Oil prices fell on Friday as investors worried that weakening global economic growth and tighter central bank monetary policy could curb a recovery in fuel demand.
U.S. West Texas Intermediate (WTI) crude for June fell $1.76, or 1.58%, to $109.87 on its last day as the front-month.
Brent futures for July rose 85 cents, or 0.77%, to $112.19 a barrel.
The more actively traded WTI contract for July was down 0.82% at $108.99 a barrel.

Open interest in WTI futures fell to 1.722 million contracts on May 18, the lowest since July 2016.

The shutdown following Thursday night’s blast that killed one person is expected to affect already tight gasoline supplies in Asia.
Citi analysts expect S-Oil’s gasoline output to be “severely impacted” in the near term, although it could buy alkylate to maintain production.
Iran, meanwhile, is having a tougher time selling its crude now that more Russian barrels are available.
Iran’s crude exports to China have fallen sharply since the start of the Ukraine war as Beijing favoured heavily discounted Russian barrels, leaving almost 40 million barrels of Iranian oil stored on tankers at sea in Asia and seeking buyers.
