Ratio CEO Says Multi-Currency Stablecoins Could Eliminate Costly FX Conversions Across Asia
Global trade still relies on outdated correspondent banking networks, pre-funded Nostro/Vostro accounts, and time-zone mismatches that cause multiday delays. In Asia, these legacy inefficiencies amount to a multibillion-dollar tax on working capital. While USD stablecoins like USDT and USDC have demonstrated proof of concept for digital asset settlement, they solve only part of the puzzle. Trade finance may run on dollars, but local commerce runs on local currencies like South Korean won, Singapore dollars, and others. Routing transactions through USD intermediaries adds unnecessary foreign-exchange overhead.
John Cho, CEO of Ratio and chief stablecoin officer at the Kaia DLT Foundation, advocates for a multi-currency stablecoin ecosystem. Rather than viewing localized Asian stablecoins as adversaries to USD dominance, Cho sees a complementary architecture. “USD stablecoins will continue to dominate global liquidity because the dollar remains the world’s reserve currency, but real commerce happens in local currencies,” he says. “Local currency stablecoins complement USDT and USDC by eliminating unnecessary FX conversions and enabling domestic settlement.”
A core source of friction is the requirement for financial institutions to maintain pre-funded Nostro and Vostro accounts, locking up massive capital. On-chain FX orchestration layers offer a fundamental alternative by acting as regulated middleware, operating 24/7 outside traditional banking windows. Platforms like Ratio leverage proprietary on-chain liquidity to ensure continuous settlement, even when traditional fiat ramps are closed.
To bridge the gap between legacy systems and modern infrastructure, Web3 providers are shifting toward pragmatic integration. Orchestration layers plug directly into existing ERP systems and treasury workflows, allowing enterprises to execute on-chain settlement selectively. The catalyst for institutional adoption is regulatory clarity. In the US, momentum around the CLARITY Act is bringing structural certainty. In Asia, Cho expects every major country to pass stablecoin legislation within 12 to 24 months.
“Large-scale adoption will only happen when stablecoin infrastructure demonstrably outperforms existing rails without requiring companies to compromise on compliance,” Cho says. As regulated stablecoins become integrated into national payment systems, the friction of converting between bank balances and block explorers will fade, positioning stablecoins as the invisible settlement layer for global commerce.
