1. Based on the Rate or Speed of Price Rise
- Creeping Inflation: A slow and gradual increase in the general price level, typically up to 2% per year . This is regarded as favorable for an economy because it signals healthy demand, which spurs production, investment, and employment.
- Trotting Inflation: This occurs when the rate of inflation begins to increase, generally exceeding 4% per year. At this stage, the economy starts to “heat up,” leading to a tendency for people to hoard commodities in anticipation of further price rises, which can eventually accelerate into more severe inflation.
- Galloping Inflation: An extraordinarily high rate of inflation, reaching 20% or more. This severely hampers macroeconomic stability, erodes the value of money rapidly, and causes the government to lose credibility.
- Hyperinflation: A rare phenomenon characterized by rapid, excessive, and out-of-control price increases that can reach thousands or millions of percent annually. It usually results from reckless fiscal policies, such as printing massive amounts of money to finance wars.
- Notable historical examples include Post-WWI Germany, where currency was used as stove fuel, and Zimbabwe in 2008, which saw a daily inflation rate of 98%.
2. Based on the Mismatch Between Demand and Supply
- Demand-Pull Inflation: Occurs when the demand for goods and services increases faster than an economy’s productive capacity—essentially “too much money chasing too few goods”.
- Major causes include an increase in the money supply, higher government spending, tax cuts that increase disposable income, and depreciation of local exchange rates that makes exports more attractive
- Cost-Push Inflation: This is triggered by an increase in the cost of producing goods and services.
- It is often caused by rising raw material prices (like crude oil), higher wages, supply chain bottlenecks (such as those seen during COVID-19 lockdowns), or increases in indirect taxes.
- In India, a poor monsoon can also trigger cost-push inflation in food products.
3. Structural and Specialized Types
- Structural (Bottleneck) Inflation: This results from weaknesses in an economy’s structure, such as poor infrastructure or lack of cold storage.
- This is common in developing economies like India, where a disparity exists between what a producer receives and what a consumer pays due to transportation and agricultural bottlenecks.
- Stagflation: A difficult economic state where there is a simultaneous increase in inflation and high unemployment.
- This often leads to a “policy logjam” because attempts to fix one issue (like lowering interest rates to reduce unemployment) may worsen the other (by increasing inflation)
- Core Inflation: A measure of price rise that excludes volatile items like food and energy products (e.g., crude oil).
- Because food and energy prices change rapidly based on factors like rainfall or geopolitics, core inflation is used to reflect the more stable, underlying nature of price rises.
- Open Inflation: A situation in a free market economy where prices fluctuate naturally based on aggregate demand and are not controlled by the government.
4. Opposite and Related Concepts
- Deflation: A consistent decrease in the average price of goods and services, expressed as a negative inflation rate (below 0%).
- It can discourage consumer spending as people wait for lower prices and can lead to high unemployment and revenue loss for companies.
- Disinflation: A slowdown in the growth rate of inflation.
- Unlike deflation, the economy is still growing and inflation is still positive, but it is increasing at a slower pace (for example, falling from 3% to 2%)
- Reflation: A deliberate government policy of providing fiscal stimulus (increasing money supply and lowering taxes) to help an economy recover from a recession.
To understand the spectrum of these types, you can think of inflation like the speed of a car: Creeping is a steady, safe cruise that keeps the engine healthy; Trotting is a brisk pace that starts to strain the parts; Galloping is a dangerous speed where you might lose control; and Hyperinflation is a rocket launch that eventually causes the vehicle to break apart entirely.
