Estimated Costs of Leaving an Economic Union (Brexit)

The UK’s ruling government’s very own study suggests Brexit will cost the UK between $80-$300 billion (2.5-9.3% of GDP) per year (!).  A study commissioned by the “People’s Vote campaign” (which seeks a second Brexit referendum), was conducted by the independent National Institute of Economic and Social Research (NIESR), found that the most likely cost to the UK would be 3.9% of GDP or $125 billion. The House of Commons Treasury Committee requested that the Bank of England published an analysis of the effects of Brexit; the Bank of England Report published today suggested the impact could exceed $300 billion with -10% of GDP per year
