Tether USD (USDT) Review

Is USDT safe? The short answer

Is USDT safe? For the reserves, mostly yes: Tether's latest attested report shows $187.75 billion of assets against $183.64 billion of liabilities at 30 June 2026. The weaker points are elsewhere. About a quarter of those assets are gold, bitcoin, secured loans, equities and other investments, most holders cannot redeem with Tether directly, Tether can freeze any address, and US and EU rules increasingly decide where you can buy and hold it.

That split matters because the question means different things to different readers. A trader parking funds between positions for a few hours cares about the peg and exchange liquidity, where USDT has no equal. Someone holding savings in USDT for a year carries reserve risk and legal risk too. And a freelancer paid in USDT on Tron mostly needs to know how to get dollars into a bank account. This page takes each risk in turn, with a dated source for every number.

What is USDT, and who issues it?

USDT, or Tether USD, is a token that is meant to be worth one US dollar and that Tether promises to redeem at face value for verified customers. It launched in 2014 and is the largest stablecoin by a wide margin.

On 15 October 2026 Tether's transparency feed showed 183.66 billion USDT in circulation, and CoinGecko put its market value at $183.49 billion on 16 October, ranking it third among all crypto assets and a little below its spring 2026 peak of about $190 billion. DefiLlama counts that as 60.0% of all dollar-pegged stablecoin supply.

The issuer is Tether International, S.A. de C.V., a company incorporated in El Salvador with its registered office in San Salvador. Tether announced the move of its group headquarters to El Salvador in January 2025, and the country's digital-asset regulator, the CNAD, lists Tether International as a registered stablecoin issuer (EME-0003, dated 19 May 2025) and as a digital asset service provider (PSAD-0028).

Before the move, most group companies were incorporated in the British Virgin Islands, CoinDesk reported. Paolo Ardoino is chief executive and Giancarlo Devasini chairs the company, according to Tether's own about page.

Tether makes money on the gap between what its reserves earn and the zero it pays holders. USDT pays no interest. Any "USDT yield" you see on an exchange or a lending app is paid by that platform, which adds its own risk on top of Tether's.

What backs USDT right now?

USDT is backed mostly by short-dated US Treasury bills and repo, plus a sleeve of riskier assets. The figures below come from the Q2 2026 reserve report, which BDO's Milan practice signed on 31 July 2026 for the position at 30 June 2026.

Why did the reserve cushion halve?

Two things changed since the spring.

First, the cushion halved. The Q1 report showed $8.23 billion of excess reserves at 31 March 2026; by 30 June it was $4.11 billion. The report values bitcoin at $58,642 against $68,194 three months earlier, and its equity table shows a first-half financial result of minus $3.17 billion.

Tether's press release for the same quarter headlines a $1.5 billion net operating profit instead. Both can be true at once if the "net operating profit" figure leaves out the fall of about 14% in gold and bitcoin prices during the quarter, but Tether does not define that metric, BDO does not assure it, and the release does not reconcile the two.

Part of the reason the cushion is thin is that Tether paid out more than it earned in 2025. The year-end 2025 report shows a 2025 financial result of $10.11 billion and $10.86 billion of dividend distributions, so equity fell over the year.

Second, the risk sleeve is now the number to watch. Gold, bitcoin, secured loans, equities and other investments add up to about $47 billion, or roughly 25% of assets. Bitcoin alone equals 3.2% of liabilities, which is more than the 2.2% excess. If bitcoin fell far enough while everything else held still, the excess would be gone on paper.

That is the core of S&P Global's concern: in November 2025 it cut USDT to 5 ("weak"), the bottom of its stablecoin stability scale, citing bitcoin exposure above the overcollateralisation margin and limited disclosure on custodians and counterparties, as CoinDesk reported.

The next quarterly report covers 30 September 2026. Tether posted the equivalent report around 31 October last year, so expect it in late October or early November.

Is Tether audited, or only attested?

Both, since this summer. The quarterly reserve reports are attestations: BDO gives reasonable assurance under the ISAE 3000 (Revised) standard that the reserve figures were right at one moment, 23:59 UTC on the report date. An attestation does not test what happened between report dates, and the notes to the report sit outside BDO's assurance.

The bigger change came on 13 August 2026, when Tether announced that KPMG had issued an unqualified opinion on Tether International's financial statements for the year ended 31 December 2025, with reserves exceeding liabilities by $6.81 billion on the audited basis.

It is Tether's first full-year audit. KPMG has confirmed that it issued the opinion, but as of 16 October 2026 Tether had published neither the audited financial statements nor KPMG's opinion letter. The attested figure for the same date was $6.34 billion, and the two numbers rest on different accounting bases that Tether has not reconciled publicly.

