Korea Plans Won Accounts at Foreign Banks Under New Roadmap

An American walking into a bank in New York would, under a plan announced by Korea’s Ministry of Economy and Finance, be able to open an account denominated in Korean won and then settle transactions in that currency with another non-resident — without either party touching Korea’s onshore banking system. That single scenario is the clearest expression of what the ministry’s newly released won internationalization roadmap is trying to achieve: turning a currency that has spent decades ring-fenced by capital controls into one that circulates and clears abroad on its own.

The Restriction Being Dismantled

The won has long occupied an unusual position for a currency issued by a major manufacturing and export economy. Trade invoicing, portfolio flows and foreign direct investment involving Korea run at the scale of a top-tier economy, yet the currency itself has been treated as a domestic instrument. Non-residents have generally needed to route won transactions through Korean banks or through designated onshore channels, and offshore transfers between foreign parties have been constrained rather than freely permitted. The practical consequence is that global institutions hedge Korea exposure using non-deliverable instruments and dollar legs rather than holding and moving won directly.

The roadmap targets exactly that gap. Allowing foreign residents to hold won balances at their own domestic banks, and to transfer those balances to other foreign residents, creates the beginnings of an offshore won pool — the same structural feature that underpins offshore markets in other regional currencies.

From Regulated to Freely Exchangeable

The government has framed the objective in categorical terms: moving the won out of the “regulated currency” bucket and into the group of freely exchangeable currencies. That is a classification with real-world consequences. Index providers, custodian banks and global asset managers apply convertibility and settlement-access tests when deciding how to treat a market, and friction in currency access has historically been cited as a drag on Korea’s standing in those assessments.

Two workstreams sit behind the goal. The first is infrastructure — the account structures, correspondent banking arrangements and settlement plumbing that let won move between offshore parties without a Korean intermediary at every step. The second is regulatory: rewriting the rules that currently define who may hold won, where, and for what purpose. The ministry has also convened a dedicated task force on won internationalization, signaling that implementation is being handled as a continuing program rather than a single legislative act.

Demand Is the Harder Half

Permission to hold a currency is not the same as wanting to. The roadmap explicitly pairs deregulation with measures to expand demand for the won, and that pairing is the more difficult engineering problem. An offshore currency market needs reasons for foreigners to accumulate balances — invoicing of trade in won, won-denominated bonds issued to international buyers, deep and liquid hedging instruments, and interest-bearing places to park idle balances. Without those, offshore accounts sit empty and the reform delivers optionality rather than volume.

What Opening Up Costs

Greater convertibility also means giving up a measure of insulation. Korea’s capital-flow controls were tightened in the aftermath of the 1997 and 2008 crises precisely because the economy proved vulnerable to abrupt reversals in foreign funding. An offshore won market that policymakers cannot directly observe or intervene in adds a channel through which pressure on the currency can build outside domestic hours and outside domestic reach. That trade-off — credibility and access in exchange for reduced control — is the central judgment embedded in the roadmap, and it explains why the shift is being staged over time rather than switched on at once.

The detail that will matter most in the coming phase is sequencing: which account types, which counterparties and which jurisdictions come first, and what reporting obligations attach to offshore won balances.
