Hey friends — Tuesday, September 1, 2026, and September is already living up to its “watch your step” reputation.
U.S. stocks opened the new month under pressure after a rough Monday close. Investors are juggling three things at once: hotter oil, higher bond yields, and louder talk that the Federal Reserve might hike rates again this month.
Let’s break it down simply.
What the indexes did
Monday’s close (Aug. 31) set the tone heading into today:
- Dow Jones Industrial Average — down 374.09 points, or about 0.70%, to 53,185.90
- S&P 500 — down 25.62 points, or about 0.33%, to 7,686.14
- Nasdaq Composite — down 31.53 points, or about 0.12%, to 26,370.89
Early Tuesday trading stayed soft. Broad market ETFs like SPY and QQQ were lower in the morning as tech cooled off and energy stayed the odd one out on the upside.
One silver lining: August still finished green. The S&P 500 gained about 2.6% for the month, the Nasdaq about 3.9%, and the Dow about 1.3%. So this isn’t a “crash month” story — it’s a “September chill after a decent August” story.
Why oil is the big headline
Crude jumped as U.S.–Iran tensions flared again over the weekend. Reports pointed to U.S. strikes related to activity near the Strait of Hormuz and Iranian retaliation targeting U.S. bases in Jordan — the first exchange of fire in nearly a year, according to market recaps.
That rattled supply nerves. Brent crude moved above $90 a barrel (reports put Tuesday levels near the low-to-mid $91 range, with Monday settlement around $90.49). WTI also climbed into the mid-to-high $80s.
Higher oil = higher gasoline and freight costs over time. Markets worry that feeds into inflation and keeps the Fed hawkish.
Bonds and the Fed — explained simply
The 10-year U.S. Treasury yield climbed to around 4.78%, its highest level since early 2025. When yields rise, borrowing gets more expensive, and stocks — especially growth and tech — often feel the squeeze.
Fed Chair Kevin Warsh’s Jackson Hole comments that inflation is still “too hot” pushed September rate-hike odds higher. CME FedWatch-style pricing has been pointing to roughly a 60–65% chance of a 25 basis point hike at the September meeting.
Sector snapshot
- Energy — the clear winner on the oil spike
- Utilities — lagged, with California wildfire liability headlines hitting PG&E and Edison International hard earlier in the week
- Tech / software — softer as higher yields pressure rich valuations ahead of big earnings (Dell and Palo Alto Networks after the close today)
What we’re watching next
- Manufacturing and job-openings data midweek
- Friday’s U.S. employment report (economists have been looking for modest August payroll growth after a soft July)
- Tonight’s Dell (DELL) and Palo Alto Networks (PANW) earnings — both are AI/cybersecurity sentiment gauges
- Oil’s path if Middle East headlines keep coming
Bottom line for beginners: rising oil and rising yields are the twin headwinds right now. Energy likes the oil move. Rate-sensitive growth stocks don’t like the yield move. September historically gets choppy — so keep position sizes sensible and don’t chase every headline.
Have a steady trading week. Stay curious, stay patient.
