The KOSPI index hit a historic 8,000 points before plummeting over 6% due to heavy foreign sell-offs, while government-led mediation for the Samsung Electronics labor strike is set to resume. President Trump returned from China with some progress on bilateral stability, though the issue of arming Taiwan remains unresolved. South Korea is moving to strengthen its international security presence, with reports of a nuclear-powered submarine plan and its participation in a joint declaration supporting freedom of navigation in the Strait of Hormuz.

Top 5 Headlines

1. KOSPI Hits 8,000, Then Plunges Over 6% — A Historic Day

Summary: On Friday, May 15, the KOSPI breached the 8,000-point mark for the first time in history during intraday trading. However, a massive sell-off by foreign investors dragged it below the 7,500 level, ending the day down more than 6%. Heavy profit-taking hit AI semiconductor giants like Samsung Electronics and SK Hynix.
Background & Context: Driven by explosive demand for AI semiconductors, the KOSPI recently hit record highs in a short period. Experts had warned that over-reliance on a few AI chip companies could spike volatility. Rising U.S. Treasury yields linked to Middle East risks (the Iran situation) also dampened investor sentiment.
Impact: Experiencing both an all-time high and a 6% crash in a single day highlights the risks of AI concentration in the Korean market, making portfolio rebalancing essential for both retail and institutional investors.

2. Samsung Electronics Strike D-3… Government Mediation Resumes

Summary: Samsung Electronics and its labor union have agreed to resume government-led mediation on Monday, May 19, just three days before the scheduled mass strike. Yonhap News reported this on May 16.
Background & Context: Earlier, Minister of Economy and Finance Koo Yoon-cheol warned that a strike at Samsung Electronics would pose a severe risk to South Korea’s economic growth, exports, and financial markets. As a core pillar of Korea's exports, any strike could disrupt the global semiconductor supply chain.
Impact: If negotiations fail, further export disruptions and stock price declines are expected. A deal would likely stabilize the market by removing uncertainty.

3. South Korea Plans to Unveil Nuclear Submarine Roadmap This Month

Summary: South Korean government officials and diplomatic sources revealed that a basic plan for the introduction of nuclear-powered submarines could be announced as early as May.
Background & Context: The discussion of nuclear-powered submarines is part of a strategy to secure deterrence against North Korea's nuclear/missile threats and its enhanced Submarine-Launched Ballistic Missile (SLBM) capabilities. It is a sensitive matter requiring coordination within the U.S.-ROK alliance.
Impact: If announced, it would significantly alter the security landscape on the Korean Peninsula, drawing keen attention from neighbors like the U.S. and Japan.

4. Korea Joins 26-Nation Declaration for Free Navigation in Hormuz

Summary: Leaders from 26 nations, including South Korea, issued a joint statement supporting the restoration of normal navigation operations in the Strait of Hormuz.
Background & Context: As tensions escalate in the Middle East following U.S. strikes on Iran, the safety of the Strait of Hormuz—a vital bottleneck for global oil transport—has become a major international issue. Korea has a vital interest in the strait's stability, given its heavy reliance on Middle Eastern crude oil.
Impact: While positive for securing energy imports, it raises the potential for diplomatic friction with Iran.
