Iran Vows to Expand Control of Strait of Hormuz as Oil and Gas Prices Surge
Core Summary
The Iranian government declared on September 7 that it would “expand control of the Strait of Hormuz,” the latest escalation in Iran’s maritime power play in the Persian Gulf. Within an hour of the announcement, international crude oil prices jumped more than 3% intraday, with natural gas prices climbing in tandem. Major global shipping companies rushed to assess route safety, and military tensions in the Gulf region escalated further. This follows Iran’s earlier announcement of a new restricted zone in the Persian Gulf, marking another extension of Iran’s maritime “grey zone” strategy.
Event Details
Latest Statement: Senior Iranian Foreign Ministry officials issued a statement through official media on September 7, declaring that Iran would “expand control of the Strait of Hormuz.” The statement did not specify concrete measures for the “expanded control,” but the language was tough, emphasizing that Iran “has the right to exercise necessary supervision over international shipping lanes.” Multiple media analyses suggest this could include expanding naval patrol ranges, strengthening vessel inspection regimes, and expelling certain foreign warships.
Oil and Gas Market Reaction: Within an hour of the announcement, international benchmark Brent crude prices jumped more than 3%, briefly breaking the $92-per-barrel mark intraday. U.S. West Texas Intermediate crude rose 3.5% in tandem. European natural gas futures rose more than 4%, and Asian LNG spot prices also saw significant gains. Energy analysts noted that the Strait of Hormuz carries approximately 30% of global seaborne oil trade and 20% of LNG transportation, so any “control escalation” would directly push up global energy costs.
Shipping Industry Emergency Response: Within hours, major global shipping companies issued internal notices to urgently reassess the safety level of Hormuz Strait routes. Denmark’s Maersk announced it would re-evaluate insurance rates for certain routes and required all ships entering the Persian Gulf to raise their alert levels. Switzerland’s MSC began adjusting certain cargo ship routes to detour through safer waters further away. On the insurance side, war risk premiums for Persian Gulf voyages rose by approximately 15%.
Great Power Game Background: Iran’s latest statement comes amid renewed U.S.-Iran tensions. The U.S. has recently strengthened military deployments in the Middle East, including dispatching multiple warships and advanced warplanes to the Persian Gulf. Iran, through a series of “grey zone” actions — tanker seizures, announcements of maritime restricted zones, and now “control expansion” statements — has gradually expanded its presence in the Persian Gulf. Analysts note that the timing of Iran’s statement is highly targeted, aimed at pressuring Washington on the eve of the U.S. election.
Gulf States’ Reaction: Saudi Arabia, the United Arab Emirates, Qatar, and other Gulf states remained silent on Iran’s latest statement, but internal consultations have begun urgently. GCC sources revealed that member states are evaluating whether to issue a joint statement condemning Iran’s “unilateral actions.” Gulf states are both concerned that Iran’s move could affect international shipping safety, and worried that escalation could trigger larger-scale military conflict.
Panoramic Analysis
Iran’s declaration of expanded control over the Strait of Hormuz is an important signal of escalation in Middle East maritime competition. It is not only the latest round in the Iran-U.S. contest, but also a microcosm of a deep adjustment in the global energy landscape.
First, Iran’s “counter-strategy” enters a new phase. Over the past few years, facing maximum pressure from the U.S. and Israel, Iran has gradually built a complete “asymmetric counter” system. From early fast-attack craft swarms, to mid-stage tanker seizures and maritime drones, to now declaring “expanded control,” Iran’s counter-measures continue to escalate. The special nature of this statement is that Iran, for the first time, explicitly elevates “expanded control” as a formal diplomatic policy statement, meaning Iran has elevated maritime competition from the “action level” to the “policy level.” This shift reflects the Iranian decision-makers’ judgment — through rule declarations and legal means, strategic goals can be better achieved than through actual military action.
