The world’s second-largest stablecoin, USD Coin (USDC), is undergoing a significant transformation in its reserve composition. In a move aimed at reinforcing trust, transparency, and regulatory compliance, Circle — the company behind USDC — has announced it will now back the stablecoin exclusively with cash and short-term U.S. Treasury securities.
This strategic shift marks a pivotal moment in the evolution of digital finance and reflects growing scrutiny over the asset backing of stablecoins, which play a crucial role in the cryptocurrency ecosystem.
Why Reserve Composition Matters
Stablecoins are designed to minimize the price volatility commonly associated with cryptocurrencies like Bitcoin and Ethereum. By pegging their value to stable assets — typically the U.S. dollar — they serve as reliable mediums of exchange, stores of value, and on-ramps for traders entering the crypto market.
However, the credibility of a stablecoin hinges on what backs it. Historically, Circle claimed that each USDC was fully backed by one U.S. dollar held in reserve. But in July, an attestation report from auditing firm Grant Thornton revealed that only about 60% of USDC reserves were in cash or cash equivalents. The remaining 40% consisted of various debt instruments, including commercial paper and corporate bonds.
While these assets are generally liquid, they carry higher risk than direct cash holdings or government-backed securities.

A New Era of Simplicity and Trust
In response to community feedback, evolving regulatory expectations, and its own commitment to transparency, Circle — together with Coinbase and the Centre Consortium — has simplified USDC’s reserve structure.
As announced in a recent blog post:
"Considering community sentiment, our commitment to trust and transparency, and the changing regulatory environment, Circle, with support from Centre and Coinbase, has announced it will now hold USDC reserves entirely in cash and short-term U.S. Treasury securities."
This means all USDC tokens in circulation are now backed by low-risk, highly liquid assets. U.S. Treasuries are considered among the safest investments globally due to the full faith and credit of the U.S. government. Combined with actual cash holdings, this new reserve model significantly reduces counterparty and credit risk.
These changes are already being implemented and will be reflected in future attestations by Grant Thornton, providing independent verification of the updated reserve composition.
The Competitive Landscape: USDC vs. Tether
USDC currently has approximately $27 billion in circulation, making it the second-largest stablecoin after Tether (USDT), which boasts over $75 billion in outstanding tokens.
Tether has long faced skepticism due to concerns about its reserve transparency. Earlier this year, Tether disclosed that only 2.9% of its reserves were in cash, with the vast majority composed of commercial paper — unsecured short-term corporate debt that carries higher default risk than government bonds.
Such structures raise red flags for regulators and investors alike. A sudden surge in redemption requests could destabilize not only the stablecoin but also broader segments of the short-term credit market.
In contrast, USDC’s pivot toward a fully transparent, low-risk reserve model positions it as a more trustworthy alternative — especially as global regulators tighten oversight on digital assets.
Regulatory Pressure and the Push for Transparency
Regulators worldwide are increasingly focused on stablecoins due to their potential impact on financial stability. The U.S. Federal Reserve has warned that unchecked growth in stablecoins could pose systemic risks.
Fed Chair Jerome Powell has even suggested that a central bank digital currency (CBDC) might eventually reduce reliance on private stablecoins like USDC and Tether.
At the state level, New York Attorney General Letitia James has pushed for greater accountability. As part of an $18.5 million settlement with Tether, her office mandated that the company file quarterly transparency reports — a precedent now influencing industry standards.
Both Tether and Circle have since published detailed reserve breakdowns and pledged to deepen their transparency commitments.
Building Community Governance and Long-Term Trust
Beyond reserve composition, Circle is expanding efforts to involve users in the governance of USDC through the Centre Consortium. Later this year, the organization plans to introduce new mechanisms for community participation in setting standards and shaping policy.
This shift toward decentralized governance aligns with broader trends in blockchain technology — empowering users, increasing accountability, and fostering long-term sustainability.
