Why Global Stablecoin Rules Need G20 Alignment to End Market Fragmentation

The think tank argues the G20, convening in December under a US presidency that has placed digital finance on its economic agenda, should move beyond broad commitments toward mutual recognition, common usage rules, and economic fungibility.

Divergent Frameworks, Duplicate Costs

The US GENIUS Act and the EU's Markets in Crypto-Assets regulation anchor the current fragmentation. Under GENIUS, foreign issuers can offer payment stablecoins in the US without a full domestic license, provided the Treasury Department determines the issuer's home regulatory regime is comparable. MiCA provides no equivalent pathway: it requires issuers to be locally established and regulated. Both regimes also mandate that issuers hold at least some reserves with local financial institutions, adding a further practical hurdle for foreign entrants.

The structural result: global stablecoin issuers must operate through two separate, locally licensed entities to serve both US and EU markets. Licensing, capital, reserve, and attestation requirements are duplicated. Compliance and examination overhead compounds. As additional jurisdictions introduce their own rules, the cost curve steepens.

Three Coordination Priorities

The Atlantic Council identifies three priorities for the Miami summit:

• Mutual recognition of stablecoin issuers across jurisdictions
• Common rules governing stablecoin use in payments, settlement, and collateral
• Economic fungibility, ensuring stablecoins issued under different regimes are treated as equivalent across borders

Progress across all three is described as necessary if stablecoins are to deliver on faster and cheaper cross-border payments. The G20's limited progress on its own cross-border payment targets underscores the coordination gap. Even where an issuer can offer its stablecoin across jurisdictions, users require legal and commercial certainty that the asset will be recognized locally for payments, settlement, and collateral purposes.

Market Activity Amid the Gap

Institutional activity continues regardless of the regulatory ambiguity. JPMorgan Chase is reportedly evaluating the feasibility of launching its own backed digital currency amid expanding bank alliances and evolving US frameworks. Western Union has targeted May for the launch of its USDPT stablecoin. World Liberty Financial has announced plans to issue its USD1 stablecoin natively on the Canton Network. Each new entrant adds pressure for interoperability standards, and raises the cost of inaction on mutual recognition.

For USDT and other established issuers, the math is direct. Collateralization, attestation, and reserve-placement obligations now scale with each additional regulatory regime a product touches. A G20 move toward comparable-regime determinations would reduce duplicative capital requirements and consolidate fiat-equivalent liquidity across borders. Without it, issuance architecture continues to bifurcate, and the cross-border fungibility that defines a payment stablecoin's utility outside a single jurisdiction remains structurally constrained.
