Dow futures tumble over 300 points: 5 things to know before Wall Street opens

• Brent crude breached $100/barrel while WTI climbed above $94 following attacks on Gulf energy infrastructure, though markets have not panicked despite inflation concerns
• Apple is unveiling its first foldable iPhone and iPhone 18 lineup today, with investors focused on pricing strategy as Morgan Stanley expects broad price increases and the foldable may exceed $2,000
• Treasury Department will announce expanded bond buyback program details at 11am ET, expected to at least double from current $2 billion cap, which could ease the 10-year yield currently near 4.8%

Market Summary: Dow Futures Drop on Oil Spike and Inflation Concerns

Market Overview:

US stock futures declined Wednesday morning, with Dow futures falling over 300 points (-0.5%), while S&P 500 and Nasdaq 100 contracts each dropped 0.2%. The selloff follows Brent crude breaching $100 per barrel for the first time since July, driven by escalating US-Iran tensions and Gulf energy infrastructure attacks.

Key Developments:

Oil Shock: Brent crude topped $100/barrel while WTI climbed above $94, reviving inflation fears ahead of Friday's CPI data and next week's Federal Reserve decision. The 10-year Treasury yield hovers near 4.8%, approaching 2023 highs.

Apple Product Launch: The tech giant holds its most significant product event in years, unveiling its first foldable iPhone alongside iPhone 18 models. Morgan Stanley anticipates broad price increases, with the foldable device potentially exceeding $2,000. Investors will scrutinize pricing strategy and demand signals under new CEO John Ternus.

Treasury Buyback: At 11 AM ET, the US Treasury announces expanded long-dated debt buyback details. Markets expect at least $4 billion (double the previous $2 billion cap), which could ease long-term yields and support growth stocks.

Sector Performance: AI and technology stocks show resilience despite macro headwinds. Qualcomm rose 1.4% pre-market following Tuesday's 3.2% gain on Amazon partnership news. However, earnings reactions proved volatile—Casey's General Stores fell 8%, Braze dropped 12%, and ServiceTitan plunged 18% on guidance concerns.

Market Implications:

The disconnect between $100 oil and relatively contained equity losses suggests investors aren't yet viewing the energy shock as economy-breaking, though inflation risks remain elevated ahead of critical economic data.
