Will Brexit speed a seismic shift in UK trade patterns?

Abstract

The UK's trade pattern has shifted significantly away from the EU since the 1990s. Our analysis suggests that this shift will continue in the decades to come, with the EU share in UK goods exports potentially slipping to around 35% by 2035. Shifts in relative prices from moves in tariff and especially non‐tariff barriers could lower the share further. Over 60% of UK goods exports went to the EU in the late 1990s but this has fallen to around 45%. Slow EU growth is partly to blame, with UK exports to the EU barely expanding since 2007. But our analysis also shows that a 1% rise in EU GDP leads to only around half the rise in UK exports to the EU that a 1% rise in GDP in the rest of the world induces in UK exports to non‐EU countries. Based on our findings and OE forecasts of long‐term growth in the EU and the world, the EU share of UK goods exports could fall to 37% by 2035 and around 30% by 2050 – back to its 1960 level. The share of services exports to the EU has held up better but is lower than for goods, at around 40%. Weakening growth of UK exports to the EU has taken place despite the development of the EU single market since the early 1990s. Indeed, based on our projections UK goods exports to the single market could drop below 5% of UK GDP by 2050. These projections make no allowance for Brexit effects, but the declining importance of exports to the EU single market could colour prospective Brexit negotiations. Simple income‐based projections of potential country shares in future UK exports suggest a further swing towards emerging countries (EM) in the decades ahead, especially China and India. Exports to EM could approach 40% of the total by 2035. A shift in the pattern of trade preferences and restrictions faced by the UK post‐Brexit could spark even larger shifts in the structure of UK exports.
