Deflation

Decrease in the general price level of goods and services

In economics, deflation is a decrease in the general price level of goods and services. Deflation occurs when the inflation rate falls below 0%. Inflation reduces the value of currency over time, but deflation increases it. This allows more goods and services to be bought than before with the same amount of currency. Deflation is distinct from disinflation, a slowdown in the inflation rate; i.e., when inflation declines to a lower rate but is still positive.
