Stocks Finish Lower as Soaring Crude Prices Spur Inflation Fears
WTI crude oil (CLU26) jumped over 5% as Iran and Oman stayed short of a deal to reopen the Strait of Hormuz, with Iran linking reopening to US sanctions, force withdrawal, asset release and compensation. Trump said he would seek compensation from Iran. US rate-hike odds rose; stocks fell, with energy up and airlines, homebuilders down.
How this was made

The 30-second read
Why it matters
The immediate trading driver is crude-led inflation expectations, which pushed Treasury yields higher and rotated sector performance. Several single-name moves are also tied to company-specific guidance, financing, analyst actions, and an acquisition bid.
Market read
Crude-driven inflation fears lifted yields and reshuffled sectors, while company-specific catalysts created outsized single-name moves.
What to watch
The article also cites specific company catalysts (INTC offering, TTD/MNDY guidance misses, VREX acquisition) that can overpower macro correlations for those names.
Background
WTI surged more than 5% on Monday amid stalled talks to reopen the Strait of Hormuz, with Iran’s compensation demands and renewed Middle East attack risk.
Ticker impact
ARM shares fell more than 5% Monday as chipmakers dragged the broader market amid crude-driven inflation fears.
Bias to underperform while crude-driven inflation expectations remain elevated.
The article ties the selloff in chipmakers to the more than 5% WTI surge and rising inflation expectations, with ARM specifically cited among the biggest decliners.
Marvel Technology (MRVL) closed down more than 4% Monday as chipmakers weighed on the broader tape.
Likely remains correlated with the semis complex until crude and rates stabilize.
The text attributes the move to chipmakers moving lower broadly, explicitly listing MRVL among the decliners.
Microchip Technology (MCHP) fell more than 3% Monday as the chip sector sold off with crude prices surging.
Short-term downside bias if yields keep rising with oil.
The article links T-note pressure and inflation expectations to WTI jumping, and includes MCHP among the >3% losers.
Qualcomm (QCOM) dropped more than 3% Monday as chipmakers weighed on equities during the crude-led inflation scare.
May track further semi weakness if oil-driven inflation expectations persist.
QCOM is listed in the group down more than 3% as chipmakers moved lower.
Applied Materials (AMAT) closed down more than 3% Monday, part of the broader chip selloff tied to higher inflation expectations.
Near-term relative weakness versus non-semis if yields remain pressured.
The article explicitly connects the chip sector decline to the WTI surge and inflation expectations, and cites AMAT among the losers.
Nvidia (NVDA) fell more than 2% Monday as crude jumped and inflation expectations pressured rates and tech/semis.
Watch for continued volatility if T-note yields keep rising with oil.
NVDA is singled out as a Dow loser, and the article attributes T-note pressure to the WTI surge boosting inflation expectations.
Alaska Air Group (ALK) fell more than 5% Monday after WTI crude surged more than 5%, pressuring airlines.
Downside bias while oil remains elevated and yields/inflation expectations stay firm.
The article directly states airlines retreated after WTI surged, and ALK is the largest airline decliner cited.
American Airlines (AAL) closed down more than 4% Monday as crude oil jumped and inflation fears weighed on risk assets.
Likely to remain pressured if crude stays bid.
The text links the airline pullback to the WTI surge and lists AAL among the >4% decliners.
Market effects
WTI up more than 5% is driving inflation expectations, pressuring rates-sensitive sectors (housing) and energy-cost-sensitive sectors (airlines), while boosting energy equities.
Overseas equities were mixed-to-higher, but US rates and sector rotations dominated the tape.
Middle East Strait of Hormuz reopening risk is a macro input that can keep crude and inflation expectations elevated across markets.
Counterpoint
The stock moves may be largely mechanical beta to oil and yields, so single-name follow-through could fade if crude stabilizes intraday.
