Tether (USDT): Price and What It Is

Tether (USDT) is a stablecoin: a cryptocurrency designed to hold a value of one U.S. dollar per token. A USDT quote is therefore read differently from a quote for bitcoin or most other coins. The useful question is not whether the price went up or down. It is how far the price sits from $1.00 and why. A reading of $0.999 or $1.001 is normal trading noise. A sustained move of a cent or more signals stress in the market or doubt about the issuer.

What USDT Means

USDT is the ticker for Tether’s U.S. dollar token. “USD” refers to the dollar it tracks and “T” to Tether. In casual use “Tether” and “USDT” mean the same thing. Strictly, Tether is the company and USDT is its dollar product. Tether has also issued much smaller tokens pegged to the euro (EURT), the offshore Chinese yuan (CNHT) and the Mexican peso (MXNT).

The issuer is Tether, which sits under iFinex, the same parent company that operates the Bitfinex exchange. The project launched as RealCoin in July 2014 and took the Tether name in November 2014. The official website is tether.to. Similarly named domains are not the issuer.

Paying in USDT means sending Tether tokens from one blockchain address to another instead of sending dollars through a bank. The recipient gets a token that should be redeemable for, or tradable into, about one dollar. The transfer runs on a specific blockchain, which matters for the caveats below.

How to Read the USDT Quote

Most quote fields work as they do for any coin, but for a dollar-pegged token their meaning shifts:

• Price and percentage change: Because the target is $1.00, daily and yearly changes are tiny. A 0.05% move is a deviation of five hundredths of a cent. Read the price as distance from the peg rather than as performance.
• Market cap: Price multiplied by circulating supply. With the price near $1, market cap roughly equals the number of USDT in circulation, expressed in dollars. Growth in market cap mostly means new tokens were issued, not that the token gained value.
• Circulating vs. total supply: Total supply counts all tokens that exist. Circulating supply excludes tokens not treated as held by the market, such as those still held by the issuer.
• FDV (fully diluted value): Price multiplied by total supply.
• Max supply: no cap. There is no fixed limit. Tether creates (mints) tokens when customers deliver dollars and removes (burns) them when tokens are redeemed. Supply expands and contracts with demand.
• 24h volume: The dollar value of USDT traded across tracked markets in the past day. USDT is the quote currency for a large share of crypto trading pairs, so its volume reflects trading in other coins as much as interest in USDT itself.
• All-time high: On a stablecoin this is a past deviation above the peg, not a peak in value. It did not change what a token could be redeemed for.
• USDT dominance: USDT’s market cap as a share of the total crypto market cap. Because USDT’s own value barely moves, dominance tends to rise when other crypto prices fall and shrink when they rally, even if USDT supply is unchanged.

Converting USDT to Dollars

The conversion is a multiplication: amount of USDT × quoted price = dollar value.

Hypothetical example: at a quote of $0.9990, 2 USDT are worth 2 × 0.9990 = $1.998, effectively $2. At the same quote, 10,000 USDT are worth $9,990. On larger amounts the third and fourth decimal places start to matter.

The quote is a market average, not the amount you will receive. Converting on an exchange adds trading fees and the bid-ask spread. Withdrawing to a bank adds any withdrawal fee. Moving tokens on-chain costs a network fee, paid in the network’s own coin. Redeeming directly with Tether is a separate process open to verified customers, with its own minimums and fees.

How the Peg Is Supposed to Work

Pegged currencies are normally backed by reserves of the currency they track. USDT applies the same idea: Tether holds reserve assets and says each token is backed one-to-one.

The peg is held in practice by arbitrage between the issuer and the open market:

1. If USDT trades below $1 on exchanges, a verified customer can buy tokens cheaply and redeem them with Tether for $1. That buying pushes the market price back up.
2. If USDT trades above $1, a verified customer can deliver dollars to Tether, receive newly minted tokens at $1 and sell them higher. That selling pulls the price down.

This only works while redemptions are honored and traders believe the reserves can cover them. The mechanism explains why deviations are usually small and short. It does not guarantee they will be.

