The Treasury’s Brexit short-term impacts analysis: A bit high, a lot political

The Treasury’s analysis of the short-term impact of Brexit offers us two scenarios for the two years following the referendum: a base ‘shock’ and a ‘severe shock’ scenario. The base case means 3.6pc less economic growth in the two years following Brexit, with inflation up 2.3 percentage points and house prices down 10pc. A first thing to grasp is the connection between the scenarios in this report and those in the previous Treasury report on the longer-term impact of Brexit. In its long-term impacts, the Treasury had three scenarios, for each of three options it claimed the UK had for its trade arrangements post-Brexit (all of which were very unlikely): an ‘EEA’ option; a ‘Canada’ option (the base case); and a ‘WTO’ option. The short-term impacts ‘shock’ scenario is the one in which the economy is in transition to the Canada option over the longer-term. The ‘severe shock’ scenario goes with the WTO option. ‘But what happened to the EEA option?’ I hear you ask.
