Summary

Cha Young-ju, director of the Wise Economic Research Institute, joined the hosts to explain the rapid two-month appreciation of the won from around 1,500 to 1,300 USD/KRW and why it has left Korean exporters little time to adapt. The discussion covered Hyundai Motor's FX losses, Korean Air's lower fuel and USD lease costs, Samsung Electronics/SK hynix's ability to offset FX through memory pricing, and margin pressure on most other exporters, defense, and shipbuilding. They also debated the appropriate long-term won level and concluded that the near-term path depends on the FOMC dot plot, with 1,300s stabilization potentially reopening opportunities in exporters.

  • USD/KRW fell from about 1,500 to 1,300 in two months, creating adaptation problems for Korean companies.
  • Cha Young-ju said menu costs and low margins make it hard for most exporters to pass through FX losses quickly.
  • Hyundai Motor is negatively affected because its plan assumed about 1,400 won/USD; Korean Air benefits from cheaper fuel and won strength reducing USD lease costs.
  • Samsung Electronics and SK hynix can better offset FX losses through memory ASP increases, and may regain momentum if key levels hold after the FOMC.
  • Defense and shipbuilding sectors face margin vulnerability if the won strengthens sharply, due to low operating margins and competition.
  • A host argued the appropriate long-term USD/KRW level may be 1,000-1,100, while Cha warned that such strong won would be dangerous for export-driven Korean companies.
  • Near-term FX trading is seen as difficult; if USD/KRW stabilizes in the 1,300s after the FOMC and Chuseok, export stocks could be revisited.
Ideas
Cha Young-joo Director, Wise Economic Research Institute 5:09
Won strength hits Hyundai's export earnings.
Hyundai Motor set its annual plan at around 1,400 won/USD, but the won has since appreciated to about 1,300. For an 80 million won Genesis export, the won-equivalent revenue falls from roughly 78-80 million won to about 75 million won, creating FX losses and hurting earnings. Rapid won strength is therefore a negative for Hyundai's results.
Cha Young-joo Director, Wise Economic Research Institute 6:06
Strong won, cheap fuel lift Korean Air.
Korean Air benefits from both lower jet fuel prices, which fell from around 2,000 won to 1,800 won, and a stronger won. About 40% of its aircraft lease and financing costs are USD-denominated, so won appreciation lowers those costs and supports the stock.
Won should strengthen to 1,000-1,100.
Korea's external position is strong: exports have surpassed $1 trillion, Samsung Electronics and SK hynix are global cash generators, and other exporters are solid. Because Korea is highly sensitive to import and energy price shocks, a stronger won around 1,000-1,100 USD/KRW would allow semiconductor leaders to absorb FX losses through shortage-driven pricing power while reducing import inflation for other companies and households. He argues this is the appropriate exchange-rate level for Korea's position.
Cha Young-joo Director, Wise Economic Research Institute 26:28
Defense exporters vulnerable to won strength.
If the won strengthens sharply, Korean defense exporters are vulnerable because their operating margins are only around 8%. Even if they sell weapons, a large FX appreciation can wipe out profits, and they cannot easily pass through the currency hit.
Cha Young-joo Director, Wise Economic Research Institute 26:34
Shipbuilders cannot offset strong won.
Korean shipbuilders have operating margins around 11%. If the won appreciates 30%, raising ship prices by 30% would make them uncompetitive against Chinese shipyards, so they cannot fully offset FX losses. Strong won appreciation is therefore a margin threat for the sector.
Cha Young-joo Director, Wise Economic Research Institute 31:05
Korean exporters face Q3 FX squeeze.
The two-month drop in USD/KRW from around 1,500 to 1,300 was too fast for exporters to adapt. Most Korean exporters have operating margins below 10%, so they cannot fully pass through FX losses into prices, unlike Samsung Electronics and SK hynix. Near term, export companies are a red light, and Q3 earnings risk is significant.
Cha Young-joo Director, Wise Economic Research Institute 37:54
Revisit exporters if won stabilizes.
If USD/KRW stabilizes in the 1,300s after the FOMC and Chuseok holiday, Korean export companies can be revisited. Q3 was disrupted by the rapid FX move and menu costs, but from Q4 the base resets and earnings estimates become more feasible; if the rate stays in the 1,300s, there are enough positive points to look at exporters again.
Cha Young-joo Director, Wise Economic Research Institute 38:44
Memory leaders can rebound post-FX clarity.
Samsung Electronics and SK hynix face near-term FX headwinds and possible Q3 earnings misses, but the market has partly reflected this. Memory ASP increases can offset FX losses because of shortage-driven pricing power. If their key price levels hold and the won stabilizes after the FOMC and Chuseok, the two memory names can regain upward momentum.
