South Africa GDP Shrinks 0.2% in Q2 as Iran War Ripples Through Economy

South Africa's economic expansion has come to a halt. Official data released on Tuesday showed gross domestic product (GDP) contracted by 0.2% in the second quarter of 2026 on a seasonally adjusted quarter-on-quarter basis, ending a run of six consecutive quarters of growth.

The reading was slightly worse than the 0.1% decline that economists had anticipated. The data from Statistics South Africa marks the first full quarter of activity to reflect the economic fallout from the war involving the United States and Israel against Iran.

While the conflict began in late February, its impact took time to materialise. Analysts had pointed out that domestic fuel price increases, a key transmission channel of the war's economic shock, would only begin to affect broader activity with a lag. Those ripple effects are now visible in the latest figures.

On an annual basis, GDP grew 0.9% in the April-June period, also falling short of the 1.2% growth that economists had forecast. In a separate revision, first-quarter growth was trimmed to 0.4% from the previously reported 0.5%.

Economists generally regard the quarter-on-quarter measure as the more reliable gauge of the economy's underlying momentum, making the contraction a clear signal that the war's economic costs are now weighing heavily on South African output.
