In economics, deflation is a decrease in the general price level of goods and services.[1] Deflation occurs when the inflation rate falls below 0% (a negative inflation rate). Inflation reduces the value of currency over time, but sudden 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 slow-down in the inflation rate, i.e. when inflation declines to a lower rate but is still positive.[2]

Disinflation is a decrease in the rate of inflation – a slowdown in the rate of increase of the general price level of goods and services in a nation's gross domestic product over time. It is the opposite of reflation.

If the inflation rate is not very high to start with, disinflation can lead to deflation – decreases in the general price level of goods and services. For example if the annual inflation rate one month is 5% and it is 4% the following month, prices disinflated by 1% but are still increasing at a 4% annual rate. If the current rate is 1% and it is the -2% the following month, prices disinflated by 3% and are decreasing at a 2% annual rate.
