Assesses changes in the cost of living by measuring changes in the prices of consumer items. The CPI is the headline inflation figure that indicates the strength of domestic inflationary pressures. Simply put, inflation reflects a decline in the purchasing power of the Euro in Germany , where each Euro buys fewer goods and services. CPI is the most popular way to measure changes in purchasing power. The report tracks changes in the price of a basket of goods and services that a typical German household might purchase. An increase in the index indicates that it takes more Euros to purchase this same set of basic consumer items.

The German CPI is significant as one of the primary gauges of inflation. As the largest Eurozone economy, inflation in Germany will contribute significantly to inflation in the Eurozone and the behavior of the European Central Bank. High or rising inflation acts as a signal to the ECB to raise interest rates, an action which will result in the strengthening of the Euro. The headline figure for CPI is the percentage change in monthly and annualized percentage term.

The Harmonized Index of Consumer Prices (HICP) reflects changes in the prices of consumer goods and services in a specified period of time. The HICP measures changes of the average price level for goods and services that households consume (the fixed consumer basket). HICP is pure price index. It does not reflect the changes in buying or consumption patterns, brands, and does not reflect the effect of outlet and service provider substitution.

Tracks inflation in producer and import prices in Switzerland . The headline figure is the percentage change in the index from the previous period.

Changes in this index will generally precede changes in the consumer price index, as higher import costs and producer prices tend to eventually be passed to consumers. As with any indicator of inflation, increases in producer and import prices tend to act as an appreciating weight for the Swiss franc because inflationary pressures are almost always met with interest rate increases from the Swiss central bank.

The figure represents changes in the combined producer and import price index, calculated from changes in producer prices and import prices, giving appropriate weight to the proportion of domestic and imported goods.
