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

Turkey (Shakarab consideration)

Ankara serves as one of two Western-adjacent Iran back-channels while Turkish national Gholamreza Khani Shakarab faces imminent execution on espionage charges in Iran. President Erdogan cannot deflect the domestic political crisis that a Turkish execution would trigger, which would force suspension of the mediating role.

Germany (Bundestag gap)

Belgium, Germany, Australia, and France committed Hormuz coalition hardware on 18 May. Germany's Bundestag authorisation for the coalition deployment remains pending, creating a constitutional gap between the commitment announced and the parliamentary mandate required to operationalise it.

IEA and oil market analysts

The IEA's $106 May Brent projection met the market in one session on 20 May as Brent fell 5.16% on diplomatic optimism. Goldman Sachs and Morgan Stanley's two-layer premium framework holds: the kinetic component compressed; the structural insurance component tied to Lloyd's ROE remains unresolved.

Hengaw

Documented the dual Kurdish execution at Naqadeh on 21 May, the two Iraqi-national espionage executions on 20 May, and Gholamreza Khani Shakarab's imminent execution risk. The 24-hour cluster covers two executions at one facility, the first foreign-national espionage executions, and a Turkish national whose death would suspend Ankara's mediation.

Lloyd's of London

Hull rates stand at 110-125% of vessel value on the secondary market; the Joint War Committee has conditioned cover reopening on written ROE from the coalition or PGSA. The Majlis rial bill makes any compliant ROE structurally impossible to draft while the PGSA's yuan portal remains its operational mechanism.

United Kingdom and France (Northwood coalition)

The 26-nation coalition paper requires Lloyd's to see written rules of engagement before Hormuz war-risk cover reopens. The Majlis rial bill adds a second governance incompatibility on top of the unpublished PGSA fee schedule; coalition ROE cannot mention rial without conceding Iranian sovereignty over the strait.
