Consumer Inflation

August 2025

In August 2025, the Consumer Price Index (CPI) experienced a modest increase to 3.3%, down slightly from 3.5% in July. This was marginally below analysts’ forecast of 3.6% for the month.

The rise was predominantly attributed to:

  • Housing and Utilities: Up by 4.3%, contributing 1.0 percentage point.
  • Food and Non-Alcoholic Beverages: Increased by 5.2%, adding 0.9 percentage points.

On an annual basis, inflation for goods edged up slightly to 3.1%, compared to 3.2% in July, while services inflation remained steady at 3.6% for August 2025. Although the pace of price increases has slowed, inflation continues to erode household purchasing power across South Africa, albeit at a reduced rate. As a result, many families are increasingly relying on short-term credit to sustain their lifestyles and consumption patterns. This dependence heightens their vulnerability to fluctuations in interest rates and currency values, which can influence domestic prices.

During its July meeting, the Monetary Policy Committee (MPC) decided to lower the interest rates. The outcome of the September interest rate decision, which will be announced later this week following the latest inflation data, is highly anticipated. It is expected that the South African Reserve Bank (SARB) may opt to keep interest rates unchanged for the month, despite the slight decline in consumer inflation from July to August. This approach could reflect the Bank’s cautious stance on inflation and price stability amid ongoing economic uncertainties, such as the 30% US trade tariffs impacting South African exports. These uncertainties could also influence the Rand’s exchange rate against the US dollar, as more data from August and September becomes available. The SARB may therefore adopt a “wait-and-see” approach to supporting the Rand and maintaining domestic price stability in the short to medium term.

The interest rate reductions implemented in late 2024 and early 2025, along with the July rate cut, are expected to stimulate demand by increasing household disposable income after interest payments, potentially fostering overall economic growth. This is supported by the latest economic growth figures of 0.8% released by StatsSA.

Despite this positive outlook and the slightly above-market expectation growth for the second quarter of 2025, the Reserve Bank remains cautious due to ongoing global uncertainties. Concerns such as inflation, the US-China tariff dispute, and potential additional tariffs on BRICS nations could impact price stability. Future interest rate decisions are likely to be influenced by factors such as moderate inflation, sluggish economic growth, improvements in electricity supply, and positive market sentiment.

Ultimately, maintaining price stability and safeguarding the domestic value of the Rand remain priorities as South Africa navigates the second half of 2025.

Unpacking the Undervaluation and Economic Implications
As of October 2025, the South African Rand is trading at R17.15 against the US Dollar, a significant figure in the context of an estimated average exchange rate of R18.20 from January to September 2025. Market analyses leveraging the Purchase Power Parity (PPP) exchange rate – calculated using inflation differentials between South Africa and the US from 2020 to 2025 – indicate that the Rand remains undervalued. This disparity suggests an alignment closer to R14.30 in a conservative estimation and potentially as low as R11.30, revealing a risk premium embedded in the current forex dynamics.
Bold and Radical Shift in Policies are required.
South Africa’s economy recorded modest growth of just 0.8% during the second quarter of 2025, continuing a pattern of sluggish expansion that has persisted over the past decade. With the economy still struggling to break free from its constraints, serious reforms and strategic policy adjustments are essential if South Africa is to achieve sustainable growth rates significantly higher than the current 0.8% average.
