This is the most market friendly outcome and could see sterling extend its gains. A high Tory majority would mean reduced uncertainty over Brexit and the transition period. The pound could advance towards 1.35 in the near term.
The pound could advance but gains would be limited. Whilst the Withdrawal Agreement would be passed through Parliament concerns would arise over whether an extension to the transition period would be agreed in 2020. Looking beyond the election result, historically the pound has underperformed in small majority governments.
The prospect of Brexit being done early next year would evaporate and the pound would price in further Brexit uncertainty taking it back to 1.26
4. Labour Small Majority
This is the least market friendly outcome given market concerns over Labour’s nationalisation and fiscal policies, in addition to further Brexit uncertainty. The market is not pricing in a Labour win.
Will we see an impact on other G10 currencies?
If there is any spill over we expect it to be short lived given that Brexit is a domestic event. Post the Brexit referendum, the US dollar and Japanese yen outperformed, whilst the euro came under pressure.
