A stablecoin is a cryptocurrency designed to hold a steady value, usually pegged to a fiat currency like the US dollar at a one-to-one rate.
A stablecoin is a type of cryptocurrency engineered to maintain a stable price, most often pegged to a fiat currency such as the US dollar.
There are several designs. Fiat-backed stablecoins hold cash and equivalents in reserve to back each token. Crypto-backed stablecoins are over-collateralised with other cryptocurrencies. Algorithmic stablecoins try to hold the peg through supply-and-demand mechanisms, which have historically proven riskier.
Stablecoins are widely used to move value between exchanges, park funds during volatility, and provide liquidity in decentralised finance, all without converting back to a bank account.
The main risk is whether the peg holds. Reserve quality, transparency, and the mechanism behind the coin all affect how reliably it stays near its target value.
A trader expecting a market drop sells 1 BTC at $60,000 for 60,000 units of a dollar-pegged stablecoin. While prices fall, those units stay near $1 each rather than dropping with crypto. When the trader is ready to buy back in, they convert the stablecoins to BTC without ever touching a bank.
Most stablecoins maintain their peg by holding reserves, such as cash or other cryptocurrencies, that back each token. Algorithmic stablecoins instead adjust supply through code, a design that has historically been more fragile.
Stablecoins are designed to be stable, but they are not risk-free. The peg can break if reserves are insufficient or untrustworthy, so reserve quality, transparency and the coin's mechanism all matter when judging reliability.
