The OPEC published its World Oil Outlook 2015 (WOO) in late December, which struck a much more pessimistic note on the state of oil markets than in the past. On the one hand, OPEC does not see oil prices returning to triple-digit territory within the next 25 years, a strikingly bearish conclusion. The group expects oil prices to rise by an average of about $5 per year over the course of this decade, only reaching $80 per barrel in 2020. From there, it sees oil prices rising slowly, hitting $95 per barrel in 2040.
Long-term projections are notoriously inaccurate, and oil prices are impossible to predict only a few years out, let alone a few decades from now. Priced modeling involves an array of variables, and slight alterations in certain assumptions--such as global GDP or the pace of population growth – can lead to dramatically different conclusions. So the estimates should be taken only as a reference case rather than a serious attempt at predicting crude prices in 25 years. Nevertheless, the conclusion suggests that OPEC believes there will be adequate supply for quite a long time, enough to prevent a return the price spikes seen in recent years.
