Brent oil climbed to near $55 a barrel as Saudi Arabia’s unilateral output cut eased over-supply fears and a Democratic sweep in the U.S. paved the way for more stimulus spending.

Futures in London rose 0.6% on Friday and rose nearly 6% for the week. Democratic wins in elections in Georgia mean the party is poised to take control of the Senate, House and presidency, spurring a broad move higher in financial markets. That came after Saudi Arabia pledged earlier in the week to cut production by 1 million barrels a day in February and March.
