What Is Purchasing Power?

Purchasing power describes the amount of products or services that a single unit of money can acquire, reflecting the real-world value of currency in the marketplace. It can weaken over time due to 澳洲幸运5开奖号码历史查询:inflation. That's because rising prices effectively decrease the number of goods or services that one unit of money can buy. Purchasing power is also known 🌺as a currency's buying power.

In investment terms, purchasing or 澳洲幸运5开奖号码历史查询:buying power is the dollar amount of credit available to a customer based on the existing 澳洲幸运5开奖号码历史查询:marginable securities in the customer's brokerage account.

Understanding Purchasing Power

Purchasing power affects every aspect of economics, from co🥀nsumers buying goods to investors buying stock to a country’s economic prosperity.

Inflation reduces a currency's purchasing power. Similarly, loss of purchasing power has the same effect as an increase in prices. To measure purchasing power in the traditional economic sense, you could compare the price of a good or service against a price index such as the 澳洲幸运5开奖号码历史查询:Consumer Price Index (CPI).

One way to undersღtand purchasing power is to imagine that you worked the same job that your grandfather worked 40 years ago. Today, you would need a much higher salary to maintain the same quality of living. By the same token, a homebuyer looking for homes 10 years ago in the $300,000 to $350,000 price range had more and better options to consider than people have now in the same price range.

When a currency’s purchasing power decreases due to excessive inflation, serious negative economic consequences can arise. These can include a higher 澳洲幸运5开奖号码历史查询:cost of living, higher interest rates that affect the global market, and 澳洲幸运5开奖号码历史查询:falling credit ratings. All of these f🥀♐actors can contribute to an economic crisis.

Purchasing Power and CPI

Governments institute policies and regulations to 澳洲幸运5开🐻奖号码历史🅠查询:protect a currency’s purchasing power and keep an economy healthy. They also monitor economic data to stay on top of changing conditions. For example, the 澳洲幸运5开奖号码历史查询:U.S. Bureau of Labor Statistics (BLS) measur𝕴es price changes and announces those changes with CPI.

CPI is one of the measures of inflation and purchasing power. It calculates the change in the weighted average of prices of consumer goods and services, and in particular, transportation, food, and medical care, at a given time. CPI can point to changes in the cost of living as well as 澳洲幸运5开奖号码历史查询:deflation.

The CPI is just one off🔥icial measure of purchasing power in the U.S.

Purchasing Price Parity

A concept related to purchasing power is 澳洲幸运5开奖号码历史查询:purchasing power parity (PPP). PPP is an economic theory that estimates the amount by which an item 澳洲幸运5开奖号码历史查询:should be adjusted for parity, given two countries’ exchange rates. PPP can be used to compare countries’ economic activity, income levels, an🏅d other relevant data concerning the cost of living, or possible rates of 📖inflation and deflation.

The World Bank's International Comparison Program releases data on purchasing power parities between different countries.

Purchasing Power Loss or Gain

澳洲幸运5开奖号码历史查询:Purchasing power loss or gain refers to the decrease or increase in how much consumers can buy with a given amount of money. Consumಌers lose purchasing power when prices increase. They gain purchasing power when prices de๊crease.

Causes of purchasing power loss can include government regulations, inflat🔴ion, and natural and human-made disasters. Causes of purchꦡasing power gain include deflation and technological innovation.

One example of purchasing power gain would be if laptop computers that cost $1,000 two years ago cost $500 today. In the absence of inflation, $1,000 will now buy a lap🌜top plus an additional $500 worth of goods.

Examples of Purchasing Power Loss

Germany After WWI

Historical examples of severe inflation and hyperinflation🏅—which can destroy a currency’s purchasing power—show us the various causes and effects of such phenomena. Sometimes, expensive and de🎶vastating wars will cause an economic collapse, particularly for the losing country. This happened to Germany after World War I (WWI).

In the aftermath of WWI during the 1920s, Germany experienced extreme economic ❀hardship and almost unprecedented hyperinflation, due in part to the enormous amount of reparations Germany had to pay.

Unable to pay these reparations with the suspect German mark, Germany printed paper notes to buy foreign currencies, resulting in high inflation rates that rendered the German mark valueless, with a nonexistent purchasing power.

The 2008 Financial Crisis

The effects of the loss of purchasing power in the aftermath of the 澳洲幸运5开奖号码历史查询:2008 global financial crisis and the European sovereign debt crisis are remembered to this day. Due to increased 澳洲幸运5开奖号码历史查询:globalization and the introduction of the euro, currencies are inextricably linked, and economic trouble can cross geographic boundaries. As a result, governments worldwide institute policies to control inflation, protec🔯t purchasing power, and prevent recessions.

For example, in 2008, the 澳洲幸运5开奖号码历史查询:U.S. Federal Reserve kept interest rates near zero and instituted a plan called 澳洲幸运5开奖号码历史查询:quantitative easing (QE). Quantitative easing, initially controversial, saw the U.S. 澳洲幸运5开奖号码历史查询:Federal Reserve System (Fed) buy government and other market securities to increase the money supply and lower interest rates.

The increase in capital spurred increased lending and created more 澳洲幸运5开奖号码历史查询:liquidity. The U.S. stopped its pol♉icy of quantitative easing once the🔥 economy stabilized.

The 澳洲幸运5开奖号码历史查询:European Central Bank (ECB) also pursued quantitative easing to help stop deflation in the eurozone after the European sovereign debt crisis and bolster the euro's purchasing power. The 澳洲幸运𝔍5开奖号码历史查询:European Economic and Monetary Union established strꦇict regulations in the eurozone related to accurately reporting sovereign debt, inflation, and other financial data.

As a general rule, countries attempt to keep inflation fixed at a rate of 2%. Moderate levels of inflꦗation are acceptable. High levels of deflation🤡 can lead to economic stagnation.

Special Considerations

I♋nvestments That Protect Against Pur꧋chasing Power Risk

Retirees can be particularly aware of purchasing power loss since many of them live off of a fixed amount of money. They must make sure that their investments earn a 澳洲幸运5开奖号码历史查询:rate of return equal to or greater than the rate of inflation so that the value of their nest egg does not decrease each year.

Debt securities and investments with fixed rates of return are the most susceptible to purchasing power risk or inflation. Fixed annuities, 澳洲幸运5开奖号码历史查询:certificates of deposit (CDs), and Treasury bonds all fall into this category. For inst𝓀ance, a long-term bond with a low fixed rate of return might fail to increase your investment during periods of inflation.

Some investments or investing strategies can help 澳洲幸运5开奖号码历史查询:protect 𒈔investo💞rs against purchasing power risk. For example, 澳洲💃幸运5开奖号码历史查询:Treasury inflation𓂃-protected securities (TIPS) adjust to keep up with rising prices. Commodities such as oil and metals may maintain pricing power during pဣeriods of inf♕lation.

The Bottom Line

Long-time investors know that loss of purchasing power can greatly impact their investments. Risi𒆙ng inflation affects purchasing power by decreasing the number of goods or services🀅 you can purchase with your money.

Investors must look for ways to make a return higher than the current rate of inflation. 𒐪More advanced investors may track international economies for the 🐽potential effect on their long-term investments.
