The ANZ job advertisement series measures the number of jobs advertised in the major daily newspapers and Internet sites covering the capital cities each month.

The number of domestic building permits granted for the month. Strong growth in new approvals and permits indicates a growing housing market. Because real estate generally leads economic developments - housing tends to thrive at the start of booms and wane at the onset of recession. The figure can be used with others to forecast future growth in the economy as a whole. For this reason Business Approvals is one of eight components used to construct the Conference Board Leading Index, a widely used index to forecast Australia's economic course. A strong housing market also tends to lead consumer spending. The headline number is the seasonally adjusted percentage change in new building approvals from the previous month.

A monthly gauge of manufacturing activity and future outlook. It is comparable to the US ISM survey, similarly based on the opinions of executives in manufacturing companies. Purchasing managers are tasked with gauging future demand and adjusting orders for materials accordingly. The PMI summarizes the opinions of these executives to give a picture of the future of the manufacturing sector. A higher PMI indicates that materials purchases are increasing and that the economic outlook is positive. Alternately, a lower PMI means orders for materials are down and the future outlook is less favorable. By nature, the figure is very sensitive to the business cycle and tends to match growth or decline in the economy as a whole.

The PMI is presented as an index with a value between 1-100.

Gauge for overall performance of the German manufacturing sector. Through asking executives about sales and employment outlook, the survey strives to provide useful information about the business climate that can lead to developments in employment, output and consumption. The PMI survey results are the result of interviews with business executives. Manufacturing is an important sector in Germany , which is why changes in Manufacturing PMI can provide a good indicator to the overall economic condition in Germany as well as Euro-zone. However, despite the timeliness of the report, Manufacturing PMI is not a big market mover.
The survey results are quantified into index where 0 represents long term manufacturing business conditions. The headline figure is expressed in percentage change.

The Euro-zone Manufacturing Purchasing Managers Index (PMI) assesses business conditions in the manufacturing sector. Because the manufacturing sector represents nearly a quarter of total Euro-zone GDP, the Euro-zone Manufacturing PMI is both a significant and timely indicator of business conditions and the general health of the economy. Results are quantified in an index in which values above 50 indicate an expected increase of business conditions and values below 50 signal an expected deterioration.

Level of a diffusion index based on surveyed investors and analysts. Above 0.0 indicates optimism, below indicates pessimism. This is a survey of about 2,800 investors and analysts which asks respondents to rate the relative 6-month economic outlook for the Eurozone.
 

Dollar volume of new orders, shipments, unfilled orders and inventories as reported by domestic manufacturers. Factory Orders is not a widely watched economic release. The Advance Release on Durable Goods Activity reported one week earlier tends grab more market attention, given that durable goods make up more than half of factory orders.

Factory Orders does provide a comprehensive look at the manufacturing sector. Specifically, the New Orders figure can act as a gauge of demand across industries while Shipments are indicative of supply. The Unfilled Orders and Inventory figures reconcile the balance between New Orders and Shipments; high Shipments are indicative of an excess of demand relative to supply, high Inventories signal an excess of supply over demand.

Figures are reported in billions of dollars and also in percent change from the previous month.

On a Technical Note: The New Orders figure measures the value of orders received by manufacturers for new products from both domestic and foreign sources. The total value of products shipped is calculated in Shipments while Unfilled Orders measures the value of goods backlogged for order but not yet shipped. Lastly, Inventories gauges the amount of unsold goods held by manufacturers.

The Australia and New Zealand Banking Group Limited (ANZ)Commodity Prices Indicator, also called the Commoditiy Price Index, measures the change in the price of exported commodities. Since Australia and New Zealand depend heavily upon commodity exports, this figure acts as a primary gauge of the two nations' GDP and economic strength.

It is the key gauge for inflation in Switzerland. Simply put, inflation reflects a decline in the purchasing power of the Franc, where each Franc buys fewer goods and services. The CPI calculates the change in the price of a predetermined basket of consumer goods and services. This basket represents the goods and services that an average household will purchase. The figure is compared to those of the previous month as well as the previous year in order to gauge changes to the costs of living on a month to month and year to year basis. The headline number is the percentage change either from the previous month's value or the previous year's value.

As the key indicator of inflation, a rising CPI may prompt the Swiss National Bank to raise interest rates in attempt to manage inflation and slow economic growth. Higher interest rates make holding the Franc more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Franc.

