The Consumer Price Index (CPI) measures the change in the price of goods and services from the perspective of the consumer. It is a key way to measure changes in purchasing trends and inflation.

A higher than expected reading should be taken as positive/bullish for the GBP, while a lower than expected reading should be taken as negative/bearish for the GBP.

CPI assesses changes in the cost of living by measuring changes consumer pay for a set of items. CPI serves as the headline figure for inflation. Simply put, inflation reflects a decline in the purchasing power of the 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 a typical American household might purchase. An increase in the Consumer Price Index indicates that it takes more dollars to purchase the same set basket of basic consumer items.

Inflation is generally bad news for the economy, causing instability, uncertainty and hardship. To address inflation, the Fed may raise interest rates. However, the Fed relies on the PCE Deflator as its primary gauge of inflation because the CPI does not account for the ability of consumer to substitute out of CPI's set. Price changes tend to cause consumers to switch from buying one good to a less expensive-other, a tendency that the fixed-basket CPI figure does not yet account for. Given that the PCE Deflator is a more comprehensive calculation, based on changes in consumption; it is the figure the Fed prefers.

The figure is released monthly, as either a month over month annualized percentage change, or percentage change for the full year. The figure is seasonally adjusted to account seasonal consumption patterns.Inflation is generally bad news for the economy, causing instability, uncertainty and hardship.

In the United Kingdom, the Retail Prices Index or Retail Price Index (RPI) is a measure of inflation published monthly by the Office for National Statistics.

A monthly survey that measures change in input prices as incurred by UK manufacturers. Input prices include the cost of materials used plus operation costs of running the business. The index can be used as a measure of inflation, given that higher input costs will likely be passed on from producers to consumers in the form of higher retail prices.

The headline is the percentage change in the Producer Price Index (Input) from the previous quarter and previous year.

A monthly survey that measures the price changes of goods produced by UK manufacturers. The figure is also known as "Factory Gate Price" because it usually matches the price of goods when they first leave the factory. Increased prices in manufacturing typically lead to higher retail prices for consumers. However, it is also likely that higher output prices are caused by manufacturers charging a higher premium due to higher demand for their goods. Consequently, market trends in consumption should be considered with Output PPI to avoid data misinterpretation.

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 France , 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 French household might purchase. An increase in the index indicates that it takes more Euros to purchase the same set of basic consumer items.

A broad measure of the movement of single-family house prices. Apart from serving as an indicator of house price trends, the House Price Index (HPI) provides an analytical tool for estimating changes in the rates of mortgage defaults, prepayments and housing affordability. It is a weighted, repeat-sales index, which means that it measures average price changes in repeat sales or refinancings on the same properties.

The value of orders placed for relatively long-lasting goods. Durable Goods are expected to last more than three years. Such products often require large investments and usually reflect optimism on the part of the buyer that their expenditure will be worthwhile.

Because orders for goods have large sway over the actual production, this figure serves as an excellent forecast of US output to come. Durable Goods are typically sensitive to economic changes. When consumers become sceptical about economic conditions, sales of durable goods are one of the first to be impacted since consumers can delay purchases of durable items, like cars and televisions, only spending money on necessities in times of economic hardship. Conversely, when consumer confidence is restored, orders for durable goods rebound quickly.

The number of new building projects authorized for construction. The figure is widely used as an indicator for developments in the housing market, since receiving a permit to build is the first step in the construction process. Thus growth in Building Permits reflects growth in the construction sector. Also, due to the high outlays needed for construction projects, an increase in Building Permits suggests corporate and consumer optimism. Additionally, because leading indicators for the housing market respond quickly to changes in the business cycle, the Building Permit figure can act as a leading indicator for the economy as a whole.

The headline is the seasonally adjusted percentage change in Building Permits from the previous month.

Gauges the change in the number of new houses built in the United States. Housing Starts are one of the earliest indicators of the housing market, only trailing Building Permits in timeliness.

Because high outlays are needed to start construction projects, an increase in Housing Starts implies an increase in investment and business optimism. Finally, the Housing Starts figure gives insight into consumer activity, since new home purchases typically require a large investment for consumers. Given such connections to consumer and corporate sentiment, real estate generally leads economic developments. A sharp drop in new home construction is a warning signal of economic slowdown. Conversely, a rebound in the Housing Starts paves the way for economic recovery.

Housing Starts data is differentiated by building types (single family houses, 2 to 4 residence units and 5 or more residence units). The single family housing starts is a more reliable economic indicator than multi family housing starts, as single family house building is driven by demand and consumer confidence, whereas multi family house building is more often motivated by speculative real estate investors. The report headline is expressed in volume of houses built. The figures are in the thousands of units.

Measures changes in the volume of output produced by the manufacturing, mining, and utility sectors in the USA. Because industrial production is a measure of output volume rather than dollar value, the figure is not distorted by inflation and is considered a more "pure" indicator for US industry. Though industrial production only accounts for a relatively small portion of the GDP, it accounts for most of the volatility in GDP and is considered highly sensitive to changes in interest rate and consumer demand. Therefore understanding trends in this figure are important to forecasting the GDP. High or rising Industrial Production figures suggest increased production and economic expansion. However, uncontrolled levels of production and consumption can spark inflation.

The figure varies significantly month to month due to the fact that seasonal and weather related factors often alter factory production and utility demand. Because of this volatility, the report has limited market impact.

The figure is calculated as a weighted aggregate of goods and reported in headlines as a percent change from previous months.
