US Escalates Pressure on Iran's Banks and Air Links as War Drags On

The United States is broadening its pressure campaign against Iran, targeting the country's banking channels and aviation links as the war continues, The Wall Street Journal reported.

The measures target the financial pipelines and flight connections that keep Iranian trade moving. Cutting off banks and carriers is a familiar lever in Washington's approach, because it complicates payments, insurance and the movement of goods without directly widening the military conflict. Sanctions also aim to make it harder for Tehran to earn foreign currency and obtain spare parts.

Such pressure rarely works instantly. Sanctions and transport restrictions tend to raise transaction costs and push activity through intermediaries, while enforcement depends heavily on cooperation from allies and private firms. Compliance costs and reputational risk can deter counterparties even where rules are not airtight. Iran has historically sought workarounds, including informal payment networks and alternative carriers.

The practical effect will hinge on how thoroughly the restrictions are enforced and whether partners align with them. For markets, the focus is on whether the campaign disrupts oil flows or regional shipping, and on how Tehran responds. The conflict's trajectory remains the biggest variable.
