Why US stock market Dow Jones futures crash today: Dow, S&P 500 and Nasdaq futures turn deep red - Oil surge hits airlines, travel stocks and tech shares

Why US stock market Dow Jones futures crash today: Dow Jones futures plunged more than 300 points to 47,144 today. The US stock market futures turned sharply red as S&P 500 futures fell to 6,744 and Nasdaq futures dropped to 24,870. The selloff followed a sudden oil price surge, with Brent crude near $96 and WTI above $91 after attacks on oil tankers forced Iraq to halt key export terminals. Investors fear wider Middle East war disruption to global energy supply. Rising oil prices hit airlines, travel stocks and tech shares hardest.
