EUR Stablecoins and MiCAR: A Critical Assessment of the EU’s Regulatory Architecture

The global stablecoin market has grown exponentially in the last 5 years, yet EUR-denominated tokens have historically represented only negligible fraction of this expansion. Stablecoins by the US dollar (such as USDT and USDC) dominate with market capitalizations exceeding €200 billion, while EUR-backed stablecoins stayed below €400 million before MiCAR and increased only up to € 1 billion after. This imbalance reflected firstly the unquestionable dollar’s status and secondary the regulatory uncertainty that may discouraged institutional participation in European stablecoin issuance. MiCAR fundamentally altered this landscape. So, by establishing clear authorization pathways, prudential requirements, and consumer protections tailored to crypto-assets, the regulation provides the legal certainty that issuers and investors require. The result has been immediate and measurable: EUR stablecoin market capitalization has surpassed €1 billion as of December 2025, authorized issuers may now operate across multiple Member States, and stakeholders like traditional financial institutions or subsidiaries of European banks have also entered the market. This essay looks at the EMT framework through five sections. Section 2 traces how the concept evolved from traditional electronic money under Directive 2009/110/EC to the EMT regime, examining redemption rights, interest prohibitions, and white paper requirements. Section 3 analyzes MiCAR’s reserve requirements and prudential supervision, contrasting the European approach with the United States’ GENIUS Act to reveal divergent regulatory philosophies: MiCAR mandates integration with European credit institutions while GENIUS allows direct holdings in sovereign debt instruments. Section 3.1 examines how each framework treats stablecoin operations within issuing institutions. Long story short, MiCAR’s unified balance sheet approach versus GENIUS’s mandatory bankruptcy-remote subsidiaries; a structural difference with profound implications for crisis scenarios. Section 4 assesses market outcomes since MiCAR’s went into effect, evaluating whether the regulation has created a thriving EUR stablecoin ecosystem or merely a regulated enclave within a dollar-dominated global market. Section 5 answer the question MiCAR never asked: why do folks demand for alternatives to traditional banking exist in the first place? The regulatory paradox emerges: a framework designed to reduce systemic risk may concentrate it within the European banking system, the outcome that alternative financial infrastructure was designed to avoid.

1. Conceptual Foundations: From Electronic Money to E-Money Tokens

To fully understand how EMTs are treated by the regulations, someone needs firstly to look at the dynamics of existing concepts in EU financial law. The Payment Services Directive (hereinafter PSD2 and/or Directive 2015/2366/EE) defines “funds” to include banknotes, coins, scriptural money, and electronic money.¹ Electronic money (as established by the Electronic Money Directive 2) constitutes electronically stored monetary value issued upon receipt of funds for the purpose of making payment transactions and accepted by persons other than the issuer.² While the Electronic Money Directive 2 (hereinafter EMD2 and/or Directive 2009/110/EC) provides a foundation for regulating electronic money, it was drafted before the widespread adoption of distributed ledger technology (DLT) or blockchains and doesn’t explicitly address the nuances of tokenised forms of e-money. So, based of EU’s point of view, EMTs represent a technological evolution of the concept of electronic money: EMTs are crypto-assets that claim to maintain stable value by referencing one official currency, but are recorded and transferred using DLT. MiCAR’s Article 48(2) explicitly provides that e-money tokens shall be deemed to be electronic money, thereby incorporating EMTs within the existing regulatory architecture while simultaneously subjecting them to additional crypto-specific requirements. This nested classification carries significant practical consequences; EMT issuers must satisfy both EMD authorization requirements and MiCAR-specific obligations, creating a dual regulatory burden that shapes market structure and competitive dynamics.

The distinction between Payment Service Providers and Electronic Money Institutions warrants clarification, as both categories appear throughout discussions of stablecoin regulation yet serve different functions within the EU’s financial architecture. PSPs authorized under PSD2 may execute payment transactions, operate money remittance services, issue payment instruments, and; following the Directive’s open banking provisions; provide account information and payment initiation services through standardized APIs. EMIs, by contrast, hold authorization under EMD2 to issue electronic money itself; a broader mandate that encompasses the PSP service catalogue while adding the critical capacity to create, distribute, and redeem stored monetary value. The practical implication for stablecoin markets is straightforward: while a PSP might facilitate transactions involving e-money tokens, only an EMI or credit institution may actually issue them. MiCAR extends this framework by permitting authorized EMIs to provide crypto-asset custody services, creating a pathway for traditional e-money issuers to expand into digital asset infrastructure without obtaining separate CASP authorization. This regulatory layering explains why entities seeking to issue EUR stablecoins must navigate EMD2 requirements as a precondition to MiCAR compliance; the stablecoin authorization builds upon, rather than replaces, the underlying e-money license.

