U.S. President Donald Trump has accused Iran of launching drones at commercial vessels in the Strait of Hormuz, describing the incident as a "foolish violation" of the existing ceasefire agreement.

The claim, made in a social media post, marks a sharp escalation in rhetoric and suggests a direct threat to maritime traffic in the narrow waterway that handles roughly a fifth of global oil consumption.

The allegation comes amid heightened tensions between Washington and Tehran, with Trump previously warning that new military strikes could be on the table if Iran "misbehaves." Earlier reports indicated that the U.S. would "respond" to Iranian actions, including accusations that Iranian forces shot down a U.S. Apache helicopter patrolling the strait.

The combination of drone attacks on shipping and aerial engagements significantly raises the risk profile for commercial operators in the region.

For energy markets, the Strait of Hormuz remains the critical bottleneck for Middle Eastern oil exports.

Any disruption to tanker flows through the corridor typically triggers immediate volatility in Brent crude prices and freight rates.
