MiCA 2.0: The EU's Crypto Regulation Review and What It Means for Stablecoins and CASP Licensing

Introduction

Three years after the EU's Markets in Crypto-Assets Regulation (MiCA) became law, the regulatory landscape for crypto assets is undergoing a comprehensive review—commonly referred to as MiCA 2.0. With a public consultation expected to close around September 2026, the review aims to address the rapid evolution of stablecoins, tokenization, and decentralized finance. For crypto firms operating in the EU, understanding the potential changes to stablecoin regulation, CASP authorization requirements, and supervisory architecture is critical for strategic planning. This article examines the key issues in the MiCA 2.0 review, compares them with U.S. stablecoin regulatory developments, and explores compliance implications for crypto businesses.

The MiCA Review: Context and Timeline

MiCA (Regulation (EU) 2023/1114) came into force in 2023, with stablecoin provisions applying from 30 June 2024 and full application for Crypto-Asset Service Providers (CASPs) from 30 December 2024. The regulation established a harmonized framework for crypto assets across EU member states, covering issuers of asset-referenced tokens (ARTs) and e-money tokens (EMTs), as well as service providers.

As mandated by the regulation, the European Commission is conducting a review to assess its effectiveness and identify areas for improvement. The MiCA 2.0 consultation, expected to close around September 2026, will inform potential legislative amendments. Key areas of focus include stablecoin regulation, tokenization in wholesale finance, and the supervisory framework.

Stablecoin Regulation: Reserves, Yield, and Multi-Issuance

Stablecoins have grown significantly in institutional and wholesale finance, prompting intense debate in the MiCA 2.0 review. Several critical issues are on the table:

Reserve Requirements

Under MiCA, issuers of ARTs and EMTs must hold reserves in the banking system, a requirement that has drawn criticism for limiting yield and increasing counterparty risk. The European Central Bank (ECB) remains cautious about dollar-pegged stablecoins but has moderated its stance, tolerating them for remittances but not for wholesale settlement. In contrast, the U.S. GENIUS Act (proposed) allows stablecoin reserves to be held in government debt. The EU is now considering allowing stablecoin operators to buy European money market instruments, a move that would align more closely with the U.S. approach and potentially reduce reliance on bank deposits.

Yield Distribution and Deposit Flight Risks

The review is examining whether stablecoin issuers should be permitted to distribute yield to holders. Proponents argue that yield distribution could foster adoption, while regulators fear it could blur the line between stablecoins and deposits, triggering deposit flight from traditional banks. The ECB has expressed concern that yield-bearing stablecoins could undermine monetary policy transmission and financial stability.

Multi-Issuance Stablecoins

Multi-issuance stablecoins like USDC face fragmentation risks due to differing stakeholder views within the EU. The review is considering whether to allow multiple issuers for the same stablecoin and under what conditions. Harmonizing rules across member states will be crucial to avoid fragmentation and ensure a level playing field.

CASP Authorization and the Path to Centralized Supervision

Under MiCA, CASPs must obtain a license from a competent authority in their home member state, which then allows them to passport services across the EU. The review is evaluating whether this decentralized model is effective or whether supervision should be centralized.

The European Securities and Markets Authority (ESMA) is increasingly seen as the likely centralized supervisory body for crypto regulation in the EU. Centralization could streamline authorization, reduce regulatory arbitrage, and enhance enforcement consistency. However, it would also require significant resources and coordination with national competent authorities.

Case Study: Tothemoon's CySEC CASP License

A notable example of the current licensing regime is Tothemoon, a global crypto platform that obtained authorization from the Cyprus Securities and Exchange Commission (CySEC) as a CASP under MiCA. This authorization allows Tothemoon to offer its services across the EU under passporting rights, demonstrating the practical application of MiCA's harmonized framework. The case highlights the growing trend of crypto platforms seeking regulatory compliance to operate legally within the EU and underscores MiCA's role as a standard-setting regulation.

Comparison with U.S. Stablecoin Regulation

The U.S. regulatory landscape for stablecoins is still evolving. The proposed GENIUS Act would require stablecoin issuers to maintain reserves in government debt, similar to the EU's consideration of money market instruments. However, the U.S. lacks a comprehensive federal crypto framework akin to MiCA. Instead, state-level regimes (e.g., New York's BitLicense) and federal enforcement actions (by SEC, CFTC, FinCEN) create a fragmented environment. FinCEN has proposed rules requiring stablecoin issuers to comply with AML/CFT obligations, including reporting and recordkeeping. The MiCA 2.0 review may influence U.S. regulators as they develop a more cohesive approach.

Compliance Implications for Crypto Firms

Crypto firms operating in the EU should prepare for several potential changes stemming from the MiCA 2.0 review:

• Stablecoin Reserve Requirements: Firms may need to adjust their reserve strategies if the EU permits investment in money market instruments. Compliance teams should monitor the consultation outcomes and model the impact on yield and risk.
• Yield Distribution: If yield distribution is allowed, firms must ensure robust risk disclosures and compliance with financial stability requirements. Expect enhanced scrutiny from regulators on the classification of stablecoins as deposits or securities.
• Multi-Issuance Coordination: Firms involved in multi-issuance stablecoins should engage with EU policymakers to ensure their models align with emerging rules. Fragmentation risks may require legal restructuring.
• Centralized Supervision: If ESMA becomes the central supervisor, CASPs may face a single point of oversight, potentially simplifying compliance but also increasing scrutiny. Firms should invest in scalable compliance infrastructure.
• Passporting and Licensing: The current passporting regime under MiCA will likely continue, but firms should ensure their home member state authorization is robust. The Tothemoon case illustrates the value of obtaining a license in a well-regulated jurisdiction like Cyprus.

Key Takeaways

• The MiCA 2.0 review, with a consultation closing around September 2026, will shape the future of crypto regulation in the EU.
• Stablecoin regulation is the central focus, with debates on reserve requirements, yield distribution, and multi-issuance fragmentation.
• The EU is considering allowing stablecoin reserves in European money market instruments, aligning more closely with the U.S. GENIUS Act approach.
• ESMA is likely to become the centralized supervisory body, replacing the current decentralized model.
• Firms should monitor the review closely and prepare for changes to reserve rules, yield distribution, and supervisory architecture.
