Where Europe Closed Last Session

Frankfurt took the hardest hit on Tuesday. The DAX 40 dropped 1.37% to 25,465.25, its steepest single-session decline in weeks, dragged lower by tech-heavy names that tracked Wall Street’s growing unease over AI valuations. The Euro STOXX 50 followed with a 1.22% loss to 6,319.86, confirming the sell-off was broad across the eurozone core.

Italy’s FTSE MIB shed 0.95% to 52,455.00 while the CAC 40 in Paris fell 0.51% to 8,436.24. Spain’s IBEX 35 held up slightly better at -0.22%, and the AEX in Amsterdam slipped 0.32% to 1,079.00.

The clear divergence was between continental Europe and the defensive markets. The FTSE 100 eked out a 0.13% gain to close at 10,665.90 — its energy and mining heavyweights acting as a buffer. Switzerland’s SMI climbed 0.41% to 14,360.45, with pharma and consumer staples drawing safe-haven flows. The pattern was clean: the more tech exposure in the index, the worse it performed.

US Overnight Snapshot

The Nasdaq Composite fell 1.16% and the Nasdaq 100 ETF dropped 1.85%, making it the worst session for US tech in several weeks. The trigger was multi-pronged: Micron’s stock fell on concerns the memory market is nearing a cycle top, AI-related corporate debt sold off sharply as Amazon moved to borrow another $25 billion, and Microsoft announced fresh layoffs in its Xbox division. The S&P 500 lost 0.45% while the Russell 2000 declined 0.91%.

The VIX rose 3.60% to 16.1 — not panic territory, but enough to signal hedging activity is picking up. The sector split was stark: Technology (XLK) fell 2.39% while Energy (XLE) surged 2.84%. For Europe, the tech read-through is direct — ASML, SAP, and Infineon will face pressure at the Frankfurt open. But London-listed energy names should benefit from the overnight bid.

Commodity + FX Watch

Oil is the story. WTI crude jumped 3.08% to $72.60 after the US launched strikes on Iran and canceled its license to sell oil. That is a direct tailwind for Shell, BP, and TotalEnergies at the European open, and it puts the FTSE 100’s energy-heavy composition in a favorable spot for a second straight session.

Gold edged down 0.25% to around $4,140 — a mild surprise given geopolitical escalation, suggesting the dollar caught the safe-haven bid instead. Copper rose 0.31% to $6.19, a modest positive for European miners like Glencore and Rio Tinto.

In FX, AUD/USD slipped 0.23% to 0.694, reflecting risk-off sentiment. USD/JPY held near 162. A firmer dollar typically pressures euro-denominated exporters, but the energy price surge should more than offset that drag for the UK majors. Watch EUR/USD closely — further dollar strength would support LVMH and Airbus earnings translations but tighten financial conditions across the eurozone.

What to Watch Today

• Iran escalation premium: The overnight US strikes on Iran are the single biggest variable for today’s European session. If crude holds above $72, expect London energy names to lead and the FTSE 100 to outperform continental indices for a second day. Any further military developments during European hours could widen the gap.
• Tech contagion test: ASML, SAP, and Infineon will price in the Nasdaq’s 1.85% drop at the open. Watch whether Broadcom’s customer-loss headline (a major AI client reportedly shifting to MediaTek) spills into European semiconductor sentiment.
• Memory cycle signal: Micron’s sell-off on peak-cycle fears has direct implications for European chip-equipment names. If the memory market is rolling over, ASML’s order book narrative gets harder to defend at current multiples.
• Swiss defensives as a tell: The SMI’s +0.41% gain on Tuesday was a clear rotation signal. If Swiss names continue to attract flows today while the DAX stays under pressure, it confirms the market is de-risking rather than just repricing tech.

Bottom Line

The setup for Wednesday’s European open is split. Energy names have a clear bid from the Iran-driven oil surge, which favors London over Frankfurt and Paris. But tech-heavy indices face a difficult open after the Nasdaq’s worst session in weeks, and the AI valuation questions raised by the debt sell-off and Micron’s warning are not one-day stories. The balance tips slightly risk-off for the region overall — the Luna3 read is to watch whether the DAX can hold the 25,400 level, because a second consecutive 1%+ decline would shift the short-term technical picture.
