Which of the following is NOT usually a function of a depository intermediary?

Depository intermediaries, such as banks and credit unions, typically engage in a variety of functions to facilitate financial transactions and manage funds. Accepting deposits is a fundamental function, as these institutions collect savings from individuals and businesses to provide a safe place for money. Additionally, they provide loans to consumers and businesses, using the funds from deposits to finance various lending activities. Offering fixed investment strategies is also common, as these institutions may provide investment products that promote stable returns for customers.

However, paying high variable interest rates on all accounts does not align with the standard operating practices of depository intermediaries. These institutions usually offer competitive, but relatively stable, interest rates that are influenced by market conditions and their own cost of funding. A focus on paying high variable interest rates would typically not be sustainable or prudent for these intermediaries, as it could lead to volatility in their funding and operational stability. Maintaining a balanced approach to interest rates allows them to manage their resources effectively while still serving their customers' needs. Therefore, the option that does not usually represent a function of a depository intermediary is linked to an expectation that could undermine their financial health and stability.
