BCG·medium signal

BCG's 2026 report 'How Retail Banks Can Put Agentic AI to Work' projects AI agents can increase bank profitability by 30% and reduce costs 30-40% by 2030, unlocking $370B in annual profit. Agents currently represent 17% of AI-derived value across industries, expected to reach 29% by 2028. BCG identifies three maturity stages (deploy, reshape, invent) and warns banks that delay risk becoming 'structurally irrelevant.' For fintech SaaS builders, the opportunity is building the agent infrastructure banks need.
