Brent crude reclaiming the $100 mark has triggered a sharp divergence in the South Korean market, boosting refiners while weighing heavily on airlines like Korean Air. The sector is under pressure as prolonged Middle East conflicts drive up fuel costs, which constitute a major portion of operating expenses, and limit carriers' ability to raise fares amid softening travel demand.

  • According to GN stocks/shares-surge, Korean Air dropped nearly 3% to 28,700 won, dragging down peers like Jin Air and Jeju Air as WTI crude surged to $102.48. The report notes that with fuel comprising 30% of operating costs and outbound travel demand slightly declining, carriers lack the pricing power to offset these rising expenses.
