Payment stablecoin

A payment stablecoin is a digital asset issued for payments and settlement, redeemable on demand at a fixed value, typically one US dollar, and backed one-to-one by reserves. The term became a formal US legal category with the GENIUS Act of July 2025, by which time total stablecoin supply had grown beyond $230 billion.

Why it matters

Payment stablecoins move dollar value on blockchain rails around the clock, settling in minutes across borders where correspondent banking takes days. Under the GENIUS framework, permitted issuers must hold reserves in cash and short-term Treasuries, publish monthly attestations, and may not pay interest to holders, a design that makes each token a full-reserve digital claim on the dollar rather than a fractional bank deposit.

Their reserve mechanics link crypto to sovereign debt markets. Issuers collectively rank among the larger holders of US Treasury bills, so stablecoin adoption abroad functions as distributed demand for US government debt.

In the gold vs bitcoin debate

Payment stablecoins sharpen the gold vs bitcoin question by splitting money's functions. They dominate the medium-of-exchange role in crypto markets, leaving gold and bitcoin to compete purely as stores of value. Hard-money advocates note the irony that the most used blockchain asset is a tokenized fiat liability, exactly the instrument gold and bitcoin were meant to transcend.
