So deflation exerts a depressing effect on spending by raising debt burdens â which, as Fisher also points out, can lead to another kind of vicious circle, in which depressed spending because of rising real debt leads to further deflation.
Deflation can be caused by a decrease in the demand for products, an increase in the supply of products, excess production capacity, increase in the demand for money, or a decrease in the supply of money or availability of credit.uring the late 1970s and early 1980s, inflation skyrocketed as high as 14.8% in the U.S. and interest rates climbed to similar levels. Few living Americans know what it's like to face the opposite phenomenon-deflation.
