MarketplaceMoney Market Fund Interest RatesPosted on January 26, 2010. What will happen to money market rates if the Fed Funds lowers interest rates on September 18? Hello Well in the passage the market price drops some. But then he slowly gains back and is fortunately a little higher. When the Fed moves the funds rate down, all other short-term rates will go down as well, and because money market funds invest in just such securities, the rates they pay (performance ) will also fall. However, the value of your money market fund will not fall, your actions should remain "price" at $ 1 per share. Only your future performance will be lower.
