Records sales of previously owned homes in the United States . This report provides a fairly accurate assessment of housing market conditions, and because of the sensitivity of the housing market to business cycle twists, it can be an important indicator of overall conditions at times when housing is particularly important to the economy.

While used home sales are not counted in GDP, they do affect the United States economy. Sellers of used homes often use capital gains from property sales on consumption that stimulate the economy. Higher levels of consumer spending may also increase inflationary pressures, even as they help grow the economy.

The existing home sales report is not as timely as other housing indicators like New Home Sales or Building Permits. By the time the Existing Home Sales are recorded, market conditions may have changed.

The headline is the total value of properties sold.

The BRC  Retail Sales Monitor is an accurate monthly measure of retail sales performance that acts as both a benchmark for participating retailers and as a key economic indicator.

The RSM measures changes in the actual value of retail sales based on figures supplied directly by participating members. Originally set up at the request of BRC members to benchmark their own business performance against the wider sector, the BRC  Retail Sales Monitor is an authoritative measure on the health of the UK retail sector and the wider economy.

A survey of both wage-earning and non-working households, such as those classified as single-member, unemployed, or retired. The headline figure is the percentage change in average spending per household from the previous year. Increases in household spending are favorable for the Japanese economy because high consumer spending generally leads to higher levels of economic growth. Higher spending is also a sign of consumer optimism, as households confident in their future outlook will spend more. At the same time accelerated growth exerts inflationary pressure, which can lead to interest rate increases in the future.

A survey of the current state of the business sector in Australia . Based on a survey of hundreds of small and large sized companies, the National Australia Bank delivers monthly comprehensive quarterly reports.

This comprehensive survey primarily provides insight into the state of the Australian economy and puts forth leading indicators that signal its future direction. Thus the survey's findings, if unexpected, have the power to move markets directly.

The National Australia Bank releases both a monthly and quarterly report. The quarterly report is more comprehensive, surveying around 1000 small to large non-farm firms. The quarterly report provides greater detail on the data as well as a short to mid-term outlook of Australia . Because of seasonal volatility and government protections the survey only excludes the farm sector.

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.

John C. Williams is President and CEO of the Federal Reserve Bank of San Francisco.

Measures the per volume change in output from mining, quarrying, manufacturing, energy and construction sectors in Italy. Industrial production is significant as a short-term indicator of the strength of Italian industrial activity. High or rising Industrial Production figures suggest increased production and economic expansion. However, uncontrolled levels of production and consumption can spark inflation.

The report is only a preliminary estimate figure that does not move the markets much. The figure is released in headlines as a monthly percent change.
