Can Europe Adopt Stablecoins?

European regulators approved the Markets in Crypto-Assets regulation, known as MiCA, in 2023 to create a legal framework for stablecoins. The European Central Bank and banks are testing how fiat-backed tokens might operate alongside a potential digital euro and existing payment systems.

MiCA defines two main token types: e-money tokens backed one-for-one by a currency, and asset-referenced tokens backed by a mix of assets. The rules require issuers to hold transparent reserves, meet capital and governance standards, provide redemption rights to holders and accept supervision from national regulators and, for larger providers, the European Securities and Markets Authority.

Market use of stablecoins in Europe is largely driven by global issuers and crypto trading platforms. Tokens such as USDT and USDC are used by institutional and retail users for trading, settlement and cross-border transfers, mainly on private crypto rails rather than through bank settlement systems. Some banks and payments firms are developing tokenised deposits and custody services to connect fiat-backed tokens with traditional settlement systems. Fintech companies are building wallets and on-ramps that combine identity checks and anti-money-laundering controls with token custody.

European authorities have identified several risks linked to stablecoins. Regulators have raised concerns about the possibility of rapid redemptions if holders lose confidence, the potential for deposits to move away from banks, and effects on monetary policy transmission if private tokens reach large scale. The 2022 failure of an algorithmic stablecoin increased scrutiny of tokens that rely on complex market mechanisms rather than direct asset backing. Policy responses since then have emphasized reserve transparency, access to reliable liquidity and clear recovery plans for issuers.

Technical and market infrastructure also present challenges. Issuers must keep reserves in liquid, creditworthy assets and arrange independent audits of those reserves. Interoperability between token platforms and bank settlement systems remains limited. Custody standards for private keys and the ability to process large-value redemptions quickly are open issues. Payments firms and exchanges are working on integrations with real-time settlement networks, but full-scale links with legacy payment rails require coordination between private firms and public authorities.

MiCA creates a route for onshore issuance of fiat-backed tokens but also adds compliance costs. Some issuers will need to obtain licences as electronic money institutions or set up EU-based entities that meet governance and capital requirements. Those requirements could influence which firms choose to offer tokens in the EU. Cross-border coordination with non-EU jurisdictions and international standard-setting bodies will affect how global stablecoin issuers operate in Europe.

The ECB has published analysis on a central bank digital currency, often called a digital euro, and on how it could interact with private stablecoins. The ECB has described a digital euro as a public option for digital money that preserves monetary policy and financial stability. The technical design, access rules for commercial banks and settlement and privacy features would shape how a digital euro and regulated private stablecoins coexist.

Adoption factors cited by market participants include consumer trust, merchant acceptance, availability of regulated on- and off-ramps, user experience, fees to convert tokens to bank deposits and merchant integration. Institutional users such as asset managers and corporate treasuries are evaluating stablecoins for faster settlement and cross-border liquidity, while banks are assessing custody models and partnership arrangements.

Background: Stablecoins are digital tokens meant to keep a stable value relative to a fiat currency or a basket of assets. They include fiat-backed tokens that hold reserves in currency or short-term government debt and algorithmic versions that use market mechanisms to maintain value. High-profile failures of algorithmic stablecoins in 2022 led regulators worldwide to strengthen oversight. MiCA sets prudential rules, market conduct standards and governance requirements for stablecoin issuance within the EU.
