The U.S. Senate passed the GENIUS Act on May 20, marking a pivotal step toward formal regulation of stablecoins in the United States. Officially titled the Guiding and Establishing National Innovation for U.S. Stablecoins Act, this legislation was introduced by Senator Bill Hagerty of Tennessee on February 4, 2025, and approved by the Senate with a 66–32 vote. The bill aims to establish a national regulatory framework for dollar-pegged stablecoins, creating a mechanism that ties digital assets directly to high-liquidity U.S. financial instruments.
Under the GENIUS Act, all stablecoin issuers must back every unit of their tokens with either one-to-one reserves in U.S. dollars or short-term U.S. Treasury securities. This ensures that each stablecoin in circulation is fully collateralized by safe, liquid assets. Additionally, issuers will be required to obtain approval from federal or state regulators and remain under continuous oversight. If the bill passes the House and becomes law, it would centralize stablecoin licensing at the federal level—effectively integrating crypto assets into the framework of U.S. sovereign credit.
What Are Stablecoins?
Stablecoins are blockchain-based cryptocurrencies designed to minimize price volatility by pegging their value to external assets—most commonly fiat currencies like the U.S. dollar. They serve as a critical bridge between traditional finance and the decentralized digital economy.
Before stablecoins emerged, converting fiat money into cryptocurrencies involved cumbersome banking procedures, long settlement times, and high transaction fees. Stablecoins streamline this process, enabling fast, low-cost transfers between fiat and digital assets while maintaining price stability.

The Dollar Peg: How Stability Is Maintained
The most widely adopted stablecoins—such as USDT (Tether) and USDC (USD Coin)—maintain a 1:1 parity with the U.S. dollar and are often backed by short-term U.S. Treasury bills maturing within 93 days. This reserve structure links cryptographic tokens directly to America’s most liquid financial instruments.
By anchoring stablecoins to Treasury securities and cash, these digital tokens gain credibility and stability. In turn, they extend the reach of the U.S. dollar into the global crypto ecosystem, enhancing its role as the dominant reserve currency in both physical and digital domains.
This linkage also indirectly boosts liquidity across the broader cryptocurrency market. When volatile assets like Bitcoin or Ethereum are traded against stablecoins instead of fiat, market efficiency improves due to faster settlements and reduced counterparty risk.
Core Mechanisms Behind Stablecoin Design
There are several models for maintaining price stability in stablecoins:
- Fiat-Collateralized: Tokens like USDT and USDC are backed 1:1 by dollar-denominated reserves held in regulated financial institutions. Independent audits verify these holdings periodically.
- Crypto-Collateralized: Examples include DAI, which is over-collateralized using other digital assets such as ETH. Smart contracts manage collateral ratios and liquidations automatically.
- Algorithmic (Non-Collateralized): These rely on supply-adjustment algorithms to maintain pegs, though they have proven less reliable during market stress—highlighted by the collapse of UST in 2022.
The GENIUS Act focuses specifically on fiat-backed stablecoins, mandating full reserve requirements and transparent custodianship to prevent systemic risks.
Stablecoins as Financial Infrastructure
From a monetary perspective, stablecoins function as digital payment rails—modern financial infrastructure enabling seamless value transfer across borders.
By taking an early lead in regulating stablecoins, the U.S. positions itself to dominate the future of cross-border payments and global settlement systems. If international trade increasingly adopts regulated dollar-backed stablecoins, traditional banking intermediaries could be bypassed, dramatically reducing transaction costs and settlement times.
In 2024 alone, global stablecoin users surpassed 120 million, with USDT and USDC serving as primary gateways for converting fiat into crypto markets. Together, they account for over $100 billion in market capitalization, illustrating their growing systemic importance.
Risks and Regulatory Challenges
Despite their benefits, stablecoins carry significant risks:
- Reserve Risk: A sharp decline in Treasury prices or a loss of confidence in reserve audits could trigger a run on stablecoins.
- Systemic Spillover: Given their integration with decentralized finance (DeFi), a failure in one major stablecoin could ripple through lending platforms and exchanges.
- Misuse Potential: Without proper oversight, stablecoins could facilitate money laundering or sanctions evasion through regulatory gaps.
The GENIUS Act addresses many of these concerns by imposing strict transparency, capital adequacy, and supervisory requirements—aligning stablecoin operations more closely with traditional banking safeguards.
Global Implications and Strategic Competition
The passage of the GENIUS Act signals a strategic move by the U.S. to embed its monetary influence deeper into the digital economy. By tying stablecoins to Treasury debt, the U.S. expands demand for its sovereign assets while reinforcing dollar dominance in global finance.
However, this development also raises questions about motivations. With prominent political figures and administration officials expressing personal interest in crypto assets, some analysts question whether this regulatory push serves broader national interests—or specific private agendas.

China's Response: Digital Yuan and Multilateral Bridges
While the U.S. advances its regulatory framework, China continues to develop its own digital currency strategy. The e-CNY (digital yuan) has been piloted extensively in retail and enterprise scenarios, including supply chain financing and cross-border trade settlements.
Additionally, China participates in the mBridge project—a multilateral central bank initiative exploring cross-border payments using digital currencies among emerging economies. Unlike dollar-pegged stablecoins, mBridge emphasizes interoperability between sovereign digital currencies without reliance on any single reserve asset.
Domestically, Chinese firms are experimenting with enterprise credit-backed stable tokens, where supply chain receivables serve as collateral. Some commercial banks even offer custodial services for these instruments—an innovative fusion of traditional finance and tokenization.
These efforts suggest that while the U.S. leverages private-sector innovation within a regulated framework, China focuses on state-led digital currency deployment with deep integration into real-economy use cases.
Frequently Asked Questions (FAQ)
Q: What is the GENIUS Act?
A: The GENIUS Act is U.S. legislation designed to regulate dollar-backed stablecoins by requiring full reserves in short-term Treasuries or cash and mandating federal oversight for all issuers.
Q: Are stablecoins safe?
A: Regulated fiat-collateralized stablecoins like USDC and USDT are generally considered low-risk when reserves are audited and transparently managed. However, risks remain if reserves are mismanaged or market conditions deteriorate.
Q: How do stablecoins affect the U.S. dollar?
A: By increasing global demand for dollar-denominated assets like T-bills, stablecoins enhance the dollar’s international usage and generate digital seigniorage benefits.
Q: Can stablecoins replace traditional banking?
A: While they can supplement payment systems—especially cross-border ones—they are unlikely to fully replace banks soon due to regulatory, scalability, and trust constraints.
Q: What’s the difference between CBDCs and stablecoins?
A: Central Bank Digital Currencies (CBDCs) like e-CNY are issued by central banks and represent direct liabilities of the state. Stablecoins are typically issued by private entities but may be pegged to fiat currencies.
Q: Will the GENIUS Act become law?
A: It has passed the Senate but must still clear the House of Representatives. If enacted, it would set a precedent for federal-level crypto asset regulation in the U.S.
Stablecoins represent more than just a technological innovation—they are redefining how value moves in a digitized world. As nations compete to shape the rules of this new financial frontier, the interplay between regulation, monetary policy, and technological adoption will determine who leads the next era of global finance.
