The global oil supply monthly report provides analysis on short-term global oil supply through 2020. The written document is accompanied by a related excel data download. Our outlook for global supply remains relatively unchanged from last month, despite the backdrop of growing geopolitical risk and uncertainty in various oil producing regions. Global supply is forecast to add 1.1 million b/d in 2019, less than half of the growth seen in 2018. Why? Sanctions against Iran and Venezuela result in a combined loss of around 1.1 million b/d; OPEC cuts, led by Saudi Arabia, UAE, and Kuwait result in a fall of 0.4 million b/d; and growth is slowing in Canada, as mandated production cuts impact supply, particularly through the first half of 2019.
