Panel: Stablecoins promise faster cross-border flows but hinge on rails, governance and UX

A panel of industry executives and a moderator discussed how stablecoins could transform payments and treasury functions while highlighting the operational and policy work still required for broad adoption.

Panelists said the most immediate, high-value use case is cross-border transfers that reduce FX risk and settlement delays. Tim Spence, chairman and CEO of Fifth Third, said his clients face large cross-border frictions and argued the market needs industry-standard governance and widely accepted rails rather than hundreds of isolated coins: "Our focus has been on looking at the solutions that are in the market, finding ways ... to provide them to utilize things that can become industry standards."

Issuers and fintechs emphasized consumer and enterprise demand. Fernando Perez, cofounder and CEO of Dollar App, said his company serves more than 1,000,000 users across Mexico, Argentina, Colombia and Brazil and that use cases include dollarization of savings, travel spending and cross-border payroll. He said Dollar App partners with locally regulated entities and card networks to provide fiat on/off-ramps and abstract complexity for end users.

Heath Tarbert, president of Circle, argued that trust and clear rules are foundational: "All stablecoins aren't equal and all stablecoins aren't stable," and he said the recently referenced "Genius Act" will raise transparency and standards when implemented. Tarbert also highlighted programmability for trade finance and treasury, describing Circle's work on an enterprise-grade chain with subsecond deterministic finality to support contract-linked payments.

Panelists repeatedly flagged two broad bottlenecks: (1) trust, compliance and transparent reserves; and (2) utility—liquidity and the ability to move easily between fiat and stablecoins. Chad Cascarella, CEO of Paxos, emphasized the difficulty of re-converting stablecoins into fiat at certain hours and across jurisdictions and said the market will likely concentrate around a handful of broadly accepted rails while many specialized tokens will persist for co-branded or closed ecosystems.

Where blockchain programmability offers clear value—such as automating payment release on receipt of goods—panelists argued it can significantly speed workflows. But several speakers warned that to change entrenched behavior, programmability must demonstrably outperform existing systems and integrate with procurement and treasury back ends.

The conversation closed with short-term forecasts: expect more bank-initiated 24/7 transfers, greater use of tokenized collateral, and continued work on orchestration layers that marry fiat liquidity at the rails' ends with stablecoin rails between jurisdictions. The panel also discussed policy and supervisory implications for tokenized deposits and emphasized banks will continue to play a role in lending and maturity transformation even as stablecoins become a payment alternative.
