# Stablecoin

A **stablecoin** is a crypto asset designed to hold a fixed value against
a reference asset, usually one US dollar. Most large stablecoins, such as
[Tether](tether.md)'s USDT and [USDC](usdc.md), are issued by companies
that hold reserves of cash and short-term government debt. Others are
minted against crypto collateral, hedged with derivatives, or held to
their target by incentives alone, the design of TerraUSD, which collapsed
in May 2022.[^fed-stable][^nber-terra] The Bank for International
Settlements (BIS) estimated in 2026 that about 98% of stablecoin value
was denominated in dollars.[^bis-170] The United States, the European
Union, and other jurisdictions now regulate issuers directly, while
central banks dispute whether stablecoins can serve as money at
all.[^genius][^mica-149][^bis-aer]

## Definition

There is no single definition. The GENIUS Act defines a "payment
stablecoin" as a digital asset that is, or is designed to be, used as a
means of payment or settlement, whose issuer is obligated to redeem it
for a fixed amount of monetary value, and which the issuer represents
will hold a stable value. The definition excludes national currency,
deposits, and securities.[^genius] The EU's Markets in Crypto-Assets
Regulation (MiCA) has two legal categories: an e-money token references
one official currency, and an asset-referenced token references another
value or right, or a combination of them.[^mica-3]

The BIS argues that stablecoins behave like financial assets rather than
money. Its 2025 annual report says they typically fail the test of
singleness, because they do not always trade at par with one another,
and also fail the test of elasticity. It concludes that they "perform
poorly when assessed against the three tests for serving as the mainstay
of the monetary system".[^bis-aer] Gorton and Zhang compare them to the
privately issued banknotes of nineteenth-century America.[^gorton]

## History

### Early designs

The Block dates BitUSD, a token collateralised by BitShares, to July
2014 and describes it as the earliest mainstream stablecoin. It lost its
peg in November 2018 and did not recover.[^block-bitusd] Realcoin was
announced that same month, July 2014, and was renamed Tether in November
2014.[^realcoin][^rebrand] NuBits began in September 2014 and held its
peg for about twenty months before falling below 50 cents in
2016.[^nubits]

MakerDAO launched Dai on Ethereum on 18 December 2017, backed solely by
ether.[^coindesk-dai] Multi-Collateral Dai went live on 18 November
2019, starting with ether and Basic Attention Token as collateral. It
took the Dai name, the older token was renamed Sai, and the launch added
the Dai Savings Rate.[^block-mcd]

Basis raised US$133 million for an algorithmic stablecoin and shut down
in December 2018, returning unspent money. Its chief executive said
lawyers had concluded its bond and share tokens could not avoid being
securities.[^techcrunch-basis]

### Libra and the regulatory response

Facebook announced Libra on 18 June 2019, with a planned association of
28 founding members, among them Visa, Mastercard, PayPal, and
Uber.[^coindesk-libra] The project, later named Diem, confirmed its
shutdown on 31 January 2022, selling its technology to Silvergate. Its
chief executive, Stuart Levey, said talks with federal regulators had
made clear that it could not launch.[^coindesk-diem]

### Terra and the 2022 collapses

Algorithmic designs failed repeatedly in this period. Iron Finance's
IRON broke its peg on 16 June 2021 in what Federal Reserve staff
analysed as a run.[^fed-iron] [Terra](terra.md)'s UST lost its peg in May
2022; Liu, Makarov, and Schoar describe the unwinding as a run in which
redemptions inflated the supply of its LUNA token.[^nber-terra] USDN and
HUSD also lost their pegs in 2022.[^ct-usdn][^block-husd]

### Regulation and institutional issuers

In March 2023 the failure of Silicon Valley Bank, which held about 8% of
USDC's reserves, pushed USDC to about 86 cents until US authorities
protected depositors.[^fed-svb] US legislation followed in July 2025
with the GENIUS Act.[^genius] Banks and payment firms have also entered
the market: PayPal in 2023, SoFi Bank in December 2025, and Open USD, whose
partners include Coinbase, Mastercard, and Visa, on 30 September
2026.[^paypal-launch][^block-sofi][^unchained-ousd][^coindesk-openusd]

