National Consumer Price Index (CPI) is the key gauge for inflation in Japan. Simply put, inflation reflects a decline in the purchasing power of the Yen, where each Yen buys fewer goods and services. In terms of measuring inflation, CPI is the most obvious way to quantify changes in purchasing power. The report tracks changes in the price of a basket of goods and services that a typical Japanese household might purchase. An increase in the index indicates that it takes more Yen to purchase this same set of basic consumer items.

Markets will typically pay more attention to "CPI excluding Fresh Food," because it excludes volatile food prices that can distort overall CPI. The headline figure for CPI is the percentage change in the index on a month to month or year to year basis.

As the most important indicator of inflation, CPI figures are closely followed by the Bank of Japan. Rising Consumer Prices may prompt the BoJ to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the Yen more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Yen.

The key gauge for inflation in Canada. Simply put, inflation reflects a decline in the purchasing power of the Canadian Dollar, meaning each Dollar buys fewer goods and services. CPI is the most obvious way to measure changes in purchasing power - the report tracks changes in the price of a basket of goods and services that a typical Canadian household might purchase. An increase in the index indicates that it takes more Dollars to purchase this same set of basic consumer items.

As the most important indicator of inflation in Canada , Consumer Price figures are closely followed by Canada 's central bank. The Bank of Canada has a target inflation band of 1 - 3 % and uses CPI and Core CPI as its principle gauge (the Bank of Canada posts inflation targets and CPI on their homepage). A rising CPI may prompt the central bank to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the Dollar more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Dollar.

An inflation-adjusted measure that reflects the value of all goods and services produced in a given year, expressed in base-year prices. Often referred to as "constant-price," "inflation-corrected" GDP or "constant dollar GDP".

An aggregated measure of the sales of retail goods over a stated time period, typically based on a data sampling that is extrapolated to model an entire country. In the U.S., the retail sales report is a monthly economic indicator compiled and released by the Census Bureau and the Department of Commerce. The report covers the previous month, and is released about two weeks after the month-end. Comparisons are made against historical data; year-over-year comparisons are the most-reported metric because they account for the seasonality of consumer-based retail.
