Maritime & Chokepoints

Strait of Hormuz

The Strait of Hormuz is the Gulf exit chokepoint for about 20% of seaborne crude oil.

The Strait of Hormuz is the narrow waterway connecting the Persian Gulf to the Gulf of Oman and the open ocean. It is the single most closely watched energy chokepoint on Earth because about 20% of the world’s seaborne crude oil — and a large share of liquefied natural gas — has no alternative route out of the Gulf.

In WorldMonitor, Hormuz is one of the chokepoints with live flow estimates: vessel activity, congestion, and disruption signals are correlated against energy markets so an operator can see whether a Gulf tension event has a plausible transmission path into oil and gas prices.

Maritime Chokepoint

A maritime chokepoint is a narrow passage through which a large share of global trade, energy, food, or military movement must pass.

Automatic Identification SystemAIS

AIS (Automatic Identification System) is the transponder standard that broadcasts a ship’s identity, position, and course for tracking vessel traffic through chokepoints.

Chokepoint Congestion

Chokepoint congestion is an above-normal build-up of vessel traffic waiting to transit a strait or canal, detected from AIS as an early disruption sign.
