The Financial Times is running a series right now on the future of the City of London. In their latest article, they looked at "How London grew into a financial powerhouse," while at the same time comparing it to other global financial centers. It's interesting to see how much of a banner year this was for companies going public. Companies listing on the Nasdaq and the NYSE raised a record $150 billion in 2020. This is compared to about $6 billion raised in London (both the London Stock Exchange and AIM). But what I really want to draw your attention to are the below maps from FT showing the clustering of banks, hedge funds, asset managers, insurers, and professional services firms in London. This is what urban agglomeration economies look like.
