US opens economic war front. What are Iran's options to escalate further?

The United States has opened a new front in its confrontation with Iran. Washington has sharply escalated economic pressure on Tehran as the war approaches its six-month mark. US Treasury Secretary Scott Bessent described the campaign as an "economic D-Day". The US is seeking to cut Iran off from the dollar-based financial system and sever the revenue channels that have helped sustain its economy."We are launching an economic onslaught against Iran’s financial connections around the globe. Our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone," Bessent said.The pressure puts Tehran in a difficult position. Iran can absorb the economic pain or raise the cost of the conflict for the US and its allies. But any major escalation could widen the war and further disrupt global energy markets.CAN IRAN HALT OIL SHIPMENTS?One of Tehran's most powerful options is to further restrict oil exports from the Persian Gulf and Strait of Hormuz. Mohsen Rezaei, a former Revolutionary Guards chief and secretary of Iran's Supreme National Security Council, has already warned that Tehran could take that step. "If the economic war continues, not a single drop of oil will be exported, neither through the Strait of Hormuz nor from anywhere in the Persian Gulf," he said.Iranian attacks and threats against shipping have already drastically reduced traffic through Hormuz, a waterway that carried about a fifth of global energy supplies before the conflict. Further attacks on tankers could push crude prices higher and increase pressure on governments dependent on imported energy. Iran on Sunday also blacklisted 45 tankers that it said had violated its rules for crossing the strait.GULF ENERGY INFRASTRUCTURE REMAINS VULNERABLETehran could also widen its attacks beyond shipping and target oil and gas infrastructure in Gulf states aligned with Washington. Iran has already targeted Gulf countries and Jordan during the conflict, mainly focusing on US military facilities but also striking energy-related sites.More attacks on oil and gas production facilities could have a far greater impact on global markets than isolated shipping incidents. Damage to power stations or desalination plants could also put additional pressure on Gulf states, particularly in a region heavily dependent on desalinated water.Such attacks would carry a significant risk of triggering a greater military response from the US and its Gulf allies.COULD IRAN TARGET THE WEST?Another option is to expand Iran-linked cyber operations and covert activity in Western countries.Britain said on Monday that Iran-linked hackers had disrupted a small electricity station. US officials have also blamed Tehran for suspected cyberattacks targeting water facilities in Minnesota, although Iran has not commented on those allegations.Western security agencies have additionally accused Iran of using local recruits to conduct attacks or assassination attempts in Western countries. Tehran has denied those allegations.Cyberattacks offer Iran a way to impose costs without immediately committing conventional military forces, but a major attack on critical infrastructure could prompt a much stronger response from Western governments.RED SEA OFFENSIVE COULD ADD PRESSUREIran could also rely more heavily on its regional allies, including Yemen's Houthis, to disrupt shipping through the Red Sea and Bab el-Mandeb Strait. Houthi attacks have already forced some vessels to avoid the route, with Chinese shipping companies among those rerouting away from Bab el-Mandeb, according to news agency Reuters.Further attacks on commercial vessels could increase insurance and shipping costs while putting additional upward pressure on oil prices. An attack on a vessel near Saudi Arabia’s main Red Sea oil terminal at Yanbu on Monday, or another strike near the Suez Canal, could intensify concerns in global energy markets.WHAT IS IRAN'S NEXT MOVE?In response to new US sanctions, Iranian Parliament Speaker Mohammad Baqer Qalibaf has dismissed Washington's threats to punish countries that continue trading with Iran, saying Tehran's trade partners have no intention of complying with US pressure.In a post on X on Monday, Qalibaf said countries maintaining commercial ties with Iran had conveyed that they would disregard Washington's warnings. He said those messages had been communicated both publicly and directly to Iranian officials. The Iran's negotiator also challenged Washington's ability to impose further economic restrictions, arguing that the US economy itself was facing pressure from the prolonged conflict with Iran."The Americans know that no one believes their big talk; the United States is not in a position economically to further restrict its relations with other countries," he said.However, each escalation comes with a trade-off. Disrupting energy supplies could undermine Washington's economic pressure campaign, but it could also deepen Iran's isolation and increase the chance of a dangerous wider military confrontation.- EndsPublished On: Aug 25, 2026 02:02 IST
