The S&P 500 dropped to its lowest level in four months on Monday, as a sharp surge in oil prices ignited fresh inflation fears and sent shockwaves through global equity markets.

Market Context

Brent crude futures jumped 8.2% to $92.45 per barrel, while WTI crude rose 7.9% to $88.12 per barrel โ€” both logging their largest single-day gains since early 2024. The move came amid escalating geopolitical tensions in the Middle East and signs of tightening global supply, with OPEC+ maintaining production cuts.

Analysis

The oil spike triggered a broad risk-off move in equities. Energy names outperformed, but rate-sensitive sectors including technology and consumer discretionary bore the brunt of selling pressure. Treasury yields climbed as markets priced in the risk that elevated energy costs could keep inflation sticky for longer, complicating the Federal Reserve's policy path. The VIX volatility index spiked 18% to 24.3, reflecting heightened uncertainty.
