With Iran Setting Limits, Strait of Hormuz Remains Thorny Politically
Iran has imposed strict controls on the Strait of Hormuz, including tolls and selective access, amid ongoing US-Iran tensions following a fragile ceasefire. These measures assert Iran’s maritime sovereignty but keep the waterway politically volatile.
Crisis Background
The 2026 Strait of Hormuz crisis erupted in late February when US and Israeli strikes killed Iran’s Supreme Leader Ali Khamenei, prompting Iran to block shipping through missile attacks, mines, and warnings. Previously handling 25% of global seaborne oil, the strait saw traffic plummet, with insurance rates surging and attacks on 21 merchant ships. A two-week ceasefire in early April allows limited passage under Iranian terms, but full reopening remains uncertain.

Iran’s Limits and Toll System
Iran’s IRGC enforces a “toll booth” regime: ships submit manifests, crew details, and IMO numbers for vetting, then receive clearance codes and IRGC escorts via a single corridor. Tolls reach $2 million per vessel in Chinese yuan for non-allies, free for “friendly” nations, funding reconstruction while banning US and Israeli ships. Iran plans to formalize this via parliament, rejecting full international access.
Political Tensions
President Trump issued warnings against the tolls, threatening strikes on Iranian infrastructure, while Iran demands sanctions relief and compensation in a 10-point peace plan. Negotiations via Pakistan continue, but post-ceasefire, few vessels pass without authorization, risking escalation. Analysts note military reversal is risky, favoring diplomacy amid global energy volatility.
