US and European equities slid across the board on April 23, 2026, as persistently elevated oil prices and stalling Iran peace talks weighed on investor confidence. The S&P 500 fell 0.41% to 7,108.40, putting it on course for its first weekly loss since March — even as Intel’s blockbuster after-hours AI forecast flipped Nasdaq 100 futures sharply higher and pointed toward a tech-led rally for Friday’s open.
US Markets: Oil Drags Indices Lower; Intel After-Hours Reversal
All three major US benchmarks closed lower on April 23. The S&P 500 ended at 7,108.40 (−0.41%), the Dow Jones Industrial Average dropped to 49,310.32 (−0.36%), and the Nasdaq Composite fell to 24,438.50 (−0.89%) as the tech-heavy index bore the brunt of rate and energy concerns on the session.
The primary headwind was oil. Brent crude extended its Iran war rally above $105/barrel (+1.7% on the day) as the Strait of Hormuz recorded just 1 ship transit — down 103 from pre-war levels. Persistent Hormuz disruption reinforces inflation risks and raises the prospect that the Federal Reserve will hold rates higher for longer, pressuring equity valuations particularly in rate-sensitive growth sectors.
Geopolitical uncertainty added to the unease. A Bloomberg exclusive revealed that Trump’s combative Truth Social posts and continued naval blockade are actively hindering Pakistan-mediated Iran peace negotiations, dimming near-term hopes for a Hormuz reopening and the oil relief that would bring. The Israel-Lebanon ceasefire extension of three weeks provided only a narrow de-escalation signal on the western front.
The turnaround came after the bell. Intel delivered a blockbuster June quarter guidance of $13.8–$14.8 billion — crushing the $13 billion Wall Street consensus — confirming that AI data center investment is translating into real silicon demand at scale. Intel shares surged 22% in aftermarket trading, and Nasdaq 100 futures rose 0.6%, putting the index on course for a fourth consecutive weekly gain. The session’s weakness became secondary to what the Intel print signals for the broader semiconductor ecosystem.
Europe: Germany’s Business Outlook Hits Worst Level Since 2023
European equities fell across all major indices on April 23, anchored by the worst German business sentiment reading in nearly three years. The DAX closed at 24,084.40 (−0.29%), the FTSE 100 ended at 10,401.00 (−0.54%), the CAC 40 dropped to 8,156.04 (−0.87%), and the Euro Stoxx 50 fell to 5,869.23 (−0.43%).
The key data shock came from Germany. The Ifo Institute’s expectations index fell to 83.3 in April from a revised 85.9 in March — the lowest since August 2023 and well below the 85.5 Bloomberg consensus. Both the forward-looking expectations sub-index and the current conditions gauge deteriorated more than forecast, a sign that Europe’s most critical industrial economy is struggling to absorb the Iran war’s energy price shock. Germany is structurally exposed: as a heavy industrial base importing natural gas and oil, $105+ Brent and elevated European gas prices directly erode manufacturer margins.
Trade uncertainty compounded the pressure. The European Commission warned member states that efforts to strengthen safeguards in the EU-US trade agreement risk unraveling the deal altogether. The commission told ambassadors that several proposed amendments by lawmakers could sink the accord, adding another layer of geopolitical risk premium to European equities.
Not all was negative. Europe’s largest software company, SAP SE reported Q1 cloud revenue of €5.96 billion, edging above the €5.9 billion analyst estimate as the company’s AI integration push gained traction. The earnings beat provided a partial offset for German tech/software equities, but was insufficient to turn the broader DAX positive against the macro headwinds.
Macro Variables: Oil, Bonds, and the Rate Outlook
The macro picture remains dominated by Brent’s sustained elevation above $105 — up 46%+ since the Iran war began. Historically, oil shocks of this magnitude take 6–12 months to fully pass through to CPI. With Federal Reserve officials already weighing the inflation persistence narrative and Fed Governor Warsh reported to be seeking better data on the inflation path, the market is pricing limited room for rate cuts in 2026. US 10-year Treasury yields remained elevated, reflecting the stubborn oil/inflation nexus.
The dollar held steady. The Bloomberg Dollar Spot Index stood at 1,199.4, up about 1% since the war began. For Asian exporters — particularly Korean manufacturers with USD-denominated revenues — dollar strength offsets some of the energy cost impact, but the net effect depends heavily on each company’s import exposure.
What to Watch on April 24 (Asia Open)
- Intel aftermath for chip stocks: The 22% Intel premarket surge is the most important signal for Samsung Electronics, SK Hynix, and the broader KOSDAQ tech index at Friday’s open. AI server demand is real and accelerating.
- Ifo data ripple: Germany at business sentiment lows reflects the Iran war’s structural drag on European industry — relevant for Korean and Japanese manufacturers competing in the same supply chains.
- Brent above $105: Watch Korea CPI and Japan CPI as the energy price transmission into consumer prices continues to build.
- Iran talks barometer: Any sign of resumed Islamabad-mediated talks would immediately reprice oil downward and lift rate-sensitive equities globally.
- Nasdaq 100 futures momentum: If Nasdaq 100 futures hold their Intel-driven +0.6% gain into Asia open, expect risk-on sentiment across KOSPI and Nikkei.
