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.

On A Technical Note: The CPI includes over 200 categories of goods and services included, divided into 8 main groups, each with a different weight: Housing, Transportation, Food, Medical Care, Education and Communication, Recreation, Apparel, and Other Goods and Services.

CPI Excluding Food and Energy - United States

The CPI is also reported excluding food and energy; two of its most volatile components. These components are particularly sensitive to temporary economic factors like oil prices, natural disasters and seasonal affects. Consequently, CPI excluding Food and Energy provides a more stable figure, but at the cost of overlooking two significant sectors in the economy (together food and energy comprise nearly a quarter of the goods included in the CPI).

The figure is the monthly percent change in the index.

The Gross Domestic Product is a comprehensive measure of an overall production and consumption of goods and services. GDP serves as one of the primary measures of overall economic well-being. While GDP announcements generally conform to expectations, unanticipated changes in this metric can move markets.

Robust GDP growth signals a heightened level of economic activity and often a higher demand for the domestic currency. At the same time, economic expansion raises concerns about inflationary pressures which may lead monetary authorities to increase interest rates. Thus better than expected GDP figures are generally bullish for the Euro, while negative readings are generally bearish.

Technically, Gross Domestic Product is calculated in the following way:

GDP = C + I + G + (EX - IM)

where

C = private consumption, I = private investment, G = government expenditure, EX = exports of goods and services, IM = imports of goods and services.

French GDP figures, officially called Quarterly National Accounts, are released quarterly. The headline figures are annualized percentage changes in real and nominal GDP.

The GDP for the United States is a gauge of the overall output (goods & services) of the US economy on the continental US GDP is the most comprehensive overall measure of economic output and provides key insight into the driving forces of the economy.

GDP Influence On Markets
If the figure increases, then the economy is improving, and thus the dollar tends to strengthen. If the number falls short of expectations or meets the consensus, dollar bearishness may be triggered. This sort of reaction is again tied to interest rates, as traders expect an accelerating economy, consumers will be affected by inflation and consequently interest rates will rise. However, much like the CPI, a negative change in GDP is more difficult to trade; just because the pace of growth has slowed does not mean it has deteriorated. On the other hand, a better than expected number will usually result in the dollar rising as it implicates that a quickly expanding economy will sooner or later require higher interest rates to keep inflation in check. Overall though, the GDP has fallen in significance and its ability to move markets since most of the components of the report are known in advance

Due to the untimeliness of this report and because data on GDP components are available beforehand, the actual GDP figure is usually well anticipated. But given its overall significance GDP has the tendency to move the market upon release, acting to confirm or upset economic expectations. Robust GDP growth signals a heightened level of activity that is generally associated with a healthy economy. However economic expansion also raises concerns about inflationary pressures which may lead to monetary policy tightening.

Gross Domestic Product is calculated in the following way
GDP = C + I + G + (EX - IM)
where
C = private consumption
I = private investment
G = government expenditure
EX = exports of goods and services
IM = imports of goods and services

The figure is commonly reported in headlines as an annualized percentage, based on quarterly data.

On a technical note: The GDP can be reported in either real or nominal terms, real GDP being adjusted for inflation. GDP actually has three releases, as an Advanced, Preliminary, and Final figure. The Advanced figure is released four weeks following the quarter's end. One month later, the Preliminary GDP is released, followed by the Final GDP measure at the end of the quarter following the reporting quarter. As the most timely measure, the Advanced GDP tends to move markets the most.

Comprehensive measure of how much consumers spend each month, counting expenditures on durable goods, consumer products, and services. Personal Consumption is a comprehensive measure of GDP; consequently the figure is watched as an indicator for economic trends. Spending also has direct affect on inflationary pressures.

A healthy Personal Spending figure means that consumers are buying goods and services, fueling the economy and spurring output growth. The report is particularly valued for forecasting inflationary pressures. Taken in excess these high levels of consumption and production may lead to an overall increase in prices. Indeed, the Fed uses a measure of inflation derived from the PCE as their primary gauge of inflation.

On the other hand, persistently low Personal Spending may result in decreasing levels of output and an economic downturn.

Because income is either spent or saved, Personal Spending (when reported as a percent of income rather than the headline percent change) has an inverse relationship to personal saving. Economists watch the growth of Personal Spending in relation to income and saving to determine if consumers are living beyond their means, which would influence levels of borrowing and future consumption.

The PCE figure is released in headlines as a percent change from the previous month.

Core Personal Consumption Expenditure
Volatile items like food and energy can fluctuate widely due to seasonal and non-systemic factors. In order to provide a less erratic picture of Personal Consumption, food and energy items are excluded in the PCE core report.

The headline figure of PCE is expressed in percentage change in spending for the quarter.

Note: The Personal Consumption Expenditure figure is reported with the Personal Income and Outlays figure.
