ECB Warns of Stablecoin Impact on Bank Deposits and Monetary Policy

The European Central Bank (ECB) has raised concerns about the increasing use of stablecoins and its potential impact on traditional banking systems. According to Cointelegraph, a new ECB working paper released Tuesday highlights that the growing adoption of stablecoins, which are digital assets often pegged to currencies like the US dollar or euro, could draw funds away from traditional bank deposits. This shift may weaken the transmission of monetary policy through lending channels. The ECB's analysis indicates a measurable decline in retail bank deposits and a reduction in lending to firms as interest in stablecoins rises. The report suggests that stablecoins could reduce the amount of credit banks provide to the real economy. The effects of stablecoin adoption are described as nonlinear, varying based on the scale of adoption, design features, and regulatory frameworks. This report is part of the ECB's ongoing efforts to monitor stablecoins, whose market capitalization has surged over the past three years to $312 billion and is projected to reach $2 trillion by 2028. In examining the impact on banks, the ECB identified a deposit-substitution effect, where households and firms shift funds from retail bank deposits to digital assets. The study notes that banks heavily rely on deposits as a stable and low-cost funding source to support lending to households and businesses. A decline in deposits could force banks to depend more on wholesale or market-based funding, which is typically more expensive and less stable. The report also highlights that stablecoins can alter how policy interest rates affect bank funding costs and lending, with impacts varying by adoption scale, design, and regulation. The ECB warns that stablecoin adoption could interfere with multiple monetary policy transmission channels, potentially weakening the predictability of policy actions. Additionally, the central bank cautions that foreign-currency stablecoins could further weaken the connection between domestic monetary policy and bank lending, with risks amplified when the market is dominated by non-euro-denominated tokens. The study reiterates that US dollar-backed stablecoins constitute the vast majority of the stablecoin market. Data from CoinGecko shows these dollar-pegged tokens are valued at $301 billion, representing 97% of the total stablecoin market capitalization at the time of publication.
