TLDR
- The European Central Bank said rising stablecoin use may reduce retail bank deposits in the euro area.
- ECB staff found that stablecoin adoption is linked to lower lending to firms.
- The working paper said banks may rely more on wholesale funding if deposits decline.
- The report stated that stablecoins can interfere with monetary policy transmission channels.
- The impact of stablecoin growth varies by adoption scale, design, and regulation.
The European Central Bank has warned that rising stablecoin use could weaken bank lending and monetary policy transmission in Europe. In a new working paper, ECB staff linked growing stablecoin adoption to lower retail deposits and reduced corporate lending. The report said expanding digital asset use may interfere with how policy rates influence bank funding and credit supply.
Stablecoins and the Deposit Substitution Effect
The ECB released its working paper titled “Stablecoins and Monetary Policy Transmission” on Tuesday. The authors examined how stablecoins affect bank deposits and credit flows across the euro area. They found that higher stablecoin interest links to measurable declines in retail bank deposits.
The paper described a deposit substitution effect driven by households and firms. Customers move funds from traditional deposits into digital tokens pegged to major currencies. As a result, banks lose a stable and low-cost funding source for lending.
The authors stated, “Banks rely heavily on deposits as a stable and low-cost source of funding.” They added that falling deposits push banks toward wholesale funding markets. Such funding usually costs more and carries higher volatility.
The paper also assessed how policy rates pass through the banking system. It found that stablecoin growth can alter bank funding costs and lending behavior. The impact varies with adoption scale, token design, and regulatory treatment.
ECB staff wrote, “We find that stablecoin adoption interferes with multiple monetary policy transmission channels.” They said this interference may weaken the predictability of policy actions. The effects appear nonlinear and depend on market structure.
Dollar-Backed Tokens Dominate Market Growth
The ECB placed its findings within the context of rapid market expansion. Stablecoin market capitalization has more than doubled over the past three years. The report cited projections that the market could reach $2 trillion by 2028.
Data referenced in the paper showed strong dominance by US dollar-backed tokens. CoinGecko data indicated dollar-pegged tokens account for $301 billion in value. This figure represents about 97% of the total stablecoin market capitalization.
The ECB warned that foreign-currency stablecoins could weaken domestic policy links. When non-euro tokens dominate, domestic monetary policy may lose influence over lending conditions. The paper said this risk increases as cross-border usage expands.
ECB officials have previously raised concerns about dollar-denominated tokens. They said widespread dollar stablecoin use could affect monetary sovereignty in the euro area. Officials also questioned the euro’s role in cross-border payments.
