The Chilean financial landscape has seen significant regulatory and judicial actions regarding institutional conduct and market integrity. Historically, the 1983 collapse of Banco de Santiago highlighted the risks of connected lending and speculative operations, influencing a global regulatory shift toward evaluating banking operations based on their ‘substance is more important than form.’

More recently, enforcement actions have targeted market manipulation and consumer rights violations. The Commission for the Financial Market (CMF) upheld a fine against Asesorías e Inversiones A&C SpA for allegedly placing over 34,000 fictitious orders to manipulate stock prices on the Santiago Stock Exchange. Additionally, the Supreme Court upheld a fine against Banco BICE for unilaterally modifying mortgage interest rates and failing to provide necessary pre-contractual information to clients.
