For an economist, it’s rare that events occur enabling us to directly test our economic theories and assess them against outcomes. Britain’s Brexit vote last year was one such moment. As the formal Article 50 process for EU withdrawal begins today, it’s worth re-examining the consensus view on what a “Leave” vote would mean. Those warning of impending doom today are many of the same people who predicted a decision to exit would bring immediate economic slowdown.
The Economists for Brexit group of which I was a founding member was busy refuting anti-Brexit reports pre-referendum. Britain’s Treasury led the way, claiming GDP would be 6.2 per cent smaller after 15 years if Britain exited the EU and single market (replaced with an EU-UK bilateral trade deal, as Prime Minister Theresa May now desires). Importantly, they forecast the mere act of voting to leave would trigger an immediate 4-quarter recession with 500,000 people losing jobs, higher inflation and lower house prices. There would be a “profound economic shock.” The IMF warned that a path towards leaving the single market would mean a recession in 2017. The OECD predicted a “major negative shock.” An Economists for Remain letter signed by 12 Nobel Laureates likewise said “a recession causing job losses will become significantly more likely.”
Yet the UK economy has proven robust. Immediate financial market turbulence following the unexpected vote quickly subsided. Far from contracting at the Treasury’s forecast 0.4 per cent annualized rate, the economy is currently growing at 2.8 per cent per year. The employment rate for 16 to 64 year olds is at its highest ever level, 74.6 percent, with unemployment at just 4.7 percent. House prices are currently increasing at 6.2 per cent per year. Annual broad money growth was 6.6 percent in January – suggesting robust nominal GDP growth through 2017. Even after Theresa May pledged to leave the single market and customs union, forecasters were revising growth estimates upwards for 2017.
The economic consensus did forecast correctly the pound’s fall on a trade-weighted index (around 13 percent decline), as did the Economists for Brexit analysis. This will raise the UK inflation rate. But even the recent uptick in inflation to 2.3 percent is in part driven by increasing commodity prices affecting U.S. and German inflation rates too. The flipside has been strong export order books, highlighted by the Confederation of British Industry’s buoyant survey last week. What happens to the pound in the longer term of course depends on the economic fundamentals, but what is clear is that so far the doom-mongers have been wrong on the macroeconomic impact overall.
