US-Iran Economic Warfare: Sanctions and Naval Blockades

The United States and Iran are locked in economic conflict three weeks after a ceasefire took effect, as the Trump administration attempts to subdue Tehran through a naval blockade and increased sanctions, according to a report from War on the Rocks.

The U.S. Is squeezing Iran on two fronts: a naval blockade restricting maritime trade and escalating sanctions targeting its oil and banking sectors. This comes after a period of open hostilities and unsuccessful negotiations, the report states.

Prior to the recent conflict, the Iranian government was already facing significant financial challenges. The U.S. Strategy aims to exacerbate these difficulties, building on previous efforts to pressure the Iranian economy.

Esfandyar Batmanghelidj, CEO of the Bourse & Bazaar Foundation, told CNN that Iran had already experienced “the maximum pressure campaign in Trump’s first term and it was forced to cut its oil production by half.” He added that while the blockade will impact Iran’s economic outlook, “the Iranian expectation is that the US itself cannot tolerate that pressure for that long.”

The economic pressure comes as Iran’s currency, the rial, has plummeted to new lows. On Wednesday, April 29, 2026, the rial traded above 1.81 million to the US dollar before partially recovering, according to Al Jazeera. Earlier in the week, it was trading at around 1.54 million, a significant drop from approximately 811,000 per US dollar a year ago.

This latest decline follows a period of relative stability over the past two months, which occurred as U.S. Forces prepared for military action. The economic woes are compounded by unchecked inflation, which is impacting Iranian households.

The U.S. Currently has three aircraft carriers in the region and is deploying additional troops and equipment, as Israel has expressed readiness to resume fighting after a three-week ceasefire, Al Jazeera reported.

The Iranian government, which faced widespread protests over economic conditions earlier this year, is now using the pretext of war to justify the deteriorating economic situation to its population of 92 million, according to War on the Rocks.

The United States has also imposed sanctions on entities and individuals linked to Iran’s proliferation of weapons of mass destruction and related materials, as outlined in a State Department report from January 27, 2026.

Analysts suggest that Tehran may be calculating that the Trump administration, facing domestic backlash over the war and crucial midterm elections, will be unable to sustain the economic pressure for an extended period.
