Day 666: US Treasury OFAC Sanctions 11 Sinaloa Cartel Money Launderers and 6 Ethereum Wallets — Los Chapitos Cash-to-Crypto Pipeline Targeted

On Day 666 of the Sinaloa cartel civil war — May 20, 2026 — the US Treasury Department's Office of Foreign Assets Control (OFAC) designated 11 individuals and 2 entities connected to the Sinaloa Cartel's Los Chapitos faction for laundering drug proceeds through cryptocurrency, in the most significant cryptocurrency-focused financial enforcement action targeting the Sinaloa Cartel during the conflict era. Six Ethereum wallet addresses were simultaneously added to the Specially Designated Nationals (SDN) list. The action was coordinated with the DEA and Homeland Security Investigations (HSI). The State Department issued a companion statement designating two Sinaloa Cartel networks under the Foreign Narcotics Kingpin Designation Act for trafficking illicit fentanyl. At the center of the network is Armando de Jesus Ojeda Aviles, described by OFAC as Los Chapitos' primary money laundering architect for their US-based drug cash. Ojeda Aviles ran a cash-to-crypto pipeline: US drug sales cash was collected by couriers, routed through middlemen to unlicensed over-the-counter (OTC) cryptocurrency brokers, converted into USDT stablecoins, and transmitted across the border to Mexico — evading traditional financial surveillance. Five of the six designated Ethereum addresses are attributed to a single individual, consistent with multi-wallet asset fragmentation to impede blockchain tracing; one ETH address sent $894 USDT on April 27, 2026 after more than a year of dormancy, suggesting the network remained active immediately before designation. Also designated: Jesus Alonso Aispuro Felix (blockchain drug proceeds mover) and Jesus Gonzalez Penuelas (fugitive Chapitos distributor, already subject to a $5M US State Department reward). The two sanctioned entities are Gorditas Chiwas — a Chihuahua restaurant used as a financial front — and Grupo Especial Mamba Negra — a security firm used as cover for laundering operations. The May 20 action is the fourth major US financial enforcement strike against the Sinaloa Cartel since April 20, 2026 (April 20: visa restrictions on 75 associates; April 24: OFAC sanctions on a 23-person fentanyl precursor network; April 29: DOJ SDNY criminal indictment of Governor Rocha Moya and nine officials). Taken together, these actions represent a comprehensive campaign targeting Los Chapitos from financial infrastructure through state political corruption. The extradition standoff enters Day 21 with three of ten SDNY-indicted officials (Mérida Sánchez, Díaz Vega, Inzunza Cazárez) in US federal custody at Brooklyn MDC and seven — including Rocha Moya and Mayor Gámez Mendívil — remaining in Mexico. El Mayo Zambada's EDNY sentencing before Judge Brian Cogan remains set for July 20, 2026. Running conflict toll: ~2,425+ (Noroeste) / 3,000+ (WSJ) homicides since September 9, 2024.
