Oil tumbles as much as 10% and stocks jump after Trump pauses power-plant strikes
Brent crude fell as much as $9.02 to $103.17 a barrel and U.S. crude slid to $90 after Trump's announcement, while S&P 500 futures rose 2.6%. Moves faded after Iran denied talks, but Brent ended back below $100 and the S&P 500 closed 1.1% higher, its best day since the war began.
