Maritime Sanctions Expand: 1,966 Vessels Sanctioned by August 2026
The trading history of August’s newly sanctioned vessel cohort remains heavily connected with Iran and Russia. Through August 2026, these vessels handled approximately 27.4 MMbbl of liquid exports. Iran was the largest identified origin at approximately 10.7 MMbbl, followed by Russia at 6.5 MMbbl. The United Arab Emirates and Saudi Arabia each accounted for approximately 1.6 MMbbl, while Kuwait contributed around 0.8 MMbbl and the United States around 0.7 MMbbl. Approximately 5.5 MMbbl fell within the aggregated “Others” category.
Iran and Russia therefore account for approximately 63% of identified 2026 origin volumes. The concentration is notable given the regulatory actions behind the August cohort: the UK additions were explicitly aimed at Russia’s shadow fleet, while the largest US action targeted vessels and companies facilitating Iranian petroleum exports.
Destination Profile Reveals Asian Markets
China is the largest destination for the August cohort in 2026, receiving approximately 14.8 MMbbl, or 54% of recorded liquid flows. India follows at approximately 6.3 MMbbl, representing another 23%. Singapore accounts for approximately 2.6 MMbbl, while the aggregated “Others” category represents around 1.6 MMbbl.
China and India together therefore account for approximately 77% of the identified destination volumes. The concentration is consistent with the broader movement of higher-risk Iranian and Russian barrels towards a smaller group of Asian markets, while the presence of Singapore within the destination profile also highlights the continuing importance of regional trading and transshipment hubs.
Commodity Profile Dominated by Crude Oil
Crude oil dominates the commodity profile even more clearly than in July. Approximately 24.3 MMbbl of the 27.4 MMbbl handled by the August cohort in 2026 was crude, equivalent to almost 89% of the total. Fuel-oil-related grades account for most of the remaining volumes, including approximately 0.9 MMbbl of FO, 0.8 MMbbl of SRFO, 0.8 MMbbl of dirty feedstocks and 0.7 MMbbl of other fuel oils.
The product composition closely matches the regulatory focus of the month. Despite the inclusion of two fishing vessels in the overall sanctions additions, the commercially active tanker cohort remains overwhelmingly connected with crude oil and petroleum products.
Sanctioned Vessels Reach 1,966 by August
The cumulative number of sanctioned vessels reached 1,966 by the end of August. The addition of 14 vessels represents month-on-month growth of approximately 0.7%, a substantial slowdown from the 57 additions recorded in July.
The lower number does not indicate an equivalent reduction in regulatory significance. August included a formal expansion of US Iran sanctions authority into the shipping sector, meaning that the policy perimeter widened even as the number of individual vessel additions declined.
Sanctioned companies reached 876 at the end of August, increasing by seven during the month, or approximately 0.8%. This compares with 31 additions in July, 28 in June and 30 in May.
All seven first-time company additions captured in the August dataset were associated with the 24 August OFAC action against Iranian shipping and oil-trading networks. The pattern reinforces the connection between vessel sanctions and the companies legally owning, operating or facilitating their activity.
Flag Categories Reflect Regulatory Focus
Russia remains the largest flag category within the leading registries, reaching 533 sanctioned vessels by the end of August. Iran follows with 197, while China accounts for 135 and Cameroon for 108. Sierra Leone remains at 89, followed by Panama at 63, Comoros at 55 and Guyana at 48.
The August increase among the largest flag categories was relatively limited. Russia increased by five vessels, reflecting the UK’s shadow-fleet package, while Cameroon increased by one. Other newly sanctioned vessels were spread across registries including Palau, Gambia, Vanuatu and Barbados, while two of the fishing vessels entering the IMO dataset did not have a corresponding flag value within the source data.
The spread again demonstrates the limitations of relying solely on flag-state information in understanding the scope and complexity of maritime sanctions.
