Rating Downgraded to Lowest Tier, Market Concerns Intensify
Recently, S&P Global, an international rating agency, released an evaluation report pointing out that the ability of the USDT issued by Tether to maintain its stablecoin peg has been downgraded to the "weak" level in its five-tier system, attracting broad industry attention. As the largest stablecoin by market value, USDT holds a pivotal position in global crypto asset trading and cross-border capital flows, making the rating change especially impactful on market sentiment.
Analysts indicate that this downgrade not only directly questions Tether's asset management structure but also reflects sustained concern from regulatory and traditional financial institutions regarding stablecoin risk exposure. As stablecoins continue to expand their influence in mainstream payment and investment channels, their transparency and compliance are regarded as increasingly important systemic factors.
Decline in Collateral Ratio Raises Payout Ability Concerns
The S&P report shows that the circulation of USDT has approached $1.75 trillion (equivalent to $174.4 billion in scale), while Tether's recently disclosed reserve size, although slightly higher than circulation, has seen its collateral ratio decrease from last year. Industry insiders point out that the decline in collateral ratio raises questions about Tether's ability to accommodate large-scale redemptions under extreme stress.
Although USDT still maintains full coverage, the market believes that marginal changes in the collateral ratio could be amplified during risk events, particularly when the crypto market experiences severe volatility and the risk of financial runs increases.
Changes in Reserve Structure Become Major Concern
Compared to the collateral ratio, S&P places particular emphasis on changes in the reserve asset structure. The report indicates that Tether has reduced the proportion of some low-risk assets while increasing the weighting of higher volatility and less transparent categories, raising concerns among regulatory and rating bodies.
Currently, about two-thirds of its reserves are still composed of short-term U.S. Treasury securities, but the remaining portion includes reverse repurchase agreements, digital assets, and asset categories of undisclosed nature. Among them, the percentage categorized as "other assets" has significantly increased over the past year, covering Bitcoin, corporate bonds, precious metals, and more complex loan-type assets.
Financial stability experts suggest that while these assets may offer higher returns, they possess weaker liquidity and more significant value fluctuations, which, in the event of a severe market downturn, could affect USDT's redemption capability and peg performance.
Industry Calls for Increased Transparency, Stablecoin Regulations May Tighten
Following the downgrade, the market calls for Tether to further enhance details of its reserve disclosure, including asset pricing sources, risk exposure disclosures, and liquidity arrangements. Some institutions point out that stablecoin issuers may face stricter capital and liquidity requirements if they assume roles akin to banks in the future.
With the U.S. and Europe promoting clearer digital asset regulatory frameworks, governance issues of stablecoins continue to be a focal point of policy discussions. Analysts expect that this rating event may prompt regulatory bodies to intervene sooner in examining the asset security and redemption rules of stablecoins.
Stablecoin Confidence Enters New Examining Phase
As the most crucial liquidity vehicle in the crypto ecosystem, USDT's future performance will hinge not only on adjustments in asset structure but also on whether Tether can achieve breakthroughs in transparency and compliance. With S&P's rating falling to the lowest tier, confidence in stablecoins is facing a new round of pressure, and how Tether responds to inquiries will become a focal point in the global crypto asset arena.
