South Korea's equity markets opened sharply lower on Tuesday, with the KOSPI index (KS11) falling 3.2% to 2,487.13, marking its steepest intraday drop since late 2023. The decline followed escalating rhetoric from Iran, including threats targeting regional shipping lanes, prompting immediate market reassessment of global energy and security risks. The energy sector bore the brunt of the selloff, as international crude prices surged. The U.S. Brent crude futures (CL=F) rose 4.7% to $98.20 per barrel, while West Texas Intermediate climbed 4.3% to $92.65. These moves increased input cost concerns for export-dependent South Korean manufacturers, particularly in automotive and electronics. In contrast, defense-related stocks showed resilience, with Hanwha Aerospace (KRX: 012450) rising 6.5% and Hyundai Rotem (KRX: 086790) gaining 5.1%. Investors appear to be rotating into sectors deemed less vulnerable to geopolitical volatility, reflecting a broader shift toward defensive assets amid regional instability. The market reaction underscores how geopolitical flashpoints can rapidly influence capital flows, even in otherwise stable economies. The energy and defense sectors are now under increased scrutiny as global risk premiums rise, with implications extending beyond South Korea into broader Asian equity and commodities markets.
