Meta's Muse AI agent starts eating into banks' cheapest funding source
Meta's new Muse personal AI agent is helping users audit spending, cancel subscriptions, and could soon shift idle cash into higher-yield accounts — a pattern economists say threatens a core piece of how banks fund themselves.
For years, subscription businesses have benefited from a simple fact of consumer behavior: people are much better at signing up than canceling. They forget what they joined. They stop using services but keep paying. Muse is designed to break that inertia at scale: consumers who gave the AI access to banking and credit card statements found it to be a great budgeting coach, leading them to cancel unnecessary subscriptions. The stakes go well beyond streaming apps — Apollo chief economist Torsten Slok warned that "Muse and similar agentic AI assistants could soon sweep household cash automatically into accounts paying 3.3% to 5.0%, instead of the 0.1% national average on checking accounts," which could cause banks to "lose a large share of the cheap deposits they rely on to make loans."
If an AI agent can watch your accounts and act on inertia, "set and forget" pricing — subscriptions, insurance premiums, low-yield savings — gets much harder for companies to rely on. Expect more scrutiny of your own recurring charges now that a tool exists to do it automatically.
Finance: Watch bank deposit costs and net interest margins. Investors are already pricing this in — bank, insurer, and travel stocks sold off on fears that agentic AI erodes the "inertia premium" these sectors have quietly collected for years.
Managers: If your company sells anything that depends on customers not paying close attention — recurring billing, auto-renewals, opaque pricing — this is worth a line in your next planning review.
Do this: If you're curious, try connecting a budgeting or AI agent to one account first and see what it surfaces before granting broader banking access.
