What is Buying Power?
In the financial world, the phrase "buying power" has two meanings. One is the amount of inflation.a person can use to invest in securities (and that can include the investor borrows in order to buy securities). The other more common definition is the quantity of goods or services that a dollar can buy. A decrease in buying power is called
How Does Buying Power Work?
Let's assume that $1 bought 1.50 gallons of gas in 1987. Today, $1 buys about 0.50 gallons. This is an example of the change in the buying power of the American dollar.
Two general theories explain decreases in buying power. The first, the demand-pull theory says that prices increase when demand for goods and services exceeds their supply. The second, the cost-push theory, says that companies create profit margins.when they raise their prices to cover higher supply prices and maintain
The Bureau of Labor Statistics (BLS) calculates and publishes the Consumer Price Index (CPI), which measures decreases in buying power. The CPI measures the change in the retail prices of approximately 80,000 specific goods and services, called the market basket. The BLS calculates the CPI by comparing the cost of the market basket to the same basket in the starting (usually 1982-1984). To do this, the BLS sets the average price of the market basket during the years 1982, 1983 and 1984 to equal 100. Then in every subsequent period, the BLS calculates price changes in relation to that number. A CPI of 120, for example, means that prices are 20% higher than they were in the base period.
Why Does Buying Power Matter?
Changes in buying power directly or indirectly affect nearly every financial decision, from consumer choices to lending rates, and from asset allocation to prices. Buying power also offers important clues about the state of an . Most economists agree, for example, that moderate decreases in buying power are a sign of a growing economy and that increases in buying power are a sign of stagnation.

For this reason, many use
Buying power also affects securities values by way of the discount rate. When inflation is high or rising, the future dividends or interest payments from anare worth less. In broad , the higher inflation goes, the higher the discount rate goes, and the lower the value of the security goes. The reverse is also true.
Because the Federal Reserve’s job is to maintain long-term economic prosperity through the execution of monetary policy, it takes a keen interest in buying power when deciding whether to raise or lower the federal funds rate. This is one reason some analysts consider inflation a measure of the effectiveness of certain government policies.
Contracts and other obligations involving payments over time often consider buying power. For example, many labor contracts tie wage adjustments to changes in the, as do some , child , rent, royalty and other obligations affected by changes in buying power. People living off fixed are particularly affected by changes in buying power, and this is why the government usually adjusts checks and food stamps as well as the wages of federal employees and members of the military on a regular .
