NEW YORK—Oil prices hit their highest level in nearly a year on Friday, gaining 8 percent on the week, supported by Saudi Arabia’s pledge to cut output and strong gains in major equity markets.
Brent crude settled at $55.99 a barrel, climbing $1.61, or 3 percent, on the day and 8.1 percent on the week. West Texas Intermediate crude futures (WTI) closed at $52.24 a barrel, gaining $1.41, or 2.8 percent, also its highest since late February. WTI posted a weekly gain of 7.7 percent.
