[!info] TL;DR Tether International’s public disclosures state that it holds reserve assets above its USD₮ token liabilities and invests most reserves in highly liquid assets such as short-term US Treasuries and repos. It reported more than $10 billion of net profit for FY2025 and $1.04 billion for Q1 2026. Profit and proprietary investments should not be conflated with the reserves backing outstanding tokens. The public materials do not substantiate the staffing or customer-level profitability figures previously stated here.

Conclusion

The following figures are based on Tether’s FY2025 disclosure and its Q1 disclosure as of 31 March 2026. A quarterly attestation provides assurance over management assertions at a point in time; it is not equivalent to a full-year financial-statement audit. ^[https://tether.io/news/tether-delivers-10b-profits-in-2025-6-3b-in-excess-reserves-and-record-141-billion-exposure-in-u-s-treasury-holdings/; https://tether.io/news/tether-posts-1-04b-q1-2026-profit-despite-highly-volatile-global-markets-reaches-all-time-highs-8-23b-reserve-buffer-and-maintains-u-s-treasury-heavy-backing/]

Reasoning

• Reserve duration, liquidity, counterparties, and prevailing interest rates affect both profitability and redemption resilience. Interest income could shrink when short-term rates decline.
• The more-than-$10-billion FY2025 figure and the $1.04-billion Q1 2026 figure cover different periods. A fixed yen conversion would vary with exchange rates and is therefore omitted.
• USD₮ can be transferred broadly on supported networks, while a direct issuance or redemption relationship with Tether is subject to identity, eligibility, and minimum-transaction requirements. It is therefore inaccurate to describe the system categorically as having no KYC or as unusable by institutions.
• Tether publishes quarterly assurance reports and announced in March 2026 that it had engaged a Big Four firm to pursue its first full financial-statement audit. The scope of an attestation and an audit must remain distinct.

Applicable When

• When discussing stablecoin economics (yen-denominated SC issuance design / commercial settlement design, see Reserve Interlock Flywheel · BUIDL ↔ USDC Systemic Circular Dependency)
• The “is a yen SC profitable?” discussion → all else equal, lower Japanese-yen short-term rates reduce gross interest income available from reserve assets. Final viability also depends on issuance outstanding, fees, operating and compliance costs, liquidity management, and credit and market risks; low rates alone do not determine whether the model is viable
• Discussion of the design of where user funds are invested → a bank-issued deposit-token structure may rest on deposit liabilities and the bank’s asset deployment, but that structure is not common to every legal type of stablecoin. For trust and funds-transfer types, verify the issuer, safeguarding method, and redemption claim separately
• When analysing a proposal to integrate USDT → assess issuance and redemption terms, reserve assets, jurisdiction, counterparties, sanctions, and AML controls separately
