Summary
The Islamic Revolutionary Guard Corps (IRGC) has issued a directive to shipowners to follow Iranian recommendations, effectively threatening to close the Strait of Hormuz until a US naval blockade is lifted. This represents a significant escalation in economic warfare, targeting global energy supply chains as a leverage point against US military pressure in the region. The threat of closing this critical chokepoint could trigger immediate global market volatility and force a direct US-Iran confrontation.

"The NEW EVENT explicitly cites the 'US naval blockade' as the condition for the Strait of Hormuz closure.
