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.

Assessment of consumer sentiment regarding business conditions, employment and personal income. Based on a representative sample of thousands of mail-in surveys, the Conference Board index has the largest pooling sample of any US measure of consumer confidence. Consumer Confidence levels are generally linked with consumer spending. For instance, when consumer confidence is on the rise consumer spending tends to increase. Low or falling consumer confidence on the other hand is typically associated with decreased spending and consumer demand.

Some analysts criticize the Consumer Confidence figure for its volatile tendencies and weak connection to household expenditure, turning instead to the University of Michigan Consumer Confidence numbers. The volatility of the Consumer Confidence figure is attributed to two factors: its pooling size and the survey time frame focus. The Conference Board surveys an entirely new group of people each month, resulting in more erratic month to month figures. Additionally, the survey queries respondents on expectations for the following six months, a relatively short term evaluation. Conversely, the University of Michigan survey will re-poll many individuals and focuses on expectations for the next one to five years. The long term focus has a stabilizing effect on consumer confidence.

Survey results are printed in the headlines where 100 reflects a recent base year.

The headline inflation gauge for Australia. Simply put, inflation reflects a decline in the purchasing power of the Aussie Dollar, where each Dollar 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 is typically bought by a metropolitan Australian households. An increase in the index indicates that it takes more Australian Dollars to purchase this same set of basic consumer items.

Unlike most other countries, Australia publishes CPI quarterly instead of monthly, increasing the market impact of the report upon release. The headline number is released as the percentage change from the previous quarter or year.
