1. US Weighs Airstrikes Amid Hormuz Counter-Blockade; Iran Threatens Red Sea Closure

- Key Summary: The Wall Street Journal reported that President Trump is reviewing resuming limited military strikes on Iran immediately after the first US-Iran negotiations collapsed. Iran stated "if they want to pick a fight, we will fight," suggesting it could block the Bab el-Mandeb Strait in the Red Sea, escalating tensions between the two sides. China, which heavily depends on Iranian crude, may pressure the US to lift the blockade at next month's US-China talks, while Japan is considering raising interest rates to address energy-driven inflation, potentially increasing global capital flow volatility. Markets are pricing in approximately 60% probability of a BOJ rate hike, with analysts noting that a yen strengthening could ripple across Asian currencies.

2. Aluminum Prices Surge as China Restricts Sulfuric Acid Exports; Manufacturing on High Alert

- Key Summary: LME aluminum three-month futures surged 11% from pre-war levels to $3,498.5 per ton, the highest in four years. China is reportedly set to completely halt sulfuric acid exports starting next month, with prices already jumping from 464 yuan to 1,045 yuan per ton. Korea imports 97.5% of its liquid bromine from Israel and 64.7% of its helium from Qatar, raising warnings that prolonged Middle East conflict could trigger supply emergencies for critical semiconductor materials. The Korea International Trade Association characterized this as "a structural supply shock combining source concentration with maritime bottlenecks" and proposed transitioning to physical inventory-based procurement systems.

3. Korean Retail Investors Exit US Bonds; $520 Million Sold in 10 Days

- Key Summary: Korean investors' US bond holdings fell to $16.223 billion, declining for seven consecutive months from the September 2024 peak of $22.093 billion and returning to year-ago levels. Net sales in the first 10 days of this month reached $522.17 million, more than triple last month's total of $166.27 million. The US 10-year yield surged 38 basis points from 3.962% pre-war to 4.339%, with analysts saying rate cut expectations have effectively vanished. iM Securities stated that "geopolitical risk-induced energy price floor rigidity is establishing 'high inflation, high interest rates' as the new normal."

4. Deputy PM Koo: "Korea Has No Manufacturing Overcapacity, Contrary to US Claims"

- Key Summary: Deputy Prime Minister and Finance Minister Koo Yoon-chul directly refuted US overcapacity allegations related to the Section 301 trade investigation, stating "our manufacturing facility utilization rates are at appropriate levels." The government plans to strengthen response logic through a public-private joint task force while accelerating supply chain diversification by expanding FTA networks with emerging markets in Southeast Asia, Latin America, and Africa. Plans include approving approximately 3 trillion won annually in EDCF projects over the next three years, with concentrated investment in strategic areas including AI, culture, and supply chains, suggesting expanding investment opportunities in emerging markets. Analysts note that simultaneous US trade pressure and Middle East geopolitical risks could increase earnings volatility for Korean exporters.

5. Vietnam Evolves from Assembly Hub to High-Value Production Base; Chairman Jang In-hwa Personally Oversees Critical Supply Chain

- Key Summary: POSCO Future M (003670.KS) signed a final contract for its first overseas anode materials plant in Vietnam's Thai Nguyen Province, a $400 million (approximately 600 billion won) investment. The facility will have annual production capacity of 55,000 tons with operations targeted for 2028, as major Korean conglomerates including Samsung Electronics (005930.KS), LG (003550.KS), and SK Innovation (096770.KS) expand Vietnam investments. Vietnamese media characterized the investment as "symbolizing a qualitative transformation in FDI," noting it contrasts with China business reductions and demonstrates the direction of supply chain restructuring. A business delegation including Chairmen Jay Y. Lee, Tae-won Choi, Euisun Chung, and Kwang-mo Koo is scheduled to visit Vietnam, with observers expecting announcements of large-scale investments and cooperation projects.

6. Korea Exchange Launches 'HKEX KRX Semiconductor Index' Combining Korean and Hong Kong Chip Leaders

- Key Summary: Korea Exchange developed a joint index with Hong Kong Exchanges and Clearing (HKEX) featuring 15 leading semiconductor companies each from Korea and Hong Kong. The index comprises 60% Hong Kong companies and 40% Korean companies, with plans to utilize the ETF Connect system to expand channels for mainland Chinese investor capital to flow into Korean semiconductor stocks. The institutional foundation was established in July 2024 when mixing with foreign indices was permitted. Analysts expect the convergence of expanding global AI demand and increasing investment demand through Hong Kong to positively impact foreign investor flows into the Korean semiconductor sector.
