ECB President Lagarde: Why Public Digital Infrastructure Trumps Stablecoins

In a speech at the inaugural Banco de España LatAm Forum on May 8, European Central Bank President Christine Lagarde delivered a clear message: euro-pegged stablecoins are not the solution for Europe's digital currency future. Instead, she advocated for building robust public infrastructure, such as a central bank digital currency (CBDC). This Q&A breaks down her key arguments, the risks of stablecoins, and the rationale behind the ECB's push for a digital euro.

What exactly did Lagarde say about stablecoins at the forum?

Lagarde criticized the development of stablecoins pegged to the euro, arguing they serve two distinct functions: a monetary function by extending a form of private money, and a payment function. She warned that these private digital currencies could undermine monetary sovereignty and financial stability if not properly regulated. Rather than relying on private stablecoins, she urged policymakers to focus on creating public digital infrastructure—namely, a central bank digital currency (CBDC) like the digital euro. This approach ensures that the state retains control over monetary policy and that the system remains resilient, inclusive, and secure for all Europeans. Her remarks align with the ECB's ongoing exploration of a digital euro as a safer, publicly backed alternative.

Why does Lagarde believe stablecoins are not the answer?

According to Lagarde, stablecoins pose several fundamental risks. First, they blur the line between money and financial assets, potentially creating systemic vulnerabilities if these private tokens were to become widely adopted. Second, they operate outside traditional regulatory frameworks, making oversight difficult and exposing users to fraud, operational failures, and runs. Third, stablecoins could fragment the single currency area if different issuers launch competing euro-pegged tokens, each with varying levels of backing and trust. Finally, Lagarde stressed that private stablecoins lack the ultimate backstop of a central bank, meaning they cannot guarantee redemption at par in times of stress. For these reasons, she concluded that relying on stablecoins is a risky gamble compared to building publicly controlled digital payment infrastructure.

What did Lagarde identify as the two functions of stablecoins?

Lagarde broke down stablecoins into two core functions: a monetary function and a payment function. The monetary function refers to stablecoins acting as a form of money—a store of value and unit of account—pegged to a fiat currency like the euro. This gives them the potential to replace traditional money in everyday transactions. The payment function, on the other hand, involves using stablecoins as a medium for transferring value quickly and cheaply across borders. However, Lagarde argued that these functions are better served by public infrastructure. A digital euro, for example, would deliver the same monetary stability as cash while offering the payment efficiency of modern digital systems—without the risks associated with private issuers.

How does Lagarde propose building public infrastructure instead?

The ECB president advocated for prioritizing the development of public digital payment infrastructure, centered around a digital euro. This is not just a token but a comprehensive system comprising a central bank-issued digital currency that would be accessible to all citizens and businesses. Key elements include ensuring offline functionality, strong privacy protections, and seamless integration with existing banking systems. Lagarde envisions the digital euro as a complement to cash, not a replacement, and emphasizes that it would be built on European values—public oversight, financial inclusion, and resilience. She also called for investment in back-end infrastructure, such as a unified European payment system, to reduce reliance on foreign tech giants and private stablecoins.

What risks of stablecoins did Lagarde highlight specifically for the euro area?

Lagarde pointed to several euro-area-specific risks. One major concern is the potential for stablecoins to disrupt monetary policy transmission. If significant volumes of euro-denominated stablecoins circulate outside the regulated banking system, the central bank's ability to influence interest rates and credit conditions could weaken. Another risk is financial fragmentation: different euro-pegged stablecoins with varying levels of trust could create a de facto multi-currency system within the eurozone, undermining the single currency's integrity. Additionally, she warned about the risk of disintermediation, where stablecoin issuers might bypass traditional banks, leading to instability and reduced credit availability. Finally, Lagarde cited the risk of regulatory arbitrage, as stablecoin issuers often operate across borders, making it difficult for national authorities to enforce rules.

How does the ECB's digital euro proposal address the concerns Lagarde raised?

The digital euro directly addresses each of Lagarde's concerns. As a liability of the central bank, it would offer the same safety as cash, eliminating credit and liquidity risks associated with private stablecoins. It would be universally accepted across the eurozone, ensuring monetary unity rather than fragmentation. The digital euro would also be designed to protect privacy and prevent surveillance by either the central bank or private entities. Crucially, the ECB plans to cap individual holdings to avoid disintermediation of banks—users could hold only a limited amount, with excess flows returning to the banking system. The infrastructure would be public, resilient, and regulated under a unified framework, reducing the risk of regulatory arbitrage. In short, the digital euro is intended to provide the benefits of modern digital payments without the systemic dangers of private stablecoins.

What was the context of Lagarde's speech at the Banco de España LatAm Forum?

Lagarde delivered her remarks on May 8 at the inaugural Banco de España LatAm Forum, an event focused on financial innovation and cooperation between Europe and Latin America. The forum provided a platform for central bankers and policymakers to discuss emerging trends in digital finance, including cryptocurrencies, stablecoins, and CBDCs. Lagarde used the opportunity to reinforce the ECB's stance that while innovation is welcome, it must not come at the expense of stability and sovereignty. Her speech specifically targeted the growing interest in euro-pegged stablecoins, which have been proposed by various private entities seeking to capitalize on demand for digital euro-like instruments. By choosing this forum, she aimed to signal to both European and Latin American audiences that public infrastructure—not private tokens—should lead the way in modernizing the financial system.
