Negligible.

US banks are aiding the cartels. Treasury weighed those American banks, acknowledged they existed, and described the risk of naming them with one word: negligible.

By Matt Stone

Mexican criminal organizations—especially the Sinaloa Cartel and CJNG—now dominate the U.S. illicit drug landscape, producing nearly all the fentanyl entering the country and driving what has become the leading cause of death for Americans aged 18 to 45. Their reach is amplified by sprawling distribution networks that rely on multi‑city supply chains, local gangs, and individual dealers, all coordinated through encrypted apps and social media platforms that enable operations in every region. Behind the scenes, these cartels move billions through sophisticated financial pipelines that include Chinese money‑laundering networks, cryptocurrency channels, shell companies, and complicit actors within both U.S. and Mexican banking systems, allowing illicit proceeds to circulate with remarkable speed and anonymity.

According to the most recent DEA threat assessments, Mexican cartel activity—specifically from the Sinaloa Cartel and the Jalisco New Generation Cartel (CJNG)—is now present in all 50 U.S. states.

The cartel’s money could not stay in pesos. To pay the Chinese chemical companies that ship the ingredients for fentanyl, the cash skimmed off American streets had to become American dollars, and there is only one way for a Mexican bank to turn pesos into dollars: it has to pass them through an American bank.

There is one version of this story that gets written from anonymous sources and unprovable assertions, a roster of banks and politicians and federal agents secretly on a cartel payroll, names dropped with the confidence of someone who will never have to defend them in front of a judge. That version is easy to write and worthless. It collapses the moment anyone asks for the evidence.

This is the other version. Every name here comes from an unsealed federal indictment, a Treasury sanctions designation, or a recorded conviction. Where the record supports a name, the name appears. Where it doesn’t, this account says so, because the gap between what is true and what is provable is itself the story.

And the gap is the story. Because once you hold the documented record up to the light, the most striking thing is not the length of the list. It is the shape of the silence around it.

Last summer, the Treasury Department sanctioned three Mexican institutions for laundering fentanyl money through the U.S. financial system. The orders run seven pages each. They name the Mexican banks, the cartels, the chemical brokers, the dollar amounts. They do not name a single one of the American banks that turned the pesos into dollars. Treasury weighed those American banks, acknowledged they existed, and described the risk of naming them with one word: negligible.

About 300,000 Americans have died from fentanyl-involved overdoses in the past five years, based on CDC mortality data. The CDC’s provisional and final overdose reports show that fentanyl‑involved deaths have remained extremely high each year, with annual totals generally ranging from ~55,000 to ~75,000 deaths per year between 2019 and 2024. Negligible.

The Thing the Silence Is About

The Sinaloa Cartel does not move multi-ton quantities of fentanyl, methamphetamine, and cocaine into the United States on logistics alone. Federal prosecutors say so themselves, repeatedly, in their own filings. The cartel functions because people in positions of trust let it function, and a certain number of those people carry badges and government credentials.

The U.S. Attorney who brought the largest corruption case to date put it without hedging: drug trafficking organizations like the Sinaloa Cartel would not operate as freely or successfully without corrupt politicians and law enforcement officials on their payroll. The DEA Administrator framed the same case as proof that the cartel relies on corruption and bribery to drive violence and profit, in a deliberate effort to undermine public institutions and put American lives at risk.

That is the government’s own theory of the case. Corruption is not a side effect of the trafficking. It is load-bearing. So the obvious question is the one nobody in an official capacity volunteers an answer to: how much of that corrupt infrastructure sits on the American side of the line?

The honest answer, based on what has actually been charged, is uncomfortable in both directions. The documented corruption is overwhelmingly Mexican. The American cases that exist are real, repeated, and almost entirely confined to one job title at one chokepoint. That pattern tells us something, and it is not reassuring.

What the Cartel Legally Is Now

The ground shifted in early 2025. On January 20, 2025, Executive Order 14157 directed the designation of cartels as terrorist organizations, and on February 20, 2025, the State Department designated eight organizations as Foreign Terrorist Organizations and Specially Designated Global Terrorists. The Sinaloa Cartel was on the list.

