What is Deflation?

by

Bargain shoppers know there’s nothing better than a price drop. But a one-off sale is a world away from deflation, which is the general reduction of prices for thousands of everyday goods and services.

Not only does deflation signal a stagnating economy, it can lead to high unemployment, unaffordable debt repayment, and dismal outcomes for businesses. In the worst cases, deflation can lead an economy into a recession, or even a depression.

Deflation Definition

Just like inflation, deflation is a story of supply and demand. But instead of prices for goods and services going up over time, they go down. Generally, this means purchasing power increases — people are able to buy more with the same amount of money.

Deflation often comes as a relief to consumers in the short term, but a prolonged period of deflation can be a major roadblock to economic growth.

How is Deflation Measured?

The Consumer Price Index, or CPI, tracks the prices of about 80,000 items on sale in the United States (plus sales or excise taxes) each month. There are also sub-indexes that measure prices in various regions and cities throughout the country.

There are eight major groups represented in the CPI:

Food and beverages
Housing (rents only)
Apparel
Medical care
Transportation (including fuel costs)
Recreation
Education and communication
Other goods and services

Items that aren’t included in the CPI are income taxes, Social Security taxes, stocks, bonds, real estate, and life insurance because they aren’t related to everyday consumption.

When prices rise month to month or year to year, they’re represented by a positive percentage. For example, from May 2021 to May 2022, the index for all items rose 9.1%. If the inflation rate a few months later is 4%, that represents disinflation — prices are dropping, but still showing overall growth. Deflation, by contrast, doesn’t occur until the inflation rate is below 0%.

What Causes Deflation?

As with inflation, deflation is typically caused by a change in government policy and consumers’ reactions to it. It can be difficult to isolate a single driver of rising or falling prices in the middle of the trend. Even years later, the causes are often found to be multi-faceted.

Here are three common scenarios that can lead to deflation:

Decrease in the money supply: When the Federal Reserve deploys a tight monetary policy, that means it’s pulling back on spending and raising interest rates. This makes it harder for people to borrow money to buy goods and services.
Decline in consumer demand: When demand falls, whether because the government is tightening its purse strings or the stock market is on a downswing and investors are hoarding more cash, businesses may lower prices to encourage people to spend.
Increase in business productivity: Technological advances can help businesses produce more goods at a lower cost, increasing the supply on the shelves. With increased supply and level demand, prices fall (think about how cheap TVs have become).

The Effects of Deflation

Deflation isn’t all bad. In the short term, it can help consumers buy more with the same paycheck. Beyond that, the negative effects can mount quickly. Here are a few.

Falling incomes/higher unemployment: When businesses are selling goods for lower prices, they earn less profit. To make up for it, they may cut wages or lay off employees, and spend less on innovation and investing in the company.
Less consumer spending: If consumers have less income to spend, they buy fewer discretionary goods and services. Less overall spending weakens the economy, furthering a deflationary spiral. Another theory for reduced consumer spending is that perception drives outcomes — when prices are continuously dropping, people may save money and put off big purchases to hold out for a lower price tag in the future.
More expensive debt: If the monthly payment on your mortgage or car loan stays the same, but your income falls, you’re spending more of your paycheck on debt. At the same time, the asset you’re paying off — like a house or a car — is dropping in value.

FAQs

What is deflation in simple words?

Deflation is when prices for goods and services decrease over a period of time instead of increasing, as with inflation.

What is deflation and why is it bad?

Deflation is when the inflation rate is below 0%. It’s bad, in part, because it can lead consumers to spend less now, in part because they expect prices to continue to fall; it can push businesses to lower wages or lay off employees to maintain profit levels; and it makes existing debt more expensive for many borrowers.

What happens if there is deflation?

You may see interest rates go down if there is deflation. This is a move by the Federal Reserve to stimulate growth in the economy by encouraging people to borrow and spend money. When there is more demand and a stable supply, businesses can begin to raise prices.

Is deflation worse than inflation?

Deflation is often tougher to combat than inflation, because the Federal Reserve’s biggest lever — interest rates — is limited. In a deflationary environment, the Fed wants to get people to spend more money, so it makes access to credit cheaper. It can’t get any cheaper than a 0% interest rate.

In an inflationary environment, the Fed basically has no ceiling for raising interest rates to tame high prices, though doing so can come with its own set of negative consequences.

Can deflation be a good thing?

Deflation can be helpful if it’s brought on by positive factors, such as technological advances that help businesses increase production. But that kind of modernization generally leads to deflation in one industry or category of goods at a time. When prices fall across the board simultaneously, it may be difficult to control.
