**Summary**: Maritime intelligence firm Marisk reports three Liberian‑flagged oil tankers were struck by projectiles while transiting the Strait of Hormuz, with two previously involved in sanctioned crude movements. This reinforces an escalating threat pattern against ‘dark fleet’ shipping in the chokepoint that handles ~20% of global seaborne oil, likely lifting crude and product risk premia and insurance costs, and potentially tightening effective supply if more tonnage avoids the route.

## Detail

1) What happened: Maritime intelligence firm Marisk reports that three Liberian‑flagged tankers – Al Ruwais, Mersin Prosperity and Sinbad – were hit by projectiles while crossing the Strait of Hormuz. The report notes that at least two of the vessels had recently carried sanctioned crude (implying Iranian/Russian flows or ship‑to‑ship blended barrels). This comes on top of existing reports this week of multiple ‘dark’ tankers being attacked in Hormuz, confirming a pattern rather than an isolated incident.

2) Supply‑side impact: Roughly 17–20 million bpd of crude and condensate plus large volumes of refined products transit Hormuz daily. At this stage there is no indication that the strait is physically blocked, but repeated strikes on tankers tied to sanctioned flows will have three key effects: (a) higher war‑risk insurance and freight for all Gulf exports, (b) some owners, especially in the grey/dark fleet, may temporarily halt or reroute shipments, effectively constraining Iranian exports and potentially some UAE/Qatar swaps, and (c) higher operational risk for ship‑to‑ship transfers and opacity‑based trades. Even a 200–400 kbpd disruption or delay to Iranian exports, or a 5–10% jump in Gulf freight, is enough to move flat price and spreads >1% in the short term.

3) Affected assets and direction: Brent and WTI should see an immediate risk‑premium bid, particularly in front‑month contracts and time spreads (bullish backwardation). Dubai/Oman benchmarks and Middle East OSPs are directly exposed. Clean products (gasoil, jet) may also firm on higher freight and insurance costs. Tanker equities and war‑risk insurers are in focus; Middle East sovereign CDS could widen marginally if the pattern escalates into broader Gulf shipping risk.

4) Historical precedent: Previous tanker attacks in 2019 and during the 2023–24 Red Sea/Hormuz disruptions triggered 2–5% intraday moves in crude benchmarks despite minimal sustained volume loss, with the price reaction driven largely by risk premium and logistics constraints.

5) Duration: If attacks remain narrowly focused on dark/sanctioned flows, the structural impact will be a persistent, higher risk premium on Iranian exports and Gulf transits and ongoing volatility, but not a long‑term physical shortage. A wider campaign affecting mainstream flag carriers or any sign of mines/closure threats would significantly raise the shock magnitude and duration.
