Key takeaways
- A stablecoin is a digital token designed to hold a steady value, usually one US dollar.
- Fiat-backed stablecoins are only as good as their reserves, their redemption rights and the issuer behind them.
- For businesses, the appeal is speed, global reach and lower costs than many traditional payment rails.
- Regulation is now arriving in major markets, setting rules for reserves, disclosures and who may issue.
Cryptocurrencies like Bitcoin and Ether are known for price swings. That volatility makes them hard to use for everyday payments: nobody wants an invoice to lose 5% of its value between sending it and getting paid. Stablecoins were created to solve that problem.
What is a stablecoin?
A stablecoin is a digital token, issued on a blockchain, that is designed to maintain a stable value relative to a reference asset. Most stablecoins track the US dollar, aiming for one token to be worth one dollar. Well-known examples include USDC, issued by Circle, and USDT, issued by Tether. DAI is a decentralised stablecoin that uses a different mechanism.
Because they live on blockchains, stablecoins can be sent between wallets at any time, settle in minutes or seconds, and move across borders without passing through a chain of correspondent banks.
How stablecoins hold their value
There are three broad designs.
| Type | How it holds value | Examples |
|---|---|---|
| Fiat-backed | Each token is backed by reserves such as cash and short-term government securities held by the issuer | USDC, USDT |
| Crypto-collateralised | Tokens are backed by other crypto assets locked in smart contracts, usually over-collateralised | DAI |
| Algorithmic | Supply is expanded or contracted by an algorithm, with little or no collateral | Largely discredited after high-profile failures |
Fiat-backed stablecoins are by far the most widely used. Their stability depends on three things:
- Reserves: the issuer holds assets at least equal to the tokens in circulation, ideally in cash and very short-term, high-quality government debt.
- Redemption: holders, or at least eligible holders, can exchange tokens for dollars at par.
- Transparency: the issuer regularly discloses what the reserves are, ideally with independent attestation or audit.
When markets trust all three, arbitrage keeps the price close to one dollar: if the token trades below a dollar, buyers can profit by acquiring tokens and redeeming them.
Why businesses use stablecoins
For a business, stablecoins combine the stability of a currency with the reach of the internet.
- Faster settlement: payments confirm in minutes, including weekends and holidays, instead of the days an international wire can take.
- Lower costs: settling on-chain can remove intermediary fees. Some platforms pass this through; BitInvoices, for example, offers processing fees as low as 0% on stablecoin payments.
- Global reach: a customer anywhere with a wallet can pay, without the merchant needing a bank relationship in that country.
- Programmability: payments can be tracked, matched and reconciled automatically, and every transfer leaves a verifiable record on-chain.
Common use cases include cross-border invoicing, paying international contractors, treasury management and settlement between businesses.
The risks to understand
Stablecoins are not risk-free, and responsible use starts with understanding where things can go wrong.
- Reserve and issuer risk: if reserves are insufficient, illiquid or poorly managed, a stablecoin can lose its peg. Holders depend on the issuer's governance and the protections in place if it fails.
- Depegging: even well-reserved stablecoins can trade briefly below par during market stress, for example if a bank holding part of the reserves runs into trouble.
- Operational risk: sending funds to the wrong address or on the wrong network can be irreversible.
- Regulatory risk: rules on who can issue, hold or offer stablecoins vary by jurisdiction and are still evolving.
- Accounting and tax: treatment differs by jurisdiction, so businesses should take professional advice.
Practical safeguards help. Pricing invoices in a fiat currency and locking the exchange rate at checkout means a business receives what it billed. Keeping an auditable record of each payment (amount, rate, sending address, transaction hash and confirmations) makes reconciliation and audits much simpler.
Regulation is catching up
For years stablecoins operated in a regulatory grey area. That is changing. The European Union's Markets in Crypto-Assets Regulation (MiCA) now sets rules for issuers of fiat-referenced tokens, and the United States enacted the GENIUS Act in July 2025, creating a federal framework for payment stablecoins. Hong Kong, Singapore and others have introduced their own regimes.
The common themes are full reserve backing with high-quality assets, regular public disclosure of reserves, clear redemption rights, and anti-money laundering obligations for issuers. We look at these frameworks in more detail in Stablecoin regulation around the world.
The bottom line
Stablecoins give businesses a way to move dollars at internet speed. The value of that depends on choosing well-reserved, transparent stablecoins, using tools that manage rate and operational risk, and working with providers that take compliance seriously.
