**Summary**: Three Liberian‑flagged oil tankers were struck by unidentified projectiles while transiting the Strait of Hormuz, after reportedly switching off AIS and engaging in ship‑to‑ship transfers with Iranian and Venezuelan crude. This directly elevates physical supply risk and the regional risk premium for Middle East exports, with immediate upside pressure on crude benchmarks and tanker insurance rates.

## Detail

Reports indicate three Liberian‑flagged oil tankers — Al Ruwais, Mersin Prosperity and Sinbad — were hit by unknown projectiles while crossing the Strait of Hormuz. Shipping intelligence (Marisks) notes the vessels had disabled their tracking transponders and that two had recently performed ship‑to‑ship transfers involving Iranian and Venezuelan crude. A separate wire headline (Reuters‑cited) corroborates that three Liberian‑flagged oil tankers were struck by unidentified projectiles in the strait.

This is a direct security event in one of the world’s most critical oil chokepoints, handling roughly 30% of seaborne crude and large volumes of refined products and condensate. Even without confirmation of casualties, spills, or long‑term damage, deliberate attacks on multiple tankers materially increase perceived transit risk. Insurers are likely to raise war‑risk premia on Hormuz transits, and some owners may temporarily reroute or delay voyages while additional naval escorts or security guidance are assessed.

The short‑run physical supply impact is modest unless hull damage sidelines the vessels for long periods or prompts a broader halt, but the risk premium effect on prices is meaningful. Brent and Oman/Dubai complex should see immediate upside, particularly front‑month contracts, with a steeper backwardation if traders price higher near‑term disruption risk. Middle East sour grades, especially those loaded out of Gulf ports transiting Hormuz, are most exposed. Time charter rates and spot freight for LR2s and VLCCs in the region should also firm on higher insurance and perceived risk.

The detail that two vessels had been handling Iranian and Venezuelan crude adds a sanctions‑evasion and attribution layer. If this is interpreted as targeted action by a state or non‑state actor against sanctions‑linked flows, it could chill gray‑market movements of Iranian barrels, tightening already constrained supplies from that channel. Conversely, if Iran is blamed, markets will price an increased probability of US or regional retaliation, further boosting crude and gold on geopolitical risk.

Historical analogues include Houthi and limpet‑mine attacks on Gulf shipping in 2019 and 2023‑24, which generated 2–5% intraday moves in Brent and sustained a higher risk premium for weeks. Unless quickly clarified and contained, today’s incident has potential for a multi‑week structural risk premium in Middle East crude benchmarks and tanker markets.