History explains the scepticism. In October 2021 the CFTC fined Tether $41 million and found that, in a 26-month sample from 2016 to 2018, Tether held enough fiat to back USDT on only 27.6% of days while describing it as fully backed by dollars. Earlier that year Tether and Bitfinex paid $18.5 million to the New York Attorney General and agreed to stop trading with New Yorkers.

Today's disclosure is far better than that. It is still quarterly, not monthly, and the issuer still sits outside US bank supervision. Older claims are still in court, too: a class action accusing Tether and Bitfinex of manipulating bitcoin prices in 2017 and 2018 was certified on 6 March 2026 in New York federal court, and the Q2 report lists it as pending litigation. Certifying a class is not a finding of liability.

Has USDT ever lost its dollar peg?

Yes, several times, and the 2022 episode took about two months to settle fully. Market prices fell in each case; what differed was how long the gap lasted.

In 2022 the pattern was clear. USDT traded a few cents under a dollar, large holders redeemed with Tether at par, and the supply shrank until the price recovered. The mechanism works only if redemptions keep flowing, which is why the reserve mix in the table above matters more than any past track record.

Can Tether freeze your USDT?

Yes. Tether's terms of service, updated 26 February 2026, reserve the right to freeze tokens, blacklist any address that holds them and "seize and recover" them. Its February 2026 disclosure document adds that Tether may freeze, burn or block the transfer of tokens.

Tether uses the power often and says so. In a 28 September 2026 release the company claimed it works with more than 340 law-enforcement agencies in 70 countries and has helped freeze more than $5 billion of assets, including about $550 million in 2026 tied to Iran-linked wallets named by US authorities. Those are Tether's own figures.

For an ordinary holder this cuts both ways. Freezing helps victims of hacks and scams recover funds.

It also means a USDT balance is not bearer money. Any address Tether links to sanctions, theft or a court order can be frozen, whoever controls it.

On 5 October 2026 the payments firm Conduit sued Tether in New York over $2.76 million of USDT it says has been frozen in its treasury wallet for more than a year. Four days later Tether blacklisted four THORChain vault addresses holding about 1.45 million USDT and unfroze them hours later, Cointelegraph reported. A security review by Hacken, reported by CoinDesk in September 2026, added a different worry. It found that about $91.3 billion of USDT on Tron sits under a 2-of-3 multisig with no timelock, with the same signing keys reused on several chains. Hacken found no sign of compromise.

How do you turn USDT back into dollars?

Most people sell it on an exchange; only verified Tether customers can redeem at face value, and US persons are excluded. The fee page sets the terms for direct redemption:

• Minimum redemption: US$100,000.
• Redemption fee: the greater of US$1,000 or 0.1%.
• Account verification: US$150, paid in tokens.
• Withdrawal requests are reviewed one by one and "can take several days".
• Eligibility: KYC-verified customers only. The terms class every US person as a prohibited person, apart from eligible contract participants that Tether accepts.

Tether's February 2026 disclosure document counted 819 verified customers. Everyone else, which is almost every retail holder, exits through the market: sell USDT for dollars on an exchange that lists the pair and withdraw to a bank, or swap it for USDC first.

On 16 October 2026 the public trading APIs of Coinbase, Kraken and Binance.US all showed a live USDT/USD market. Kraken does not serve residents of New York or Maine. Robinhood lists USDT for price data only; its coin availability page shows USDC and USDG as the tradable stablecoins.

One practical warning. Exchanges support USDT on different networks. Coinbase, for example, lists USDT on Ethereum, Arbitrum, Polygon and Tempo, but not on Tron or Solana. Sending USDT over a network the receiving platform does not support can leave the funds stuck or lost, depending on its recovery policy. Check the network on both sides before you send.

Is USDT legal in the US after the GENIUS Act?

Yes, holding and trading USDT is legal in the US today, but the GENIUS Act sets dates after which US platforms will be limited in offering it. The law was signed on 18 July 2025. According to the Treasury's August 2026 proposed rule, it takes effect on the earlier of 18 January 2027 or 120 days after final regulations. Two provisions hit a foreign issuer such as Tether:

• From the effective date, a US exchange or broker may only make a foreign issuer's stablecoin available if the issuer can, and will, comply with lawful US orders, such as an order to freeze.
• From 18 July 2028, US platforms may only offer payment stablecoins from permitted issuers, unless Treasury finds the foreign issuer's home regime comparable and the issuer registers with the OCC. As of 16 October 2026 the Federal Register shows no such comparability finding for any country.

