How Brexit has already cost London’s financial hub billions
- Three years and three prime ministers since the Brexit referendum, fraught negotiations and political turmoil have sapped confidence in the industry
- This, in turn, has put financial firms on the verge of moving thousands of jobs – and possibly £1 trillion pounds ($1.24 trillion) of assets – out of the city

Three years and three prime ministers since the vote, fraught negotiations and political turmoil have sapped confidence in the industry, putting financial firms on the verge of moving thousands of jobs – and possibly £1 trillion pounds ($1.24 trillion) of assets – out of London.
There are signs of resilience: London has extended its lead in foreign-exchange interest-rate derivatives trading since the referendum, and the city remains the only European financial hub in a ranking of the world’s top 10 by commercial think tank and consultancy Z/Yen.
Still, Catherine McGuinness, chairwoman of the policy and resources committee at the City of London Corporation, which oversees the financial district, said there was little doubt that the Brexit process was hurting financial services, which account for 11 per cent of tax receipts in the UK.
“The UK does need to be very careful how it treats its services sector, because it could lose more than it needs to if it’s not,” McGuinness said in an interview. “Of course we will lose some EU-facing business,” she said adding that she is “very concerned about the shorter term, especially if we have a no-deal exit”.
