Tether posted a net operating profit of $1.5 billion for the second quarter, driven primarily by interest income from its US Treasury portfolio and repurchase agreements, according to the company’s latest quarterly attestation released on Friday.
The money that generated it belongs, in economic terms, to the people holding USDT. They receive none of the return on it.
Reserve buffer climbs to $4.11 billion
As of 30 June, Tether’s total assets exceeded its liabilities by $4.11 billion. That surplus is the cushion standing between any loss on the reserve portfolio and the token’s dollar peg.
Set against $184.6 billion in circulating USDT, the buffer is roughly 2.2% of liabilities. Whether that is comfortable depends on what the reserves hold. For a book concentrated in short-term US government securities, which are among the safest assets available, it is a reasonable margin. It is a thinner one than most regulated banks are required to hold against their liabilities, and it leaves limited room if any portion of the reserves proved harder to sell quickly than expected.
What an attestation is, and is not
The figures come from an attestation rather than an audit, and the distinction is the longest-running question about Tether.
An attestation is a report in which an accounting firm confirms that figures provided by a company match its records at a specific moment. A full audit examines a company’s finances over a period, tests the underlying transactions and the controls around them, and delivers an opinion on whether the accounts give a true and fair view. The first is a snapshot the company assembles. The second is an independent examination.
Tether has published quarterly attestations for years while repeatedly saying a full audit is coming, and none has been produced. The reserves may well be exactly as described. The point is that the strongest available evidence for a token underpinning $184.6 billion of value, and a large share of crypto trading worldwide, remains a quarterly snapshot rather than an audit.
USDT supply rises despite stablecoin market contraction
The circulating supply of USDT increased by $446 million during the quarter, reaching $184.6 billion by the end of June. On that base, the increase is about 0.24%, which is close to unchanged.
The growth came against a broader contraction in the overall stablecoin market, valued at roughly $307 billion as of Friday according to DeFiLlama, and Tether held more than 60% of the global stablecoin market through the quarter.
Holding a flat supply while the market around it shrinks is a genuine sign of durability, and it is not the same as growth. Stablecoin supply is one of the clearer measures of how much capital is sitting ready to trade, so a contracting market means less money waiting on the sidelines. That fits what the exchanges reported this week, with industry-wide spot volume down 25% in the quarter and crypto trading revenue falling at both Coinbase and Robinhood.
Treasury exposure underpins the profit model
The earnings structure is simple. Users hand Tether dollars and receive USDT. Tether holds those dollars in Treasury bills and repurchase agreements, collects the interest, and pays USDT holders nothing. The spread between what the reserves earn and what holders receive, multiplied across $184.6 billion, produces results like this quarter’s.
Tether remains one of the world’s largest holders of US Treasury securities, and elevated short-term interest rates have amplified returns from Treasury bills, making the reserve portfolio an outsized profit engine.
That is also the model’s exposure. Almost all of this revenue is interest income, so it moves with short-term rates rather than with anything Tether does. Rate cuts are among the catalysts markets are currently pricing for, and a lower rate environment would reduce this income directly, with no change in Tether’s business, its user base or its market share.
The arrangement is legal, disclosed and standard across the industry, and competitors including Circle operate the same way. It is worth understanding plainly all the same, because it explains why stablecoin issuers have been among crypto’s most profitable companies through a period when almost nothing else has been.
The results underscore how Tether now functions less as pure crypto infrastructure and more as a yield-generating financial vehicle backed by sovereign debt, at a time when high interest rates have made that strategy unusually lucrative. For USDT holders the practical read is unchanged. The token is designed to be worth a dollar, and a strong quarter at the issuer does not make it worth more. What a profitable, well-reserved issuer does provide is a larger buffer behind the peg, which is the thing that actually matters to anyone holding it.
