Tether's safety has been a recurring debate since 2018. By 2026, the reserve quality has improved dramatically — but transparency remains imperfect. Here's where things actually stand.
Reserve composition
Per Tether's quarterly attestations (BDO, since 2022), reserves are now ~85% US Treasury bills (short-term, T-bills + reverse repos), ~5% cash equivalents, and the remaining ~10% in lending, secured loans, BTC, gold, and 'other'.
This is a major improvement from 2019 when commercial paper made up 40-50% of reserves.
Attestations vs audits
BDO publishes attestations — point-in-time confirmations that reserves exceed liabilities. Tether has never published a full financial audit.
Attestations have known limitations: they're snapshots, they don't verify accounting controls, and they don't cover ongoing operations between dates.
Tail risk
Tether is reportedly profitable from T-bill yields (~$5-7B/year in 2024-25). Their balance sheet capacity is significant.
Tail scenarios: large redemption pressure (potentially during a broader crypto sell-off) could test the cash-equivalents fraction. Reserves outside cash and T-bills are less liquid in stress.
For Indian P2P traders holding USDT for hours/days at a time, tail risk is essentially zero. For long-term holders of large amounts, it's a real consideration.
Key takeaways
- Reserves: ~85% US T-bills, ~5% cash, ~10% other.
- Attestations are good; full audits would be better and don't exist.
- Tail risk reduced significantly since 2019; isn't zero.
- Short-term holding (hours/days): negligible risk. Long-term large holding: meaningful but small.
