Korea-US Trade & Investment Intelligence Briefing: Wednesday, June 24, 2026

 

Listen to the audio version   Headline: Korean won closes above 1,540 per dollar, even as the KOSPI surges 3.4 percent on AI chip strength.   Top Story The won settled at 1,541.8 per dollar, its weakest close since March 2009, on a third straight session of dollar strength and Fed rate-hike expectations. The slide cuts both ways for Korea Inc.    On the plus side, a weaker won inflates the local-currency value of dollar revenue, padding margins for exporters like Hyundai, Kia, Samsung, and SK Hynix that bill US buyers in dollars, and it partly offsets the bite of US tariffs by making Korean goods cheaper abroad.    On the minus side, Korea imports nearly all of its energy and much of its raw materials in dollars, so input costs and imported inflation climb just as firms carrying dollar-denominated debt face heavier service costs.    Net read: a tailwind for the export P&L, a headwind for importers and balance sheets, and a flashing signal on capital flows worth watching.   Sector Watch Semiconductors: SK Hynix has overtaken Samsung as Korea's most valuable company on HBM/AI demand, with shares up more than 340 percent this year. The KOSPI jumped 3.4 percent on Wednesday on the chip rally.    Automotive: a weaker won lifts Hyundai/Kia US margins.   Hanwha A Senate Armed Services Committee defense bill (approved June 11) could let the US Navy procure up to two bulk fuel and two strategic sealift vessels from foreign shipyards, a potential opening for Hanwha Philly Shipyard.    Separately, Hanwha Aerospace became Korea's first defense firm to win an S&P credit rating, A- stable, on June 22.   BCW Take A low won plus record AI-chip valuations is a split-screen Korea: pick your exposure deliberately, because the currency tailwind for exporters and the cost headwind for importers are now both real and widening.   New: The Hyundai Way is now available in Kindle, paperback, and hardcover.   Inside the culture, leadership, and strategy that built a global automaker, the work-funneling model, the chaebol timeline, and the five transformation vectors reshaping Hyundai's next decade.   Order on Amazon: https://www.amazon.com/dp/B0GRPDFVNF​ ​ If your team is weighing Korea exposure this year, this is the lens I bring to client work.
