Stablecoin Reserve Reports Compared: USDT, USDC, and Others

By Chanuka Geekiyanage Oct 14, 2026

A stablecoin reserve report tells you what stands behind a token on one date, but it rarely tells you how much risk you are carrying. USDT, USDC, USDS, USDe, and PYUSD all publish something, yet the reporter, the cadence, and the asset mix differ sharply. Tether's June 30, 2026 attestation showed excess reserves of $4.11 billion, half the prior quarter, while USDC's July 2026 examination showed a reserve built almost entirely from Treasury repo and bank cash, and this article compares what each report discloses, where it stops, and which issuer's evidence deserves the most trust before you deposit.

What a Stablecoin Reserve Report Can and Cannot Tell You

Most reports are attestations, not audits. An accountant checks management's claim on a single date, and does not test whether the assets can be sold at par during a panic.

That gap matters. USDC lost its peg in March 2023 even though its reserves had been attested the month before, because part of the cash sat at Silicon Valley Bank. The reserves existed, but they were briefly out of reach.

Before you trust any report, check these six things:

Who prepared it. A Big Four firm, a mid-tier firm, or the issuer itself.
How old the data is. A report dated 60 days ago says little about today's supply.
Asset liquidity. Cash, T-bills, and overnight repo redeem at par. Loans, gold and bitcoin do not.
Counterparties. Which banks, repo counterparties, custodians, or exchanges hold the assets.
Excess reserves. Whether the report shows a buffer above liabilities or only says reserves are at least equal.
Legal claim. Whether reserves are segregated for holders if the issuer fails.

Stablecoin Reserve Reports Compared

The table below sets the five main options side by side, using the latest data points I could verify as of October 14, 2026.

Token	Reporter and cadence	What backs it	Biggest gap
USDT	BDO, quarterly attestation	About 75% cash, equivalents, and short-term deposits; gold, bitcoin, and secured loans fill most of the rest (Jun 30, 2026)	Non-cash assets, 90-day reporting gap, Big Four audit still in progress
USDC	Deloitte, monthly examination	Circle Reserve Fund (about 84%) plus bank cash (about 16%) (Jul 31, 2026)	Bank and repo counterparties; no excess reserve disclosed
USDS and DAI	No issuer attestor; on-chain data and governance forum reports	Overcollateralized crypto, stablecoins and tokenized real-world assets	Shared backing, governance control, other issuers' stablecoins as collateral
USDe	Weekly third-party proof of reserves; monthly custodian attestations	Collateral hedged with short perpetual futures	Exchange, custodian and funding-rate risk
PYUSD	Paxos monthly report plus KPMG monthly attestation	Treasuries and cash equivalents	Self-reported report is not reviewed; attestations lag

Tether (USDT)

Tether's Q2 2026 attestation, prepared by BDO and released July 31, put total assets at $187.75 billion against $183.64 billion of liabilities on June 30. That leaves a $4.11 billion buffer, down from $8.23 billion at the end of March, according to press coverage. By composition, 74.91% of assets were cash, equivalents and short-term deposits, 10.03% gold, 3.09% bitcoin and 7.17% secured loans.

The strength is liquidity. About $184.6 billion of USDT was in issuance, up roughly $446 million in the quarter while the wider market shrank, and Tether cut secured lending by $2.38 billion. The weakness is cadence and asset quality: reports arrive quarterly, and Tether itself says the Big Four audit process is continuing, so no completed audit exists.

Look at the gold, bitcoin, and secured loan lines first, because those are the assets that move or are hard to sell quickly.

Circle (USDC)

Deloitte's July 2026 examination reported USDC reserves of $71.90 billion as of July 31. Of that, $60.72 billion sat in the Circle Reserve Fund, a BlackRock-managed government money market fund holding $52.72 billion of repo and $7.18 billion of Treasuries, and $11.19 billion sat in segregated bank accounts. Circulation was about $74.3 billion on September 7, so do not compare it to the July reserve figure, because the dates differ.

USDC wins on cadence, auditor tier, and disclosure depth. Circle also publishes fund holdings daily through BlackRock and, as a listed company, files SEC reports. The trade-offs are counterparty exposure, since roughly 73% of the reserve is overnight repo and about 16% is bank cash, and the lack of a stated excess buffer.

How these reserve differences play out inside lending pools and DEX liquidity is covered in our breakdown of USDC vs USDT vs DAI in DeFi.

Compare the Circle Reserve Fund share against the bank cash share, because the bank portion is where the 2023 failure happened.

Sky (USDS and DAI)

DAI and USDS convert one-to-one and share a single backing, so you cannot tell what backs one versus the other. There is no Big Four attestation. Real-world asset collateral is reported vault by vault on the Sky governance forum, such as the RWA Foundation and HVB monthly cash report for July 2026, and on-chain data is tracked on DeFiLlama and daistats.

The key risk is circular exposure. Some collateral is itself another issuer's stablecoin, so a USDC problem can become a USDS problem. Sky is a good fit if you value on-chain verification and accept governance and shared-backing risk.

Ethena (USDe)

USDe is not a reserve story in the usual sense. Ethena holds collateral and opens short perpetual futures against it so the position stays dollar-neutral. It publishes a transparency dashboard, third-party proof of reserves that is typically weekly, and monthly custodian attestations.

USDe briefly traded near $0.97 during the October 10, 2025 market crash, and supply was about $5.92 billion by March 2026. No report removes exchange failure, custodian failure, or negative funding rates. Treat USDe as a yield position, not as cash.

