Current-reference note: This page uses the Korea Exchange guide as the baseline for ordinary Korean securities-market hours. Holiday schedules, temporary first-trading-day adjustments, broker availability, and future extended-hours programs should be checked at the source before trading.

Regular Session

09:00-15:30 KST

KOSPI and KOSDAQ regular trading hours on ordinary trading days.

Pre-Hours

07:30-09:00 KST

Off-hours session listed by KRX. Available order types and broker access may differ from regular trading.

After-Hours

15:40-18:00 KST

Off-hours trading after the regular close. Liquidity and execution rules can differ from the regular session.

What Overseas Readers Should Remember

Korea uses Korean Standard Time, UTC+09:00.
Korea does not currently observe daylight saving time, so the time difference with the U.S. and Europe changes when those regions switch clocks.
KRX-listed stock settlement is commonly described as T+2 in the KRX trading guide.
January first-trading-day schedules and Korean stock market holidays can change the opening time or close the market.
News headlines may move during U.S. hours, but the cash equity market follows Korean market sessions unless a separate extended-hours program applies.

Extended-Hours Watch

Several Korean media reports in 2026 described a Korea Exchange plan to extend KOSPI and KOSDAQ trading hours from late June 2026. Treat that as a change to verify at KRX, your broker, and official notices before relying on it. This page separates the current KRX guide baseline from reported future changes.