Second, the global “Hormuz premium” in energy markets is being reshaped. The Strait of Hormuz carries approximately 30% of global seaborne oil trade and 20% of LNG transportation — a true global energy chokepoint. Any “control escalation” statement by Iran transmits to the world through multiple channels including oil prices, freight rates, and insurance premiums. This time’s oil price surge of over 3% and gas price rise of over 4% reflect the market’s repricing of Strait of Hormuz risks. From a longer-term perspective, the “Hormuz premium” will gradually become the norm in global energy markets, which will have profound impacts on national energy security strategies, industrial production costs, and inflation levels.
Third, great power competition enters a “risk management” phase. The timing of Iran’s statement is intriguing — on the eve of the U.S. election. At this sensitive juncture, Iran intends to send a clear signal to both U.S. parties through shows of strength: any tough policy toward Iran will face comprehensive Gulf-region countermeasures. But at the same time, the U.S. response also displays “risk management” characteristics — neither showing weakness nor lightly escalating. This “restraint within competition” reflects a shared concern among great powers about direct conflict. Under the dual constraints of nuclear deterrence and energy dependence, the boundaries of great power competition are being redefined.
Fourth, the global energy transition faces “path reset” pressure. Iran’s repeated creation of tensions in the Strait of Hormuz objectively accelerates the urgency of global energy transition. On one hand, traditional oil and gas importers are forced to accelerate renewable energy deployment to reduce dependence on Gulf energy; on the other hand, investment in alternative energy technologies such as nuclear, hydrogen, and energy storage has significantly increased. Repeated turmoil in the Strait of Hormuz is becoming an important “catalyst” for the global energy transition — it reminds the world in the most direct way that the core of energy security lies not in resource reserves but in supply stability.
Multiple Perspectives
Iran’s Official Position: The Iranian Foreign Ministry emphasized that expanding control over the Strait of Hormuz is “Iran’s legitimate right as a coastal state” and consistent with international law. Iran’s permanent mission to the United Nations has sent a letter to the UN Secretary-General. The Secretary of Iran’s Supreme National Security Council posted on social media that “any provocation by foreign forces will face resolute response.” The Chairman of the Iranian Parliament’s National Security Committee emphasized that “the security of the Strait of Hormuz can only be guaranteed by Iran.”
U.S. Government Position: The White House National Security Council issued a statement expressing “grave concern” over Iran’s latest statement, emphasizing that “freedom of navigation in international waters cannot be violated.” The State Department announced it is coordinating “a unified position” with allies and may initiate condemnation of Iran through the UN Security Council or the International Maritime Organization. The Pentagon stated it “is prepared to respond to any contingencies,” including strengthening military deployments in the Persian Gulf.
Gulf Cooperation Council Position: The GCC Secretary-General issued a statement in Riyadh calling on all parties to “exercise restraint and avoid unilateral actions that could exacerbate tensions.” Saudi Arabia’s Foreign Minister emphasized in a call with the U.S. Secretary of State that “maintaining security and stability in the Gulf region is the shared responsibility of the international community.” The UAE called for resolving differences through diplomatic channels to avoid escalation.
European Union Position: The EU High Representative for Foreign Affairs issued a statement expressing “grave concern” over Iran’s latest announcement and calling on Iran to “abide by international law and avoid unilateral actions that could affect international shipping.” The EU also reiterated that “the principle of freedom of navigation is non-negotiable” and said it will maintain close coordination with the U.S. The EU also warned that energy market instability will harm the global economic recovery.
China Position: China’s Foreign Ministry spokesperson stated that “freedom of navigation and security in the Strait of Hormuz is crucial to the global energy market,” calling on all parties to “resolve differences through dialogue and consultation and avoid unilateral actions that could exacerbate regional tensions.” China also emphasized that as one of the world’s largest oil importers, it is highly concerned about developments in the Gulf situation and urges all parties to maintain international shipping lane safety.
International Energy Agency Position: The Paris-based IEA issued an emergency assessment report, noting that Iran’s latest statement could lead to a short-term reduction in global oil supply of hundreds of thousands to millions of barrels per day. The report called on major oil-consuming countries to activate strategic reserve release mechanisms to stabilize market expectations.
