The Bank for International Settlements warned that the rapid growth of stablecoins could begin pulling deposits away from commercial banks in its 2026 Annual Economic Report. The institution, often described as the central bank for the world's central banks, stated this deposit migration could make bank funding more expensive and reduce lending capacity. The warning arrives as the global stablecoin market has grown to well over $250 billion in circulation, with regulators across the United States, Europe and Asia developing legal frameworks aimed at integrating stablecoins into mainstream finance.
BIS Distinguishes Stablecoins From Bitcoin in Banking Impact Analysis
The BIS argues that stablecoins present a different challenge than cryptocurrencies such as Bitcoin. While Bitcoin is primarily viewed as a speculative investment, stablecoins increasingly perform functions traditionally carried out by commercial bank deposits. They are used to transfer money, settle digital asset trades, earn yield through decentralized finance applications and increasingly serve as a store of value, particularly in countries experiencing high inflation or currency instability.
The report states that every dollar converted from a commercial bank deposit into a stablecoin is money that no longer sits on a bank's balance sheet. Banks rely heavily on customer deposits because they represent one of their cheapest and most stable funding sources. Those deposits are then used to finance mortgages, corporate loans, consumer credit and countless other lending activities that support the wider economy.
According to the report, if stablecoins capture a meaningful share of household and corporate cash balances, banks may need to replace those deposits with more expensive wholesale funding. That increases funding costs, compresses profit margins and could ultimately reduce the amount of credit available to businesses and consumers.
| Traditional Bank Deposits | Stablecoins |
|---|---|
| Fund bank lending | Held outside the banking system |
| Covered by banking regulation | Issuer-dependent regulatory framework |
| Support credit creation | Generally backed by reserve assets |
| Protected by deposit insurance in many jurisdictions | Usually not covered by deposit insurance |
| Generate funding for commercial banks | Can reduce bank deposit bases if widely adopted |
The report notes that this migration could become particularly important if stablecoins evolve beyond crypto trading and become widely used for everyday payments, payroll, remittances and cross-border commerce.
The BIS stated that many stablecoin issuers invest customer reserves in short-dated U.S. Treasury bills and other highly liquid government securities. According to industry data cited in the report, issuers such as Tether and Circle have become among the largest holders of short-term U.S. Treasury securities.
BIS Supports Tokenization While Questioning Privately-Issued Stablecoins
The report makes a distinction between blockchain technology and privately issued stablecoins. Rather than rejecting blockchain technology altogether, the BIS argues that tokenization has the potential to improve settlement efficiency, reduce operational costs and simplify the movement of financial assets. The institution instead questions whether privately issued stablecoins should become the foundation of the future financial system.
Among its concerns are fragmentation between competing issuers, dependence on reserve management, financial integrity risks associated with digital wallets, and the possibility that widespread migration into stablecoins could weaken monetary sovereignty in countries with less stable domestic currencies.
Potential Impact of Large-Scale Stablecoin Adoption
| Area | Potential Effect |
|---|---|
| Commercial banks | Deposit outflows increase funding costs |
| Bank lending | Reduced capacity to extend credit |
| Government bond markets | Higher demand for Treasury securities from stablecoin reserves |
| Cross-border payments | Faster settlement and lower transfer costs |
| Consumers | Greater access to digital dollar payment systems |
The report states that the debate is becoming increasingly relevant as governments attempt to balance financial innovation with financial stability. Stablecoins were originally designed to serve cryptocurrency markets, but they are gradually becoming part of mainstream financial infrastructure, forcing central banks and regulators to consider how they fit alongside traditional deposits, payment systems and monetary policy.
