Euro Stablecoins and Regional Variants

While the majority of stablecoins are pegged to the US dollar, the cryptocurrency market has increasingly developed stablecoins targeting other currencies and regions. This chapter explores the emergence of euro stablecoins, stablecoins for other major currencies, and how regional economic dynamics affect stablecoin adoption and utility.

The Case for Non-USD Stablecoins

The dominance of USDT and USDC reflects both the US dollar's global prominence and the historical accident that these were the first widely adopted stablecoins. However, compelling reasons support the development of stablecoins pegged to other currencies.

Currency Risk and User Preferences

Parties in the Eurozone, United Kingdom, Japan, and other regions face a problem: holding their wealth in USD-denominated stablecoins creates currency risk. If the euro strengthens against the dollar, euro holders lose purchasing power on their stable coin holdings.

A user in Germany earning euros from employment would prefer to hold euros, even in stablecoin form, rather than being forced to hold dollars. Euro stablecoins allow euro users to participate in cryptocurrency markets while maintaining their preferred currency.

Regulatory and Monetary Policy Preferences

Different regions have different monetary policy and regulatory frameworks. The European Central Bank (ECB) has different inflation targets, interest rate policies, and regulatory approaches compared to the Federal Reserve.

Some users and institutions prefer to maintain exposure to euro monetary policy rather than dollar monetary policy. Euro stablecoins allow this preference.

Emerging Market and Currency Instability

In countries with unstable local currencies (Turkey, Argentina, Venezuela, Nigeria), the appeal of a stablecoin pegged to a stable currency is obvious. But if a user's local currency is in crisis, they might prefer a euro or even another emerging market currency to the dollar for geographic or political reasons.

Stablecoins pegged to multiple currencies expand the options available to users in high-inflation or unstable currency environments.

Major Euro Stablecoins

Several euro stablecoins have been developed, though none has achieved the market dominance of USDT or USDC.

EUROC (Circle)

Circle, the issuer of USDC, also issues EUROC, a stablecoin pegged to the euro. Like USDC, EUROC is full-reserve backed and audited.

EUROC launched in 2023 and initially found adoption in Europe, where Circle has European regulatory approval.

Key characteristics:

• Full reserve backing in euros
• Regulated by European authorities
• Available on major exchanges with euro trading pairs
• Integration with European fintech platforms

However, EUROC has not achieved the market penetration of USDC (denominated in dollars). The total supply of EUROC is substantially smaller than USDC.

EURT (Tether)

Tether, in addition to USDT, also issues EURT (euro-denominated). Like USDT, EURT claims full reserve backing but provides limited reserve transparency.

EURT is available on major exchanges and has modest adoption, particularly in Europe.

However, EURT has not achieved the market leadership in euros that USDT enjoys in dollars.

Wrapped Euro Stablecoins and Bridges

Some platforms offer euro stablecoins through wrapped or bridged mechanisms rather than direct issuance. These include:

• EURS (a euro stablecoin issued by Stasis)
• Sora (a synthetic euro developed by research protocols)
• Various layer-2 versions of USDC and USDT with synthetic euro pairs

These alternatives have limited adoption compared to direct issuers like Circle and Tether.

Market Dynamics: Why Dollar Dominance Persists

Despite the theoretical case for euro stablecoins, USDT and USDC continue to dominate even in European and non-dollar markets. Several factors explain this:

Network Effects and Liquidity

Dollar stablecoins have deeper liquidity and more trading pairs. On most exchanges, the USDC-USD pair or USDT-USD pair has the highest volume. Euro pairs have significantly lower volume.

This liquidity advantage means users can convert between stablecoins and other cryptocurrencies more efficiently using dollar stablecoins.

Established Infrastructure

Billions of dollars of DeFi infrastructure has been built around USDC and USDT. Lending protocols, trading venues, payment systems, and other applications primarily support dollar stablecoins.

Building euro stablecoin infrastructure requires duplicating this work, which is expensive and time-consuming.

The Dollar's Continued Global Dominance

The US dollar remains the world's dominant reserve currency. International trade, commodities, and cross-border finance overwhelmingly operate in dollars.

Users in euro regions may still prefer to hold dollars for international business, even if they would prefer euros for local purposes.

Exchange Rate Arbitrage

Interestingly, some euro-area users actually prefer holding dollar stablecoins if they believe the euro will weaken. In periods of euro weakness, dollar stablecoins provide a hedge.

This creates demand for dollar stablecoins even among euro users—an effect that actually suppresses demand for euro stablecoins.

