Tuesday's session was defined by a sharp rotation out of AI-linked semiconductor names, with the VIX spiking 12.79% to 19.49 and the Nasdaq shedding 2.21% to 25,587 — its steepest single-session loss in recent weeks. The trigger was a collapse in memory chipmakers: Micron fell 11.4%, Taiwan Semiconductor 5.2%, and the VanEck Semiconductor ETF dropped 6.5%, as Broadcom's results failed to deliver the forward guidance uplift markets had priced in. Simultaneously, US Treasury yields rose 5bp across the 2- and 10-year to 4.24% and 4.51% respectively, reinforcing the hawkish Fed narrative after Chair Warsh's debut FOMC meeting lifted the median 2026 rate-end projection to 3.8% and stripped out the easing bias. Crude oil continued its Iran-driven descent, WTI settling near $73.21/bbl after the US issued a 60-day oil sanctions waiver on Iran and satellite data confirmed rising Strait of Hormuz ship crossings.
For European investors, the transmission channels are direct and multiple. The STOXX 50 fell 1.28% and the AEX led European index declines at -1.60%, reflecting the Netherlands' outsized exposure to ASML, which dropped 5.74% — its heaviest one-day loss since the Asian chip rout. The MIB fell 1.46%, dragged by Stellantis (-6.74%) amid persistent auto-sector headwinds, while the DAX shed 0.98% as Infineon (-6.26%) amplified the semiconductor contagion. EUR/USD slipped 0.31% to 1.1427, touching its weakest level since June 2025, as mixed Eurozone PMI data and the stronger dollar combined to squeeze the euro; EUR/GBP fell a sharper 0.61% to 0.8626, with sterling outperforming on relative UK macro resilience. Copper fell 3.39% and aluminium 3.16%, pressuring Basic Resources, while silver's 5.35% drop added to broad commodity-sector stress.
