# Disinflation: Definition, How It Works, Triggers, and Example

## What Is Disinflation?

Disinflation is a temporary slowing of the pace of [price inflation](https://www.investopedia.com/terms/p/price_inflation.asp) and is used to describe instances when the inflation rate has reduced marginally over the short term.

### Key Takeaways

*   Disinflation is a temporary slowing of the pace of price inflation. The term is used to describe occasions when the inflation rate has reduced marginally over the short term.
*   Unlike inflation and deflation, which refer to the direction of prices, disinflation refers to the rate of change in the rate of inflation.
*   A healthy amount of disinflation is necessary since it prevents the economy from overheating.
*   The danger that disinflation presents is when the rate of inflation falls near to zero, as it did in 2015, raising the specter of deflation.
*   Disinflation has reemerged in 2023 after inflation reached its highest levels in four decades last year.

## Understanding Disinflation

Disinflation is commonly used by the Federal Reserve (Fed) to describe a period of slowing [inflation](https://www.investopedia.com/terms/i/inflation.asp). It should not be confused with [deflation](https://www.investopedia.com/terms/d/deflation.asp), which can be harmful to the economy. Unlike inflation and deflation, which refer to the direction of prices, disinflation refers to the rate of change in the rate of inflation.

Disinflation is not considered problematic because prices do not actually drop, and disinflation does not usually signal the onset of a [slowing economy](https://www.investopedia.com/terms/g/growthrates.asp). Deflation is represented as a negative growth rate, such as -1%, while disinflation is shown as a change in the inflation rate—say, from 3% one year to 2% the next. Disinflation is considered the opposite of [reflation](https://www.investopedia.com/terms/r/reflation.asp), which occurs when a government stimulates an economy by increasing the money supply.

A healthy amount of disinflation is necessary since it represents economic [contraction](https://www.investopedia.com/terms/c/contraction.asp) and prevents the economy from [overheating](https://www.investopedia.com/terms/o/overheated_economy.asp). As such, instances of disinflation are not uncommon and are viewed as normal during healthy economic times. Disinflation benefits certain segments of a population, such as people who are inclined to save their earnings.

## Disinflation Triggers

Several things can cause an [economy](https://www.investopedia.com/terms/e/economy.asp) to experience disinflation. If a central bank decides to impose a tighter [monetary policy](https://www.investopedia.com/terms/m/monetarypolicy.asp) and the government starts to sell off some of its securities, it could reduce the [supply of money](https://www.investopedia.com/terms/m/moneysupply.asp) in the economy, causing a disinflationary effect.

Similarly, a contraction in the [business cycle](https://www.investopedia.com/terms/b/businesscycle.asp) or a [recession](https://www.investopedia.com/terms/r/recession.asp) can also trigger disinflation. For example, businesses may choose not to increase prices to gain greater [market share](https://www.investopedia.com/terms/m/marketshare.asp), leading to disinflation.

## Disinflation Since 1980

The U.S. economy experienced one of its longest periods of disinflation from 1980 through 2015.

During the 1970s, the rapid rise of inflation came to be known as the [Great Inflation](https://www.investopedia.com/articles/economics/09/1970s-great-inflation.asp), with prices increasing more than 110% during the decade. The annual rate of inflation topped out at 14.76% in early 1980.

Following the implementation of aggressive monetary policies by [the Fed](https://www.investopedia.com/terms/f/federalreservebank.asp) to reduce inflation, the increase in prices slowed in the 1980s, rising just 59% for the period. In the 1990s, prices rose 32%, followed by a 27% increase from 2000 to 2009 and a 9% increase from 2010 to 2015.

During this period of disinflation, stocks performed well, averaging 8.65% in [real returns](https://www.investopedia.com/terms/r/realrateofreturn.asp) from 1982 through 2015. Disinflation also allowed the Fed to lower interest rates in the 2000s, which led to [bonds](https://www.investopedia.com/terms/b/bond.asp) generating above-average returns.

Here is the danger that disinflation presents: When the rate of inflation falls near to zero, as it did in 2015, it raises the specter of deflation. Although the rate of inflation was near zero in 2015, concerns over deflation were dismissed because it was largely attributed to falling energy prices. As energy prices recovered in the period from 2016 to 2020, the rate of inflation picked up somewhat, averaging 1.8% during that period—moderated in 2020 by the COVID-19 pandemic.

## Disinflation Returns

Disinflation has reappeared in 2023, following inflation jumping to its highest level in four decades last year. Since the [Consumer Price Index (CPI)](https://www.investopedia.com/terms/c/consumerpriceindex.asp) peaked at 9.1% in June 2022, the closely watched metric, which measures the overall change in consumer prices, has retreated. However, inflation still sits at historically high levels, well above the Federal Reserve’s target of 2%. 

A Boston University research paper published in the mid-2000s, examining a sustained period of disinflation in the early 1980s under then-Fed chair [Paul Volcker](https://www.investopedia.com/terms/v/volcker-rule.asp), provides perhaps the best indication of how the economy will perform in 2023 under similar conditions to those years.

When Volcker assumed his position in mid-1979, he aggressively lifted the [federal funds rate](https://www.investopedia.com/terms/f/federalfundsrate.asp) to tackle rampant inflation, which sat at 9%. In the following years, the economy cooled substantially, experiencing two recessions from 1980 to 1983, with unemployment climbing to 10.8% by the end of 1982. Current chairman Jerome Powell has lifted [interest rates](https://www.investopedia.com/terms/i/interestrate.asp) over the past 12 months at the fastest rate since Volcker to tame inflation, indicating a possible economic downturn if history repeats after a period of [hawkish](https://www.investopedia.com/terms/h/hawk.asp) monetary policy.

## How Is Disinflation Different from Deflation?

The key difference between disinflation and deflation is that the former is always _positive_ but decreasing, while the latter is always _negative_.

## What Causes Disinflation?

Disinflation is usually caused by contractionary monetary policy—e.g., rising interest rates. It can also arise from increases in productivity and technology.

## What Happens to the Economy During Periods of Disinflation?

Past periods of disinflation have caused [recessions/economic slowdowns](https://www.investopedia.com/forecasts-cloudy-for-rest-of-2023-7556137) that resulted in higher [unemployment](https://www.investopedia.com/terms/u/unemployment.asp) and lower [corporate earnings](https://www.investopedia.com/terms/e/earnings.asp).

## What Happened to the Economy During the Last Period of Disinflation?

Academic research shows that the economy suffered two recessions and higher unemployment during the last sustained period of disinflation, in the early 1980s.

## The Bottom Line

Disinflation refers to a slowing in the rate of inflation, typically when it eases over the short term. Proponents of disinflation argue that it’s necessary to prevent the economy from overheating, while opponents say that it can lead to a downturn or cause deflation, as it represents economic contraction.

Disinflation typically arises from a reduction in the money supply that results from rising interest rates, but it can also come about by productivity advancements or companies raising prices at a slower pace during a contracting business cycle. A period of disinflation in the early 1980s indicates the economy may contract over the next few years if history repeats.
