Who can utilize a sweep structure?

A sweep structure can be utilized by both corporations and individual retail clients, although corporations are the primary users. A sweep account automatically transfers amounts that exceed a certain level into a higher interest-bearing account, helping clients manage their cash effectively.

Large corporations often use sweep accounts to maximize the interest income on their idle cash, but individual retail clients can also take advantage of sweep structures, especially those who maintain higher balances in their accounts. This flexibility allows a diverse range of clients to optimize their cash management strategies, making the answer encompassing both retail clients occasionally and corporations as the most accurate.

The other options limit the use of sweep structures to specific groups or account types, which does not reflect the broader applicability of these accounts in financial management.
