Reuters poll: Crude oil seen averaging $55.78 per barrel in 2018

A higher estimate compared to last month's poll of $54.78

This was a Reuters survey on 32 economists and analysts. Here are the rest of the poll details:

• Crude oil seen averaging $57.78 in 2019
• Previous poll $57.01
• Brent oil seen averaging $59.88 in 2018
• Previous poll $58.84
• Brent oil seen averaging $61.31 in 2019
• Previous poll $60.79

All the estimates are higher as the respondents attribute strong OPEC compliance as well as strong global demand growth - particularly from Asia - are likely to keep oil prices underpinned.
