Iran's head of the Parliament's Civil Engineering Commission says that the Strait of Hormuz is completely under Iran's control, adding that they are increasing speed of oil price growth in the coming days.

Rhetoric of this kind from Iranian officials on the Strait of Hormuz is a recurring feature of periods of elevated tension, and it has historically been a signaling tool rather than a precursor to actual closure: the strait has never been durably shut, because doing so would cut Iran's own crude exports and invite direct military response from the US and Gulf states. The transmission channel in past episodes runs through the front of the crude curve, freight rates, tanker insurance premia, and options skew rather than through any change in physical flows, with Brent typically carrying a larger geopolitical premium than WTI given its waterborne exposure. The speaker's institutional role matters: statements from parliamentary commission heads carry less weight than those from the Supreme National Security Council, the IRGC Navy, or the Supreme Leader's office, and markets have tended to fade comments from lower-tier officials absent corroboration. The distinction worth drawing is between harassment and interdiction of individual tankers, which has occurred repeatedly and produced transient spikes, and an attempt at closure, which would be a categorically different event. The follow-ons that have historically mattered are any matching statements from the IRGC, tanker traffic data through the strait, war-risk insurance quotes, and whether Western or Gulf naval posture changes. As it stands this is rhetoric, and the established pattern is for such remarks to add a modest premium that decays without physical escalation.
