IRGC Says It Blocked 6 Ships From Passing Through Strait Of Hormuz
What it means
An actual IRGC interdiction of vessels — as opposed to threats or posturing — represents a genuine escalation beyond the existing Iran-US tension backdrop already priced in. Historically, confirmed physical blockages of the Strait of Hormuz have been associated with a fresh crude risk-premium spike and sharp increases in war-risk shipping insurance costs. The crude call was already in the prior chain, but the confirmed, operational nature of this act adds incremental upward pressure.
