Definition
A stablecoin is a type of cryptocurrency designed to maintain a stable value by pegging its price to a reference asset such as the US dollar or gold, reducing the price volatility associated with other cryptocurrencies.
Explanation
Stablecoins serve as the bridge between traditional finance and crypto markets, providing the transaction utility of blockchain technology without the price volatility of Bitcoin or Ethereum. USDT issued by Tether and USDC issued by Circle are the two largest stablecoins by market capitalization, both pegged one to one with the US dollar and backed by reserves held in traditional financial assets.
There are three main types of stablecoin: fiat-collateralized stablecoins backed by real currency reserves held in bank accounts, crypto-collateralized stablecoins backed by other cryptocurrencies with overcollateralization to absorb volatility, and algorithmic stablecoins that attempt to maintain their peg through automated supply adjustments. The algorithmic model has failed catastrophically in several high-profile cases.
Stablecoins are increasingly subject to regulation globally. The EU Markets in Crypto Assets regulation introduced comprehensive stablecoin oversight in 2024. The United States is developing federal stablecoin legislation as of 2026. Central banks cite private stablecoins as one motivation for accelerating their own CBDC development programs.
Example
A business receiving international payments accepts USDC stablecoin, holding the equivalent of US dollars on a blockchain that can be transferred instantly across borders at minimal cost, then converting to local currency when needed.
