2026 Korea Market Calendar: Trading Hours, Holidays & Key Dates
Trading Korean equities effectively means respecting the local clock and calendar. Korea observes long holiday breaks that can halt the market for several consecutive days, and it has recurring dates — from options expiry to a nationwide exam day — that reliably shape liquidity and volatility. This guide maps out the essentials for 2026.
π Daily Trading Sessions
| Session | Time (KST) | Notes |
|---|---|---|
| Pre-Market Auction | 08:30 – 09:00 | Single-price call auction sets the open. |
| Regular Session | 09:00 – 15:30 | Continuous trading. |
| Closing Auction | 15:20 – 15:30 | Single-price auction sets the close — often volatile on expiry days. |
| After-Hours | 15:40 – 18:00 | Off-hours single-price trading; thin liquidity, low reliability. |
ποΈ Key 2026 Market Holidays
The market is closed on the following major public holidays. Note that the two biggest — Seollal (Lunar New Year) and Chuseok — close the market for roughly three consecutive days. Always confirm exact dates and any substitute holidays with the Korea Exchange (KRX).
| Holiday | 2026 Date(s) |
|---|---|
| New Year’s Day | January 1 |
| Seollal (Lunar New Year) | Mid-February (approx. Feb 16–18) |
| Independence Movement Day | March 1 |
| Labor Day | May 1 (financial markets closed) |
| Children’s Day / Buddha’s Birthday | Early / late May |
| Memorial Day | June 6 |
| Liberation Day | August 15 |
| Chuseok (Harvest Festival) | Late September (approx. Sep 24–26) |
| National Foundation / Hangeul Day | October 3 / October 9 |
| Christmas | December 25 |
| Year-End Closure | December 31 (market holiday) |
β‘ Recurring Volatility & Event Dates
– Monthly Options Expiry: The second Thursday of every month. Program-trading flows around expiry can whipsaw the index intraday.
– Quarterly “Witching” Days: In March, June, September, and December, index futures and options expire simultaneously — Korea’s equivalent of “quadruple witching,” with the largest volatility.
– Earnings Season: Quarterly. Bellwethers like Samsung Electronics release preliminary results early in the month following each quarter-end, setting the tone for the market.
– Index Rebalancing: KOSPI 200, MSCI, and FTSE reviews periodically reshuffle constituents, driving passive-fund flows into and out of affected names.
π Uniquely Korean Calendar Quirks
– Suneung (College Exam Day): On the day of the nationwide university entrance exam (typically mid-November), the market opens one hour late, at 10:00 KST, to ease morning commuter traffic for students.
– First Trading Day of the Year: The market traditionally opens later, around 10:00, following an opening ceremony.
π‘ Lingo Check: Calendar Terms
– Single-Price Auction (λμνΈκ°): A call-auction mechanism that matches all orders at one price — used at the open, the close, and after volatility halts.
– After-Hours (μκ°μΈ): The thin post-close session; prices here often do not carry over to the next day.
– Witching Day (λ€ λ§λ μ λ ): Literally the “day of the four witches,” Korea’s term for simultaneous futures-and-options expiration.
– Suneung (μλ₯): The national college entrance examination — the one day a year the stock market deliberately opens late.
π‘οΈ Conclusion: Trade the Clock
A market’s calendar is part of its risk profile. Korea’s long holidays, monthly expiries, and quirks like the Suneung late open are predictable — and predictability is an edge.
