The crisis in the Middle East has entered a critical new phase after United States President Donald Trump ordered the U.S. Navy to block the strategic Strait of Hormuz following the collapse of peace negotiations with Iran.

The U.S. Central Command (CENTCOM) confirmed the measure will take effect সোমবার at 10:00 a.m. Eastern Time and will target vessels entering or leaving Iranian ports.

Diplomatic breakdown in Pakistan

The move follows marathon negotiations held over the weekend in Pakistan, where U.S. Vice President JD Vance and Iranian official Mohammad Bagher Ghalibaf engaged in more than 20 hours of talks without reaching an agreement.

According to officials, key sticking points included Iran’s nuclear program, funding of allied groups, and full access to the Strait. The failure leaves the fragile ceasefire reached on April 7 in doubt and raises the risk of renewed escalation.

Strategic blockade and rising threats

Trump framed the blockade as a pressure tactic against Tehran, accusing it of restricting free navigation and continuing its nuclear ambitions. He also warned of severe retaliation against any hostile action.

Iranian authorities quickly responded, vowing to retaliate against any military vessels in the area, heightening the risk of direct confrontation in one of the world’s most critical maritime corridors.

Immediate impact on global markets

The Strait of Hormuz is a vital chokepoint for global energy supply, with around 20% of the world’s oil passing through it. Markets reacted swiftly: oil prices surged above $100 per barrel, while Brent crude jumped 8%.

The development raises concerns over broader economic fallout, including rising energy costs and renewed inflationary pressures worldwide.

An uncertain path forward

Analysts say deep-rooted differences between Washington and Tehran make a quick resolution unlikely. Control of the Strait, nuclear ambitions, and geopolitical rivalries remain central to the conflict.

As the blockade begins, the situation enters a more volatile stage with potentially far-reaching global consequences.
