Evidence of the UK’s economic performance since the EU Referendum is clear: GDP growth has slowed down, productivity has suffered, the pound has depreciated and purchasing power has gone down, and investments have declined, according to analysis by Josh De Lyon and Swati Dhingra.
The impact of the Brexit vote can now begin to be evaluated with greater accuracy than previous forecasts, thanks to the emergence of new data. [...]
Firstly, the UK’s GDP growth has slowed down. In broad macroeconomic terms, GDP growth in the UK has been low but remained positive since the referendum. Relative to G7 countries, however, the UK has slipped from having the highest growth rate in the G7 before the vote, to the lowest now (OBR 2018). This suggests GDP growth has held up likely as a result of international trends, but it is showing weakening internal trends.
Productivity has also suffered. The negative signs of economic health are confirmed by the outcomes in productivity stagnation. Output per worker has continued to be stagnant since the referendum. Worryingly, the gap between output per worker in OECD countries and the UK has widened since the referendum.
The sterling has depreciated and increased costs. The single biggest economic shock immediately after the referendum has been an unprecedented drop in the value of the pound. On referendum night, the pound fell from a high of $1.50 to $1.33. This is the single biggest drop in the daily exchange rate since the 1970s among the four major currencies of the world. The sterling depreciation was expected by some to spark an export boom, but this has not happened. Relative to G7 countries, the value of exports from the UK have not grown faster, as shown in Graph 2. Industry data confirm this. For example, car exports decreased to both EU and non-EU countries in the three months to December 2018. There is also some evidence to suggest that exports might have been curtailed as a result of the trade policy uncertainty arising from the Brexit vote (Crowley et al. 2018, Graziano et al. 2018).
The value of imports into the UK has been broadly slower than in the G7 countries, as shown in Graph 3. But the rise in the price of imports, as a result of the sterling depreciation, has raised the costs of intermediate inputs, which are needed by businesses. Sectors more exposed to the overnight sterling depreciation, through their existing global supply chain structure, have seen higher increases in import costs. These industries show lower wage growth and reduced training opportunities since the vote to leave the EU (Costa, Dhingra, Machin 2019 ). The fallout of higher import costs has to a degree fallen on UK workers in terms of lower earnings now and in the future through fewer skill development opportunities.
Purchasing power has gone down. On average, real wages have been flat since the referendum. Nominal wages have risen, but below the previous 2% norm (ONS 2018). Consumer prices have risen to reduce real wages. Inflation rose sharply after the referendum and remained high till recently. In January 2019, it dropped below 2% for the first time since the referendum but is still at 1.8%. Growth in food prices, which was as high as 4.4% following the referendum, has returned to low levels of inflation (De Lyon et al. 2017). Compared to G7 countries, consumer price inflation continues to be higher but has fallen closer, as shown in Graph 3. Estimates suggest that aggregate inflation increased by 1.7 percentage points or £7.74 per week as a result of the referendum (Breinlich et al. 2017).
Finally, both inward and outward foreign direct investment (FDI) have dropped since the referendum. The most recent FDIdata available are for 2017. The value of the UK’s inward FDI position increased by £149.2 billion to £1,336.5 billion in 2017 from 2016, while the outward position increased by £38.7 billion to £1,313.3 billion over the same period; this led to a slight negative net FDI investment position of £23.2 billion, the first time that this has been recorded (ONS 2017). Compared to selected control groups of similar developed countries, estimates suggest that the Brexit referendum result on inward FDI is a drop of 11 to 19 per cent compared to the counterfactual in which the referendum did not happen (Serwicka and Tamberi 2018, Breinlich, Leromain, Novy, Sampson 2019). On outward investments, estimates suggest a 12% increase (or £8.3 billion till 2018Q3) in the number of new investments made by UK firms in European Union (EU) countries.
Overall, the real economy shows signs of productivity and real wage stagnation, which has taken the UK much lower than other high-income countries since the Brexit referendum. Financial outcomes have shown mixed results, with the sterling down but the FTSE 250 continuing to perform relatively well since the referendum (London Stock Exchange 2019).
