The Bank of Korea has launched its first 24-hour won settlement network pilot, letting foreign investors settle Korean currency transactions outside the country’s conventional banking hours. The trial, announced Sep. 21, began Monday at 9 a.m. with the country’s four largest banks — and the first test transaction, worth roughly 1.4 billion won (about 1 million USD), cleared about half an hour later.

The Hook: Central Bank Money That No Longer Sleeps
The Bank of Korea Won International Wire Network began trial operations on Monday with KB Kookmin Bank, Woori Bank, Hana Bank and Shinhan Bank participating. Full operation is scheduled for January 2027, when foreign banks are expected to join after roughly three months of testing. The system runs continuously from 9 a.m. on one business day until 9 a.m. the next, closing only on weekends and public holidays.
Why does this matter to a crypto investor? Because settlement hours are one of the last big frictions between traditional finance and 24/7 digital-asset markets. Crypto never closes, but the money rails underneath it traditionally do. A central bank building around-the-clock settlement infrastructure — even one that does not itself use blockchain — is a direct response to the always-on world crypto created. Bloomberg reported the launch as laying the groundwork for greater foreign access to local markets.
On-Chain Evidence: How the RFI-K Model Works
The mechanics are straightforward once you strip the acronyms. Foreign investors can settle won through accounts held with Registered Foreign Institutions for KRW Business — RFI-Ks — without opening a separate account at a Korean bank. An overseas investor holds or transacts won through a registered institution in its home market, and the underlying settlement is completed through the central-bank infrastructure.
- Revised foreign-exchange rules, published days before the pilot, allow registered foreign institutions to open omnibus accounts at Korean foreign-exchange banks — think of an omnibus account as one big shared bucket a foreign bank holds in Korea on behalf of all its clients.
- First test transaction: approximately 1.4 billion won, equivalent to roughly 1 million USD, executed around 9:30 a.m. Monday between two participating domestic institutions, as reported by SBS.
- Policy backing: the changes form part of the government’s plan to make offshore won transactions less dependent on time and location, according to the Finance Ministry.
The Core Conflict: Two Parallel Tracks to Tokenized Money
Here is where it gets interesting for DeFi watchers. The new international wire network does not use the same structure as the Bank of Korea’s blockchain-based projects. The central bank has been developing separate tokenized settlement infrastructure through Project Hangang and the Bank for International Settlements-coordinated Project Agora, which continue testing tokenized reserves, deposits and cross-border settlement on their own timelines.
In other words, Korea is running two experiments at once: a conventional central-bank rail extended to 24 hours for institutional convenience, and a blockchain-native track for tokenized central-bank money and deposits. The two are complementary rather than competing — the wire network solves access and hours today, while the tokenized projects build the programmable foundation for tomorrow. The BOK said “the network is expected to improve foreigners’ access to won settlement infrastructure, eventually enhancing the currency’s international standing,” a policy expectation rather than a measured pilot outcome.
Market Implications: Why a 1 Million USD Test Transaction Matters
A 1 million USD first transaction is a rounding error in Korea’s foreign-exchange market, but the direction is the story. Korea has already moved its domestic FX market toward 24-hour trading; this network adds the payment side. The full plan — the Won Internationalization Roadmap published in July by the Finance Ministry, the Bank of Korea and other agencies — calls for round-the-clock foreign-exchange access, offshore won accounts, easier capital transactions, and settlement infrastructure available outside Korea.
For crypto markets, the relevance is competitive as much as technical. Much of the offshore won and offshore currency settlement that stablecoins and exchange networks currently capture is exactly the flow Korea wants running through regulated central-bank rails. The roadmap even includes liquidity backstops: domestic banks can provide temporary won funding when overseas institutions face shortages, and the government and central bank may add liquidity when necessary — features that decentralized alternatives cannot offer. The broader digital-asset backdrop remains constructive, with Bitcoin trading near 86,949 USD and Ethereum near 2,782 USD at the time of writing, keeping pressure on legacy systems to modernize.