The indicator shows the number of unemployed people in Spain.

A country's trade balance reflects the difference between exports and imports of goods and services. The trade balance is one of the biggest components of the Balance of Payment, giving valuable insight into pressures on country's currency.

Surpluses and Deficits
A positive Trade Balance (surplus) indicates that exports are greater than imports. When imports exceed exports, the country experiences a trade deficit. Because foreign goods are usually purchased using foreign currency, trade deficits usually reflect currency leaking out of the country. Such currency outflows may lead to a natural depreciation unless countered by comparable capital inflows (inflows in the form of investments, FDI - where foreigners investing in local equity, bond or real estates markets). At a bare minimum, deficits fundamentally weigh down the value of the currency.

Ramifications of Trade Balance on Markets
There are a number of factors that work to diminish the market impact of Trade Balance upon immediate release. The report is not very timely, coming some time after the reporting period. Developments in many of the figure's components are also typically anticipated well beforehand. Lastly, since the report reflects data for a specific reporting month or quarter, any significant changes in the Trade Balance should plausibly have already been felt during that period - and not during the release of data.

However, because of the overall significance of Trade Balance data in forecasting trends in the Forex Market, the release has historically been one of the most important reports out of the any country.

Records sales of newly constructed residences in the United States. The figure is a timely gauge of housing market conditions counting home sales when initial housing contracts are signed. Because New Home Sales usually trigger a sequence of consumption, they have significant market impact upon release. In addition to the high expenditure of the new home, buyers are likely to spend more money on furnishing customizing and financing their home. Consequently, growth in the housing market spurs more consumption, generating demand for goods, services and the employees who provide them.

Generally, the housing market is tracked by a number of reports that mark different stages of the construction and home sale process. The first stage is Building Permits, which precede Housing Starts, which lead to Construction Spending, MBA Mortgage Applications and, finally, New Home Sales and Existing Home Sales. As the headline housing figure, New Home Sales are believed to control some of the volatility of other data. For instance, Building Permits and Housing Starts are considered more indicative of business confidence and production rather than consumer spending. And while Existing Home Sales figures are more indicative of consumer expenditures, they are lagging indicators with less predictive value. New Home Sales numbers are considered confirmatory of housing trends and still predictive of consumer spending.

New Home Sales is also a good indicator of economic turning points due to its sensitivity to consumer income. Buying a house is always a major expenditure, typically only undertaken when consumers have sufficient savings or are optimistic about future earnings. Historically, when economic conditions slow, New Home Sales are one of the first indicators to reflect the change. By the same token, New Home Sales undergo substantial growth when the economy has emerged from recession and wages have begun to pick up.

The report headline is the total amount of properties sold.

The Reserve Bank published its first Financial Stability Report (FSR) in October 2004. The Financial Stability Report is published six-monthly. In the Financial Stability Report we assess and report on the soundness and efficiency of the New Zealand financial system.

Evaluates the monthly change in output produced by Japan's service sector. Because this report excludes manufacturing and only measures service industries catering mainly to domestic needs, the Tertiary Industry Index is a key indicator of domestic activity. The index incorporates data from firms involved in wholesale and retail trade, financial services, health care, real estate, leisure and utilities. The report excludes industrial manufacturing sectors that tend to be influenced by foreign demand. The tertiary industry index is posted monthly as a percentage change from the previous month's figure.

An index level of 50 denotes no change since the previous month, while a level above 50 signals an increase or improvement, and below 50 indicates a decrease or deterioration.

Measures the level of production of French industries. French Industrial Production tracks relative changes in the production of goods, excluding energy and food, whether they are sold domestically or abroad. The headline figure is the percentage change in the index from the previous quarter or year.

Industrial Production is highly sensitive to the business cycle, and so can forecast changes in employment, earnings, and personal income. Consequently, Industrial Production is considered a reliable leading indicator of the overall health of the French economy.

Gauge for the overall performance of the country's service sector. The Services PMI interviews executives on the status of sales, employment, and their outlook. Because the performance of the country's service sector is extremely consistent over time, services does not impact final GDP figures as much as the more volatile figure on the manufacturing sector. For this reason Services PMI usually causes little market movement. The survey results are quantified and presented as an index on a 1-100 scale. The headline figure is the percentage change in the index.

