Overview
- Tether’s dollar-pegged token was downgraded on Nov. 26 to 5 (weak) from 4 (constrained) on S&P’s five-point stablecoin scale.
- Bitcoin now makes up roughly 5.6% of backing, above a 3.9% overcollateralization margin S&P cites, creating a specific undercollateralization risk in a selloff.
- Tether disclosures show 75–77% of reserves in U.S. Treasuries and cash-like assets, with higher‑risk holdings around 24% as of Sept. 30, including about 8% secured loans.
- Tether rejected the assessment, highlighting large Treasury exposure, strong profitability and a record of meeting redemptions while maintaining USDT’s peg.
- The downgrade does not mandate reserve changes but is expected to intensify pressure for full independent audits and could draw increased regulatory scrutiny as USDT remains the largest stablecoin (~$180–185 billion).
