A central bank-commissioned quarterly survey found that South African inflation expectations stabilised in the third quarter after a sharp increase in the prior period linked to an oil price shock. Forecasters left the near-term projection for this year unchanged, trimmed expectations for 2027 and 2028, and highlighted the lagged transmission of interest-rate moves.

Key Points

  • Quarterly central bank-commissioned survey found inflation expectations stabilised in Q3 after a sharp rise in Q2 tied to an oil price shock from the Iran war - impacts macroeconomic policy setting and market expectations.
  • Average forecast for headline consumer inflation this year remains at 4.4%, unchanged from the prior quarter, while projections for 2027 and 2028 were trimmed to 4.0% and 3.8%, respectively - relevant for interest-rate decision-making.
  • Inflation measured 4.3% year on year in July; the central bank targets 3% with a +/-1 percentage point tolerance band, and policymakers face an upcoming rate decision on September 23 that markets will watch.

JOHANNESBURG, Sept 16 - South African inflation expectations levelled off in the third quarter, according to a quarterly survey commissioned by the central bank, after a steep uptick in the prior quarter attributed to an oil price shock tied to the Iran war.

The survey, which is used by the central bank to inform its view on appropriate interest-rate settings, reported an average forecast from a mix of analysts, business representatives and trade union officials. That average forecast for headline consumer inflation this year was 4.4%, unchanged from the second-quarter survey.

Looking further ahead, the panel trimmed its outlook for the following two years. The mean projection for 2027 fell to 4.0% from 4.2%, while the average for 2028 declined to 3.8% from 3.9%.

The central bank highlights that changes to its policy rate affect the economy with a lag of about 12 to 24 months - a timing convention cited in the survey that underscores why multi-year expectations matter for policy calculation.

Recent price data show headline inflation at 4.3% year on year in July, the latest month for which statistics were available at the time of the survey.

The bank formally targets inflation at 3% with a tolerance band of plus or minus 1 percentage point either side of that target.

Policy action earlier in the year surprised some market participants when the central bank left its main lending rate unchanged in July, following its first rate increase in three years in May. The next interest-rate announcement is scheduled for September 23, creating an imminent policy milestone market participants will watch closely.

Context and implications

The survey results signal a pause in upwards revision to inflation expectations after the previous quarter's spike linked to elevated oil prices. The unchanged 2026 forecast and modest downward revisions for 2027 and 2028 reflect a measured reassessment of medium-term price pressures while recognising the lag with which policy operates.

Because the central bank uses these survey results to help set policy, the combination of current inflation readings, survey expectations and the policy-transmission lag will shape deliberations ahead of the September 23 announcement.

Risks

  • Oil price volatility - the prior quarter's sharp rise in inflation expectations was linked to an oil price shock associated with the Iran war, creating downside risk for inflation stability and sectors sensitive to energy costs such as transport and manufacturing.
  • Policy timing uncertainty - the central bank notes that interest-rate changes work with a lag of roughly 12 to 24 months, producing uncertainty about when monetary tightening or easing will feed through to the broader economy, affecting interest-rate sensitive sectors like housing and investment.
  • Data lag - the most recent inflation figure cited was for July, indicating a potential limitation in timely price information that could affect near-term policy judgements and market positioning.
