The World Bank is raising its 2017 forecast for crude oil prices from $53 (£43) per barrel to $55 (£44.9) per barrel.
It comes as members of the Organisation of the Petroleum Exporting Countries (OPEC) prepare to cut production after a long period of unrestrained output.
They agreed to limit crude output to a range of 32.5 million to 33 million barrels per day compared with record output of 33.6 million barrels per day in September.
The Bank’s latest ‘Commodity Markets Outlook’ projects energy prices, which include oil, natural gas and coal, to jump almost 25% overall next year – a larger increase than expected in July.
Oil prices forecast for 2016 remain unchanged at $43 (£35) a barrel on average.
John Baffes, Senior Economist and Lead Author of the report said: “We expect a solid rise in energy prices, led by oil, next year. However, there is considerable uncertainty around the outlook as we await the details and the implementation of the OPEC agreement, which, if carried through, will undoubtedly impact oil markets.”
Metals and minerals prices are also expected to increase by 4.1% next year.
Earlier this year, the Bank projected oil prices to settle in the range of $53 (£40) to $60 (£45) by the end of the decade.
