The World Economic Forum has published a side-by-side comparison of the United States' GENIUS Act and the European Union's Markets in Crypto-Assets Regulation (MiCA). The exercise frames the two laws as the defining digital-asset rulebooks outside Asia, though its substance rests on legislative texts rather than enforcement records.

The timing matters. MiCA's stablecoin provisions took effect on June 30, 2024, with the remainder of the regulation applicable from December 30, 2024. The GENIUS Act advanced through the U.S. Senate in mid-2025, but the comparison omits any reference to its House consideration timeline or signing date.

What does each law actually require?

The U.S. GENIUS Act narrows its focus to payment stablecoins. It mandates 1:1 reserve backing in U.S. dollars or short-duration Treasuries, requires monthly public disclosure of those reserves, and offers issuers a choice between a federal bank-like charter and state-level pathways.

MiCA operates on a wider canvas. It divides digital assets into e-money tokens, asset-referenced tokens, and other crypto-assets. Issuers and service providers must register with a national authority, meet capital and conduct standards, and gain a passport to operate across all 27 EU member states.

The takeaway: the U.S. framework concentrates on one instrument; the EU framework regulates the full market.

Where do the regimes diverge most sharply?

The divergence is structural. Reserve composition differs. The GENIUS Act permits Treasuries under ninety days; MiCA prohibits interest on e-money tokens and imposes stringent liquidity, custody, and governance rules on asset-referenced token issuers.

Supervisory architecture also splits. The EU funnels oversight through national authorities and the European Securities and Markets Authority, with a single supervisory college for significant tokens. The U.S. approach divides authority among the Office of the Comptroller of the Currency, the Federal Reserve, and state regulators, a fragmentation the comparison surfaces as a coordination concern.

The takeaway: one supervisor versus three complicates crisis response.

What changes for issuers operating in both jurisdictions?

A firm issuing under both regimes must reconcile reserve accounting, redemption rights, and disclosure cadence in real time. Under MiCA, e-money token holders carry creditor claims redeemable at par at any moment. Under the GENIUS Act, holders receive comparable redemption assurances within a regulator-defined window.

The caveat: neither framework has completed a full enforcement cycle. The published comparison does not address algorithmic stablecoins or decentralized finance protocols. Issuers should treat both regimes as live experiments rather than settled law.

What does the WEF comparison leave unresolved?

The published comparison does not detail the GENIUS Act's House consideration timeline. It offers no cost differential between the two regimes, a figure issuers have repeatedly requested from European supervisors without published response.

What is clear is that the two frameworks now define the outer boundary of Western digital-asset governance, and any firm operating across both must build a compliance function that serves two masters at once.
