The Johannesburg Stock Exchange reached a record level in February 2026 when the FTSE/JSE All Share Index closed at 128,455 points. Soon after, geopolitical tensions pushed global energy markets sharply higher. The JSE correction Iran war oil price dynamic then began to influence investor behaviour and capital allocation.
By 13 March, the benchmark index traded near 114,924 points. The decline exceeded 10% from the February peak. That threshold marks a technical market correction. The market therefore erased more than R2 trillion in capitalisation in only a few sessions.
Market repricing across South African equities
The sell-off has concentrated in consumer and industrial sectors. Investors expect higher fuel costs to weaken household spending and company margins. Retail counters therefore experienced notable declines during the early stages of the correction.
The rand also weakened toward 16.17 against the dollar. Currency depreciation increases the cost of imported energy. That movement reinforces the JSE correction Iran war oil price shock because oil is priced globally in US dollars.
According to the South African Reserve Bank, imported inflation remains a persistent pressure on the domestic price outlook. Energy costs often transmit rapidly across transport and production chains.
Oil surge complicates interest rate expectations
Energy markets triggered the correction. Brent crude traded above $100 per barrel during early March, according to data from the US Energy Information Administration. Prices rose quickly as supply risks increased across Middle Eastern shipping routes.
The oil surge now complicates the policy outlook in South Africa. The JSE correction Iran war oil price dynamic has forced analysts to reconsider the expected interest-rate path.
Earlier in 2026, economists expected the South African Reserve Bank to cut interest rates later in the year. However, rising fuel prices could lift inflation through transport, food and manufacturing costs. Policymakers may therefore delay monetary easing if energy prices remain elevated.
Gold stocks provide partial support
Resource shares have offered some resilience during the equity decline. Investors often shift toward precious metals during geopolitical uncertainty. Gold producers listed on the JSE therefore recorded gains while the broader market retreated.
Even so, commodity strength has not offset the broader equity losses. The JSE correction Iran war oil price shock continues to shape market sentiment across sectors.
Investors now monitor energy markets closely while watching global developments in the Gulf region and trading partners across Asia. Oil prices, inflation expectations and monetary policy signals will likely remain the main drivers of South African equity performance in the coming months.
