Mexico’s illicit fuel trade: What does the latest US crackdown reveal about cartel risk in legitimate supply chains?

Introduction

On June 30, 2026, the US Treasury escalated its campaign against the Cartel de Jalisco Nueva Generación (CJNG), sanctioning two Mexican citizens and nine entities allegedly linked to a cross-border fuel-smuggling and tax evasion network. The designations focused on individuals and companies accused of facilitating the movement, storage and sale of illicit fuel and the financial flows that sustain the scheme. 

The Financial Crimes Enforcement Network (FinCEN) also issued an alert outlining the financial and commercial patterns associated with fuel smuggling by Mexico-based criminal organisations, including typologies, red flags and expectations for suspicious activity reporting.

This coordinated action points to a more collaborative and expansive regulatory approach. 

US authorities are not only identifying key criminal actors but also mapping the wider ecosystem of intermediaries, logistics providers and commercial entities that enable illicit revenue generation. For financial institutions and corporates alike, the focus is shifting toward understanding how seemingly legitimate business activities can intersect with criminal networks.

Cartel risk inside legitimate commercial networks

Fuel theft and smuggling - widely known in Mexico as huachicol - have become “the most significant non-drug illicit revenue source for the Cartels,” according to FinCEN. US authorities have described highly organised, cross-border schemes often involving US fuel suppliers, Mexican trading companies, false or misleading customs documentation, freight and logistics providers, shell companies, storage facilities, retail gas stations and cross-border payments.

The latest action illustrates how organised crime can operate through and alongside legitimate commercial ecosystems. US Treasury describes fuel being diverted through “interconnected networks of US and Mexican front and shell companies” spanning freight, logistics and other industries. OFAC’s targets include businesses in transportation, financial services and real estate, while FinCEN’s alert describes risks involving oil and gas companies, freight and logistics businesses, importers and financial channels. Some actors may be complicit; others may be exploited or exposed without understanding the full network around a transaction.

Crucially, FinCEN explicitly points to due diligence measures such as requesting export documentation and verifying whether counterparties hold the relevant permits to import fuel into Mexico.

The risk has evolved beyond sanctions exposure. It is now a supply-chain and commercial due diligence story.

Why sanctions screening is not enough

Traditional sanctions screening simply asks: is a counterparty or owner a designated person? 

The latest action points to a more complex question: does the wider commercial network make sense?

At first glance, a company can appear entirely legitimate and pass initial checks. It can be incorporated, operational and absent from sanctions lists. It may even hold a valid regulatory permit. However, its role in a transaction may not align with its authorisations, operational footprint or financial activity. 

FinCEN’s alert highlights, among other indicators, Mexican counterparties lacking the relevant permits to import fuel; small US oil and gas, freight or logistics companies whose transaction volumes or profit margins appear inconsistent with their profiles; payments involving unrelated third parties or pass-through entities; and businesses whose claimed cross-border operations do not align with their visible corporate footprint. FinCEN also points to the use of international wires and digital assets in relevant schemes.

These risks are unlikely to be identified through sanctions screening alone. They require companies to connect ownership, permits, commercial relationships, transaction patterns and operational reality.

As regulators intensify their focus on trade-based money-laundering and complex commercial networks, the challenge is no longer screening for sanctioned names after a network has been exposed – it is mapping the relationships behind those networks before they become enforcement cases.

From cartel footprint to commercial exposure

Risk Advisory’s FTO-Cartel Risk Tracker helps organisations identify where designated criminal groups create geographic and sectoral exposure. The latest fuel-smuggling actions show how that risk can travel beyond a cartel’s immediate territorial footprint and enter legitimate commercial networks through supply chains, corporate structures, intermediaries and payment flows.

For investors and companies, this raises practical questions: 

Does an acquisition target’s growth make sense given its infrastructure? 

Do its permits cover the activities it actually performs?

Who sits behind its key suppliers and customers?

Are payments coming from the contractual counterparty? 

Do transport routes and trading volumes align with the stated business model?

At Risk Advisory, we support clients in strengthening financial crime frameworks through intelligence-led risk assessments, enhanced due diligence, supply chain investigations and financial crime advisory. As criminal networks become increasingly embedded within legitimate commercial activity, organisations need controls that connect customer behaviour, transactions and commercial context-not simply compliance against sanctions lists.
