The global oil supply monthly report provides analysis on short-term global oil supply. The written document is accompanied by a slide deck and related excel data download. At the 30 November OPEC+ Ministerial meeting, a group of producers agreed to deepen voluntary cuts for Q1 2024. This is an attempt to put a firmer floor under prices in the face of continued market concerns over demand growth. We estimate that these additional cuts will reduce Q1 2024 supply by around 580,000 b/d. Our forecast for global liquids supply is revised downward for 2024 and 2025, mainly driven by downgrades to key US NGLs plays and Iraq.
