General Election: How would the parties' plans impact the outlook?

Abstract

Our modelling suggests that, based upon the three main parties’ economic and fiscal plans, the outcome of the General Election would have a modest, but not immaterial, impact on the UK's economic and fiscal outlook. The Liberal Democrat plans would deliver the strongest GDP growth, followed by Labour, but both would also involve higher debt servicing costs and a higher level of government debt than the plans of the Conservatives. In our view these premiums on debt and borrowing costs are so small that it is very difficult to argue that the UK should pursue a more austere fiscal policy and reject the opportunity of stronger growth. But with the latest opinion polls suggesting that it is likely that the next government will be either a minority administration, or a coalition consisting of three or more parties, it is most likely that we will ultimately see some combination of the main parties' plans enacted. The experience of 2010 suggests that such political uncertainty could mean that we see several bouts of market nervousness between now and May 7th, particularly in equity markets. However, such turbulence is likely to be short‐lived, providing that the resulting government is perceived to be strong and durable. Even a multi‐party coalition may not be such a bad thing, particularly if it watered down the more contentious policies of the main parties. The worst‐case scenario would be a weak minority government which is both unable to pass any meaningful legislation and unable to seek a fresh mandate. Such a scenario could seriously undermine confidence amongst investors and firms.
