The IMF (International Monetary Fund) has said a resurgence in oil exports next year could lower oil prices down by between $5 and $15 a barrel.
Iran is expected to push an additional half million barrels into international markets next year.
It comes after the US and other western powers lifted sanctions against its oil exports.
An estimated 70 energy projects have already been planned in advance.
Iran currently has the world’s fourth largest oil reserves.
The IEA (International Energy Agency) said in a report this month that Iran’s extra oil was one reason behind its prediction that global inventories could climb by as much as 300million
barrels next year.
The IMF said: “While part of this impact may be already discounted in futures markets, a further decline in oil prices could materialise when Iran’s exports rise.”
As of last month, Iran had 36million barrels of oil stored in offshore tankers.
