TLDR
The Bank for International Settlements (BIS) is warning that dollar stablecoins are beginning to compete directly with bank deposits, which could erode traditional banks core funding base over time.
- BIS argues that stablecoins and bank deposits both offer stable-value payments, so shifting cash balances into USDT or USDC instead of deposits can weaken banks cheap, insured funding.
- Global watchdogs warn that a large stablecoin run could force issuers to sell reserve assets and pull deposits from banks, transmitting stress from crypto markets into traditional finance.
- Regulators are now debating whether to regulate stablecoins more like deposit products, while banks experiment with tokenized deposits and central banks explore CBDCs.
Deep Dive
1. How Stablecoins Compete With Deposits
A BIS commentary finds that stablecoins compete directly with traditional bank deposits because both let users hold a stable dollar value and make payments without price volatility, especially via USDT and USDC on major chains.
Unlike deposits, which usually benefit from deposit insurance and prudential bank regulation, stablecoins rely on private issuers reserves and contractual redemption terms, with no guaranteed backstop.
BIS notes that if transaction balances migrate from deposits into stablecoins, banks lose part of their low-cost retail funding and may be pushed toward more expensive wholesale markets to finance lending.
Growth in digital dollars can slowly shift the economics of banking, even if users think of it as just moving cash between apps.
2. Why This Can Threaten Bank Funding And Stability
The Financial Stability Board (FSB) estimates the stablecoin market around 300 billion dollars, with roughly 99 percent pegged to the US dollar, and warns that a severe redemption wave could resemble a bank run.
If many users redeem at once, issuers may need to sell reserve assets such as Treasury bills or withdraw large deposits from commercial banks, draining bank liquidity and tightening funding conditions.
Because many stablecoin structures and reserves span multiple jurisdictions, the FSB highlights that redemptions could concentrate on one entity while reserves sit elsewhere, delaying payouts and amplifying stress for both issuers and banks.
A big shock to a major stablecoin could quickly feed back into banks that hold its reserves, so regulators are treating stablecoins as a potential new channel for runs.
3. How Banks And Regulators May Respond
Another BIS paper finds that higher bank deposit rates slow stablecoin growth, suggesting that competitive deposit returns can keep some balances inside banks rather than on-chain.
Regulators are weighing whether to impose deposit-like requirements on stablecoins, including strict reserve rules, stress testing of redemption capacity, and closer supervision, especially for large issuers.
Banks, meanwhile, are exploring tokenized deposits and central banks are piloting CBDCs, offering on-chain money that keeps funding within the banking system while still modernizing payments.
For crypto users, the stablecoin landscape could become more regulated and bank-like over time, affecting which tokens survive, how they are backed, and how easy they are to use anonymously.
Conclusion
BISs warning is less about an immediate crisis and more about a structural shift: if stablecoins keep absorbing everyday dollar balances, banks could lose a key source of cheap funding and become more fragile in stress.
For crypto, this means stablecoins are now firmly on the regulatory radar as systemically relevant payment tools, not just trading chips, and the next phase of regulation and bank innovation will shape how resilient this digital cash layer really is.
