This report is based on an analysis that began in early 2021 to research the impacts of the pandemic on oil and gas security in the APEC region. Some of the largest impacts to global energy supply and demand occurred in the APEC region, and the persistence of the pandemic means that the long-term effects remain uncertain. Prior to the pandemic, oil and gas markets were experiencing changing dynamics and challenges, and COVID-19 brought new challenges to oil and gas security and the resiliency of the APEC energy system. As the largest oil and gas consuming region in the world, APEC economies need to understand these dynamics to better prepare for their energy futures. This study examines the changes to oil and gas markets brought on by the COVID-19 pandemic and provides insights and implications for APEC economies as they adapt their energy policies to a post-pandemic world.