Federal Reserve staff put aggregate stablecoin market capitalisation at
US$317 billion on 6 April 2026 and said growth had flattened in late
2025 and early 2026.[^fed-2025] Current totals are on
[DefiLlama](https://defillama.com/stablecoins), which tracked more than
400 pegged assets in October 2026.[^llama]

## Types

Federal Reserve staff sort stablecoins by how they are stabilised:
off-chain collateralised, on-chain collateralised, and uncollateralised
or algorithmic. They conclude that a run driven by sentiment alone
disappears only when the collateral matches the currency of the
peg.[^fed-stable]

### Reserve-backed

The issuer holds cash, bank deposits, government debt, or money market
funds, and redeems tokens for fiat with approved customers. Holders rely
on the issuer's solvency, its banks, and the accuracy of its
disclosures. Federal Reserve staff say arbitrage for these coins breaks
down once the market loses faith in the peg.[^fed-stable]

### Crypto-collateralised

Users lock crypto in smart contracts and mint stablecoins against it,
usually with more collateral than debt. Positions that fall below a
required ratio are liquidated. Federal Reserve staff say these designs
"might experience more frequent and pronounced runs".[^fed-stable]
Liquity's LUSD adds a floor by letting holders redeem it for ether at
face value.[^liquity-redemption]

### Synthetic

Ethena's USDe is described by its issuer as "a synthetic dollar, backed
with crypto assets and corresponding short futures positions", and it
distinguishes this from fiat-backed stablecoins.[^ethena-overview] Its
documentation attributes USDe's peg stability to delta-neutral hedges of
the underlying assets.[^ethena-docs]

### Algorithmic

Uncollateralised designs hold few or no reserves and rely on supply
changes and incentives. Federal Reserve staff write that "such incentives
generate a run as a self-reinforcing prophecy".[^fed-stable] Clements
argues that algorithmic stablecoins are "inherently
fragile".[^clements] Beanstalk says it "uses credit instead of
collateral".[^bean-docs]

### Stablecoin-backed and wrapped

Some tokens are backed by other stablecoins. USDai is
collateralised by PYUSD, Polymarket's pUSD and Avant's avUSD by USDC, and
Saturn's USDat by a PYUSD wrapper.[^usdai-docs][^polymarket-docs][^avant-docs][^saturn-docs]

## How pegs are maintained

Issuers mint and burn directly in a primary market, usually with a
limited set of customers, while everyone else trades in secondary
markets. Federal Reserve staff write that "secondary markets actually
price the assets and help enable a stablecoin to maintain its dollar
peg". Dai differs in that any Ethereum user can mint it by depositing
collateral.[^fed-primary]

Lyons and Viswanath-Natraj treat a peg like a fixed exchange rate. They
find that arbitrage keeps Tether near its peg and that issuance plays a
limited role, with stabilisation mainly coming from the demand
side.[^lyons] Ma, Zeng, and Zhang find that arbitrage is concentrated,
reporting that Tether "only allows 6 agents in an average month to
redeem stablecoins for cash". They argue that efficient arbitrage helps
price stability but raises run risk.[^ma] Federal Reserve staff wrote in
April 2026 that stablecoins with safer, more liquid reserves have lower
run risk and have seen relatively stronger adoption.[^fed-2025]

## Uses and effects

The International Monetary Fund attributes most recent growth to crypto
trading, and says future demand could come from payments and
tokenisation.[^imf] Visa said in April 2026 that its stablecoin
settlement pilot had reached an annualised US$7 billion.[^coindesk-visa]

Stablecoin reserves have become large enough to affect government debt
markets. A BIS working paper finds that inflows lower three-month
Treasury bill yields, with larger effects during market
stress.[^bis-1270] Another finds that stablecoin flows appear largely
unaffected by capital flow restrictions.[^bis-1370]

