What Is a Price Level?

A price level is the average of current prices across the entire spectrum of goods and services produced in the economy. In more general terms, price level refers to the price or cost of a good, service, or security in the economy.

Price levels may be expressed in small ranges, such as ticks with securities prices, or presented as a discrete value such as a dollar figure.

In economics, price levels are a key indicator and are closely watched by economists. They play an important role in the purchasing power of consumers as well as the sale of goods and services. it also plays an important part in the supply-demand chain.

Understanding Price Levels

There are two meanings of the term price level in the world of business.

The first is what most people are accustomed to hearing about: the price of goods and services or the amount of money a consumer or other entity is required to give up to purchase a good, service, or security in the economy. Prices rise as demand increases and drop when demand decreases.

This is used as a reference to inflation and deflation, or the rise and fall of prices in the economy. If the prices of goods and services rise too quickly—when an economy experiences inflation—a central bank can step in and tighten its monetary policy and raises interest rates. This, in turn, decreases the amount of money in the system, thereby decreasing aggregate demand. If prices drop too quickly, the central bank can do the reverse: loosen its monetary policy, thereby increasing the economy's money supply and aggregate demand.

The other meaning of price level refers to the price of assets traded on the market such as a stock or a bond, which is often referred to as support and resistance. As in the case of the definition of price in the economy, demand for the security increases when its price drops. This forms the support line. When the price increases, a sell-off occurs, cutting off demand. This is where the resistance zone lies.

Price Levels in the Economy

In economics, price level refers to the buying power of money or inflation. In other words, economists describe the state of the economy by looking at how much people can buy with the same dollar of currency. The most common price level index is the consumer price index (CPI).

The price level is analyzed through a basket of goods approach, in which a collection of consumer-based goods and services is examined in aggregate. Changes in the aggregate price over time push the index measuring the basket of goods higher. Weighted averages are typically used rather than geometric means. Price levels provide a snapshot of prices at a given time, making it possible to review changes in the broad price level over time. As prices rise (inflation) or fall (deflation), consumer demand for goods is also affected. This leads to broad production measures such as gross domestic product (GDP) higher or lower.

Price levels are one of the most watched economic indicators in the world. Economists widely believe that prices should stay relatively stable year to year so they don't cause undue inflation. If price levels rise too quickly, central bankers or governments look for ways to decrease the money supply or the aggregate demand for goods and services.

Although prices change gradually over time during inflationary periods, they can change more than once a day when an economy experiences hyperinflation.

Key Takeaways

  • The price level is the average of the current price of goods and services produced in the economy.
  • Price levels are expressed in small ranges or as discrete values such as dollar figures.
  • Price levels are a leading indicator in the economy; rising prices indicate higher demand leading to inflation, while declining prices indicate lower demand or deflation.
  • In the investment world, the price level is referred to as support and resistance, which help define entry and exit points.

Price Level in the Investment World

Traders and investors make money by buying and selling securities. They buy and sell when the price reaches a certain level. These price levels are referred to as support and resistance. Traders use these areas of support and resistance to define entry and exit points.

Support is a price level where a downtrend is expected to pause due to a concentration of demand. As the price of a security drops, demand for the shares increases, forming the support line. Meanwhile, resistance zones arise due to a sell-off when prices increase.

Once an area or zone of support or resistance is identified, it provides valuable potential trade entry or exit points. This is because, as a price reaches a point of support or resistance, it will do one of two things: bounce back away from the support or resistance level, or violate the price level and continue in its direction until it hits the next support or resistance level.
