Stablecoins backed by transparent, fully funded reserves are relatively safe to use as digital money, but they are not risk-free. The main risk is that a stablecoin loses its peg, meaning it stops being worth one dollar, which usually happens when the reserves behind it are weak or unclear.
Understanding a few basics is enough to tell a sound stablecoin from a risky one.
What does "losing the peg" mean?
Losing the peg means a stablecoin that should be worth one dollar starts trading for less, for example 90 cents. This happens when people lose confidence that the token can be redeemed for a real dollar, often because the reserves backing it are insufficient or not verifiable.
A well-run stablecoin holds the peg because every token is matched by an equivalent real asset that can be redeemed.
What is the biggest risk?
The biggest risk is a stablecoin whose value is not backed by real, fully funded reserves. The collapse of TerraUSD (UST) in May 2022, which erased more than 40 billion dollars in days, was caused by an algorithmic design with no cash reserves behind it.
This is why the type of stablecoin matters: tokens backed 1:1 by cash and short-term securities are far more resilient than algorithmic ones.
What risks should a beginner know about?
There are four risks worth understanding.
RiskWhat it meansDe-peg riskThe token drops below its target valueReserve riskThe backing assets are weak or unverifiableCustody riskLosing access to your wallet or keysRegulatory riskA token is restricted in your country
For everyday use, reserve quality and custody are the two that matter most.
How do you keep your stablecoins safe?
You keep stablecoins safe by choosing a transparent, well-backed token and by protecting access to your wallet. Picking a stablecoin with regular reserve reports lowers de-peg risk, while keeping your wallet credentials secure prevents loss or theft.
Some wallets use technology called multi-party computation (MPC), which removes the single secret key that, if lost or stolen, would put your funds at risk.
How do you spot a trustworthy stablecoin?
A trustworthy stablecoin publishes regular reports on its reserves, is backed 1:1 by real assets, and complies with the rules where you live. In the European Union, for example, the MiCA regulation requires issuers to hold full reserves and report transparently, and USDC and EURC meet these rules.
If a stablecoin cannot clearly show what backs it, treat that as a warning sign.
