EU regulators are preparing a significant rethink of their flagship crypto law, MiCA, as the United States races ahead with new rules for stablecoins under the GENIUS Act. Brussels is now signalling that the first version of MiCA may only be a starting point, with a formal review expected to reshape how stablecoins, tokenized assets and custody services are policed from 2027 onward.
According to officials cited in a recent report, the European Commission plans to reopen key sections of the Markets in Crypto-Assets Regulation in light of the shifting global regulatory landscape. The main trigger: Washington’s Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, which sets out a dedicated framework for dollar-pegged tokens and gives U.S. operators a clearer domestic playbook.
One of the central questions for EU policymakers is how to treat stablecoins issued by firms based outside the bloc, particularly in the United States. MiCA already covers issuers of asset‑referenced tokens and e‑money tokens, but it was written before the GENIUS Act existed. Now, Brussels wants to reassess whether non‑EU stablecoin issuers should face additional conditions, different capital or reserve requirements, or tighter supervision if they want access to the EU’s 450‑million‑person market.
As part of this review, officials are also considering whether MiCA’s scope should be broadened to explicitly cover tokenized payments and tokenized bank deposits. These instruments blur the line between traditional bank money and crypto assets: they may run on blockchain rails, but are often backed one‑to‑one by balances in bank accounts. Regulators worry that leaving such products in a grey zone could open the door to regulatory arbitrage and systemic risk.
Another key goal is legal certainty for U.S. stablecoin issuers seeking to operate across all 27 EU member states. While MiCA was designed to harmonize rules and prevent a patchwork of national regimes, the emergence of robust U.S. federal standards for stablecoins raises practical questions about equivalence, passporting and cross‑border supervision. European policymakers want to avoid a situation where major dollar‑denominated stablecoins fall between regulatory cracks or gain unintentional advantages over euro‑denominated competitors.
These strategic discussions are occurring just as MiCA’s core licensing regime has fully kicked in. Since July 1, any crypto business serving EU customers must secure authorization as a Crypto‑Asset Service Provider (CASP) from a national regulator before offering its services across the bloc. That license is now the legal gateway for exchanges, custodians, brokers and other intermediaries operating in the single market.
Despite MiCA only just becoming fully operational, the European Commission has already launched a formal consultation on how the law should evolve. Often informally referred to as “MiCA 2.0,” this process solicits feedback on areas that were either lightly addressed or left outside the original text, including decentralized finance, stablecoins, advanced tokenization use cases and potential gaps in investor protection. The consultation window is open through the end of August, giving industry, consumer groups and financial institutions a brief period to shape the next iteration.
In parallel, supervisors are tightening their scrutiny of firms already operating under MiCA. The European Securities and Markets Authority (ESMA) announced that it will run an in‑depth review of the operational resilience of licensed CASPs, with a particular focus on custody practices and operational risk. This is a tacit acknowledgement that the biggest immediate vulnerabilities in crypto markets often sit not in the assets themselves but in how platforms safeguard client funds and handle disruptions.
ESMA’s review, scheduled to run from July until the first half of 2027, will examine how CASPs are implementing segregation of client assets, key management, access controls, disaster recovery, and incident response. The findings are expected to feed directly into future amendments to MiCA and into supervisory guidance that could raise the bar for all custodial service providers in Europe.
Meanwhile, developments in the United States are providing both competitive pressure and a regulatory benchmark. In addition to the GENIUS Act, U.S. lawmakers are advancing the Digital Asset Market Clarity Act, a broader bill aimed at defining the market structure for digital assets, including how they are traded and which agencies oversee them. The legislation has already cleared multiple House committees and is expected to head to the Senate floor, with a vote anticipated before lawmakers depart Washington for their summer recess.
Taken together, these parallel moves on both sides of the Atlantic show that crypto regulation is entering a second phase. The first wave focused on bringing exchanges and issuers into a licensing regime; the next is about fine‑tuning those rules for a world in which stablecoins, tokenized securities, on‑chain deposits and digital asset services are no longer peripheral experiments but increasingly integrated into mainstream finance.

What the MiCA rethink actually means for stablecoins
For stablecoin issuers, the EU’s planned review sends a clear signal: compliance expectations are likely to rise, not fall. MiCA already places strict obligations on issuers of asset‑referenced tokens and e‑money tokens, including reserve requirements, governance standards and whitepaper disclosures. The GENIUS Act, however, introduces a new comparative baseline, especially for dollar‑backed stablecoins.
European regulators will now have to decide whether to align certain elements of MiCA with the U.S. approach or deliberately diverge. Convergence could make cross‑border operations easier for large issuers, allowing them to standardize their legal and technical frameworks across the two biggest developed markets. Divergence, by contrast, might reflect different policy goals, such as stronger consumer safeguards in the EU or explicit support for euro‑denominated tokens as a tool of monetary sovereignty.
Non‑EU issuers can expect closer scrutiny in several areas: the quality and location of reserves, transparency over audits, redemption rights for users, and the governance arrangements for key functions such as minting and burning. The more systemically important a stablecoin becomes for European payments and markets, the more likely it is to face bank‑like oversight.

