[EN] Fast rise in oil prices in the last decade and downward trend since June 2014 have raised the issue of identifying long term cycles (super-cycles) in oil prices. To this aim, in this study firstly super-cycles in oil prices are identified and which phase of the cycles oil prices are in is investigated. Results indicate that in the last 150 years there are three identified super-cycles in oil prices. Latest super-cycle in oil prices, started in the second half of 1990s, has been in the contraction period since 2013 and is expected to last in 2018. As our results indicate, oil prices continue stay low, hence, low level of prices will support economic growth and reduce oil import bill in importing countries and dampen economic growth and reduce oil export revenue in exporting countries.