The proposed reserve rules matter too. The OCC's February 2026 proposal limits permitted issuers' reserves to cash, insured deposits, Treasuries maturing within 93 days, Treasury repo and government money funds. Gold, bitcoin, secured loans, equities and other investments are not on that list, and together they made up about a quarter of USDT's reserves at 30 June 2026. Treasury's comment period closes on 19 October 2026; the final rules are not out yet. The law also leaves self-custody wallets and person-to-person transfers outside these platform rules.

What is USAT, Tether's US coin?

Tether's answer for US users is a separate coin. USA₮ (USAT) launched on 27 January 2026, issued by Anchorage Digital Bank, N.A., a federally chartered bank, with Cantor Fitzgerald as reserve custodian and Bo Hines as chief executive of the USAT business. It is small next to USDT: DefiLlama showed about $183 million of USAT on 16 October 2026. Tether says USDT itself is "progressing towards GENIUS Act compliance"; that is the company's claim, not a regulatory finding.

New York adds its own limits. USDT is not on the NYDFS greenlist of coins that licensed firms may list without separate approval, and the 2021 settlement bars Tether and Bitfinex from trading with New Yorkers.

Why did Europe delist USDT, and where does the UK stand?

USDT has no authorisation under the EU's MiCA regulation, so EU-licensed exchanges stopped offering it for trading between December 2024 and March 2025. No Tether entity appears on ESMA's register of authorised e-money token issuers. Coinbase began restricting USDT for European users in December 2024, Kraken halted EEA spot trading on 24 March 2025, and Binance closed its EEA USDT pairs on 31 March 2025.

Until this month, EU users could at least keep USDT in custody and move it. On 8 October 2026 ESMA published an opinion telling licensed crypto firms to stop all services for non-MiCA stablecoins, including custody and transfers, and to wind down remaining exposures within three months. Tether's European route runs instead through Quantoz Payments, a Dutch e-money firm it invested in, which issues MiCA-compliant EURQ and USDQ.

The UK has not banned USDT but does not authorise it either. The FCA published its final cryptoasset rules on 30 June 2026, opened its authorisation window on 30 September 2026 and plans to start the full regime on 25 October 2027. The stablecoin issuance rules cover coins issued from the UK, and USDT is not one of them, but UK platforms that trade or hold USDT for customers will fall under the wider regime.

Which blockchains is USDT on?

Tether issues USDT natively on 13 blockchains, and two of them hold almost all of it. Tron carries 50.6% of circulating USDT and Ethereum 46.8%, by our calculation from Tether's transparency feed on 15 October 2026.

The distinctions are easy to miss. USDT0 is a wrapped version built on LayerZero, so holding it adds the bridge contract's risk to Tether's. USDT on BNB Chain is a bridged token too, even though it carries the USDT name; DefiLlama counts about $9.2 billion of it. For a native list, use Tether's supported-protocols page.

USDT vs USDC: which is safer?

On reserves and regulation, USDC is the safer coin; on liquidity and reach outside the US and EU, USDT wins clearly. The table sets the main differences side by side.

The trade-off is plain. If you need the deepest order books on offshore exchanges or transfers on Tron, which carries half of all USDT, USDT is the tool the market uses. If you are holding dollars for weeks or months, and especially if you are in the US or the EU, a coin backed only by cash and Treasuries, from a US- or EU-regulated issuer, carries less risk for the same zero yield.

How is USDT taxed in the US?

The IRS treats USDT like any other digital asset: it is property, not currency. Selling, swapping or spending it is a taxable disposal, although gains are usually tiny because the price barely moves.

The IRS digital assets page says brokers report gross proceeds on Form 1099-DA for sales from 1 January 2025 and cost basis for certain sales from 1 January 2026. For qualifying stablecoins, the 1099-DA instructions offer brokers an optional method that skips reporting for a customer whose total stablecoin sales proceeds stay at or below $10,000 for the year. That reporting relief does not remove your own duty to report gains. Our US crypto tax guide covers the forms in detail.

Who should hold USDT, and who should not?

USDT suits traders who need maximum liquidity, users in countries where it is the de facto digital dollar, and anyone receiving payments on Tron, the network that carries half of all USDT. For those uses, the reserve sleeve and the freeze power are known costs of the most liquid dollar token there is.

It suits long-term holders less. Tether keeps the interest, reports quarterly and holds a quarter of its reserves outside cash and Treasuries, in assets the proposed US rules would not let a permitted issuer hold. Its US platform access also hinges on a 2028 deadline.

If you are in the EU, the ESMA opinion makes custody harder by January 2027. If you are a US holder parking money for months, USDC or PayPal USD covers the same need with a US-supervised issuer, and our stablecoin comparison scores each coin on the same criteria. For the basics of how pegs work, start with what a stablecoin is.