This is not a symbolic relabeling. Under 18 U.S.C. 2339B, knowingly providing material support to a designated Foreign Terrorist Organization is a federal crime, which extends criminal exposure far beyond the old drug-and-money-laundering framework, reaching anyone, any institution, any professional who knowingly helps the organization in any material way. The cartel was not new to sanctions when this happened. Over the years, OFAC has sanctioned more than 600 Sinaloa Cartel-linked individuals and companies under the Kingpin Act and Executive Order 14059. The FTO designation simply armed prosecutors with a heavier weapon.

That is important because it changes who can be charged for what. A bank that processes the wrong transactions, a chemical broker who looks away, a professional who launders the proceeds: under the new framework, the legal theory reaching them is no longer only narcotics law. It is terrorism law.

The Documented Corruption, Named

The single largest charged corruption case to date is Mexican. In late April 2026, the U.S. Attorney’s Office for the Southern District of New York and the DEA unsealed an indictment charging Ruben Rocha Moya, Enrique Inzunza Cazarez, Enrique Diaz Vega, Damaso Castro Zaavedra, Marco Antonio Almanza Aviles, Alberto Jorge Contreras Nunez, Gerardo Merida Sanchez, Jose Antonio Dionisio Hipolito, Juan de Dios Gamez Mendivil, and Juan Valenzuela Millan with drug trafficking and related weapons offenses. All are current or former high-ranking government and law enforcement officials in the Mexican state of Sinaloa, including the sitting governor, Ruben Rocha Moya.

The mechanics described in the indictment are the mechanics of institutional capture. Prosecutors allege the officials tipped off traffickers to investigations, prevented arrests, allowed violence to unfold unchecked, and directed state and local police units to safeguard drug loads as they moved toward the United States. One defendant carries the weight of the case’s darkest allegation: former Culiacan police commander Juan Valenzuela Millan faces additional charges tied to the 2023 kidnapping and killing of a DEA confidential source and the source’s relative.

The precedent for prosecuting that kind of corruption at the highest level is Genaro Garcia Luna. Garcia Luna, Mexico’s Secretary of Public Security from 2006 to 2012 and once the highest-ranking law enforcement official in the country, was convicted by a federal jury in Brooklyn of engaging in a continuing criminal enterprise, international cocaine distribution conspiracy, and related counts. The detail that lingers is the delivery method. Prosecutors alleged the cartel personally delivered bribe payments to him in briefcases containing millions of dollars, and that between 2002 and 2007 he aided at least six cocaine shipments totaling more than 50,000 kilos.

Both cases are Mexican officials. Hold that thought.

The American Side: One Job, One Chokepoint, Over and Over

When you go looking for charged American officials, you do not find senators or federal agency heads or bank executives in the dock. You find border officers. The same job, the same chokepoint, the same scheme, repeated across years and districts until the repetition itself becomes the finding.

The most fully litigated recent case is Leonard Darnell George. A federal jury found the former Customs and Border Protection officer guilty of receiving bribes by a public official, conspiracy to import controlled substances, and two counts of bringing in aliens for financial gain. The method was precise. Witnesses testified that George would notify members of a drug trafficking organization when he was at work and which lane he was on, and that they had one hour to reach his lane. The scheme cracked in February 2022 when a flagged vehicle entering his lane was forced to secondary inspection, revealing roughly 222 pounds of methamphetamine. He was sentenced to 23 years.

He is not an outlier. He is a pattern:

•Manuel Perez Jr., a former CBP officer, was sentenced in March 2026 to 10 years after pleading guilty to conspiracy to distribute five kilograms or more of cocaine, conspiracy to smuggle migrants for financial gain, and bribery of a public official.

•Emanuel Isac Celedon, a former CBP officer in Laredo, was sentenced to 117 months for allowing aliens and cocaine across the border through his inspection lane in exchange for payment.

•A former Border Patrol agent was sentenced to 78 months for taking bribes from drug traffickers, providing real-time information about his checkpoint and whether drug-sniffing dogs were on duty.

•Carlos Victor Passapera Pinott, a former Border Patrol agent, was sentenced to 18 years for drug smuggling and bribery.

