The GENIUS Act Passed. Now the Hard Part Starts.

Ask a treasury manager what they think about stablecoins and you will usually get one of two answers. Either enthusiastic nodding followed by “we are monitoring the space,” which means nothing is happening, or genuine curiosity from someone who has run the numbers and cannot quite justify pulling the trigger yet.

Both responses made sense until recently. Then the US passed the GENIUS Act in July 2025, Europe finished building out MiCA, and about six other major jurisdictions decided more or less simultaneously that stablecoins were a payment instrument, not a crypto experiment, and should be regulated accordingly. The waiting-to-see-what-regulators-do excuse ran out.

Which leaves the more honest question on the table: is stablecoin settlement actually useful for your business, or is it just useful for the kind of business you imagine yourself running in three years?

What the law actually changed

The GENIUS Act is the first federal statute in the United States that creates a comprehensive regulatory framework for fiat-backed stablecoins. It passed the Senate 68 to 30 and the House 308 to 122, with implementing regulations due by July 2026 and enforcement beginning no later than January 2027. For context, that kind of bipartisan margin does not happen often in Washington. It signals something more than politics catching up with technology. It signals that stablecoins have become important enough to regulate seriously.

The core of what the Act does is straightforward. Every stablecoin must be backed one to one with real reserves, audited regularly, and limited to high-quality liquid assets. No algorithmic backing, no creative accounting. The ambiguity that made institutional risk teams nervous for years is, on paper at least, resolved. You know what is behind the token. You know who audited it. You know how to redeem it.

On the compliance side, the Act goes further than many in the crypto world were hoping. FinCEN and OFAC are jointly proposing rules that would treat stablecoin issuers as financial institutions under the Bank Secrecy Act, with full AML obligations attached. The reaction in crypto communities was predictable. The reaction in bank compliance departments was relief. That tension is, honestly, a good sign. It means the regulation is doing something real.

The European side of this is messier

If you operate across the Atlantic, the picture gets more complicated. MiCA has been live since 2024, but its teeth are sharpening. ESMA set a firm authorization deadline of July 1, 2026, after which any issuer operating without full approval will be delisted from EU-regulated markets. That is not a soft guideline with room for interpretation. It is a hard cutoff, and several large stablecoin issuers are still working out what it means for them.

The most notable casualty of that uncertainty is Tether. USDT has dominated stablecoin volume globally for years and remains roughly 58 percent of total supply. But as a foreign issuer, Tether requires a Treasury reciprocity determination to continue serving US businesses, and as of May 2026, that determination has not been issued. For anyone building payment infrastructure that relies on USDT, that is a real operational question, not a theoretical one.

USDC has moved into the gap. The combination of GENIUS Act compliance, institutional custody at BNY Mellon, and BlackRock-managed reserves gives compliance teams the documentation they need to sign off. Whether that makes USDC permanently dominant or just temporarily convenient depends on how the next twelve months of rulemaking plays out.

Where treasury teams actually stand

The regulatory question is mostly answered but the infrastructure question is not.

Visa hit a $4.5 billion annualized stablecoin settlement run rate by January 2026. Stripe acquired Bridge for $1.1 billion. Mastercard acquired BVNK for $1.8 billion. When three of the largest payment companies on earth spend that kind of money within the same window, they are not experimenting. They are placing long bets on where settlement infrastructure is heading, and they are doing it before most of their customers have caught up.

The practical appeal for treasury operations is specific. Traditional cross-border payments involve correspondent banking chains that add cost, time, and a certain amount of mystery to every transaction. Stablecoin rails offer a structurally different path. Delivery-versus-payment settlement, where asset transfer and payment occur simultaneously, becomes practical with stablecoins in a way that is simply not possible with traditional rails. For anyone managing cross-border supplier payments or international payroll, that matters more than it sounds. Eliminating the gap between sending and receiving removes an entire category of risk.

But there is a catch, and it is a straightforward one. Research shows that 70 percent of corporates would be more willing to adopt stablecoins if ERP integrations were readily available. The remaining barrier is not regulatory. It is integration. A payment rail that does not connect to your existing treasury management system is not a payment rail you can use in practice. It is a pilot project with no obvious path to production.

Three ways this plays out

The first scenario is gradual normalisation. Stablecoins become a standard settlement option sitting alongside wire transfers and SEPA, particularly for corridors where traditional rails are slow or expensive. Companies with high payment volumes into Latin America, Africa, and Southeast Asia move first, because the case is clearest where correspondent banking is worst.

The second is a dollar-euro split. The US and EU have both created comprehensive frameworks, and MiCA-compliant euro stablecoins are scaling quickly inside Europe. The result might not be one universal stablecoin rail but two well-regulated ones that cover most of the world’s major trade corridors between them. Not elegant, but functional.

The third scenario is that the integration problem stalls everything. The regulations are clear, the technology works, but finance teams cannot get stablecoins to talk to their ERP systems at the speed and reliability their operations require. Adoption stays concentrated among companies with the engineering resources to build custom connections. Everyone else waits for the middleware to catch up.

Which of those plays out depends less on the regulators and more on the infrastructure layer sitting between the stablecoin rails and the businesses trying to use them.

A closing thought

The GENIUS Act and MiCA did not make stablecoins new. They made them usable in places where, until recently, the legal ground was too uncertain to stand on. That is a meaningful change, but it is the beginning of a practical problem, not the end of one.

At Payoro, we already operate a hybrid model that connects stablecoin and crypto liquidity directly to regulated fiat payout infrastructure. A platform distributes digital assets to its users, and Payoro handles the conversion and delivery to their local bank account through a single API, with compliance built into the same flow. The underlying rail, whether fiat or on-chain, becomes largely invisible to the end user.

The regulation settled the question of whether stablecoins belong in serious payment infrastructure. The question now is who builds the layer that makes them actually work.
