Oil prices rise, but not by enough to keep Wall Street from more records
Oil prices rose after renewed fighting threatened the U.S.-Iran ceasefire, with Brent settling up 4.2% at $94.98. U.S. stocks still hit more records: S&P 500 +0.3% to 7,599.96, Dow +0.1% to 51,078.88, Nasdaq +0.4% to 27,086.81. Airlines fell (United -2.6%, Alaska -3.3%). Treasury 10-year yield briefly neared 4.52% before easing to 4.46%.

Near-term risk is continued margin pressure if oil stays elevated; equity move already reflects part of the shock.
United Airlines fell 2.6% as Brent crude jumped 4.2%, highlighting direct cost pressure from higher oil prices.
Choppy to downside bias while oil remains firm; watch for stabilization if yields ease.
Background
The piece frames Monday’s equity strength as driven by AI/mega-cap leadership and better-than-expected earnings, while oil/Iran risk lifts crude and initially pushes yields higher.
Why it matters
Oil-driven inflation and yield pressure created dispersion (airlines down), but intraday yield regression and company-specific catalysts (NVDA product updates, SAIC earnings beat, M&A bids) supported broader indices.
Market relevance
This is a cross-asset tape read: crude/Iran risk lifts oil and yields, but mega-cap AI and discrete earnings/M&A catalysts dominate index direction today.
Market effects
Higher oil and higher yields pressure rate-sensitive and fuel-burdened names (airlines, growth/AI capex financing), while AI/mega-cap leadership supports index level.
Asia strength (Tokyo record; SoftBank rally) and Korea export data reinforce global risk appetite, partially offsetting oil-driven caution.
Iran ceasefire risk is a cross-asset driver via crude and sovereign yields; any escalation would likely widen dispersion across cyclicals and defensives worldwide.
Alternative perspectives
Oil rose but stocks still hit records; the market may be pricing a limited duration of the Strait-of-Hormuz risk rather than a sustained inflation shock.
The article notes yields regressed intraday—if that move reverses, airline and rate-sensitive names could underperform even if mega-cap AI stays strong.
