The week kicked off with a warning from the British Bankers' Association (BBA) that the big banks are preparing to more out of London and the UK over Brexit worries.
Potential impacts on the financial services sector has been well publicised and BBA boss Anthony Brown said banking - the UK's biggest export industry - was probably more affected than any other sector.
Passporting rights
It all centres around the prospect of losing passporting rights, which allows the sector to trade within the EU block, due to the UK being in the single market.
A 'hard' Brexit, which is where the government is apparently leaning, sees the UK leave the single market.
The government has been publically making noises reiterating the importance of the financial industry but, reportedly, there are officials saying any Brexit deal will have to work for the UK as a whole - not just the City.
From an investment point of view, the banks have had a torrid time this year, which doesn't look like changing any time soon.
It's ceratinly been a mixed bag this week after statements from Barclays (LON:BARC) and RBS (LON:BARC), led to the biggest Footsie riser and loser on the day.. in that order
Michael Heswon, at CMC Markets, said earlier in the week: "The sharp fall in the share prices of the UK banks in the aftermath of the Brexit vote has shown little signs of being reversed, and the outlook probably won’t have improved too much given the cut in UK interest rates that followed in August which flattened the UK yield curve even further."
He highlights some evidence in July that US banks were seeing a pickup in profits, on a slowly improving US economy, however in Europe the outlook is "nowhere near as optimistic, as bad loans and negative rates hollow out the prospects of any sort of profitability", he suggested.
Taking toll on floats
Meanwhile, the EU referendum has taken its toll on London’s IPO (initial public offering) market in 2016 and the value of companies listing has fallen to its lowest level in four years, it emerged this week.
On Thursday, banking software firm Misys became the latest to ditch plans to return to the stock market, blaming choppy conditions.
Just 41 floats have taken place in the first nine months of 2016, lowest level since 2012 and new listings worth £948mln joined the main market and AIM in the third quarter, which was down 42% year on year
Colin Hughes of Henderson Opportunities Trust, noted: "It’s actually surprising activity was not even quieter ahead of the vote, and that perhaps reflects the unexpected leave result in the referendum.
"It’s not necessarily bad for investors in the short term – it means it’s a buyers’ market: new listings have to compete for investor cash and that means keener prices."
UK growth slowing
GDP figures on Thursday showed the UK economy growth at dropping to 0.5%, down from 0.7% in the June quarter. It was a slowdown but economists had expected worse - at 0.3%.
It was also a beat on the latest forecast from the Bank of England, which predicted that third quarter growth would come in at 0.1 per cent, but economists still see potential weakness in the medium and long term, notably next year when Article 50 is triggered, which may hit invetsment, and rising inflation hitting wages.
Tony Blair intervenes
Former Labour Prime Minister Tony Blair has also joined the debate. He reckons people should be given another chance to have their say on leaving when it becomes clear what a Brexit will actually look like
That could be through a vote in Parliament, an election or a second referendum, he said
