United States Treasury Secretary Scott Bessent announced the launch of an economic financial offensive targeting Iran to sever Tehran commercial lifelines. The new measures took effect on Monday morning, incorporating aggressive secondary sanctions against international entities, shipping networks, and trade partners conducting business with Iran. This escalation follows months of regional conflict and major disruptions across Middle Eastern shipping corridors. In response, Iranian officials issued strict warnings, stating that Tehran would halt all oil exports through the Persian Gulf if the economic measures proceed. Global energy markets experienced sharp price volatility amid growing concerns over potential crude oil supply constraints. Treasury officials confirmed that an official press conference in Washington will outline precise enforcement mechanisms and affected target entities. The administration stated that the objective is maximum economic pressure to force a resolution following months of regional instability and stalled diplomatic negotiations across the region starting from early morning today.