A necessary honesty note, the kind the throwaway version of this story never bothers with: not every one of these cases names the Sinaloa Cartel specifically. Several name “a drug trafficking organization,” and Celedon’s case named a different group, the Cartel del Noreste. The point of the cluster is not that Sinaloa bought every one of these officers. The point is structural. The southern port of entry is a known, repeatedly exploited vulnerability, and the organizations that exploit it include the most powerful one.

What the Shape of the Record Tells Us

Lay it out and the asymmetry is impossible to miss. The high-level corruption cases name a governor, a cabinet secretary, police commanders: all Mexican. The American cases name line-level border officers, one badge at a time. And when Treasury moved against the banks that launder the money, the institutions it named were in Mexico City, not New York or Charlotte.

It would be easy to read that last fact as exoneration, to conclude that the American financial system is the clean part of the machine. That reading is the sleight of hand this account is about. Because the same Treasury orders that name the Mexican banks also describe, in their own findings, the American institutions standing at the center of the mechanism. They simply decline to name them.

The system, in other words, climbs all the way to a foreign governor and stops at an American border officer, and it follows the money all the way to the edge of the U.S. banking system and stops there too. The reach is real. So is the place it consistently chooses not to reach. To see why that is not an accident, you have to understand how a dollar actually moves.

Fend Off Fentanyl

On June 25, 2025, the Treasury Department did something it had never done before. Using a new authority Congress granted in the FEND Off Fentanyl Act, the Financial Crimes Enforcement Network named three Mexican financial institutions, CIBanco, Intercam Banco, and the brokerage Vector Casa de Bolsa, as institutions of primary money laundering concern, and cut them off from the U.S. financial system. It was hailed as a landmark, the first strike of a tougher era.

The orders run to seven pages each in the Federal Register. They are precise, detailed, and damning. And buried in their own findings is a fact that nobody covering them stopped on, a fact that quietly rewrites the entire story.

The money these Mexican banks laundered did not stay in Mexico. To become U.S. dollars, it had to pass through American banks. Treasury’s own orders say so. And Treasury’s own orders do not name a single one of them.

That omission is not an oversight. It is the most revealing thing in the documents, and once you see it, you cannot unsee where the gate has been the whole time.

How the Dollar Actually Moves

Start with the mechanism, because the entire revelation lives inside it, and almost nobody outside the compliance world understands how it works.

A Mexican bank cannot simply create U.S. dollars. To move dollars, it needs an account at an American bank, what is called a correspondent account. The American institution is the correspondent; the Mexican bank is the respondent. When cartel proceeds need to move through the dollar system, they flow from the Mexican bank through its correspondent account at a U.S. bank, which is the institution that actually clears the transaction inside the United States. There is no other door. Federal regulators describe the arrangement plainly: a correspondent account is what gives a foreign financial institution a base for moving funds through the U.S. financial system.

And here is the part that matters legally. The American correspondent bank is not a passive pipe. U.S. law requires it to conduct enhanced due diligence on these foreign accounts, to monitor the transactions flowing through them, and it can bear liability for the money laundering of the respondent bank it services. The watching is not optional. It is the correspondent bank’s legal job.

The American bank that clears the dollars is the one institution the law requires to be looking. That is precisely why its absence from the orders is the story.

The Dollars That Buy the Chemicals

Strip the laundering down to its purpose and it stops being abstract. The cartel does not move money for its own sake. It moves money to buy the ingredients for fentanyl, and those ingredients come from China, and Chinese chemical companies do not want pesos. They want dollars. So the entire machine exists to perform one conversion: turn cash skimmed off American streets into U.S. dollars that can be wired to a chemical supplier in China, which then ships the precursors to a Mexican lab, which cooks the fentanyl that comes back north and kills the people whose money started the loop.

That is not a metaphor. It is the literal chain Treasury laid out in its own findings.

In the CIBanco order, FinCEN determined that from 2021 through 2024 the bank processed over $2.1 million in payments on behalf of Mexico-based companies to China-based companies that shipped precursor chemicals to Mexico for illicit purposes. Treasury’s own announcement put the human stakes in the Secretary’s mouth: the banks were enabling the poisoning of countless Americans by moving money on behalf of cartels, making them vital cogs in the fentanyl supply chain.

