Pentagon downplays Hormuz blockade as shipping data shows 90% collapse

Defense Secretary Hegseth insists strait remains 'open' while AIS tracking reveals Iran controls traffic through selective toll system, exposing stark credibility gap as oil markets price $200/barrel scenarios.

Defense Secretary Pete Hegseth told reporters on 31 March that the Strait of Hormuz is ‘open for transit’ and faces no problems except ‘Iran shooting at shipping,’ even as maritime intelligence shows vessel transits running 90% below baseline and Iran operating a selective toll-booth regime that grants passage only to pre-approved vessels.

The gap between Pentagon messaging and observable reality has widened into a credibility crisis at precisely the moment energy markets are pricing catastrophic scenarios. Shipping data from Lloyd’s List Intelligence documents just 48 cargo vessels (over 10,000 deadweight tonnage) transiting between 23-30 March, compared to a historical average of 138 vessels per day. Between 1-25 March, total transits reached 142 — down from 2,652 during the same period in 2025.

The toll-booth reality behind ‘open’ claims

What Hegseth describes as an open waterway is actually an Iranian-controlled checkpoint system. Since mid-March, the Islamic Revolutionary Guard Corps has operated what maritime analysts call a ‘toll booth’ — pre-vetting vessels, charging fees in Chinese yuan, and granting passage exclusively to ships from nations Tehran deems non-hostile. By 26 March, Lloyd’s List documented 26 vessels transiting via this approved route through Iranian territorial waters, with Iranian-affiliated vessels comprising the majority of late-March traffic.

‘This is very unprecedented,’ Timer Raanan, a maritime risk analyst at Lloyd’s List, told USNI News. ‘This is not how things were moving prior to the war, and it’s a really disturbing development in terms of Iran exerting control over traffic through the strait.’

The selective passage regime operates alongside continued kinetic threats. Iranian forces have struck or nearly hit 24 vessels since 28 February. While an 11-day lull occurred mid-March, a tanker was struck on 30 March and a projectile splashed near a container vessel the same day, according to shipping intelligence compiled by USNI News.

Administration signals shift away from reopening objective

The Pentagon’s rhetorical minimisation coincides with a substantive policy shift. White House Press Secretary Karoline Leavitt stated on 30 March that reopening the Strait of Hormuz is not a ‘core objective’ for ending the military campaign against Iran, signalling President Trump’s willingness to declare victory without restoring the waterway to normal operations. The statement, reported by Time, marks a departure from earlier administration rhetoric about ensuring freedom of navigation.

‘We have been dealing with it, and don’t need to worry about it.’

At a 31 March Pentagon briefing, Hegseth doubled down on dismissive framing, telling reporters: ‘It’s not just the United States Navy. Last time I checked, there was supposed to be a big, bad Royal Navy. They’d be prepared to do things like that as well.’ He added that the strait ‘is not just a United States of America problem set’ and suggested other countries ‘might want to start learning how to fight for yourself,’ per CNN.

Energy executives warn of mid-April reckoning

Pentagon reassurances clash with industry consensus that time is running out. Oil executives told CNBC at the CERAWeek conference that the strait must reopen by mid-April — within two weeks — to prevent escalating supply disruptions and potential physical shortages across Europe and Asia.

‘There are very real, physical manifestations of the closure of the Strait of Hormuz that are working their way around the world,’ Chevron CEO Mike Wirth said on 30 March. Shell’s CEO echoed the warning, with both executives pointing to inventory drawdowns that have buffered markets but cannot sustain indefinitely.

Supply disruption mechanics

The strait normally handles 20% of global oil supply. Current disruption estimates reach 4.5-5 million barrels per day through 19 April — roughly 5% of world supply. BCA Research analyst Marko Papic projects this loss will double by mid-April, becoming the largest crude supply loss on record if Iranian control persists.

Paola Rodriguez-Masiu, chief oil analyst at Rystad Energy, told CNBC that markets have shown ‘remarkable resilience’ for four weeks, supported by pre-war surplus and crude-on-water inventories. ‘That phase is now ending,’ she said. US crude hit $99.64 per barrel on 27 March, up more than 45% since the conflict began 28 February. Brent reached $126 at its 8 March peak before settling near $112.57 by late March.

Wall Street pricing $200 scenarios

Interviews with 36 oil traders, executives, brokers and shippers conducted by Bloomberg reveal deepening concern about a crisis the administration appears reluctant to acknowledge. Multiple participants said Wall Street and government officials are actively modelling scenarios where crude reaches $200 per barrel if the blockade extends into late April or May.

Market warning signals
  • US gasoline averaged $4.00/gallon as of 31 March, with further increases expected if supply tightens
  • Asian refiners face potential crude shortages by mid-April as floating storage depletes
  • European diesel markets already showing scarcity pricing as Middle East supplies reroute or halt
  • Industry consensus: prolonged closure would surpass 1970s oil shock in economic impact

‘The world still hasn’t grasped the severity of the situation,’ was the consensus view among traders interviewed by Bloomberg. Many drew parallels with the 1970s oil shock, warning a prolonged closure would threaten an even bigger crisis.

Credibility cost of rhetorical downplay

The divergence between Pentagon statements and shipping data creates a secondary crisis of market confidence. When official sources minimise observable disruptions, traders and executives lose trust in government assessments — potentially accelerating speculative price spikes or prompting uncoordinated national responses that fragment global energy markets.

Analysis from the Washington Institute documents Iran’s evolving strategy: rather than total closure, Tehran operates a profit-generating control mechanism that allows friendly traffic while strangling Western supply chains. This approach gives Iran economic leverage and diplomatic flexibility while complicating military responses that presume a binary open-or-closed framework.

Hegseth’s repeated assertions that the waterway is ‘open’ except for Iranian attacks ignore this strategic evolution. The toll-booth system represents a form of coercive control that falls between free passage and outright blockade — a grey zone that Pentagon messaging appears unwilling or unable to acknowledge.

What to watch

The mid-April timeline cited by energy executives creates a hard deadline for policy decisions. If the administration maintains its current stance — treating strait reopening as non-essential while publicly downplaying disruption severity — markets will face their first real test as inventory buffers expire. Watch for: divergence between White House rhetoric and emergency energy measures (SPR releases, refinery waivers); European or Asian unilateral naval deployments if US commitment remains ambiguous; and whether Iran expands its toll-booth regime or reverts to broader attacks if the US-Israel campaign winds down without addressing maritime control. The gap between what officials say and what shipping data shows will narrow sharply once physical shortages hit retail fuel markets — likely within 10-14 days.
