The functions of investment banks are typically less well understood than those of retail or “high street” banks. Two key functions are: helping large organisations, such as companies and government agencies, to raise finance through capital markets; and trading in a wide range of financial instruments, mainly on behalf of a bank’s clients, which include large corporations, other banks, insurance companies, pension funds and hedge funds. Both of these functions can help financial markets to function effectively and serve the real economy.
However, investment banks can also be a source of risk to the financial system. Drawing on an internationally agreed framework for assessing systemic risks, this article highlights the following factors:
Many of these risks crystallised during the recent global financial crisis. At that time, some of the largest global investment banks were either taken over, bailed out using public funds, or forced to declare bankruptcy after facing distress.
A number of regulatory initiatives globally have been implemented since the onset of the global financial crisis to mitigate these risks, and to build a safer, more resilient financial system that continues to serve the real economy. Some of these key initiatives are discussed in the article. The Bank of England has a key role to play in working with other regulatory bodies globally to fully implement these initiatives and ensure that investment banking activities are conducted in a way that is safe and sound. The agreement of these standards for banks is substantially complete, but it is important to ensure that they are implemented fully, to monitor new risks, build mutual trust and further facilitate international co-operation.
