Stablecoins 101

A plain-English foundation for finance leaders: what digital dollars are, how they stay pegged, and why they have become real settlement infrastructure.

FFiat-backed

Reserve-backed

Each token is backed 1:1 by cash and short-dated Treasuries held by a regulated issuer. USDC, USDT.

YYield-bearing

T-bill tokens

Tokenized money-market and Treasury funds that pass through yield. USDY, BUIDL.

CCrypto-backed

Over-collateralized

Backed by a surplus of on-chain crypto assets and governed by smart contracts. DAI / USDS.

SSynthetic

Delta-neutral

Maintain the peg using hedged derivative positions rather than fiat reserves. USDe.

What is a stablecoin?

A stablecoin is a digital token designed to hold a stable value, almost always one U.S. dollar. Unlike volatile crypto assets, a well-run stablecoin trades at or near $1.00 at all times, making it usable as a unit of account, a means of payment, and a store of short-term value.

The result is a dollar that moves like an email: instantly, globally, and 24/7, without a correspondent bank in the middle.

How do they hold the peg?

The dominant model is reserve-backed. For every token in circulation, the issuer holds one dollar of high-quality liquid assets, cash and short-dated Treasuries, and lets holders redeem at par. Arbitrage does the rest: if the token drifts below a dollar, traders buy it cheap and redeem for $1, pushing the price back up.

The credibility of a stablecoin is only as strong as the quality, transparency, and liquidity of its reserves.

The regulatory landscape

Regulation has shifted stablecoins from gray-area instruments to supervised financial products:

  • United States, GENIUS Act: a federal framework setting reserve, redemption, and disclosure standards for payment stablecoins.
  • European Union, MiCA: licensing and reserve rules for e-money tokens and asset-referenced tokens.
  • Asia & Middle East: Singapore, Hong Kong, and the UAE have issued or proposed dedicated stablecoin regimes.

Why CFOs should care

Stablecoins compress the cost and time of moving money. Cross-border payouts settle in seconds instead of days, weekend float disappears, and FX spreads narrow. With adjusted transfer volume now measured in the trillions, this is settlement infrastructure, not speculation.
