The report is the opening salvo in the campaign from a public institution and as such will always carry some weight. However, it is quite a different beast from the BoE’s intervention in the Scottish referendum and is unlikely to have the same impact. That said, on balance it seems to slightly favour the Remain side by giving a clear endorsement that the single market has been good for the UK economy and that on balance the UK has had influence over regulation. But it is worth considering that, if this is the BoE’s only intervention, it is far from categorical and is very narrow in its focus. In the longer term this could shift the balance back towards the Leave side. In the end, it’s hard to see this report jumping into people’s minds when they go to vote in a year or two’s time in the EU referendum. In that sense it might have less impact than some will have expected or hoped.
