Money can be more effective when used for investment in physical plant and equipment or inventories or some other largely illiquid investment. But, when the supply of money rises suddenly the easiest way to make that money return anything is to put it in the securities markets (think in terms like putting it in a money market fund instead of as cash in your pocket).
