**Summary**: Iran’s parliament has approved charging fees on ships transiting the Strait of Hormuz and, via state media, warned at 20:48 UTC that any country joining a new US sanctions package will be treated as declaring war. The tandem of legal-economic leverage over the world’s key oil chokepoint and escalatory war rhetoric materially raises the risk of energy supply disruption and miscalculation between Iran, the US, and Gulf exporters.

## Detail

Iran has taken a concrete step toward monetizing – and potentially weaponizing – control of the Strait of Hormuz while hardening its stance on Western pressure. At approximately 20:44 UTC on 23 August, Iranian state-linked channels reported that parliament had approved a measure to charge ships fees for passing through the Strait of Hormuz. Minutes later, around 20:48 UTC, state media amplified a warning that any country joining a new US sanctions package would be treated by Tehran as having declared war.

The two moves, reported inside a half-hour window, shift Iran’s posture from rhetorical threats to a legal and political framework that could justify tighter control over one of the world’s most critical energy arteries. About a fifth of globally traded crude and a major share of LNG exports from Qatar traverse the Strait. While some Gulf states have limited bypass capacity via pipelines to the Red Sea or domestic refineries, there is no scalable substitute for Hormuz for bulk seaborne exports.

For shipowners, crews, and energy importers in Asia and Europe, this combination matters immediately. A formal fee regime introduces a new, Iran-controlled cost and compliance layer for transit, with uncertainty over enforcement, currency of payment, and sanctions exposure. The ‘declaration of war’ framing against any state that joins future US sanctions raises the perceived risk that commercial shipping flying those states’ flags or insured in their jurisdictions could be singled out for detention, inspection, or harassment under the guise of enforcing Iranian law or retaliating against ‘belligerents.’ Insurers, P&I clubs, and charterers will be forced to reassess war risk premiums and routing assumptions on very short notice.

For security planners, the measure provides Tehran a legalistic cover to increase its physical presence around the Strait, including more frequent boardings and ‘fee enforcement’ stops by the IRGC Navy. That increases the probability of dangerous encounters with US, UK, and Gulf naval escorts and with commercial vessels linked to sanctioning states. Iran has previously seized or diverted tankers in response to asset seizures and sanctions; a fee regime combined with war rhetoric could normalize these actions as ‘customs’ or ‘port dues’ disputes, complicating escalation management.

Market pressure points are clear: crude and product benchmarks are likely to price a higher risk premium, particularly for sour grades tied to Gulf exports, while LNG markets may see renewed volatility given Qatar’s dependence on Hormuz. A sustained perception of elevated transit risk would lift shipping and insurance costs globally, potentially widen timespreads in oil, and support a bid in traditional safe havens such as gold and the US dollar. Gulf sovereign spreads could also feel incremental pressure if investors price in a higher probability of sanctions tit-for-tat affecting regional infrastructure.

Over the next 24–48 hours, focus should be on: (1) the exact legal text and implementation details of the Iranian fee regime, including who is exempted and how payments are collected; (2) public responses from the US, EU, and key Asian importers such as China, Japan, and South Korea, particularly on whether they consider the fee compatible with international maritime law; (3) any observable change in IRGC or Iranian Navy posture or boarding activity in and around Hormuz; (4) insurance industry guidance on war risk premiums and coverage conditions for transiting ships; and (5) signs that Washington is finalizing or announcing the ‘new sanctions package’ referenced in Iranian media, which would test whether Tehran is prepared to operationalize its ‘declaration of war’ warning beyond rhetoric.

**MARKET IMPACT ASSESSMENT:**
High risk of higher oil and LNG risk premia, flatter safe-haven bid (gold, USD), and pressure on Gulf shipping and insurance costs as markets price increased probability of targeted disruptions or harassment in the Strait of Hormuz.
