Key takeaway

Iran is converting Hormuz from a blockade into a bilateral licensing system it controls.

Iran exempted Iraq from all Strait of Hormuz restrictions on 5 April, citing "brotherly" ties. ¹ Iraq's oil production had collapsed from 4.3 to 1.2 million barrels per day under the blockade, a 72% drop costing roughly $200 million daily. Oil is the single revenue source that funds Iraq's government. The exemption is a survival measure for both sides: Iraq's economy cannot function without Hormuz access, and Iran needs at least one friendly neighbour whose state has not been destroyed by Iranian policy.

Weekly Hormuz transits rose to 53 last week, up from 36, but still down over 90% from the pre-war normal of roughly 966. The increase is driven entirely by bilateral exemptions: the Philippines, France , Japan, Oman, and now Iraq. Each deal further normalises Tehran's sovereignty claim over international waters. The coalition posture Washington maintained since the blockade began is dissolving into a series of licensing arrangements administered by Tehran.

Ali Vaez of the International Crisis Group assessed that Hormuz control is "much more potent than even a nuclear weapon." Former CIA Director Bill Burns said Tehran has "tasted its power and leverage and won't soon give it up." US intelligence simultaneously assessed Iran will not open Hormuz "any time soon." ²

Deep Analysis

In plain English

Iran is blocking most ships from passing through a narrow waterway that most of the world's oil passes through. Iraq, which is Iran's neighbour and has historically friendly relations with Tehran, was losing three-quarters of its oil income because of the blockade. Iran has now said Iraq's ships can pass through. This sounds like a concession, but it is actually something more significant: Iran is deciding country by country who gets to use an international waterway, and charging them for the privilege. That is a fundamental change in who controls global oil shipping.

Primary parallel: The Allied blockade of Germany in World War I — initially comprehensive, progressively eroded by neutral exemptions for Scandinavian states, ultimately maintained as an instrument of pressure through selective enforcement. The Hormuz bilateral exemption system follows the same structural trajectory: a nominally total blockade converting into a managed licensing regime administered by the blocking power.

Counter-parallel: US oil sanctions on Iran from 2018 — also built around bilateral exemptions for India, China, South Korea, and others. Those exemptions steadily eroded the sanctions architecture until they were eliminated. Iran appears to have learned from watching its own sanctions erosion and is now applying the exemption model offensively.

Iraq's 72% oil production collapse from 4.3 to 1.2 million barrels per day costs Baghdad approximately $200 million daily. Oil is Iraq's sole material revenue source, funding 90% of government expenditure. Without Hormuz access, Iraq faces a fiscal crisis within weeks.

The exemption does not restore Iraq's full production: ships must still transit the Larak Island IRGC corridor, paying in Iranian rial. Each Iraqi barrel that transits contributes to the 53 weekly transits counted last week, still down 90% from pre-war baseline. The economic relief is partial; the political signal to Arab states watching the bilateral exemption system is total.

Consensus view: International Crisis Group's Ali Vaez and former CIA Director Bill Burns both assess that Iran will not relinquish Hormuz control voluntarily, having assessed the strait as more strategically valuable than its nuclear programme. Each bilateral exemption reinforces this assessment by demonstrating that Tehran can manage the blockade selectively without global coalition forming against it.

Counter-view: Carnegie Endowment's Karim Sadjadpour argues the Iraq exemption exposes a structural flaw in Iran's Hormuz strategy: a blockade that Iran must selectively abandon to prevent the economic collapse of its closest ally is not a sustainable strategic instrument.

Key tension: Whether Iran's bilateral exemption system is a sign of Hormuz leverage being strategically managed or of the blockade becoming unworkable under its own weight.

Different Perspectives

Oil traders

Sent Brent down 2.29 per cent to $98.38 a barrel on reports that mediation was reviving, moving the price on CENTCOM's quiet night rather than on Trump's same-day promise of a bigger operation with no deadline attached.

Iran

An Iranian official called the same mediation account completely misleading, denying it received any US proposal via Baghdad on the same day Iraq denied delivering one, leaving neither denial able to settle what actually passed between the two capitals.

Iraq

Called groundless the New York Times account that its prime minister carried a US ceasefire proposal to Tehran, a denial that also protects Baghdad's effort to avoid becoming a party to a war fought by aircraft it does not control.

OHCHR

Recorded 17 civilian seafarer deaths since the war began, a population neither the Pentagon nor Iran's Health Ministry counts in its own tally, and called for urgent action on 6,000 crew stranded across roughly 400 vessels in the Strait of Hormuz.

Houthis

Enforced the blockade on Saudi-linked shipping it declared on 20 July by hitting the NCC Masa and then an Aramco facility at Jazan, moving from radio warnings to strikes on land after four days without a confirmed hit.

Saudi Arabia

Struck Houthi military sites near Hodeidah the same day the NCC Masa was hit, while its coalition spokesman insisted Hodeidah, Ras Issa and Salif all remain open to navigation. The distinction protects the ports Yemen's population depends on for food and fuel even while punishing the group behind the tanker strike.
