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.
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.
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.
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.
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.
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.
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.
