US Stock Market Falls 400 Points

Crude oil notched its largest price jump ever on Friday, leaping nearly $11 to more than $138 a barrel, on news of a weakening dollar and continued jitters over the reliability of world supplies.

The surge, coming just as many analysts thought oil prices were set to fall, sent stocks plunging amid fears that the U.S. economy could be in for a combined bout of inflation and slow growth. The skyrocketing price of oil, now up more than 44% so far this year, is battering the airline and auto industries and causing consumers to cut back on driving and nonessential spending.
