In plain words

Think of a cloakroom ticket. You hand over your coat and get a ticket that is worth exactly one coat. You can pass the ticket to a friend, and whoever holds it can collect the coat. A fiat-backed stablecoin works the same way: you hand over a dollar, you get a token worth one dollar, and the token can move to anyone in seconds.

A stablecoin is a crypto token designed to keep a steady value, usually pegged one for one to a currency such as the US dollar or the euro. It lives on a blockchain, so it can be sent around the world at any hour, but unlike bitcoin its price is not supposed to move.

Whether the peg holds depends on what sits behind the token and whether the issuer will swap it back for real money. That is the first thing a founder, a partner bank or a regulator looks at.

How it works

How a fiat-backed stablecoin works

The token moves on the blockchain. The money behind it stays with the issuer.

  1. 1

    Money in, tokens out

    A verified customer, usually a business or an exchange, sends $1 million to the issuer. The issuer creates (“mints”) 1 million tokens.

  2. 2

    Reserves held

    The issuer holds the $1 million in reserves, such as bank deposits and short-term government debt, and reports on them regularly.

  3. 3

    Tokens move

    The tokens are sent, traded and used on the blockchain, between wallets, exchanges and apps, without the issuer being involved.

  4. 4

    Tokens back, money out

    A holder returns tokens to the issuer, which destroys (“burns”) them and pays out the money from reserves.

Three kinds of stablecoin

There are also stablecoins backed by commodities such as gold. Under EU rules, a token that tracks a basket of assets is an asset-referenced token, and one that tracks a single currency is an e-money token.

Why businesses use them

  • Cross-border payouts: sending value abroad in minutes, outside banking hours, often for less than a traditional transfer.
  • Treasury: holding a dollar balance without a US bank account, where local rules allow it.
  • Settlement: moving money between platforms and partners around the clock, including weekends.
  • Crypto trading: a stable unit to price and settle trades in, without converting back to bank money each time.

Reserves and redemption

Many retail users never deal with the issuer. They buy and sell on exchanges, so in a stress event the price they get is set by the market, not by the issuer’s promise. Regulation is closing that gap. In the EU, holders of e-money tokens have a legal right to redeem at par at any time, and issuers cannot pay interest. 1 Look for regular reserve reports or proof of reserves checked by an independent firm.

Stablecoins in the EU, UK and UAE

MarketStatusWho regulates
European UnionRegulated under MiCA since 30 June 2024. Only banks and EMIs can issue single-currency stablecoins 1National regulators; the EBA for significant tokens
United KingdomRegime being put in place. Stablecoin issuance and custody move into an FCA authorisation regime due to start on 25 October 2027, with separate Bank of England rules for systemic stablecoins 2 3FCA and Bank of England
UAESplit by location and activity. The Central Bank regulates payment tokens in mainland UAE; VARA covers virtual assets in Dubai outside the DIFC 4; the DIFC and ADGM have their own rulesCBUAE, VARA, DFSA, FSRA

Other Gulf markets are still setting their approach, so check with the local regulator before planning a launch there. For more depth, read the UK stablecoin moment and payment tokens in the UAE.

Example: paying suppliers abroad

Karim runs an import business in Dubai and pays a supplier in another country every month. His fintech app offers to settle the payment with a dollar stablecoin.

  1. On-ramp. Karim pays dirhams into the app. A licensed partner converts them into dollar stablecoins through an on-ramp.
  2. Transfer. The tokens move to the supplier’s exchange account in minutes, with sender and recipient details attached under the travel rule.
  3. Off-ramp. The supplier’s exchange converts the tokens into local currency and pays it to their bank account.
  4. Records. Karim’s app shows the exchange rates, fees and status of each step, so his accountant can match the payment to the invoice.

Common misconceptions

“A stablecoin is the same as money in a bank.”

It is a claim on an issuer’s reserves, not a bank deposit, and no deposit insurance applies. Tokenised deposits are the bank-deposit version.

“All stablecoins are equally stable.”

Stability depends on the reserves, the issuer and redemption rights. Algorithmic designs have failed completely.

“Adding stablecoins is just a new payment method.”

In most markets it brings new licences, partners and anti-money-laundering duties, and can change your whole launch route.

FAQ

What is a stablecoin in simple terms?

A stablecoin is a digital token on a blockchain that is designed to always be worth the same amount of a normal currency, usually one US dollar or one euro. It moves like crypto but is meant to hold its value like money.

Are stablecoins safe?

It depends on what backs them and who regulates the issuer. A stablecoin backed by cash and short-term government debt, with a regulated issuer and regular reserve reports, is much safer than one that relies on an algorithm. None of them is covered by deposit insurance.

What happens if a stablecoin loses its peg?

Its market price falls below the target, for example to 0.95 dollars. Holders who can redeem directly with the issuer may still get the full amount, but most users sell on exchanges and take the loss. Algorithmic stablecoins have collapsed completely after losing their peg.

Are stablecoins regulated in the UK?

The UK is bringing stablecoin issuance and custody into a new FCA authorisation regime due to start on 25 October 2027, and the Bank of England is setting separate rules for stablecoins used widely for payments. Until then, crypto firms register with the FCA for anti-money-laundering purposes and follow financial promotion rules.

Who can issue a stablecoin in the EU?

Under MiCA, a stablecoin tied to one currency is an e-money token, and only banks and electronic money institutions can issue it. A stablecoin tied to a basket of assets is an asset-referenced token and needs its own authorisation.

Can I use stablecoins for payments in the UAE?

In mainland UAE, payment tokens are regulated by the Central Bank of the UAE, which broadly allows dirham payment tokens for payments and limits how foreign-currency tokens can be used. Dubai's VARA, the DIFC and ADGM have their own rules, so the answer depends on where and how you operate.
