[Key Issue Briefing]
■ Triple shock from rates, oil and the won reignites: The yield on three-year Korean treasury bonds broke above 4% to 4.014%, the first time in two years and 10 months since November 2023, while West Texas Intermediate and Brent crude both topped $100 a barrel. A senior official in the financial industry warned that if the Federal Reserve holds rates steady, high interest rates, high inflation and a high exchange rate could all erupt at once.
■ KOSPI breaks below 7,000 as large caps fall broadly: The KOSPI plunged 124 points, or 1.76%, to close at 6,909.91, surrendering the 7,000 level after three trading sessions. Most of the largest stocks by market capitalization finished in the red, including Samsung Electronics (005930) down 3.53%, SK hynix (000660) down 2.21% and SK Square down 4.05%. Losses were especially pronounced among semiconductor equipment makers, with Wonik IPS down 7.15%, Jusung Engineering down 5.43% and PSK down 5.60%.
■ Next week's FOMC and Bank of Japan meetings loom as a "big week": With the Federal Open Market Committee meeting on the 15th and 16th followed by the Bank of Japan's monetary policy meeting on the 17th and 18th, pressure for a rate increase is mounting after August core U.S. consumer prices rose 0.3% from the previous month, above the 0.2% forecast. The Chicago Mercantile Exchange's FedWatch tool at one point put the probability of a 0.25 percentage point rate increase at this FOMC meeting as high as 90%.
[News of Interest to Stock Investors]
1. Three-Year Yield Tops 4% Amid Trump-Driven Triple Shock
Key summary: The three-year treasury yield closed at 4.014% and the 10-year at 4.540%, both setting successive highs for the year. August consumer prices rose 3.4% from a year earlier, and the won-dollar exchange rate jumped 6.7 won to 1,345.9. Choi Jae-won, a professor of economics at Seoul National University, explained that if inflation risk grows further, selling demand for bonds could pile up and push treasury yields higher still.

Key summary: The KOSPI closed at 6,909.91, giving up the 7,000 level. The seizure of the Bab el-Mandeb strait by Yemen's Houthi rebels created a double bottleneck at the Red Sea and the Strait of Hormuz, sending WTI surging 6.69% to $102.48 a barrel. Samsung Electronics fell to 259,500 won, down 3.53%, and SK hynix to 1.812 million won, down 2.21%.
