Final answer:
U.S. commercial banks are traditionally prohibited from making equity investments in corporations due to regulations that aim to prevent conflicts of interest and manage risk. Foreign commercial banks often do not have these constraints and may engage in both banking and equity investments.
Step-by-step explanation:
A key difference between U.S. and foreign commercial banks pertains to their involvement in equity investments in corporations. In many other countries, banks are allowed to make direct equity investments, buying shares and actively participating in the management of the companies they invest in. However, the U.S. banking system is traditionally prohibited from making such equity investments due to regulations that separate banking from commercial activities.
This distinction stems from the Glass-Steagall Act and subsequent financial regulations, which were designed to prevent the risks associated with banks engaging in non-banking commercial activities. Conversely, foreign banks, especially in countries with universal banking systems, often operate without these restrictions, allowing them a greater scope for equity investments and involvement in the overall governance of companies.
