Shipping through the Strait of Hormuz slows to near standstill after multiple ADNOC tanker attacks and rising US‑Iran tensions
Question
Shipping through the Strait of Hormuz slows to near standstill after multiple ADNOC tanker attacks and rising US‑Iran tensions
Direct answer
Near‑halted Hormuz traffic disrupts Gulf crude and LPG flows, lifts war‑risk premiums and insurance rates, and supports higher spot and forward shipping and energy prices while stranding tonnage.

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ1 | reduced physical flows through a chokepoint that previously carried about a fifth of global traded oil tighten supply expectations and support Brent spreads | Upintraday | Reports tie oil’s >2% gain and Brent above $90–91 per barrel to tanker attacks and sharply lower vessel transits through Hormuz, with shipping ‘grinding to a near standstill’ |
| CL1 | US benchmark prices incorporate higher disruption risk from attacks on ADNOC tankers and curtailed flows | Up1-5d | WTI futures climbed around 2.5–3% to the mid‑$84–85 range in response to Middle East tensions and shipping slowdown at Hormuz |
| ADNOCLNG | operator of attacked vessels faces higher insurance, operational risk and potential revenue disruption from constrained exports | Down1-4w | UAE statements and analysis highlight repeated attacks on ADNOC‑linked tankers and associated disruption in the strait |
| WARRISK_INS | insurers reprice war‑risk cover as tanker attacks and near‑zero passage dramatically raise expected loss probabilities | Up1-3m | Sector commentary notes war‑risk premiums around Hormuz have surged many times above normal as attacks and stalled traffic leave hundreds of vessels stranded |
| TNK | global tanker owners benefit from sharply higher spot rates as war‑risk premiums and rerouting tighten effective supply of safe tonnage | Up1-4w | Shipping analyses describe traffic dropping to ~1% of pre‑crisis levels and insurance costs spiking, dynamics historically associated with elevated tanker earnings |
