South Korea Daily Briefing

Market estimates now place Samsung Electronics and SK Hynix combined Q2 2026 operating profit at approximately ₩150 trillion — a figure that, if realized, would eclipse every prior quarterly earnings record for the two companies. The driver is HBM3E demand from Nvidia, AMD, and hyperscalers building AI training clusters, combined with DRAM pricing that has stabilized and begun recovering after the 2023-2024 correction. SK Hynix's HBM3E is already supply-constrained through 2026 as Nvidia's GB200 and GB300 ramp accelerates. Samsung's earnings recovery is the more important read: the company is closing the HBM yield gap with SK Hynix faster than many analysts expected, and a strong Q2 print would confirm Samsung has re-qualified as a Tier 1 HBM supplier — which opens a significant incremental revenue channel. The ₩150 trillion figure implies roughly ₩90T+ for Samsung and ₩55T+ for SK Hynix on current analyst splits.

Analysis of year-to-date global equity market data shows the Big 3 memory chip companies — Samsung Electronics, SK Hynix, and Micron Technology — have collectively accounted for 22% of the entire increase in global stock market capitalization in 2026. This is an extraordinary concentration: three companies producing fundamentally the same product (DRAM, NAND, HBM) are driving more value creation than entire country indices. For KOSPI investors, this has practical implications — Samsung and SK Hynix together represent over 35% of the KOSPI index weight, meaning KOSPI directionally tracks the memory cycle more than any other single macroeconomic variable. The chaebol discount that used to cap Samsung's multiple on governance concerns is being overwhelmed by the earnings trajectory; institutional investors are treating Korea as a memory proxy rather than an EM market, which structurally reduces the correlation between KRW weakness and KOSPI underperformance.

South Korea's government will cover up to 100% of installation costs for infrastructure supporting semiconductor factory construction in regional clusters — a major escalation of industrial policy support targeting Samsung's planned Pyeongtaek expansion and SK Hynix's Yongin cluster. The policy directly reduces capex hurdles for greenfield fab additions, which matters in the current HBM-capacity-constrained environment: any delay in new DRAM fab construction translates to missed revenue at today's pricing levels. For investors, this is a signal that the Korean government views the semiconductor sector as systemically critical — the kind of policy backstop that reduces execution risk for major capex cycles and narrows the gap between announced capacity and actual volume ramp. BoK is also watching this: government infrastructure support at this scale is inflationary and may complicate the pace of rate cuts the market has been pricing for 2H 2026.
