Rejoining EU Customs Union Won't Fix Brexit Damage, Research Finds

The Brexit Trade Damage
Brexit has depressed UK exports to the EU by 12%, and rejoining the customs union would undo only a fraction of the damage, research shared with the Guardian shows.
UK Export Decline
A decade on from the referendum, economists John Springford and Anton Spisak, of the Centre for European Reform, have found that services sector exports to the EU are 7% lower than they would have been if the UK had remained in the EU, and goods exports are 16% lower.
The Data Analysis
UK exports to the EU have declined by 12% due to Brexit.
Services sector exports to the EU are 7% lower.
Goods exports to the EU are 16% lower.
The Impact Analysis
The hardest-hit sectors have been travel, finance and insurance, chemicals and pharmaceuticals, and agrifood. The research suggests that the overwhelming majority of the impact – 10% of the total 12% decline in exports – is accounted for by leaving the single market.
The Prediction
Rejoining the customs union alone would have a modest impact, eliminating the need for UK firms to comply with complex “rules of origin” to qualify for tariff-free trade. However, it would not benefit the hard-hit services sector, and the UK would lose the opportunity to pursue trade deals with non-EU countries.
