Stablecoin Settlement Brings Cross-Border Interoperability to Local RTP Networks

Consumers in Brazil can transfer money in seconds using Pix, while businesses in India settle transactions instantly through UPI, and Europe’s SEPA Instant and Singapore’s PayNow have dramatically compressed settlement times inside their own respective bounded networks.

But the key word here is bounded. Once money crosses borders, the settlement process often slows to a crawl. That same consumer in Brazil, after all, can’t pay that business in India using Pix or UPI with nearly the same speed as they can in-network.

Or can they? A new architectural model of cross-border settlement is beginning to emerge, and it’s being powered by stablecoins. Instead of trying to replace domestic payment systems, stablecoins are increasingly being inserted between them.

This week (May 4), for example, Tetra Digital Group launched a payment stablecoin designed to streamline cross-border settlement.

In this model, stablecoins handle the cross-border jump while and local instant-payment rails handle the last mile. Funds move out of a domestic bank account or wallet onto a blockchain-based stablecoin network, traverse borders nearly instantly, and then off-ramp into another local payment system, which can often be faster and cheaper than traditional approaches based on correspondent banking networks.

The key innovation is not the stablecoin itself. Fiat-linked digital assets have existed for years. What has changed is the surrounding infrastructure, and it’s poised to turn stablecoins into a key unlock for cross-border operations across FX, payouts, payroll, remittances, merchant settlement, and B2B treasury by enabling a new settlement layer that sits invisibly between two local payment networks.

Still, not every country is on board. Brazil over the weekend (May 3) banned electronic foreign exchange (eFX) companies from using cryptocurrencies to settle overseas remittances.

Unlocking the Missing Settlement Layer in Global Payments

Cross-border payments remain a multi-trillion-dollar inefficiency embedded inside global commerce, weighed down by correspondent banking chains, pre-funded accounts, foreign exchange friction, compliance overhead and opaque fees.

Stablecoins can offer a way to compress both settlement time and capital requirements simultaneously. The crypto-native term for a cross-border stablecoin settlement is a “bridge,” or a “stablecoin sandwich.”

The opportunity is especially pronounced in emerging markets where access to dollar liquidity remains uneven. In countries with volatile currencies or constrained banking infrastructure, stablecoin-linked payment systems provide businesses with a more stable medium for cross-border commerce while preserving compatibility with local payment networks.

But the degree of innovation that stablecoins offer doesn’t come without its own new and native risks. Hacks on digital asset bridge solutions represent nearly 40% of the entire value of crypto lost due to hacks across the entire digital asset sector’s history. Counterparty risk is a prominent concern.

“CFOs are, rightly so, conservative,”  Tanner Taddeo, CEO of Stable Sea, told PYMNTS during a recent conversation for the  From the Block podcast. “They’re not buying innovation. They’re buying to de-risk something … It’s a crawl, walk, run approach to the enterprise because that trust does take time. It’s never given, it’s always earned.”

Findings in the March PYMNTS Intelligence report, “Stablecoins Gain Ground: Why CFOs See More Promise There Than in Crypto,” reveal that while more than 4 in 10 (42%) middle market companies have at least discussed stablecoins, only 13% have reported actual stablecoin use.

Building Toward an Invisible Cross-Border Future

The competition surrounding stablecoin-powered payments is no longer simply banks versus crypto firms. It is increasingly a contest over who controls orchestration.

Banks retain regulatory trust, customer relationships, and deep liquidity access. Card networks possess global merchant acceptance and decades of settlement expertise. Crypto-native firms move faster technologically and often operate with lower infrastructure costs.

Each player is attempting to occupy the middleware layer connecting local real-time payment systems globally.

Visa, for example, in March announced it was extending its partnership with Stripe-owned stablecoin infrastructure platform Bridge to bring stablecoin cards to over 100 countries.

But if stablecoins are becoming infrastructure, regulation is determining who gets to own that infrastructure.

Large enterprises will not route treasury operations through unstable legal frameworks. Banks will not integrate blockchain settlement rails without clarity around custody, reserves, and counterparty risk. As regulation matures, stablecoin markets may become less decentralized than early crypto advocates envisioned and more institutionally concentrated.

Recent research by PYMNTS Intelligence shows that businesses that wish to use stablecoins are more interested in joining forces with banks than with crypto wallets.
