Tether's reserve buffer halved in Q2 while the company led with a $1.5 billion 'operating' profit

Tether published its second-quarter reserve report on Friday, and the number it put at the top — $1.5 billion in net operating profit — is not the number that moved.

The number that moved is the buffer. According to the BDO attestation covered by CoinDesk, the USDT issuer held $187.75 billion in assets against $183.64 billion in liabilities as of June 30, leaving $4.11 billion in excess reserves. Three months earlier that figure was just over $8.23 billion. The Block, working from the same disclosure, put the quarter-on-quarter decline at $4.1 billion and described the buffer as "cut in half." Both outlets agree on the direction and roughly on the size; the halving is the story.

Run the ratio and the compression is clearer than the dollar figure suggests. On the reported June 30 numbers, the cushion covers about 2.2% of liabilities. At the end of Q1, on the figures both outlets cite, it covered roughly 4.5%. Tether is still over-collateralised on its own disclosure — but by half as much as it was in March.

Where the buffer went

Two of Tether's three headline reserve assets are marked to market, and both marks moved against it.

Gold: Tether added 14 metric tons during the quarter, lifting physical holdings from 132.2 tons to roughly 146.2 tons, CoinDesk reported. The value of that larger pile fell, from $19.84 billion to $18.84 billion, because the gold price dropped to just over $4,000 an ounce — a decline CoinDesk characterised as about 15%. The Block, less precisely, said gold and bitcoin each shed more than 10% in the quarter. The implied per-ounce marks in the report itself work out to roughly $4,670 at the end of Q1 and roughly $4,010 at the end of Q2, a fall closer to 14%.

Bitcoin: holdings rose by about 1,796 coins to 98,933 BTC, per CoinDesk, while the mark used in the report fell from $68,200 to $58,600 — also about 14%. Value dropped from $6.62 billion to $5.80 billion. As The Block noted, Tether marks its bitcoin to market the way Strategy does, so price declines flow straight into reported value.

Add the two together and the mark-to-market damage is roughly $3.7 billion before the roughly $1.9 billion of gold and bitcoin Tether bought during the quarter. Set that against $1.5 billion of operating profit and you get somewhere near a $2.2 billion negative quarter.

That is not what the company reported. The Block flagged a negative $3.2 billion financial result for the first half of 2026 and, netting out the $1 billion net profit Tether reported for Q1, calculated an implied Q2 loss of more than $4 billion. The Block wrote that Tether did not disclose what drove the remainder of the negative result and did not immediately respond to a request for clarification. On the arithmetic above, the unexplained portion is on the order of $2 billion — and it is the single largest open question in the disclosure.

One partial thread: The Block reported that Tether's secured-lending exposure fell by $2.4 billion during the quarter. Whether that reflects loans repaid, positions unwound, or something written down is not stated in the disclosure.

The metric that changed

Last year Tether reported $4.9 billion in net profit for Q2 2025. This year it emphasised $1.5 billion in net operating profit — a measure that, as The Block explained, generally excludes unrealised gains and losses on assets like bitcoin and gold. That exclusion is doing a great deal of work in a quarter when both assets fell about 14%.

The $1.5 billion itself is real and comes from a boring, durable place: CoinDesk attributed it to returns on Tether's U.S. Treasury and repurchase-agreement holdings. That is the franchise. The volatility sits in the roughly $24.6 billion of gold and bitcoin bolted onto it.

USDT supply, meanwhile, grew modestly. CoinDesk reported issuance rose about $446 million to $184.6 billion in the quarter — under 0.25% growth. Decrypt's coverage led on the same combination: $1.5 billion profit, supply growth, higher gold holdings.

Key facts

• Excess reserves at June 30: $4.11 billion, from $8.23 billion at March 31 — a $4.1 billion decline (BDO attestation via CoinDesk; The Block)
• Assets vs liabilities: $187.75 billion against $183.64 billion (BDO attestation via CoinDesk)
• Gold: 146.2 tons, up 14 tons; value $18.84 billion, down from $19.84 billion (CoinDesk)
• Bitcoin: 98,933 BTC, up ~1,796; value $5.80 billion, down from $6.62 billion; marks moved $68,200 → $58,600 (CoinDesk)
• USDT outstanding: $184.6 billion, up ~$446 million in the quarter (CoinDesk)
• First-half 2026 financial result: negative $3.2 billion; implied Q2 loss of more than $4 billion after Q1's $1 billion profit (The Block's calculation)
• Secured lending exposure: down $2.4 billion in the quarter (The Block)
• Year-ago comparison: $4.9 billion net profit in Q2 2025 (The Block)

The real-world read

The headline metric was swapped mid-race. A company that reported "net profit" of $4.9 billion in a good quarter reported "net operating profit" of $1.5 billion in a bad one. The Block called this out directly, and the choice is not neutral: the excluded line items are precisely the ones that went wrong. Any year-on-year comparison of $4.9 billion to $1.5 billion is apples to oranges, and readers should treat it that way in both directions.

"A great second quarter." CEO Paolo Ardoino's characterisation on social media, quoted by The Block — "Tether had a great second quarter of 2026 ... despite highly volatile global markets" — describes a period in which the company's own filing shows a negative first-half result and a halved reserve cushion. That is the company's framing of the company's numbers, and it should be discounted accordingly.

Roughly $2 billion is unaccounted for. Mark-to-market losses on gold and bitcoin explain about $3.7 billion. The implied Q2 loss is over $4 billion, against $1.5 billion of operating income. The Block said Tether did not disclose the rest and did not respond to its request for clarification. Absent an explanation, that gap is the most important unknown here.

The user number is unaudited and undefined. Ardoino's claim of an all-time high of more than 650 million USDT users, per The Block, comes from the company, with no stated methodology. Wallet counts are not people. Treat it as marketing until it is defined.

An attestation is not an audit. What BDO produced is a point-in-time verification of reported balances, not a full financial-statement audit with an opinion on the entity as a whole. That distinction matters more, not less, when a quarter's results hinge on undisclosed items.

A figure that does not line up. Liabilities are reported at $183.64 billion while USDT outstanding is given as $184.6 billion — a gap of roughly $1 billion in the same disclosure, as relayed by CoinDesk. There may be a mundane reconciliation. It isn't spelled out.

Left unsaid. The report gives no explanation of the secured-lending decline, no breakdown of what else hit the P&L, and no statement on whether any capital was distributed to the parent — a factor that would also reduce excess reserves without being a loss at all.

Opinion, and whose

• Paolo Ardoino, Tether CEO (via social media, quoted by The Block): the quarter was "great ... despite highly volatile global markets," and the USDT user base reached an all-time high above 650 million. This is the issuer's assessment of its own results, and the user figure is self-reported.
• The Block's reading (reporter RT Watson): the results represent "a sharp year-on-year deterioration," with an implied Q2 loss above $4 billion derived from the reported half-year figure. That derivation is the outlet's arithmetic, not a company disclosure.
• CoinDesk's framing: the story is a reserve buffer that "falls by half" alongside continued accumulation of gold and bitcoin.

None of the above is a forecast of what Tether or USDT does next, and no one quoted here offered one.

For context on where the marks sit now rather than at quarter-end: Decrypt's price data on July 31 showed bitcoin around $62,887 — above the $58,600 used in the June 30 report — and gold-backed tokens XAUT and PAXG quoted near $4,040. Marks taken on a single date are snapshots, and Q3's will be a different snapshot.
