BofA argues that AI agents could gradually make excess cash more mobile and raise banks' funding costs. Early Muse adoption demonstrates consumer interest, but the report says bank disruption is unproven until deposit costs and deposit betas accelerate.
- Muse had about 2.5 million cumulative US downloads and about 557,000 daily active users as of September 19.
- The report considers AI-driven deposit disruption evolutionary rather than imminent because trust, privacy and account-access concerns slow adoption.
- The key evidence would be higher deposit costs, lower non-interest-bearing balances and deposit betas above normal rate-cycle or competitive effects.
- Banks with integrated banking, brokerage and wealth ecosystems may be better able to retain customer assets through internal balance optimization.
