Any disruption in cross-border data flows would, therefore, be economically costly to both the UK and the EU. Taking EU-US data flows as a comparator, external estimates suggest that if cross-border data flows between the EU and the US were seriously disrupted, the EU’s GDP could reduce by between 0.8 and 1.3 %. Therefore, placing restrictions on cross-border data flows could harm both the economies of the countries implementing these policies, as well as others in the global economy…
