Digitalizing Dominance: How the GENIUS Act Reinforces U.S. Dollar Hegemony

Stablecoins once alarmed Washington as a threat to the dollar. The GENIUS Act, enacted in July 2025, flips that script. The law seeks to transform stablecoins into a digital pillar of U.S. financial power—shoring up trust in dollar-denominated tokens, steering demand toward U.S. government debt, and widening foreign access to dollars.

From Regulatory Wilderness to Digital Order

Before the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, Pub. L. No. 119-27 (2025), stablecoins operated in what was often described as a "Wild West." With minimal regulatory oversight, some stablecoin issuers marketed their tokens as "stable" or "dollar-pegged" while freely plowing consumers' reserve funds into speculative assets, diverting funds to affiliates, and hiding material information. Stablecoin consumers lacked legal protection.

Regardless, demand surged. Stablecoin market capitalization exploded from less than $1 billion in 2017 to $258 billion in August 2025. On-chain data revealed that stablecoin transactions totalled an estimated $3.7 trillion in 2023 and $2.62 trillion in the first half of 2024 alone. Crucially, about 99 percent of stablecoin value claimed a peg to the U.S. dollar—though whether sufficient reserves actually backed that promise was often opaque. A new asset class emerged: the de facto "digital dollar."

Policymakers saw both the promise and the risks in this new, private, lightly regulated, and global asset class. A run on stablecoins could shake foreign confidence in the U.S. dollar and spark contagion in the U.S. financial system. At the same time, if foreign regulators moved first to define and supervise these instruments, they could set the rules for a growing slice of dollar‑based activity. To preempt foreign governments from setting standards for dollar‑pegged stablecoins, policymakers enacted the GENIUS Act, imposing U.S. requirements instead.

Building a Domestic Regulatory Fortress

Scholars Gary Gorton and Jeffery Zhang have compared pre-regulation stablecoins and the wildcat banks of nineteenth-century America—institutions that issued notes of uncertain value backed by questionable assets, and were vulnerable to runs. The National Bank Acts of the 1860s responded by requiring federal charters, setting reserve rules, and requiring that notes be backed by U.S. government securities. The GENIUS Act plays a parallel role for stablecoins, imposing a uniform regulatory framework on a new financial market.

GENIUS creates a new, legally defined category of “permitted payment stablecoins,” issued only by licensed “permitted payment stablecoin issuers” in the United States. Among the Act’s many provisions, five interlocking requirements are central to making permitted payment stablecoins a robust medium of exchange.

1. Hard asset backing, one-to-one. Section 4(a)(1) mandates that every dollar of permitted payment stablecoins be matched one-to-one by high-quality liquid assets—principally Treasury securities with maturities of 93 days or less, overnight repurchase agreements collateralized by government securities, shares in government money-market funds, demand deposits at U.S. banks, and U.S. coins and notes. The rule shuts down several practices that were common among some issuers before GENIUS, such as running with less than full reserves or holding large amounts of commercial paper and corporate bonds in reserve portfolios. Those assets can lose value or become illiquid in periods of market stress. By narrowing eligible reserves to the safest, most liquid dollar‑denominated assets, GENIUS sharply limits credit, interest‑rate, and liquidity risk for permitted payment stablecoins.
2. Rehypothecation ban. Section 4(a)(2) bars permitted payment stablecoin issuers from re-pledging reserve assets as collateral or lending them out. This cuts off a major channel through which stablecoin reserves may otherwise be pulled into leveraged markets. 
3. Transparency and liability. Sections 4(a)(1) and 4(a)(3) require both the CEO and CFO of permitted payment stablecoin issuers to make a monthly declaration regarding the accuracy of reserves examined by a public accounting firm, and to publish reserve information on the issuer’s website. The CEO and CFO face criminal liability for knowingly false certifications. This replaces the voluntary attestations and unaudited claims that characterized the pre‑Act era, giving both users and regulators a clearer view of the assets backing digital dollars.
4. Bankruptcy remoteness. Sections 10 and 11 mandate segregated custodial accounts, granting permitted payment stablecoin holders first‑priority claims on reserves. If an issuer enters bankruptcy, token holders stand ahead of general creditors. GENIUS thus aims to protect par redemption for stablecoin holders in the event of issuer insolvency.
5. Focus on Medium of Exchange. Section 17 clarifies that permitted payment stablecoins are neither securities nor commodities. Combined with the ban on pledging reserve assets as collateral and Section 4(a)(11)’s prohibition on paying interest to holders, these provisions reduce the likelihood that GENIUS‑compliant coins evolve into complex money‑market substitutes or shadow‑banking vehicles, ensuring they remain a robust medium of exchange. 

