Mexico's National Banking and Securities Commission (CNBV) announced that CIBanco, S.A., Institución de Banca Múltiple will proceed with voluntary liquidation after its shareholders requested revocation of its authorisation to operate as a multiple banking institution, which the CNBV’s Governing Board approved and published in the Official Gazette of the Federation. From 10 October 2025, the Institute for the Protection of Bank Savings (IPAB) assumed the role of liquidator and began paying savers for deposits and other operations treated as guaranteed obligations under bank deposit insurance. Payouts are being made up to a coverage limit of 400,000 Investment Units (UDIS) and are funded through the Bank Savings Protection Fund, which is financed by mandatory contributions from multiple banking institutions and does not rely on public resources. IPAB has provided an IT platform for claim registration and tracking, requiring savers to submit their details as shown on their last CIBanco account statement and provide a CLABE account at a multiple banking institution to receive electronic transfers; the deposit insurance coverage is automatic and free. The communication also stated that the event does not represent a risk to banking system stability, noting the system remains above regulatory minimum levels.
