USD/JPY under 150 signals market turbulence
The dollar-yen exchange rate is the indicator he will watch most closely for February. It has already fallen from 158.9 to about 150.8, and past yen-strength episodes (July 2024 and early 2025) coincided with weak global and Korean equity markets. If USD/JPY breaks below 150 he expects market turbulence, so that level marks a shift to risk management, and he will detail it in the February 2 monthly outlook.
Raise cash into early-February KOSPI strength
January ended with a large bullish monthly candle on the KOSPI, and after such monthly gains the upper wicks have historically appeared at the start of the following month. He therefore plans to sell into any additional early-February strength to build cash as a risk-management measure, with details to follow in the monthly outlook.
Hyundai physical-AI re-rating worth monitoring
Hyundai Motor has been re-rated from a legacy automaker to a physical-AI and robotics leader after Boston Dynamics' Atlas humanoid impressed at CES, pushing the stock above 400,000 won and to a 528,000 won close. Hyundai's decade-long art-patronage partnerships (Tate, MoMA, LACMA) reflect a long-cycle philosophy tied to its robotics push, but the column cautions that it is not a buy recommendation, retail chasing has driven a short-term surge, software is being supplemented with Google DeepMind while Tesla's Optimus leverages driving data, and union agreement is required before robots enter plants.
WGBI inclusion lifts Korean government bond demand
Foreigners bought a record 121 trillion won of Korean government bonds in 2025, up more than 150% year on year, ahead of Korea's inclusion in the FTSE World Government Bond Index in November. About 60 billion dollars of passive inflows are expected during the eight-month phased inclusion, which should increase demand, stabilize yields and lower funding costs for the government and corporates, and possibly support the won, though WGBI status is not permanent since Greece, Portugal and South Africa were ejected after downgrades in 2010-2012.
Lithium rebound drives POSCO earnings recovery
POSCO Holdings had a weak 2025 with operating profit down 15.9% to 1.8 trillion won, but the steel division's operating profit rose 20.8% and POSCO International posted a record 1 trillion won. The 2026 rebound thesis rests on lithium, the white oil, up 86% from last year's average at 17.87 dollars per kg, with 43,000-ton lithium hydroxide plants, Argentine brine start-up and an Australian mine stake closing within the year; humanoid-robot and solid-state battery demand add upside, and an analyst quoted sees the fourth quarter as the trough with earnings rising in 2026.
AI growth hinges on power infrastructure
The AI race has shifted from compute and talent to a power-infrastructure bottleneck: data centers need uninterrupted high-quality power, big tech is becoming a power buyer and developer, transformer shortages are delaying grid connections, and renewable intermittency raises system costs. Korea, with limited land and mid-tier solar irradiance, must quickly expand power grids and UHVDC, nuclear including SMR, hydrogen, long-duration storage and demand management, linking energy policy with industrial policy; he concludes that power-infrastructure build-out is urgent.
