stable inflation outlook and lower bond yields provide a more supportive backdrop for property markets. In this regard, the trajectory of inflation expectations may prove as important to the sector's outlook as the inflation rate itself.

The South African Reserve Bank's latest Monetary Policy Committee (MPC) statement highlighted potential inflationary concerns. While inflation remains broadly contained, the Bank cautioned that an escalation of current conflicts could push consumer prices materially higher. In its adverse scenario, inflation could rise by up to 1 percentage point above the baseline forecast. Against this backdrop, the recent 25-basis-point increase in the repo rate underscores the Bank's determination to preserve its inflation-fighting credibility and prevent expectations from becoming unanchored.

For the property sector, inflationary pressures are most visible in operating costs. Although property owners have demonstrated resilience in managing expenses, administered prices continue to rise at rates well above headline inflation. Electricity tariffs, municipal charges, water costs, rates and taxes have become increasingly significant drivers of expenditure, placing pressure on both landlords and tenants. In the retail sector, a higher inflation rate places pressure on household balance sheets and consumption expenditure.

In 2025, increases in several administered prices exceeded 10%, continuing to pressure net operating costs across the property sector. While some of these increases can be recovered through lease structures, persistently elevated cost escalation remains a challenge for property owners and managers seeking to protect income streams and maintain asset performance.

Recent data from Statistics South Africa suggests that these pressures remain elevated. The annual increase in the Producer Price Index (PPI) for electricity and water measured 12.5% in April 2026, moderating from 17.9% in March. Yet the index rose by 1.5% month-on-month, indicating that utility inflation remains firmly embedded in the economy's cost structure.

The broader concern for property investors lies in the relationship between inflation expectations and long-term interest rates. Expectations of higher inflation typically translate into higher government bond yields as investors demand greater compensation for future inflation risk. This raises the cost of capital and places downward pressure on asset valuations.
