US Sanctions Sinaloa Cartel Crypto Laundering Network Tied to Fentanyl
The U.S. Treasury Department sanctioned more than a dozen individuals and entities linked to the Sinaloa Cartel on May 20, 2026, targeting two distinct cash-to-crypto laundering networks that allegedly funneled fentanyl trafficking proceeds through digital currency channels.
The Office of Foreign Assets Control (OFAC) said the action covered networks that collected bulk cash from drug sales inside the United States and converted it into cryptocurrency for transfer to cartel operatives in Mexico, according to a Treasury press release.
What to Know
- OFAC sanctioned two networks tied to the Sinaloa Cartel’s fentanyl revenue, naming key cash-to-crypto brokers and listing six Ethereum addresses.
- The designations were made under executive orders targeting illicit drugs and terrorism, reflecting the cartel’s dual classification as a narcotics trafficker and a Foreign Terrorist Organization.
What the sanctions allege about the laundering network
Treasury identified Armando de Jesus Ojeda Aviles as the coordinator of bulk cash collection operations inside the United States. Ojeda Aviles allegedly facilitated the conversion of that cash into cryptocurrency for ultimate transfer to the Sinaloa Cartel in Mexico.
Jesus Alonso Aispuro Felix served as the chief money broker for the network, according to Treasury. He allegedly brokered bulk transfers of drug proceeds through digital currency addresses.
The sanctions action also reached businesses linked to cartel-affiliated individuals. AP News reported that the designations covered Gorditas Chiwas, a Chihuahua restaurant, and Grupo Especial Mamba Negra, a security firm linked to Alfredo Orozco Romero, as part of the broader enforcement sweep.
Treasury noted that the Sinaloa Cartel was first identified under the Kingpin Act on April 15, 2009, designated under Executive Order 14059 on December 15, 2021, and classified by the State Department as both a Foreign Terrorist Organization and a Specially Designated Global Terrorist on February 20, 2025. The May 20 action invoked EO 14059, which targets illicit drugs, and EO 13224, which targets terrorists and their supporters.
Treasury said that turf wars within the cartel’s factions have killed over 600 people in Sinaloa since September 2024.
How the cash-to-crypto pipeline allegedly worked
The laundering cycle began with U.S.-based couriers collecting physical cash from drug sales. That cash was then converted into stablecoins, swapped on decentralized exchanges, and routed onward to centralized exchanges, according to a Chainalysis analysis of the laundering path.
The multi-hop approach, moving from cash to stablecoins to DEX swaps to CEX deposits, mirrors techniques that have drawn increasing scrutiny from regulators. Recent enforcement actions such as Missouri’s lawsuit against CoinFlip over crypto ATM fraud highlight how fiat-to-crypto conversion points remain a persistent compliance gap.
OFAC’s sanctions action page listed six Ethereum addresses connected to the laundering network: five tied to Ojeda Aviles and one to Rodrigo Alarcon Palomares, according to the OFAC filing.
The explicit listing of blockchain addresses in a sanctions filing means that any U.S. person or entity transacting with those wallets faces potential penalties. Exchanges and wallet providers are required to screen transactions against the OFAC Specially Designated Nationals list, which now includes these addresses.
Why the case matters for crypto compliance
The designations signal that U.S. authorities increasingly view cryptocurrency rails as integral to cartel finance, not peripheral to it. By naming specific Ethereum addresses alongside traditional targets like shell companies and real estate, OFAC is treating on-chain infrastructure the same way it treats bank accounts and corporate vehicles.
For centralized exchanges and OTC desks, the action raises the compliance bar. Any platform that processed transactions from the six listed addresses, or from wallets that interacted with them, now faces potential sanctions exposure. The Chainalysis analysis of the DEX-to-CEX routing pattern suggests that transaction monitoring must extend beyond direct counterparty screening.
The case also connects to broader concerns about stablecoin oversight. The laundering path described, converting cash into stablecoins before swapping on DEXs, underscores why stablecoin issuers like Tether face ongoing questions about their role in illicit finance prevention.
Cross-chain exploits and bridge vulnerabilities add another layer of complexity to sanctions enforcement. As seen in the recent MAPO token incident involving a cross-chain bridge exploit, decentralized infrastructure can create gaps that complicate compliance screening and asset tracing.
All property and interests in property of the designated individuals and entities that are within U.S. jurisdiction are now blocked. U.S. persons are broadly prohibited from dealing with them absent specific OFAC authorization.
