The international system has metamorphosed into a global village. Therefore, we can talk about globalization-free flow of goods and services, resulting in a global economy. The need for self-preservation by sovereign states and the pursuit of their foreign policy from external threats such as terrorism and domination by other states through the instrument of War have led to the institutionalization of global security. Covid-19 pandemic unlike any other viral outbreak has not only threatened the free flow of trade and people around the world through the global economic recession but has also shaken the very roots of global security especially from the dimensions of human security. This study, global economy during covid-19 pandemic and its impact on the global security seeks to expose the way(s) in which covid-19 has influenced global security using the following objectives; to examine the effect of covid-19 on the global economy, and to determine the impacts of global economy on global security during the covid-19 pandemic era. A major finding of this study shows that the global economy during covid-19 is in recession and this has affected global security by endangering humans in terms of food, job, exposure to human rights violations and lack of cooperation among world governments with threats to withdraw sponsorship from WHO, a major largest organization fighting the covid-19 disease globally. The study ends by recommending cooperation by world leaders and more sponsorship and donations to WHO, aiding them to use their instrumentality to fight covid-19.
