The resumption of military clashes between the United States and Iran triggered a sharp rise in oil prices, negatively affecting global stocks and pushing investors back into risk-averse mode. These geopolitical tensions, which arose on Wednesday, are worrying global financial markets.
Commodity Market Reaction
The conflict premium quickly recovered after the US struck dozens of Iranian targets in response to attacks on vessels in the Strait of Hormuz. The price of Brent crude increased from $71 to over $76 per barrel in just two trading days as concerns about global energy supply resurfaced.
This new wave of escalation reversed the downward trend in oil prices that had been observed for several weeks amid optimism regarding a peace agreement announced only three weeks ago. Investors began reducing their exposure to risk assets.
Stock Market Dynamics
The change in investor sentiment was reflected on the Johannesburg Stock Exchange (JSE): the All Share index fell by 0.8%, closing at 110,325.50. Shares in banks, telecommunications companies, and gold and platinum mining enterprises came under pressure. Among the few positive notes were technology giants Naspers and Prosus, which rose by 5.2% and 4.2%, respectively.
Global stock markets also showed growing caution. In the United States, the S&P 500 index fell by 0.4%, Nasdaq lost 1.2%, and the Dow Jones Industrial Average decreased by 0.2%. The decline was led by semiconductor companies: Intel dropped by 9.7%, AMD by 6.5%, and Micron Technology by 4.7%, amid persistent concerns about AI valuations and overall geopolitical uncertainty.
Asian markets showed a mixed picture on Wednesday morning: Japan's Nikkei 225 fell by 0.7%, and South Korea's Kospi dropped by 1%, while Hong Kong's Hang Seng rose by 2%.
Energy and Currency Exchange Rates
Energy companies benefited from the sharp rise in oil prices. In the US, shares of Devon Energy (+5.1%), Diamondback Energy (+3.9%), and Chevron (+3.5%) rose. Anchor Capital noted that Brent Crude rose by 3% on Tuesday, and then another 2.6% at the start of trading on Wednesday.
Gold initially fell by 1.6% while investors awaited the publication of the US Federal Open Market Committee minutes, but later partially recovered its losses due to the return of demand for safe-haven assets. During Tuesday's trading, the South African rand weakened against the US dollar amid heightened geopolitical tension, although the local currency showed a moderate recovery at the start of Wednesday's trading.
Financial and Economic News
Bond markets also reflected cautious sentiment: the yield on South Africa's 10-year government bonds slightly increased to 8.34%. In other regions, Germany reported a positive economic surprise, as industrial production grew by 0.9% in May compared to the previous month, marking the second consecutive month of growth. In the UK, the Lloyds housing price index rose by 0.2% in June, the first monthly increase in four months.
Corporate events also drew attention. One of the most significant announcements for South Africa was the agreement by Abu Dhabi National Oil Company to acquire Shell's fuel supply business in South Africa, expanding the presence of the UAE state-owned energy company in Africa's largest economy. Anchor Capital characterized this deal as 'part of a broader drive by Gulf states to enter African energy markets.'
In Europe, bank regulators intensified oversight of artificial intelligence, warning that advanced AI models could create systemic risks for the financial sector. Banks were reportedly given four months to strengthen defenses against AI-driven cyber threats. Meanwhile, Airbus announced a joint venture with MTU Aero Engines to develop hydrogen engine power unit technology for aircraft, a step towards decarbonizing the aviation industry.
Investors are now expected to closely monitor developments in the Middle East, as oil prices, inflation expectations, and central bank policies are likely to remain highly sensitive to further geopolitical changes.
