Moody's warns of growing bank dependence on AI companies

Credit rating agency Moody's has warned of escalating risks as financial institutions accelerate artificial intelligence adoption. Banks leverage AI-driven automation and efficiency gains, yet face mounting security and privacy challenges. According to a UK Treasury report, 75% of British financial firms already use AI for critical operations, from insurance claims processing to credit analysis. Concentration in just a few AI models creates dangerous systemic dependence—a service outage at companies like OpenAI or Anthropic would rapidly impact the banking sector. Regulators increasingly focus on AI supply-chain risks and operational reliability. Adding to concerns: these companies still operate at a loss and face investor pressure for profitability, raising the risk of future price increases.
