The GENIUS Act Gives Stablecoins a Federal Rulebook — and Puts the Payment Rails on Notice

For more than a decade, stablecoins lived in a regulatory grey zone: useful, fast-growing and largely unregulated, they were treated by many mainstream financiers as a curiosity of the crypto fringe. That era ended in Washington this week, when the Senate passed the GENIUS Act by 68 votes to 30, establishing for the first time a federal framework for dollar-pegged stablecoins and creating a sanctioned pathway for private companies to issue digital dollars with the explicit blessing of the federal government. The vote is the crypto industry's first major legislative win, and its consequences will reach far beyond the blockchain community, touching the banks, retailers and payment networks that move money for billions of people every day.

The GENIUS Act — short for the Guiding and Establishing National Innovation for U.S. Stablecoins Act — sets guardrails for an industry that has grown in the shadows. It requires full reserve backing, monthly audits and anti-money-laundering compliance, and it opens the door to a much broader range of issuers, including banks, fintechs and major retailers looking to launch their own stablecoins or fold them into existing payment systems. In doing so, it begins to answer the question that has hung over the sector since its earliest days: who is allowed to issue a digital dollar, and under whose rules?

What the law actually changes

The most important shift is legitimacy. Until now, issuing a stablecoin was something a crypto-native company did, often from offshore, with reserves whose quality and location were a matter of trust rather than law. The GENIUS Act moves that activity into the regulated perimeter of the United States financial system. Full reserve backing means a stablecoin must be matched one-for-one by real assets, and monthly audits mean those reserves must be verifiable on a recurring basis rather than asserted once and forgotten. Anti-money-laundering compliance brings stablecoin issuers under the same know-your-customer and sanctions-screening obligations that banks have long carried.

Equally significant is who may now participate. The legislation opens issuance to banks, fintechs and major retailers, while restricting non-financial large technology companies from issuing stablecoins directly unless they establish or partner with a regulated financial entity — a provision aimed at blunting monopoly concerns. The effect is to invite the very institutions that stablecoins were once pitched against — banks and big retailers — into the business of issuing them, while keeping the largest technology platforms at arm's length unless they work through a regulated partner.

The law also hands sweeping authority to Treasury Secretary Scott Bessent, who told a Senate appropriations subcommittee last week that the US stablecoin market could grow nearly eightfold to more than $2 trillion in the next few years. That projection is the clearest statement yet of how seriously Washington now takes the sector: a market measured in the hundreds of billions today is being planned for as a multi-trillion-dollar pillar of the financial system.

Why payment networks should be paying attention

Stablecoins are a subset of cryptocurrencies pegged to the value of real-world assets, and about 99% of all stablecoins are tethered to the price of the US dollar. Their appeal is practical rather than speculative: they offer near-instant settlement and lower transaction fees by cutting out the intermediaries that sit between a payer and a payee. That is precisely the territory occupied by the card networks and payment processors that have dominated consumer and business payments for decades.

The scale of the threat is already visible in the numbers. Deutsche Bank found that stablecoin transactions hit $28 trillion last year, surpassing the combined transaction volume of Mastercard and Visa. That is not yet consumer spending at the checkout — much of it is trading, treasury movement and settlement between crypto firms — but it shows that the underlying rails can already carry enormous volume. As stablecoins gain a federal rulebook and a wider set of reputable issuers, the distance between that $28 trillion of activity and everyday commerce shrinks.

The industry is already moving. Shopify has rolled out USDC-powered payments through Coinbase and Stripe, bringing stablecoin settlement into a mainstream e-commerce platform. Bank of America's chief executive said last week at a Morgan Stanley conference that the bank is having conversations with the industry and is individually exploring stablecoin issuance. When the largest US banks begin to treat stablecoins as a product line rather than a competitor to be ignored, the competitive landscape for payments changes fundamentally.

The banks' two-track response

Incumbent banks are not waiting to be disrupted; they are choosing how to participate. One path is to issue a stablecoin directly, as the GENIUS Act now permits for regulated financial institutions. The other is to build a parallel instrument that keeps money inside the traditional banking system while borrowing the technology that makes stablecoins attractive. JPMorgan Chase has taken the second route, launching JPMD, a deposit token designed to function like a stablecoin but tightly integrated with the existing banking infrastructure.

Issued on Coinbase's Base blockchain, JPMD is available only to institutional clients and offers features such as 24/7 settlement and interest payments. It is part of a broader push by legacy finance to adapt to the stablecoin era without ceding ground to crypto-native firms. The distinction matters: a deposit token is a claim on a bank, governed by banking rules, whereas a stablecoin is a claim on a reserve held by an issuer. By offering a bank-native version of the same convenience, JPMorgan is betting that institutions will prefer the safety of a regulated balance sheet even as they adopt the speed of tokenised settlement.

This two-track dynamic — crypto-native stablecoins on one side, bank-issued tokens on the other — is likely to define the next phase of the market. The GENIUS Act does not pick a winner; it sets the conditions under which both can operate, and it invites a wide range of players, from community banks to global retailers, to decide which side of the line they want to stand on.

The politics behind the milestone

For all its technical detail, the GENIUS Act is also a political story, and one that reveals how much the crypto industry's fortunes now depend on Washington. The industry put around $250 million into the 2024 election cycle to help elect what is now considered the most pro-crypto Congress in US history, and the bill's passage is a direct payoff on that investment. Senator Kirsten Gillibrand, a Democrat from New York and one of the bill's sponsors, framed the result in terms of national interest: "The GENIUS Act will protect consumers, enable responsible innovation, and safeguard the dominance of the US dollar."