The critical distinction between traditional electronic money and EMTs lies in the technological infrastructure that makes possible their issuance and transfer. Services such as PayPal balances or prepaid cards constitute electronic money under EMD, yet they operate through centralized databases controlled by the issuer. EMTs, by contrast, utilize distributed ledger technology (a decentralized record-keeping system where transactions are validated and recorded across multiple nodes without reliance on a single central authority). This technological difference is important for regulation: while the holder of traditional e-money must necessarily maintain a contractual relationship with the issuer to access and transfer value, EMT holders however can transfer tokens directly to third parties who have no pre-existing relationship with the issuer whatsoever. MiCAR acknowledges this distinction by establishing that the holder’s claim against the issuer arises from the token itself rather than from a contractual account relationship, fundamentally altering the legal nature of the holder-issuer dynamic.

Central to the EMT framework is the holder’s right to redemption at par value. Article 49 of MiCAR guarantees that EMT holders may, at any time, request redemption of the monetary value of their tokens from the issuer, receiving in return funds denominated in the referenced currency equal to the nominal value of the tokens redeemed. This right is perpetual and unconditional—issuers cannot impose temporal limitations or substantive conditions that would effectively restrict redemption. Furthermore, redemption must generally be provided free of charge; fees may be levied only where explicitly disclosed in the crypto-asset white paper and only in limited circumstances, such as where fees are proportionate to actual costs incurred. This robust redemption guarantee serves a dual purpose: it protects holders against issuer default or market illiquidity, and it provides the economic foundation for the token’s stable value by ensuring an arbitrage mechanism that aligns market price with par value.

MiCAR imposes a number of restrictions on EMTs that depart from the traditional e-money regime. Most notably, Article 50 most importantly states that issuers and crypto-asset service providers from granting interest or any other benefit related to the length of time a holder holds EMTs. This prohibition (which mirrors but strengthens the corresponding EMD provision)³ aims to preserve EMTs’ function as payment instruments rather than investment vehicles or stores of value. The rationale is both prudential and monetary: permitting interest on stablecoins could speed up capital flows from bank deposits to tokenized alternatives, potentially destabilizing the banking sector and complicating monetary policy transmission. Additionally, EMT issuers must publish a crypto-asset white paper containing prescribed disclosures regarding the token’s characteristics, the issuer’s governance, reserve composition, redemption procedures, and associated risks. This white paper must be notified to the competent authority before publication and creates liability for the accuracy of its contents, establishing a disclosure regime analogous (but not the same as) to prospectus requirements for securities.

2. Reserve Requirements & Prudential Supervision

The prudential framework for e-money tokens under MiCAR is one of the most complicated and politically charged parts of the regulation. Unlike traditional electronic money, where reserve requirements focus primarily on safeguarding client funds, MiCAR has a layered architecture of reserve composition rules, concentration limits, and liquidity requirements designed to address concerns specific to crypto-asset markets. Namely, the risk of sudden mass redemptions and the potential for stablecoin failures to transmit instability to the broader financial system. The framework distinguishes between “ordinary” EMTs and “significant” EMTs subjecting the latter to enhanced supervision by the European Banking Authority rather than national competent authorities. Significant EMTs have reserves of more than €5 billion or more than 10 million users. This tiered approach reflects the EU’s assessment that large-scale stablecoins pose systemic risks just like to systemically important financial institutions.

Article 36 of MiCAR establishes the core reserve composition requirements. All EMT issuers must maintain reserves equal to 100% of the outstanding token value at all times—a full-reserve requirement that, in principle, ensures every token can be redeemed at par. On the other hand, MiCAR goes beyond full-reserve backing: it mandates that at least 30% of reserves be held as deposits in EU credit institutions. For significant EMTs, this threshold increases to 60%. The rationale (as stated in the regulation’s recitals) is to ensure that issuers can meet redemption requests at any time. The EBA’s regulatory standards also specify that 20% of reserves must be accessible within one day, and 30% within five business days. Concentration limits also apply under a tiered structure: no more than 25% of reserves may be held with one only single systemically important institution, 15% with large credit institutions, and 5% with smaller banks. Another cap restricts deposits to 1,5% of any single bank’s total assets. These rules effectively require issuers to maintain relationships with multiple banking partners. This is a practical challenge in a market where, as industry participants have noted, “crypto-friendly banks in Europe” are still hard to find.

