If you have ever watched Bitcoin's price jump or drop by thousands of dollars in a single day, you can see why the crypto world wanted a digital token that simply stays at $1.
Those tokens, called stablecoins, have grown into a market worth about $308 billion, and starting January 18, 2027, issuing one in the U.S. will require a federal or state license.
What Is a Stablecoin?
A stablecoin is a type of cryptocurrency designed to hold a steady value, usually $1, typically by keeping reserves of cash and short-term U.S. government debt behind every coin.
Like other crypto, it lives on a blockchain, a shared digital ledger run by many computers, so it can be sent to anyone in the world at any hour.
That $1 target is called the peg, and a coin that drifts away from it is said to have broken its peg.
Picture a company that sells you 1,000 digital tokens for $1,000, then parks your money in a bank account and in Treasury bills, which are short-term loans to the U.S. government.
Each token is now backed by $1 sitting in reserve, so when you want out, you hand back the tokens and the company returns your $1,000.
Meanwhile, you can send those tokens to anyone with a crypto wallet, and as long as people trust the reserve is really there, each token keeps trading at $1.
The company earns its profit by keeping the interest on those Treasury bills, which is the core business model for the largest issuers.
How Do Stablecoins Keep Their Value?
If a stablecoin dips to 99 cents on the open market, traders can buy it cheaply and redeem it with the issuer for a full $1, and that buying pushes the price back up.
If it climbs to $1.01, the issuer can create new coins for $1 each and sell them, which pulls the price back down.
That system works only as long as people believe the reserves are real and that they can cash out when they want, which is why reserves get so much scrutiny.
Why Do Stablecoins Matter to You?
Stablecoins let people hold and move dollars on a blockchain, which matters most where traditional banking is slow, expensive, or out of reach.
Sending money abroad the traditional way has long been costly: the World Bank has tracked the global average cost of sending $200 to another country at roughly 6% for years.
A stablecoin transfer can arrive in minutes for a fraction of that, though converting to and from local cash can add fees of its own.
Inside crypto markets, stablecoins also work as a parking spot, letting traders step out of volatile coins without moving money back to a bank.
The Main Types of Stablecoins
Fiat-Backed Stablecoins
These are backed by fiat currency, meaning government-issued money like the U.S. dollar, along with cash-like assets such as Treasury bills.
Tether's USDT and Circle's USDC, the two largest stablecoins, both follow this model.
Crypto-Backed Stablecoins
These are backed by other cryptocurrencies locked into a computer program, with extra collateral as a cushion, such as $150 worth of ether behind every $100 of stablecoins.
DAI is the best-known example, and while the cushion helps, a fast crash in the collateral can still strain the peg.
Algorithmic Stablecoins
These try to hold $1 using code that creates and destroys a companion token instead of holding full reserves.
TerraUSD, the most famous example, collapsed in May 2022 after luring buyers with interest of up to 20%, and the Securities and Exchange Commission later charged its creators with fraud.
How Does the GENIUS Act Protect Stablecoin Holders?
The GENIUS Act, signed in July 2025, is the first federal law written specifically for stablecoins used in payments.
One-for-One Reserves
Issuers must hold at least $1 in reserves for every coin, limited to safe assets such as cash, bank deposits, and Treasury bills that mature in 93 days or less.
Monthly Reserve Reports
Issuers must publish the makeup of their reserves every month, so holders can see what actually backs their coins.
No Interest From Issuers
Issuers can't pay holders interest just for holding the coin, a rule meant to keep stablecoins working as payment tools rather than savings accounts.
Exchanges and other platforms can still offer rewards on stablecoin balances, and the Senate bill that would have restricted those rewards stalled in September 2026.
Licensing Deadlines
Starting January 18, 2027, only licensed issuers can create payment stablecoins in the U.S.
By July 2028, crypto platforms serving Americans will be allowed to offer only stablecoins from issuers approved under the law.
Is a Stablecoin the Same as Money in a Bank?
No, and treating one like a bank deposit is the most costly mistake a beginner can make.
FDIC insurance, the federal guarantee that protects bank deposits up to $250,000 per depositor, per bank, per ownership category, does not cover crypto assets, and the FDIC has warned that this holds even when a crypto company works with a bank.
If an issuer fails, your money depends on its reserves rather than a government backstop, though the GENIUS Act does put holders first in line for those reserves in a bankruptcy.
A stablecoin's $1 price is a target, not a promise anyone can guarantee.
What Can Go Wrong With a Stablecoin?
The Peg Can Break
In March 2023, USDC fell to about 87 cents after Circle disclosed that $3.3 billion of its roughly $40 billion in reserves was stuck at the failed Silicon Valley Bank.
It recovered within days once regulators guaranteed the bank's deposits, but anyone who sold during the panic locked in a real loss.
Reserves May Not Match the Marketing
In 2021, the Commodity Futures Trading Commission fined Tether $41 million, finding its coins were not fully backed for most of the period from 2016 to 2019.
Tether settled the case and has maintained that it always held adequate reserves, but the episode is why the new monthly reporting rules matter.
Mistakes Are Hard to Undo
Like other crypto, a stablecoin sent to the wrong address usually can't be pulled back.
There is no bank or card company to call for a refund, so double-checking every address before you hit send is essential.
How Do You Buy a Stablecoin?
You can buy stablecoins through a crypto exchange, an app that works like a brokerage account for digital assets and links to your bank account so you can trade dollars for coins.
Before you buy, check which stablecoin you are getting, since reserve quality differs from issuer to issuer, and favor coins whose issuers publish monthly reserve reports.
If you want to start with a well-known option, Gemini lets you buy, hold, and send stablecoins such as USDC, and you can begin with a small amount while you learn how transfers work.
Once you own one, watch its price: a stablecoin trading well below $1 for more than a few hours is a warning sign about its reserves, not a bargain.
