Shrinking Traffic in the Strait of Hormuz: The Tipping Point for Global Oil Flows

Amid heightened Iran‑U.S. tensions, 84 vessels traversed the Strait of Hormuz, a stark decline from 900+ ships in the same period last year.

War Shadows Over the Strait

■Vessel traffic fell by ~90% during the cease‑fire window of Feb 28–Apr 7.

■The July 6‑7 resurgence of attacks prompted JMIC to label the threat "severe."

■The U.S. announced permission for 70 ships, all of which disabled AIS transmissions.

Who Sails Under Which Flag?

■9 Iranian and 2 Pakistani ships sail under their national flags.

■73 vessels display a flag different from their owners, obscuring true ownership.

■13 UAE‑registered cargo ships, 2 LPG tankers and 3 support vessels continued to use the strait to sustain regional energy flows.

Pipelines: Limits of the Alternative Route

■The UAE‑ADCOP and Saudi‑Petroline pipelines together provide 4 million barrels per day of alternative capacity.

■Compared with the normal 15 million barrels per day flow, they cover only about 25% of the shortfall.

■The Bab al‑Mandeb Strait faces rising piracy and Houthi attacks, threatening to become a new chokepoint.

Economic Calculus: The Price of Risk

■Vortexa economist David Wech notes that transiting the strait preserves 90‑100% of revenue, whereas halting production would erode margins.

■Kpler analyst Matt Smith emphasizes barrel prices above $80, translating into multi‑million‑dollar incremental earnings.

■Brent rebounded after July's intensified clashes, injecting volatility into global energy markets.

Analyst Insight (Ufuk Tepe): The Strait of Hormuz remains a strategic bottleneck. Alternative pipeline capacity is insufficient to dampen short‑term price spikes. Investors must embed geopolitical risk into risk‑reward models, revisiting cash‑flow forecasts for energy firms. Lack of transparency in fleet registries—particularly for Greek, Indian, and Chinese operators—questions AIS data reliability, potentially inflating premiums on near‑term oil futures and straining derivative market liquidity.
