Strait of Hormuz Shipping News — Live Disruption Tracker
The Strait of Hormuz is the world's most important oil chokepoint — ~20% of global seaborne crude and 30% of LNG transit through 21 nautical miles between Iran and Oman. We track every incident, harassment, closure threat and insurance impact.
What flows through the Strait
- 17–20 million barrels per day of crude and condensate (~20% of global seaborne)
- ~30% of global LNG (mostly Qatari)
- Saudi, Iraqi, Kuwaiti, UAE, Bahraini and Qatari exports — no pipeline alternative for most volume
- Inbound: refined products, machinery, container traffic to GCC ports
Historical disruption events
- 1980s 'Tanker War' (Iran-Iraq): 411 ships attacked, 60 lost. Brent spiked but US Navy reflagging mitigated.
- 2019 Limpet mine attacks: Six tankers damaged. Brent +$2 in 24h; insurance premiums tripled.
- 2023 IRGC tanker seizure (Advantage Sweet): Brent +$1 in 4h; insurance market repriced sustained Hormuz risk.
- 2025–2026 ongoing IRGC harassment of tankers: Multiple boardings, GPS jamming, harassment of US Navy CTG transits. Cumulative pricing effect: ~$3–$5 of permanent Brent risk premium.
How a closure would impact markets
A full Strait closure (even temporary, days-long) would remove ~17 million barrels per day from global supply. Even with SPR releases and OPEC reserve capacity, that gap can't be closed. Models suggest Brent +$30–$50 within 48h and sustained $80+ pricing through the closure.
This is why even a tactical IRGC seizure of one tanker can move Brent $2–$5 — the option-implied probability of a strategic closure rises.

FAQ
Where is the Strait of Hormuz?
Between the Persian Gulf and the Gulf of Oman, separating Iran (north) from the UAE Musandam peninsula (south). The narrowest point is approximately 21 nautical miles wide; the international shipping lanes are roughly 2 nautical miles wide each direction.
Why is the Strait of Hormuz important for oil prices?
About 17–20 million barrels per day of seaborne crude transit the Strait — roughly 20% of global oil consumption. There is no full pipeline bypass for most of that volume, so any sustained disruption directly removes supply from the market.
Has the Strait ever been closed?
Not fully. During the 1980s Tanker War, Iran and Iraq attacked shipping but never closed it. Modern threats include limpet mines (2019), tanker seizures (multiple incidents 2019–2026), GPS jamming, and IRGC harassment of US Navy escorts. The threat itself moves markets even without actual closure.
Does Saudi Arabia have a bypass?
Yes — the East-West Pipeline (Petroline) can move ~5 million barrels per day from Eastern Province to Yanbu on the Red Sea, bypassing the Strait. However it's only enough for Saudi exports. UAE has a smaller 1.5M bpd bypass to Fujairah. Iraq, Kuwait, Qatar and Bahrain have no bypass.