Exorbitant Privilege 2.0: The Captive-Buyer Mechanism

The GENIUS Act’s most strategically significant feature lies in what it compels permitted payment stablecoin issuers to hold as reserves: U.S. government debt. Under Section 4(a)(1) reserve rules, permitted payment stablecoin issuers must hold large quantities of short‑term Treasury securities as backing assets. As global demand for dollar stablecoins grows, transactional demand for digital dollars becomes structural demand for U.S. government debt.

This is a digital update of what Valéry Giscard d'Estaing dubbed America's "exorbitant privilege." Over the last two decades, foreign central banks and institutional investors held about one-third to half of Treasury securities. Under GENIUS, a new class of indirect retail buyers emerges: permitted payment stablecoin issuers. A merchant in Lagos accepting permitted payment stablecoins, a remittance recipient in Manila holding them rather than converting to pesos, and a Venezuelan family preserving savings via them—all become indirect purchasers of Treasury securities: they will never bid at an auction, but their demand for stablecoins forces issuers to hold those securities continuously. With stablecoin market capitalization already exceeding $258 billion and Standard Chartered Bank projecting that it could reach $2 trillion by 2028, GENIUS would bypass foreign central banks entirely, channeling demand for Treasury securities through end users worldwide.

From a fiscal perspective, total outstanding U.S. Treasury securities stood at $30.1 trillion as of November 30, 2025, of which foreign investors hold approximately one-third. This share has declined steadily—foreign investors held roughly half of Treasury securities outstanding a decade ago. Given these dynamics, the captive-buyer channel for dollar-pegged stablecoins would only marginally help refinance U.S. government debt. It is not a fiscal panacea.

Banking the Unbanked with Digital Dollars

The GENIUS Act's implications extend beyond financial markets to the geography of money. According to the World Bank Global Findex, approximately 1.3 billion adults worldwide lack a bank account. Yet smartphone penetration in emerging markets increasingly exceeds bank-branch access, creating infrastructure for digital financial services that bypass traditional banking entirely.

Dollar dominance rests on network effects: the more people invoice, save, and settle in dollars, the more attractive dollars become for others. GENIUS enhances these network effects by making permitted payment stablecoins trustworthy and more accessible to billions of smartphone users outside the reach of conventional banking.

Survey data from Brazil, India, Indonesia, Nigeria, and Türkiye illuminate the depth of stablecoin adoption in these markets. 38 percent of users have converted local currency into stablecoins at least once. 47 percent save in dollars through stablecoins. 69 percent have made cross-border money transfers, and 23 percent have received or paid a salary in stablecoins. These figures capture not speculative traders but households and small businesses seeking stability. Adoption is accelerating—57 percent increased usage in the prior year, and 72 percent expect further increases.

The advantages of digital dollars show up quickly. A Kenyan entrepreneur can receive payment from a British customer in seconds rather than days, holding the proceeds in a dollar-denominated wallet without needing a correspondent banking relationship. An Indian overseas worker can send remittances home through a mobile app, bypassing high-fee money transfer operators.

