Personal Consumption Expenditure Price Index, referred to as PCE Price Index or PCEPI in English, is a financial index released monthly by the U.S. Bureau of Economic Analysis (BEA) to track the amount of personal consumption expenditures. The PCEPI has slightly different names in different U.S. agencies. For example, the U.S. Bureau of Economic Analysis calls it the Implicit Price Deflator for Personal Consumption Expenditures (IPD for PCE), while the Federal Reserve's FOMC calls it the Chain-Type Price Index for Personal Consumption Expenditures (CTPIPCE). The Federal Reserve measures consumer spending trends and the level of inflation in the U.S. economic environment by tracking the Personal Consumption Expenditure Index, which it uses as a reference to adjust monetary policy. The Fed attaches even more importance to the personal consumption expenditures index than another financial index, the consumer price index (CPI). The calculation of the personal consumption expenditure index considers the data spent by consumers to purchase goods and services, and compares the current period's results with the previous period's results, and analyzes its change rate through chain weighted calculations. This way, consumers' consumption habits, consumption decisions and other factors are taken into consideration to obtain a financial index that is more in line with market changes. The objects of personal consumption expenditure index statistics include goods and services, among which goods include durable goods and non-durable goods. When all categories of goods are included, it is called the overall personal consumption expenditures index. After removing food and energy, two commodity categories with large price and trading volume fluctuations, the core personal consumption expenditures index Core PCE Price Index is obtained. People can check the Personal Consumption Expenditure Index report released by BEA on its portal to learn about changes in U.S. consumption levels, and investors can adjust their investment strategies based on the PCE value. As a financial index closely related to people's livelihood, the personal consumption expenditure index intuitively reflects the changes in consumer spending power in the U.S. economic environment. At the same time, since consumer spending accounts for the vast majority of the U.S. economy, tracking the personal consumption expenditure index can also inform the development of the U.S. economy. The Personal Consumption Expenditure Index considers the goods and services purchased by all households across the country and has a wider range than the CPI, so it can more completely show changes in the spending power of U.S. citizens. At the same time, for the core personal consumption expenditure index, because food and energy data are excluded, the fluctuation of the personal consumption expenditure index is greatly reduced, and the impact of some special events on the index can be avoided, thus avoiding biased analysis results. The Federal Open Market Committee (Board of Governors) of the Federal Reserve stated in its "Monetary Policy Report" ("Humphrey-Hawkins Report" in English) submitted to Congress on February 17, 2000 that the Federal Reserve will use the PCE index instead of the CPI index as the main indicator to measure inflation [source]. After tracking U.S. inflation trends based on the Personal Consumption Expenditure Index, the Federal Reserve will adjust monetary policy and interest rates based on the analysis results, which will directly affect the financial strategies of consumers, producers, and investors. For example, when the PCE value rises steadily, it means that the overall U.S. economy is in a healthy development stage. However, if it rises too fast, it may mean excessive inflation. At this time, the Federal Reserve will control the market heat through monetary tightening policies such as raising interest rates and return to a relatively stable development state.
