[Key Issue Briefing]
■ Joint Nuclear Investment: The government is pushing a plan to form a consortium including Samsung C&T (028260), Hyundai Engineering & Construction (000720), GS E&C (006360), Doosan Enerbility (034020) and SK Innovation (096770) to acquire a 5% to 10% stake in U.S. nuclear power company Westinghouse. The aim is to share with the private sector a financial burden that Korea Electric Power Corp. (015760) and Korea Hydro & Nuclear Power would struggle to carry alone, while gaining a foothold in the market for the eight nuclear reactors to be built in the United States under a Korea-U.S. agreement.
■ China's DRAM Gambit: Chinese chipmaker ChangXin Memory Technologies (CXMT) rattled markets in Korea and the United States by signaling it would unveil 4F² (4F-square), a next-generation DRAM structure that shrinks cell area, within the year. Analysts noted, however, that the announcement used neither "mass production" nor "sample," suggesting it should be read as a product preview. Samsung Electronics (005930) has already presented a working 4F² DRAM prototype, and SK hynix (000660) has disclosed related research results.
■ AI Investment Boom: Bank of Korea Governor Shin Hyun-song said artificial intelligence investment exceeding $1 trillion over the next three to four years would underpin global trade and growth. He also said expanding AI investment and rising energy prices stemming from war in the Middle East were stoking prices at the same time, stressing the importance of monetary policy in curbing inflation.
[News of Interest to Corporate CEOs]
1. Samsung and SK to Buy Westinghouse Stakes Too
- Key points: Major Korean conglomerates are weighing a joint investment to acquire a stake in U.S. nuclear power company Westinghouse. The government is pursuing a plan for a consortium including Samsung C&T, Hyundai Engineering & Construction, GS E&C, Doosan Enerbility and SK Innovation to take a 5% to 10% stake, with the investment size discussed at around 4 trillion won. Investment banking sources say Westinghouse's valuation could rise to $30 billion if it goes public. Even buying in at a 10% discount to the offering price under the Korea-U.S. agreement, securing a 10% stake would cost about $2.7 billion (roughly 3.7 trillion won). SK Inc. and SK Innovation became major shareholders in U.S. small modular reactor (SMR) company TerraPower with a $250 million investment in 2022, prompting speculation that SK Group could emerge as the largest contributor to the private consortium. SK said nothing has been decided.
- Key points: CXMT said it would unveil a server DDR5 memory module (RDIMM) combining a 4F² structure with hybrid bonding within the year, but did not disclose capacity, performance or a mass-production timeline. The 4F² structure cuts the area occupied by a single cell to 2F on each side, theoretically raising density by 50%. But Kwon Seok-joon, a professor at Sungkyunkwan University, said CXMT's 4F² cell, built on a 15-nanometer line width, is similar in area to the 12.2-nanometer 6F² cells used by Korean manufacturers. Samsung Electronics presented a working 16-gigabit DRAM prototype with a 4F² structure at the International Solid-State Circuits Conference (ISSCC) this year. Song Jai-hyuk, Samsung Electronics' chief technology officer and president, confirmed the related technology development at a semiconductor exhibition on the 14th. Hwang Cheol-sung, a chair professor at Seoul National University, said shifting cell structures could be a realistic alternative for China, which faces difficulty securing extreme ultraviolet (EUV) lithography equipment. Some technical estimates suggest initial yields could fall short of 10%.
3. Hanwha (000880) Strengthens Board Independence, Separating CEO and Chair at Key Affiliates
- Key points: Hanwha Group is separating the roles of chief executive and board chair in line with revisions to the Commercial Act aimed at strengthening board independence. Hanwha named Kwon Ik-hwan, an independent director who has served as head of the Ministry of Justice's planning and coordination office and as chief of the Seoul Southern District Prosecutors' Office, as board chair at a meeting on the 14th. Previously, Kim Woo-seok, president and chief executive of the construction division and an inside director, doubled as chair. Following Hanwha Solutions (009830) and Hanwha, the group plans to appoint independent directors as chairs at Hanwha Systems (272210) and Hanwha Ocean (042660) within the year, and at Hanwha Aerospace (012450) and Hanwha Engine (082740) by the first half of 2027. Once the changes are completed by the first half of next year, independent directors are expected to chair boards at six or more affiliates. Hanwha Group will also write into its board regulations the basis for operating a "special committee," a non-standing advisory body composed solely of independent directors, and will establish a "board secretariat" as a support organization reporting directly to the board.

- Key points: Bank of Korea Governor Shin Hyun-song said an AI investment boom would support global trade and growth and have a positive impact on the Korean economy. Speaking in a CNN interview during the International Monetary Fund and World Bank annual meetings in Bangkok, Thailand, on the 14th, Shin said Korea sits at the intersection of two trends: large-scale AI investment and war in the Middle East. He said the two developments work in opposite directions for economic activity but combine to generate inflation on the price front. He also cited Korea as a clear case of a K-shaped economy, stressing that inflation inflicts greater damage on low-income households. The Bank of Korea raised its base rate by 0.25 percentage point in both July and August, and the Monetary Policy Board's next meeting on monetary policy direction is set for the 22nd.
5. "While Korea Delays CPTPP Entry, Auto and Shipbuilding Export Competitiveness Slips"
- Key points: According to a report on Korea's competitiveness before and after the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) took effect, released by the Korea Institute for Industrial Economics and Trade on the 14th, 46 of 90 detailed Korean automobile product categories saw their export competitiveness within the bloc decline when the pre-implementation period of 2012-2018 was compared with 2021-2024. Those categories account for 56.3% of Korea's automobile exports to CPTPP members. In the categories where competitiveness fell, Mexico's revealed symmetric comparative advantage (RSCA) index rose 0.312 while Korea's fell 0.199. In shipbuilding, 15 of 35 categories saw competitiveness within the bloc weaken. Korea's RSCA in those categories fell an average of 0.262 while CPTPP members' rose 0.125, the widest gap among the 15 manufacturing industries analyzed. The institute said attention should be paid to the possibility that Korean products' position in the regional market could weaken further if non-member status persists.
6. Nvidia Opens Vera Rubin Rack Design, Aiming for Data Center Standard Beyond AI Chips
- Key points: Nvidia released the server rack and compute tray designs for its next-generation AI platform, Vera Rubin, at the Open Compute Project (OCP) Global Summit held in San Jose, California, on the 13th. The designs include common specifications for power supply, liquid cooling and network connectivity, and propose a direct-current approach raising voltage to 800 volts in view of the limits that emerge as rack power climbs to about 1 megawatt. Nvidia also unveiled specifications for a CPU-only rack carrying up to 256 Vera central processing units, a move read as a response to demand for infrastructure broadening from a graphics processing unit focus to CPUs and networking equipment as AI agents spread. Research firm IDC projected spending on equipment adopting OCP standards would reach about $800 billion in 2029, 2.7 times last year's forecast of $295 billion. It expects the figure to grow to $892 billion in 2030, 5.8 times the $154 billion seen in 2025.
