Crude oil prices vaulted towards the $100-a-barrel threshold on Wednesday, propelled by a sharp escalation in military exchanges between the United States and Iran that dashed any lingering hopes for a diplomatic breakthrough. Brent, the global benchmark, surged past $97, while West Texas Intermediate (WTI) climbed above $96, as traders rushed to price in heightened geopolitical risk.

The day’s rally was ignited by a series of hostile acts. American airstrikes targeted the Iranian island of Qeshm, a response to what Washington described as earlier provocations. Hours later, Iranian projectiles struck Kuwait’s international airport, killing one person and shattering a fragile ceasefire that had held since 8 April. The attack on Kuwait, a neutral Gulf state, marked a dangerous widening of the conflict. Both governments traded accusations, each blaming the other for collapsing the truce.

Viewed from Washington, some officials reportedly believe the end of the prolonged confrontation may be in sight—a perception starkly at odds with events on the ground. In European trading centres, analysts expressed scepticism, noting that the renewed violence pushes any settlement further away and revives the spectre of a disrupted Strait of Hormuz, through which a fifth of global oil supplies passes. For oil-exporting Latin American nations such as Argentina, the price spike offered a fleeting fiscal windfall, but broader emerging markets braced for renewed inflationary import costs.

The ripple effects were immediate. Wall Street opened lower, with the Dow, S&P 500 and Nasdaq all retreating, as investors weighed the potential for a global inflation shock. After weeks of easing energy costs, the sudden reversal threatened to complicate central-bank policy across major economies. Market volatility indices climbed, and analysts warned that without a credible path back to negotiations, oil could test the psychologically critical $100 mark in the days ahead.
