South Korea is set to begin 24-hour trading in its onshore foreign exchange market from early July 2026.
This is a significant change aimed at making the Korean financial market more accessible and attractive to global investors. For a long time, foreign investors faced difficulties trading the Korean won outside of Seoul's business hours, creating what's known as 'gap risk'—the risk of prices changing dramatically overnight. By keeping the market open around the clock, this risk is significantly reduced, allowing investors to react to global events in real-time.
The primary motivation behind this reform is Korea's long-standing goal to be upgraded to the 'MSCI Developed Markets Index'. For years, MSCI, a major index provider, has pointed to Korea's limited FX accessibility as a key obstacle. This 24-hour market directly addresses that criticism. It shows a strong commitment to aligning with global standards, which is a prerequisite for the upgrade.
Let's trace the key steps that led to this decision. First, the journey began with gradual changes. In July 2024, trading hours were extended to 2 a.m., and foreign financial institutions were granted direct access to the onshore market. This initial phase proved that extended hours could attract significant trading volume, validating the case for a full 24-hour system.
Second, another major catalyst was Korea's recent inclusion in the 'FTSE World Government Bond Index (WGBI)' in April 2026. This move is expected to bring large, steady inflows into Korean government bonds from global investors. These investors, operating in different time zones, need the ability to hedge their currency exposure at any time, making a 24-hour FX market not just beneficial but necessary.
Finally, the government has been actively preparing the groundwork. In early 2026, the plan was officially included in the national economic strategy. Throughout April and May, top officials held meetings with banks to confirm operational readiness, ensuring that the market infrastructure is robust enough for the transition. This series of deliberate steps has paved the way for the July launch, marking a pivotal moment in the internationalization of Korea's financial markets.
- MSCI Developed Markets Index: A stock market index that represents the performance of large and mid-cap stocks across 23 developed countries. Inclusion is seen as a mark of a mature and accessible market.
- FTSE World Government Bond Index (WGBI): A broad index of global government bonds. Inclusion can lead to significant and stable capital inflows from international index-tracking funds.
- Gap Risk: The risk that a security's price will change sharply from one session's close to the next day's open, with no opportunity to trade in between. 24-hour markets help mitigate this risk.
