Iran has threatened the United States with what it calls “economic warfare” and warned of further military action as the six month old conflict enters another period of escalation. Tehran says it has used an advanced missile against U.S. warships, while Iran backed Houthi fighters have attacked several Saudi Arabian cities.
The developments come only days after the United States struck three Iranian oil tankers, while diplomatic efforts to end the conflict remain stalled.
What’s Happening
Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, said on Tuesday that Washington had received a warning through Iran’s new missile capabilities. He threatened to establish a maritime exclusion zone across the Persian Gulf up to the U.S. blockade perimeter.

Iran had already announced plans for a new restricted zone in the Gulf and a new shipping corridor through the Strait of Hormuz. Tehran says vessels entering the restricted area could be placed on an Iranian sanctions list.
Iranian state media also reported that the country had fired the Qassem Basir missile at U.S. vessels near the Strait of Hormuz. The U.S. military, however, said its warships evaded any missile attacks.
Houthi Attacks Add to Regional Risk
The conflict is also spreading beyond direct U.S. and Iranian confrontation.
Iran backed Houthi forces attacked several cities in Saudi Arabia, injuring 73 people, according to a spokesperson for the Saudi led coalition in Yemen.
The attacks underline the possibility of a broader regional conflict involving countries that host U.S. military bases or are connected to the region’s energy infrastructure.
Strait of Hormuz Remains a Key Pressure Point
Iran continues to disrupt shipping through the Strait of Hormuz, one of the world’s most important energy routes.
Before the war, around one fifth of global oil and liquefied natural gas shipments passed through the Strait. Iran’s ability to threaten shipping has therefore given Tehran significant leverage, while disruptions have contributed to higher energy prices.
However, some analysts believe Iran’s leverage over the Strait could be weakening as the United States attempts to maintain shipping flows and imposes increasingly severe sanctions on Tehran.
Iran’s Missile Capabilities
Iran has described the Qassem Basir as an upgraded missile with improved manoeuvrability and the ability to evade missile defence systems. Iranian media has also said its guidance system can operate effectively against electronic warfare.
Despite U.S. attacks that have weakened Iran’s conventional military capabilities and placed additional pressure on its economy, Tehran has retained missile and drone capabilities that can threaten shipping and U.S. interests across the region.
Economic Pressure Is Mounting
Military pressure is being accompanied by an increasingly severe economic squeeze.
Iran’s economy was already struggling under U.S. sanctions, while the blockade of its oil exports has further restricted its revenues. Iranian officials acknowledge problems including inflation, currency fluctuations, unemployment and market instability.
Tehran has rejected the idea that economic pressure will force it to change its political course. Instead, Iranian officials say the government intends to pursue economic reforms while continuing to resist U.S. demands.
Why It Matters
The latest escalation creates risks on several fronts.
For the global energy market, continued disruption around Hormuz could push oil and gas prices higher. For the United States, higher fuel prices could become a political problem ahead of November’s congressional elections.
For Iran, the Strait remains one of its most important strategic tools, but its economic position is becoming increasingly difficult as sanctions and the oil blockade take effect.
The involvement of the Houthis also raises the possibility that the conflict could become a wider regional confrontation rather than remaining limited to the United States and Iran.
Key Stakeholders
Iran: Seeking to maintain military deterrence while using the Strait of Hormuz as economic and strategic leverage.
United States: Attempting to enforce its blockade, protect shipping and pressure Tehran to abandon its nuclear and regional military ambitions.
Houthis: Their attacks demonstrate how Iran aligned groups can expand the conflict beyond the immediate U.S. Iran battlefield.
Saudi Arabia: Increasingly exposed to attacks because of its role in the regional conflict and its close relationship with Washington.
Global energy markets: Vulnerable to any sustained disruption of oil and LNG flows through Hormuz.
What’s Next
The immediate concern is whether Iran follows through on its planned maritime exclusion zone and whether further attacks target shipping or U.S. military positions.
The proposed shipping restrictions could further reduce traffic through Hormuz, while additional Houthi attacks could widen the geographic scope of the conflict.
At the same time, the stalled diplomatic process leaves limited room for de escalation. Tehran continues to demand sanctions relief, while Washington has yet to achieve the objectives it set when it launched Operation Epic Fury.
Analysis
The latest developments show Iran attempting to fight the United States on two interconnected fronts: military pressure and economic disruption.
Tehran’s missile threats are intended to preserve its ability to deter U.S. forces, while control over shipping through Hormuz gives it another means of imposing costs without relying solely on direct military confrontation.
But Iran also faces a difficult calculation. Its ability to disrupt the Strait gives it leverage, yet prolonged disruption can hurt Iran itself by damaging trade and worsening economic pressure.
The central question now is whether the confrontation produces enough pressure on either side to return to negotiations, or whether missile attacks, shipping restrictions and regional strikes push the conflict into a broader war.