Beyond reserve composition, MiCAR imposes liquidity management obligations and own funds requirements modelled on; though not identical to; those applicable to banks. Issuers must conduct liquidity stress testing, maintain recovery plans, and demonstrate capacity to meet redemption demands under stress. Non-significant EMT issuers must hold own funds equal to 2% of average outstanding tokens; for significant EMTs, this rises to 3%. Reserve assets are limited to cash, deposits in EU credit institutions, and financial instruments that qualify as “highly liquid” under EBA standards: principally government bonds with zero regulatory haircuts and reverse repurchase agreements backed by sovereign debt. Covered bonds may constitute up to 35% of reserves. Corporate bonds, precious metals, and other yield-generating assets fall outside these categories because they cannot be liquidated rapidly without material loss. This conservative approach constrains the business model available to issuers considerably. One question remains that the regulation itself does not address: whether channeling stablecoin reserves into the European banking system reduces systemic risk or merely relocates it.

The United States’ GENIUS Act, enacted in 2025, establishes a structurally different prudential architecture for “payment stablecoins”; the statutory term reflecting the American classification of stablecoins as payment infrastructure rather than electronic money variants. While both regimes mandate 100% reserve backing, the American framework imposes no minimum threshold for bank deposits—indeed, it deliberately steers reserves away from the banking system. Permitted reserve assets under GENIUS comprise United States coins and currency, demand deposits at insured depository institutions, Treasury bills, notes, or bonds with remaining maturities of 93 days or less, repurchase agreements backed by such Treasury securities with terms not exceeding seven days, and money market funds invested exclusively in the foregoing categories. Critically, the Act includes an explicit prohibition on rehypothecation: “Reserves described under paragraph (1)(A) may not be pledged, rehypothecated, or reused, except for the purpose of creating liquidity to meet reasonable expectations of requests to redeem payment stablecoins“. Furthermore, where MiCAR leaves reserves vulnerable as ordinary bank deposits subject to €100,000 deposit insurance limits, GENIUS mandates that issuers maintain reserves in segregated, bankruptcy-remote accounts held by qualified custodians. In the event of issuer insolvency, stablecoin holders benefit from a perfected, first-priority security interest in the reserve assets, senior to all other claims against the issuer. Capital requirements remain principles-based—to be determined by the Federal Reserve, OCC, and state regulators—rather than the fixed 3% threshold applicable to significant EMTs under MiCAR. The structural implication is unmistakable: where MiCAR forces issuers into dependency relationships with European credit institutions, GENIUS enables issuers to hold reserves directly in sovereign debt instruments with near-zero credit risk.

The terminological distinction between “payment stablecoins” and “e-money tokens” is not merely semantic; it reflects fundamentally divergent regulatory diagnoses of what stablecoins represent within the broader financial architecture. By classifying stablecoins as a species of electronic money, MiCAR put them under Directive 2009/110/EC: a regime originally designed, as the EMD2 preamble explicitly states, to regulate “an electronic surrogate for coins and banknotes, which is to be used for making payments, usually of limited amount and not as means of saving.” The Directive further specifies that “only electronic money institutions duly authorised… credit institutions authorised… may issue electronic money“, preserving the institutional monopoly of traditional finance over payment services. The GENIUS Act takes a different view. Rather than treating stablecoins as a variant of electronic money, it recognizes “payment stablecoins” as a sui generis category of payment infrastructure. The definition covers digital assets that are made for payment or settlement that maintain a fixed value against fiat currency. This classification matters: it means payment stablecoins receive regulatory treatment tailored to their function rather than inherited from pre-existing e-money rules.The Act applies exclusively to “payment stablecoins”; stablecoins structured as securities, commodities, deposits, or backed by assets other than fiat currency (such as asset-referenced tokens or endogenously collateralized stablecoins) remain outside the GENIUS framework and subject to existing regulatory regimes. This narrow scope ensures that stablecoin regulation does not inadvertently subsume other digital asset categories requiring different legal treatment. The European approach thus channels fiat-referenced stablecoins into a regulatory architecture built for PayPal balances and prepaid cards; the American approach acknowledges that the technology warrants institutional separation from traditional electronic money infrastructure.

