S&P Global Downgrades USDT Stability Rating to “5"

S&P Global Ratings has downgraded the stability rating of USDT—the world’s largest stablecoin with a market capitalization of $184 billion—to “5 (weak),” the lowest rating on its five-point scale.

Tether’s Dangerous Reserves

Bitcoin, gold, secured loans, corporate bonds, and opaque investment accounts—now account for 24% of reserves, supporting $174.4 billion in USDT in circulation, up from 17% a year ago.

Bitcoin uses just 5.6% of circulating USDT, surpassing the 3.9% threshold at 103.9%—leaving a small account if BTC falls 10-15%, as happened in October’s $20 billion liquidation. Transparency issues persist: S&P flags “limited insight” into custodians, partners, and asset product quality, with BDO’s quarterly attestation of Tether lacking the same detail as Circle’s USDC audits.

While USDT remains at $1 through shocks like Terra’s 2022 decline, S&P warns that “a significant decline” in BTC or borrowed accounts could cause the coin to lose value, similar to the $0.95 limit in 2022.

What do S&P ratings mean ?

The S&P Stablecoin Stability Score analyzes a token’s ability to maintain its peg under stress conditions — assessing its reserve composition, liquidity, counterparty risk, operational governance, and regulatory oversight.

A score of 5 indicates that S&P views USDT as structurally vulnerable, with poor resilience to market stress events, and insufficient safeguards to ensure parity with the US dollar over the long term.

This does not mean that USDT is on the verge of breaking its peg. Rather, it suggests that USDT is significantly riskier than other major stablecoins and does not meet the reliability standards expected of systemically important digital dollars.

The downgrade is consistent with concerns raised regularly by regulators, auditors and financial institutions over the years — but the formal announcement by the world's most influential credit rating agency elevates the issue from a debate to a recognized financial risk.

Regulatory Timing

S&P’s downgrade comes as global regulators are rapidly moving toward stablecoin-specific legislation:

  • US: GENIUS Act sets reserve and issuance standards

  • Europe: MiCA stablecoin mechanism officially goes live

  • Asia: Japan, Singapore, and Hong Kong are accelerating the development of a licensed stablecoin framework

  • Canada: Draft budget includes national stablecoin regulation

Latin America: Several governments are exploring the integration of CBDCs and oversight of private stablecoins

In this context, S&P’s rating is more than just an opinion — it could influence how policymakers view USDT’s risk profile, especially when deciding which stablecoins should be allowed to circulate in regulated financial markets.

Insight from HCCVenture

S&P Global’s decision to downgrade USDT to 5 – the weakest possible rating – is a watershed moment for the stablecoin industry, concerns that have long been discussed in the crypto community and opens the door for institutional capital to shift to more transparent and regulated alternatives.

USDT will remain dominant in the short term thanks to its strong network effects, global liquidity, and widespread adoption in emerging markets. However, this downgrade is a clear warning: in the next era of the digital dollar, legal legitimacy and transparency of reserves may become more valuable than market share.
