The French consulate publishes inflated estimates without evidence for obvious self-serving reasons, but verifiable data from the ONS is singnificantly lower than that.
Le Monde's estimate, also given in the article and based on a comparable INSEE data would make it 23rd.
Repeating ad nauseam the unsubstantiated claim that it's the 7th largest French city when all evidence suggests it doesn't even make the top 20 is not a worthwhile contribution to this discussion.
The bank my ex works at has as many traders in Paris as in London, for example, and that's fairly common.
I don't doubt there are many French traders in London - these banks shifts staff and roles around as if they're commodities. But that doesn't change the fact that Paris has a large proportion of the EU financial industry. Not as large as London, but substantial enough for Paris to be a major financial centre.
If London finance is 5 times Paris. It's enough to make it a major financial center yet it's laughable at the same time.
It's not a question if banks will move some portion of staff out of London, but how many and where they go.
London does have more than Paris, but Paris and Frankfurt are the only two other EU cities that consistently get listed amongst the top global financial centres.
What exactly that means in hard cash depends on what you want to count and how, and so the rankings vary greatly depending on who you ask.
Still no sign of movement.
Hilarious. Did you know that London is the 7th largest French city? Those people are not here for the weather. And Frexit is not off the cards either.