The Eurozone Composite Purchasing Managers Index (PMI) assesses business conditions in manufacturing, construction and service sectors. The Eurozone PMI is both a significant and timely indicator of business conditions and the general health of the economy. Close correlation with the business cycle, assessed on the basis of long-term statistical data, allows to use the PMI indicator for prognosis of future GDP volumes. The PMI indices are based on  selected panels of executives in companies who report each month on real events. The subindex of intangibles sector - PMI services - is of more importance because in industrialized countries around 70% of GDP is generated in non-manufacturing sector.

Gauge for goods sold at retail outlets in the past month. Retail Sales is a leading indicator for the economy. Rising consumer spending fuels economic growth, confirms signals from consumer confidence, and may spark inflationary pressures.

The headline figure is expressed as the percentage change from the same month last year.

A monthly gauge of the UK service sector that takes into account business outlook. The survey queries executives in transport and communications, financial intermediation, business services, personal services, computing and IT, hotels and restaurants.

Purchasing managers are tasked with gauging future demand, and adjusting orders for materials accordingly. The PMI summarizes the opinions of these executives to give a picture of the future of the service sector. A higher PMI indicates that materials purchases are increasing and that the economic outlook is positive. Alternately, a lower PMI means orders for materials are down and the future outlook is less favorable. By nature, the figure is very sensitive to the business cycle and tends to match growth or decline in the economy as a whole.

Because the contribution services makes to the economy tends to be very consistent and predictable, Services PMI figures typically do not move markets

The PMI is presented as an index with a value between 1-100.

Measures changes in the selling prices producers charge for goods and services, and well as tracks how prices feed through the production process. Because producers tend to pass on higher costs to consumers as higher retail prices, the PPI is valuable as an early indicator of inflation. Simply put, inflation reflects a decline in the purchasing power of the Dollar, where each dollar buys fewer goods and services. The report also gives insight into how higher prices from raw materials flow toward the final product.

A rise in PPI signals an increase in inflationary pressures. Given the economic instability associated with rising price levels, the Fed often will raise interest rates to check inflation. A low or falling PPI is indicative of declining prices, and may suggest an economic slowdown.

The headline figure is expressed in percentage change of producer price.

Notes: The PPI records prices at various stages of production: raw goods, intermediate goods and finished goods. Though intermediate and crude goods prices do provide insight for future inflationary pressure, it is the price of finished goods that generates most interest for market participants. The finished goods data is able to gauge price pressure before the goods reach the retail market.

The Ivey Purchasing Managers Index (PMI) is an economic index which measures the month to month variation in economic activity as indicated by a panel of purchasing managers from across Canada, and is prepared by the Richard Ivey School of Business. The PMI is provided in two formats: unadjusted and seasonally adjusted. It shows responses to one question: ""Were your purchases last month in dollars higher, the same, or lower than the previous month?"" A figure above 50 shows an increase while below 50 shows a decrease. The Ivey Purchasing Managers Index is often referred to as the Purchasing Managers Index, or PMI and is sponsored by the Richard Ivey School of Business and the Purchasing Management Association of Canada (PMAC). The PMI includes both the public and private sectors and is based on month end data Ivey PMI panel members indicate whether their organizations activity is higher than, the same as, or lower than the previous month across the following five categories: purchases, employment, inventories, supplier deliveries and prices.

The actual inventories of crude oil, gasoline, and distillate, such as jet fuel, as reported on a weekly basis. The numbers are watched closely by the energy markets, and if the results differ greatly from the expected inventory levels, the market can react strongly. The inventory data can be skewed by holidays and seasonal factors. Weekly data can be unreliable and should be viewed as a part of longer-term trends, so a four-week moving average may be more useful.

The monetary base is the volume of money in the economy. It consists of the currency (banknotes and coins) in circulation and the commercial banks reserves in the Central Bank.

Dollar volume of new orders, shipments, unfilled orders and inventories as reported by domestic manufacturers. Factory Orders is not a widely watched economic release.

Factor Orders does provide a comprehensive look at the manufacturing sector. Specifically, the New Orders figure can act as a gauge of demand across industries while Shipments are indicative of supply. The Unfilled Orders and Inventory figures reconcile the balance between New Orders and Shipments; high Shipments are indicative of an excess of demand relative to supply, high Inventories signal an excess of supply over demand.

