Global trade still relies on outdated correspondent banking networks, pre-funded Nostro/Vostro accounts, and time-zone mismatches that cause multiday delays. Industry leader John Cho advocates for a multi-currency stablecoin ecosystem where local currency stablecoins complement USD stablecoins to prevent double foreign exchange conversions.

Correspondent banking networks, pre-funded Nostro and Vostro accounts, and structural time-zone mismatches impose a heavy toll on global trade. The model forces enterprises to contend with multiday settlement delays, restrictive banking hours, and significant foreign-exchange slippage.
Across Southeast and East Asia, enterprises pay suppliers in South Korean won, settle regional invoices in Singapore dollars, and fund operations in domestic currencies. Routing these transactions through U.S. dollar intermediaries adds unnecessary foreign-exchange overhead and exposes businesses to volatile currency swings. Consequently, some industry participants see multi-currency stablecoin orchestration as the solution.
Leading the push toward multi-currency stablecoin orchestration is John Cho, CEO and co-founder of Ratio and chief stablecoin officer at the Kaia DLT Foundation. Positioned at the intersection of institutional FX and Web3 strategy, Cho utilizes Ratio’s chain-agnostic settlement rails and Kaia’s unified Layer 1 network—created through the merger of Kakao’s Klaytn and LINE’s Finschia—to eliminate regional cross-border friction.
Rather than viewing localized Asian stablecoins as adversaries to U.S. dollar dominance, industry leaders see a complementary architecture emerging. The dollar will likely retain its role as the primary global reserve currency, but regional trade requires a more nuanced approach.
“I don’t think this is an either-or scenario,” Cho says. “USD stablecoins will continue to dominate global liquidity because the dollar remains the world’s reserve currency, but real commerce happens in local currencies. What we’re seeing is the emergence of a multi-currency stablecoin ecosystem. Local currency stablecoins complement USDT and USDC by eliminating unnecessary FX conversions and enabling domestic settlement.”
The goal, Cho notes, is not to displace existing liquidity pools, but to engineer infrastructure that allows multi-currency digital assets to interoperate seamlessly across borders.
A core source of legacy banking friction is the requirement for financial institutions to maintain pre-funded Nostro and Vostro accounts around the world. These locked reserves consume massive amounts of working capital while offering little flexibility during off-market hours or weekend liquidity dry spells.
On-chain FX orchestration layers offer a fundamental alternative by acting as regulated middleware. Operating 24/7 outside traditional banking windows, platforms such as Ratio leverage proprietary on-chain liquidity within permissioned environments to ensure continuous settlement. By sourcing liquidity in partnership with local issuers and market makers, multi-route rebalancing flows can coordinate between internal reserves and issuer minting pathways—enabling instant execution even when traditional fiat ramps are closed.
Rather than requiring institutions to overhaul their technology stacks overnight, orchestration layers plug directly into existing ERP systems and treasury workflows. Acting as an invisible routing engine behind traditional payment gateways, enterprises can execute on-chain settlement selectively—gradually shifting volume onto digital rails where measurable improvements in speed, cost, and slippage reduction can be demonstrated.
The catalyst needed to unlock institutional capital at scale is regulatory clarity. For years, uncertainty around compliance controls and legal definitions kept traditional enterprises on the sidelines, forcing conservative treasurers to operate under threat of “regulation by enforcement.”
“Large-scale adoption will only happen when stablecoin infrastructure demonstrably outperforms existing rails without requiring companies to compromise on compliance,” Cho says. “We are seeing this regulatory tipping point unfold rapidly in Asia, where we expect every major country to pass some form of stablecoin legislation into law over the next 12 to 24 months.”
