The latest weekly data from the United Kingdom’s Maritime Trade Operations (UKMTO) shows an unprecedented spike in hostile incidents targeting commercial vessels near the Strait of Hormuz. Twelve ships reported attacks between 5 October and 11 October – the highest weekly total since the conflict between the United States, Israel and Iran began. This surge coincides with a measurable slowdown in oil shipments through the waterway.
Verified Events
Attack tally: The week saw six vessels struck on a single Sunday, a one‑day high, and four further reports later in the week. The previous week had recorded ten attacks, indicating a rising trend.
Notable incidents:
- The Nicaragua‑flagged tanker Petro Dolphin was set ablaze by a drone near Sohar Anchorage, Oman – more than 250 km from the strait. Eleven Indian seafarers were rescued, with two still missing.
- The container ship GFS Pride sank after an unknown projectile struck it inside the strait; all twenty‑one crew members were evacuated safely.
- Separate attacks on tankers north of Qatar and near the UAE town of Al‑Jazirah al‑Hamra extended the threat zone well beyond the strait itself.
Iran’s Islamic Revolutionary Guard Corps (IRGC) released footage of the sinking GFS Pride, claiming the vessel was carrying “2,500 containers of contraband” and had taken an “unauthorised route”.
Impact on Oil Transit
Data from trade‑intelligence firm Kpler indicates that oil throughput on 13 October was about 12.6 million barrels per day, down from 15 million barrels per day at the end of September and well below the pre‑war baseline of roughly 17 million barrels per day. The slowdown follows the record‑high attack count, suggesting that heightened risk is curbing commercial traffic.
US Central Command, which oversees Middle‑East operations, posted that “commercial traffic continues to flow through the Strait of Hormuz with coordinated protection from US forces and regional partners,” underscoring the continued presence of naval escorts despite the attacks.
Assisted transits – where US‑led naval forces help vessels navigate the strait – rose by 85 %** compared with the same period in August, according to US Navy data. This increase reflects the growing reliance on protective convoys as the threat environment intensifies.
Analysis and Uncertainty
Analysis: Experts cited in the report argue that Iran is expanding its maritime campaign to deter ships from using the “shuttle” route along Oman's coast, which it deems “unauthorised”. Martin Kelly, CEO of Orbital Risk Intelligence, said Iran has “evolved its strategy” and is conducting “near daily or multiple attacks every single day” to “stop the ships going through and to deter others”.
Uncertainty: While the data confirms a record number of attacks and a concurrent dip in oil flows, the precise causal link between the two remains difficult to quantify. The report notes that some incident dates are approximated, and the full extent of cargo losses or longer‑term disruptions to global oil markets is not yet clear.
What This Means for Stakeholders
- Shipping companies may need to reassess route planning and increase reliance on escorted transits, potentially raising operational costs.
- Oil exporters could face reduced volumes through the strait, prompting a shift to alternative shipping lanes or increased storage strategies.
- Policy makers must weigh the security benefits of naval escorts against the risk of escalation in a volatile region.
As attacks continue to spread beyond the immediate vicinity of Hormuz, the maritime community watches closely for any further escalation that could reshape global energy logistics.
