Treasury Targets Ecuador Cocaine Network Using Fishing Businesses

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has sanctioned 15 Ecuador-based individuals and entities and blocked 10 vessels allegedly involved in moving thousands of kilograms of cocaine each month from South America to Mexico. The action targets networks linked to Ecuadorian gangs Los Choneros and Los Lobos, as well as Mexican cartels including the Sinaloa Cartel and Cartel de Jalisco Nueva Generación (CJNG).

Key takeaways for compliance professionals:

• Legitimate businesses can conceal high-risk networks
  OFAC identified fishing companies and vessels allegedly used to provide fuel, food, medical support and logistical assistance to cocaine-laden vessels. This highlights the need to assess business activity alongside ownership and transaction patterns.
• Sanctions exposure increasingly extends across connected entities
  The action targets not only individuals but also companies, vessels and related commercial structures. OFAC’s designations demonstrate how sanctions enforcement can reach supporting infrastructure surrounding a criminal network.
• Beneficial ownership and relationship screening remain critical
  Several sanctioned companies were identified as owned or controlled by designated individuals. Financial institutions therefore need screening processes that identify indirect ownership and connections rather than relying solely on direct name matches.

OFAC targets cocaine trafficking infrastructure

According to Treasury, the network operated fishing vessels near Manta, Ecuador, using legitimate commercial activity as cover while transferring cocaine to small “go-fast” vessels travelling north through the Eastern Pacific Ocean toward Mexico.

The operation allegedly supported trafficking networks associated with Los Choneros, Los Lobos and Mexican cartels. OFAC’s action included fishing businesses, construction-material companies and vessels accused of providing logistical support to the trafficking operation.

The designations form part of the broader U.S. effort to disrupt cocaine trafficking through the Eastern Pacific. Treasury said the action was coordinated with multiple U.S. law enforcement and military agencies and builds on Operation Pacific Viper, launched by the U.S. Coast Guard in August 2025.

As of June 2026, the operation had seized more than 225,000 pounds of cocaine in the Eastern Pacific, according to Treasury.

Compliance implications

For financial institutions, the case reinforces why sanctions screening cannot be limited to checking customer names against sanctions lists. Ownership structures, related companies, vessels, business activities and connections between counterparties can all become relevant when assessing sanctions exposure.

Under OFAC rules, property and interests in property belonging to designated persons are blocked when subject to U.S. jurisdiction. Entities owned 50% or more, directly or indirectly, by blocked persons are also subject to blocking requirements.

The action therefore provides another reminder that effective sanctions controls require visibility into ownership, control and commercial relationships, particularly in sectors vulnerable to criminal exploitation.

Compliance takeaway: Sanctions risk can sit behind an apparently legitimate business. Firms with exposure to Latin American trade, maritime activity, or correspondent relationships should ensure that their screening and enhanced due diligence processes can identify indirect ownership, connected entities, and network-level risk.
