What Is a Stablecoin?

A stablecoin is a token engineered to hold a fixed value, almost always one U.S. dollar. It is crypto's working money: the unit people trade against, park in between positions, and send across borders. USDT (Tether) and USDC (Circle) dominate, with tens of billions in daily use.

How It Actually Works

Fiat-backed: the issuer holds reserves, cash and short-term Treasuries, and redeems tokens one-for-one. The peg holds because arbitrage against redemption is riskless when reserves are real. This is the model U.S. law now blesses.
Crypto-collateralized: DAI-style coins backed by overcollateralized crypto locked in contracts. More transparent, more complex, exposed to collateral crashes.
Algorithmic: pegs maintained by mint-and-burn incentives with a sister token. TerraUSD's $40 billion collapse in 2022 is the permanent cautionary tale: when confidence broke, the mechanism amplified the death spiral.

The Rules Arrived

The GENIUS Act, signed July 2025, created the first federal framework: payment stablecoin issuers must hold full high-quality reserves, publish disclosures, and submit to oversight, and compliant payment stablecoins are explicitly not securities. My securities guide covers the classification; the practical upshot is a widening gap between regulated coins and everything else.

Risks and Common Mistakes

Depegs happen. Even USDC wobbled to 88 cents for a weekend in 2023 when a reserve bank failed. Brief wobbles differ from death spirals, but if you must sell during one, the discount is yours.
Not deposit insurance. No stablecoin is FDIC or NCUA insured, full stop; my insurance guide explains. Reserves reduce risk; they do not federalize it.
Yield-bearing "stablecoins" are investment products wearing a savings costume. Ask what generates the yield and who eats the loss.
Issuers can freeze addresses on major coins, a feature for law enforcement and a fact worth knowing about your money.

When It Matters

Trading, parking dry powder (the portfolio page use case), payments, and DeFi, where stables are the base collateral. Check reserve reports occasionally: Circle's and Tether's are both linked in my Resource Library.
