Crude oil prices jumped approximately 9% on Monday as President Donald Trump announced the reimposition of a blockade on Iranian shipping through the Strait of Hormuz.

The decision, reported by Polish business media Puls Biznesu, triggered an immediate and nervous reaction across global markets, with Wall Street’s major indices closing lower amid a broad risk-off selloff.

The sharp repricing in energy markets reflects renewed fears of physical supply disruption in the Middle East.

The Strait of Hormuz remains a critical chokepoint for global oil flows, and any restriction on Iranian navigation directly threatens the stability of global energy supplies.

This development marks a significant escalation from previous diplomatic posturing, moving the conflict into the realm of tangible logistical risk.

Equity markets struggled to find footing as the geopolitical premium surged.
