As the stand-off between the United States and Iran over the Strait of Hormuz intensifies, the global economy is bracing itself for the consequences. Oil prices have surged by 4.7% in a single day, reaching a new high of $79.59 per barrel, as investors grow increasingly anxious about the stability of oil supplies through this critical waterway. Brent crude, the international benchmark, has hit its highest level since May, and the ripple effects are being felt across global stock markets.
The latest escalation came on Sunday evening, when US military strikes against Iran prompted an immediate retaliatory response from Tehran. The US Central Command (Centcom) stated that these strikes were aimed at "continuing to degrade their ability to attack civilian mariners and commercial ships freely transiting the Strait of Hormuz", with US President Donald Trump directing these actions to "hold Iranian forces accountable" for their activities in the region.
The impact has been severe, particularly on Asian stock markets. South Korea's Kospi index plummeted by 8%, while Japan's Nikkei 225 and China's Shanghai Composite also saw declines of 2%. Technology companies, including chipmakers, were among the hardest hit, with shares in South Korean semiconductor giant SK Hynix slumping by 15% and its competitor Samsung Electronics experiencing a 10% drop. This serves as a stark reminder of the interconnectedness of global supply chains and the immediate impact that geopolitical instability can have on key industries.
The Strait of Hormuz, which accounts for approximately one-fifth of the world's oil supply, remains a flashpoint. Data analyst Kpler reported a significant reduction in vessel traffic through the strait on Sunday, with only six vessels crossing – the lowest level in five weeks. While President Trump asserted that the route remains open for commercial traffic, Iran earlier claimed to have closed the strait following a vessel travelling an unapproved route. The Iranian Revolutionary Guards also stated that their navy had stopped two ships on Sunday by disabling their systems, though specific vessel names were not disclosed.
These developments cast further doubt on the fragile interim US-Iranian truce signed last month. Analysts at Goldman Sachs noted that the "recent attacks highlight how uncertain Gulf exports remain and that a serious re-escalation could re-intensify the short-run upside risk to oil prices". The broader economic implications are also being felt, with gold prices falling by 1.5% to $4,060.36 an ounce on Monday, as investors become increasingly cautious about higher oil prices leading central banks to raise interest rates and make non-yielding assets like gold less attractive.