This regulatory difference will likely produce segmented market dynamics: MiCAR-compliant issuers (Circle’s EURC, new EU bank issuers) dominating the EU euro stablecoin market, while non-MiCAR alternatives (Tether’s USDT) retaining dominance in global USD use cases and crypto trading. The pattern is already clear: Tether explicitly turned down the chance to obtain an EU EMI license, despite the legal pathway being available, citing concerns that MiCAR’s bank deposit requirements and transparency mandates would compromise its global reserve flexibility. Circle’s 2024 authorization by France’s ACPR (becoming the first major MiCAR-compliant USD stablecoin issuer) illustrates that compliance is technically feasible but commercially unpalatable to issuers prioritizing operational autonomy over European market access. The regulatory choice confronting issuers is thus not between “safe” and “risky” but between two distinct models of systemic risk management: integration with European credit institutions versus dispersion across sovereign debt instruments.

The variation between these frameworks has attracted significant scholarly and institutional attention. As the World Economic Forum observed: “the GENIUS Act is even more conservative than MiCA. It eschews bank-related risks by prohibiting issuers from holding longer maturity bonds in their reserves. It also doesn’t require either 30 or 60% of reserves to be held in banks, which could introduce credit risks from banking into stablecoin activities“. The paradox is striking: the American framework, often characterized as deregulatory, produces a more prudentially conservative outcome than Europe’s ostensibly stringent regime. Legal commentators reinforce this assessment, noting that “the GENIUS Act demands reserves be held in cash or short-term U.S. Treasuries, and forces banks to issue from a bankruptcy-remote subsidiary. This insulates the reserves from the bank’s own credit risk. MiCAR, conversely, mandates that a portion of EMT reserves (at least 30%) be held as deposits in EU credit institutions, which re-introduces bank credit risk into the system“. The Federal Reserve’s own analysis acknowledges that when stablecoin issuers hold reserves primarily as bank deposits, this “possibly increas[es] deposit concentration and a shift from insured retail deposits to uninsured wholesale deposits,” with banks facing “more concentrated, uninsured, wholesale deposits, increasing both liquidity risk and funding costs“. The arithmetic is sobering: banks operating under fractional reserve requirements retain approximately 10-15% of deposits as liquid reserves. A significant EMT with €10 billion held as bank deposits thus depends on the banking system’s capacity to mobilize €1-1,5 billion in liquid reserves against potential redemption demands of €2 billion or more; a threshold that the 2023 Silicon Valley Bank crisis, where $42 billion exited within hours and an additional $100 billion was staged for withdrawal the following day, demonstrated is not assured. Under GENIUS, banks issuing stablecoins must do so “from a separate entity and balance sheet that’s set apart from its core banking business“, ensuring insulation from “the leverage, maturity transformation and lending activities of the bank’s core operations. This same requirement does not exist under MiCA“. The implication is profound: a regulatory framework explicitly designed to reduce systemic risk may have increased it by re-entrenching the banking system’s fundamental mechanics—the very mechanisms that stablecoin technology was designed to bypass. This paradox reflects MiCAR’s conflation of two distinct regulatory objectives: prudential safety (ensuring stablecoin reserve stability) and monetary policy (anchoring stablecoins to EU financial infrastructure). GENIUS isolates prudential concerns. MiCAR entangles them.

2.1. Accounting Architecture: On-Balance Sheet versus Off-Balance Sheet

The structural treatment of stablecoin operations within issuing institutions reveals a critical divergence between the two frameworks that practitioners rarely examine. Section 16 of the GENIUS Act explicitly permits banking institutions providing custody services for payment stablecoins to exclude these digital assets from their balance sheets and to avoid holding regulatory capital against them, except where necessary to mitigate operational risks. Simultaneously, the Act mandates that banks issuing stablecoins must do so “from a separate entity and balance sheet that’s set apart from its core banking business“—ensuring reserves remain insulated from the leverage, maturity transformation, and lending activities of the bank’s core operations. MiCAR imposes no comparable structural separation requirement: an EMT issuer may operate stablecoin issuance as an integrated business line, with reserves appearing on the same balance sheet alongside other assets and liabilities.

The practical implications become stark when one examines crisis scenarios. Consider a European bank operating under MiCAR with total assets of €10 billion, including €500 million in stablecoin reserves held on its unified balance sheet. If the bank incurs €200 million in loan losses, management retains the operational flexibility to liquidate portions of the stablecoin reserves to shore up capital ratios—protecting the institution but potentially leaving stablecoin holders with €300 million backing €500 million in outstanding tokens until new reserves are sourced. Under GENIUS, the same bank would operate its stablecoin programme through a bankruptcy-remote subsidiary: the €500 million in reserves exists in a legally separate entity with its own balance sheet, inaccessible to satisfy claims arising from the parent bank’s core operations. The parent’s loan losses cannot touch the subsidiary’s reserves. This structural separation means that stablecoin holders enjoy protection equivalent to secured creditors with first-priority claims, regardless of the parent institution’s financial distress.

