The inflation rate is the percentage change in a country’s price index in a given time period. It is a broad measure of price changes that accounts for a diversified set of goods and services. Inflation is a process of price level adjustments in the economy that can distort relative prices, wages, and rates of return.
A high rate of inflation can hurt companies and investors. When prices rise rapidly, they can make companies uncompetitive by making their products more expensive than those of other countries. High levels of inflation can also depreciate the value of savings and investments, which discourages people from spending money and investing in companies.
Inflation can be driven by several factors, including government policy or excessive printing of money. For example, when a country prints too much money, it can lead to “demand-pull” inflation that drives up demand and raises prices.
While the effects of a single price increase may not be significant, a sustained high inflation rate can create hard-to-control “spirals” where one increase feeds subsequent increases. Inflation can also affect the purchasing power of consumers, which is why governments often try to keep it at low levels.
In the United States, there are two main measures of inflation: the Consumer Price Index (CPI), which measures the cost of items that urban consumers buy out of pocket, and the Personal Consumption Expenditures (PCE) price index, published by the Bureau of Economic Analysis. Both of these are monitored closely by economists.
