USDC (USD Coin) is a stablecoin pegged 1:1 to the U.S. dollar. Launched by Circle in 2018, it aims to provide the cryptocurrency market with a stable, blockchain-based payment solution. Key characteristics include:
- Value Stability: Each USDC is fully backed by reserves composed of cash and short-term U.S. Treasury bonds. These reserves undergo monthly independent audits to ensure transparency.
- Regulatory Compliance: Circle, the issuer of USDC, is registered as a Money Services Business (MSB) with the U.S. Department of the Treasury. It also holds money transmitter licenses in multiple U.S. states and strictly adheres to Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements.
- Use Cases: USDC is widely used in cross-border payments, DeFi lending, and trading. By 2025, it is projected to capture up to 30% of the DeFi stablecoin market.
Compared to other stablecoins like USDT, USDC is often regarded as more transparent and compliant. Approximately 80% of its reserves are held in U.S. Treasury bonds, with the remaining 20% in cash. All audit reports are publicly accessible. In contrast, USDT has faced regulatory scrutiny and concerns regarding reserve transparency.
The U.S. GENIUS Act: Reshaping Stablecoin Regulations
In May 2025, the U.S. Senate passed the GENIUS Act (Guidance for Establishing National Innovation for the U.S. Stablecoins Act). This legislation marks a significant shift in how stablecoins are regulated. Major provisions include:
- Strict Reserve Requirements: Stablecoins must be fully backed by cash, U.S. Treasury bonds, and other highly liquid assets. Rehypothecation or misuse of reserves is prohibited.
- Tiered Regulatory Oversight: Issuers with a market capitalization exceeding $100 billion (such as USDC and USDT) are subject to direct federal supervision. Smaller entities fall under state-level regulation.
- Transparency and Compliance: Monthly disclosure of reserve composition is mandatory, along with third-party audits. Interest-bearing and purely algorithmic stablecoins are restricted.
- Strengthening the U.S. Dollar: The bill explicitly supports USD-backed stablecoins in competing with other digital currencies, such as China’s digital yuan and stablecoins regulated under the EU’s MiCA framework.
Direct Implications for USDC
- Enhanced Competitive Advantage: USDC’s existing reserve structure already meets the new legal requirements. This positions it as a preferred stablecoin for institutional adoption, potentially expanding its market share.
- Increased Market Competition: The legislation limits large tech firms (like Meta and Amazon) from issuing stablecoins. It also raises compliance costs for foreign issuers (including Tether), creating growth opportunities for USDC.
- Pressure for Innovation: Decentralized stablecoins (e.g., DAI) may need to adjust their reserve models toward greater U.S. Treasury backing. USDC, being centralized, may adapt more easily to these regulatory changes.
Future Outlook: Opportunities and Challenges for USDC
Opportunities
- Institutional Adoption: Clear regulations may encourage traditional financial institutions—such as banks and brokerages—to enter the stablecoin market. USDC could become their preferred partner due to its compliance.
- Global Payment Expansion: Regulatory clarity can promote the use of USDC in cross-border payments and supply-chain financing. Major players like JPMorgan have already explored blockchain-based settlements using USDC.
- DeFi Ecosystem Growth: Increased stablecoin trading volumes may benefit DeFi protocols like Curve and Aave, indirectly boosting on-chain demand for USDC.
Challenges
- Rising Compliance Costs: Monthly audits and disclosure requirements could increase operational costs. While smaller issuers may struggle, USDC’s scale may help it absorb these expenses.
- User Redemption Rights: Although the law prioritizes user redemption rights, USDC’s current terms require individual users to redeem tokens indirectly through exchanges. This may raise legal and operational concerns.
- Regulatory Uncertainty: The bill must still pass a final Senate vote. Political and industry interests (such as projects like Trump USD1) could influence its implementation.

Yes, USDC is widely integrated into DeFi protocols for lending, borrowing, and trading. Its compliance with new regulations may increase its adoption in decentralized applications.
Is USDC safer than USDT?
USDC is often considered more transparent due to its regular public audits and compliance with U.S. regulations. However, both stablecoins carry distinct risks related to reserves and regulatory treatment.
What are the reserve requirements under the new law?
Stablecoins must be 100% backed by cash, U.S. Treasury bonds, or other highly liquid assets. Issuers must also undergo monthly third-party audits.
How will the GENIUS Act impact global stablecoin competition?
The act aims to strengthen the position of USD-backed stablecoins like USDC in international markets, particularly against alternatives such as the digital yuan and EU-regulated stablecoins.
Conclusion: The New Stablecoin Landscape Under Regulation
The GENIUS Act represents a move toward normalized, regulated growth for stablecoins. For USDC, its commitment to compliance and transparency may serve as both a defensive moat and a growth driver. As traditional finance and cryptocurrency ecosystems continue to merge, USDC is likely to play an critical role in cross-border payments, settlements, and DeFi.
However, regulatory developments and competitive pressures remain uncertain. Investors and users should stay informed about the implementation of the law and ongoing industry feedback.
