Iran partially closed the strategically vital Strait of Hormuz during high-stakes military drills conducted by the nation’s powerful Revolutionary Guard. Furthermore, state media reported that the closure stemmed from essential security precautions. Tehran is continuing its latest operational readiness exercises in the waterway.
This rare tactical move occurred during significant diplomatic talks in Geneva. Representatives from both the United States and Iran participated in these talks. These ongoing discussions aim to resolve a long-standing and complex dispute over Tehran’s nuclear program. This issue remains a primary source of regional tension. Notably, this event marks Iran’s first restriction of parts of the waterway. This has not happened since President Trump threatened military action earlier in January.
The Global Impact of the Strait of Hormuz
The Strait of Hormuz remains the world’s most significant oil choke point. It links major Middle Eastern producers with essential energy markets across the globe. Currently, data from market intelligence firm Kpler indicates that about 13 million barrels of crude oil moved through this passage daily in 2025. This substantial amount highlights the importance of this route to the global energy supply. This massive volume represents roughly 31% of all global seaborne crude flows. Any disruption is a major concern for the international community.
The strait is recognized as an international waterway. However, Iran and Oman control the territorial waters along its narrow 21-mile-wide maritime passage. Furthermore, the US Energy Information Administration warns that most oil transiting the area has no viable alternative route. This is despite the existing regional pipelines.
Military Readiness and Diplomatic Progress
Tuesday’s temporary closure specifically aimed to ensure shipping safety during the Revolutionary Guard’s intensive “Smart Control of the Strait of Hormuz” military drill. This exercise helps improve Iran’s operational readiness and bolsters its deterrence capabilities against potential foreign threats while testing new maritime defense strategies.
Additionally, Iranian Foreign Minister Abbas Araghchi stated that both parties reached an understanding of guiding principles after the high-level negotiations finally concluded. While Iran has previously harassed shipping in the strait, it has not fully closed the waterway since the end of the Iran-Iraq war. Even during the intense 12-day war last year, the waterway remained open despite significant bombardments of various Iranian military and nuclear sites.
