Top 20 largest UK financial companies 2021

Top UK financial companies

The financial sector is the backbone of the British economy, critical support for all business operations. Banks, insurance, and financial services companies enable vital financial activities, payment or saving solutions, credit or capital availability, risk mitigation, and financial information accuracy.

The top British financial companies are involved in a diverse range of operations all along with the flows of money and capital in the economic cycle. Delivering high value-added financial products and services that provide large returns on investments, British financial companies also naturally face very stiff competition from both national and foreign actors of the financial sector.

The confrontation between the financial services companies, multiple types of banks, insurance companies, and broader financial actors who struggle for market share creates a shifting environment. Financial companies specialize, diversify and acquire others to reach higher returns, reduce their costs, better hedge their risks, and find safer investments.

However, besides the competition through the different financial verticals, and the confusion in European financial affairs brought by Brexit, a new, critical, and major threat facing the financial companies is the disruption of traditional by upcoming startups. Among the largest UK startups, some of the world’s top FinTech startups, and InsurTech startups are very serious menaces to traditional British financial companies.

As these startups reach a large portion of the market, they gain financial power and leverage from their customer base. Their power is generally recognized when they reached the status of “unicorn”,  that is to say, a startup with a valuation above 1 billion dollars. Since these unicorns grow very fast, they bring along significant changes in the financial landscape and weigh heavily in the competition thanks to their envied up-and-coming status.

For now, the largest financial companies are still powerhouses of the UK economy, and, in spite of new challenges, they will most probably stay in this position in the coming years. Thanks to the traditional power of the United Kingdom in global financial affairs, British financial companies will continue to fight domestically, and leverage the advantage of their century-old expertise and networks to hold their ground and keep expanding their footprint in the rest of the world.
