How to Prioritize Public Digital Infrastructure Over Euro-Pegged Stablecoins: A Policy Guide

Introduction

In a May 8 speech at the inaugural Banco de España LatAm Forum, European Central Bank President Christine Lagarde challenged the push for euro-denominated stablecoins. She argued that while these private digital assets serve monetary and other functions, they ultimately fall short of what the European economy needs. Instead, Lagarde called for building robust public infrastructure—like a digital euro—to ensure stability, inclusion, and sovereignty. This guide distills her message into actionable steps for policymakers, central bankers, and financial leaders seeking to navigate the future of money.

What You Need

• Understanding of stablecoin basics: Familiarity with how private digital tokens (e.g., USDC, EURT) operate, their reliance on fiat reserves, and their dual monetary/non‑monetary roles.
• Knowledge of ECB’s digital euro project: Awareness of the exploratory work, design principles, and timelines for a central bank digital currency (CBDC).
• Stakeholder buy‑in: Support from ministries of finance, regulators, commercial banks, and consumer groups to align on public infrastructure goals.
• Regulatory framework references: EU’s MiCA (Markets in Crypto‑Assets) regulation, which already sets rules for stablecoins.
• Technical expertise: Access to economists, cryptographers, and system architects who can evaluate public vs. private solutions.

Step‑by‑Step Guide

Step 1: Recognize the Dual Functions of Stablecoins

Lagarde emphasized that stablecoins perform two distinct functions: a monetary one (acting as a means of payment and store of value) and a non‑monetary one (enabling programmable transactions, smart contracts, and DeFi integration). Policy leaders must first separate these roles. Private stablecoins bundle them together, creating dependencies that can undermine public trust in the euro. Action item: Commission a white paper that analyzes both functions within your jurisdiction, noting how private issuers capture value and control.

Step 2: Assess the Risks of Euro‑Pegged Stablecoins

Drawing from Lagarde’s remarks, evaluate specific threats: financial stability (run risk if reserves are mismanaged), monetary sovereignty (loss of control over money supply), consumer protection (opaque fee structures and limited recourse), and data privacy (private databases vs. public accountability). Use scenarios—e.g., a major stablecoin depegging—to stress‑test existing safeguards. Action item: Publish a risk assessment report that ranks these threats and their probability, citing historical examples like TerraUSD’s collapse.

Step 3: Define Public Infrastructure as a Superior Alternative

Lagarde didn’t just critique stablecoins; she offered a constructive path: build public digital infrastructure. This means a central bank digital currency (CBDC) that is legal tender, programmable where needed, and designed for maximum interoperability. Unlike private stablecoins, a public euro would be backed by the ECB’s balance sheet, free of credit risk, and subject to democratic governance. Action item: Outline the core attributes of your proposed public infrastructure: instant settlement, offline capability, privacy protections (not anonymity), and integration with existing payment systems.

Step 4: Engage in Multi‑Stakeholder Collaboration

Effective public infrastructure requires input from diverse actors. Lagarde’s forum speech highlighted the need for dialogue between Europe and Latin America—but the same applies domestically. Action item: Form an advisory council comprising central bankers, commercial lenders, fintech innovators, consumer advocates, and privacy experts. Hold public consultations to gather feedback on design trade‑offs (e.g., interest‑bearing vs. non‑interest‑bearing digital tokens). This builds legitimacy and reduces pushback from incumbents.

Step 5: Pilot and Iterate Before Full Rollout

Lagarde warned against hasty moves; stablecoins often launch with insufficient testing. Public infrastructure should follow a phased approach. Action item: Launch a limited pilot—perhaps for interbank settlement first—before expanding to retail use. Measure performance against key metrics: transaction speed, energy consumption, user adoption, and resilience to cyber attacks. Use feedback loops to refine the platform. The ECB’s own two‑year investigation phase for the digital euro (2021‑2023) serves as a model.

Step 6: Establish Clear Regulatory Guardrails

Even with public infrastructure in place, private stablecoins may still exist. Lagarde’s position implies that they should be regulated, not banned, but not treated as a substitute for public money. Action item: Update MiCA or create complementary regulation that: (a) imposes strict reserve requirements on euro‑pegged stablecoins, (b) mandates full transparency of reserves, (c) limits stablecoin usage to non‑monetary functions (e.g., tokenization of assets) where possible, and (d) ensures that only the public digital euro enjoys legal‑tender status.

Step 7: Communicate the Vision to the Public

Finally, no infrastructure succeeds without public trust. Lagarde’s speech was itself a communication tool—making the case for why stablecoins are not the answer. Action item: Launch a public awareness campaign explaining why a digital euro is safer and more equitable than private stablecoins. Use plain language, analogies (e.g., “public roads vs. private toll roads”), and testimonials from early pilot users. Address common concerns about surveillance and privacy directly.

Tips for Success

• Don’t fall for the “fast money” trap: Private stablecoins may promise quick integration with DeFi, but public infrastructure is a marathon. Prioritize long‑term stability over short‑term convenience.
• Learn from global examples: Study China’s digital yuan pilot, Nigeria’s eNaira, and the Bahamas’ Sand Dollar—but also note their challenges, such as low adoption or surveillance fears.
• Keep interoperability in mind: Public infrastructure must work seamlessly with existing payment systems (SEPA, TARGET2) and with other CBDCs to avoid fragmentation.
• Embrace programmability cautiously: While smart‑money features are attractive, they introduce complexity and potential for misuse. Start with basic programmable payments (e.g., conditional transfers) before advancing.
• Budget for continuous innovation: Digital money evolves fast. Allocate funding not just for the launch, but for ongoing upgrades, security audits, and user education.
• Maintain a fallback plan: If public infrastructure faces technical failures or low uptake, ensure that traditional fiat systems remain robust as a backstop.

By following these steps, policymakers can heed Lagarde’s advice: instead of relying on private stablecoins that serve narrow interests, invest in public digital infrastructure that serves the entire European economy.