Digital Dollarization and Geopolitics

As dollar‑denominated stablecoins continue to spread, we may begin to see de facto digital dollar zones—environments where a large share of savings, payments, and cross‑border transactions settle in dollar‑based tokens rather than in local currencies. For other countries, digital dollarization brings capital flight, balance‑sheet dollarization, and weaker monetary policy autonomy. For the United States, digital dollarization presents an opportunity: a wider, more deeply integrated dollar area with fewer frictions for cross‑border commerce and greater diplomatic leverage over financial chokepoints.

Foreign policymakers have started to recognize these international political dynamics. The European Central Bank (ECB), for instance, has warned that large‑scale stablecoin adoption could spawn “digital currency areas”—networks transacting predominantly in a specific digital currency. What the ECB portrays as a threat to European monetary autonomy reads, from Washington’s perspective, as an expansion of U.S. monetary influence.

GENIUS also arms U.S. policymakers with tools of financial statecraft to promote digital dollarization worldwide. Sections 3(b)(2), 8, and 18 give the executive branch standing authority to gatekeep foreign stablecoin issuers’ access to the American financial system and, if necessary, cut them off—creating enduring tools of financial coercion, akin to SWIFT. These sections create a powerful carrot-and-stick structure: hostile actors are locked out of the U.S. stablecoin market, while foreign players willing to operate on U.S. terms are allowed to join. Once inside, they benefit from a market supercharged by Section 16, which clears regulatory barriers for banks and credit unions to enter the U.S. stablecoin market. As traditional banking integrates with the digital dollar, old‑economy capital pours into this new‑economy asset class—cementing U.S. stablecoin dominance. In short, GENIUS actively projects U.S. monetary and regulatory power deeper into other countries.

For countries facing persistently high inflation, weak institutions, or chronic currency depreciation, GENIUS‑enabled stablecoins sharpen longstanding dollarization pressures. Residents there may shift savings into dollar-denominated stablecoins at scale, treating them as a convenient, U.S.-legally protected channel for holding dollars outside their own banking systems. Even though these stablecoins pay no interest, they are perceived as safe and liquid, and their 24/7 portability can make them attractive relative to fragile local deposits and volatile local‑currency assets. From the U.S. perspective, such digital dollarization extends the reach of dollar finance. For affected countries, it complicates national monetary policy, erodes the local currency’s role as a store of value, and constrains the effectiveness of capital controls—tilting the geography of money further toward American legal and financial infrastructure.

New Vulnerabilities

While the GENIUS Act reinforces the dollar’s global dominance, it exposes new vulnerabilities.

1. Interest-ban evasion. Issuers or third‑party platforms may seek to develop features that approximate a yield experience—for example, arrangements that pass through interest via cryptocurrency platforms, whose legality under Section 4(a)(11) remains untested. 

2. Cross‑border spillovers. Rapid stablecoin adoption abroad could complicate other countries' monetary policy and heighten geopolitical tensions, especially where digital dollarization intersects with sanctions disputes.

3. Run and contagion risk. Even with high‑quality reserves, large‑scale stablecoin redemptions during market stress could force rapid asset sales that ripple through money markets. The Act’s hard reserve requirements, rehypothecation bans, bankruptcy‑remoteness provisions, and frequent disclosures reduce the likelihood and severity of runs but do not eliminate them. 

4. Banking disintermediation. Large‑scale substitution of deposits into stablecoins could raise banks’ funding costs and strain credit supply. That risk is mitigated by the Act’s prohibition on interest‑bearing stablecoins.

While the captive‑buyer mechanism can modestly generate new demand for Treasuries, it cannot substitute for disciplined fiscal policy.

Conclusion

The GENIUS Act turns a potentially centrifugal technology into a centripetal one, pulling users, transactions, and reserves toward U.S. standards and assets. As money becomes more digital and global, GENIUS anchors it in American institutions and legal frameworks. Through domestic regulation, a captive-buyer mechanism for U.S. government debt, and the projection of U.S. standards into cross-border payments, GENIUS offers a blueprint for digital-age monetary statecraft that reinforces dollar hegemony.
