1. KOSPI’s Historic Rally (2025)
- June 2025: Following President Lee Jae-myung’s inauguration on June 4, the KOSPI index breaks through 2,900 points, marking a technical bull market and its highest level since January 2022 .
- June 20, 2025: KOSPI surpasses the 3,000-point milestone for the first time in three and a half years .
- August 2025: The index continues its upward trajectory, closing above 3,198 points, with a year-to-date gain exceeding 33% .
- October 27, 2025: KOSPI makes history by breaching the 4,000-point barrier for the first time .
- November 3, 2025: The index sets a new all-time closing high of 4,221.87 points .
- December 29, 2025: KOSPI closes the year at 4,220.56, achieving a staggering annual gain of 75.89% – the highest among major global markets. This surge is largely fueled by the AI boom, which drove massive inflows into semiconductor stocks like Samsung and SK Hynix .
2. SK Hynix’s Landmark Bonus Agreement (September 2025)
- In September 2025, SK Hynix and its union reach a historic labor agreement. The company abolishes the previous cap on its Profit Sharing (PS) bonus (which was limited to 10 times the base salary) and commits to allocating 10% of its annual operating profit into an employee bonus pool for at least the next decade .
- For the 2025 fiscal year, with an operating profit of 47.2 trillion KRW, this translated to an average bonus of approximately 140-148 million KRW (about 66,000 – 69,000 USD) per employee for its 30,000+ Korean workforce .
3. The “SK Hynix Uniform” Social Phenomenon (Emerging in early 2026)
- The news of SK Hynix’s extraordinary bonuses sparks a unique social trend in South Korea. The company’s branded work jacket becomes a highly sought-after status symbol in the dating scene, humorously dubbed the “ultimate dating uniform” or “相亲神器” .
- Matchmaking agencies report that SK Hynix employees’ social desirability has skyrocketed, now rivaling traditional elite professions like doctors and lawyers . A viral anecdote suggests employees jokingly tell dates they work at Samsung first, only revealing their true employer at SK Hynix if the match seems promising .
4. Samsung’s Looming Strike (March – May 2026)
- Samsung Electronics’ union, representing over 66,000 members, votes in March 2026, with 93.1% approving a strike. The core grievance is the significant disparity in bonuses compared to SK Hynix .
- Samsung’s existing “Over-Performance Incentive” (OPI) system has a cap of 50% of annual salary. Union demands include abolishing this cap and allocating 15% of the company’s operating profit to the bonus pool .
- After failed negotiations and mediation, the union plans an 18-day full-scale strike from May 21 to June 7, 2026, potentially disrupting global memory chip supply .
