The pandemic, which emerged in Wuhan, China in December 2019, has deeply affected the economies of countries at the global level. This study aims to investigate the impact of the Covid-19 pandemic on oil prices. The model is built on two separate periods as the shock period (23 January 2020- 31 December 2020) and the vaccination period (4 January 2021- 31 August 2021). The study was developed on the basis of Salisu, Ebuh and Usman’s (2020) study examining the causality relationship between oil prices and stock returns in the pre- and post-pandemic period of Covid-19. In the study, Johansen Cointegration test was applied using oil prices (LOIL), global daily confirmed Covid-19 case numbers (LCOV) and US dollar index (LDXY) variables. It has been seen that the series have unit roots and are cointegrated in the long run. FMOLS and CCR tests were applied to determine the degree and direction of the long-term effect among the variables. In conclusion, the effect of the pandemic on oil prices seems to have a more moderate negative effect in the vaccination period compared to the shock period. Countries should accelerate their vaccination efforts to reduce the effects of the pandemic.
