Financial institutions have undergone various operational and technical shifts. In Argentina, Banco Nación implemented updates to its home banking platform, which led to user confusion regarding interface changes and access channels. Experts noted that these transitions could potentially increase vulnerability to phishing scams. During the same period, Mercado Pago has been consolidating its role in the banking ecosystem, offering more accessible personal loan and financing options than some traditional banks.

Technical disruptions affecting cryptocurrency operations intensified for Nubank and Mercado Pago. On November 6, both companies temporarily suspended cryptocurrency deposits, withdrawals, and transfers due to instabilities caused by external third-party providers. Nubank attributed its issues to an external data provider for transaction verification, emphasizing that internal buying and selling of assets continued to function normally and that customer assets remained secure. Mercado Pago attributed its disruption to an incident involving a provider of risk monitoring and anti-money laundering services, which led to the blocking of certain transfers to external wallets in Brazil, Chile, and Mexico.

By the evening of November 6, both Nubank and Mercado Pago had normalized their cryptocurrency deposit and withdrawal services. Mercado Pago stated that pending amounts would be credited automatically following the restoration of services. These disruptions occurred alongside reports of partial instability in the Pix instant payment system in Brazil, which affected multiple financial institutions including Itaú, Bradesco, and Santander. The Brazilian Central Bank noted that the Pix issue was quickly resolved.
