The oil supply summary monthly report provides analysis on short term global oil supply through 2017. The written document is accompanied by a related excel data download. World liquids supply is estimated to have fallen by 0.5 million b/d to 95.2 million b/d in May 2016 compared with April 2016. Key factors include lower production from Canada after the recent wildfires and an increase in infrastructure attacks in Nigeria. These losses have been partially offset by the return of Iranian volumes.
