  • Kospi index dropped 8.3%, triggering a circuit breaker halt in South Korea
  • Brent crude surged 16.1% to $107.61 per barrel, WTI rose 17.7% to $107.02
  • VIX jumped 41% to 32.4, indicating heightened market fear

  • Geopolitical tensions cited as primary driver behind the oil spike

South Korea's Kospi index fell 8.3% in early trading, crossing the 8% threshold that activates a circuit breaker under market rules, halting trading for 30 minutes. The sharp decline mirrored a broader regional selloff, with major Asian indices—including Japan's Nikkei 225 and China's Shanghai Composite—posting steep losses. The downturn was fueled by a dramatic spike in crude oil prices, with Brent crude futures surging 16.1% to settle at $107.61 per barrel, while U.S. West Texas Intermediate (WTI) crude climbed nearly 17.7% to $107.02. The surge marked the largest single-day gain in both benchmarks since 2022, signaling a severe disruption in energy markets. The volatility index, VIX, jumped 41% to 32.4, reflecting a sharp spike in investor fear and risk aversion. Markets across energy and defense sectors saw pronounced pressure, with oil-sensitive equities and defense contractors experiencing outsized losses. The move comes amid escalating regional tensions and speculative concerns over supply constraints, with geopolitical developments in the Middle East cited as a primary catalyst. The energy shock has triggered ripple effects across global supply chains, inflation expectations, and central bank policy outlooks, particularly in Asia.
