South Korea will launch 24-hour dollar-won spot trading from July 6, with a trial period beginning June 29. This initiative is part of a broader foreign exchange liberalisation aimed at securing an MSCI developed market upgrade.
The Ministry of Economy and Finance announced that this will be the first time around-the-clock trading of the dollar-won spot market is allowed. The trial period will provide market participants a week to test systems and build liquidity before the official rollout. Trading will run continuously from 6:00am Monday to 6:00am Saturday in Seoul time, adjusting to 7:00am starts during US winter time. This change eliminates the overnight gap created by the previous 2:00am market close, addressing a significant issue for foreign institutions managing won exposure outside Asian trading hours.
Objectives of the Reform
This reform is part of a sequenced effort by Seoul to internationalise the won and improve its standing with global index providers. The strategic objective is a reclassification by MSCI from emerging to developed market status. Extended trading hours aim to address the challenges offshore investors face in managing Korean currency risk in real time during European and US sessions. A successful reclassification could significantly impact capital flows, as passive funds tracking developed market indices would need to increase Korean allocations.
In addition to extended trading hours, South Korea is relaxing reporting requirements for non-resident participants, simplifying the registration process for foreign institutions, and introducing an offshore won settlement system. This system will allow global players to manage positions without routing everything through Seoul during domestic hours.
Market Conditions and Implications
The timing of this launch coincides with elevated regional currency volatility linked to Middle East energy disruptions and shifting risk sentiment. The trial period will test how the extended market handles stress conditions as well as normal flow. The introduction of round-the-clock dollar-won trading addresses a structural inefficiency that has frustrated offshore participants, particularly in European and US time zones. This reform directly responds to MSCI’s concerns about Korean market accessibility, and a reclassification could trigger substantial passive inflows as global index funds rebalance.
Near-term volatility in USD/KRW during the trial period will be closely monitored, as thinner liquidity in extended hours could amplify market moves until depth builds. This reform arrives at a sensitive moment for the won, with regional currency volatility already affected by global energy price pressures.
