The U.S. Treasury's Office of Foreign Assets Control this week sanctioned a crypto laundering network tied to the Sinaloa Cartel, hitting infrastructure used to move drug trafficking proceeds through digital assets. In a separate enforcement action, Venezuelan authorities shut down a 4,000-unit ASIC mining farm — the largest such raid in the country this year. Meanwhile, Brazilian banking giant Bradesco announced it is entering cryptocurrency custody services, a move that signals growing institutional adoption in Latin America.
The OFAC action
OFAC's sanctions target specific entities and wallets that prosecutors say form part of the Sinaloa Cartel's crypto money-laundering pipeline. The designation freezes any U.S.-connected assets and bars Americans from dealing with the listed parties. It's the latest in a string of Treasury actions aimed at disrupting how transnational criminal organizations use crypto to launder illicit proceeds. The cartel has long used digital currencies to layer profits from fentanyl and other drug sales, and regulators have zeroed in on the exchange and wallet infrastructure enabling those flows. The sanctions also serve as a warning to other crypto service providers: if you're facilitating cartel money, you're in the crosshairs.
The Venezuela raid
Venezuelan authorities this month shut down a mining farm packing 4,000 ASIC miners, according to local reports. The operation, one of the largest ever discovered in the country, was running without proper authorization. The government has been cracking down on unlicensed mining as it wrestles with chronic electricity shortages and a collapsing economy. The raid signals that even as crypto adoption grows among Venezuelans seeking a hedge against hyperinflation, the state is tightening control over the mining sector — especially operations that draw on heavily subsidized power. It's a reminder that the regulatory environment for crypto in Venezuela remains unpredictable.
Bradesco's move
Bradesco, one of Brazil's largest financial institutions, is entering the crypto custody business. The bank will offer institutional clients a regulated vault for storing digital assets. Brazil has become a hotbed for crypto activity — several major banks and exchanges already provide trading and custody services. Bradesco's entry adds a heavyweight to that mix, potentially drawing more institutional capital into the space. The timing makes sense: as Brazil's securities regulator tightens rules around digital assets, traditional finance is stepping in to offer compliant solutions. It's a sign that custody is becoming a standard banking offering, not just a specialist niche.
