Hormuz traffic slows to multi-week low as renewed US, Iran strikes raise safety risk  Reuters U.S. insists Strait of Hormuz remains open despite Iran’s declaring it closed as strikes escalate  NBC News July 11, 2026 — US strikes Iran after ship attack in Strait of Hormuz  CNN Iran war updates: IRGC navy declares Strait of Hormuz closed  Al Jazeera Hormuz Route Open Despite Iran Declaration, Maritime Group Says  Bloomberg.com

What it means

The IRGC's formal declaration of the Strait of Hormuz as closed — even as maritime groups report traffic continues — is a genuine escalation beyond the prior 'closure risk' framing and has historically been associated with an incremental spike in crude prices, gains in defense stocks, and pressure on airline shares from higher jet-fuel costs. The US insisting the strait remains open adds uncertainty but does not remove the risk premium. The crude and dollar moves already called in prior signals partially reflect this situation, so the marginal new move in crude may be smaller than an initial shock would imply.

  IRGC formally declaring the Strait closed — even while traffic continues — marks a genuine escalation beyond the prior 'closure risk' framing; a formal declaration by the Iranian navy is a new, harder threat that adds incremental supply-risk premium above what was already called
