Is a stablecoin a cryptocurrency?

A stablecoin is a cryptocurrency in the sense that matters for most people: it lives on a blockchain, it is held in a crypto wallet and it can be traded on crypto exchanges. What sets it apart is that an issuer promises to keep its value steady, usually at one US dollar. In law, that promise moves stablecoins into a category of their own. How stablecoins keep their price is covered in what is a stablecoin.

Stablecoin vs cryptocurrency, what is the difference?

Most cryptocurrencies, such as bitcoin, have no issuer to redeem them and a price set only by trading. A stablecoin is the reverse. A company creates tokens when customers hand over dollars and destroys them when customers redeem. Circle, for example, says USDC is always redeemable one for one for US dollars and is backed mostly by a government money market fund.

So both are crypto tokens, but they behave differently. One is built to float, the other to stay flat. A side-by-side comparison with bitcoin is in bitcoin vs stablecoins.

What is the GENIUS Act payment stablecoin definition?

The GENIUS Act, the 2025 US stablecoin law, defines a digital asset as any digital representation of value recorded on a cryptographically secured distributed ledger. A stablecoin fits that description. The law then carves out a narrower group it calls payment stablecoins. These are digital assets designed for payment or settlement, where the issuer must redeem them for a fixed amount of money and says it will keep their value stable.

The definition excludes national currencies, bank deposits, including tokenized deposits, and securities. The law also says payment stablecoins are not backed by the full faith and credit of the United States or covered by deposit insurance, and it bars issuers from paying holders interest just for holding them. Covington's summary notes that stablecoins from permitted issuers are treated as neither securities nor commodities under federal law. More detail is in our GENIUS Act guide.

Do stablecoins count as crypto for taxes and regulation elsewhere?

For US taxes, yes. The IRS lists stablecoins among common digital assets that must be reported on a tax return, alongside cryptocurrencies and NFTs. That means a stablecoin trade can still be a reportable event, as covered in is swapping crypto taxable.

In the European Union, the MiCA regulation treats stablecoins as crypto-assets, split into two types. An e-money token references one official currency, such as the euro or dollar. An asset-referenced token references other values or a basket. Only banks and licensed electronic money institutions may issue e-money tokens, and the stablecoin rules have applied since June 30, 2024.

Rules differ by country and change often. Check the tax authority or a qualified professional for your own situation.