## Risks and criticism

- Runs. Hyun Song Shin of the BIS warns of fire sales of backing assets
  and says stablecoins lack the settlement function of central bank
  money.[^reuters-bis]
- Dollarisation. BIS staff write that "digital dollarisation poses acute
  risks to monetary sovereignty" in emerging markets, and the IMF says
  stablecoins may contribute to currency substitution where confidence
  in domestic money is low.[^bis-170][^imf]
- Illicit finance. Chainalysis, as reported by The Block, attributed 84%
  of illicit crypto transaction volume in 2025 to stablecoins, in what it
  called a lower-bound estimate.[^block-chainalysis] The Financial Action
  Task Force described them in March 2026 as a relatively stable medium
  for moving proceeds.[^fatf] A UN report named USDT in Southeast Asia;
  Tether said it was disappointed and that its tokens can be traced on
  public blockchains.[^block-un]
- Central control. Issuers of reserve-backed coins can freeze tokens, and
  the GENIUS Act requires the ability to block, freeze, and reject
  transactions.[^genius] The dispute over when an issuer should use that
  power is covered in [USDC](usdc.md#incidents-and-controversies).
- Stacked exposure. Federal Reserve staff identify complex intermediation
  chains and vertical integration as vulnerabilities.[^fed-2025]

## Regulation

### United States

The GENIUS Act, signed on 18 July 2025, takes effect on the earlier of 18
months after enactment or 120 days after regulators issue final rules.
It requires reserves of at least one to one in assets such as dollars,
insured deposits, and Treasuries with 93 days or less to maturity. It
requires monthly disclosure and bars issuers from paying interest or
yield to holders. From three years after enactment, service providers may
not offer US persons a stablecoin from an issuer that is not
permitted.[^genius]

The Office of the Comptroller of the Currency (OCC) issued a final rule
under the Act on 21 October 2026, effective 18 January 2027. WilmerHale
describes it as the first from a federal banking agency.[^wilmerhale] Whether intermediaries can pay rewards on stablecoins
remains disputed. A May 2026 text of the CLARITY Act barred yield
equivalent to bank interest but kept rewards tied to activity, and the
bill failed to clear the Senate's 60-vote threshold on 15 September
2026.[^coindesk-yield][^coindesk-clarity] New York set its own rules
earlier, in guidance issued on 8 June 2022.[^nydfs-2022]

### European Union

MiCA's titles on asset-referenced and e-money tokens have applied since
30 June 2024.[^mica-149] Tether ended its euro token that year, citing
regulation and falling demand.[^block-eurt] European officials are
divided. Christine Lagarde, president of the European Central Bank, said
on 8 May 2026 that "the case for promoting euro-denominated stablecoins
is far weaker than it appears", a position opposed to that of Bundesbank
president Joachim Nagel, who backed them.[^block-lagarde] Qivalis, a
group of 37 European banks, received an e-money authorisation from De
Nederlandsche Bank on 14 October 2026.[^qivalis-dnb]

### United Kingdom

The Bank of England published its approach to sterling systemic
stablecoins on 22 June 2026, replacing holding limits with a temporary
issuance guardrail.[^boe] The Financial Conduct Authority published
final rules on 30 June 2026, and KPMG reports they take effect from
October 2027.[^skadden-fca][^kpmg-uk]

### Asia

- Hong Kong. The Stablecoins Ordinance took effect on 1 August
  2025.[^hkma] The Hong Kong Monetary Authority issued its first licences
  on 10 April 2026, to HSBC and Anchorpoint Financial, a venture of
  Standard Chartered, HKT, and Animoca
  Brands.[^charltons][^hsbc-licence] Anchorpoint began rolling out HKDAP in
  August 2026, and Decrypt reported that HSBC's RedCoin went live in
  October.[^block-hkdap][^decrypt-redcoin]
- Singapore. The Monetary Authority of Singapore finalised a framework
  for single-currency stablecoins on 15 August 2023, requiring par
  redemption within five business days.[^mas]
- Japan. Amendments to the Payment Services Act were enacted on 3 June
  2022.[^iflr] JPYC launched under this regime on 27 October
  2025.[^block-jpyc]
- South Korea. A Digital Asset Basic Act was proposed in April 2026. The
  Bank of Korea argued that only banks holding 51% of an issuer should be
  able to issue stablecoins.[^coindesk-korea]

### International

The Financial Stability Board published recommendations for global
stablecoin arrangements on 17 July 2023.[^fsb-2023] Its review of October
2025 found that their regulation "is lagging".[^fsb-2025]
