Brent crude was down 10 cents, or 0.2%, at $43.04 a barrel by 0047 GMT, after dropping slightly last week. U.S. oil was off by 6 cents, or 0.2%, at $40.53 a barrel, after gaining 4 cents last week.
"With global daily Covid-19 case counts still rising and the U.S. Sunbelt most populous states showing little success in bending and containing the (epidemic's) curve, concerns about the post-Covid recovery pace are limiting the upside for oil," said Stephen Innes, chief global markets strategist at Axicorp.

Japan's oil imports fell 14.7 percent in June from the same month a year earlier, official figures showed on Monday. The drop was not as pronounced as in May when they fell 25%, year on year.
