- Dow Jones fell 620 points per MarketWatch (628 per WSJ) on September 8, 2026, posting its worst day in nearly three weeks as the S&P 500 and Nasdaq also slid.
- Brent crude pushed toward $100 a barrel, with both MarketWatch and WSJ citing rising oil prices as the trigger reigniting inflation worries across U.S. equity markets.
Why it matters: Oil nearing $100 puts the recent inflation cooldown at risk, with the Dow's 620-point drop marking its worst session in three weeks as the selloff swept the S&P 500 and Nasdaq. Energy costs feed directly into consumer prices and corporate margins, reviving fears investors had been pricing away.