The flexibility implications cut both ways, though not symmetrically. MiCAR’s unified balance sheet approach permits issuers to deploy capital more efficiently across business lines and to respond dynamically to liquidity pressures—advantages that incumbent banks with diversified operations may value. However, this same flexibility creates the transmission channel through which traditional banking risks flow into stablecoin operations, undermining the very «narrow banking» model that full reserve backing was intended to approximate. GENIUS sacrifices operational flexibility for structural safety: the ring-fenced subsidiary cannot draw on parent resources during market stress, but neither can parent distress contaminate stablecoin reserves. For non-bank fintech issuers—entities without legacy banking operations to leverage—GENIUS’s architecture imposes no meaningful constraint while providing maximum holder protection. MiCAR, by contrast, effectively channels stablecoin issuance toward incumbents capable of absorbing the integrated balance sheet’s capital and liquidity demands, creating barriers to entry that regulatory rhetoric about “innovation” rarely acknowledges.

3. Stablecoins Market: MiCAR Issuers and Global Distribution

The implementation of MiCAR’s stablecoin provisions on 30 June 2024 created a regulated EUR stablecoin market for the first time—yet the scale of that market requires honest assessment. By late 2024, total EUR stablecoin capitalization had reached approximately €680 million, having doubled from roughly €300 million when the framework took effect. By December 2025, the market had surpassed €1 billion—a trajectory that industry observers have cited as validation of MiCAR’s approach. The figure, however, represents approximately 0.2% of the global stablecoin market, which exceeds $310 billion and remains overwhelmingly dominated by USD-denominated tokens. The European Central Bank’s own assessment acknowledges that «euro-denominated stablecoins remain marginal». Whether MiCAR has created a thriving EUR stablecoin ecosystem or merely a regulated enclave within a dollar-dominated global market is a question that the following analysis of licensed issuers and market dynamics cannot avoid.

As of December 2024, approximately eight to ten entities have obtained authorization to issue EUR-denominated e-money tokens under MiCAR, either as electronic money institutions or credit institutions. The principal issuers include Circle Internet Financial Europe SAS (issuing EURC), Société Générale-FORGE (EURCV), Quantoz Payments B.V. (EURQ), Banking Circle S.A. (EURI), StablR (EURR), Monerium EMI ehf. (EURe), and Schuman Financial (EURØP). Additional issuers operate from Finland (Membrane Finance, acquired by Paxos in 2025) and Germany (AllUnity GmbH, launching EURAU in July 2025). The market structure reveals significant concentration, though not in the manner one might expect: Stasis EURS—a token predating MiCAR that has since achieved compliance—commands approximately 40% of total EUR stablecoin capitalization, while Circle’s EURC holds approximately 30%. The remaining issuers collectively share minority positions. This concentration reflects both first-mover advantages and the substantial barriers to entry that the regulatory framework imposes on smaller market participants.

The geographic distribution of licensed EUR stablecoin issuers reveals a concentrated pattern that may concern observers hoping MiCAR would foster pan-European competition. France’s Autorité de Contrôle Prudentiel et de Résolution (ACPR) has authorized three issuers—Circle, SG-FORGE, and Schuman Financial—establishing Paris as the de facto hub for EUR stablecoin licensing. The Netherlands hosts Quantoz Payments under De Nederlandsche Bank supervision and will house the forthcoming nine-bank consortium. Luxembourg’s Commission de Surveillance du Secteur Financier (CSSF) licensed Banking Circle, while Malta’s Financial Services Authority authorized StablR. The remaining twenty-two EU member states have attracted no EUR stablecoin issuers. This geographic concentration raises questions about whether MiCAR has created a genuinely European market or merely enabled a handful of jurisdictions with pre-existing fintech infrastructure to dominate. For practitioners in jurisdictions without established issuers—including Cyprus, where the Central Bank of Cyprus holds regulatory authority over EMT issuance but has attracted no applicants—the practical implication is clear: clients seeking to issue EUR stablecoins will likely be advised to establish in France or the Netherlands, regardless of where their operations or customers are located. The obstacle is not jurisdictional capability but regulatory posture: the Central Bank of Cyprus has not signaled the same level of engagement with prospective stablecoin issuers that France’s ACPR or the Netherlands’ DNB have demonstrated through published guidance, expedited procedures, and precedent-setting authorizations.

