Constitution Day Re-designated as Public Holiday: Korean Stock Market Closed on July 17

Constitution Day Re-designated as Public Holiday and Keyword Surge

On July 17, 2026, the re-designation of Constitution Day as a legal public holiday has led to a surge in search volume for the keyword Korean stock market holiday. Investors are actively verifying market operating hours following this regulatory change. In accordance, the Korea Exchange (KRX) has officially announced a full closure of major domestic equity and derivatives markets for the day.

Affected Markets and Closure Details

All trading activities across the following major platforms are suspended for the day according to KRX regulations.

Equity and Securities Markets

Core markets including KOSPI, KOSDAQ, and KONEX are closed. Trading is also suspended for ETFs, ETNs, ELWs, the bond market, and the KSM (Korea Startup Market).

Derivatives and Commodity Markets

• Derivatives Markets: All derivatives markets are closed. Notably, the overnight derivatives market, scheduled to open at 6:00 PM on July 17, is also suspended. However, the overnight trading that commenced on the previous day (July 16) operated normally.
• Commodity Markets: General commodity markets, including the KRX Gold, Petroleum, and Emission Rights markets, are entirely closed.

Settlement Delays and Investor Strategy

Due to the market closure, all scheduled stock trade settlements and fund disbursements are deferred to the next business day. Any volatility in global macroeconomic indicators or foreign markets today will be priced in concurrently when the Korean market reopens tomorrow.

Investors should prepare for potential external uncertainties during this closure. A conservative risk management strategy—confirming market direction post-opening rather than predicting positions aggressively—is highly recommended.
