Sustained dual blockade forces energy markets to price in permanent Hormuz friction — not just elevated risk. If shippers reroute around the Cape and through the Pacific, the First Island Chain (where 1,300 Marines with anti-ship missiles just deployed in the Philippines per April 25 signals) becomes the new choke point for energy flows to Japan and South Korea.
This converts the Indo-Pacific containment play from a contingency into an active leverage mechanism over allied energy security.
This is no longer signaling escalation — it's the escalation.
The U.S. blockade announced April 24 (lethal force authorized globally) is now operationalized against merchant traffic in real time, while Iran responds with its own seizures. One week of dual interdictions proves this isn't rhetorical: insurance costs spike, routing delays compound, and shippers begin diverting around the region entirely.
The jet fuel diversion already underway (235,000 barrels rerouted to Subic Bay via the Pacific) will become standard practice if this holds. This breaks the assumption that a ceasefire — even one Trump extended April 21 — creates a return to normal commerce. It doesn't. The blockade enforcement is the new normal.
How many total transits through Hormuz have been blocked or delayed in the past week, and what percentage of daily traffic does that represent? The article cites six interdictions but doesn't establish whether this is a trickle or a choke point.