The fact that traditional banks are now issuing EUR stablecoins should be carefully glanced at, not celebrated. In April 2023, Société Générale-FORGE launched EURCV. In July 2024, they changed it to a MiCAR-compliant token. In August 2024, Banking Circle launched EURI. In September 2025, nine European banks—including ING, UniCredit, and CaixaBank—announced a consortium to launch a EUR stablecoin by end of 2026, explicitly framing the initiative as a response to American dominance in stablecoin markets. These developments shows institutional recognition that EUR stablecoins represent strategic infrastructure rather than speculative instruments. Yet the consortium’s rationale reveals an uncomfortable truth: by September 2025; fifteen months after MiCAR stablecoin provisions took effect; European banks felt compelled to announce plans for “a real European alternative” precisely because existing MiCAR-compliant offerings had failed to achieve meaningful market penetration. The consortium is less a validation of MiCAR’s success than an acknowledgment that the regulation alone proved insufficient to catalyze a competitive EUR stablecoin ecosystem.

Tether’s response to MiCAR illustrates the limits of territorial regulation in global digital asset markets. Rather than restructure its operations to comply with MiCAR’s reserve requirements—which mandate 30-60% bank deposits and which CEO Paolo Ardoino characterized as creating “systemic risk” by exposing stablecoin reserves to bank credit risk—Tether discontinued its EUR-denominated EURT token in November 2024. Tether simultaneously invested in two MiCAR-compliant issuers, Quantoz Payments in the Netherlands and StablR in Malta. Through its Hadron platform, launched in November 2024, Tether provides tokenization infrastructure enabling third parties to issue compliant tokens while Tether captures technology licensing revenue without direct regulatory exposure. This strategy—exit direct compliance, invest in compliant proxies, provide enabling infrastructure—demonstrates sophisticated regulatory arbitrage that MiCAR’s framers may not have anticipated. European regulators cannot compel Tether to comply with MiCAR, yet Tether-backed issuers operate freely within the European market.

Comparative analysis of stablecoin frameworks outside Europe challenges assumptions that MiCAR’s stringency produces superior outcomes. Singapore’s Monetary Authority finalized its stablecoin framework in August 2023, requiring full reserve backing without mandatory bank deposits; StraitsX’s SGD-denominated stablecoin achieved institutional adoption and Coinbase listing by October 2025. The UAE’s Central Bank implemented payment token regulation in August 2024 with similar flexibility, attracting $30 billion in digital assets within twelve months. Japan’s Financial Services Agency licensed JPYC in August 2025 under a framework permitting up to 50% government bond backing. None of these jurisdictions impose MiCAR’s bank deposit requirements, and all have produced functioning stablecoin ecosystems in their respective currencies. The contrast raises an uncomfortable question: has MiCAR’s emphasis on prudential safety through bank integration created precisely the concentration risk it sought to prevent, while jurisdictions with lighter-touch frameworks achieved comparable regulatory objectives without impeding market development?

For the practitioner advising clients on EUR stablecoin strategy, the preceding market survey yields conclusions that regulatory optimism cannot obscure. EUR stablecoins remain marginal at 0.2% of global stablecoin capitalization. Geographic concentration in four member states undermines MiCAR’s single-market aspirations. The world’s largest stablecoin issuer chose exit over compliance while maintaining indirect European exposure. Traditional banks entered the market not because MiCAR succeeded but because it failed to produce competitive alternatives to USD-denominated tokens. And jurisdictions without established regulatory precedent—including Cyprus—face a practical choice between waiting for domestic regulators to develop stablecoin expertise or directing clients to France and the Netherlands where authorization pathways are proven. MiCAR created a regulatory framework; whether it created a thriving EUR stablecoin market remains, at best, an open question.

4. The Regulatory Paradox: Financial Inclusion and the Question MiCAR Never Asked

The fundamental question that MiCAR never poses is not “how do we regulate stablecoins?” but “why does demand for alternatives to banking exist in the first place?” Approximately 1.4 billion adults worldwide remain unbanked—excluded by documentation requirements, minimum balance thresholds, geographic limitations, or simple cost. Blockchain technology, whatever its speculative excesses, addressed a genuine structural deficit in global financial infrastructure. As the European Investment Bank acknowledged in its 2019 Working Paper, “FinTechs, the financial technology and innovation that competes with traditional financial methods in the delivery of financial services, has the potential to improve the reach of financial services to the broader public and facilitate the creation of a credit record, especially in the developing world.” The World Bank similarly recognized that distributed ledger technology “enables copies of the ledger to be shared across multiple locations and in a decentralized manner without requiring a trusted central authority”—a feature particularly valuable in regions where trust in centralized institutions is low or where such institutions simply do not exist.

