Hormuz Oil Flows Creep Higher as More Supertankers Exit

Why It Matters

Even a slight easing of Hormuz traffic hints at potential supply‑side relief, but the continued blockage sustains tight oil markets and underscores the geopolitical leverage of Iran and the United States over global energy flows.

Key Takeaways

• Four supertankers exited Hormuz, adding ~2 million barrels daily.
• Pre‑war traffic averaged ~20 tankers per day, now far lower.
• Blockade cuts about 1 billion barrels from global oil supply.
• Iran now permits Chinese VLCCs, reflecting diplomatic shifts.
• Traders say increased flows unlikely to shift market balance.

Pulse Analysis

The Strait of Hormuz has long been a chokepoint for crude oil, and its near‑total closure since the February conflict has removed roughly one‑billion barrels from the world’s supply chain. That disruption has kept benchmark prices elevated and forced refiners to seek alternative routes, often at higher freight costs. Understanding the scale of the blockage is essential for investors tracking inventory builds, OPEC production decisions, and the risk premium baked into oil futures.

Recent vessel‑tracking data shows four supertankers—each a very large crude carrier—have left Hormuz since May 10, collectively moving about 2 million barrels per day. While this marks a measurable uptick, it remains a fraction of the pre‑war flow of around 20 tankers daily. Notably, three of the departing VLCCs were loaded with Iraqi crude, and the fourth carried cargoes from the UAE and Kuwait. Iran’s decision to allow Chinese ships, such as the Yuan Hua Hu, to pass reflects a strategic pivot toward Beijing amid ongoing U.S. sanctions, adding a diplomatic layer to the logistical challenges.

Looking ahead, analysts caution that the modest increase is unlikely to alter the market’s tightness. The risk of vessels disabling transponders to avoid detection suggests that actual traffic could be higher, but the willingness of owners to re‑enter a contested waterway remains low. Until a durable diplomatic solution emerges or the U.S. blockade eases, the Hormuz bottleneck will continue to act as a price‑supporting factor, influencing everything from refinery margins to the valuation of energy‑linked equities.
