| Index | At open | At 10:00 | 09:30–10:00 |
|---|---|---|---|
| Dow | -0.18% | -0.5% | -0.5% |
| S&P 500 | -0.18% | -0.3% | -0.3% |
| Nasdaq | -0.17% | -0.1% | -0.1% |
The session was 30 minutes old, so the available interval replaces a full preceding hour.
| Brent | >$90 | +2.5% |
| WTI | $86.40 | +3.6% |
| 10-year Treasury | ~4.75% | Higher |
| VIX | ~15.3 | +6% |
| Energy Select SPDR | $64.15 | +2.35% |
Decliners led by 1.22 to 1.
| PG&E | -19% | Wildfire liability |
| Aon | -5% | USI deal report |
| BioMarin | +5% | Royalty agreement |
| IREN | +2.7% | Post-results rebound |
| Intel | +1% | Semiconductor rebound |
The opening decline broadened as oil crossed $86 and the 10-year yield approached 4.75%. Energy gained 2.35%, but decliners still outnumbered advancers. The market is treating renewed Hormuz conflict as an inflation event, not only a geopolitical headline.
Watch tanker-flow headlines, WTI, the 10-year yield and PG&E contagion across utilities. Lower oil or yields would help technology; another spike would favor energy and deepen pressure on consumers.

The premarket was exactly one hour old, so both columns cover the same available interval.
Two-year Treasury yields, Gulf headlines and airline/utility reactions. Chicago PMI comes later Monday; ISM manufacturing follows Tuesday and payrolls Friday.