The emergence of alternative value transfer systems is not a phenomenon unique to the digital age. Long before Bitcoin’s 2008 white paper, the Hawala network facilitated cross-border remittances across the Islamic world—operating on trust, minimal documentation, and settlement mechanisms entirely divorced from formal banking infrastructure. The persistence of such systems across centuries reflects a structural reality: alternative financial infrastructure does not emerge because users seek to evade regulation, but because traditional banking remains inaccessible to significant portions of the population. When Indonesia achieved an increase in financial inclusion from 49% to 83% between 2014 and 2023, this transformation occurred not through traditional banking expansion but through mobile money platforms operating under regulatory frameworks considerably lighter than MiCAR. Kenya’s M-Pesa demonstrated the same pattern a decade earlier. Launched in 2007, the mobile money platform reached 17 million active users by 2012 without requiring its users to hold bank accounts or visit bank branches. The service operated on basic feature phones via SMS; no smartphones, no internet connection, no physical banking infrastructure. By the time European regulators began drafting MiCAR, M-Pesa had already processed more transactions annually than Western Union handles globally. This history does not appear to have informed the regulation’s design.

A comparison with the United States’ GENIUS Act reveals two fundamentally different regulatory diagnoses of what stablecoins represent. The American approach treats stablecoins as a new category of payment infrastructure—permitting non-bank issuers to participate, requiring reserve backing in Treasury securities rather than bank deposits, and thereby dispersing systemic risk across the US government debt market rather than concentrating it within the banking sector. MiCAR, by contrast, subsumes stablecoins under the Electronic Money Directive framework—a regime originally designed not to create alternatives to banking, but to digitize existing banking infrastructure. As the EMD2 preamble explicitly states, electronic money was conceived as “an electronic surrogate for coins and banknotes, which is to be used for making payments, usually of limited amount and not as means of saving.” The Directive further specifies that “only electronic money institutions duly authorised… credit institutions authorised… may issue electronic money“—preserving the institutional monopoly of traditional finance over payment services. MiCAR thus channels stablecoins into a regulatory architecture built for PayPal and prepaid cards, not for systems that emerged precisely because traditional banking infrastructure was inaccessible. Both frameworks demand full reserve backing; the critical divergence lies in implementation. As the World Economic Forum observed, “the GENIUS Act eschews bank-related risks by prohibiting issuers from holding longer maturity bonds in their reserves. It also doesn’t require either 30 or 60% of reserves to be held in banks, which could introduce credit risks from banking into stablecoin activities.” GENIUS disperses reserves across sovereign debt instruments with near-zero credit risk. MiCAR concentrates reserves in commercial banks that, by design, lend out the majority of their deposits.

The structural implications of this divergence became apparent during the 2023 US regional banking crisis. When Silicon Valley Bank collapsed, the FDIC reported that “$42 billion in deposits had left the bank” within hours, with “an additional $100 billion staged to be withdrawn the next day“—and “over 90 percent of SVB’s deposits were uninsured.” The arithmetic under MiCAR is sobering: if a stablecoin issuer holds €10 billion in reserves and regulation requires 60% in bank deposits (€6 billion), and those banks operate under standard fractional reserve ratios retaining approximately 10% as liquid reserves (€600 million), then a redemption demand of €2 billion triggers a liquidity crisis for both the bank and the stablecoin simultaneously. EU deposit insurance covers €100,000 per depositor—a figure negligible relative to stablecoin market capitalizations measured in billions. The very mechanism designed to ensure stability—integration with the regulated banking system—becomes the transmission channel for instability. MiCAR thus presents a regulatory paradox: a framework explicitly designed to reduce systemic risk in crypto-assets may have inadvertently concentrated that risk within the European banking system—the precise outcome that alternatives to banking were developed to avoid.

