The Tether peg refers to USDT's 1:1 price relationship with the US dollar. Unlike volatile cryptocurrencies such as Bitcoin or Ethereum, USDT is engineered to remain at exactly $1.00 at all times. This stability is achieved through a combination of full reserve backing, active redemption mechanisms, and market arbitrage — making USDT the world's most widely used stablecoin with over $184 billion in market capitalization as of 2026.
Tether Limited maintains the peg by holding reserves equal to or greater than the total supply of USDT in circulation. Every time a user deposits USD, Tether issues the equivalent USDT. When a user redeems USDT, the tokens are burned and USD is returned. This mint-and-burn cycle, combined with a deep arbitrage market across exchanges, keeps USDT within fractions of a cent of its $1 target at all times.
How the Tether Peg Works
PEG MECHANISM
USDT holds close to $1 because of an arbitrage loop that depends on redemption confidence and liquidity. When USDT trades above $1 on an exchange, arbitrageurs deposit USD directly with Tether, receive freshly minted USDT, then sell on the open market — pushing the price back down. When USDT trades below $1, traders buy discounted USDT on the open market and redeem it with Tether for exactly $1 — pushing the price back up. This two-sided arbitrage mechanism self-corrects any deviation from the peg within minutes. Tether's Q4 2025 BDO-prepared attestation confirms reserves of over $181 billion against $174 billion in liabilities, providing a $6.8 billion buffer of excess equity that further reinforces peg stability.
