Markets closed Tuesday in a clear rotation away from technology and AI-related names, with the Dow gaining 1.03% while the Nasdaq slipped 0.22%, as investors repositioned ahead of the FOMC decision due today at 14:00 ET — a hold at 3.75% is widely expected, though Chair Kevin Warsh's tone and any statement tweaks will be closely scrutinised for hawkish signals. The ECB held its deposit rate at 2.25% on July 23 following its June hike, citing data dependence against a backdrop of 3.0% 2026 inflation forecasts and subdued growth of 0.8%, while geopolitical risk in the Middle East — including Iran-related Strait of Hormuz concerns — continues to embed an energy premium in expectations despite WTI crude falling more than 4% to $79.26/bbl overnight. Defensive and value leadership dominated, with US healthcare (+2.36%), consumer staples (+1.99%), and materials (+1.85%) the top-performing sectors, while technology (-1.84%) and energy (-1.35%) lagged, and the VIX eased 2.46% to 18.21, suggesting contained near-term fear in US markets. Gold pulled back 0.94% to $4,036/oz and US 10-year Treasury yields fell 4bp to 4.65%, supporting the broader rotation into rate-sensitive and defensive exposures.
For Asia-Pacific markets, the most consequential overnight development is South Korea's KOSPI plunging 10.84% — with circuit breakers triggered — on fears over Chinese domestic semiconductor advances, including a major CXMT Shanghai IPO and homegrown DUV lithography machine development, a sharp reminder that geopolitical fragmentation in the chip supply chain carries real and immediate market consequences. Japan's Nikkei 225 fell 3.95% with the Nikkei VIX surging 26.94% to 41.14, reflecting acute stress in the region's technology-heavy indices, while USD/JPY remains elevated at 163.77, keeping intervention risk live ahead of any Bank of Japan commentary. The ASX 200 closed up 0.60% on Tuesday, with ASX VIX easing to 11.16, suggesting Australian investors were relatively insulated, but today's open will need to digest the sharp regional chip-sector selloff, softer Chinese equities (SSE -1.16%), weaker oil and metals prices, and a pending FOMC outcome that could reprice global risk appetite before tonight's session close.