What Moves USDT Off $1

Several forces can push the market price away from the peg:

• Confidence in reserves. If holders doubt the backing, they sell on exchanges instead of waiting to redeem, and the price drops.
• Market stress. In May 2022, after the TerraUSD (UST) stablecoin lost its peg, USDT briefly fell to as low as $0.96, although TerraUSD had no connection to Tether or Bitfinex. It recovered to above $0.99 within a short time, and Tether said it kept processing redemptions at one to one. When the FTX exchange collapsed in November 2022, USDT dipped to around $0.995, then rebounded and at times traded above $1.
• Flight to safety. During sharp crypto sell-offs, traders who sell volatile coins often move into stablecoins. That demand can lift USDT slightly above $1 until new issuance catches up.
• Friction. Fees, the time to complete a redemption and limits on who can redeem all slow arbitrage. The greater the friction, the wider and longer a deviation can run.

Reserves and Transparency

Tether publishes a breakdown of its reserves on its website. Its reports have listed a mix of assets rather than dollar cash alone. The bulk has been cash, cash equivalents and short-term deposits, with U.S. Treasury bills the largest component. Reports have also listed precious metals, bitcoin, secured loans, public equities and other investments. Treasury bills are low-risk and liquid. Bitcoin, metals and loans can lose value or take time to sell.

That composition is why the one-to-one claim deserves a qualifier. The token is backed by a portfolio whose value can move, not by a matching pile of dollars. Tether has generally honored its one-to-one redemption commitment, including during the 2022 market shocks.

Tether’s Regulatory Record

In 2021 Tether and Bitfinex settled with the New York Attorney General. They paid $18.5 million and agreed to stop doing business with New York residents and entities. The investigation had found that Bitfinex borrowed at least $700 million from Tether’s reserves. The same year, the CFTC fined Tether $41 million over claims that USDT was fully backed by dollars. It found that fiat reserves covered the tokens in circulation on only 27.6% of the days in a 26-month sample from 2016 through 2018. That record is one reason confidence in the reserves weighs on the quote.

How USDT Differs From Other Crypto and From a Bank

Most cryptocurrencies, such as bitcoin or ether, float freely, and their prices reflect supply and demand with no target. USDT is meant to be only as volatile as the dollar itself. That lets traders park value between trades without converting back to a bank account, and it gives exchanges a common unit for pricing other coins.

Other dollar stablecoins work differently. USD Coin (USDC) is also issuer-backed but comes from a different company with its own reserve reporting; the USDC overview explains its structure. Dai (DAI) is created through a decentralized protocol against crypto collateral rather than by a single company.

USDT is not a bank deposit. A dollar balance at a U.S. bank is a claim on a regulated bank and is covered by FDIC insurance up to the legal limit. USDT is a claim on Tether, governed by its own terms, with no deposit insurance. Tether controls the token contracts, so it can freeze tokens at specific addresses. It has cooperated with law enforcement agencies in this way.

Buying, Holding and Sending USDT

USDT is sold on major crypto exchanges, and some online brokerages offer crypto as well. A comparison of crypto exchanges and apps covers fees and features. Most buyers acquire USDT on an exchange rather than from Tether, because direct issuance and redemption are reserved for verified customers.

Since moving beyond the Omni Layer, USDT has been issued on many blockchains, including Ethereum, TRON, Solana, Avalanche, Polygon, Algorand, Tezos, EOS, Kava and Polkadot. Each version is the same dollar token on a different network, but the networks do not talk to each other directly. A few practical rules follow:

• Match the network. When sending or receiving, both sides must use the same blockchain. Tokens sent to an address on the wrong network can be lost or require a costly recovery.
• Budget for network fees. Fees are paid in the network’s own coin (ETH on Ethereum, TRX on TRON), so you need a small balance of that coin to move USDT from a self-custody wallet.
• Know where your tokens sit. USDT held on an exchange depends on both the exchange and Tether. In a self-custody wallet it depends on Tether and on your control of the keys.
