South Korea Daily Briefing

SK Group divested SK Siltron, a major silicon wafer supplier to semiconductor makers, to Doosan for ₩2.3 trillion (~$1.67B). Silicon wafers are a critical upstream input to DRAM, NAND, and logic chip manufacturing — and SK Siltron counts Samsung and SK Hynix among its customers. The transaction signals SK Group's portfolio rationalization under the broader chaebol governance reform theme, while Doosan gains strategic semiconductor supply chain assets. For investors: this is a KRW ₩2.3 trillion value realization for SK shareholders and a capability bet by Doosan on the HBM cycle upside.

The Korean government announced it is pursuing special exemptions for its semiconductor mega-zone — including extended working hours beyond the 52-hour cap and 2+2 year contract labor terms. This is direct industrial policy targeting the chip manufacturing complex, aimed at giving Korea's semiconductor fabrication sites the operational flexibility that TSMC and Intel's US plants compete with. For Samsung and SK Hynix investors: if enacted, the exemptions reduce labor cost and scheduling constraints for 24/7 advanced-node fabrication, directly supporting HBM ramp timelines.

Korean news reported KOSPI's 17.91% single-day historic surge, the largest on record — context that explains today's -1.43% as normal consolidation, not fresh selling. The article cited foreign buying rushing in on semiconductor names. For KOSPI investors: the 17.91% session was likely driven by technical short-covering + foreign semicap buying on the global AI chip trade; the bank selling today suggests rotation from financials into tech/semi names that is orderly rather than risk-off.
