The Largest Brokerage Firms in Europe in 2024

Here’s an overview of the biggest brokerage firms operating in Europe.

Unlike the more unified US market, the European retail brokerage industry is characterised by geographical fragmentation. A few big players operate across the entire continent, but most firms remain within their own national boundaries or only work in a handful of countries. This is one of the reasons why European brokerage houses are nowhere near the size of their American counterparts.

In theory, most of those national brokerages are free to accept customers across Europe, but heavy bureaucracy is often what keeps them at home. From the investor’s perspective, using a local brokerage also makes things much easier. The platform handles tax reporting for you, and you get to access local tax-advantaged investment and pension accounts – benefits rarely offered by pan-European brokers.

Despite the challenging landscape, a few big names manage to stand out. Interactive Brokers, Hargreaves Lansdown, Saxo Bank, and Nordnet are some of the largest brokerage firms operating in Europe in terms of customer base and the amount of assets they handle.

Key takeaways

  • The largest brokerage firm: The largest brokerage firm operating in Europe is Interactive Brokers, which is headquartered in the US but has a significant presence in Europe. It serves more European countries than any other brokerage, with its platform being available in 44 European countries. It has over 2.56 million client accounts and manages a total of USD 426 billion in assets globally.
  • The largest European brokerage firm: Hargreaves Lansdown, which operates exclusively in the UK, is the largest brokerage firm originating from Europe, with GBP 134.0 billion assets under management and 1.8 million customers.
  • The largest pan-European brokerage firm: Saxo Bank is the largest pan-European brokerage with roots in Europe. It’s available in most European countries, with DKK 720.7 billion in client assets and 1.01 million active customers.
  • Home is a safe haven: 85% of European retail investors only use local brokerages, which may explain the smaller scale of client accounts and assets under management relative to American brokerages.1

Largest brokerage firms in Europe, ranked

Founded in 1977, Interactive Brokers is the world’s leading international brokerage. They cater to customers from over 200 countries and provide trading services in 150 global markets across 33 countries and 27 currencies.

FAQs

What does “assets under management” mean?

Assets under management (AUM) refers to the total value of the investments a financial institution, like an online broker, manages or holds on behalf of its customers. These investments can include deposits, stocks, bonds, mutual funds, and other financial instruments. Their value also depends on the currency the broker reports in, such as dollars for US firms or euros for Euro-zone firms.

What counts as a brokerage client?

There is no fixed definition for what counts as a brokerage client. Some brokerage firms consider every user who has signed up as a client; others only consider those who are active customers or have a minimum portfolio of a specific size. As such, this metric is easily manipulated.

What is a self-directed brokerage account?

A self-directed investor is someone who makes independent decisions about their investments and executes them on their own, rather than relying on a professional. Most online brokerage accounts are self-directed. However, with this autonomy also comes full responsibility for any mistakes made.
