USDT meaning: what Tether is and how it works

The meaning of USDT: it is the ticker for Tether's US dollar token, a stablecoin designed to hold a value of 1 US dollar. Its issuer writes it USD₮. It is issued on blockchains by a private company, Tether International, S.A. de C.V. It is not a US dollar, not issued by any government and not bank-insured. Tether redeems tokens at 1 dollar less fees, but only for its own verified customers. This page covers what backs USDT, which network to use, the risks, and US and UK rules as of November 2026.

What USDT means and what currency it tracks

The USDT meaning sits in the ticker: it combines "USD" for the US dollar with "T" for Tether. USDT is denominated in US dollars. Tether is the company, and USDT is its dollar token, which is why you also see it called USDT Tether.

Tether's other tokens include a gold token (XAU₮) and a Mexican peso token (MXN₮). It is winding down its offshore yuan token (CNH₮, redemptions end 20 February 2027) and has wound down its euro token EUR₮. USA₮ is also a different token from USDT, as the United States section explains.

Is USDT a cryptocurrency?

In the technical sense, yes. USDT is a token recorded on blockchains, and you move it between wallets like other crypto. Unlike bitcoin, it is designed not to change in price, and a single company issues and redeems it. The IRS lists stablecoins as an example of digital assets, and the tax rules further down explain what that means for US and UK readers.

How does USDT work?

Issuing and redeeming

Tether creates new USDT when verified customers send it dollars, and it destroys the USDT it redeems. Tether states that all its tokens are pegged 1 to 1 with a matching fiat currency and are "backed 100% by Tether's Reserves". That is the issuer's statement.

Only verified Tether customers can have tokens issued or redeemed by Tether. Redemptions have minimum amounts and other requirements, and the price is 1 dollar per token less fees where applicable. As of November 2026, Tether's fees page sets a minimum of $100,000 per acquisition or redemption, a redemption fee of the greater of $1,000 or 0.1%, and a non-refundable $150 verification fee paid in Tether tokens. Direct redemption is built for large customers. Most people swap USDT for dollars on an exchange or with another user instead, so the market price can drift slightly from 1 dollar. Our guide on how buying and selling crypto works covers those swaps in general terms.

What backs USDT as of September 2026

The table shows Tether's own figures as of 30 September 2026, from an attestation prepared by BDO and published on 30 October 2026 in Tether's Q3 2026 report release.

USDT issuance held at about $184 billion through the first three quarters of 2026. In August 2026 Tether announced that KPMG U.S. had issued an unqualified audit opinion on its 2025 financial statements, which put reserves $6.814 billion above liabilities at 31 December 2025.

Which network your USDT is on (TRC20, ERC20 and others)

USDT exists as separate tokens on many blockchains. As of November 2026 Tether lists support on Ethereum, Tron (TRC20), Solana, TON, Avalanche, Polkadot Asset Hub, Aptos, Celo, Kaia, Near, Tezos, Cosmos via Kava and Liquid. "TRC20" is the Tron version. "ERC20" is a token format rather than one network: Tether lists ERC20 USDT on Ethereum, Avalanche, Cosmos via Kava, Celo and Kaia, so the label alone does not tell you which network a platform uses. Network fees differ between chains.

An address on one network does not work on another, and sending USDT on the wrong network can lose the funds. Before you send:

• Make sure the sender and the receiver use the same network.
• Check the network label on both sides.
• Send a small test amount first.

Our guide to keeping crypto in a wallet you control explains addresses and wallets.

Wrapped or bridged versions of USDT made by third parties are not Tether tokens, and Tether will not redeem them. Tether also stopped redeeming USDT on Omni, Bitcoin Cash SLP, Kusama, EOS (now called Vaulta) and Algorand from 1 September 2025.

The difference between USD and USDT

A dollar in a US bank account is a claim on a regulated bank, and in the US it can carry deposit insurance. USDT is a token from a private company. Tether's own terms say its tokens are not legal tender, not backed by any government and not covered by FDIC or SIPC protection. Only Tether's verified customers can redeem with Tether, so everyone else relies on selling the token to someone else. For UK readers, the FCA says crypto is largely unregulated in the UK and it is highly unlikely you will be covered by the Financial Services Compensation Scheme for crypto losses.