In the Intercam order, the detail is granular enough to trace. FinCEN found that Intercam had a history of processing USD-denominated funds transfers that finance the importation of precursor chemicals from China, and it documented specific flows. One Mexico-based company tied to a CJNG-affiliated chemical broker sent over 1,000 funds transfers totaling more than $8 million through Intercam to shipping companies in Singapore and Hong Kong from 2021 through 2024. Three separate China-based companies known to have shipped precursor chemicals to Mexico were tied to transfers through Intercam of more than $850,000, more than $925,000, and more than $4 million. And a China-based company connected to a man arrested in 2019 for trafficking fentanyl out of China and India received over forty transfers totaling more than $1.5 million through Intercam from Mexican chemical-trading firms.

Every figure in those findings is denominated in U.S. dollars. And here is the point the orders make unavoidable: a Mexican bank cannot originate a dollar wire to a Chinese company out of thin air. The dollars have to come from somewhere inside the U.S. financial system, which means they have to pass through an American correspondent bank. The chain Treasury describes, Mexican chemical broker to Chinese supplier, paid in dollars, has an American link in the middle of it by physical necessity. Treasury described every other link in detail. The American one it left blank.

Except it did not leave it entirely blank. It left it unnamed, which is different. Read the order’s own description of what Intercam is, and the gate appears in plain sight, three times over: Intercam, FinCEN writes, provides U.S. dollar correspondent banking services through at least two U.S. financial institutions. Two American banks. Present tense. Holding the accounts through which a bank Treasury has just declared a primary money laundering concern moves its dollars. The order states their existence as a plain fact of Intercam’s structure, and then never names them.

Stranger still, the order shows that other American banks already saw the danger and left. In its section on Intercam’s compliance history, FinCEN records that Intercam previously maintained accounts at several U.S.-based financial institutions that exited their relationships with Intercam over compliance concerns, concerns that included wire transfers lacking beneficiary information, checks funded by cash deposits, and a trading account used mainly for same-name wire transfers. So some U.S. institutions looked at Intercam, recognized what they were seeing, and walked away. And at least two others stayed, and were still there, holding the correspondent accounts, when Treasury wrote the order. The order names neither group.

And the order shows the other end of the loop too, the American street where the cash begins. FinCEN documented a suspected money mule who opened accounts at multiple banks in Southern California, made 627 ATM deposits totaling about $2.6 million, and sent 125 wires totaling roughly $1.9 million from those U.S. accounts into an Intercam account in Mexico. A second mule made 431 deposits and sent $1.2 million more. American cash, fed into American banks, wired south to become the dollars that buy Chinese chemicals.

The chemicals are bought with American dollars. The dollars move through American banks. The fentanyl comes back to American streets. The only part of that loop the U.S. government has declined to illuminate is the part that runs through its own financial system, the at-least-two American institutions the order names only as a category and never as a name.

What Treasury Said, in Its Own Words

FinCEN acknowledged the American correspondent relationships directly, and then dismissed the cost of acting on them. Weighing whether cutting Intercam off would create problems for the U.S. financial system, the order states that, given Intercam’s size and the array of correspondent relationships between U.S. and Mexican financial institutions, the macroeconomic impact of prohibiting transmittals involving Intercam would be negligible. The agency named the relationships, on the record, in its own findings. It weighed them. It reasoned about them. And it judged that severing this one bank from them would barely register.

Read against the rest of the order, that word does a great deal of work. Negligible is an assessment of scale: this is a small bank, 0.5 percent of Mexican commercial assets, easily replaced. But the same word quietly answers a question the order never asks out loud. If the correspondent relationships between U.S. and Mexican banks are vast enough that pulling one small respondent out of them is negligible, then the network those U.S. correspondents sit at the center of is enormous, and Intercam was only one node in it. The smallness that makes the action painless is the same smallness that should make a reader ask what the large nodes are doing, and which U.S. banks hold them.

And before issuing the order, FinCEN consulted the Department of Justice, the State Department, the Federal Reserve, the FDIC, the SEC, the CFTC, the Office of the Comptroller of the Currency, and the National Credit Union Administration. The order records that none of them objected. The entire federal financial-regulatory apparatus reviewed this document, with its at-least-two unnamed U.S. correspondents, and signed off.

And then it named only the Mexican bank.

This Is Not New. It Is the Gate That Has Always Been There.