Not everyone agreed. Senator Jeff Merkley, a Democrat from Oregon, accused Republicans of "rubberstamping Trump's crypto corruption" and of allowing the president to sell "access to the government for personal profit." Merkley had pushed an amendment to bar elected officials from personally profiting off digital assets, but said Republican lawmakers blocked every effort to hold a floor vote. In May, Senate Democrats unveiled the "End Crypto Corruption Act," led by Merkley and Minority Leader Chuck Schumer of New York, intended to prohibit elected officials and senior executive-branch personnel and their families from issuing or endorsing digital assets. That effort did not make it into the final bill.

The final legislation bars members of Congress and their families from profiting off crypto ventures, but it stops short of extending that restriction to the president. President Donald Trump's first financial disclosure as president, released the previous Friday, showed he earned at least $57 million in 2024 from token sales tied to World Liberty Financial, a crypto platform closely aligned with his political brand. He holds nearly 16 billion WLFI governance tokens — the crypto equivalent of voting shares — which could be worth close to $1 billion on paper based on prior private sales. The family's wider ventures, including the $TRUMP meme coin, a $2.5 billion bitcoin treasury and proposed bitcoin and ether exchange-traded funds via Truth.Fi, plus a newly launched mining firm called American Bitcoin, reflect an aggressive push into digital finance. Forbes recently estimated Trump's crypto holdings at nearly $1 billion, lifting his total net worth to $5.6 billion.

The political stakes explain why a bill that was supposed to be the easiest crypto legislation to pass took months to reach the Senate floor, failed once, and passed only after fierce negotiation. Senator Cynthia Lummis, a Republican from Wyoming, said at the Bitcoin 2025 conference in Las Vegas: "We thought it would be easiest to start with stablecoins. It has been extremely difficult. I had no idea how hard this was going to be." Senator Bill Hagerty, a Republican from Tennessee, was blunter about the 18 Senate Democrats who ultimately crossed the aisle: "It has been murder to get them there."

What happens next in the House

The Senate's passage is a turning point, but it is not the finish line. The bill still faces hurdles in the Republican-held House, which has its own version of a stablecoin bill dubbed STABLE. Both the Senate and House versions prohibit yield-bearing consumer stablecoins, but they diverge on who regulates what. The Senate's version centralises oversight with the Treasury, while the House splits authority between the Federal Reserve, the Comptroller of the Currency and other agencies. Reconciling the two could take a while, according to congressional aides, and the details of that reconciliation will determine how burdensome — or how permissive — the final regime turns out to be.

The question of yield is one of the most consequential. By barring stablecoins from paying interest to consumers, the law protects a core function of the banking system: banks pay interest on deposits, and that interest is a key reason savers keep money in banks. If stablecoins could pay a competitive yield, they would become a direct substitute for bank deposits, potentially drawing savings out of the regulated banking system. Prohibiting yield preserves that boundary for now, even as it leaves open the possibility that the line will be tested again in future legislation.

The wider rewire of money

Step back from the politics and the technicalities, and the GENIUS Act marks a genuine inflection point in the history of money. For most of the modern era, the movement of value has been controlled by a relatively small set of institutions: central banks that issue currency, commercial banks that hold deposits, and card networks and payment processors that route transactions. Stablecoins introduce a fourth category — privately issued digital dollars that settle on public blockchains — and the GENIUS Act is the moment that category was brought inside the regulatory tent rather than left outside it.

That has implications that go well beyond crypto. It affects how companies manage treasury and settle cross-border transactions, how retailers think about the cost of accepting payments, and how banks defend the deposit base that funds their lending. It also affects the global standing of the dollar: a well-regulated ecosystem of dollar-pegged stablecoins could extend the reach of the US currency into corners of the global economy that traditional banking rails serve poorly, which is one reason supporters frame the law as a way to "safeguard the dominance of the US dollar."

None of this means the card networks disappear overnight, or that stablecoins instantly replace bank deposits. Payment habits are sticky, trust is built slowly, and the new regime will take time to implement. But the direction of travel is now set by law rather than left to chance. The GENIUS Act does not merely regulate an existing market; it authorises the construction of a new one, and it invites the most powerful institutions in finance to compete for a share of it.

What to watch next

• How the House reconciles its STABLE bill with the Senate's GENIUS Act, and whether oversight stays centralised at the Treasury or is split among several regulators.
• Whether major banks move from exploring stablecoin issuance to actually launching products, and how quickly retailers follow.
• The growth of the stablecoin market toward the multi-trillion-dollar scale that Treasury Secretary Scott Bessent projected, and whether that growth comes from trading, treasury use or everyday commerce.
• Whether the prohibition on yield-bearing consumer stablecoins holds, or whether a future Congress revisits the boundary between stablecoins and bank deposits.
• How payment networks such as Visa and Mastercard respond to a rival rail that already carries more annual transaction volume than the two of them combined.

The GENIUS Act is the rare piece of financial legislation that both creates a market and redraws the map of an existing one. Its passage in the Senate is the crypto industry's biggest win to date, but its real significance lies in what it authorises: a federally sanctioned, reserve-backed, audited digital dollar, issued by banks and retailers as readily as by crypto firms. The payment rails that have carried the world's money for half a century are not being torn up — but for the first time, they have a serious, regulated competitor, and the rules of the road have just been written.
