Strait of Hormuz
The only sea route out of the Persian Gulf, and the single most concentrated point of failure in world energy trade. Everything loaded at Ras Tanura, Kharg Island, Basra or Ras Laffan leaves through a channel whose shipping lanes are roughly two miles wide in each direction.
How much moves through it
20.7 million b/d in 2024 and 21.8 million b/d in 2023 — the figure moves year to year.
Equivalent to roughly 20% of global petroleum liquids consumption.
11.4 Bcf/d. Qatari volumes have no pipeline alternative to Asian and European buyers.
What a disruption here moves
Standing structural relationships, not forecasts. We name the direction and the mechanism, and link the published index where you read the current value — we do not quote a number we cannot cite.
Gulf transits are priced per voyage as a percentage of hull value. When the Lloyd's Joint War Committee revises its listed areas, every subsequent transit reprices immediately — this moves faster than any freight index.

Owners withdraw tonnage from a contested strait before charterers renegotiate, so available tanker supply tightens ahead of the rate move rather than after it.

More than a quarter of seaborne oil trade leaves the Gulf through this strait and pipeline bypasses cover only a fraction of it, so a credible threat to transit has no volume-scale workaround.

Around a fifth of global LNG trade shares the same water, with no pipeline alternative from Qatar to Asian or European buyers.

Bunker fuel is refined from the crude that transits here, so a crude move reaches marine fuel and then carriers' fuel surcharges within weeks.

Cargo underwriters reprice or restrict cover for Gulf-loading voyages alongside the hull war-risk change, which lands on the cargo owner rather than the carrier.

How a problem here propagates
- There is no meaningful pipeline bypass for most Gulf crude. Saudi Arabia's East-West line to the Red Sea and the UAE's Habshan–Fujairah line together carry a fraction of what transits the strait, so a closure cannot be routed around at volume.
- Hull war-risk premiums for the Gulf are quoted per transit as a percentage of a ship's insured value. A listed-area change by the Lloyd's Joint War Committee reprices every subsequent voyage immediately — faster than any freight index reacts.
- Owners withdraw tonnage from a genuinely contested strait before rates are renegotiated, so available tanker supply tightens ahead of, not after, the quoted rate move.
- Because a fifth of LNG trade shares the same water, energy shocks here hit gas and oil benchmarks together rather than in sequence.
The detours that actually exist
- Saudi East-West Pipeline to Yanbu on the Red Sea — partial relief for Saudi barrels only.
- UAE Habshan–Fujairah pipeline, bypassing the strait for a portion of Abu Dhabi's exports.
