What does the term 'two-way sweep' primarily refer to?

The term 'two-way sweep' primarily refers to the automated movement of funds between accounts at designated intervals. This process is designed to optimize cash management by ensuring that excess funds in one account are efficiently transferred to another account where they can earn interest or be utilized for operational needs. Conversely, if the balance of a funding account falls below a specified threshold, funds can be automatically transferred back to maintain required levels.

This method enhances liquidity management and minimizes idle cash, allowing organizations to maximize the return on their available funds. By automating these transfers, businesses can save time and reduce manual errors, ensuring that their cash flow remains optimal without requiring constant oversight.

The other options do not accurately represent the primary function of a two-way sweep. High-interest investments and manual fund transfers do not convey the automatic, systematic nature of this process, and using multiple currencies pertains to a different context in financial transactions.
