📄 What Are Reserve Reports?
Reserve reports are official documents published by stablecoin issuers to provide transparency into the assets that back their tokens. For Tether (USDT), these reports are known as the Financial Figures and Reserves Report (FFRR), prepared quarterly by the independent accounting firm BDO. They disclose the total value of reserves, the breakdown by asset class, total liabilities (USDT in circulation), and the excess reserves (assets minus liabilities).
These reports are critical for maintaining trust in the stablecoin. They allow users, regulators, and the broader market to verify that USDT is adequately collateralized and that the issuer is managing its reserves responsibly. Without such transparency, confidence in the stablecoin could erode, leading to potential de-pegging events.
Reserve reports are the primary mechanism for stablecoin issuers to demonstrate solvency. They provide the data needed to assess whether a stablecoin is truly backed 1:1, helping users make informed decisions about holding and using the token.
📊 What Is Included in a Reserve Report?
A typical Tether reserve report includes the following key sections:
- Total Reserves: The total value of all assets held in reserve.
- Liabilities: The total amount of USDT tokens in circulation (the liability Tether owes to token holders).
- Excess Reserves: The difference between total reserves and liabilities, representing a buffer above the 1:1 backing.
- Asset Breakdown: A detailed breakdown of reserve composition by asset type, including:
- U.S. Treasury Bills (the largest component)
- Repurchase Agreements (reverse repos)
- Money Market Funds
- Gold (physical and allocated)
- Bitcoin (and other digital assets)
- Secured Loans
- Bank Deposits
- Other investments (corporate bonds, precious metals, etc.)
- Attestation Report: A letter from BDO confirming the accuracy of the figures and the methodology used.
| Asset Type | Percentage (June 2025) | Approximate Value |
|---|---|---|
| U.S. Treasuries | 64.15% | $122B+ |
| Repurchase Agreements | 10.47% | ~$19.9B |
| Money Market Funds | 13.91% | ~$26.5B |
| Secured Loans | 5.89% | ~$11.2B |
| Bank Deposits | 3.69% | ~$7.0B |
| Other | 1.89% | ~$3.6B |
Values are approximate based on public attestations. Actual figures may vary by quarter.
Focus on the excess reserves — if they are positive, the stablecoin is over-collateralized. Also, examine the asset quality; a high proportion of U.S. Treasuries indicates a conservative, liquid portfolio.
📅 Frequency and Timeline
Tether has committed to publishing reserve reports on a quarterly basis. The reports are typically released within a few weeks after the end of each quarter. For example:
- Q1 report: released in April/May
- Q2 report: released in July/August
- Q3 report: released in October/November
- Q4 report: released in January/February
In addition to these quarterly attestations, Tether provides daily updates on the circulating supply of USDT on its official Transparency page. While this does not give a full reserve breakdown, it allows users to track the total liabilities in real time.
Tether has also announced plans to increase transparency further by transitioning to a full audit with a Big Four accounting firm, which would provide even greater assurance.
⚖️ Attestation vs. Audit: What's the Difference?
It is important to understand the distinction between an attestation and a full audit, as this affects the level of assurance provided.
An attestation is a review of specific financial figures, providing limited assurance. It is less comprehensive than an audit and does not examine internal controls or test all transactions in depth. It is faster and less costly to produce.
A full audit is a thorough examination of financial statements and internal controls, providing a higher level of assurance. It involves detailed testing of transactions, balances, and processes. Audits are more rigorous and time-consuming.
Currently, Tether provides attestations from BDO. However, in March 2025, the company announced its intention to conduct a first full audit with a Big Four firm, signaling a move toward the highest level of transparency. This transition is expected to further strengthen confidence in USDT's backing.
Attestations are a good starting point for transparency, but full audits offer the gold standard. Tether's move toward full audits is a positive development for the stablecoin ecosystem.
📜 Historical Context and Evolution
Tether's transparency journey has evolved significantly over the years. In its early days, the company faced criticism for not providing sufficient detail about its reserves. This led to regulatory scrutiny and user concerns.
To address these issues, Tether began publishing quarterly attestations in 2021, initially with the accounting firm Moore Cayman. In 2022, Tether transitioned to BDO, a more recognized global firm, to enhance credibility. Since then, the company has consistently released quarterly reports, gradually increasing the level of detail provided.
Key milestones:
- 2021: First quarterly attestation published.
- 2022: Switched to BDO as the attestation firm.
- 2023: Began providing more granular asset breakdowns.
- 2024: Introduced excess reserves disclosure.
- 2025: Announced plans for full audit with Big Four.
The evolution reflects Tether's commitment to improving transparency and addressing market concerns, which has helped maintain USDT's position as the leading stablecoin.
🔍 How to Interpret a Reserve Report
When you read a reserve report, look for the following indicators:
- Excess Reserves: A positive number indicates the stablecoin is over-collateralized. A negative number would be a red flag.
- Asset Quality: A high percentage of U.S. Treasuries and cash equivalents is a sign of conservative, liquid management. A growing share of Bitcoin or secured loans indicates higher risk.
- Concentration Risk: Are the assets diversified across multiple counterparties and asset classes? Concentration in a single asset or issuer increases risk.
- Trend Over Time: Compare the current report with previous quarters to see if the reserve composition is becoming more or less conservative.
If you see that U.S. Treasuries have increased from 55% to 64% over a year, while secured loans have decreased, it suggests a shift toward safer assets. This is generally positive for stability.
⚠️ Risks and Criticisms
Despite the progress, Tether's reserve reports are not without criticism:
Attestations provide limited assurance compared to full audits. Some users and regulators have called for a full, independent audit to ensure the accuracy of the reported figures.
The growing proportion of higher-risk assets (Bitcoin, secured loans, corporate bonds) has raised concerns among rating agencies like S&P Global, which downgraded Tether's stability assessment in late 2025.
While the reports disclose the asset classes, they do not always provide the granular detail (e.g., specific issuers, maturities) that some stakeholders desire.
Tether has acknowledged these concerns and is actively working to address them through the planned full audit and by continuing to enhance its disclosure practices.
🏆 Best Practices for Using Reserve Reports
- Verify Regularly: Check the latest reserve report before making significant decisions involving USDT.
- Compare Over Time: Track changes in reserve composition to identify trends.
- Assess Asset Quality: Favor stablecoins with a high proportion of liquid, low-risk assets.
- Understand the Limitations: Recognize that attestations are not full audits and plan accordingly.
- Cross-Check with Other Sources: Use independent analysis and market sentiment to complement the report.
- Stay Informed: Follow Tether's announcements regarding changes to its reporting practices.
