McKinsey: banks cut manual work by up to 50% with AI agents
A McKinsey report describes how banks are moving toward AI-based "coworkers" able to plan tasks, use tools and coordinate actions across systems. A US bank applied the model to fund accounting, reconciliations, middle-office operations and architecture reviews, and in one of those evaluations cut manual work by 40% to 50%. The consultancy warns that an error can affect production systems, expose customer data or breach rules, and recommends limited permissions, dedicated identities and final human authorization.