PayPal USD (PYUSD)

Paxos publishes two documents each month. One is a self-reported reserve composition that has not been independently reviewed, and the other is a KPMG attestation for reports on or after February 28, 2025. On August 18, 2026, the public index listed attestations through June, so the lag can run several weeks.

The reserve is narrow and conservative, which is a plus. The supply was only about $2.7 to $2.9 billion in mid-2026, so liquidity is thin outside PayPal's own rails.

How Much Cushion Does Tether Really Have?

Gold and bitcoin together were about $24.6 billion, or 13.1% of assets, on June 30. The $4.11 billion buffer equals roughly 17% of that amount. By my arithmetic, a fall of that size in both assets, with nothing else changing, would erase the buffer.

Do not read that as insolvency. About three quarters of reserves are liquid, and Tether attributes the quarter's strain to sharp swings in gold and bitcoin, not to redemptions. The practical point is that the buffer can move by billions in one quarter, and you only learn about it weeks after the quarter ends.

Tether also holds more than 60% of the stablecoin market by its own figures, so the market data matters as much as the report.

Where US Regulation Changes the Picture

The GENIUS Act, signed July 18, 2025, requires licensed issuers to publish monthly reserve composition examined by a registered public accounting firm, with CEO and CFO certifications. Issuers with more than $50 billion outstanding also need annual audited financial statements, and only USDT and USDC exceed that line today.

The effective date is January 18, 2027, or 120 days after final rules if that comes first, and regulators missed a July 2026 target for finalizing them. Treasury's August 18, 2026 proposal on foreign issuers, with comments due October 19, is the one to watch for Tether, since how it applies to a non-US issuer depends on those rules.

Which Stablecoin Fits Which Situation

Situation	Recommended option	Why
Large balance you may need to redeem quickly	USDC	Monthly Big Four examination, Treasury repo and cash, segregated reserve
Trading where USDT has the deepest liquidity	USDT, sized small	Best market depth, but quarterly reporting and non-cash assets call for a cap.
DeFi user who wants on-chain verification	USDS or DAI	Collateral is visible onchain; accept governance and shared-backing risk
Chasing yield	USDe or sUSDe, as a risk position	Synthetic backing and exchange exposure make it unsuitable as a cash balance
Payments inside the PayPal ecosystem	PYUSD	Narrow reserve, but small supply and delayed attestations

If you hold more than one of these, keep the split deliberate. The framework in stablecoin allocation across protocols and diversification helps you size each position against its risk.

Common Mistakes When Reading Reserve Reports

Treating an attestation as an audit. It confirms a claim on one date, not ongoing solvency.
Ignoring report age. Quarterly data can be nearly 90 days old before the next one lands.
Reading the headline ratio only. Reserves above 100% mean little if the excess sits in gold, bitcoin, or loans.
Comparing different dates. Setting July reserves against September supply produces false gaps.
Overlooking counterparties. Bank cash, repo desks, custodians and exchanges are where failures start.
Assuming decentralized means safer. Shared backing and governance control are real risks.

My Take

For core holdings, I would pick USDC. The monthly Big Four examination, the Treasury repo and cash mix, and the fund-level daily disclosure give the strongest evidence of the five. Its weak spots are bank and repo counterparties, so I would still spread cash across more than one bank-exposed stablecoin or fiat on-ramp.

I would hold USDT only where its liquidity is needed, and size it to what I could tolerate losing a few percentage points on. The quarterly cadence and the 13% gold and bitcoin sleeve are enough to cap it. I would use USDS or DAI if I wanted on-chain-verifiable collateral and could monitor governance, and I would treat USDe strictly as a yield bet.

Before depositing, I would check four things: the date of the latest report against current supply, the share of non-cash assets, who holds the cash, and whether redemption is available to me directly. If a stablecoin fails any of those, I would move to another option.

Conclusion

The best-supported choice for large balances is USDC, thanks to monthly Big Four examinations and a reserve made of repo, Treasuries, and bank cash. USDT remains the liquidity leader, but a halved buffer, a quarterly cadence, and about 13% of assets in gold and bitcoin justify position limits. USDS, DAI, and USDe offer on-chain transparency, but they carry governance, collateral, and exchange risks that reports cannot remove.

Your next step is simple. Open the latest report for each stablecoin you hold, confirm the date and the asset mix, and cap any position you cannot verify. This is analysis, not financial advice, and every figure here will change with the next report.

FAQs

1. Is USDT safe to hold after Tether's reserve buffer fell by half?

The June 30, 2026 attestation still showed assets above liabilities by $4.11 billion, and about 75% of reserves sit in cash, equivalents, and short-term deposits. The buffer is thin against roughly $24.6 billion of gold and bitcoin, so cap your exposure instead of treating USDT as cash.

2. Is a monthly attestation better than a quarterly one?

Yes, for freshness, because a 30-day-old snapshot says more about today than a 90-day-old one. It is still a point-in-time check, so asset quality matters as much as frequency.

3. Why did USDC lose its peg in 2023 if its reserves were attested?

Part of Circle's cash sat at Silicon Valley Bank when it failed, so the reserves existed but were briefly out of reach. That is why you should read where the cash is held, not just the total.

4. Are DAI and USDS safer than USDT or USDC?

They are more transparent on-chain, but not safer by default, since the backing is shared, includes real-world assets, and depends on governance decisions. Treat them as a different risk profile, not a lower one.

5. How often should I check a stablecoin reserve report?

Check the latest report whenever you add a large deposit, and at least monthly for any DeFi position. Always compare the report date with current supply, because a report cannot reflect changes after its reporting date.
