South Korea's benchmark KOSPI index surged over 8 percent on Thursday, May 22, 2026, following a tentative labor agreement between Samsung Electronics and its union that averted a major strike. The resolution of the months-long pay dispute prevented a planned 18-day walkout by approximately 48,000 employees, which had threatened global memory chip supplies.
The agreement, reached on Wednesday night, stipulates that Samsung workers would receive 10.5 percent of the company's operating profits, pending union member approval. This development positively impacted market sentiment, particularly for technology stocks. Samsung Electronics, the world's largest memory chip maker, saw its shares jump over 7.5 percent, while its primary competitor, SK Hynix, surged more than 11 percent.
The broader market rally also extended to non-tech sectors, with automakers Hyundai Motor and Kia both experiencing gains of approximately 13 percent. The KOSPI's performance on Thursday contributed to an overall increase of over 80 percent since the beginning of the year. This market activity coincided with U.S. chip giant Nvidia's announcement of a record $58.3 billion profit in its last quarter, further boosting investor confidence in the artificial intelligence sector.
