[[LINK_0]]1. Samsung Strike Fallout Spreads to Materials Suppliers… Semiconductor Association Warns of 'Supply Chain Domino' Risk[[/LINK_0]]

- Key Summary: The Korea Semiconductor Industry Association warned that if Samsung Electronics' 18-day general strike planned to begin on the 21st of this month materializes, wafer, gas, chemical and parts suppliers could face cascading impacts. While the union demands institutionalization of operating profit-based performance pay and abolition of the 10% cap, management has proposed expanding special bonuses while maintaining the existing Overall Performance Incentive (OPI) system, with differences remaining unresolved even in post-mediation by the National Labor Relations Commission. The performance pay gap between the memory (300%) and foundry (100%) divisions has emerged as a key contentious issue, while Samsung Electronics' executive leadership released a separate apology statement expressing willingness to engage in unconditional dialogue. The Semiconductor Association urged a swift agreement, stating, "At a time when the entire ecosystem must accelerate in the AI era, progress should not be delayed by a general strike."

- Key Summary: The KOSPI hit an all-time intraday high of 8,046.78 on the 15th, crossing the 8,000 mark for the first time, but closed down 488.23 points (6.12%)—the second-largest drop on record—as foreign investors took massive profits. From the 7th to the 14th of this month, retail investors net-purchased 23.2486 trillion won while foreigners net-sold 26.4179 trillion won, marking a stark contrast; on this day alone, retail investors net-bought 7.1825 trillion won but failed to defend the index. Samsung Electronics and SK Hynix (000660) plunged 8.61% and 7.66% respectively, exceeding the KOSPI's overall decline, while the won-dollar exchange rate closed at 1,500.8 won, up 9.8 won, breaking back above the 1,500 line for the first time since April 7. Kiwoom Securities (039490) assessed that "with the VKOSPI moving above 70, daily return swings of more than 4% would not be unusual."

- Key Summary: AI chip startup Cerebras went public on the Nasdaq on the 14th (local time), closing at $311.07—up 68.15% from its IPO price of $185—with a market capitalization of $67 billion (about 100.4 trillion won) at the close. The IPO sold 30 million shares, raising $5.55 billion, the largest by a U.S. tech company since Uber's 2019 IPO. Cerebras has emerged as an Nvidia challenger by leveraging its Wafer-Scale Engine (WSE) technology, which delivers inference speeds 15 times faster than GPUs, and this year secured a $20 billion cloud contract with OpenAI and a data center supply deal with AWS. With its market value tripling on its first trading day from its February valuation of $23.1 billion, observers say a new variable has entered the AI semiconductor competition landscape.

[[LINK_3]]4. New BOK Board Member's Inaugural Message Warns on Prices and Debt… 'Hawkish Board' Gains Weight[[/LINK_3]]

- Key Summary: In his inaugural address on the 15th, newly appointed Monetary Policy Board member Kim Jin-il simultaneously warned of high oil price-driven inflation from the Middle East war, household debt and housing price risks, and capital flow uncertainties, clearly signaling a price and financial stability-first stance. On economic conditions, he assessed that "improvement is underway, centered on the IT sector, but global investment uncertainty is high and polarization issues persist," and markets interpret the address—which prioritizes risk management over growth stimulus—as a basis for stronger caution on benchmark rate cuts. Kim is a macroeconomic expert with prior experience at the U.S. Federal Reserve, and his term runs through May 2030.
