Iran's IRGC threatens to target US bases if commercial ships continue transiting Strait of Hormuz, according to.

Threats against shipping through the Strait of Hormuz are a recurring feature of Iran's coercive signalling and have historically been priced as tail risk rather than base case: past episodes of IRGC rhetoric of this kind have tended to lift the prompt crude premium and tanker insurance and freight costs while actual closure attempts have never materialised, largely because closing the strait would cut off Iran's own export route and invite a direct military response. The conditional structure here matters: the threat is tied to continued commercial transit, which inverts the usual logic of a blockade threat and reads more as an attempt to deter traffic and raise costs than to halt flows outright. The established transmission channel is the war-risk insurance premium and tanker rates first, the front of the crude curve second, with the strait's share of seaborne oil supply making even marginal disruption material. What distinguishes noise from signal in these episodes is follow-through on the water: harassment or seizure of vessels, GPS interference, or actual kinetic incidents, as opposed to statements carried through state-linked channels. The actors' prior form favours calibrated pressure over escalation, but miscalculation risk in past Hormuz episodes has come from localised incidents rather than declared intent. Worth watching are ship-tracking and transit data through the strait, any repricing in the crude options skew, and whether the threat is echoed at the political level or confined to the IRGC.
