US September CPI came in hotter than expected overnight, with core CPI rising 0.3% m/m against a 0.2% forecast and headline CPI printing at 3.7% y/y, pushing market-implied odds of a Fed rate hike at the late-October meeting to approximately 47%. The stronger inflation print drove a bid in the US dollar, lifted Treasury yields, and soured risk sentiment broadly, with the VIX jumping 10.48% to 16.87 as equity markets sold off sharply — the Nasdaq fell 1.88% and the S&P 500 lost 1.11%. Geopolitical tensions in the Middle East compounded the cautious mood, with attacks on vessels in the Strait of Hormuz and reports of Iranian tactics targeting shipping lanes supporting Brent crude near US$105.91/bbl. The KOSPI was the session's standout casualty, plunging 5.46%, while Japan's Nikkei 225 fell 1.82% as semiconductor-related volatility weighed heavily across North Asian markets.
