Stablecoins are moving beyond crypto trading into the infrastructure that powers payments, treasury operations, collateral, savings, and cross-border finance, and Circle CEO Jeremy Allaire says digital dollars now show product-market fit across several financial activities.

Speaking during Circle's Aug. 19 earnings AMA, Allaire described a shift in which stablecoins extend from digital asset markets into mainstream financial operations.

That shift is unfolding against a clearer U.S. regulatory backdrop: the GENIUS Act, signed into law in July 2025, created the first federal framework for payment stablecoins, imposing reserve, redemption, and disclosure requirements on licensed issuers.

From Crypto Market Plumbing to Real-World Finance

In digital asset markets, stablecoins already function as cash, collateral, and settlement assets across platforms operating around the clock. Their role is now expanding as large companies increasingly use digital dollars for treasury management, internal transfers, and working capital.

Allaire also pointed to rising demand across emerging and global markets, where households and businesses use digital dollars as savings instruments. For some users, those assets provide an alternative to traditional dollar bank accounts while supporting commerce, investment, and international payments.

Tokenization is widening that reach further as equities, commodities, and other traditional assets begin moving onto blockchain-based trading infrastructure.

Cross-Border Settlement Emerges as a Core Use Case

Against that backdrop, cross-border payments are becoming one of the clearest areas where stablecoins are entering mainstream financial operations. Allaire said financial institutions can use digital dollars as the settlement leg between counterparties, reducing reliance on conventional banking settlement windows. Recipients can also retain the stable asset instead of converting immediately into local currency, adding another use case beyond simple transfers.

Circle Payments Network reflects that shift. The network reached $14.7 billion in annualized transaction volume based on trailing 30-day activity at quarter-end, a figure that increased 76% quarter over quarter, while enrolled financial institutions rose 29% to 175. Nium has also connected the network with payout infrastructure covering more than 190 countries and 100 currencies.

The wider payments sector is developing similar infrastructure. Visa said its stablecoin settlement pilot reached a $7 billion annualized run rate after expanding support to nine blockchains. Visa had already introduced USDC settlement for participating U.S. issuers and acquirers, giving institutions access to seven-day settlement.

That expansion addresses a costly gap in traditional remittances. World Bank data showed the average cost of sending $200 globally stood at 6.36%, more than twice the United Nations' 3% target. Lowering such costs is also a formal policy objective under the G20's cross-border payments roadmap, which set cost, speed, and access targets for the end of 2027.

USDC Growth Deepens Circle's Institutional Finance Reach

Beyond payments, Circle's operating figures show how quickly its role across broader financial infrastructure has expanded. USDC circulation reached $73.3 billion at the end of the second quarter, representing 19% year-over-year growth, and the token remains the second-largest stablecoin by circulation behind Tether's USDT. At the same time, quarterly on-chain transaction volume climbed 151% to $14.8 trillion, while Circle generated $701 million in revenue and reserve income.

Alongside that growth, institutional adoption widened, extending USDC's presence across traditional financial services. BNY added direct USDC minting and redemption to its digital asset custody platform, while Standard Chartered launched integrated USDC access. Marex completed a stablecoin-powered initial-margin transaction in regulated derivatives clearing, allowing USDC to operate as collateral within traditional markets. The moves run alongside broader bank experimentation with tokenized dollars, including JPMorgan piloting its JPMD deposit token on public blockchains.

Allaire also identified AI agents and retail merchant payments as emerging channels for further usage. Circle's Agent Stack now includes more than 900 paid services, while 99.3% of x402 agent-payment volume settles in USDC.

The company is also preparing Arc, its stablecoin-focused blockchain, for a Sept. 16 mainnet launch with more than 100 institutional and ecosystem builders.

Taken together, the data shows stablecoins moving from crypto market plumbing toward broader payment and settlement rails used across global finance, with the Arc mainnet launch and the continued rollout of bank and card-network settlement programs marking the near-term milestones to watch.
