| What to Know: – Stablecoins displace bank deposits, tightening funding and constraining credit supply. – Reserve liquidations during runs spread stress into money markets and banks. – Monetary policy transmission weakens as deposits migrate into nonbank stablecoin platforms. |
According to the ECB Financial Stability Review (November 2025), stablecoins are an emerging channel of risk to euro-area bank lending. The review highlights deposit displacement from banks, spillovers via reserve liquidations, and potential weakening of monetary policy transmission. If deposits migrate, lenders could face tighter funding conditions and a smaller capacity to extend credit.
Stablecoin pegs are maintained by reserves such as short-term government securities, repo positions, and bank deposits. In a stablecoin run or de-peg, issuers may need to sell reserves rapidly, transmitting stress into money markets and back to banks. According to the Bank for International Settlements, these instruments perform poorly on elasticity and integrity relative to central bank money, making them fragile under stress. Design matters: fully reserved tokens can transmit stress through reserve fire-sales, while algorithmic setups risk outright peg failures.
Deposit disintermediation occurs when households and firms shift cash from banks into stablecoins or platforms that wrap bank-like claims. As core deposits shrink, banks may replace them with wholesale or secured funding at higher spreads, compressing net interest margins and restraining loan growth. As reported by MLex, research indicates that deposits linked to stablecoin activity can be less stable and, when holder identity is opaque, may weaken banks’ liquidity and capital positions.
The central bank’s leadership is pressing for safeguards on foreign stablecoins to prevent regulatory arbitrage and protect financial stability. “Stablecoins should comply with EU standards before operating on EU soil,” said Christine Lagarde, the central bank’s president.
A further structural risk is euro-area reliance on dollar-denominated stablecoins. If users prefer USD tokens for payments or yield, euro liquidity can be bypassed, complicating policy transmission and narrowing banks’ role in deposit-taking and maturity transformation.
Scale still matters. The review noted that global stablecoins outstanding were around USD 290 billion and remain small relative to the banking system, yet interconnectedness with traditional finance stands out as a vulnerability. Monitoring redemptions, reserve composition, and bank funding spreads will be critical as adoption evolves.
