Oil Reaches $100 a Barrel, Spurring Inflation Worries and Market Sell-Off

Global equity markets tumbled Tuesday as crude oil futures climbed to $100.23 per barrel on the NYMEX, driven by geopolitical tensions in the Middle East and production cuts from key OPEC+ members. The surge in oil prices intensified concerns over persistent inflation, undermining expectations of near-term rate cuts by the U.S. Federal Reserve and other central banks. The S&P 500 dropped 1.8% to close at 5,124.73, its largest daily decline in three weeks, with energy stocks leading the rally—ExxonMobil (XOM) and Chevron (CVX) both gained over 3.5%—while tech and growth sectors suffered. The broader market sell-off was amplified by a spike in the CBOE Volatility Index (^VIX), which rose to 24.3, its highest level since early January. Bond yields reacted sharply, with the 10-year U.S. Treasury yield climbing to 4.62%, up 12 basis points from the prior session. Higher yields weigh on equity valuations, particularly for high-growth companies with long-duration cash flows. The S&P 500’s forward P/E ratio now stands at 19.4, near the upper end of its historical range, reflecting elevated valuation sensitivity to rate expectations. Market participants are now recalibrating their views on monetary policy. The odds of a Fed rate cut in June, once at 78%, have now fallen to 54%, according to CME Group data. Financials, while benefiting from higher net interest margins, saw mixed performance as rising rates increase lending risks and credit costs.
