A survey of 37 economists and analysts forecast Brent crude would average $81.95 a barrel in 2023, down from June's $83.03 consensus and current levels of around $85.
Sluggish growth in top crude importer China has also weighed on oil prices so far in 2023.
Global oil demand was expected to increase by about 1-2.1 million barrels per day (bpd) in 2023, led by China.
"China's economic outlook may continue to disappoint but upside in oil demand is still possible with jet demand recovery from international flights later this year," said Ajay Parmar, associate director of global oil markets research at HSBC.
Some of the analysts expected supplies to tighten and support oil prices in the latter part of this year after Saudi Arabia and Russia deepened output cuts in July.
