Iranian Parliament Speaker Ghalibaf says Iran’s armed forces have full control of the Strait of Hormuz, claimed US-backed vessels attempting to pass are being confronted, and said recent attacks on Iran were met with a “devastating response"

• "America wants to pass through the southern route of the Strait of Hormuz against the agreement, which we will not allow."

Statements of control over the Strait of Hormuz from senior Iranian officials recur whenever tensions with the US escalate, and the established market distinction is between rhetorical assertion and physical interference: crude and product pricing has historically repriced only when tanker transits are actually disrupted, seized, or insured against at sharply higher war-risk premia, not on parliamentary rhetoric alone. The transmission channel is well known: a large share of seaborne crude and LNG passes the strait, so the relevant tells are tanker tracking, freight and insurance rates on Gulf loadings, and any rerouting or convoying by naval forces, rather than official statements. The reference to a "devastating response" to recent attacks fits the familiar tit-for-tat sequencing in which each side signals resolve while stopping short of closing the waterway, since a genuine closure would cut Iran's own exports and invite direct military confrontation, a threshold never sustained in past episodes. Worth watching is whether the claim about confronting "US-backed vessels" corresponds to verifiable interceptions, and whether shipping companies or flag states alter behaviour, since those operational moves, not the rhetoric, are what have previously moved the front of the crude curve and Gulf benchmarks. As it stands this is a headline-risk event of a type that has typically faded absent physical confirmation.
