Brexit and Uncertainty : Insights from the Decision Maker Panel

The UK's decision to leave the EU in the 2016 referendum created substantial uncertainty for UK businesses. The nature of this uncertainty is different from that of a typical uncertainty shock because of its length, breadth and political complexity. Consequently, a new firm-level survey, the Decision Maker Panel (DMP), was created to investigate this, finding three key results. First, Brexit was reported to be one of the top three sources of uncertainty for around 40% of UK businesses in the two years after the vote in June 2016 referendum. This proportion increased further in Autumn 2018. Hence, Brexit provided both a major and persistent uncertainty shock.
