# Bank Of America Moat

Status: published. Policy: company-analysis-1.

Bank of America has a narrow moat supported by inexpensive deposit funding and established banking, payments and wealth relationships. Large noninterest-bearing balances, continued engagement and client inflows demonstrate advantages beyond margins alone. Switching costs are inferred from relationship depth rather than contractual lock-in. Pricing power is mixed: deposit economics improved, while card yields, card fees and AUM pricing weakened. Competition and demonstrated deposit migration limit confidence in wider protection.

## cost_advantage

The established deposit franchise provides a current funding-cost advantage relative to the Corporation's wholesale funding alternatives. Second-quarter 2026 average noninterest-bearing deposits were $533.3 billion, while interest-bearing deposits cost 1.98%, versus 4.70% for repo-related funding and 4.85% for long-term debt. Deposit balances and engagement support the franchise; these figures do not establish a cost lead over named banks.

Durability: The large transaction deposit base and continuing customer activity support persistence, but the supplied evidence does not demonstrate an exceptional advantage through multiple rate cycles.

Risks: Customers can move balances to higher-yielding alternatives, as wealth clients demonstrably did in 2025. Competition can require higher deposit rates, and technology lowers distribution barriers.

Invalidation: Sustained loss of noninterest-bearing balances, accompanied by replacement with materially more expensive funding and persistently weaker deposit spreads despite stable market rates, would invalidate the funding advantage.

## switching_costs

Banking, payments and wealth relationships create modest relationship-based switching friction. The disclosed banking relationship among 64% of GWIM clients, active digital usage, positive wealth flows and growth in deposits from existing commercial clients support ongoing reliance. Actual switching costs and customer-level retention rates are not quantified.

Durability: Repeated transactions and multiple relationships can sustain engagement. The evidence supports a current relationship advantage, with less certainty about its long-term strength or exclusivity.

Risks: Clients can maintain multiple providers and move cash without leaving the broader relationship. Short or cancellable customer contracts and lower technology barriers limit lock-in.

Invalidation: Persistent net relationship losses, negative client flows excluding market movements, declining active usage and continuing withdrawal of existing-client operating deposits would undermine the inferred switching friction.

Competitors: Citigroup, Morgan Stanley, Goldman Sachs, Wells Fargo, JPMorgan Chase
