The term "money market" generally refers to the markets for short- term credit instruments, such as commercial paper, bankers' acceptances, negotiable certificates of deposit, repurchase agreements, and federal funds. Although not carried in the investment account, such instruments generally are handled by the investment officer. The highly liquid nature of such investments allows the bank to employ temporarily idle funds in interest bearing assets that usually can be converted quickly into cash. The speed of conversion, however, depends on the quality of the investment.
