Why is South Korea launching 24-hour won trading?

South Korea is opening round-the-clock trading for the Korean won to improve access for global investors and support its push for developed-market status from MSCI. Regulators want to modernise the country’s foreign exchange market and reduce friction for overseas institutions. The reform takes effect on July 6.

What changes are being made to Korea’s currency market?

Approved foreign financial institutions will be able to trade the Korean won at any time instead of only during Seoul market hours. Previously, the onshore dollar-won spot market closed at 3:30 p.m. local time before later being extended to 2 a.m. in 2024. The latest reform removes those remaining time restrictions completely.

Why does MSCI developed-market status matter for South Korea?

An upgrade from emerging-market to developed-market status could attract large passive investment inflows from global funds tracking MSCI indices. Many institutional investors allocate capital based on index classifications. MSCI previously cited foreign exchange restrictions and limited currency hedging access as obstacles for South Korea.

How could 24-hour trading affect the Korean won?

Longer trading access could improve liquidity and price discovery for the won by allowing investors to react to global events in real time. It may also reduce the need for offshore trading markets that developed because of restricted domestic hours. However, wider access could also increase short-term volatility during global risk events.

Why has the Korean won been weakening recently?

The won recently traded beyond the 1,410 level against the US dollar due to broader dollar strength and uncertainty around US-Korea economic relations. Global investors have also remained cautious toward Asian currencies amid higher US interest rates and geopolitical concerns. Currency market reforms are happening during this weaker period for the won.

How could this reform impact foreign investors?

Foreign investors will have more flexibility to manage currency exposure and execute trades outside Asian market hours. That could make Korean equities and bonds easier to access for global institutions operating across different time zones. Increased accessibility may improve South Korea’s attractiveness relative to other emerging markets.

Could 24-hour won trading change South Korea’s crypto market?

A more open currency market may improve capital flows and reduce friction between domestic and overseas trading activity. That could potentially narrow crypto price differences between Korean and international exchanges over time. However, crypto regulation and capital controls will still remain important factors.

Q: What is the “kimchi premium” and why is it relevant?

The kimchi premium refers to periods when cryptocurrencies traded at higher prices on South Korean exchanges compared with overseas markets. Capital controls and limited trading access historically contributed to those pricing gaps. Analysts are watching whether freer currency trading reduces some of the distortions linked to Korea’s crypto market.

South Korea will allow 24-hour trading of the Korean won from July 6, giving approved foreign financial institutions unrestricted access to the currency market beyond traditional Seoul business hours.

The reform removes remaining restrictions on the onshore dollar-won spot market after trading hours were previously extended to 2 a.m. in 2024 from the earlier 3:30 p.m. Seoul market close.

The changes form part of South Korea’s long-running push to secure developed-market classification from MSCI, which has repeatedly cited foreign exchange restrictions and limited hedging access as barriers to an upgrade.

MSCI inclusion is closely watched because a shift from emerging-market to developed-market status could trigger significant passive investment inflows from global index-tracking funds.

The timing also coincides with renewed pressure on the Korean won, which recently weakened beyond the 1,410 level against the US dollar amid broader dollar strength and political uncertainty surrounding US-Korea investment relations.

Following the announcement there was no immediate market impact because the reforms will not take effect until July 6.

The overhaul may also affect South Korea’s active retail crypto market, where capital controls and limited trading access historically contributed to the so-called kimchi premium that caused local cryptocurrency prices to diverge from overseas markets.

Analysts said investors will closely monitor whether foreign exchange volumes expand during previously closed trading hours, which could indicate that prior restrictions limited participation in the Korean currency market.
