Crude oil traders might end up liking Secretary of State nominee Mike Pompeo more than his predecessor Rex Tillerson, who formerly ran the world’s largest publicly owned oil company.

Tillerson was a voice of moderation in the Trump administration. He wanted to stick with the Paris climate accord, keep the nuclear deal with Iran and take a measured approach to sanctions against Venezuela.

Pompeo, a former U.S. representative from Kansas and current director of the CIA, would bring a tougher approach to the position.
