U.S. oil prices jumped above $90 per barrel early Monday after Tehran issued a stark warning following retaliatory U.S. strikes over the weekend. The U.S. attacks targeted Iranian radar and other command-and-control infrastructure.

Price Movement Details

West Texas Intermediate (WTI) crude rose 1.5% to $90.20 per barrel, driven by fears of a broader Middle East conflict. The escalation comes after the U.S. launched airstrikes on Iranian targets in response to previous attacks.

Market Reaction

Despite geopolitical tensions, stock market bulls remained unfazed, with S&P 500 futures gaining 0.3% and heading for an eighth straight advance. This suggests traders view the military escalation as limited and unlikely to disrupt global economic growth.

Broader Context

The developments come at a sensitive time for energy markets, with oil prices already under pressure from weak Chinese demand and rising U.S. production. However, any further escalation in the Middle East could push prices significantly higher.

What This Means for Investors

Investors should closely monitor geopolitical developments, as any new military action could trigger sharp oil price volatility. Higher oil prices may pressure margins for energy companies like Exxon Mobil (XOM) in the short term but could boost revenues if prices remain elevated.