The delisting of non-compliant stablecoins from European exchanges in early 2025 provided an empirical test of MiCAR’s regulatory strategy—and the results were not encouraging. When ESMA issued its guidance in January 2025 requiring the removal of unauthorized stablecoins, major exchanges including Coinbase, Kraken, and Binance delisted USDT by March 31, 2025. The intended outcome was migration to MiCAR-compliant alternatives such as Circle’s EURC. The actual outcome was different: EUR stablecoin liquidity declined by approximately 18% in the first quarter of 2025, while compliant alternatives captured less than 2% of the market previously served by USDT. Users did not migrate to regulated alternatives—they migrated to unregulated channels. As the Financial Crime Academy has observed regarding alternative remittance systems generally, “these systems provide a means for individuals to transfer funds across borders quickly, conveniently, and at a lower cost compared to traditional banking channels”—and when regulated channels become inaccessible, informal channels absorb the demand. The delisting thus demonstrated a pattern familiar from the history of Hawala: prohibition does not eliminate demand for alternative infrastructure; it merely relocates that demand to less transparent venues.

If MiCAR succeeds in fully assimilating crypto-assets into the traditional banking framework, the result will not be “consumer protection” but rather an artificial distinction between two categories of credit institutions—those that maintain centralized ledgers and those that maintain distributed ledgers. The underlying demand that gave rise to alternative systems in the first place will remain unaddressed. As the IMF has noted regarding informal remittance systems, “highly trust-based, informal remittance systems have a long history of being reliable, inexpensive, speedy, accessible, and a convenient way of transferring funds… using minimal or no documentary requirements.” MiCAR’s architects never asked why such systems persist despite decades of regulatory pressure. The answer is not regulatory arbitrage or criminal intent—it is structural exclusion from formal financial services. The father who gives his son twenty euros to buy groceries does not require a Mastercard terminal; the migrant worker sending remittances to a village without bank branches does not benefit from EMI authorization requirements. By treating stablecoins as a variant of electronic money rather than as infrastructure addressing a genuine gap in financial services, MiCAR may have foreclosed the possibility of regulated alternatives emerging within the European framework—leaving the unbanked with no option but to seek solutions elsewhere.

5.Concluding Remarks: The Direction of Walls

MiCAR’s architects constructed a regulatory fortress around EUR stablecoins, yet the critical question remains: in which direction do its walls face? In the 2001 film The Last Castle, a decorated general observes that the military prison where he is confined differs from medieval fortresses in one respect only: traditional castles were built to keep enemies out, whereas this one was built to keep people in. The observation carries unexpected resonance for financial regulation. The MiCAR framework mandates integration with European credit institutions, imposes concentration limits that effectively require issuers to cultivate relationships with multiple banking partners, and channels reserves through balance sheets that remain exposed to the very maturity transformation and leverage risks that precipitated the 2023 banking turmoil in the United States. What emerges is not a framework designed primarily to shield European consumers from the volatility of crypto-asset markets, but rather one designed to ensure that Europeans seeking alternatives to traditional banking find no alternatives at all, at least none operating within the regulated perimeter. The burden falls heavily on the banking sector, which must absorb stablecoin reserves while managing the liquidity and concentration risks those reserves introduce, all while maintaining the fractional reserve mechanics that stablecoin technology was architected to circumvent.

The contrast with other jurisdictions is instructive. Singapore, the UAE, Japan, and the United States under GENIUS have each produced functioning stablecoin ecosystems without requiring that reserves flow through commercial banks, and without the geographic concentration that has reduced MiCAR’s “single market” to four member states with licensed issuers. The American framework goes further, mandating bankruptcy-remote subsidiaries and prohibiting rehypothecation: structural separations that MiCAR declined to impose. Whether this divergence reflects differing assessments of systemic risk or differing assessments of what stablecoins represent (payment infrastructure versus electronic money variant) the market has rendered its verdict. EUR stablecoins remain at 0.2% of global capitalisation, Tether chose exit over compliance, and nine European banks felt compelled to announce a consortium precisely because existing MiCAR-compliant offerings had failed to achieve scale.

One might ask what the European Union genuinely seeks to contain. The regulation’s recitals speak of consumer protection and financial stability, yet the architecture suggests additional concerns that official documents do not articulate: populations bypassing banks they consider too expensive or too inaccessible, undocumented migrants transferring value outside institutional surveillance, and, in an era when economic sanctions constitute instruments of geopolitical strategy, the prospect of European citizens circumventing restrictions that the Union enforces with particular rigour. These are not illegitimate regulatory concerns, but they are not the concerns of prudential safety. MiCAR may ultimately succeed in assimilating crypto-assets into the European banking system. Whether it will address the structural exclusions that gave rise to alternative financial infrastructure in the first place is a question the regulation never asked and, by design, cannot answer.
