What Are Stablecoins? How They Work and Key Risks

A stablecoin is a crypto asset designed to maintain a relatively stable value compared with a reference asset, most commonly the U.S. dollar. Stablecoins can make it easier to transfer dollar-denominated value across blockchain networks and move between crypto assets without using a traditional bank transfer for every trade.

“Stable” describes the design objective, not a guarantee. A stablecoin can trade above or below its target, become difficult to redeem, suffer a smart-contract failure, or collapse if its reserves or stabilization mechanism prove inadequate.

How Do Stablecoins Work?

Most dollar-referenced stablecoins attempt to keep a market price near one dollar through issuance and redemption. When eligible customers deposit dollars or approved reserve assets with an issuer, new tokens may be created. When tokens are redeemed, they are removed from circulation and the customer receives the corresponding value under the issuer’s terms.

If market participants trust that redemption will occur near one dollar, price differences can create an incentive to buy below the peg or sell above it. That mechanism can weaken when confidence, liquidity, or access to redemption deteriorates.

Types of Stablecoins

Fiat-Backed Stablecoins

An issuer holds reserves intended to support redemption at the reference value. Reserves may include bank deposits, short-term government securities, repurchase agreements, or other permitted assets. The quality, liquidity, custody, transparency, and legal treatment of those reserves matter.

Crypto-Collateralized Stablecoins

Crypto assets are locked in smart contracts as collateral. Because the collateral can be volatile, these systems often require more collateral than the stablecoins issued and may liquidate positions when values fall.

Algorithmic or Under-Collateralized Stablecoins

Some designs rely primarily on trading incentives, supply adjustments, or a relationship with another token rather than fully reserved assets. These mechanisms can enter a feedback loop when confidence disappears and have historically presented substantial de-pegging risk.

Commodity-Referenced Tokens

Some tokens attempt to track gold or another commodity. Their risks differ from dollar stablecoins and may include custody, valuation, redemption, and geographic restrictions.

What Are Stablecoins Used For?

• Trading between crypto assets using a dollar-denominated pair
• Moving value between compatible platforms or wallets
• Blockchain-based payments and settlement
• Holding a less volatile crypto-market position between trades
• Providing collateral or liquidity in decentralized-finance applications
• Cross-border transfers, subject to legal and platform restrictions

A stablecoin may reduce exposure to Bitcoin-like price swings while introducing different risks involving the issuer, reserves, redemption, blockchain, and smart contracts.

Are Stablecoins the Same as Bank Deposits?

No. A stablecoin is not automatically a bank deposit, and holding one does not by itself provide FDIC insurance. Reserve assets may be held at banks or in government securities, but that does not mean every token holder has a direct insured claim on those assets.

The Federal Reserve’s analysis of stablecoin developments and financial-stability risks emphasizes that reserve quality, liquidity, redemption, and reliance on service providers vary across issuers.

Stablecoin Risks

De-Peg and Redemption Risk

A token can fall below its target when holders doubt the reserves, issuer, collateral, or redemption process. Even a reserve-backed stablecoin can experience stress if reserve assets become illiquid or access to banking and settlement services is disrupted.

Issuer and Counterparty Risk

Centralized stablecoins rely on an issuer, reserve custodians, banks, auditors or assurance providers, and other service providers. A failure or legal restriction affecting one participant can affect token holders.

Smart-Contract and Blockchain Risk

A bug, exploit, network outage, bridge failure, or transaction sent on the wrong network can cause loss even if the underlying reserves remain intact.

Liquidity Risk

The market price shown on a platform may not be available for a large or urgent transaction. Redemption may be limited to eligible direct customers, leaving other holders dependent on secondary-market liquidity.

Freezing and Compliance Controls

Some issuers can freeze addresses or decline redemptions to comply with law, sanctions, court orders, or platform terms. That control may help address theft and illicit activity but also means the asset is not censorship-resistant in the same way as some decentralized cryptocurrencies.

How to Evaluate a Stablecoin

• What asset does it attempt to track?
• Who issues it and who can redeem directly?
• What assets back it, and where are they held?
• How frequently are reserve reports or third-party assurance reports published?
• What fees, minimums, delays, or eligibility rules apply to redemption?
• Which blockchains and token contracts are official?
• Can the issuer freeze or blacklist addresses?
• Has the token lost its peg or experienced a security incident?

Stablecoins in a Cryptocurrency IRA

A supported stablecoin may allow an IRA holder to maintain a dollar-referenced crypto position between trades without withdrawing funds from the retirement account. It does not turn cryptocurrency into insured cash or eliminate custody and issuer risk.

Coin IRA currently supports USDC among its available cryptocurrencies. Availability can change, so verify the current asset list and account terms. USDC’s issuer publishes information about reserves and assurance reporting on its transparency page.
