I am aware that investment planning and decision making has been happening but the full effects of that will be seen weeks/months after (and if) we leave the EU.
For example, in the Financial Services sector most large financial institutions already have created legal entities in EU states now and have either got or are in process of getting regulatory approval. For most, they will switch over processing to use these at points in either February or March.
For many, that means that business that used to be processed in the UK will now be shifted to EU states… in particular, for most, their non-UK business will be processed outside of the UK.
Result: less roles in UK, more in EU states for each company… a higher tax burden for UK taxpayers as the corp tax from these large companies will now be reduced as they will be taxed in EU states.
So the effect isn’t just about forward investment… it;s about reality of trading, settlement and operations.
That quite aside from the dependent industries: legal, vendors, procurement etc that is also moving parts of their business.
