EU prepares ‘MiCA 2.0’ revamp as US GENIUS Act rewrites stablecoin playbook
The European Union is gearing up for a significant overhaul of its flagship crypto law, Markets in Crypto‑Assets (MiCA), after the United States passed the GENIUS Act, a landmark stablecoin bill. Brussels is now weighing how to adapt its own rules for stablecoins, tokenized assets and crypto custody as global regulatory standards begin to diverge and harden.
According to officials cited in recent briefings, the European Commission plans to reopen key parts of MiCA from 2027, with a particular focus on how stablecoins issued from outside the bloc – especially from the US – should be handled. The move signals that MiCA, long touted as the world’s most comprehensive crypto rulebook, is already seen as a first draft rather than a final blueprint.
Stablecoins in the crosshairs after the GENIUS Act
The immediate catalyst for the rethink is the U.S. Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act. The law creates a federal framework for dollar‑pegged stablecoins and gives U.S. regulators clear oversight of issuers.
European policymakers now face an urgent question: how should EU law treat dollar stablecoins minted under this new U.S. regime when those tokens are offered to European users? Current MiCA provisions were crafted before the GENIUS Act existed, leaving a gray zone around foreign issuers that are regulated at home but still reach EU residents.
The forthcoming review is expected to examine:
– Whether non‑EU stablecoin issuers should be required to obtain an EU license or rely on recognition of their home‑country oversight.
– What limits, if any, should apply to the circulation and use of foreign‑issued stablecoins within the bloc.
– How to prevent regulatory arbitrage if U.S. rules are more permissive in certain areas than MiCA.
For U.S. stablecoin companies, the EU’s goal is to spell out a predictable path to operating across all 27 member states, reducing the patchwork of interpretations that has existed to date.
Beyond crypto: tokenized payments and deposits
The next phase of MiCA is not just about classic crypto tokens. Officials are also exploring expanding the regulation’s reach to cover tokenized versions of traditional money and bank liabilities – such as tokenized deposits and token‑based payment instruments.
At present, MiCA mostly deals with crypto‑native instruments like asset‑referenced tokens and e‑money tokens. But the rapid rise of tokenization projects inside banks and payment firms is blurring the boundaries between regulated financial products and blockchain‑based instruments.
Policymakers are considering:
– Whether tokenized bank deposits should fall under MiCA or remain entirely within existing banking law.
– How to treat tokenized payment rails that enable near‑instant transfers but use blockchain infrastructure.
– How to ensure consumer protections are equivalent, whether funds are held in a traditional account or represented by a token on a ledger.
This expansion would effectively pull parts of the traditional financial sector deeper into the crypto regulatory perimeter, reflecting a shift from “regulating crypto” to “regulating finance on new rails.”
MiCA licensing goes live as review starts
The discussions come just as MiCA’s main licensing regime has become fully operational. Since July 1, any crypto business serving EU customers must hold authorization as a Crypto‑Asset Service Provider (CASP) from a regulator in at least one member state before it can passport services across the entire bloc.
This regime covers a wide range of activities, including:
– Operating trading platforms and exchanges
– Providing custody and safekeeping of digital assets
– Executing orders, placing crypto, and offering advice on digital assets
– Providing crypto‑fiat exchange services
Despite these rules only just taking effect, the European Commission has already launched a formal consultation on potential upgrades to the framework, informally branded “MiCA 2.0” by industry participants. The consultation requests feedback on areas originally left out or only lightly addressed, including:
– Decentralized finance (DeFi) protocols and governance tokens
– Stablecoin design, reserve quality, and redemption practices
– New forms of tokenization in capital markets and payments
The consultation window is open through the end of August, after which the Commission will begin drafting concrete changes.
ESMA tightens the screws on custody and resilience
In parallel, EU regulators are sharpening their supervisory tools for firms already operating under MiCA. The European Securities and Markets Authority (ESMA) announced a multi‑year review focusing on the operational resilience of licensed CASPs, with a particular emphasis on custody functions.
From July through the first half of 2027, ESMA will examine how crypto firms:
– Segregate and safeguard client assets
– Manage private keys and wallet security
– Handle outages, cyberattacks and other operational disruptions
– Comply with disclosure and reporting obligations under MiCA
The review reflects lessons from high‑profile collapses and hacks in the crypto sector, where failures in custody and risk controls often translated directly into customer losses. EU oversight now aims to bring custody standards closer to those expected of traditional securities custodians and payment institutions.
US legislative momentum reshapes the global debate
While Europe adjusts MiCA, Washington is pushing forward with a broader reshaping of digital asset rules. Beyond the GENIUS Act, U.S. lawmakers are advancing the Digital Asset Market Clarity Act, a bill designed to define the market structure for digital assets and clarify the roles of different regulators.
