Oil futures rose about 2% on Thursday as a steady improvement in US refining activity offset a surprise build in crude and diesel inventories and on worries that China's new Hong Kong security law could result in trade sanctions.
Brent for July rose 55 cents, or 1.6%, to settle at $35.29 a barrel on its second to last day as the front-month. U.S. West Texas Intermediate (WTI) crude rose 90 cents, or 2.7%, to settle at $33.71.
That move in US crude narrowed Brent's premium over WTI to its lowest since mid-April.
US crude inventories rose 7.9 million barrels last week, exceeding expectations, due to a big increase in imports from Saudi Arabia, the Energy Information Administration (EIA) said.

The market initially fell due to the big increase in crude stocks, but switched into positive territory when it saw the drawdown at the Cushing delivery point for WTI, said Bob Yawger, director of energy futures at Mizuho in New York.
Oil prices have rebounded in recent weeks on anticipation of improved demand after the coronavirus pandemic sapped worldwide consumption by roughly 30%. Overall investment is dropping and US production cuts are balancing out the supply glut, but demand still has not bounced back entirely.
