Headline. Chip momentum holds as the won slides past KRW 1,518/USD, keeping Korea’s export engine strong but pressuring margins.

Top Story

Korea’s semiconductor exports are running hot into mid-2026, an estimated $110.4B in the first four months, driven by AI demand. SK Hynix’s June 7 memory partnership with Nvidia for AI-factory buildout underscores how central Korean memory has become to the U.S. AI stack. The risk is a weaker won, now near KRW 1,518/USD, down ~11% over twelve months, which inflates import costs even as it flatters export revenue.

Trade & Tariff

The U.S.-Korea framework caps tariffs at 15%, with autos and parts cut from 25% to 15%, and Seoul expects retroactive relief from Nov 1. Semiconductors get terms no less favorable than peers. The deal includes $150B for U.S. shipbuilding and $200B for other U.S. industries, capped at $20B/year.

Sector Watch

Semiconductors: production up 13.2% YoY in 2025 with strong momentum this year; a brief bout of profit-taking in Samsung and SK Hynix on June 10 looks like noise, not a trend break. Automotive: the 15% tariff ceiling supports Hyundai and Kia U.S. pricing. Biopharma was quiet.

Korean Corporate Tracker

Samsung: a KRW 450T five-year domestic plan (~$310B), plus a long-range Texas buildout. SK: about KRW 128T domestically through 2028, AI-focused. Hyundai: KRW 125T from 2026-2030 for research, AI, robotics, and autonomy.

Hanwha Watch

Hanwha Philly Shipyard is ramping to ~3 vessels this year, up from roughly 1.5/year, backed by more than $200M in upgrades since December 2024 and a $5B investment commitment. Hanwha is reportedly scouting a second U.S. shipbuilder.

BCW Take

The won’s slide is the quiet story this week. It cushions Korean exporters in the short term but raises the urgency of U.S.-side localization, exactly the bet Samsung, SK, and Hanwha are already placing.
