The European Central Bank (ECB) has voiced strong reservations about the expansion of euro stablecoins, warning that they could undermine financial stability and weaken the effectiveness of monetary policy. ECB President Christine Lagarde, along with other central bankers, highlighted these risks during discussions with EU finance ministers in Cyprus. These warnings come amid proposals from a Brussels-based think tank suggesting relaxed regulations for crypto issuers to promote a European stablecoin market.
Stablecoins are digital currencies pegged to traditional fiat currencies like the euro or US dollar. They are widely used for cross-border payments and within the cryptocurrency ecosystem due to their price stability. The global stablecoin market has surged from about $10 billion six years ago to over $300 billion today, with most tied to the US dollar. European policymakers are exploring ways to foster euro-denominated stablecoins to reduce dependence on dollar-based products.
The ECB’s scepticism centers on two main issues: threats to financial stability and the potential disruption of monetary policy transmission. A key concern is that if depositors move funds from traditional bank accounts into stablecoins, banks would lose stable funding sources. This shift could force banks to rely more on costly wholesale funding, reducing their ability to lend effectively to businesses and households. In the eurozone, where banks dominate credit provision, this could significantly weaken the ECB’s control over interest rates.
Financial stability risks arise because stablecoins are private liabilities backed by reserve assets whose value depends on market confidence. Any loss of trust can trigger rapid redemption demands, potentially causing instability. Lagarde pointed to the collapse of Silicon Valley Bank in 2023 as an example, when reserves backing a major stablecoin were held at the bank, causing the token’s value to briefly drop below its guaranteed level.
In a May 2026 speech, Lagarde clarified that stablecoins serve two different roles: a monetary function and a technological one. While euro stablecoins might increase demand for European government bonds in the short term, she argued that the risks outweigh these benefits. On the technology side, distributed ledger technology (DLT) offers advantages for transaction settlement but private stablecoins lack the absolute finality guaranteed by central bank money.
Instead of promoting private stablecoins, Lagarde advocates for tokenised commercial bank deposits, which combine regulatory security with blockchain efficiency. The ECB is developing its own infrastructure project named Pontes to connect DLT platforms with existing settlement systems by September 2026, enabling transactions settled directly in central bank money.
The ECB’s cautious stance contrasts with industry initiatives such as Qivalis—a consortium of 37 European banks aiming to launch a euro stablecoin this year—and ongoing revisions of EU crypto regulations like MiCAR. While some policymakers favor easing rules to support market growth, ECB officials remain concerned about risks posed by private stablecoins and resist proposals for the ECB to act as a lender of last resort for these issuers.
Overall, the ECB emphasizes strengthening Europe’s capital markets and expanding safe government bond issuance as more sustainable paths to bolster the euro’s international role rather than relying on potentially destabilizing private digital currencies.
