Iran's five peace terms: Hormuz first

2 min read

Tehran published five conditions for ending the war. The fifth, permanent control of the Strait of Hormuz, would rewrite international maritime law.

Key takeaway

Iran is legislating Hormuz control into permanent law before any ceasefire.

Iran's stated terms for ending the war, relayed through PressTV on 25 March via a senior political-security official, are: (1) complete cessation of all attacks; (2) concrete security mechanisms preventing reimposition of war; (3) guaranteed reparations; (4) end of war across all fronts for all resistance groups; and (5) recognition of Iran's right to control the Strait of Hormuz. 1

Condition five is not a ceasefire demand. Under UNCLOS, the strait of Hormuz is an international waterway; Iran may regulate transit through its territorial waters but cannot claim sovereignty over passage itself. No US administration could accept this. Iran almost certainly knows that.

Western coverage has framed Iran as simply "refusing talks" . The five-condition structure tells a different story: Iran has a formal position, and its most consequential demand is being legislated domestically through the Majlis bill and formalised internationally through the IMO notification . Iran is building legal architecture to outlast the war, following the same model Egypt used after Suez in 1957: establish physical control during a crisis, then legislate before it ends.

Deep Analysis

In plain English

Iran has published five demands it says must be met before it will stop fighting. The first four involve ceasefire terms and compensation. The fifth is different: Iran wants permanent legal recognition that it controls the Strait of Hormuz, the narrow passage through which most of the Persian Gulf's oil leaves. Under current international law, the strait is an international waterway. Every country's ships have the right to pass through it. Iran cannot legally block that passage, even though the water runs alongside its coast. Iran's fifth condition would change that law. No US president can agree to this. And Iran almost certainly knows that. The more telling detail is that Iran is not just saying it; it is also passing a law in its parliament to formalise the toll regime, and filing paperwork with the international shipping body. Iran is building the legal infrastructure of permanent control while the war is still ongoing.

Deep Analysis
Root Causes

Iran's Hormuz sovereignty demand is thirty years in development. Tehran has consistently argued since the 1994 Law of the Sea negotiations that its territorial waters include the strait's northern half, and that innocent passage rights are not absolute for warships of hostile states. The IRGC's toll infrastructure built between 2015 and 2025 was designed to create an operational fact before any legal claim was tested.

The war created the opportunity to formalise what the IRGC had been building. The Majlis toll bill and the IMO notification are the legal superstructure on top of an operational infrastructure that already exists.

What could happen next?
  • Consequence

    Iran's five conditions remove diplomatic off-ramps: any deal requires accepting demands that no allied government can publicly endorse, guaranteeing talks collapse if aired publicly.

  • Precedent

    If the Majlis bill passes before a ceasefire, the Hormuz toll regime becomes Iranian domestic law that any future government would need to repeal, entrenching the leverage beyond this war.

Different Perspectives
Turkey (Shakarab consideration)
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)
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.

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.

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.

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.

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.
