Iran’s leverage over the Strait of Hormuz is waning as oil flows recover and costs mount at home

Six months after major disruptions tied to the conflict, the Strait of Hormuz is not back to normal, but it is moving toward partial recovery. Market-tracking firm Kpler estimated average daily Hormuz clearance at 13.19 million barrels in the week to Sept. 27, about 77% of the prewar 17.13 million barrels per day baseline. That recovery matters because it shows buyers and producers finding ways to route and transport oil despite ongoing risks.

Gulf oil producers and international shipping operators have adjusted routes, schedules and security measures. Buyers have sourced supply through alternative pipelines and regional storage. Naval presence and coordination by the United States and Gulf partners have helped keep shipments moving. These operational responses reduce Tehran's capacity to turn disruptions into lasting bargaining leverage over sanctions relief or other concessions.

Continuing pressure on the strait has economic consequences for Iran itself. Sustained military and naval operations, reprisals and countermeasures, and constrained oil revenue all weigh on Tehran's finances. Those domestic costs shrink the range of sustainable pressure Iran can apply over time, weakening any bargaining position that rests solely on disrupting maritime trade.

Despite partial recovery, two constraints remain. First, flows are still below prewar levels and subject to episodic attacks, seizures or threats that can spike market volatility. Second, opaque shipping behavior—such as turning off tracking transponders—keeps uncertainty high and raises the chance of miscalculation. These factors mean Hormuz remains a strategic lever, but one whose practical effectiveness is reduced as the rest of the region adapts.

Implications for diplomacy and conflict dynamics

The strait has become central to negotiations and military planning surrounding the wider war. With its leverage declining, Tehran may seek alternative pressure points, including influence over other shipping routes and allied proxies. For Washington and Gulf states, the immediate policy priority is maintaining diversified routes and resilient logistics to keep energy markets functioning while limiting escalation.

Iran can still disrupt Hormuz and periodically affect markets, but data and operational changes show the world is learning to live with a constrained strait. The partial recovery in flows and mounting domestic costs for Tehran reduce, though do not eliminate, the utility of the strait as a tool for extracting concessions.
