ECB’s Lagarde Warns Europe Against Rushing Into Euro-Denominated Stablecoins

TLDR:

• Nearly 98% of stablecoins are dollar-denominated, leaving the euro with minimal global digital presence.
• USD Coin fell to $0.877 after SVB’s collapse, showing stablecoins can break their one-dollar peg.
• Eurosystem’s Pontes project will settle DLT transactions in central bank money from September 2026.
• Lagarde says deeper EU capital markets, not stablecoins, are the key to strengthening the euro’s role.

Stablecoins have grown from under USD 10 billion six years ago to more than USD 300 billion today. ECB President Christine Lagarde addressed this growth at the Banco de España LatAm Economic Forum on May 8, 2026.

She urged policymakers to separate the monetary and technological functions of stablecoins before acting. Her remarks challenged growing calls for Europe to develop competing euro-denominated alternatives.

ECB Chief Separates Two Functions Often Conflated in the Stablecoin Debate

Lagarde opened by pointing to the concentration within the stablecoin market. Nearly 90% of it is controlled by just two issuers: Tether and Circle.

Tether is based in El Salvador, while Circle operates from the United States. Close to 98% of all stablecoins are denominated in US dollars, leaving the euro with minimal presence.

The US GENIUS Act has pushed the debate further by framing stablecoins as a tool for dollar dominance. Proponents argue that Europe risks digital dollarisation without a euro stablecoin strategy.

Lagarde, however, questioned this framing directly at the Forum. She argued that the debate has not asked clearly enough what stablecoins are actually for.

She drew a distinction between two separate functions that stablecoins perform. One is monetary, extending the reach of reserve currencies across borders.

The other is technological, providing a settlement asset for distributed ledger platforms. These two functions, she said, are being conflated in the current policy conversation.

To anchor her point, Lagarde cited the Roman philosopher Seneca. “To one who does not know which port one is sailing to, no wind is favourable,” she quoted.

Europe must first identify its objectives before choosing its instruments. Adopting stablecoins without that clarity, she warned, risks importing fragilities rather than building new strengths.

Financial Stability and Monetary Policy Risks Weigh Against Euro Stablecoins

Euro-denominated stablecoins could, in theory, expand global demand for euro area safe assets. This would compress sovereign yields and ease financing conditions in the short term.

However, Lagarde pointed to two material trade-offs attached to this path. Both relate to financial stability and the transmission of monetary policy.

On financial stability, she referenced the March 2023 Silicon Valley Bank collapse. Circle disclosed at the time that USD 3.3 billion of USD Coin’s reserves were held there.

USD Coin fell briefly to USD 0.877, trading well below its one-dollar peg. At scale, such episodes can trigger mass redemptions and stress underlying asset markets rapidly.

On monetary policy, deposit migration to stablecoins narrows the credit channel through banks. When retail deposits shift into non-bank stablecoins, they return to banks only as wholesale funding.

ECB research found that this reduces lending to firms and weakens policy rate pass-through. In the euro area, where banks dominate credit provision, this effect is especially pronounced.

Given these trade-offs, Lagarde argued that stablecoins are not an efficient route to strengthening the euro’s international role. The better path, she said, remains deeper and more integrated capital markets.

The savings and investments union, combined with a stronger euro safe asset base, offers a more durable solution. These structural priorities must come before any euro stablecoin strategy.

Eurosystem Builds On-Chain Settlement Infrastructure to Anchor Tokenised Finance

Despite her reservations, Lagarde acknowledged that the technology behind stablecoins carries genuine value. Distributed ledger technology can integrate Europe’s highly fragmented financial market infrastructure.

In 2023, the EU operated 295 trading venues, 14 clearing counterparties, and 32 central securities depositories. The United States, by comparison, runs two clearing houses and a single central securities depository.

The Eurosystem is building public infrastructure to address this fragmentation directly. From September 2026, the Pontes project will connect distributed ledger platforms to TARGET, the Eurosystem’s existing settlement system.

This allows DLT-based transactions to settle in central bank money from day one. Pilot tests in 2024 covered 50 transactions across nine jurisdictions, settling around EUR 1.6 billion.

The Appia roadmap, published in March 2026, targets a fully interoperable European tokenised financial ecosystem. The framework is scheduled for completion by 2028.

Once central bank money is natively available on-chain, market participants gain a credible euro-anchored alternative. This reduces default reliance on dollar-denominated private stablecoins across European tokenised markets.

Tokenised commercial bank deposits also emerged as a potential complement in Lagarde’s remarks. These carry the credit quality of regulated institutions and can circulate on distributed ledger platforms.

They may prove preferable to stablecoins for many wholesale use cases over time. The Eurosystem’s infrastructure is designed to support all such instruments within a safe and interoperable framework.
