A US intelligence report has indicated that Iran possesses a significantly enhanced capability to disrupt or effectively close access to the Strait of Hormuz, a critical global energy chokepoint.
According to multiple sources familiar with the findings, this development has reshaped how Washington views Tehran’s strategic leverage, particularly in the aftermath of recent military tensions and maritime disruptions in the region.
Intelligence officials believe Iran has demonstrated both the intent and operational means to obstruct maritime traffic through the strait when it chooses, raising concerns that such a move could be repeated in future crises.
“We have now handed Iran de facto control over the strait – a weapon more powerful than any nuke,” CNN quoted one of the sources familiar with the US intelligence assessments, emphasising how the war has fundamentally altered Tehran’s thinking about leveraging similar tactics in the future.
Although a framework understanding has been reached to restore open passage as part of broader negotiations, analysts warn that Iran has already shown it can interrupt flows of commercial shipping and energy exports when it deems it strategically useful.
Some sources involved in the assessment argue that this effectively grants Iran a form of coercive control over one of the world’s most important oil transit routes, significantly increasing its geopolitical leverage. The ability to threaten global energy supplies is now seen as a central pillar of Iran’s asymmetric strategy, alongside its capacity to target regional energy infrastructure and use fast-attack naval craft, missiles, drones, and mine-laying tactics to pressure adversaries.
U.S. officials acknowledge that negotiations over reopening and securing the waterway underscore Iran’s bargaining power, even as Washington seeks to tie economic or political concessions to the uninterrupted flow of shipping.
However, there is no consensus within the intelligence community on how frequently or decisively Iran would exercise this capability going forward, with some analysts warning that its demonstrated success may embolden future action.
One of the main reasons Iran believes it can continue to weaponise the strait is that it still retains a significant portion of its weapons stockpile, including missiles, drones, missile launchers, and hundreds of small, fast boats that continue to harass shippers attempting to transit the waterway and can be used to lay mines. Iran has also been rebuilding its military industrial base faster than the US anticipated and has already begun new drone production, CNN reported.
Complicating matters further is Iran’s reported ability to influence other forces in the region, including groups capable of disrupting another key maritime corridor connecting the Red Sea to the Indian Ocean. This raises the possibility of coordinated pressure on multiple global shipping routes, which officials say would have severe consequences for international trade and energy markets.
U.S. planners are also reassessing earlier assumptions that Iran would be deterred by the risk of economic retaliation or international isolation. Instead, recent assessments suggest Tehran calculated that temporary disruption of the strait would generate strategic leverage rather than unsustainable costs, particularly given its stockpile of naval and missile assets.
As a result, Washington now faces a more complex strategic environment in which Iran’s ability to weaponise maritime geography is treated as an enduring feature of regional security rather than a temporary wartime development.
