US stocks fell and oil prices jumped 4% as President Trump warned Iranian negotiators to "better get serious soon" amid reports of stalled peace talks. The Dow Jones Industrial Average dropped 250 points, while S&P 500 and Nasdaq futures dropped 0.8% and 1.1%. Brent crude futures also surged, with West Texas Intermediate crude jumping nearly 4% to $93.83 a barrel. As Tehran continues to maintain its blockade of the Strait of Hormuz, the war in Iran shows no signs of stopping. However, attacks on critical Middle Eastern energy infrastructure could keep prices elevated even if the war ends soon. The US and Iran have each argued their nations have the upper hand in this war.
