Stablecoin related to the dollar, it is alarm: ECB and EU institutions warn on global risks

The European Central Bank (ECB) and other EU institutions have raised significant concerns about the global risks posed by U.S. dollar-backed stablecoins, such as Tether (USDT) and USD Coin (USDC), which dominate the $255 billion stablecoin market, with 99.8% of stablecoin activity in Europe tied to the U.S. dollar. These warnings center on threats to monetary sovereignty, financial stability, and the euro’s global role, prompting calls for regulatory action and the accelerated development of a digital euro. Below is a detailed analysis of the issue, incorporating insights from recent reports and posts on X, as of July 7, 2025.

Key Concerns About U.S. Dollar Stablecoins

  1. Erosion of Monetary Sovereignty:
  • The ECB, led by President Christine Lagarde and Chief Economist Philip Lane, warns that widespread adoption of USD-backed stablecoins in Europe could lead to “digital dollarization.” If European consumers and businesses increasingly use dollar-based stablecoins for payments or savings, the ECB’s ability to control monetary policy—such as setting interest rates or managing inflation—could be undermined. This is because transactions would be anchored to the U.S. dollar, reducing the euro’s role as the primary medium of exchange.
  • Lorenzo Bini Smaghi, former ECB board member and Société Générale chairman, emphasized that the euro’s near absence from the stablecoin market (less than 1% share) risks marginalizing Europe in the digital economy, potentially diverting capital to U.S.-linked platforms.
  1. Financial Stability Risks:
  • The ECB highlights the risk of a “run” on stablecoins, where a loss of confidence in a stablecoin’s issuer (e.g., due to insolvency or collateral devaluation) could trigger mass redemptions, destabilizing financial systems. This is particularly concerning given that 80–90% of major stablecoins like USDT and USDC are held by large investors (e.g., crypto funds, hedge funds), whose actions could amplify market shocks.
  • A specific concern is the fungibility of stablecoins issued under multiple jurisdictions (e.g., USDC under U.S. rules and the EU’s MiCA regulation). If U.S. holders attempt to redeem EU-issued stablecoins during a crisis, EU reserves could be strained, risking financial contagion. The ECB notes that EU issuers must hold reserves in EU banks to meet redemption demands, but cross-border redemption could complicate this.
  1. Capital Outflows and U.S. Debt Dependency:
  • USD stablecoins are primarily backed by U.S. Treasuries, meaning their adoption in Europe channels European savings into U.S. debt markets. The ECB fears this could weaken the euro’s international standing and increase Europe’s exposure to U.S. economic shocks.
  • The European Stability Mechanism (ESM) and ECB argue that reliance on U.S. payment infrastructure (e.g., through stablecoins integrated by firms like Bank of America or Circle) could entrench dollar dominance in European finance.
  1. Regulatory and Competitive Challenges:
  • The EU’s Markets in Crypto-Assets (MiCA) regulation, fully implemented in January 2025, imposes strict rules on stablecoin issuers, requiring EU-based reserves and supervisory clearance for e-money tokens (EMTs). However, the ECB argues MiCA may not be robust enough to counter the “turbocharged” U.S. stablecoin industry, especially after U.S. policies under the Trump administration (e.g., the GENIUS Act) eased stablecoin adoption.
  • The European Commission and ECB have clashed over MiCA’s adequacy. The Commission believes MiCA’s safeguards—such as a €200 million daily transaction limit for foreign stablecoins in mainstream payments—are sufficient, while the ECB calls for urgent amendments to address dollarization risks.

EU and ECB Responses

  1. Push for a Digital Euro:
  • The ECB is accelerating its digital euro project to counter USD stablecoin dominance. ECB officials like Philip Lane and Pierre Gramegna (ESM) argue that a central bank digital currency (CBDC) would preserve monetary sovereignty by offering a euro-based alternative for digital payments. The digital euro is seen as a defense against dollarization and a way to enhance Europe’s financial autonomy.
  • However, the European Parliament has delayed voting on the digital euro package, reflecting skepticism about its advantages over private stablecoin solutions. Some argue that a CBDC may overlap with euro-backed stablecoins without clear benefits.
  1. Strengthening MiCA Regulations:
  • MiCA requires stablecoin issuers to back tokens with cash and high-quality sovereign debt, hold reserves in EU banks, and comply with capital and transparency rules. It also allows regulators to intervene if a stablecoin threatens monetary sovereignty. The Commission is set to clarify that EU-licensed stablecoins (e.g., USDC issued under MiCA) are interchangeable with non-EU versions, but with re-balancing mechanisms to ensure EU reserves match EU holdings.
  • Despite these safeguards, the ECB warns that MiCA’s carve-out for crypto transactions (no €200 million limit) and exemptions for certain financial transactions (e.g., stock market settlements) could allow USD stablecoins to dominate.
  1. Promoting Euro Stablecoins:
  • Bini Smaghi and others urge European banks to issue euro-backed stablecoins to compete with USD stablecoins. MiCA provides regulatory clarity, but European banks remain cautious due to perceived risks, regulatory complexity, and reputational concerns. Initiatives like the ECB-approved Pontes Appia blockchain project signal growing acceptance of euro-based digital assets.
  • The EU is also experimenting with tokenized securities (e.g., Slovenia’s tokenized sovereign bond) to integrate blockchain into public infrastructure, fostering euro-based digital finance.

Critical Perspective

The ECB’s warnings about USD stablecoins reflect legitimate concerns about monetary sovereignty and financial stability, but their “alarmist” tone, as noted by the European Commission, may exaggerate risks to push the digital euro agenda. MiCA’s €200 million transaction cap and reserve requirements provide robust protections, and the Commission argues that a run on a well-governed stablecoin is “very unlikely.” The ECB’s focus on dollarization risks overlooks the fact that stablecoins primarily serve crypto markets, with limited mainstream payment adoption in Europe. Critics, including some X posts, suggest the ECB’s push for a digital euro is more about centralizing control than addressing immediate threats.
Conversely, the U.S.’s embrace of stablecoins (e.g., via relaxed regulations for banks) strengthens the dollar’s global role, potentially at Europe’s expense. The lack of euro stablecoins reflects not just regulatory caution but also a failure to incentivize innovation, leaving Europe lagging in a $255 billion market.
