Stablecoins are cryptocurrencies built to hold a steady value, and that target is called the peg. People use them for trading, payments, and holding dollars outside a bank, because the price barely moves.
What is stablecoin depegging?
A stablecoin depegs when its market price moves away from its peg, usually below the target and sometimes above it. The peg is usually a national currency, most often the US dollar.
Why do stablecoins lose their peg?
A peg holds when reserves or algorithms keep supply and demand in balance. During a depeg the token still exists and trades at a discount, and the issuer may pause redemptions.
- Reserve doubts: holders question whether the issuer holds enough safe assets.
- Redemption delays: the issuer slows or limits withdrawals.
- Panic: holders sell below the peg to exit quickly.
- Broken arbitrage: traders stop buying the discount.
How can you tell a wobble from failure?
A brief wobble and a real failure can look alike at first. The issuer's actions and the time spent below the peg tell them apart.
How is a depeg different from a crash?
A normal crypto crash is a fall in price with no fixed target. A depeg is different because the peg is the product, and losing it means the coin failed at the one job it has.
What do US rules say about stablecoins?
US stablecoin rules are still developing, and they affect redemption rights and disclosures. What you can do during a depeg depends on the issuer's terms and on the state and federal rules that apply to it.
Regulators have debated who may issue a stablecoin, what reserves it must hold, and what it must publish. Those rules keep changing.
