Dow futures tumble as Mideast conflict lifts oil, rattles markets

US stock index futures fell sharply on Monday as investors reacted to escalating conflict in the Middle East, with rising oil prices, renewed inflation fears, and a widening geopolitical risk premium weighing on sentiment across global markets.

The decline came after coordinated US and Israeli strikes on Iran over the weekend and subsequent retaliatory attacks across the region, prompting concerns the confrontation could last weeks and disrupt global trade and energy flows.

President Donald Trump indicated operations would continue until US objectives were met, while reports suggested the conflict could stretch for several more weeks.

By early trading, Dow E-mini futures dropped more than 1.11%, S&P 500 futures fell 1.07%, and Nasdaq-100 futures slid about 1.43%.

The CBOE VIX volatility index rose to a three-month high, underscoring rising investor anxiety.

Airlines, banks fall as oil jumps

Airline stocks were among the hardest hit as crude prices surged and flight disruptions spread.

Several carriers halted routes amid regional instability and higher fuel costs.

Delta Air Lines and United Airlines each tumbled more than 5% in premarket trading.

Financial shares also weakened, with Bank of America and Citigroup both falling more than 2% as investors reassessed growth expectations and credit risks.

Oil prices jumped sharply on fears the conflict could threaten supply routes, particularly the Strait of Hormuz, a critical chokepoint for global crude shipments.

US crude rose more than 7% while Brent climbed strongly, increasing concerns about renewed inflationary pressure.

Higher oil prices also weighed on economic outlooks.

Markets already faced uncertainty tied to private-credit risks, artificial-intelligence disruption, and trade tensions.

A prolonged energy shock could compound those concerns.

Safe havens and defense stocks rise

While cyclical sectors fell, investors rotated into defensive assets.

Gold futures jumped, and the US dollar strengthened as traders sought protection from volatility.

Mining shares advanced, with Gold Fields gaining about 1.19% and Barrick Mining rising 2%.

Defense contractors rallied sharply as markets anticipated increased military spending.

Lockheed Martin and RTX climbed roughly 6%, Kratos surged 9%, and AeroVironment jumped more than 12%.

The escalation also deepened fears that regional fighting could widen following retaliatory attacks by Iran and Hezbollah militants.

Inflation fears and economic data ahead

The geopolitical shock comes at a delicate moment for financial markets.

Investors are already coping with elevated inflation readings and expectations that the Federal Reserve may delay interest-rate cuts.

A sustained rise in energy costs could further strengthen that view by keeping price pressures elevated.

Traders are now watching a busy week of economic releases, including manufacturing PMI data, retail sales, ADP employment figures and the non-farm payrolls report.

For now, markets remain in a risk-off posture as traders assess whether the conflict will disrupt energy supplies, prolong inflation pressures and delay monetary easing.
