Korea's Won Internationalization Plan: What a 3.4% Number Reveals

Thirty years after the Asian financial crisis locked down the won, Seoul says it's ready to let go — but the numbers show just how far there is to go.

What happened

Korea's finance ministry, financial regulators, the Bank of Korea, and the securities depository jointly announced a "won internationalization roadmap" on July 19. The goal is to make the won a "freely convertible currency" — one foreigners can raise and trade offshore without restriction. The domestic foreign exchange market already switched to 24-hour operation on July 6, and the Bank of Korea plans a pilot run of a round-the-clock offshore won settlement network starting in September, with full launch targeted for 2027. A new registration system for "offshore won settlement institutions" will also let foreign banks hold, remit, and settle won on behalf of clients without those clients needing a Korean bank account.

Why it matters

This roadmap touches the foundation of Korea's foreign exchange policy for the first time in 30 years, since the 1997 Asian financial crisis. That crisis pushed the government to lock the won into a tightly "restricted currency" — foreigners were kept from using it freely offshore, to head off destabilizing capital swings. But a run of favorable conditions — a semiconductor export boom, record tax revenue, and the shift to 24-hour FX trading — convinced officials that Korea can now "handle" internationalization. In an economy with ever more cross-border trade and investment flows, the core aim is to let firms transact directly in won, without the cost of converting to dollars or hedging currency risk.

By the numbers

The gap between ambition and reality shows up directly in trade data. Won-denominated export settlements hit a record 3.4% of Korea's total in 2025 — yet the dollar still accounts for 84.2%. Imports look similar: 6.6% in won versus 79.3% in dollars. If even Korean companies overwhelmingly prefer the dollar to their own currency, getting foreigners to use the won is a taller order still. China's yuan is the closest precedent: Beijing has pushed yuan internationalization as national strategy since 2009, yet by 2020 the yuan's share of global payments was just 1.6%. If it took the world's second-largest economy more than 15 years to get only that far, Korea's ambitions face a long road.

The debate

The government and related institutions argue that once 24-hour FX trading and offshore settlement infrastructure are in place, corporate hedging costs will fall and capital markets will mature. The classic counterargument to currency internationalization is capital-flight risk — once the won trades freely offshore, external shocks could transmit into Korea's financial markets faster. But the Korea Capital Market Institute, among others, argued in a recent report that such concerns are "increasingly losing their force," countering that internationalization can actually serve as a crisis buffer. The government's roadmap reflects an awareness of that trade-off, pairing faster liberalization with risk-management steps like expanded currency swap lines and stronger FX market stabilization capacity — speed, but with a safety net attached.

What's next

September's pilot of the offshore won settlement network is the first real test. How many foreign institutions actually join, and how much trading volume materializes, will likely determine whether the full 2027 launch succeeds. For exporters and importers, policy-finance incentives tied to won-denominated trade settlement will force a concrete cost-benefit calculation on currency conversion and hedging. For investors, rising offshore demand for won-denominated assets could ease exchange-rate volatility over time — but more frequent foreign capital in and out could just as easily make short-term swings sharper. In the end, the roadmap's success will hinge less on how much regulation Seoul lifts now, and more on whether it can hold that opening in place the next time a crisis tests it.
