Korean Won Launches 24-Hour Trading from July 6, but MSCI Upgrade Remains in Limbo
N.R. Finch
South Korea will launch round-the-clock won-dollar trading on July 6, its biggest FX opening since the 1997 Asian financial crisis — yet MSCI this week kept Korea at "emerging market" status, pushing the upgrade question out another year.
What does 24-hour trading actually change?
Won-dollar trading expands from daytime-only hours to a continuous, round-the-clock session. Banks began trial runs this Monday.
This means → Korea is dismantling the FX control framework built after the 1997 crisis. Offshore investors can now trade the won in any time zone.
Three companion measures land at the same time: offshore investors may hold won directly, a new offshore won clearing system goes live, and an overdraft facility is introduced. In plain terms = foreign firms used to be limited to currency conversion; now they can hold and deploy won.
Why didn't MSCI buy in?
MSCI maintained Korea's "emerging market" classification in this week's annual review. The next review is one year away.
Two reasons cited: longstanding market-access barriers remain unresolved, and onshore liquidity is still insufficient even with extended trading hours.
This reflects a gap between form and substance — MSCI is not asking whether Korea reformed, but whether liquidity actually improved after the reform.
How does thin liquidity amplify risk?
The won hovers near a 17-year low. In off-peak hours, sparse order books can turn modest capital flows into outsized price swings.
Shen Li, Citi's head of Asia-Pacific FX sales in Hong Kong, notes that roughly 20% of spot volume already trades offshore, mostly in the London morning session. This means → extending to 24 hours can improve the overall liquidity structure, but transition-period thin-market risk is real.
Won weakness has a second driver: KOSPI has doubled from its year-start level to a record high, ranking among the world's top gainers — yet offshore funds are taking profits at scale, pushing the won weaker. Korean retail investors are simultaneously buying U.S. equities at record pace, adding to capital-outflow pressure.
How are banks gearing up for round-the-clock operations?
Hana Bank already runs three shifts and plans to add three more staff. Woori Bank plans to double its FX team.
Namkoong Taehun, an 18-year veteran on Hana Bank's FX desk — who traded through the Lehman collapse, the post-Brexit sterling crash, and the 2024 Korean martial-law won plunge — calls the transition "daunting."
In plain terms = a market that never closes demands staffing and systems that never stop. Whether banks can keep up is the practical bottleneck.
What comes next?
Two checkpoints matter: whether the won stays stable under the 24-hour regime, and MSCI's re-review in one year.
The near-term variable is off-peak liquidity — if thin windows produce frequent dislocations, the credibility cost of the reform compounds fast.
This reflects Korea's dilemma: without opening up, MSCI won't upgrade; but if liquidity can't keep pace with the opening, the market becomes more fragile, not less.