Figures are reported in billions of dollars and also in percent change from the previous month.

On a Technical Note: The New Orders figure measures the value of orders received by manufacturers for new products from both domestic and foreign sources. The total value of products shipped is calculated in Shipments while Unfilled Orders measures the value of goods backlogged for order but not yet shipped. Lastly, Inventories gauges the amount of unsold goods held by manufacturers.

A country's trade balance reflects the difference between exports and imports of goods and services. The trade balance is one of the biggest components of the Balance of Payment, giving valuable insight into pressures on country's currency.

This is the amount of foreign currency reserves that are held by the Central Bank of a country. In general use, foreign currency reserves also include gold and IMF reserves. Also, people may take into account liquid assets that can easily be converted into foreign currency.

The percentage of individuals in the labor force who are without a job but actively seeking one. A higher Unemployment Rate is generally a drain on the economy. Not only does it mean that resources are not being fully utilized, but it also results in lower consumer spending as there are fewer workers receiving paychecks.

Note: The unemployment rate generally moves slowly, so changes of only a few tenths of a percent are still considered significant. Also note that the unemployment rate does not account for discouraged workers. Therefore, in an economically depressed environment, such as that which occurred in Cold War era East Germany, the Unemployment Rate may not accurately reflect the extent of problems.

High unemployment translates into lower average wages and reduced consumer spending. As consumer spending is the majority of total expenditure, rising unemployment often leads to slow economic growth. In addition, high or rising unemployment puts downward pressure on interest rates and leads to a depreciating Franc.

The Construction Purchasing Manager's Index (PMI) measures the level of activity among purchasing managers in the construction sector of the economy. Above 50 signals industry expansion; below 50 indicates a contraction. Construction figures are an important indicator of housing demand.

Gauge for goods sold at retail outlets in the past month. Retail Sales is a leading indicator for the economy. Rising consumer spending fuels economic growth, confirms signals from consumer confidence, and may spark inflationary pressures.

The headline figure is expressed as the percentage change from the same month last year.

The indicator shows the number of unemployed people in the USA.

Continuing claims refers to unemployed workers that qualify for benefits under unemployment insurance. In order to be included in continuing claims, the person must have been covered by unemployment insurance and be currently receiving benefits. Data on unemployment claims is published by the Department of Labor on a weekly basis, allowing for frequent updates on the levels of unemployment.

Measures the output produced for each hour of labor worked. Non-farm Productivity is considered the most accurate gauge of overall business health, given farming data's small and volatile contribution to GDP. To businesses, higher productivity indicates efficient use of employees and capital. Given that labor costs make up more than two-thirds of the average businesses expenses, high productivity can allow a firm to fulfill consumer demand with less labor costs, boosting profitability. Thus trends in this report can precede investment spending and business growth. Also if prices for raw materials increase, improved productivity can save a firm from passing higher costs to the end consumer. Given such business effects, healthy productivity growth bodes well for the economy as a whole, signalling increased production capability and business growth.

Productivity is reported as output per hour per worker, categorized into industry figures.

On a Technical Note: The Non-Farm Productivity number is generated by comparing the number of hours worked (Employment Situation report) to Gross Domestic Product data.

The indicator reflects the quarterly changes in salaries and other income received by working population.

Construction Spending gauges the level of construction activity in the United States . The Construction Spending report looks at both residential and non-residential construction. The construction industry makes a significant contribution to the United States GDP in the form of investment expenditure as well as stimulus of industries related to building. Furthermore, since builders are unlikely to pour money into construction projects unless they feel the economy favors their investment, changes in business sentiment like this are usually quickly seen in construction figures. However, the report has little significance for market participants because of its untimely release. By the time the report is announced, other reports, such as Building Permits and Building Starts have already provided similar information.

The report headline is the percentage change from the previous month.

Technical notes: The construction industry is a major force to the United States economy, even without including non-construction businesses that are tied to building, such as finance, the furnishing industry, appliance industry and other manufacturing. Private Construction activity can be an effective indicator of business confidence.

Weekly report about natural gas storage change in the USA.

