Purchase power, what is it?
Another name for purchasing power is “buying power”. It is a way to quantify the purchasing power of a certain currency, such as the dollar.
The buying power of a dollar (or any other currency) tends to decline when prices for goods and services increase over time. Your buying power has diminished, for instance, if a tank of gas used to cost $20 but now costs $50.
Governments trace and measure purchasing power to monitor the state of their economy, as it impacts every sector. Also, in an effort to keep the economy robust, they enact policies that affect buying power.
Using the Consumer Price Index to Evaluate Spending
One indicator of inflation and buying power is the consumer price index, or CPI. In the US, the Bureau of Labor Statistics monitors changes in product prices and disseminates this information to the public through the Consumer Price Index (CPI).
The CPI is a statistical measure that follows the trend of market prices over time for a selection of products and services bought by consumers. Transportation, housing, food, and healthcare are all staples in most people’s grocery lists. As a percentage compared to the prior month, CPI is presented. As an example, the Bureau of Labor Statistics reports that the U.S. consumer price index rose 5% from March 2022 to March 2023.
Purchasing power parity
The purchasing power parity (PPP) index compares the buying power of various national currencies. It presupposes that several currencies should simultaneously have the same purchasing power. Simply said, purchasing power parity (PPP) states that, after conversion to local currency, one U.S. dollar would purchase the same quantity of goods worldwide.
The market exchange rate between the dollar and the euro would be 1:2 if, for instance, the price of a bottle of soda in France was 2 euros and in the US it was $1. That is based on the premise that the two countries’ purchasing powers are exactly equal.
Although PPP is a theoretically sound economic framework, it has little practical effect on the value of currencies. Rather, market forces of supply and demand dictate the value of one currency relative to another. In reality, PPP is more of a tool for comparing currencies according to the products and services they can buy than a factor in determining exchange rates.
After adjusting for foreign exchange rates, economists utilize the PPP theory to compare a basket of commodities in two different currencies. Simply said, the PPP is the rate at which the currency of one nation would have to swap for the currency of another nation in order to purchase the same quantity of goods and services. Thus, the buying power of Americans in other countries can be affected by the value of foreign currencies relative to the dollar.
The impact of purchasing power
A person’s ability to spend their money on products and services is directly related to their purchasing power. The state of the economy and stock prices are also impacted. Reason being, more people will find themselves in a financial bind if the value of a dollar drops sharply and basic living costs rise. The economy’s vitality will thereafter decline.
Considerable influence on buying power is exerted by the present interest rate. Purchasing power decreases as interest rates increase. In 2021, for instance, mortgage rates hit record lows. A 3% interest rate may have been negotiated for a mortgage by a homebuyer in that year.
Two years down the road, following the Federal Reserve’s aggressive rate hikes, the identical homebuyer could be eligible for a mortgage interest rate of 7%. The buying power of the homebuyer would be drastically diminished by that higher mortgage rate. Due to the higher interest rate, the individual would need to purchase a significantly less expensive property in 2023 in order to maintain the same monthly payment as in 2021.
Inflation and purchasing power
The buying power of the average person is diminished by inflation, which is defined as a general increase in the cost of living. Money won’t go as far when prices rise because of the decline in buying power.
Think about what a middle-class family’s yearly income was in 1983. It might have covered a suburban home’s mortgage, weekly groceries, and an annual trip. In order to cover the same housing, food, and vacation costs forty years hence, a family’s income would need to be nearly three times higher. As a result of inflation, the buying power of the item decreases over time.
Example of purchasing power
Prolonged adjustments in the economy have always included substantial changes in purchasing power. The Great Recession, for instance, was a worldwide economic downturn that lasted from 2007 to 2009. A steep fall in buying power was a hallmark of the Great Recession, which was also characterized by rising unemployment and persistent inflation.
According to studies, consumer spending dropped significantly as a result of lower purchasing power. Going out to restaurants was one place where folks cut back considerably. From 2006 to 2009, expenditure on food consumed away from home decreased by 11.5%, according to data from the U.S. Department of Agriculture’s Economic Research Service.
The impact of buying power on investment returns
You can’t limit the impact of a change in your buying power to changes in the prices of tangible products like food and groceries. The buying power of your investments can be diminished due to decreased purchasing power. This is because the value of your investments will be lower when you withdraw them.
If you want to protect your buying power from the possibility of inflation, you should prioritize investments with a return rate higher than inflation. Your investing goal, time horizon, and risk tolerance are all important considerations when picking an investment destination. Your investments will have more time to bounce back from a decline in purchasing power if your time horizon is greater.
