US stock futures tumbled as energy prices surged following geopolitical tensions in Iran, reigniting inflation concerns that have rattled Wall Street. The selloff extended a weekly decline that marked the steepest drop since October, with investors bracing for higher costs across the economy. Technology and growth stocks bore the brunt of the selling pressure.

Oil prices jumped sharply as fears of a prolonged conflict in the Middle East threatened global supply chains. The energy sector saw gains while other industries faced pressure from rising input costs. Treasury yields climbed as investors priced in the possibility of more aggressive Federal Reserve action to combat inflation. Market volatility spiked as traders weighed the economic impact of sustained higher energy prices.

The market reaction underscores how quickly sentiment can shift when geopolitical events intersect with economic fundamentals. With inflation already a central concern for the Federal Reserve, the latest price spike could complicate the central bank's path forward. Investors are now focused on upcoming economic data and central bank communications for clues about how policymakers will respond to these mounting pressures.
