Warsh's Jackson Hole Warning Meets Washington's Fab Demand: Reading Korea's Chip Trade Into September Warsh's Jackson Hole Warning Meets Washington's Fab Demand: Reading Korea's Chip Trade Into September By Leo Jaeyoul Lim | CEO, SEJONG DnC Market observer since the 1990s · August 31, 2026 · Global Macro · Korea Semiconductors · ~11 min read Two pressure points that had been building on separate tracks all August converged in the same 48-hour window last week. On August 28, Fed Chair Kevin Warsh used his first Jackson Hole keynote to warn that inflation "has not meaningfully slowed," pushing market-implied odds of a September rate hike sharply higher. Three days earlier, Washington escalated its own pressure on Samsung and SK hynix to build wafer fabrication capacity on US soil, a demand that followed directly from Korea's own $577 billion Honam semiconductor cluster announcement. Having watched a number of Fed transitions an...

Korea's Last Structural Play Against China: Physics-Informed Industrial AI and the Economics of the AX Transition Korea's Last Structural Play Against China: Physics-Informed Industrial AI and the Economics of the AX Transition By Leo Jaeyoul Lim | CEO, SEJONG DnC Market observer since the 1990s · August 29, 2026 · Korean Manufacturing · Industrial AI · ~19 min read Two numbers, released nine days apart this summer, tell you almost everything about the strategic position Korean manufacturing is in right now. On July 12, a Korea Institute for Industrial Technology (KEIT) survey leaked to local press showed the technology gap between Korea and China had collapsed from 5.0 percentage points to 1.1 in just two years, with China now outright leading in autonomous vehicles and intelligent robotics. On June 29, the Korean government answered with a very different number: a joint public-private commitment of 20 trillion won by 2030, aimed at producing more than 100 trill...

Nvidia's $279B Supply Surge Meets Korea's Chip Rally: What the Q2 Print Means for Samsung and SK Hynix Nvidia's $279B Supply Surge Meets Korea's Chip Rally: What the Actual Q2 Print Means for Samsung and SK Hynix By Leo Jaeyoul Lim | CEO, SEJONG DnC Market observer since the 1990s · August 28, 2026 · Semiconductors · Korean Markets · ~11 min read Two days ago, this column asked whether Nvidia's fiscal second-quarter print would tip the competitive balance between Samsung and SK hynix any further. The results are in, and they cleared a bar that was already set high. Nvidia posted $96.2 billion in quarterly revenue, up 106% year over year, and disclosed that supply commitments -- the forward orders locked in with its component partners -- have more than doubled to $279 billion. Samsung Electronics and SK hynix opened Wednesday's Korean session sharply higher on the news, with SK hynix up as much as 5.81% intraday. But roughly 90 minutes lat...

Picks, Shovels, and Denim: The Real Winners of the AI Infrastructure Build-Out Picks, Shovels, and Denim: The Real Winners of the AI Infrastructure Build-Out By Leo Jaeyoul Lim | CEO, SEJONG DnC Market observer since the 1990s · August 27, 2026 · Startups & Venture Investing · ~13 min read During the 1849 California Gold Rush, the people who reliably got rich weren't the prospectors panning for gold -- they were the merchants selling durable canvas trousers to the miners. Levi Strauss built a lasting business not by finding gold, but by solving a mundane, unglamorous problem every miner shared. Three years into the current AI boom, the same pattern is repeating in plain sight. The foundation-model companies burning cash to train ever-larger systems remain, for the most part, unprofitable. Meanwhile, the businesses solving AI's physical bottlenecks -- power, cooling, and compute financing -- are already generating tens of billions in backlog and revenue. This...

HBM4 Rivalry Meets Nvidia Earnings: Korea Chip Stocks Outlook HBM4 Rivalry Meets Nvidia Earnings: What It Means for Korea Chip Stocks By Leo Jaeyoul Lim | CEO, SEJONG DnC Market observer since the 1990s · August 26, 2026 · Semiconductors · Korean Markets · ~10 min read Nvidia reports its fiscal second-quarter results after the US market close on August 26, and few storylines will be watched more closely in Seoul than what its guidance implies for the HBM supply chain. Samsung's HBM4 yield has climbed from below 60% in February to roughly 80% by August, a faster recovery than most analysts penciled in six months ago. SK hynix, meanwhile, still commands the largest share of the HBM market by most measures, even as that share has narrowed. Having watched several memory cycles compress and release since the 1990s, I think the more interesting question for institutional readers isn't simply whether Nvidia beats -- it almost certainly will clear a low bar -- but whe...
