The macroeconomic stability of United Kingdom after Brexit
The macroeconomic stability of United Kingdom after Brexit

Summary/Abstract: Motivation: The United Kingdom has triggered Article 50 of the Lisbon Treaty on 29th March 2017 and formally has begun Britain’s exit from the EU. The Withdrawal Agreement entered into force on 1 February 2020. The very announcement of Brexit aroused many concerns and uncertainty. The Withdrawal has taken place in an orderly manner, and the UK and the EU remain in close partnership with new agreements. Such a significant institutional change also may affect the economy and indirectly macroeconomic stability. Aim: This research aims to identify and assess the changes in macroeconomic stability in the United Kingdom, from the year before the Brexit referendum to the first year outside the EU, i.e. in 2015–2021. Results: The method used in the study is a comparative analysis that employs a macroeconomic stabilization pentagon model (MSP). The macroeconomic stabilization pentagon is based on the GDP growth rate, the unemployment rate, the inflation rate, the budget balance, and the current account balance. The time range of research is 2015–2021. The MSP indicators for the United Kingdom and EU-27 are compared. In the period 2015–2018, i.e. during the uncertainty as to the results of the Withdrawal Agreement negotiation, the MSP index fluctuates slightly, which we interpret as very small changes in macroeconomic stability. The UK’s macroeconomic stability has fallen dramatically in 2020, the first year out of the EU. It is worth emphasizing that the UK’s macroeconomic stability was lower than EU-27 one throughout the period studied.