Stablecoins in Emerging Markets

Beyond major currencies, stablecoins pegged to emerging market currencies have emerged.

Brazilian Real Stablecoins

Brazil has developed several stablecoins pegged to the Brazilian real, including BRLU and others. These are used in Brazilian DeFi and provide alternatives to dollar stablecoins for Brazilian users.

However, these remain niche compared to USDT and USDC.

Southeast Asian Stablecoins

Singapore, Thailand, and other Southeast Asian countries have developed local stablecoin initiatives, sometimes with central bank involvement. These have seen more success than purely private stablecoins in other emerging markets.

The Central Bank Digital Currency (CBDC) Question

Most central banks, including the ECB and Federal Reserve, are exploring central bank digital currencies (CBDCs). If and when CBDCs are deployed, they could subsume private stablecoins in their respective regions.

A euro CBDC, for example, might reduce the need for private euro stablecoins by providing a direct digital euro issued by the ECB.

However, CBDCs are still in testing phases, and their deployment is years away. Until then, private stablecoins remain the primary mechanism for digital currency functionality.

Multi-Currency and Synthetic Stablecoins

Some protocols have experimented with stablecoins pegged to baskets of currencies rather than single currencies.

Reserve Protocol

Reserve is a protocol that attempts to create a stablecoin pegged to a basket of currencies and commodities. The idea is to create a unit of account that is stable against the global economy rather than dependent on a single currency.

However, baskets introduce complexity: they require constant rebalancing, they are less intuitive for users (who prefer single-currency targets), and they create additional risk vectors.

Basket stablecoins have not achieved significant adoption.

Gold-Backed and Commodity Stablecoins

Some projects have created stablecoins backed by physical commodities like gold or oil. These combine the benefits of stablecoins (liquidity, programmability) with commodity diversification.

However, commodity backing introduces new risks: storage, insurance, theft, quality verification. The added complexity has limited adoption.

Regulatory Frameworks for Multi-Currency Stablecoins

Regulators in the EU and other regions are developing specific frameworks for non-USD stablecoins.

MiCA (Markets in Crypto Assets Regulation)

The European Union's MiCA regulation, effective from 2024, treats stablecoins as a regulated asset class. The framework applies to any stablecoin operating in the EU, regardless of base currency.

Key provisions:

• Significant stablecoins (more than 500 million euros in market cap) face stringent requirements including prudential requirements and supervision.
• Issuers must maintain full backing and prove it regularly.
• Issuers must be authorized under financial regulation.
• There are prohibitions on extending credit using stablecoins.

MiCA applies equally to USDC, USDT, EUROC, and other stablecoins, but creates a more favorable framework for euro-denominated stablecoins issued by EU-regulated entities.

Swiss and UK Approaches

Switzerland and the UK have also developed stablecoin regulation allowing private issuance under licensing requirements. These frameworks are less restrictive than MiCA but still require demonstrable backing and regular verification.

The Role of Stablecoins in Cross-Border Payments

One major potential application for multi-currency stablecoins is cross-border payments.

Traditional Cross-Border Payment Problems

Currently, sending money internationally is expensive and slow. A bank transfer from the US to Europe can take days and cost 2-5% in fees. Money remittance services (like Western Union) charge even higher fees but offer faster delivery.

Stablecoins potentially offer an alternative: send USDT from New York to London in minutes for negligible fees, then convert to sterling locally.

The Forex Pair Problem

However, for this to work at scale, the recipient needs to be able to convert stablecoins to local currency efficiently. This requires liquid forex markets for stablecoins.

USDC-USD and USDT-USD pairs are liquid. But USDC-EUR or USDC-GBP pairs are far less liquid, making conversion difficult.

For stablecoins to become dominant in cross-border payments, they would need much deeper forex pairs. This is more likely to happen if local stablecoins (euro stablecoins, pound stablecoins, etc.) become dominant in their regions.

Current State and Prospects

Currently, stablecoins are used for some cross-border payments, particularly among crypto-native users and traders. But they remain marginal compared to traditional banking and payment systems.

For stablecoins to achieve massive cross-border adoption, several conditions are needed:

• Deeper liquidity in regional stablecoin pairs
• Better regulatory clarity
• Integration with traditional banking systems
• Reduction of on-ramp and off-ramp friction (converting between stablecoins and local currency)

These are developing but remain incomplete.

Central Bank Tokenization and Wholesale Stablecoins

A parallel development is the creation of wholesale stablecoins designed for central bank and institutional use.

