Protracted Low-Intensity Naval and Missile Standoff Locks Strait of Hormuz into Semi-Blockade
Theater: Strait of Hormuz

Moderate confidence (60%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over the next 30 days, absent decisive diplomacy, the U.S.–Iran confrontation is likely to solidify into a protracted low-intensity standoff featuring intermittent missile launches, drone overflights, and episodic harassment of tankers, effectively creating a semi-blockade of Hormuz. Shipping volumes may remain dramatically reduced versus peacetime, with only escorted or high-premium vessels transiting, while both sides avoid sinking ships or striking mainland population centers. This would redraw global energy logistics, shift flows toward non-Gulf sources, and keep insurance and freight markets in a sustained crisis posture. Confirmation would be persistently depressed transit counts, repeated minor incidents, and continued military alerts; denial would be either a negotiated de-escalation with normalized traffic or a sharp escalation into open blockade or war.
