Abstract
The ‘crude oil price’ has been one of the integral components of rising globalization. This paper delves into the static and dynamic multifractal analysis of daily prices of Brent crude oil for the period of 33 years (1987–2020) using the multifractal detrended fluctuation analysis. We discuss the results and limitations of the static multifractal analysis of historical data of crude oil. The crude oil market contains much more complexity in its dynamics that needs to be examined to draw inferences. These are important for socio-economic and political policy formulation at the global level. Thus the temporal multifractal analysis of historical data of crude oil is performed to understand such complexity. Further, the effect of extreme events on the multifractal properties of the crude oil market is also investigated. It is shown that multifractal spectra evolve through different shapes with time and the multifractal asymmetry coefficient can be used as an indicator in the detection of extreme events.