If the correspondent gate were a one-time blind spot, it would be a smaller story. It is not. It is the same mechanism, unnamed in the same way, running through every major cartel-laundering case of the last fifteen years. Once you know to look for the gate, you find it standing open in all of them.

Wachovia, now part of Wells Fargo, processed cartel cash from Mexican casas de cambio between 2004 and 2007, admitting to lax controls across roughly $378.4 billion in transfers. The casas de cambio were the respondents. Wachovia was the correspondent, the American gate through which the money entered the dollar system. In 2010 it forfeited $110 million and paid a $50 million fine. No individual went to prison.

HSBC is the case that named the doctrine. In 2012 it admitted that Mexico’s Sinaloa cartel and Colombia’s Norte del Valle cartel laundered at least $881 million through the bank, much of it routed up through its Mexican unit and into the U.S. dollar system, exactly the correspondent flow. HSBC paid $1.9 billion under a deferred prosecution agreement and admitted no guilt. Then the part that proves design over accident: a later congressional report found that senior Justice Department officials overrode their own prosecutors and declined to charge the bank because they feared a conviction could cause a global financial disaster and cost HSBC its U.S. banking charter. The institution was judged too important to the dollar system to face the consequence its conduct earned.

TD Bank carries the pattern into the present and into fentanyl directly. In October 2024 it became the first bank to plead guilty to felony conspiracy to commit money laundering, paying more than $3 billion. A network led by Da Ying Sze moved over $470 million of drug cash through the bank, bribing employees with more than $57,000 in gift cards to keep the transactions flowing and the reports unfiled. Internal auditors flagged the monitoring failures from 2014 to 2022 while the program stayed deliberately underfunded. Tellers and a few branch-level employees were prosecuted. No executive was. Senators Wyden and Warren wrote to demand why, and got no one in handcuffs at the top.

In every case the shape is identical: the foreign respondent or the bottom-rung employee is named and punished. The American institution at the dollar gate pays a fine. The people who ran it walk.

The Connection, Stated Once and Plainly

Here is the line this account exists to draw, the one assembled entirely from public documents and never put together in public before:

The 2025 fentanyl sanctions, praised as the toughest cartel-finance action in U.S. history, reproduce the exact enforcement asymmetry of the cases they were supposed to surpass. They name the foreign bank and leave the domestic gate unnamed.

The mechanism never changed. Cartel money becomes dollars by passing through an American correspondent bank that the law requires to be watching. For fifteen years the consequence has landed everywhere except on that gate: on the Mexican casa de cambio, on the foreign respondent bank, on the bribed teller, on the corporate balance sheet that absorbs a fine as a cost of business. The 2025 orders had the chance to break that pattern with a brand-new authority and a mandate to be ruthless. Instead they pointed the new weapon outward, at the Mexican institutions, and downward, at border money-services businesses, and left the structural center of the mechanism exactly where it has always been: acknowledged, weighed, and unnamed.

The Question the Documents Force

This account will not name an American bank it cannot prove, and the orders do not name one. But the orders force a question that the agencies who wrote them have not answered, and that the public is entitled to ask:

Treasury determined that Intercam moved fentanyl-precursor dollars through the U.S. financial system, and stated, three times in its own order, that Intercam does so through at least two U.S. financial institutions. Which two? And what did they know that the U.S. banks who exited Intercam already knew?

Either those correspondent banks conducted the enhanced due diligence the law requires and failed to stop transactions Treasury later found to be financing fentanyl production, or they did not conduct it. There is no third option. Both possibilities point at an American institution standing at the gate. And in the public record assembled here, neither the orders, nor the press releases, nor any enforcement action to date has named which institutions those were, or said what consequence, if any, they faced.

That silence is the finding. Not a hidden roster of corrupt bankers, but a structural decision, made and remade for fifteen years and again in the supposedly unprecedented action of 2025: to follow cartel money right up to the American gate and then stop, to name the foreign bank and the foreign respondent and the low-level teller, and to leave unspoken the name of the U.S. institution that the law itself says was supposed to be watching when the dollars went through.

But gates do not stay still.

The assumption underneath much of the public conversation is that cartel finance still looks the way it did a decade ago: bulk cash, shell companies, correspondent accounts, and money moving through the traditional banking system. That is still part of the picture. It is no longer the whole picture.

