Asian stocks tumbled this week after Middle East tensions spiked energy prices, with Korea's Kospi index plunging 12% in two days despite a 10% rebound. Japan's Nikkei 225 also fell, reflecting regional anxiety over potential oil supply disruptions. Energy-import-dependent economies like South Korea—reliant on $10B annual crude imports—face heightened costs if prices stay above $100/barrel, though electronics-dominated markets show muted direct exposure. Chipmakers, accounting for 40% of Korea's market cap, face indirect risks via electricity costs rather than crude prices. Analysts caution prolonged disruptions could outweigh current volatility, but most blue-chip sectors remain insulated from immediate profit impacts.