Project mBridge

A collaboration between the Bank for International Settlements (BIS), central banks (including those of Hong Kong, Thailand, UAE, and others), and financial institutions is developing mBridge—a multi-currency stablecoin platform designed for international settlements.

Rather than retail users holding stablecoins, central banks and large institutions would use mBridge for large-value, cross-border transfers.

This represents a different use case than retail stablecoins and could eventually subsume some cross-border payment functions currently performed by stablecoins.

The Role of Reserve Currency Status

Understanding why the dollar dominates stablecoins requires understanding reserve currency dynamics.

The US dollar is the world's dominant reserve currency held by central banks, governments, and institutions. This creates:

• Confidence that the dollar will remain stable
• Demand for dollar liquidity worldwide
• Dollar pricing in global markets (commodities, international trade)
• Incentives for platforms to offer dollar trading pairs

This status is not permanent; reserve currency dominance has changed historically. Sterling was the primary reserve currency in the 19th century before shifting to the dollar in the 20th.

However, for the foreseeable future, the dollar will likely remain dominant, supporting continued dominance of dollar-denominated stablecoins.

Market Dominance and Lock-in Effects

The dominance of USDT and USDC creates self-reinforcing dynamics:

More liquidity attracts more users: Traders prefer assets with higher liquidity because they can trade larger volumes without moving prices.

More users incentivize developers: DeFi developers build tools and infrastructure for the most liquid assets.

More infrastructure attracts more use: Better tools and integrations make dollar stablecoins more convenient to use.

More use generates more liquidity: Larger trading volumes mean even deeper liquidity.

This positive feedback loop is difficult for competitors to break. EUROC has excellent technical fundamentals and strong regulatory backing, but cannot match USDC's network effects.

Hypothetical Scenarios for Change

Several scenarios could shift stablecoin market dynamics:

Scenario 1: US Financial Crisis

A severe US financial crisis could undermine confidence in dollar-denominated assets. In such an environment, euro or other currency stablecoins might become preferable.

However, this would likely hurt crypto markets overall, making it unclear whether alternative stablecoins would benefit.

Scenario 2: Euro CBDC Success

If the ECB's digital euro becomes widely available and well-functioning, it could reduce demand for private euro stablecoins. However, it might also create new demand for stablecoins as different tools for different purposes.

Scenario 3: Regulatory Restriction of USDT/USDC

If US regulators severely restricted USDT and USDC, alternative stablecoins might benefit. However, such restrictions would likely apply to all stablecoins, not just dollar-denominated ones.

Scenario 4: Emerging Market Growth

If cryptocurrency adoption accelerates in emerging markets with unstable currencies, demand for emerging market stablecoins could grow substantially. However, dollar stablecoins would still serve as the backing asset.

Current Trends and Adoption Metrics

As of 2024-2025:

• USDT: Approximately 100$+ billion in market capitalization
• USDC: Approximately 30-40 billion in market capitalization
• EUROC: Approximately 1-2 billion in market capitalization
• All other regional stablecoins combined: Less than 5 billion

This disparity illustrates how completely dollar stablecoins dominate the market.

Key Takeaways

• Dollar-denominated stablecoins (USDT, USDC) dominate despite theoretical advantages for regional alternatives.
• Euro stablecoins (EUROC, EURT) exist but have far lower market penetration than dollar stablecoins.
• Network effects, liquidity, and established infrastructure strongly favor dollar stablecoins even among euro-area users.
• Emerging market stablecoins are more successful in their home regions but remain niche globally.
• Central bank digital currencies will eventually provide state-backed alternatives to private stablecoins.
• Multi-currency and basket stablecoins have been tested but have not achieved significant adoption.
• Regulatory frameworks like MiCA increasingly apply to non-USD stablecoins, creating more formal requirements for issuance.
• Cross-border payment use cases for stablecoins remain under-developed due to liquidity and conversion challenges.
• Reserve currency status of the dollar and strong network effects create powerful structural advantages for dollar stablecoins.
• The future likely involves coexistence of dominant dollar stablecoins, growing regional variants, and eventual CBDC competition.

Understanding the dynamics of multi-currency stablecoins reveals both the power of network effects and the possibility of diverse solutions for different user needs. As the stablecoin ecosystem matures, regulatory frameworks will formalize requirements while regional preferences and CBDCs will drive greater diversification beyond pure dollar dominance. The dominance of dollar stablecoins is not inevitable forever, but the structural factors supporting it are formidable.
