Stablecoins: What They Are and How They Work
Stablecoins are blockchain‑based tokens pegged to the U.S. dollar through a 1:1 reserve of cash and short‑term Treasury notes, offering near‑instant, low‑cost transfers. They aim to solve cross‑border payment delays, high fees, and dollar‑access challenges in inflation‑hit economies. The market is led by Tether, with roughly $190 billion in circulation, while Circle’s USDC provides greater regulatory transparency. Issuers generate revenue primarily from interest on reserve assets rather than user fees, positioning stablecoins as a potential new source of demand for U.S. Treasury debt.
