Purchasing Power

The purchasing power of a currency is the amount of goods or services that one unit of money can buy. It may weaken over time as a result of inflation. This is because rising prices effectively reduce the amount of goods or services available for purchase. Purchasing power is also known as a currency's purchasing power.

In investment jargon, purchasing power is the monetary amount of credit available to a customer based on the marginable securities in the customer's brokerage account.

Understanding Purchasing Power

Inflation reduces the purchasing power of a currency, resulting in a price increase. To evaluate purchasing power, you would traditionally compare the price of a good or service to a price index, such as the Consumer Price Index (CPI).

Purchasing power impacts every segment of the economy, from commodity consumers to investors and stock prices to regional economic development.

When the purchasing power of a currency falls due to excessive inflation, serious negative economic consequences occur, such as rising costs of goods and services, resulting in high living costs, as well as high interest rates, affecting the global market and ultimately resulting in declining credit ratings.

How Purchasing Power Works?

Purchasing power represents an economy's overall price level as well as the availability of products and services. Assume that the overall level of prices in an economy rises. In that instance, the purchasing power of a particular quantity of money decreases, and it can buy fewer goods and services.

In contrast, if the total level of prices in an economy lowers, the purchasing power of a particular quantity of money rises, allowing it to purchase more goods and services. Inflation and deflation can also have an impact on purchasing power.

It is also influenced by factors such as interest rates and currency exchange rates. Similarly, when interest rates are high, the cost of borrowing money rises, reducing purchasing power. Exchange rates also influence purchasing power parity since a stable native currency increases purchasing power when traveling overseas. Overall, it determines the worth of money in terms of the things and services it can purchase.

Special Considerations

Retirees are especially vulnerable to buying power erosion since many of them live on a fixed income. They must ensure that the rate of return on their assets is equivalent to or greater than the rate of inflation, so that the value of their nest egg does not fall year after year.

Debt securities and fixed-rate investments are the most vulnerable to purchasing power risk or inflation. This category includes fixed annuities, certificates of deposit (CDs), and Treasury bonds. A long-term bond with a low fixed rate of return, for example, may fail to raise your investment during periods of inflation.

Key Takeaways

  • Purchasing power is the amount of products or services that a unit of cash can buy at any particular time.
  • Inflation gradually erodes a currency's purchasing value.
  • Central banks change interest rates to try to keep prices constant and purchasing power intact.
  • The Consumer Price Index (CPI) is one indicator of buying power in the United States.
  • Because globalization has connected currencies more closely than ever before, maintaining purchasing power globally is critical.
