Five years after the UK left the EU, cross-border financial flows between the two markets still account for a significant share of overall financial activity in both the EU and the UK.

“The interconnectedness of EU-UK financial markets”, written in partnership with New Financial, explores how the EU and the UK can deepen cooperation while jointly addressing the challenges facing Europe’s economy.

The report sets out recommendations to encourage closer collaboration between the two markets, from coordination on incoming regulations, to technical improvements, as well as non-financial measures improving the environment for cross-border business.

The world has moved on since the Brexit referendum in 2016. A more uncertain geopolitical environment is a powerful driver to rethink and strengthen relationships between friendly, industrialised, and democratic Western economies. We share the same challenges and can only master them together.
