Deflation is when the cost of goods decreases over time, and thereby "deflate" in their prices. For example, deflation would exist when something that cost $1 last year then costs only 95 cents this year. The value of paper money (e.g., a dollar bill) may increase during deflation. Annual interest rates on savings can even become negative rather than the usual positive, as depositors may have to pay banks to safeguard the money.
Deflation is the opposite of inflation, but liberals consider deflation to be worse. The Great Depression, for example, was characterized by deflation. Japan has struggled with deflationary forces since the mid-1990s.[1]
Some properly disagree with the liberal opposition to deflation. As one observer points out, "[t]he period of the greatest growth in the U.S. during the nineteenth century, from 1820 to 1850 and from 1865 to 1900, was associated with significant deflation."[2]
Forces that push an economy towards deflation include the following:
Deflation causes declines in gold prices and interest rates, but increases in the value of long-term bonds and potentially the stock market as investors seek higher rates of return than bank deposits offer. However, rates of default on bonds can increase due to deflation as borrowers have difficult paying back the principal.
Food deflation was rampant in 2016, due to increases in supply and low-cost competition.[3] Retail grocers lost in value despite increases in the stock market overall, including Wal-Mart. "Kroger, Whole Foods Market, Sprouts Farmers Market, and Supervalu lost 17%, 29%, 8%, and 31% of their respective value" in 2016.[3]
