解析美國《GENIUS》穩定幣法案！市場規模上看 3.7 兆美元，三大亮點一次看

The passage of the U.S. GENIUS Act marks a pivotal moment in the evolution of digital finance. With the Senate approving the legislation by a decisive 68–30 vote on June 17, the United States is moving closer to establishing its first comprehensive regulatory framework for stablecoins—laying the foundation for leadership in the global cryptocurrency landscape. While the final version of the law awaits reconciliation between the Senate and House, the momentum behind this legislation signals a strategic shift in how digital assets are perceived and governed.

This article dives into the core aspects of the GENIUS Act, analyzes its implications for financial innovation, and explores why experts project the stablecoin market could reach $3.7 trillion by the late 2030s. We’ll examine three critical highlights—stablecoin definition, issuance standards, and interest distribution rules—and unpack the broader economic and geopolitical motivations driving U.S. policy.

What Is the GENIUS Act?

The GENIUS Act (short for Generative, Efficient, New, Innovative, and Upgraded Stablecoins) represents a landmark effort to bring clarity and structure to the rapidly expanding stablecoin ecosystem. Unlike previous fragmented approaches, this bill proposes a unified national standard for issuing and regulating dollar-pegged digital currencies.

Key provisions include:

• Mandatory registration of stablecoin issuers with federal authorities.
• Requirement for full 1:1 reserve backing using high-liquidity assets such as cash, bank deposits, U.S. Treasury bills, repurchase agreements, and money market funds.
• Annual audits for issuers managing over $50 billion in market value.
• Strict anti-money laundering (AML) compliance.
• Prohibition on paying interest or other returns to stablecoin holders.
• Legal clarification that compliant stablecoins are not securities, thereby removing them from SEC jurisdiction.

These measures aim to balance innovation with systemic risk mitigation, ensuring that stablecoins enhance rather than threaten financial stability.

Why Stablecoin Regulation Matters

Stablecoins currently account for over 60% of all cryptocurrency transaction volume, with more than 90% pegged to the U.S. dollar. Their role extends beyond speculative trading—they serve as essential tools for cross-border payments, remittances, decentralized finance (DeFi), and everyday digital transactions.

However, without clear regulation, these instruments pose significant risks. As Andrew, Chief Economist at XREX, explains in the Web3 Great Westward Expansion series, stablecoins operate in symbiosis with traditional finance—not as replacements, but complements. If an issuer lacks sufficient reserves or faces liquidity issues during redemption events, it could trigger cascading failures across both crypto and conventional banking systems.

For instance, a collapse similar to the 2022 de-pegging of TerraUSD could be magnified if large-scale payment networks rely on undercollateralized stablecoins. Hence, regulatory oversight ensures transparency, protects consumers, and maintains macroeconomic resilience.

Three Key Highlights of the GENIUS and STABLE Acts

While two major bills are under consideration—the Senate’s GENIUS Act and the House’s STABLE Act—their content overlaps by approximately 95%. Both share a common vision: enabling innovation while enforcing accountability. Below are the three most impactful elements shaping this new era of digital currency.

1. Should Stablecoins Pay Interest?

One of the most debated topics is whether stablecoins should generate yield for holders. Both the GENIUS and STABLE Acts explicitly prohibit issuers from offering interest, dividends, or any form of return.

Andrew argues that stablecoins should function primarily as payment instruments, not investment vehicles. Introducing yield could distort their purpose:

• It may incentivize long-term holding instead of circulation, reducing utility in commerce.
• Profit margins for issuers could shrink due to yield payouts, limiting scalability.
• Regulatory ambiguity increases when tokens offer returns, potentially classifying them as securities.

Yet Winston Xiao (蕭滙宗), Co-Founder and Group Revenue Officer at XREX, offers a nuanced view: “Not all stablecoins are the same.” For example, USDM is fully backed by short-term U.S. Treasuries and distributes yield accordingly. As definitions become clearer, he expects diverse models to emerge—each tailored to specific use cases.

2. Clear Classification and Regulatory Boundaries

A major achievement of both bills is the formal definition of "payment stablecoins"—digital assets designed for transactional use and fully backed by qualifying reserves.

Crucially, both acts declare that compliant payment stablecoins do not qualify as securities, placing them outside the jurisdiction of the Securities and Exchange Commission (SEC). Instead, oversight falls to banking regulators like the Office of the Comptroller of the Currency (OCC) and state financial authorities.

This distinction streamlines compliance and reduces legal uncertainty for fintech firms, banks, and retailers exploring stablecoin adoption.

3. Who Can Issue Stablecoins—and What Can Back Them?

The legislation outlines three categories of eligible issuers:

• Federally chartered financial institution subsidiaries.
• Non-bank entities with federal approval.
• State-licensed issuers meeting uniform standards.

Reserve assets must consist exclusively of low-risk, highly liquid instruments:

• Cash and cash equivalents.
• Bank deposits.
• U.S. Treasury securities.
• Repurchase agreements.
• Money market funds.

Importantly, issuers must maintain full 1:1 backing at all times, with reserves held in segregated accounts separate from operational funds. This prevents misuse and ensures immediate convertibility.

Strategic Implications: Strengthening Dollar Dominance

Beyond risk management, the push for stablecoin regulation reflects deeper strategic goals:

🌍 Extending the Digital Reach of the U.S. Dollar

Winston Xiao describes dollar-backed stablecoins as "digital colonies of the U.S. dollar." By enabling global access to USD-denominated digital assets—even outside traditional banking systems—the U.S. reinforces its monetary hegemony in the digital age.

📉 Supporting U.S. Debt Markets

With rising national debt and recent credit downgrades from Moody’s and others, demand for U.S. Treasuries is under pressure. Stablecoins backed by government bonds inject new demand into this market. For example, Tether (issuer of USDT) holds over $120 billion in U.S. Treasuries—making it one of the largest institutional holders.

David Sacks, former White House Crypto Czar, predicts that widespread adoption could drive hundreds of billions in annual demand, helping stabilize long-term interest rates and ease fiscal strain.

🔐 Balancing Centralization and Decentralization

Although today’s stablecoin ecosystem remains largely centralized, its underlying technology supports decentralization. By allowing diverse reserve compositions and non-bank issuers—including tech giants like Amazon, Walmart, Apple, and Google—the GENIUS Act fosters a more distributed yet regulated model.

As Xiao notes: “The right to issue a unit doesn’t have to be monopolized—even if the unit itself is dollar-denominated.”

Frequently Asked Questions (FAQ)