The Verdict: Access First, Tokenization Next
Should you care about a Korean central-bank wire network? If you hold crypto, yes — indirectly. Every major economy that builds 24/7, border-friendly settlement is narrowing the practical gap that made stablecoins indispensable for cross-border movement. Korea is not banning or replacing crypto rails; it is competing for the same settlement flows with an improved state alternative, while separately experimenting with tokenization through Projects Hangang and Agora. For DeFi, that means the next cycle’s competition is not just against slow legacy banking — it is against fast, modernized central-bank infrastructure. The projects that survive will be the ones doing what central banks still cannot: programmable, permissionless, global from day one.

RFI-K is the sleeper detail here. Foreign funds settling won without opening accounts at KB or Shinhan changes the custody math for KOSPI flows way more than a 30 minute first tx does
first transaction was 1.4 billion won, about a million bucks, and it cleared in half an hour. usdc does that in 30 seconds, just saying
missing the point tho, usdc settles on dollar rails outside korea. this keeps every step inside BOK supervision, that half hour is compliance work, not latency
the point is it’s central bank money, not a stablecoin. a BOK rail running 9am to 9am opens institutional flows into KOSPI and eventually korean crypto venues
and once foreign desks get comfortable with 24h won the offshore NDF market loses its grip on after hours korea exposure. that is the quiet big deal in this pilot
NDF desks wont give that spread up without a fight. expect the lobbying to get loud between now and the january full launch
NDF desks already lost this argument, the lobbying just sets the transition fee. january full launch is the date that actually matters
NDF desks setting the transition fee is the right framing. the rail exists now, the only question left is who pays to unwind the old spread
exactly, and weekends closed is the tell. crypto rails are still the only ones live sunday night when tokyo starts dumping
fair dunk, but closing weekends is deliberate. they want faster settlement, not a market running while the supervisors sleep
usdc does it in 30 seconds until the dollar side hits a US bank at 3am. the won leg was always the slow half of the pair
KB, Shinhan, Woori and Hana all live on day one. whatever else you say about the pace, the BOK got the hard part done, everyone showed up
RFI-K means foreign funds can settle won without opening an account at KB or Shinhan at all. removing that friction is bigger for won liquidity than ppl realize
RFI-K cuts the other way too. treasurers stop parking collateral at KB or Shinhan just to hold won overnight, so the domestic banks are the ones quietly losing the hostage business here
the hostage business point is underrated. domestic banks losing the overnight parking grip is the quiet structural change here, nobody lobbies against that politely
Worked compliance at a Korean brokerage for years and the 9 to 4 settlement window was always the bottleneck for foreign clients. This has been requested since like 2019.
former brokerage ops here too. the 3pm fx cutoff created so many failed settlement chains. half hour on 1.4 billion won is slow, but it ran after close and that is the whole ballgame
^ exactly. everyone obsessing over the tokenized deposit pilot but extending hours on the boring old rail fixes the real pain point first
^ this. the tokenized deposit pilot gets the headlines but a 24h wholesale rail is what foreign desks have been begging the BOK for since 2019
a 1.4 billion won first transaction on day one of a pilot is not nothing. most CBDC trials settle test payments between the same three state owned banks and call it progress
first tx cleared in 30 min and it was only 1.4b won. small numbers but the rails actually work, thats the part people sleep on
foreign banks joining in early 2027 is when this gets interesting. four domestic banks moving 1 million dollars is a demo, a global custodian settling through it is the product
custodian onboarding is where those three months of testing earn their keep. swift message compatibility is the unglamorous bit that decides whether this scales past the four banks
Full operation in January 2027, foreign banks after three months of testing. Slow by crypto standards but honestly realistic for the BOK.
1.4 billion won first transaction and all four banks live on day one. most pilot launches fumble the coordination part, BOK got the boring thing right
