Good Monday morning. Updates from the Saudi government on the Aramco plants that were attacked could help determine whether the country will move forward with an I.P.O. for the state-owned oil giant. (Was this email forwarded to you? Sign up here.)

Oil is soaring after the attacks on Aramco

Crude oil prices posted their largest-ever jump in a single day, as Saudi Arabia continues to tally the damage caused by drone strikes on its state-owned petroleum giant, Saudi Aramco.

The price of Brent oil futures shot up as much as 20 percent, its biggest jump since the benchmark was created 30 years ago. It has since retreated a little bit to a 9 percent increase.

Shares in European airlines were down at least 3 percent in morning trading, while those in oil companies were up by about the same amount.
