Iran halts oil flow through Strait of Hormuz, disrupting 20% of global supply

At least 13 oil tankers turned back from the Strait of Hormuz after Iranian warnings, interrupting approximately 20% of global oil flow. The complete transit stoppage has pushed odds lower on the Strait of Hormuz traffic normalization market, with a 35% expected move priced in as traders bet against a quick resolution.

The halt cuts off roughly 15 million barrels of oil per day. The US Navy’s blockade and Iranian retaliations have compounded the disruption. While specific current odds on the normalization market are not available, the complete stoppage has driven sharp selling on YES positions.

The US escorts through Hormuz by April 30 market sits at 19% YES, relatively unchanged. A recent 4-point spike appears driven by speculative trades rather than new information. The transit halt doesn’t directly affect this market since US Navy escort plans weren’t addressed in the latest escalation.

Zero transits is a different category of event than reduced traffic. Traders now have to price in the possibility of a prolonged blockade against any diplomatic resolution. There are no alternative routes that can absorb 15 million barrels per day of displaced oil flow, which puts direct pressure on diplomatic channels to produce results.

Watch for statements from the IRGC or the U.S. Department of Defense. Any signal of easing controls or a change in military posture could move both markets. The next catalyst is likely either a high-level diplomatic engagement or a decisive military action.
