Tether (USDT) — A Practical Guide to the Largest Stablecoin
Tether (USDT) is the world's largest USD-pegged stablecoin by market capitalisation and circulating supply, with ~$140 billion in issued tokens as of early 2026. USDT is designed to maintain a stable 1:1 peg to the US dollar; each USDT is theoretically backed by an equivalent dollar of reserves held by Tether Limited (the Hong Kong / British Virgin Islands-based issuer). USDT runs natively on multiple blockchains — Ethereum (the largest issuance), Tron, Solana, Avalanche, Polygon, Binance Smart Chain and others — making it the most ubiquitous stablecoin in the crypto ecosystem.
USDT functions as the primary 'dollar' instrument inside crypto: most major centralised exchanges quote crypto prices in USDT pairs (BTC/USDT, ETH/USDT, etc.) rather than directly in fiat USD. This makes USDT effectively the unit-of-account for the entire crypto trading economy. Daily USDT transaction volume often exceeds the daily settlement volume of Visa.
History & contract origins
Tether was launched in 2014 as the first USD-pegged stablecoin, originally on the Bitcoin Omni layer. It moved to multi-chain issuance in 2018. Tether Limited has been the subject of recurring controversy about whether the reserves backing USDT are fully equivalent to USD; multiple legal proceedings in New York (2019-2021) ended with Tether Limited agreeing to publish quarterly attestations of reserves but not full third-party audits. Despite controversy, USDT has maintained its peg through every major crypto-market event with only brief temporary deviations (largest: down to ~$0.95 during the May 2022 Terra-Luna collapse, restored within days).
Major milestones: $1 billion supply (early 2018), $10 billion (mid-2020), $50 billion (mid-2021), $80 billion peak in May 2022, contraction to $65 billion after the Terra-Luna and FTX collapses in 2022, growth back to $140+ billion through 2024-25 driven by emerging-market USD demand and continued crypto-trading growth.

How to read this tape
Read USDT primarily for one thing: any deviation from the $1.00 peg. Persistent USDT discounts (USDT trading below $1.00) signal market stress and concerns about Tether Limited's reserves. Persistent USDT premiums (above $1.00) often signal emerging-market USD demand exceeding Tether's onshore issuance capacity. The USDT/USD spread on regulated venues (e.g. Coinbase USDT/USD pair, Kraken USDT/USD) is the primary peg-stability indicator.
USDT's role in crypto trading means its supply growth is a leading indicator of broader crypto-market liquidity. Periods of fast USDT supply expansion typically precede bull cycles; supply contraction often precedes corrections.
Frequently asked questions
Is USDT actually backed 1:1 by US dollars?
Tether Limited publishes quarterly attestations showing reserves backing all issued USDT. As of late 2025, reserves are primarily short-duration US Treasury bills, cash equivalents and a smaller share of secured loans and other assets. The exact composition is disclosed but not fully third-party audited. USDT has maintained its peg through every major stress event despite ongoing reserves debates.
What's the difference between USDT and USDC?
Both are USD-pegged stablecoins. USDT (Tether Ltd) is the larger and older; USDC (Circle, US-domiciled) is generally considered more regulatory-compliant and has full monthly attestations from major US accounting firms. USDC is widely used in DeFi and US-regulated venues; USDT dominates emerging-market and offshore exchange flows.
Can USDT lose its peg?
Briefly, yes — USDT has temporarily traded as low as $0.95 during major stress events (May 2022 Terra-Luna collapse, November 2022 FTX bankruptcy). Each time the peg has been restored within hours or days through Tether's redemption mechanism plus arbitrage activity.
Why is USDT popular in emerging markets?
Because it provides USD-denominated access to people in jurisdictions with capital controls or unstable local currencies (Argentina, Turkey, Nigeria, Venezuela). USDT can be sent peer-to-peer across borders 24/7 without traditional banking-system involvement, which is operationally valuable in EM contexts.
Can Indian residents hold USDT?
Yes — Indian exchanges (CoinDCX, WazirX, ZebPay) list USDT for INR-denominated trading. The 30% crypto tax + 1% TDS applies to any gains realised in USDT, even if you simply trade BTC into USDT. Consult a CA on cross-border USDT movement.