Because while regulators were learning how to map one network, the network was already evolving into another.

Cryptocurrency and Cartels

Over the last several years, federal investigators have been documenting the emergence of a financial architecture that is more global, more technologically sophisticated, and in some ways more difficult to disrupt than the system that came before it. The same cartel organizations moving fentanyl into American communities are increasingly relying on Chinese underground banking networks, cryptocurrency transactions, trade-based laundering schemes, and international broker networks to move proceeds across borders and back into the supply chain.

The names change. The technology changes. The gate changes.

The question does not.

In 2024, federal prosecutors in Los Angeles charged a laundering network tied to the Sinaloa Cartel with moving more than $50 million through Chinese brokers using a mixture of trade-based schemes and cryptocurrency transactions designed to conceal the origin of drug proceeds. Around the same time, a Las Vegas man was convicted for taking cartel cash, converting it into Bitcoin, and moving it through layers of digital wallets to obscure its source.

These cases are important for what they reveal. Cryptocurrency is not replacing the cartel's business model. It is being woven into it. The drugs are still sold on American streets. The cash is still collected in the United States. The money still has to cross borders and eventually purchase the precursor chemicals that keep the fentanyl pipeline alive. The difference is that some of those movements now happen through wallets and blockchain transactions instead of correspondent accounts and wire transfers.

The underlying system remains remarkably familiar. U.S.-based couriers collect bulk cash. Chinese brokers seeking U.S. dollars for clients trying to move wealth out of China absorb that cash through their own business networks. Cryptocurrency often serves as the bridge, allowing value to move internationally without relying entirely on traditional banking channels. Those same networks then facilitate payments to Chinese chemical suppliers whose products ultimately arrive in Mexican laboratories.

The result is a transnational partnership spanning three continents. Chinese suppliers provide the precursor chemicals. Mexican cartels manufacture and distribute the drugs. Chinese money-laundering organizations help recycle the proceeds. And increasingly, cryptocurrency helps connect each stage of the process.

Regulators have begun responding. Treasury has sanctioned members of Los Chapitos who used cryptocurrency and wire transfers to move fentanyl proceeds. It has identified specific blockchain addresses tied to cartel operations. The Department of Justice has pursued Chinese chemical manufacturers and financial facilitators. Blockchain analysts have traced wallets connected to sanctioned entities and documented the impact those actions have had on cartel-linked financial flows.

But the broader lesson is not technological. It is still structural.

For years, the question was who stood at the correspondent banking gate. Now investigators are confronting a system with new gates: crypto exchanges, stablecoin issuers, underground banking networks, and international brokers operating across multiple jurisdictions at once.

The technology has changed. The money still moves. And the same question remains hanging over every new system that emerges:

When fentanyl money passes through a gate, who gets named, who gets prosecuted, and who disappears from the story?

A note on sourcing and method

This account is built on the FinCEN order for Intercam Banco (90 FR 27777, published in the Federal Register on June 30, 2025) read in full, together with the parallel CIBanco and Vector orders and the U.S. Treasury announcement of June 25, 2025; on federal banking regulators’ own published descriptions of correspondent-account due-diligence obligations; on State Department and OFAC designation records; on the unsealed federal indictments and convictions of the Mexican officials and U.S. border officers named above; and on the corporate guilty pleas, deferred prosecution agreements, and settlement records of Wachovia (2010), HSBC (2012), and TD Bank (2024), together with the related congressional report on the HSBC non-prosecution decision and on-the-record letters from sitting U.S. senators. The Intercam order states three times that the bank maintains correspondent banking relationships with at least two U.S. financial institutions, and separately records that other U.S. institutions previously exited their relationships with Intercam over compliance concerns; it names none of these U.S. institutions. The order’s assessment that the macroeconomic impact of the action would be “negligible,” given “the array of correspondent relationships between U.S. and Mexican financial institutions,” appears verbatim in section IV.B (page 27782). The claim that dollar-denominated transfers must clear through a U.S. correspondent institution is a description of how the correspondent banking system functions, not an allegation against any specific named American bank. No U.S. correspondent bank is identified or accused here, because the public record does not identify one; the question of which institutions cleared the transactions, and what they knew, is posed as the unanswered question the order creates.
