The UK government published a White Paper on 12 July with an outline of its preferred relationship with the EU. Both sides are looking to reach an agreement by October 2018 to allow the European Parliament to approve the withdrawal agreement and ensure that a deal is in place ahead of Brexit on 29 March 2019. In it the government has prioritised a free trade area for goods trade and an ambitious arrangement for services trade while taking back control of immigration and budgetary contributions. In our view the government will have to make significant concessions to the EU.
As before, the central forecast has been conditioned on a ‘soft’ Brexit assumption where the UK achieves close to full access to the EU market for goods and services. If instead of this soft Brexit scenario we assume that the government achieves the somewhat more restrictive White Paper proposals, the output loss will amount to £500 per person per year over time compared with the soft Brexit scenario. The loss would be around £800 under a ‘no deal’ Brexit. These estimates do not include the likely impact on productivity which could, on some estimates, double the size of the losses.
The Bank of England will take account of this uncertainty when setting policy and also weigh the consequences of ‘getting it wrong’. With the economy growing in line with potential, we recommend that the MPC raises Bank Rate gradually but also stand ready to move in either direction should circumstances change. The committee should emphasise the uncertainty (rather than the certainty) of its future policy stance in its communications and its willingness to reverse its decisions.
The pressure to end fiscal consolidation is high. The government faces pressures to increase spending in a number of areas to maintain the quality of public services. Consistent with our view, the government has very recently promised new spending on the NHS and partially lifted the wage cap on public sector employees. Consistent with that, our central forecast assumes that government spending (as a share of GDP) will not fall as forecast by the OBR. As a result, the budget deficit remains close to 2 per cent of GDP over the next five years instead of the OBR's forecast of 1 per cent.