The Market Clarity bill, which has already passed two House committees, aims to:
– Distinguish between digital commodities and digital securities
– Clarify which assets fall under securities law and which under commodities oversight
– Set conditions for secondary trading of tokens without triggering additional registration requirements
A Senate vote is expected as early as July, underscoring how quickly the U.S. is moving from piecemeal guidance to a more coherent framework. For European officials, this accelerates pressure to ensure MiCA remains compatible with – or at least interoperable with – emerging U.S. rules.
Converging goals, diverging tools
Taken together, the EU’s MiCA process and the U.S. legislative push show that regulators on both sides of the Atlantic are converging on the same core objective: integrating stablecoins, tokenized assets and digital asset services into the mainstream financial system without repeating the excesses of the last crypto boom.
However, the paths differ.
– The EU favors a single, bloc‑wide code with detailed licensing and conduct rules, applied through national regulators but shaped centrally.
– The U.S. is opting for multiple laws, layered on top of an already complex financial regulatory structure, with federal and state powers overlapping.
For global firms, this divergence means compliance strategies must be customized. A stablecoin issuer or exchange can no longer design a single regulatory playbook and expect it to work everywhere; it must be able to map its operations onto at least two heavyweight frameworks and, increasingly, to regional variations in Asia and the Middle East.
What this means for stablecoin issuers
Stablecoin providers, particularly those with U.S. roots, are at the center of these changes. Under MiCA’s existing rules, issuers of asset‑referenced tokens and e‑money tokens face caps on daily transaction volumes, strict reserve requirements, and obligations to offer prompt redemption at par.
The GENIUS Act introduces parallel expectations in the U.S., including requirements around:
– Reserve composition and reporting
– Redemption guarantees
– Supervision by approved regulators
As the EU reviews MiCA and the U.S. fleshes out its oversight, issuers will likely have to:
– Harmonize reserve management practices to meet the strictest common standard.
– Build legal entities and governance structures that can satisfy both regimes.
– Prepare for tighter scrutiny of cross‑border flows, especially where stablecoins are used for payments or remittances rather than trading alone.
In practice, this may raise the cost of launching and maintaining a stablecoin, but it could also entrench a smaller number of large, compliant issuers while pushing weaker operators out of core markets.
Implications for exchanges, custodians and DeFi
Crypto exchanges and custodians in Europe already feel the first wave of MiCA impact, from licensing burdens to reporting requirements. The next phase of reform will likely widen that pressure, particularly as regulators dig deeper into custody and operational resilience.
Key implications include:
– Higher capital, insurance or reserve expectations for custodians that hold customer funds and keys.
– More rigorous incident reporting rules when platforms face hacks or technical failures.
– Potential scrutiny of how centralized exchanges list and support stablecoins created outside the EU.
DeFi protocols, while not yet fully captured by MiCA, are firmly on the radar for MiCA 2.0. Authorities are exploring how far existing concepts like “issuer,” “operator” or “service provider” can be stretched to cover decentralized systems where control is fragmented. That debate could shape whether and how large DeFi projects can engage with regulated stablecoins and tokenized assets without being forced into centralized structures.
The broader shift toward tokenized finance
Beyond the immediate headlines about laws and bills, the emerging regulatory alignment is a response to a deeper structural shift: the migration of financial services onto tokenized, programmable infrastructure.
Banks, asset managers and payment institutions are experimenting with:
– Tokenized money market funds and bonds
– On‑chain collateral management and settlement
– Institutional‑grade stablecoins and deposit tokens for wholesale payments
If MiCA expands to cover tokenized deposits and payments, and if U.S. rules continue to define on‑chain instruments in terms of existing financial categories, the border between “crypto” and “traditional finance” will steadily fade. Supervision will increasingly focus on functions – custody, settlement, issuance, risk management – rather than on whether an asset is “crypto” or not.
What to watch next
Over the next 12-24 months, market participants should monitor several inflection points:
– The outcome of the EU’s MiCA 2.0 consultation and which topics are prioritized for legislative change.
– The detailed implementation of the GENIUS Act through guidance and rulemaking in the U.S.
– The final form and scope of the Digital Asset Market Clarity Act in Congress.
– ESMA’s interim findings on custody and operational resilience, which may quickly translate into stricter supervisory expectations.
As stablecoins, tokenized financial products and digital asset services become embedded in mainstream finance, regulatory frameworks are no longer playing catch‑up with a niche industry. Instead, they are defining the terms on which the next iteration of the financial system will operate – and Europe’s MiCA overhaul, set against the backdrop of the U.S. GENIUS Act, is emerging as one of the key battlegrounds where those terms are being written.
