Price Inflation: Definition, Measures, Types and Pros and ConsThe simple definition is a general rise in prices. The classic definition is ‘too much money chasing too few goods.’
Inflation news has been dominating the headlines for several months as the global economy begins to slowly reopen following the more than year-long pandemic. The rapid rise in prices has become a top concern as central bankers, consumers and investors fret about the rising cost of groceries, housing, gasoline, and other living expenses. The most immediate way inflation is felt by consumers is the negative effect on purchasing power and quality of life.

What is Inflation?
The simple definition is a general rise in prices. The classic definition is “too much money chasing too few goods.” The price of individual items fluctuates all the time so it takes a collection of items rising at the same time to drive the inflation meter higher.
CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. The vast majority of retail investor accounts lose money when trading CFDs. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.
How is Inflation Measured?
Probably the best-known measure of inflation in the U.S. is the Consumer Price Index (CPI), which measures the average change in prices paid by urban consumers for things like food, clothes, housing, and transportation. The Federal Reserve measures inflation by the personal consumption expenditure (PCE) price index. While CPI looks at what people are buying, PCE looks at what businesses are selling.
Core inflation is another term that is tossed around quite often. It takes into consideration all inflation minus food and energy, which tend to be volatile. They can be influenced by oil supply and weather, and since the events can be deemed as short-term, their numbers are stripped out of the total inflation picture.
Cost-Push Inflation vs. Demand-Pull Inflation: What’s the Difference?
Cost-push inflation is not that common. It starts with a decrease in total supply or an increase in the cost of that supply. Suppliers raise prices because they know consumers will pay it.
Demand-pull inflation exists when aggregate demand for a good or service outstrips aggregate supply. It begins with an increase in consumer demand. Sellers meet such an increase with more supply. But when additional supply is unavailable, sellers raise their prices. (Learn more about cost-push and demand-pull inflation here.)
Why Should I Care About Inflation? (Pros and Cons)
It’s the Fed’s job to calm people’s nerves over inflation. Generally speaking, consumers don’t worry about inflation being too low.
Throughout April and May 2020 at the start of the pandemic when prices were plunging, consumers weren’t fretting over low food and gasoline prices. They were focused on avoiding coronavirus. While quarantined, and with the economy on lockdown, fewer people were driving and gasoline and crude oil prices fell sharply.
Now that most of the lockdowns have ended, more people are working and individuals are driving and flying. This is driving up gasoline and crude oil prices. In other words, prices are reflating from extremely low levels in early 2020 to higher prices in the Spring/Summer of 2021.
Historically low-interest rates are also helping to drive inflation higher. When the economy was stable in early 2020 before the pandemic, mortgage rates were relatively stable but higher than they are at this time. When the Fed slashed its benchmark rates, mortgage rates fell sharply. Low mortgage rates are one of the factors driving up demand for housing.
Demand for housing is increasing, but the supply of available homes to buy is low so people are building new houses. After a sluggish 2020 drove down demand for building materials such as copper and lumber, the current surge in home building is driving up demand for these materials. The increase in prices is another contributing factor to a rapid rise in inflation.
The Fed sees the rise in gasoline, copper, and lumber prices as a temporary reaction to the reopening of the economy. They don’t see the rise in prices as here to stay. Policymakers can explain away the jump in prices as economic growth. They feel they have the measures to combat inflation, but they also run the risk of stopping growth too fast.
