Nasdaq Hits a High as Borrowing Costs Climb and Oil Stays Dear
The Nasdaq closed at a record even as the dollar rose and Treasury yields moved higher while oil prices eased, according to Oct. 5 coverage. Treasury yields are the interest rates the government pays to borrow, a benchmark for mortgages and business loans. Stock indexes and borrowing rates rose together. Energy moved the other way.
U.S. crude stockpiles fell last week because refineries processed more oil and exports rose, the Energy Information Administration said on Oct. 7. U.S. fuel inventories were mixed last week. Diesel prices were at record highs in early October 2026, and bond yields were at 20-year highs in early October 2026, according to Reuters.
Brent settled down 6 cents, or 0.06%, at $102.25 a barrel on Oct. 2. WTI finished down $1.76, or 1.90%, at $91.11 that day, according to Reuters. Those levels were well above an Aug. 5 settle, when Brent rose 9 cents, or 0.11%, to $79.45 a barrel. They were also above a March 10 print, when Brent dropped 11% to $87.80, according to WSJ market coverage.
Wall Street's record run paused as AI stocks fell and oil prices rose, with the S&P 500 down 0.2% from its all-time high, according to a May 12 report in The Business Journal. On June 24, the Dow rose while the S&P 500 and Nasdaq slipped as worries about AI returned ahead of Micron earnings, and U.S. stocks mostly failed to rebound from a rough start to the week for tech, according to Yahoo Finance. By Sept. 14, European stocks were mixed at the open as chip stocks fell sharply on investor concerns that the artificial-intelligence build-out will slow.
Micron gained 3.5%, according to March 10 WSJ coverage. Software stocks, once market favorites, turned sharply out of favor earlier this year as AI models' coding abilities worried investors, according to July 21 WSJ coverage. Startups and tech giants are mixing and matching AI models to avoid premium prices charged by industry leaders, according to June 11 WSJ coverage. An undated Schwab market update, treated here as background, listed the Cboe Volatility Index at 15.70, up 0.62, and gold at $4,141.30, up $0.60, and noted stocks slid early as oil and yields moved higher.
The broader context here is a market facing two squeezes at once. Think of long-term growth stocks like trees that will not bear fruit for years: when borrowing costs sit at 20-year highs and record diesel lifts freight costs, those distant payoffs look worth less today and daily costs rise. That matters for savers holding stocks and for borrowers facing higher loan rates.
Looking at what this means for positioning, the AI trade is splitting apart rather than moving as one. Chip weakness on build-out worries, software repricing on code automation, and switching models to avoid high prices show investors sorting between equipment spending, pricing power, and staying power. Tight crude with mixed fuels keeps the focus on refining margins and inventory management rather than a simple bet on oil direction.
