Why Banks Are Worried About Stablecoins

How It Works

The bank business model has three pillars: deposits, lending, and payments. Stablecoins threaten all three. On deposits, a consumer holding $10,000 in USDC is not holding it in a bank account — the bank loses that funding. On payments, every business transaction conducted in stablecoins bypasses the card network and the bank that processes transactions. On the gatekeeper role, stablecoins give consumers and businesses access to global financial infrastructure without needing a bank account.

The deposit threat is most immediate. Banks fund their lending operations with cheap customer deposits. If stablecoins offer holders a dollar-equivalent asset that also pays 4% yield, the rational consumer choice is obvious. Banks cannot match 4% yield on checking accounts without dramatically compressing their profit margins — which is built into the current model by extracting the gap between deposit costs and lending income.

The payments threat is longer-term but potentially larger. Card network fees (2 to 3% of every transaction) are one of banking's most lucrative income streams. Stablecoin payments bypass this entirely, potentially saving merchants and consumers hundreds of billions annually. As merchant acceptance of stablecoin payments grows, card fee revenue at banks and card networks faces structural pressure.

Banks' response has been defensive lobbying (restrict stablecoin issuance, ban yield) and offensive investment (build their own blockchain products, acquire fintech companies). Both strategies reflect the recognition that the status quo is not sustainable.

Why It Matters

Banks' concerns about stablecoins are not irrational — stablecoins do threaten the existing business model. But the public policy question is different: should governments protect banks' current business model from competition, or should they allow consumers to benefit from more efficient financial technology? The banking industry's lobbying power means this question gets answered partly in their favor, regardless of what would most benefit ordinary Americans.

Real-World Example

Bank of America earned approximately $13 billion in net interest income in a single quarter of 2023, partly by paying 0.02% on hundreds of billions in checking deposits while earning 6 to 7% on loans. If just 10% of those deposits migrated to yield-bearing digital wallets, the bank would lose roughly $1.3 billion in quarterly earnings. This math explains exactly why the bank's lobbyists are spending eight figures annually in Washington to prevent yield-bearing stablecoins from becoming legal and accessible.
