Stablecoins and Tokenization Emerge as New Market Plumbing

Stablecoin cards link on-chain balances such as USDT and USDC to established networks including Mastercard, converting digital dollars into fiat at checkout so merchants do not need crypto infrastructure or exposure to token volatility. The model tackles crypto’s “last mile” by preserving familiar card credentials, acceptance, chargebacks and consumer protections. Its significance lies less in replacing card networks than in turning fragmented stablecoin liquidity into a usable payment source across hundreds of millions of merchant locations.

On May 8, 2026, Rain head of strategic partnerships John Timoney told a Consensus Miami panel that retail spending on stablecoin cards had risen about 105% to 106% over the prior year and could reach double-digit shares in some Latin American markets. Rain, now a Mastercard Principal Member, is exploring regulated-stablecoin settlement with the network. Timoney said weekend and holiday settlement had reduced trapped capital by more than 40% in some programs. The segment remains nascent: Consensys executive Ray Hernandez estimated stablecoin cards account for less than 1% of global card spending.

Stablecoin issuers increasingly resemble narrow banks: they take in dollars, issue redeemable tokens and invest reserves in short-dated Treasuries and money-market instruments, retaining much of the yield. Tokenized money-market funds extend that model by putting regulated cash products on blockchains, where they can serve as reserves, collateral and settlement assets. The shift matters because crypto’s next profit pool may depend less on speculative tokens than on familiar financial plumbing, compliance and government-debt income.

BlackRock on Aug. 3, 2026, launched two tokenized money-market offerings. BSTBL puts shares of an existing fund, valued at about $6.1 billion in May, on Ethereum, while BRSRV targets stablecoin reserve management across multiple blockchains. Tether’s figures underscore the economics: as of March 31, its US Treasury exposure stood at $141 billion, first-quarter net profit reached $1.04 billion and excess reserves climbed to a record $8.23 billion.

The launch of open-standard stablecoin OUSD has pitted advocates of open finance against traditional banks’ deposit-token settlement networks. The development signals an era of free competition in money and challenges the model in which a single issuer monopolizes returns from U.S. Treasury reserves. Unlike Libra, which challenged central banks’ authority to issue money, OUSD is pursuing a regulated U.S. dollar model governed by more than 100 institutions. It has formally opened a cutthroat battle between established and emerging financial players for control of cross-border settlement.

On June 30, 2026, the Open Standard alliance, comprising more than 140 major companies including Visa, Mastercard and BlackRock, announced the launch of OUSD. The project offers shared returns from U.S. Treasury reserves and charges no fees. Rival Circle’s shares plunged 16% that day, while Bridge founder Zach Abrams was named interim CEO.

Stablecoins are issued by companies such as Tether and Circle and are typically backed by reserves of U.S. dollar cash or short-term U.S. Treasury securities, with the aim of maintaining a value of $1 per token. Unlike Bitcoin, which has a fixed supply and a floating price, stablecoins can serve as a lower-volatility medium for trade settlement, cross-border payments and on-chain finance.

TerraUSD lost its $1 peg in May 2022 and collapsed alongside LUNA, rapidly wiping out about $40 billion in market value and underscoring algorithmic and liquidity risks. The GENIUS Act was signed into law in the United States on July 18, 2025, requiring payment stablecoins to be backed 1:1 by eligible assets and establishing a regulatory framework for commercial use.
