Stablecoin Risks: Depegs, Reserves and Regulation
Stablecoins are meant to be boring — until they are not. Here are the main ways they can break, and what a healthy one looks like.

- A stablecoin can "depeg" — lose its 1:1 value — if trust in its backing breaks.
- Reserve quality matters: cash and short-term treasuries are safer than opaque assets.
- Algorithmic stablecoins have failed spectacularly, most notably TerraUSD in 2022.
- Regulation is tightening worldwide, which could reshape which stablecoins survive.
Stablecoins are designed to be the calm corner of crypto. Most of the time they are. But “stable” is an aim, not a promise, and it is worth understanding how they can wobble before relying on one.
Depegs
A depeg is when a stablecoin drifts away from its target value. It can be brief and technical — a moment of thin liquidity — or a genuine crisis of confidence. Algorithmic stablecoins that lack real reserves have suffered the most severe, permanent collapses, wiping out holders. Even well-run reserve-backed coins can briefly slip during market stress before arbitrage restores the peg.
Reserves and transparency
For a fiat-backed stablecoin, the peg is only as good as the reserves behind it. Key questions: what exactly backs the token, is it truly one-for-one, how liquid are those assets, and who verifies them? Regular, credible attestations or audits are a healthy sign; opacity is a warning.
Regulation and access
Stablecoins increasingly sit under regulatory scrutiny around the world, which can affect who may issue them, what reserves they must hold, and whether you can redeem them. That is broadly a move toward safety, but rules differ by region and continue to evolve.
The takeaway
Treat stablecoins as tools with real, if usually low, risk. Prefer transparent, reserve-backed coins, and never assume a peg is unbreakable. See the stablecoins we track on our stablecoins hub. Not financial advice.
