IRGC spokesperson says that the Strait of Hormuz is completely closed and we will not allow passage.

Threats to close the Strait of Hormuz are a recurring feature of Iranian escalation cycles, and historically the signal has mattered more as rhetoric than as execution: a full closure has never been sustained even during the most acute prior confrontations, because it would sever Iran's own export lifeline and invite a military response from the US and Gulf states whose naval presence in the region is built precisely around keeping the strait open. A large share of global seaborne crude transits this chokepoint, so the established market pattern is an immediate risk premium in Brent and front-month WTI, steepening of prompt spreads, and a bid in tanker rates and war-risk insurance, with the move fading quickly if no physical disruption follows. The distinction worth drawing is between declared closure and enforced closure: harassment of individual tankers, seizures, or mine threats have historically been enough to move freight and insurance costs, while verified interruption of actual flows is what sustains a crude repricing. The IRGC spokesperson is a familiar channel for maximalist messaging, so attribution of intent carries less weight than observable follow-through. Worth watching are tanker tracking data, insurance quotes for Gulf transits, any US naval advisory, and whether Gulf producers activate alternative pipeline routes that bypass the strait.
