Credit ratings agency S&P Global and banking giant HSBC have issued renewed warnings about the stability of Tether’s USDT. The reports highlight potential vulnerabilities in the company’s reserve structure and revive long-standing concerns about the risk of a temporary loss of the token’s dollar peg. As the world’s largest stablecoin, any instability in USDT could have wide-ranging consequences for global crypto markets.
What Happened
S&P Global Ratings recently downgraded its assessment of the reserves backing Tether USDT, stating that the composition of the company’s assets is weaker than previously believed. The agency said Tether’s reserve quality does not meet the higher standards expected for a systemically important stablecoin.
HSBC analysts Daragh Maher and Nishu Singla echoed those concerns in a new market report. They warned that the downgrade underscores persistent “de-pegging risk” — the possibility that USDT could briefly trade below or above its intended value of one U.S. dollar. Maintaining a stable peg requires highly liquid and secure reserves, making transparency and asset quality critical.
Stablecoins are designed to be redeemable at a fixed price, meaning users expect one USDT to equal one dollar at any time. This mechanism relies on the issuer holding sufficient, low-risk collateral that can quickly be accessed during periods of heavy redemptions.
Why It Matters
USDT is deeply integrated across the digital asset ecosystem. It anchors trading pairs on major exchanges, serves as a cash-equivalent for investors, and plays a central role in DeFi markets. Any erosion of confidence in Tether USDT risk could trigger liquidity shortages, wider volatility, and spillover effects across Bitcoin, altcoins, and stablecoin-reliant financial products.
S&P noted concerns about Tether’s increased exposure to riskier, less liquid investments. Such assets could make it harder for the company to meet large-scale redemptions during market stress. HSBC added that institutions subject to stricter financial rules may increasingly favor regulated stablecoins such as USDC, which is widely perceived as more transparent.
The analysts believe professional market participants may gradually shift toward fully regulated stablecoins as global frameworks tighten. However, USDT remains the dominant stablecoin by market share, and Tether continues to expand its product offerings, including a fully U.S.-compliant version currently in development.
Industry Reaction
Tether CEO Paolo Ardoino criticized the S&P downgrade, arguing that traditional rating methodologies are outdated. He pointed out that several highly rated financial institutions collapsed in the past, suggesting that legacy credit models may not translate well to the crypto industry.
Ardoino said Tether is profitable, conservatively managed, and has repeatedly demonstrated resilience during past periods of market turbulence. According to him, some traditional institutions may feel threatened by Tether’s growing influence outside conventional finance.
European Perspective
The ongoing debate comes as the EU prepares to enforce its MiCA regulatory framework, which will impose strict rules on stablecoin issuers operating within the bloc. MiCA emphasizes liquidity, transparency, and reserve quality — areas that directly intersect with concerns raised by S&P and HSBC. Analysts expect that once MiCA takes effect, institutional adoption in Europe may tilt toward stablecoins that meet these regulatory benchmarks.
What’s Next
Market observers expect increased scrutiny of stablecoin reserves as regulators worldwide introduce new compliance standards. Tether has pledged to improve transparency and continue refining its reporting practices, though some analysts remain skeptical.
For now, USDT continues to function normally, but analysts warn that monitoring reserve disclosures and regulatory developments will be crucial. Any further concerns about Tether USDT risk could influence liquidity flows across both centralized exchanges and DeFi platforms.
