Stock Market Today: Dow Plunges 578 Points as Oil Prices Surge and Inflation Fears Return
Brent crude nears $100 a barrel; 10-year Treasury yield hits 4.8%; Fed rate hike probability jumps to 60%
| Updated: September 8, 2026, 4:15 PM ET
The stock market today closed sharply lower as a renewed spike in oil prices rattled investors and reignited concerns about persistent inflation. All three major U.S. indexes finished in the red, with the Dow Jones Industrial Average suffering its steepest drop in weeks.
Here’s how the major indexes performed at the closing bell:
| Index | Change | Final Price |
|---|---|---|
| Dow Jones Industrial Average | ↓ 1.1% (-578 pts) | 52,836.34 |
| S&P 500 | ↓ 0.4% | 7,689.63 |
| Nasdaq 100 | ↓ 0.4% | 29,418.83 |
Despite today’s decline, the S&P 500 remains up more than 12% year-to-date. However, the combination of surging energy costs and rising bond yields is testing the market’s resilience.
Why Is the Stock Market Down Today?
The primary catalyst behind today’s selloff was a sharp jump in crude oil prices, driven by escalating geopolitical tensions in the Middle East.
Oil Prices Approach $100
- Brent crude futures surged toward $100 per barrel following fresh attacks on Saudi Arabian energy infrastructure.
- Ongoing conflicts involving Iran and the U.S. have heightened concerns about global supply disruptions.
This energy shock quickly spilled over into bond markets.
Treasury Yields Climb Above 4.8%
The 10-year Treasury yield jumped above 4.8% —its highest level since late 2023. Higher yields make borrowing more expensive for companies and consumers, weighing on stock valuations—particularly for growth and technology shares.
Fed Rate Hike Odds Jump to 60%
Wall Street’s attention has pivoted squarely back to the Federal Reserve following last Friday’s blockbuster jobs report.
August Jobs Report Beats Expectations
- The U.S. economy added 162,000 jobs in August—triple the consensus forecast.
- The strong labor market data has given the Fed room to act on inflation without fearing a recession.
Rate Hike Probability Surges
According to CME Group’s FedWatch Tool:
Probability of a rate hike at the Sept. 15–16 FOMC meeting: ~60%
That’s up sharply from just one week ago, when markets were pricing in a near-zero chance of a move.
Key Inflation Data Ahead: CPI Report in Focus
Investors are now bracing for two critical inflation reports later this week that could seal the Fed’s decision.
| Date | Report | Why It Matters |
|---|---|---|
| Thursday, Sept. 10 | Producer Price Index (PPI) | Measures wholesale inflation—early signal of consumer price trends. |
| Friday, Sept. 11 | Consumer Price Index (CPI) | The most-watched inflation gauge; will show if oil costs are feeding into broader price increases. |
A hot CPI print on Friday could push rate hike odds to 80% or higher, while a cooler reading might calm markets.
Stock Movers: Tesla Gains, Amgen Plunges
Not all stocks followed the market lower today. Here are some of the biggest movers:
Top Gainer
- Tesla (TSLA): +3% – Shares rebounded from recent post-Cybercab event weakness, leading gains among megacap tech names.
Biggest Loser
- Amgen (AMGN): -10% – The biotech giant tumbled after Novartis reported a failed trial for a similar heart drug, casting doubt on Amgen’s own experimental treatment in the same class.
Semiconductors: Mixed Performance
- Nvidia (NVDA): Down slightly
- Microsoft (MSFT): Down slightly
- Intel (INTC): Up
- Qualcomm (QCOM): Up
The mixed results in semis suggest investors are selectively rotating into value-oriented tech names.
What to Watch Tomorrow
With after-hours trading now underway, here’s what investors should keep an eye on:
- Geopolitical developments in the Middle East—any escalation could send oil even higher.
- Overnight futures—will they signal a rebound or follow-through selling?
- Wholesale inflation data (Thursday) and CPI (Friday) remain the week’s main events.
Bottom Line: Is This a Buying Opportunity or a Warning?
Today’s selloff reflects genuine macro concerns—rising energy costs, sticky inflation, and a Fed that may not be done hiking. However, history shows that pullbacks driven by geopolitical shocks often present buying opportunities once the dust settles.
Key takeaway: This week’s CPI report will likely determine the market’s next major direction. Until then, expect volatility.
