Core Inflation
Inflation has always been a major economic factor due to its ability to affect all sectors of the economy from business to consumers, often in unpredictable and negative ways. As an economic concept, inflation refers to a sustained increase in the average price of all goods and services in an economy. This could be regarded as balance sheet deflation, as prices increase while coins and paper notes remain the same. Over the years, analysts have sought to understand, measure, and explain the factors behind general inflation, while also pinpointing the fundamental causes of a particular type of inflation known as core inflation.
Core inflation is the measure of inflation that is calculated by removing the volatile consumer products and services, such as food and fuel, from the calculation, since their prices can be volatile and unpredictably affected by external factors. Core inflation, unlike and not to be confused with regular inflation, is more sustainable, since it reflects the underlying fundamentals and not seasonal influences. As such, core inflation is a more accurate and reliable measure of the prices of the goods and services people purchase on a regular basis and the amount of their purchasing power over time.
In countries with a large and diverse economy, monetary policy is able to stabilize the overall economy by selectively targeting core inflation. This helps to ensure that fluctuations in prices of volatile consumer goods and services will not create a long-term trend of increase in the prices of goods and services, which in turn will create a long-term trend of inflation. By targeting core inflation, central banks are able to stabilize the overall currency, secure the financial stability of consumers, and encourage steady economic growth.
When core inflation is rising too quickly, such as over 8%, it is used as an early warning indicator that the central bank must react in order to prevent a downward spiral of prices and wages for businesses, consumers, and government services. It can sometimes be difficult to gauge core inflation accurately, since it is often hidden by volatile consumer goods and services. In order to accurately measure core inflation, analysts must find a way to isolate the inflation rate of goods and services which reflect the underlying financial health of the economy.
In the United Kingdom, the Bank of Englands inflation target is 2%. This is aimed at keeping prices stable and enabling a strong and consistent economic growth. The Office for National Statistics (ONS) uses the Consumer Prices Index (CPI) to measure the prices within the UK economy. The CPI measures the prices of a range of goods and services and includes volatile consumer goods and services such as food, fuel and energy prices. In order to calculate core inflation, the ONS uses the End of Year Index of Consumer Services Prices (EIYICSP), which excludes food and energy prices, to measure the inflation of core goods and services. The EIYICSP allows analysts to measure core inflation without the disruptive influences of volatile products and services.
In conclusion, core inflation is an important measure of inflation which analysts depend on discuss the sustainability of a currency and the overall health of an economy. Core inflation removes the noise created by volatile products and services and reveals the underlying fundamental inflation that is created by current economic conditions. It is a reliable indicator which central banks can use to target their economic policies, in order to keep prices stable, protect consumers and businesses, and encourage economic growth.
