Iran Threatens US With New Missiles as Gulf ‘Exclusion Zone’ Plan Advances

Core Summary

Reuters reported on September 8 that, alongside its plan to establish a new “exclusion zone” in the Persian Gulf, Iran issued a fresh missile threat against the United States. Senior Iranian military officials warned through state media that US military bases in the Middle East, if used for operations against Iran, would become targets for Iranian new-generation missiles. This marks the second major Iranian deterrence statement against the US within less than 24 hours. The US-Iran maritime standoff escalated further, and international oil prices continued to climb in response.

Event Details

Missile Threat Details: A senior Iranian Revolutionary Guard Corps (IRGC) commander issued a statement on September 8 through state television, warning that US military deployments in the Middle East “have become legitimate targets for Iranian missiles.” The statement specifically named key facilities, including Al Udeid Air Base in Qatar, the US Fifth Fleet headquarters in Bahrain, and Camp Arifjan in Kuwait. The Secretary of Iran’s Supreme National Security Council posted on social media that “new missiles have locked onto all enemy targets and will strike back immediately upon any trigger.”

New Gulf “Exclusion Zone”: Beyond the missile threat, Iran’s Foreign Ministry confirmed that a new “exclusion zone” in the Persian Gulf will be officially declared within 48 hours. The new zone will cover approximately 3,000 square kilometers and include parts of international shipping lanes. The Iranian Navy will step up patrols in this area and warn or expel unauthorized foreign warships. Iran’s permanent mission to the United Nations has sent a letter to the UN Secretary-General setting out Iran’s position.

Market Reaction: After the announcement, international benchmark Brent crude prices rose another 2.1% intraday, with US West Texas Intermediate climbing in tandem. During the Asian morning trading session, the global shipping index dipped slightly, while war-risk insurance premiums for Persian Gulf voyages rose by another 8%. Major global shipping companies updated their internal safety advisories within hours.

US Response: The White House National Security Council issued a statement expressing “grave concern” over Iran’s missile threat, emphasizing that “any threat against US forces will be met with a resolute response.” The Pentagon announced adjustments to the posture of certain Middle East deployments, but stressed that US forces will not withdraw from the region. The State Department has also briefed Gulf allies on the situation through diplomatic channels.

Panoramic Analysis

Iran’s successive release of “expanded control” and “missile threat” signals within less than 24 hours marks the entry of US-Iran competition into a new high-risk phase. The strategic intent and implications of these statements warrant deeper analysis.

First, Iran’s “offense-as-defense” strategy has reached a new intensity. Over the past few years, in response to continued US pressure, Iran has gradually built an “asymmetric counter” system. Previously, however, Iran’s countermeasures remained largely in the “grey zone” — tanker seizures, announcements of maritime restricted zones, and low-intensity maritime confrontations. By directly targeting specific US military facilities in the Middle East, Iran has now shifted its counter-measures from the “grey zone” to “explicit deterrence.” This escalation reflects both Iran’s confidence in its improved missile capabilities and the urgency felt by Iran’s decision-makers in the current geopolitical environment. Against the backdrop of continued US force reinforcements to the Middle East and a new round of sanctions in the making, Iran’s choice to confront head-on through “missile naming” is intended to create a “red-line effect” that forces the US to act cautiously.

Second, a “missile + maritime control” dual-track deterrence has formed a new structure. By simultaneously launching the missile threat and the new Gulf “exclusion zone,” Iran has shown a substantial increase in the systematization of its deterrence strategy. The maritime “exclusion zone” targets international shipping and US naval forces, while missile deterrence targets US land and air forces — together forming a “three-dimensional deterrence” network. This dual-track strategy not only complicates the US response, but also creates additional leverage for Iran in negotiations. If the US chooses a tough response, Iran can selectively escalate on either the maritime or missile front; if the US chooses restraint, Iran can consolidate its presence in the Gulf.

Third, global energy markets have entered an era of “geopolitical risk premium”. Iran’s tough statements on two consecutive days have pushed international oil prices past the key $92-per-barrel mark, with European natural gas prices rising more than 4%. The market’s “geopolitical risk premium” on the Strait of Hormuz is being pushed higher, and this premium will gradually be reflected in global energy prices, transport costs, insurance premiums, and ultimately consumer prices. For oil-importing countries, this means renewed imported inflationary pressure; for oil producers, it means higher short-term fiscal revenues. Over the medium and long term, the structural fragility of global energy markets is being amplified by Iran’s repeated statements.

Fourth, “red-line testing” risk in great power competition has risen. Iran’s listing of specific US military facilities as targets is an extremely rare “red-line test” in international relations. Such statements are both a response to the US’s maximum pressure and a probe of the international community’s tolerance. If similar statements become the norm, the concept of “red lines” in international relations will be diluted, and the risk of misjudgment in great power competition will rise significantly. This also presents a new challenge for multilateral mechanisms such as the UN Security Council and the Gulf Cooperation Council: how to prevent unilateral “red-line” statements from triggering chain reactions, while respecting the legitimate security concerns of all states.

Multiple Perspectives

IRGC Position: Senior IRGC commanders emphasized that the range and precision of Iran’s new missiles cover all US military facilities in the Middle East, warning the US not to “test Iran’s resolve.” The IRGC Navy commander simultaneously announced that large-scale live-fire exercises will be held in the new Persian Gulf “exclusion zone.”

US Government Position: The White House issued a statement expressing “grave concern” over the missile threat, emphasizing that “US forces have the ability to respond to any threat.” The Pentagon said it is coordinating with Gulf allies on strengthened defensive deployments and retains the option of “preemptive action.”

Gulf States’ Position: Saudi Arabia, the UAE, Qatar and other Gulf states have kept a low profile on Iran’s statements but have launched urgent internal consultations. Gulf states are concerned that escalation could affect their civilian infrastructure and shipping safety, with some countries already asking their citizens to avoid traveling to Iran.

European Union Position: The EU High Representative for Foreign Affairs issued a statement calling on all parties to “exercise maximum restraint,” stressing that “any unilateral escalation will bring unpredictable consequences.” The EU also said it is maintaining close communication with the US to avoid misjudgments.

International Shipping Industry: Major global shipping companies updated their internal advisories within hours, warning all Persian Gulf vessels to “prepare for contingencies.” The insurance industry continues to raise war-risk premiums for Persian Gulf voyages, reflecting the market’s ongoing repricing of risk.
