Deciding which money market mutual fund is right for you is important, but this should give you some food for thought, and help you get started as you begin your search. Remember that the benefits of a money market fund are the liquidity they provide while maintaining interest rates which are better than you’d find in a traditional savings account or money market account. Also keep in mind that yields change daily. The Money Market enables the commercial banks to use their excess reserves in profitable investment. The main objective of the commercial banks is to earn income from its reserves as well as maintain liquidity to meet the uncertain cash demand of the depositors. In the money market, the excess reserves of the commercial banks are invested in near-money assets (e.g., short-term bills of exchange), which are easily converted into cash. Thus, commercial banks earn profits without sacrificing liquidity.
