In order to find out which industries will be particularly affected, this study examines data from the World Input-Output Database (WIOD) on the exchange of inputs between 56 industries in the UK and the EU on the one hand, and between the United Kingdom and Germany on the other. The majority of inputs exported from the UK to the EU are provided by service industries. In the other direction, the picture looks very different. Eight of the ten EU industries with the largest volume of intermediate products and services exported to the UK are in manufacturing. The inverse coefficients for the exchange of inputs between Germany and the UK are calculated for each sector. This shows how dense the network of links between these industries is. The value regarding German inputs sourced from Britain is the highest for other transport equipment, followed by coke and refined petroleum products and the basic metal industry. In terms of British inputs sourced from Germany, the inverse coefficients suggest that the industries most affected are automotive and chemicals.
