Summary
- The Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned more than a dozen individuals and entities linked to the Sinaloa Cartel, focusing on networks laundering fentanyl proceeds through crypto.
- The action’s target – the Los Chapitos faction’s chief money launderer and his associates – converted cash from U.S. drug sales into crypto for transfer to Mexico.
- These sanctions represent a targeted effort by U.S. authorities to dismantle the cash-to-crypto pipelines utilized by transnational narco-terrorist organizations.
On May 20, 2026, U.S. authorities sanctioned a Sinaloa Cartel-run money laundering network that moved the cash proceeds of fentanyl sales across the U.S.-Mexico border using cryptocurrency. This enforcement action dismantles a specialized financial cell responsible for converting street-level fiat drug proceeds into cryptocurrency, allowing the cartel to bypass the traditional banking sector.
Los Chapitos’ fentanyl cash-to-crypto pipeline
This sanctions designation’s crypto nexus centers on a Sinaloa-based laundering network operated by Armando de Jesus Ojeda Aviles. Ojeda Aviles became the primary money launderer for the Sinaloa Cartel’s Los Chapitos faction, following the murder of his predecessor, Mario Alberto Jimenez Castro, whom OFAC sanctioned in September 2023 for laundering fentanyl proceeds with crypto.
Ojeda Aviles oversees a complex logistics web involving U.S.-based couriers who collect bulk quantities of physical cash derived from illicit narcotics sales. Once aggregated, his network facilitates the conversion of this fiat currency into cryptocurrency.
Key figures within this crypto-laundering cell include:
- Jesus Alonso Aispuro Felix: The network’s chief money broker. Aispuro Felix manages the digital side of the operation. He is responsible for brokering high-volume transfers of drug proceeds through designated crypto addresses.
- Rodrigo Alarcon Palomares: An associate tasked with facilitating physical money pickups in the United States. In April 2024, a federal grand jury in Colorado indicted him on three counts of laundering drug proceeds through cryptocurrency.
On-chain mechanics and the drug proceeds laundering cycle
The illicit funds started at the street level. Couriers of the Los Chapitos network like Alarcon Palomares collected the cash proceeds from fentanyl sales in the U.S. Then, cartel brokers converted the cash funds into stablecoins via bulk transactions.
Chainalysis Reactor highlights the onchain flow of funds. It followed a pattern: First, Ojeda Aviles-linked wallets swapped between stablecoins using decentralized exchanges, then forwarded the funds onto centralized exchanges – likely to cash out. The network’s aim was to simplify moving drug proceeds cross-border.
Implications for sanctions compliance and monitoring
Disrupting the cartel’s money laundering pipeline is central to the U.S. government’s counter-narcotics strategy. Cartels are now frequently using courier networks and tokens — especially stablecoins — to move illicit funds globally. By designating specific crypto-laundering cells, the Treasury is degrading the cartel’s ability to finance its operations.
With Chainalysis’s solutions, organizations can monitor and detect exposure to high-risk activity associated with these designated operatives. We have labeled the relevant cryptocurrency addresses associated with this cartel laundering network in our product suite and will continue to monitor the on-chain fallout from today’s designations.