If the PCE value declines, especially if it continues to decline, it means that consumers' spending power is declining, and both purchase volume and purchase amount are declining. This is a signal that economic development is slowing down or even stagnating. The Federal Reserve may take interest rate cuts and other methods to stimulate consumption and improve the economic level. Therefore, the most important significance of the personal consumption expenditure index at present is to provide a financial index with reference value for the Federal Reserve to formulate monetary policy. How is the Personal Consumption Expenditure Index calculated? The statistical content of the PCE index includes all purchased goods (Goods) and services (Services). Among them, commodity purchases will be divided into durable goods (Durable Goods) and non-durable goods (Non-Durable Goods). Durable goods refer to goods with a service life of more than three years, such as cars, appliances, furniture and electronic products. Non-durable goods refer to goods with a service life of less than three years, such as gasoline, clothing, groceries, cosmetics, health care products and health-related products. The "services" in the PCE index refer to all services provided by companies to individual consumers, such as bank account maintenance services, financial services, entertainment services, and even backyard gardening services. When the U.S. Bureau of Economic Analysis (BEA) produces the Personal Consumption Expenditure Index, it collects extensive data, mainly from surveys of businesses by various agencies, including: statistical reports issued by the U.S. Census Bureau and other government agencies; reports issued by administrative and regulatory agencies; Reports from private organizations such as various industry associations; After collecting the data, BEA will calculate it based on the Fisher-Ideal index model to obtain the personal consumption expenditure index value for the current period. For the PCE index change rate, the personal consumption expenditure index uses the chain index analysis method, that is, comparing the personal consumption expenditure index values in two consecutive periods to measure its change rate. Through chain index analysis, consumers' consumption habits and consumption strategies can be taken into consideration. For example, when the price of a commodity rises, consumers will choose another cheaper commodity to replace it. This change in consumption habits will be considered in the chain index calculation by comparing consecutive periodic values. What types of personal consumption expenditure index are there? There are two main types of personal consumption expenditure index: Overall Personal Consumption Expenditure Index (Chain-Type Price Index) Core PCE Index. The overall personal consumption expenditure index refers to an index that calculates personal consumption expenditures including all goods and services, especially food and energy commodities. The core personal consumption expenditures index refers to the personal consumption expenditures index excluding food and energy commodities. The reason why the core personal consumption expenditure index is produced is that food and energy commodities will experience large price fluctuations due to financial investment, and some financial investments will affect the transaction volume of food and energy commodities. However, these transaction volumes and transaction amounts are not fluctuations caused by actual consumers' daily consumption. Therefore, the index fluctuations caused by them cannot accurately reflect the development trend of the economy, nor can the overall PCE accurately measure inflation. Therefore, institutions such as the Federal Reserve measure inflation more by tracking the core personal consumption expenditures index. How to check the Personal Consumption Expenditure Index? Users can query the overall personal consumption index and core personal consumption index data on the personal consumption index portal of the Federal Reserve Economic Data website: Step 1: Go to the Federal Reserve Economic Data Website Step 2: Enter: Chain-Type PCE Price Index in the search box to enter the personal consumption data information page: Among them, the first is the overall personal consumption index, and the second is the core personal consumption index. The following is the overall personal consumption index trend chart as of December 25, 2024: Data source The following is a chart of the core personal consumption index as of December 26, 2024:
As can be seen from the overall personal consumption index trend chart and the core personal consumption index trend chart, the index showed a clear upward trend in the 1970s and 1980s, as well as at the beginning of this century and during the COVID-19 period in 2020. This shows that in several economic crises, the consumption index increased significantly, and it was an overall increase, because after removing food and energy, the growth showed the same situation. What is the difference between PCE and CPI? The CPI index and the PCE index are the most important financial indicators for measuring consumption levels. The Federal Reserve will track these indicators to understand the market's consumption capacity, and understand the rate of change of inflation based on changes in the index. Then, based on the analysis results, it will adjust monetary policy, interest rates and other financial policies. However, there are obvious differences between CPI and PCE, including: Data source: CPI uses consumer spending based on household surveys, while PCE uses consumer spending based on business surveys. Data adoption categories: CPI and PCE have several obvious differences in data adoption categories. First of all, CPI will take housing equivalent rent into consideration, but PCE will not. Secondly, for medical expenses, the CPI only considers the medical costs paid by the family out of pocket, while the PCE will include the medical care costs purchased by a third party on behalf of the family, such as medical insurance purchased by the employer for its employees. Calculation method: CPI uses a statistical calculation method based on the Laspeyres index, which will not take into account factors such as consumer consumption habits and changes in strategies; PCE uses a statistical calculation method based on the Fisher-Ideal index, which will take into account factors such as consumer consumption habits and changes in consumption strategies. Publisher: The CPI is produced and released monthly by the U.S. Bureau of Labor Statistics (BLS), and the PCE is produced and released monthly by the U.S. Bureau of Economic Analysis (BEA). Index reporting format: CPI will publish classified statistical data according to different categories, so that analysts can obtain more detailed analysis results, while PCE will not provide classified data statistical results.
