Oil prices CL00, +0.25% rebounded Friday after news reports of a missile strike on a Saudi Aramco facility, with the U.S. crude benchmark settling at $113.90 a barrel. Investors also continued to weigh the path higher for policy rates, with New York Federal Reserve President John Williams saying Friday he would support a half-point move if justified, but indicated it was premature to make a call on the size of a future rate increase.
