Asian stock markets faced a broad selloff on December 15, with the korean stock market particularly hard hit. South Korea's KOSPI index declined sharply, losing 111.31 points to close at 4055.85, marking a 2.67% drop. Japan's Nikkei 225 also faced pressure, sliding 404.45 points or 0.80% to reach 50432.10 at the opening bell.

The korean stock market's steeper decline compared to Japan's suggests heightened volatility in Seoul, where investors are digesting multiple headwinds. Both indexes reflect the broader weakness sweeping across Asia's major equity markets on this Monday session. PANews noted the dual selloff signals investor caution across the region's key bourses.