Under the GENIUS Act, covered below, permitted US stablecoin issuers may not market their coins as legal tender, government-guaranteed or FDIC-insured. That rule concerns permitted issuers, and this page makes no claim about whether USDT is one.

What USDT is used for

People use USDT to move dollar value between exchanges and wallets without a bank transfer, to hold a dollar balance inside crypto, and to pay where a merchant accepts it. Our guide to how paying with crypto works covers the basics of paying with crypto, and the one on crypto debit cards explains how card spending from a crypto balance works.

Anyone promising a fixed return on USDT, or asking you to pay a "fee" or "tax" in USDT to release money, matches common crypto scams.

Risks: reserves, the peg and frozen access

In February 2021 the New York Attorney General reached an agreement with Tether and Bitfinex that ended their trading with New Yorkers and imposed $18.5 million in penalties. The office found that from mid-2017 Tether had no access to banking and, for periods, held no reserves at one dollar per token.

In October 2021 the CFTC ordered Tether to pay a $41 million civil penalty. According to the CFTC press release, Tether held sufficient fiat reserves for only 27.6% of the days in a 26-month sample from 2016 through 2018.

The Q3 2026 attestation and 2025 audit show reserves above liabilities on those dates, but the risk remains. A stablecoin can trade below 1 dollar if confidence in the issuer or its reserves falls. Because most holders cannot redeem with Tether directly, in a sell-off they depend on the market price.

Access can also be cut off. Tether's terms let it freeze tokens held by a user when the law requires it or when Tether decides it is prudent.

USDT rules in the United States and the United Kingdom

United States

The GENIUS Act became law on 18 July 2025 as Public Law 119-27, the first federal framework for payment stablecoins. The Act requires permitted issuers to hold 100% reserves in liquid assets such as US dollars or short-term Treasuries, and to publish their reserve composition monthly. The Act takes effect on the earlier of 18 January 2027 or 120 days after the regulators issue final implementing rules.

From 18 July 2028, three years after enactment, digital asset service providers may not offer or sell a payment stablecoin to a person in the US unless it comes from a permitted issuer, with exceptions set out in the Act.

Tether launched a separate US-regulated token, USA₮, on 27 January 2026, issued by Anchorage Digital Bank, N.A.

On tax, the IRS treats digital assets, including stablecoins, as property and not currency (page updated 2 September 2026). Swapping, selling or spending USDT can be a reportable transaction, and Form 1040 asks whether you received or disposed of a digital asset. Brokers report gross proceeds on Form 1099-DA for transactions on or after 1 January 2025, and basis for certain transactions on or after 1 January 2026.

United Kingdom

The FCA says the UK's new cryptoasset regime, including stablecoin rules, comes into force on 25 October 2027. Firms can apply for authorization between 30 September 2026 and 28 February 2027. The FCA says that until the new rules apply, its oversight of crypto is limited to financial promotions and anti-money laundering controls.

The government's policy note says stablecoins issued overseas will be treated in line with other qualifying cryptoassets. The note does not name individual tokens.

On tax, HMRC says you may owe Capital Gains Tax when you dispose of cryptoasset tokens (guidance updated 5 October 2026). Disposal includes selling, swapping for a different cryptoasset, paying for goods or services, and giving away, except to a spouse, civil partner or charity. HMRC's current guidance does not single out stablecoins. HMRC's policy paper on the taxation of stablecoins, updated 28 October 2026, sets out a planned exemption from Capital Gains Tax for disposals of eligible stablecoins by individuals and trustees from 6 April 2027. Broadly, an eligible stablecoin keeps a stable value against a fiat currency, is supported by fiat or other assets, is widely available and is designed for payments. The paper does not name individual tokens, and the current disposal rules apply until then.

A note for readers in the EU

In January 2025 ESMA told EU crypto-asset service providers to stop making non-MiCA-compliant stablecoins available for trading by the end of the first quarter of 2025. On 8 October 2026 it said MiCA-authorized providers should stop all services for such stablecoins to clients in the EU, including transfers and custody, with existing exposures remediated within three months. The guidance is addressed to service providers, not owners.

You can check whether a stablecoin's issuer is authorized in ESMA's MiCA register.
