What is the permissible use of client funds in municipal trading contexts?

• A. Client funds may be used for the dealer’s administrative expenses with client consent.
• B. Client funds may be used to collateralize the dealer's own borrowing regardless of instruction.
• C. Client funds may be commingled with the firm's general funds for convenience.
• D. Client funds must be used as instructed and only for permissible purposes; misappropriation is prohibited.

Answer: (D)

When handling client funds in municipal trading, the key rule is that those funds must be kept in trust and used only as the client directs for permissible purposes; misappropriation is strictly prohibited. This principle is what makes the described best practice: client funds must be used exactly as instructed and only for those approved purposes. Using funds to cover the dealer’s administrative expenses, even with the client’s permission, would violate the trust and is not permissible. Likewise, using client funds to back the dealer’s own borrowing—regardless of instruction—improperly puts client assets at risk and is not allowed. Commingling client funds with the firm’s general funds also breaches the required segregation and can lead to misappropriation. In short, client funds should be used only as instructed and for permitted purposes, with misappropriation and improper use strictly prohibited.
