Oil prices nudged higher on Monday on tighter supplies from major producers, but a record rise in global coronavirus cases raised concerns a recovery in fuel demand could stall, checking gains.
Brent crude rose 8 cents, or 0.2%, to $42.22 a barrel by 0249 GMT, while U.S. crude was at $39.93 a barrel, up 10 cents, or 0.3%.
Both contracts rose about 9% last week and Brent crude futures have flipped into backwardation, where oil for immediate delivery costs more than supply later, usually an indication of tightening supply.
