The United States is sharply escalating economic pressure on Iran, with Washington threatening a tighter blockade and what Treasury Secretary Scott Bessent calls the “toughest sanctions in history.”
The measures are aimed at cutting off Iran’s remaining economic lifelines, while President Donald Trump has warned countries and companies supporting Tehran that they could face severe economic consequences.
Washington is putting particular pressure on Iran’s oil exports and financial networks, while also urging major trading partners to stop providing Tehran with revenue.
China is now at the centre of the dispute. Beijing buys the majority of Iran’s exported oil, but Chinese officials have rejected coercive sanctions and argued that diplomacy—not economic pressure—is needed to resolve the crisis.
The standoff comes as tensions over the Strait of Hormuz continue to disrupt shipping and put pressure on global energy markets. Tanker traffic through the strategic waterway has fallen sharply amid the confrontation.
Washington says tougher economic measures could force Tehran back toward an agreement, while Iran continues to reject U.S. pressure.
With diplomatic efforts stalled and the economic campaign widening, the confrontation is increasingly becoming a test of whether sanctions can achieve what military pressure has not.
