To answer the question directly, probably not. London has many things going for it that other European cities, such as Frankfurt, Paris, Rome, and Amsterdam do not. First, English can loosely be classified as the world’s language. The vast majority of the Internet’s content is published in English and many of the world’s most prominent economic centers – e.g., New York, San Francisco Bay Area, London – all are located in English-speaking jurisdictions. Frankfurt, Paris, Rome, and Amsterdam (among others) also lack the sheer population and general building infrastructure to accommodate a huge influx of financial employees. London is several times the size of each of these cities – nearly 10x the population of both Frankfurt and Amsterdam, 4x the population of Paris, and 3x-4x the population of Rome. An influx of hundreds of thousands of financial services employees out of London into a dedicated new economic center of the EU, or even among a few cities, would put massive strains on building needs and would be a very slow process that would require several years of planning.In short, London’s status as the financial capital of Europe is not under any threat in the short-term and would take many years before financial service employees could realistically more evenly disperse throughout the EU.
