GDP to be 3% lower in the longer term than it would have been had the UK stayed in the EU, new NIESR report reveals
A new NIESR report out today, ‘The economic impact on the United Kingdom of a customs union deal with the European Union’, by Dr Arno Hantzsche and Dr Garry Young, provides estimates of the economic impact on the United Kingdom of leaving the EU to form a UK-EU customs union. Main points are:
- GDP in the longer term is estimated to be around 3 per cent lower in a customs union than it would have been had the UK stayed in the EU. This is equivalent to a loss of over 2 per cent in GDP per head, worth around £800 per person per annum to people in the UK.
- The lower level of GDP would mainly be a consequence of higher barriers to trade in services as a result of being outside of the European single market.
- A smaller economy would generate less income with which to pay for public services. The authors estimate that there would be an effective revenue shortfall of around £13 billion a year that would need to be raised either by additional borrowing, higher taxes or reduced public spending.
- GDP in each region of the United Kingdom would be reduced by a broadly similar amount, ranging from 2½ per cent to 4 per cent, relative to what it would have been with continued EU membership.
The estimates presented represent the Institute’s considered view of the economic impact on the United Kingdom of a customs union deal with the European Union, but the estimates are uncertain as there is no historical precedent of a country leaving a major trading bloc such as the EU.
Garry Young, Director of Macromodelling and Forecasting, said: ‘Leaving the EU for a customs union will make it more costly for the UK to trade with a large market on our doorstep, particularly in services which make up 80 per cent of our economy. This inevitably will have economic costs, with widespread implications. We estimate that all regions will be adversely affected and that there will be fewer resources available to pay for public services’.

This report has been prepared for the People’s Vote campaign by the National Institute of Economic and Social Research (NIESR) and been undertaken solely to provide public information.
NIESR is Britain’s longest established independent research institute, founded in 1938. It has no institutional position on how or whether the UK should exit the EU.
NIESR receives no core funding from any source, and is independent of any policy or party political affiliation. We undertake projects for external organisations only on the basis that the Institute has full control over content, and we seek to ensure that all such work is publicly available as is the source of any funding we receive.
The economic models which the Institute maintains can be applied to a wide range of policy questions. We seek and do make them available to a wide range of bodies. As a charitable body, we believe that applying our facilities to real life issues is an important element in our educational and public benefit functions. Although our analysis helps to estimate the consequences of specific policy actions, we do not undertake it with the intention of endorsing any specific approach, and our conclusions should not be taken to imply affiliation of the Institute of any specific political position.
