Stablecoin Risks & Losses
A stablecoin is a type of cryptocurrency designed to maintain a fixed value, usually one U.S. dollar, by holding reserves or using algorithmic mechanisms to offset price movements. Stablecoins are issued by companies like Tether, Circle, Paxos, and PayPal, and are sold through crypto exchanges, yield platforms, and increasingly through financial advisors who recommend them to clients seeking cash alternatives or higher yields. Stablecoins fall into four main categories. Fiat-backed stablecoins like USDT (Tether) and USDC (Circle) claim to hold cash and short-term U.S. Treasuries equal to every token in circulation. Crypto-collateralized stablecoins like DAI require users to lock up crypto assets worth more than the stablecoins they mint. Algorithmic stablecoins like the collapsed TerraUSD relied on code and a paired token rather than reserves. Yield-bearing stablecoins like Ethena USDe and Ondo USDY pay holders interest generated from Treasuries or derivatives strategies. The global stablecoin market reached approximately $318 billion in early 2026, with Tether holding about 60% market share and USDC about 25%. Stablecoin issuers collectively are now the seventh-largest purchasers of U.S. government debt. That growth has coincided with more than $50 billion in investor losses from failed platforms and algorithmic collapses.
