The GSADF test is used to determine whether crude oil prices have experienced multiple bubbles, with results indicating the existence of bubbles coinciding with specific crises. Factors leading to oil price bubbles include global economic expansion, imbalances in supply and demand, dollar depreciation, excess supply, etc.
The Generalized Supremum Augmented Dickey-Fuller (GSADF) test is employed to conclude whether crude oil price (OP) experiences multiple bubbles. The technique has distinctions to detect multiple bubbles along with its beginning and ending point. Oil is extremely significant due to its strategic position and several factors influence OP. The outcomes display the existence of bubbles which imply that OP deviates three times. This indicates the beginning and termination of bubbles coincide with a particular crisis. The expansion of the world economy, the mismatch between demand-supply of oil, dollar depreciation, excess supply by Organization of the Petroleum Exporting Countries, shale oil production of the U.S., and low demand by the emerging economies are the leading factors of OP bubbles. The main contributions are the investigation of the OP bubble, its determinants and the different technique of GSADF to detect OP bubbles. Moreover, the greater economic certainty and political stability ensure a smooth supply of OP can lessen unexpected fluctuation. The symmetric information can minimize market speculation, improve market efficiency, help investors make reasonable investment decisions, and minimize potential price risks.
