A universal bank participates in many kinds of banking activities and is both a commercial bank and an investment bank as well as providing other financial services such as insurance. These are also called full-service financial firms, although there can also be full-service investment banks which provide asset management, trading, and underwriting.
The concept is most relevant in the United Kingdom and the United States, where historically there was a distinction drawn between pure investment banks and commercial banks. In the US, this was a result of the Glass–Steagall Act of 1933. In both countries, however, the regulatory barrier to the combination of investment banks and commercial banks has largely been removed, and a number of universal banks have emerged in both jurisdictions. However, at least until the global financial crisis of 2008, there remained a number of large, pure investment banks.
