Asian Stocks Slide as Oil and Yields Pressure Tech Valuations

Asian stocks fell Monday as rising oil prices and global bond yields raised concerns about expensive tech valuations. South Korea's KOSPI led declines after the Chuseok holiday, while Japan's Nikkei 225 stayed resilient. Foreign investors reduced exposure to semiconductor heavyweights Samsung Electronics and SK Hynix, both dropping over 4%. Japan's chip stocks and a weak yen near 157.5 per dollar offset yield pressures, though Bank of Japan tightening risks remain. Brent crude rose about 2% toward $106.50 per barrel after Trump rejected Iran's Hormuz proposal. Markets priced a 66% chance of another Fed hike, with 30-year Treasury yields near 5.52%, pressuring Asian tech valuations.
