Tether (USDT) at a glance: 7.05/10 in July 2026
Tether (USDT) is a stablecoin issued by Tether Ltd, pegged to the US dollar via fiat + treasuries + secured loans. On our six-criterion composite for stablecoins, it ranks below USD Coin (USDC) and USDS (Sky) while sitting above Ethena USDe and First Digital USD in our current composite.
Stablecoin scoring weights collateral quality, transparency, and depeg history heavily — combined they represent 55% of the composite. For any stablecoin holding meaningful capital, these are the questions that determine tail risk.
Transparency and audit posture
Attestations (not full audits) published quarterly by BDO. Reserve composition disclosed at high level. Not audited by a Big Four firm. History of vague reserve claims until 2019 NYAG settlement forced better disclosure.
Transparency is the single strongest predictor of stablecoin trust. Public quarterly audits by Big Four accounting firms (or better, full SEC filings from publicly-listed issuers) rank highest. Attestations are lower-tier but still meaningful. Opaque or infrequent disclosure is a persistent risk flag.
Regulatory posture
El Salvador-registered. No US federal registration. Multiple regulatory actions historically (NYAG settlement 2019, CFTC settlement 2021). Not compliant with EU MiCA — European exchanges have delisted USDT for EU users.
Regulatory registration matters both for user access (can you legally hold this stablecoin in your jurisdiction?) and for issuer resilience (can the issuer survive a hostile regulatory action?). MiCA compliance is the current baseline for EU access; NYDFS oversight is the strongest US signal.
Collateral quality
Reserves majority in US Treasuries per attestations. Some exposure to secured loans and Bitcoin (~7% reserves 2024). Higher risk profile than pure Treasury-backed stablecoins.
Collateral composition determines what happens if the issuer needs to redeem all stablecoins at once. Pure cash + short-duration US Treasuries is highest-quality — instantly liquid, minimal duration risk. Commercial paper, secured loans, or crypto-backed collateral carry additional risk that only matters until it does.
Peg stability history
Occasional brief depegs (2018 to $0.85 briefly, May 2022 to $0.95 during Terra collapse) but always recovered. No sustained failure.
Depeg events are the most-visible stablecoin failure mode. A stablecoin that has held peg through multiple stress events (Terra collapse 2022, SVB crisis 2023) has meaningfully demonstrated its design vs one that has not been stress-tested.
Supply scale and adoption
Circulating supply of $184.15B — top-tier stablecoin by adoption. Widely accepted across CEXs and DeFi. Top-3 stablecoin by supply — used as base currency across virtually every CEX and DEX.
Larger supply usually correlates with better acceptance across trading venues and DeFi protocols. But it also concentrates issuer risk — a failure of a top-3 stablecoin would create systemic pressure across all of crypto.
Who Tether (USDT) is for — and who should look elsewhere
Best fit: High-liquidity trading on non-US venues where regulatory posture is less important than accepted-pair depth.
Look elsewhere if: Tether (USDT) is less suitable for users whose primary priority is transparency or regulation.
Direct alternatives worth comparing: USD Coin (USDC) and USDS (Sky) score higher on our composite. See Best Stablecoins.