Measures the outstanding debt held by consumers. Consumer Credit levels coincide with the economy, rising during economic expansion and dropping during a recession. Growth in Consumer Credit means that consumers have higher spending ability, which can fuel economic growth. However, too much Consumer Debt can result in an economic slowdown in the long term if consumers become overburdened with debt, then either reducing consumption or passing debt on to the financers after bankruptcy. The headline value is the outstanding debt held by consumers.

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

The average amount of pre-tax earnings per regular employee, including overtime pay and bonuses.

Measures the per volume change in output from mining, quarrying, manufacturing, energy and construction sectors in Germany. Industrial production is significant as a short-term indicator of the strength of German industrial activity. High or rising Industrial Production figures suggest increased production and economic expansion, healthy for the Euro. 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.

The difference between the value of exports and imports in Germany. Trade Balance is one of the biggest components of Germany 's Balance of Payment. As Germany is Europe's largest economy and given Germany's export oriented economy, trade data can give critical insight into pressures on the value of the Euro.

In order to gauge the effect of German Trade Balance on the Euro, German trade is separated into intra-Eurozone trades and extra-Eurozone trades. Intra-trades between Germany and Eurozone countries have no affect on the overall valuation of Euro. Extra-trades between Germany and other countries outside of Eurozone do impact the overall Eurozone trade balance. Given Germany's large share of Eurozone exports, the figure tends to move the market upon release.

Trade surpluses reflect funds coming into Germany in exchange for goods and services. Such currency inflows may lead to a natural appreciation of a Euro, unless countered by similar capital outflows. At a bare minimum, surpluses will boost up the value of the currency.

The headline figure for trade balance is expressed in billions of Euros.

SECO Consumer Climate compiles a survey of consumer attitudes on present economic conditions and expectations of future conditions. In the months of January, April, July and October, about 1100 households are surveyed on behalf of SECO regarding their subjective evaluation of the economic situation, budget situation, inflation, job security etc.

The pattern in consumer attitudes and spending is often a major influence on stock and bond markets. For stocks, strong economic growth translates to healthy corporate profits and higher stock prices. For bonds, the focus is whether economic growth goes overboard and leads to inflation. Ideally, the economy walks that fine line between strong growth and excessive (inflationary) growth. Consumer spending accounts for a major portion of the Swiss economy, so investors want to know what consumers are up to and how they might behave in the near future. The more confident consumers are about the economy and their own personal finances, the more likely they are to spend.

An indicator of how the average level of pay is changing. The Average Hourly Earnings figure provides insight into future spending and inflation. A High Average Hourly Earnings bodes well for future consumption, as workers have more disposable income. High figures may indicate inflationary pressures due to employee's additional potential to spend. The figure is either measured in hourly or weekly averages or as a percent change from the previous month.

Private Nonfarm Payrolls measures the change in the number of total payrolls in any business, excluding general government employees, private household employees, employees of nonprofit organizations that provide assistance to individuals and farm employees.

A measure of the active portion of an economy's labor force. The participation rate refers to the number of people who are either employed or are actively looking for work. The number of people who are no longer actively searching for work would not be included in the participation rate. During an economic recession, many workers often get discouraged and stop looking for employment, as a result, the participation rate decreases. The participation rate is an important metric to note when looking at unemployment data because unemployment figures reflect the number of people who are looking for jobs but are unable to secure employment.

modern award usually defines a part-time employee as an employee who is engaged to work less than an average of 38 ordinary hours per week and whose hours of work are reasonably predictable, with a guaranteed minimum number of hours of work. Work is usually performed on regular days of the week. A part-time employee will usually be entitled to the same employment conditions as a full-time employee, but on a pro rata basis compared to the full-time hours (usually 38 per week) prescribed under the applicable industrial instrument.

The stock of unsold goods held by wholesalers. Wholesalers act as intermediaries between manufacturers or importers, and retailers. Wholesalers sell directly to retailers, who strive to act in accordance (ideally) with consumer demand. Consequently, high Wholesale Inventories indicate that unsold goods are piling up, suggesting that retailers are facing lagging consumer demand and unwilling to purchase goods. Conversely, declining Wholesale Inventories suggest retailers are buying more goods to meet strong or rising demand. Because Wholesale Inventories reflect the demand retailers have for their manufacturers' wares, the report offers an early indication of the potential strength of consumer spending.

Wholesale Inventories are reported in headlines as a percent change from the previous month.
