The German CPI comes out at 0.5% from the previous 0.5%. This data came out right on forecast.
The CPI is used to gauge the changes in purchasing power of that nation's currency over time. This measures the rate of inflations experienced by the consumer. An increasing CPI means that the currency is essentially buying less as the strength of the currency is falling, which is not necessarily a bad thing. When CPI is unchanged, the currency is stable.