Tokenized payments and deposits: the next regulatory frontier
The potential expansion of MiCA to cover tokenized payments and deposits reflects a broader shift in how regulators think about “digital money.” Under traditional frameworks, bank deposits, electronic money and payment instruments sit squarely within banking and payments law. But once those same instruments are represented as tokens on a distributed ledger, the legal categorization becomes less obvious.
Banks and fintechs are increasingly experimenting with tokenized deposits that can move on blockchain networks while still being fully backed by balances in regulated bank accounts. From a user’s perspective, these tokens can resemble stablecoins. From a regulatory perspective, they may straddle multiple regimes at once: banking rules, payments law and crypto‑asset regulation.
By considering an explicit extension of MiCA to these products, the EU is trying to avoid overlapping or conflicting rules and to ensure that similar risks are treated similarly. That might mean new definitions, tailored disclosure obligations or bespoke prudential requirements for institutions that issue tokenized bank money at scale.

Custody under the microscope
The intensified focus on custody is a reaction to a long series of failures, hacks and mismanagement cases in the crypto sector. Even with MiCA’s baseline requirements, regulators recognize that operational risk in custody – from poor key management to inadequate segregation of assets – can instantly undermine all other safeguards.
ESMA’s multi‑year review is likely to probe several questions:
– Whether CASPs truly keep client assets legally and operationally separate from their own;
– How firms design and test internal controls for private key storage;
– The robustness of contingency plans for cyberattacks, technical failures or insolvency;
– The real‑world effectiveness of insurance or compensation schemes in case of loss.
Depending on the findings, the EU could mandate stricter standards aligned more closely with those in traditional securities custody, such as clearer liability rules for custodians and more granular reporting around asset locations and control.

The transatlantic race for influence in digital assets
The regulatory dance between the EU and the U.S. is also about competitive positioning. Whoever sets the most credible, comprehensive and workable rules for digital assets first may gain outsized influence over how the global industry is structured. MiCA initially gave Europe a head start by creating a unified market with a single set of rules. The GENIUS Act and companion U.S. bills now challenge that lead, at least in the crucial stablecoin segment.
For global firms, the emerging picture is both complex and promising. A clearer rulebook in both the EU and the U.S. reduces the legal uncertainty that has plagued the sector. But it also ends the era where companies could operate in regulatory grey zones for years. Business models will need to be architected with cross‑border compliance at the core, not as an afterthought.

What this means for crypto firms operating in or targeting the EU
Companies already licensed as CASPs – or planning to apply – should be treating MiCA as a moving target rather than a static rulebook. Several practical implications follow:
– Licensing strategies need to anticipate possible MiCA 2.0 changes, especially for firms providing custody, stablecoin services or tokenized financial products.
– Compliance teams should monitor both the formal consultation and ESMA’s review timeline, as supervisory expectations may tighten before legal texts are formally amended.
– Business models heavily reliant on non‑EU stablecoins should be stress‑tested against scenarios in which access to those tokens becomes more restricted or more tightly supervised in the EU.
– Technical infrastructure, particularly around custody, should be upgraded with the assumption that standards will converge toward traditional financial market norms.
Firms that invest early in robust governance, transparent reserves and institutional‑grade security are likely to find the transition smoother than those that aim for the bare minimum.

Potential impact on DeFi and tokenized finance
Although MiCA was not built specifically for decentralized finance, the current consultation explicitly asks whether DeFi requires tailored rules. As stablecoins and tokenized deposits become central collateral and settlement instruments for DeFi protocols, new regulations on those building blocks will indirectly shape the entire ecosystem.
If large, regulated stablecoins are required to limit exposure to certain types of protocols or to adhere to strict on‑chain compliance mechanisms, that could accelerate the emergence of “regulated DeFi” segments running largely on permissioned rails. Conversely, if the EU allows composability with permissionless protocols under defined safeguards, Europe could become a leading jurisdiction for institutional DeFi experimentation.
Either way, the interaction between MiCA, stablecoin rules and emerging market‑structure laws like the U.S. Digital Asset Market Clarity Act will be critical for anyone building financial primitives on public blockchains.

A maturing regulatory environment, not the end of innovation
Despite concerns within parts of the crypto industry that tighter regulation will stifle innovation, the direction of travel in both the EU and the U.S. suggests something more nuanced. Policymakers appear less interested in banning novel instruments outright and more focused on constraining how they are issued, backed, marketed and integrated into the broader financial system.
Stablecoins, tokenized deposits and digital asset service providers are being nudged toward a world that resembles existing financial regulation, albeit with adjustments for the technological differences. In practice, this may filter out lightly capitalized or poorly governed actors while giving more room for banks, payment firms and serious fintechs to build at scale.
For users, the outcome is likely to be fewer wild‑west offerings and more products that look and feel like ordinary financial services, just with faster settlement and programmable features.

MiCA’s upcoming overhaul, spurred in part by the U.S. GENIUS Act, marks the beginning of this next phase. By 2027, the regulatory map for stablecoins, tokenized money and crypto custody in Europe is likely to look substantially different from today’s first‑generation rules, with cross‑border effects that will reach far beyond the EU’s borders.
