Energy security has been one of the highest priorities for all economies in the Asia-Pacific Economic Cooperation (APEC) region. In order to gauge the supply security risk for oil and gas, this study established six indicators based on PESTLE analysis – political, economic, social, technical, legal and environmental. A total of 59 sub-indicators were assigned in these indicators in order to establish the index. The study made further analysis on major import sources for crude oil, petroleum products and natural gas. The key findings of the indexation are divided into two energy resources – oil and gas.
