Middle East conflict creates perfect storm for Korean Air post-Asiana merger

Korean Air, having recently solidified its position as a global aviation giant through the acquisition of Asiana Airlines, is now confronting a formidable confluence of external pressures. The Middle East conflict has triggered a sharp increase in international oil prices, directly impacting the airline's bottom line. Fuel costs represent a substantial portion of Korean Air's operating expenses, exceeding 30% of its cost of revenue. The airline has publicly disclosed that a mere 10% fluctuation in oil prices can result in a significant swing of approximately 674.2 billion KRW in its operating profit. This sensitivity was starkly illustrated in 2011 and 2012 when oil prices surged, leading to substantial declines in operating profit compared to periods with lower oil prices.

Korean Air's operating profit decreased by 63% and 74% respectively in 2011 and 2012 compared to 2010, when the international oil price exceeded $100.

The immediate financial impact may not be fully realized in the first quarter of 2025, as many passengers would have booked flights and secured fuel at earlier, lower prices. Furthermore, the recent Lunar New Year holiday season provided a buffer. However, analysts anticipate that the second quarter will bear the brunt of these increased costs. As the industry enters its seasonal off-peak period, a combination of rising fuel prices and the difficulty in immediately passing these costs onto consumers through surcharges will likely squeeze profit margins. While airlines can adjust ticket prices and fuel surcharges, the rapid escalation of oil prices outpaces the ability to reflect these changes promptly, especially for tickets purchased in advance.

Korean Air's operating profit is expected to decrease by a negative (-) 674.2 billion won if oil prices fluctuate by 10% in 2025.

Beyond fuel costs, currency fluctuations present another significant challenge for Korean Air. The airline engages in extensive foreign currency transactions, making it highly susceptible to exchange rate volatility. With substantial foreign currency-denominated assets and, more critically, liabilities, a weakening Korean Won against the US Dollar significantly increases the burden of debt repayment. The airline has estimated that a 10% depreciation of the Won could negatively impact its pre-tax profit by as much as 779.3 billion KRW. While the airline's net foreign exchange gains and losses have historically been managed effectively, the magnitude of recent currency shifts poses a considerable risk.

If the Korean Won weakens by 10%, it could have a negative impact of 779.3 billion won on the company's profit before tax for 2025.

Despite these considerable challenges, Korean Air's strategic positioning and operational resilience offer some reassurance. The acquisition of Asiana Airlines, while adding complexity, also creates a more robust entity capable of navigating industry downturns. The airline's consistent performance, evidenced by its fourth-place ranking in the 2026 World's Best Full-Service Airlines assessment by AirlineRatings.com, and the consistent top performance of Incheon International Airport, signal a strong foundation. The airline's sophisticated risk management, including the use of hedging instruments for oil price volatility and its generally adept handling of currency risks, suggests it is well-equipped to weather these storms, provided the current geopolitical and economic turbulence does not reach unprecedented levels.
