Holiday weekend closes South Korea cash markets

Holiday weekend closes South Korea cash markets

SEOUL, August 16, 2026, 01:29 KST — Cash trading in South Korea is suspended due to the holiday weekend.

  • The KOSPI rose 11.5%, marking its best weekly performance in two months.
  • The index is still roughly 25% under its closing high from June.
  • Seoul will remain shut on Monday and will resume trading on Tuesday.

South Korea’s KOSPI climbed 11.5% over the past week, snapping a run of seven consecutive weekly losses. Despite the strong recovery, the index remains about 25% under its June closing high.

The significance of that gap outweighs the recent technical bull-market designation. When markets recover 20% following a sharp decline, much of the previous losses remain. To fully offset a 25% drop, the market would require an additional 34% increase.

The rally is still notably focused. Samsung Electronics and SK Hynix were responsible for 71% of the KOSPI’s losses in July. As a result, their recovery significantly impacts the broader index.

Initial figures for peak-to-trough declines and recoveries are based on published closing values. MarketWatch observed a surge from 5,593 up to 6,813 in a span of two weeks, marking the start of a technical bull market.

According to Macquarie analysts, the decline in July was largely driven by positioning and fund flows. They stated, “the volatility is over.” By the end of July, selling by foreign and institutional investors had leveled off. Business Insider

Friday market breadth, early session453 advancers; 420 declinersGains extended past chipmakers, but just barely

The most recent session showed broader movement. SK Hynix advanced 3.01%, but Samsung was down 0.37% during early Friday trade. Hyundai Motor climbed 5.73%, with Kia up 1.97%.

Cross-asset indicators showed less turbulence. The won firmed, trading at 1,416.3 against the dollar. Korean government bond yields for three-year and 10-year tenors declined slightly, and foreign investors were net buyers with 780.2 billion won.

The reaction in both the won and bonds diminishes a near-term risk. Equity advances occurred without the need for a softer currency or increased yields. Overseas inflows indicate reduced reliance on leveraged domestic investors.

Nonetheless, opinions on valuation remain sharply divided. Macquarie’s 8,000 target is just 17% higher than the August 13 close. In contrast, targets from Goldman Sachs and Nomura suggest significantly higher potential gains.

Analyst recommendationKOSPI targetUpside from 6,813.34Core rationale
Macquarie — bullish8,00017.4%Memory supply tightness and normalization of flows
Citi — bullish10,00046.8%Semiconductor profits and government measures
Nomura — bullish range10,000-11,00046.8%-61.4%Market pullback seen as excessive
Goldman Sachs — overweight12,00076.1%Robust earnings improvement in North Asia

Citi has increased its target to 10,000, citing improved profit projections and ongoing fiscal backing. Nomura set its recovery band between 10,000 and 11,000. Both outlooks depend on continued strength in the chip sector.

Strategists at Goldman, headed by Timothy Moe, expressed a preference for North Asia, citing robust earnings growth in the region. The firm’s target of 12,000 reflects an expectation that the current memory cycle will extend further than in previous cycles.

The immediate test carries lower stakes. Staying over 6,800 would maintain the rebound pattern. Advancing toward 8,000 would support Macquarie’s more moderate scenario, though the June high would remain unchallenged.

Investors will have to wait, as Seoul’s market is shut on Monday in observance of Liberation Day. The market reopens on Tuesday, when it will become clear if foreign buying continues after a three-day break.

Risks: Another wave of chip selling could swiftly undo the focused recovery. An increase in oil prices would raise Korea’s import costs. Leverage, holiday interruptions, and ambitious analyst targets could intensify any negative surprise.

Further analysis

Does the KOSPI recovery signal the end of the selloff?
The rebound qualifies under the standard technical criteria for a bull market. The KOSPI advanced approximately 22% between its low point on July 30 and August 13, including an 11.5% increase during the most recent week. However, it was still trading about 25% under its June 22 closing high, leaving a roughly 34% increase from the August 13 close needed for a full recovery.
What makes Samsung Electronics and SK Hynix so important to the index?
Macquarie data shows the two chipmakers made up roughly 71% of the KOSPI’s losses in July. Their collective market capitalization dropped 48% in that period, while the remainder of the index fell by 26%. This concentration means that the memory-chip cycle and overseas demand are key factors for how long the rebound can last.
What key factors should investors monitor as trading in Seoul reopens?
The direction of foreign investment, the won, and Korean bond yields will provide signals on whether the rebound is spreading past a technical uptick. The 6,800 range represents the initial key level for the index, with Macquarie’s 8,000 target suggesting roughly 17% potential gains from the August 13 close. Seoul markets are shut on Monday; global developments over the holiday could result in a gap in prices when trade reopens on Tuesday.
