Iran Says It Temporarily Closed Strait of Hormuz During Indirect U.S. Talks
Lead: Iran announced on Tuesday that it briefly closed the Strait of Hormuz for live-fire drills as negotiators held another round of indirect talks with U.S. representatives in Geneva. The government said missiles were fired toward the waterway and that the strait would be closed for several hours for “safety and maritime concerns,” though independent confirmation of a full closure was not immediately available. The move—said to be a rare first since the U.S. began stepping up threats and sending military assets—comes amid fragile progress in talks aimed at resolving disputes over Iran’s nuclear program and has heightened fears of regional escalation.
Key Takeaways
- Iran announced the temporary closure of the Strait of Hormuz on Tuesday during live-fire drills; the strait carries about 20% of global oil shipments.
- Iranian state media reported missiles fired toward the strait and a closure for “several hours,” but outside verification of a full closure was not available at the time of reporting.
- Negotiations in Geneva involved indirect U.S.–Iran talks hosted inside the Omani envoy’s residence; Trump envoys Steve Witkoff and Jared Kushner led the U.S. side.
- Iranian Deputy Foreign Minister Abbas Araghchi described the talks as opening “a new window” and said Iran will submit more detailed proposals in the next two weeks.
- Supreme Leader Ayatollah Ali Khamenei warned the United States against coercion and said even the world’s strongest military could be significantly struck.
- The U.S. recently augmented its regional force posture, sending the USS Gerald R. Ford to join the USS Abraham Lincoln carrier strike group.
- Oil benchmarks fell after the talks: U.S. crude was reported down about 1.3% at $62.06 per barrel and Brent off roughly 2.3% at $67.03 per barrel.
Background
The Strait of Hormuz is one of the world’s most consequential maritime chokepoints: roughly 20% of global crude oil trade transits the narrow passage between the Persian Gulf and the Gulf of Oman. Control or disruption of the strait has historically carried major economic and strategic consequences. During the 1980s Iran–Iraq war, Iran mined the waterway and temporarily restricted passage, a precedent analysts cite when assessing Tehran’s latest announcement.
Diplomatic engagement between the United States and Iran has been intermittent since the U.S. withdrawal from the 2015 nuclear accord. Months of meetings resumed recently with indirect exchanges aimed at limiting Iran’s nuclear activities and addressing sanctions and security concerns. Regional actors such as Oman have repeatedly acted as intermediaries; the latest Geneva talks were hosted inside the Omani envoy’s residence, reflecting Oman’s long-standing mediator role.
Main Event
On Tuesday Iranian state media reported that the Islamic Revolutionary Guard Corps began live-fire exercises in the Strait of Hormuz, the Persian Gulf and the Gulf of Oman, announcing missile launches and a temporary closure of the strait for “safety and maritime concerns.” Officials said the closure would last several hours, though maritime authorities and independent trackers had not immediately confirmed a full, sustained shutdown of the shipping lane.
Iran’s foreign minister for disarmament, Abbas Araghchi, who led Tehran’s delegation in Geneva, took a more conciliatory tone after the talks, saying a “new window has opened” and expressing hope the process could yield a sustainable negotiated settlement. He also met with International Atomic Energy Agency Director-General Rafael Grossi in Geneva to discuss the agency’s possible role in monitoring or facilitating steps toward an agreement.
Supreme Leader Ayatollah Ali Khamenei issued a separate, more defiant message, warning the United States against preemptively forcing outcomes and asserting that even the world’s strongest military could be struck in ways that would be hard to recover from. Meanwhile, U.S. President Donald Trump said he planned to remain involved in the process and has previously ordered additional military assets—most recently the USS Gerald R. Ford—to the region.
Analysis & Implications
The announced temporary closure underscores Tehran’s willingness to use maritime measures as political signaling. If the strait was indeed closed even briefly, the action would represent an escalation in tactics beyond routine exercises that occasionally impede traffic. For global markets, any real or perceived threat to the Hormuz transit route can spike oil volatility; the immediate market reaction in this case was downward on hopes the diplomatic track might reduce longer-term supply risk.
Strategically, Iran’s move serves multiple audiences: domestic publics, regional rivals and international interlocutors. Domestically it projects resolve; regionally it signals to Gulf Arab states and Israel that Iran can impose costs on global commerce; internationally it reminds external powers that strikes on Iranian facilities could produce wide-ranging consequences. This raises the risk of miscalculation—especially where U.S. and Iranian forces now operate in closer proximity.
Diplomatically, the simultaneous mix of tough rhetoric and cautious negotiation complicates prospects. Progress reported by negotiators—paired with Iran’s pledge to offer more detailed proposals—keeps a diplomatic opening alive, but the use of military demonstrations as leverage could harden positions and shrink room for compromise. The IAEA’s involvement remains critical: effective verification mechanisms would be essential to any durable deal and to calming market and regional anxieties.
Comparison & Data
| Item | Recent Figure / Fact |
|---|---|
| Share of world oil via Hormuz | About 20% |
| U.S. crude price (reported) | $62.06 per barrel (down ~1.3%) |
| Brent crude price (reported) | $67.03 per barrel (down ~2.3%) |
| U.S. carrier presence | USS Gerald R. Ford + USS Abraham Lincoln strike group |
The table summarizes immediate data points tied to the story. The roughly 20% of seaborne oil passing through Hormuz makes the strait a determiner of market sentiment. Short-term oil price moves can reflect news-driven sentiment and expectations about supply disruption; longer-term trajectories will depend on whether negotiations yield constraints on Iran’s enrichment or on broader geopolitical stability in the region.
Reactions & Quotes
Officials and analysts responded in sharply different tones—diplomatic engagement on one hand, and stark warnings on the other.
“A new window has opened” for a negotiated solution, said Iran’s Abbas Araghchi after the Geneva meetings, framing the talks as cautiously promising while noting significant gaps remain.

Unconfirmed
- Whether the Strait of Hormuz was completely and continuously closed for the announced period remains unverified by independent maritime tracking at the time of the initial reports.
- The specific scope, targets and accuracy of the missiles Iran reported firing toward the strait have not been independently corroborated.
- Details of the additional proposals Iran said it will submit in the next two weeks were not publicly shared and thus remain unknown.
Bottom Line
The temporary closure announcement was both a tactical show of force and a strategic signal: Tehran sought to demonstrate leverage while keeping a negotiating channel open. That dual track—simultaneously hard and diplomatic postures—raises the probability of friction, misinterpretation or unintended escalation even as negotiators report limited progress.
For observers, the immediate questions to watch are whether the IAEA is given clearer access or monitoring roles, whether Iran follows through with the promised detailed proposals, and whether U.S. military deployments and Iranian maritime measures result in closer operational encounters. Markets may react quickly to any credible disruption to Hormuz; policymakers will need to balance pressure and diplomacy to prevent a wider crisis.
