Brexit Aftermath: Outlook for the UK

Brexit Aftermath: Outlook for the UK

Now that we have had some time to digest the UK’s collective decision to leave the European Union, what can we say about the prospects for the UK’s economy over the next 12 months?

Our expectation is that growth will fall to around 0% or slightly above over the next 12 months, based upon a material slowdown in business investment, some easing in consumer spending and little change in either fiscal policy or the contribution from net trade. Of course we recognize there is a lot of uncertainty to any outlook amid this politically charged atmosphere.

Also, we would expect CPI to rise to 2% by mid-2017, as the impact of weaker sterling is reflected in import prices. While there are risks around this forecast, not all of those risks are to the downside. Certainly there is scope for a more material fall in business investment or consumer spending than we are expecting, but there is also scope for some form of fiscal stimulus.

Business investment had already shown some weakness ahead of the EU referendum on 23 June, and we would expect a further slowing to a -5% to -10% annual rate over the next 12 months, in line with some of the weaker periods in the decade prior to the financial crisis. At around 10% of GDP, this will take around 0.5% to 1% off growth. Arguably harder to gauge will be the hit to consumer spending, and given that it generates around two-thirds of GDP, this will be an important determinant of the magnitude of the slowdown. Our expectation is that household consumption will slow by around 1%, which would be materially weaker than the pre-crisis period; however, we would be the first to acknowledge the risks around this forecast.

UK inflation potential

Meanwhile, thinking about the path of inflation, the 11% fall in the trade-weighted sterling index should add around 0.75% to core inflation in the next 12 months. Core inflation is currently 1.2%. The headline CPI rate will converge to the core rate as the effect of the drop in energy prices falls out of the annual number, and this should mean that headline CPI rises from its current rate of 0.3% to the 2% target by mid-2017. Again, there is substantial uncertainty about how much of the fall in sterling gets passed into the CPI, but we have used prior relationships which indicate that a 10% fall in sterling typically adds 0.5% to 0.75% to headline CPI in 12 months’ time. Crucially, this will only take CPI back to the target rate, and as such will not prove an impediment to monetary stimulus in the months ahead.

Given the weak growth profile, we expect the Bank of England to cut official rates toward (but not below) zero, and thereafter consider quantitative easing if further stimulus is deemed necessary. This should support gilts and keep sterling on the back foot.
