Not financial, legal, or tax advice. Stablecoins are not risk-free despite the name.

Stablecoins are generally safer than volatile cryptocurrencies but are not risk-free. The main dangers are the coin losing its peg, the issuer failing to honor redemptions, and shifting regulation. Understanding these risks matters before treating any stablecoin as cash-equivalent. The Bank for International Settlements has documented how these failures unfold in practice.

De-peg risk

A stablecoin can temporarily, or in rare cases permanently, trade away from its target value if confidence in its backing or mechanism breaks down. Fiat-backed coins have historically de-pegged briefly during stress; algorithmic designs have de-pegged permanently. The three main designs differ sharply on exactly this point.

The distinction between those two outcomes is the whole subject. A fiat-backed coin de-pegs when the market doubts the reserves, and it recovers when the doubt resolves, because the reserves were there the entire time and redemption at face value eventually reasserts the price. USDC fell to about 88 cents in March 2023 when part of its reserves were trapped at a failed bank, then returned to a dollar within days once the deposits were made whole. Frightening, resolvable, and a useful demonstration that the mechanism works.

An algorithmic coin de-pegs and keeps going, because the mechanism holding the peg depends on confidence, and the de-peg is what destroys confidence. There is no floor to bounce off, which is why the 2022 collapse erased tens of billions in days rather than recovering. Same word, completely different event.

Issuer risk

A stablecoin is only as reliable as the entity backing it. If an issuer's reserves are insufficient, illiquid, or misrepresented, holders can be left unable to redeem at full value.

It is worth being blunt about what you own here, because the framing gets lost. A fiat-backed stablecoin is an unsecured IOU from a private company. It is not a dollar, not a bank deposit, and not insured by anyone. If the issuer fails, you are a creditor in a bankruptcy, standing in line, and the outcome depends on what the reserves actually held and who else has a claim on them. The token in your wallet is a claim, and the claim is only as good as the company behind it.

The reserves themselves carry ordinary financial risk on top of that. They sit in banks, which can fail, as 2023 demonstrated. They sit in Treasuries, which are safe but not instantaneous to liquidate at scale. And redemption is typically available only to large verified counterparties rather than to you directly, which means your practical exit is the open market, at whatever price the market offers on the day you need it.

Regulation

Stablecoin regulation is evolving in most major markets, and future rules could affect how certain coins operate, are issued, or are accessed. This uncertainty is itself a risk to factor in.

Stablecoins attract regulatory attention out of proportion to their size because they are the part of crypto that most resembles banking: taking deposits, issuing claims, investing the float. That is a regulated activity everywhere, for reasons that predate crypto by a century, and the direction of travel is toward reserve requirements, redemption rights, and licensed issuance rather than toward leaving it alone.

For holders, this is mostly good news with a sharp edge. Clearer rules make the reserves more trustworthy and the disclosures more meaningful. They can also strand a coin: an issuer that cannot or will not comply in a given jurisdiction may find its token delisted there, and holders may face a forced exit on someone else's timetable.

How to reduce risk

Favor stablecoins with frequent, credible reserve disclosures, avoid concentrating large amounts in a single issuer, and treat any double-digit "stablecoin yield" as a signal to investigate further rather than a free return. We compare how the two largest options report their reserves directly.

A few more habits worth adopting, in rough order of how much they matter:

  • Do not use stablecoins as a savings account. They pay you nothing while the issuer earns the interest on your money. For sitting in dollars long term, an actual dollar account is strictly better and insured.
  • Hold them where you control the keys when the amount matters. A stablecoin on a failed exchange is exposed to two failures rather than one, and the exchange is historically the likelier of the two.
  • Check the chain before sending. The same stablecoin exists separately on multiple networks, and mismatching them loses the funds permanently. This is the risk that actually costs ordinary people money.

The reasonable summary: stablecoins are excellent infrastructure and mediocre savings. They do one job very well, which is moving dollar-denominated value between places quickly and cheaply, and every risk above is a reason to keep the stay short rather than to avoid them.

Putting the risks in proportion

All of the above can read as a case against stablecoins, and it is not meant to. The largest ones have processed trillions of dollars in transfers, held their peg through a banking crisis, an exchange collapse, and a bear market, and recovered from every wobble within days. Measured against the volatile assets they sit alongside, they have been remarkably well behaved, and the sensible conclusion is calibration rather than avoidance.

So it is worth ranking what actually goes wrong. In practice, the most common way people lose money with stablecoins is sending them to the wrong chain, which is entirely self-inflicted and entirely preventable. The second is leaving them on a platform that fails, which is a custody decision rather than a stablecoin problem. A distant third is anything to do with the peg itself, and the losses there have overwhelmingly come from algorithmic designs rather than reserve-backed ones.

The name is the real hazard. "Stable" invites people to treat these as cash, and they are not cash: they are a claim on a company, denominated in dollars, that behaves like cash right up until it does not. Hold them for what they are good at, keep the amounts proportionate, and the risk is manageable. Treat them as a savings account and you have taken on a bank's risk profile for none of a bank's protections.
