UK Exports to EU Down 12% Post-Brexit; Customs Union Re-entry Offers Limited Relief

New research reveals that the United Kingdom's departure from the European Union has led to a significant 12% depression in UK exports to the bloc. Economists John Springford and Anton Spisak from the Centre for European Reform (CER) attribute the majority of this decline to exiting the EU's single market, rather than solely the customs union. The findings, exclusively shared with The Guardian, underscore the ongoing economic repercussions of Brexit, particularly concerning trade flows. While rejoining the EU customs union is often debated as a potential mitigation strategy, the CER research suggests such a move would only reverse a minor portion of the identified export slump. This implies that the more comprehensive economic integration offered by single market membership was the primary driver of export performance pre-Brexit. The 12% reduction in exports represents a tangible economic cost for UK businesses reliant on EU trade. This contraction in trade volume can impact various sectors, potentially leading to reduced investment, job losses, and diminished overall economic growth. The analysis contributes to the broader understanding of Brexit's long-term economic implications, moving beyond initial transition impacts to quantify persistent structural changes. As political discussions in the UK increasingly turn towards its future relationship with the EU, particularly in the context of potential leadership contests, this research provides crucial data for policy considerations. It highlights the economic trade-offs inherent in different levels of integration with the EU, indicating that a customs union alone may not restore the previous trade dynamic. The focus on single market effects suggests that non-tariff barriers and regulatory divergence are significant contributors to the current export performance.
