- El Salvador Digital asset service provider CNAD · Jan 15, 2025
- !2017-2019: NYAG investigation found Tether-Bitfinex commingled reserves to cover an USD 850 M shortfall.
- !Reserve attestations are not full audits; no Big-Four auditor has accepted the engagement.
- !Pre-2021 marketing claimed '1:1 USD backing' that the CFTC found was inaccurate.
- !Regular OFAC freezes of large USDT addresses, especially on Tron, prompt centralization concerns.
Specific risks
- ● Concentration: Tron carries ~48% of USDT supply, exposing holders to Tron-specific tail risks.
- ● Reserve composition includes secured loans and commodity holdings — less liquid than pure Treasury portfolios.
- ● Regulatory divergence: EU access already curtailed; future US framework changes may force product splits.
- ● Single-issuer dependency — corporate failure or regulatory action could affect 60%+ of stablecoin liquidity.
