US Designation of Brazil Groups Sparks Compliance Talks in Banks

After the United States designated Brazil’s largest criminal organizations as terrorist groups, Brazilian banks have turned to Mexican financial peers for guidance on upgrading compliance and risk-management systems. The move aims to prevent exposure to clearing-system restrictions and asset freezes previously seen in Mexico, while accelerating adoption of advanced, non-list-based due diligence practices. The shift underscores rising pressure on regional banks and fintechs as US anti-money laundering enforcement intensifies through the Financial Crimes Enforcement Network.

The decision by the United States to designate Brazil’s two largest criminal groups as terrorist organizations has prompted Brazilian banks to engage with financial institutions in Mexico to mitigate potential regulatory repercussions. Representatives from the Brazilian financial sector have initiated discussions with consultants and Mexican bank executives to examine risk management strategies. These institutions aim to adopt compliance best practices, particularly in identifying clients with indirect ties to illicit networks.

Bankers in Brazil have expressed concern that US regulatory bodies could deploy enforcement mechanisms similar to those used against Mexican financial entities last year. In that case, three Mexican institutions were effectively excluded from the US financial system following money laundering allegations linked to drug trafficking, forcing the gradual sale of their operations. The action triggered an industry-wide push across the regional banking sector to strengthen internal monitoring systems for potentially illicit funds.

According to Jeremy Paner, a Washington-based partner, Hughes Hubbard & Reed, the terrorist designations require Brazilian banks to significantly restructure their compliance frameworks. “A simple cross-check against US sanctions lists is no longer sufficient,” Paner said. “Banks must carry out more rigorous due diligence, as these new sanctions are not strictly list-based.”

The US administration designated Primeiro Comando da Capital (PCC) and Comando Vermelho (CV) as terrorist organizations. The PCC operates a sophisticated money laundering network embedded in fintech firms and fuel distribution infrastructure. The CV, based in Rio de Janeiro, was recently the target of the deadliest police operation in Brazil’s history in October.

The current situation mirrors the US approach in Mexico, where major drug cartels were similarly designated. Subsequently, the US Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) implemented strict measures that restricted selected Mexican entities’ access to US clearing systems.

A key operational challenge for Brazilian compliance officers is managing account holders suspected of criminal ties who do not appear on standard international watchlists. Financial institutions are evaluating how to comply with US requirements without violating Brazil’s domestic banking secrecy and privacy laws. In addition, executives are analyzing how prior regulatory responses in Mexico have influenced bank decisions in both the short and medium term.

Regulatory Penalties and Asset Reconfiguration in Mexico

Brazilian banks’ interest in Mexican financial institutions comes amid a structural reorganization of Mexico’s banking sector. An estimated MX$3.2 trillion (US$183 billion) in fiduciary portfolios shifted across the Mexican banking system within 12 months of FinCEN imposing sanctions on CIBanco and Intercam Banco, according to a report by consultancy firm TMSourcing. The report, titled Mercado Fiduciario en México 2025–2026, states that the forced exit of these entities triggered a significant reallocation of trust assets to alternative administrators.

Banco Multiva emerged as the primary beneficiary of these capital flows, absorbing more than MX$1.66 trillion (US$94.71 billion) in less than six months to become the country’s largest fiduciary administrator. Additional inflows were captured by Actinver, Invex, and Grupo Financiero Inbursa, which received between MX$50 billion (US$2.85 billion) and MX$300 billion (US$17.11 billion).

This migration of assets occurred as the broader banking trust market grew 25% cumulatively between 2022 and 2026. However, TMSourcing noted that high asset concentration limits competition, stating that “the current structure limits effective competition, reduces client choice, and weakens incentives for innovation and efficiency.”

The disruption began in June 2025, when FinCEN issued its first enforcement action under the Fentanyl Sanctions Act against CIBanco, alleging the institution facilitated precursor chemical transactions linked to drug cartels. The designation cut CIBanco off from the US financial system. While President Claudia Sheinbaum and the Ministry of Finance initially questioned the lack of formal evidence, the National Banking and Securities Commission (CNBV) invoked Article 129 of the Credit Institutions Law and appointed provisional administrators from Alvarez & Marsal México to safeguard creditors.

The operational fallout was immediate. Visa terminated its agreement with CIBanco on June 30, 2025, disabling approximately 220,000 cards, while more than US$38 million in fiduciary assets held in U.S. institutions became inaccessible. CIBanco filed a civil lawsuit in a US federal court against the US Department of the Treasury in August 2025, though the case was later withdrawn after FinCEN extended the effective date of its prohibition order.

The CNBV officially revoked CIBanco’s operating license in October 2025 due to severe liquidity constraints. The Institute for the Protection of Bank Savings (IPAB) subsequently initiated a liquidation process on Oct. 13, covering insured deposits up to 400,000 UDIs, equivalent to approximately MX$3.4 million (US$193,912) per depositor.

FinCEN recently amended its prohibition order to allow Mexican authorities to complete the liquidation of the bank’s remaining assets. According to the US Treasury, the decision reflects “the shared commitment of the United States and Mexico to protect the financial systems of both countries from cartels and drug traffickers.”
