What backs USDT?
As of Tether's most recent quarterly attestations, the large majority of USDT reserves are US Treasury bills and overnight/term repo — a mix Tether has grown steadily since 2021, when commercial paper made up a meaningful share. The remainder sits in secured loans, precious metals and bitcoin, which is the part worth watching in a stress scenario.
The shift away from commercial paper
In 2021, Tether disclosed tens of billions of dollars in commercial paper — short-term corporate debt that is less liquid and carries more credit risk than government securities. Following regulatory pressure and market scrutiny, Tether reduced its commercial paper holdings to zero by 2022, replacing them almost entirely with US Treasury bills, which is where the bulk of reserves has stayed since.
What's in reserves today
Tether's attestations break reserves into Treasury bills and repo (the dominant category), cash and bank deposits, secured loans to third parties, corporate bonds and funds, precious metals (mostly gold), and bitcoin. The Treasury-heavy portion functions like a money-market fund. The secured loans and bitcoin allocations are the parts that cannot necessarily be liquidated at face value on short notice.
- US Treasury bills and repo: the dominant category, high quality and liquid
- Cash and bank deposits: held across multiple banking relationships
- Secured loans: lending collateralised by assets, the least transparent line item
- Bitcoin and gold: a meaningful allocation that adds market-price volatility to the reserve
Attestation vs audit
Tether publishes a quarterly attestation from an accounting firm confirming balances existed at a specific date. This is materially weaker assurance than a full audit, which would test internal controls and the accuracy of records across the whole period, not just a snapshot. Tether has said for years it intends to pursue a full audit; none has been completed as of the most recent reporting.
Frequently asked
- Does USDT hold commercial paper?
- No, not since 2022. Tether eliminated commercial paper from its reserves and shifted almost entirely into Treasury bills and repo.
- How much bitcoin does Tether hold in reserves?
- A minority but non-trivial allocation, disclosed in each quarterly attestation. It adds price volatility that the Treasury portion does not carry.
- Is Tether audited?
- No full audit has been published; reserves are confirmed via quarterly attestations, a lighter form of assurance than an audit.
- Who attests Tether's reserves?
- Tether has used BDO for its attestation reports in recent years, after earlier reports from other firms.
