This research paper aims to explore whether the predictions made before Brexit on how it would impact the EUs economy have been accurate. My main question to conduct this research is What are the main economic implications of Brexit for the European Union. The research was conducted by analysing existing literature, economic forecasts and post-Brexit data in order to successfully carry out the comparison. The resources used have been extracted from official sources such as the European Commission, European Central Bank, International Monetary Fund and others combined with previous research studies conducted by specialists. Findings suggest that Brexit has led to economic disruptions. EU countries have experienced increased costs when trading with the UK and disruptions in supply chains. Member states have not been affected equally, some have highly benefited from the shift in FDI and relocation of services and others have been subject to loss of household income due to the end of free movement of people.BrexitEuropean Union (EU)United Kingdom (UK)TradeEU BudgetForeign Direct Investment (FDI)Economic impactThesis
