CORE INFLATION:
- Core inflation refers to the change in the prices of goods and services after excluding items that show frequent and sharp price fluctuations, particularly food and energy. These components are excluded because their prices are highly volatile and are often influenced by seasonal factors, weather conditions, geopolitical developments, and supply-side disruptions rather than demand conditions in the economy.
- Food and energy prices are exempted from the calculation of core inflation because their volatility can distort the actual inflationary trend. By removing these fluctuating components, core inflation captures the underlying and long-term movement in the general price level.
- Core inflation is considered a better indicator of persistent inflationary pressures in the economy. It reflects demand-side conditions such as consumption, investment, wage growth, and credit expansion, rather than temporary price shocks.
IMPORTANCE OF CORE INFLATION:
- Core inflation is important because it helps in assessing the real impact of rising prices on consumer income and purchasing power over the long term. It allows policymakers to distinguish between temporary price shocks and sustained inflationary trends.
- Central banks rely on measures of core inflation to filter out short-term and transitory price movements. If the rise in the price index is caused by temporary shocks that are expected to reverse, it may not require immediate monetary policy intervention.
- Prices of goods other than food and fuel generally do not fluctuate frequently. Therefore, an increase in their prices is more likely to be permanent in nature and indicative of sustained inflationary pressure. For this reason, it is logical for central banks to focus on core inflation while framing monetary policy.
- By excluding volatile components from headline inflation, core inflation helps identify the underlying trend in overall inflation. It is also considered a better predictor of future inflation.
- Core inflation serves as a convenient and reliable guide for central banks in achieving their objective of controlling total inflation. Whenever core inflation rises persistently, central banks tend to increase key policy interest rates to absorb excess liquidity from the economy. Conversely, when core inflation moderates, policy rates may be reduced to stimulate economic activity. Hence, core inflation is a preferred indicator for framing long-term monetary policy.
- In India, the Reserve Bank of India closely monitors core inflation while making interest rate decisions under the inflation-targeting framework.
HEADLINE INFLATION:
- Headline inflation refers to the total inflation prevailing in an economy. It is the raw inflation figure that is reported through price indices such as the Consumer Price Index.
- Headline inflation includes price changes in all goods and services consumed by households, including food and energy items. As a result, it reflects the actual inflation experienced by consumers in their day-to-day lives.
- Headline inflation is more sensitive to short-term price fluctuations and supply shocks. While it is important from a welfare and political perspective, it may not always reflect underlying inflationary pressures in the economy.
DIFFERENCE BETWEEN CORE INFLATION AND HEADLINE INFLATION:
- Core inflation excludes food and energy prices to provide a stable measure of long-term inflation, whereas headline inflation includes all goods and services and captures overall price changes in the economy.
- Core inflation is mainly used for monetary policy decisions, while headline inflation is used to assess the cost of living and inflation faced by consumers.
DEFLATION:
- Deflation is defined as a general and sustained decline in the prices of goods and services in an economy. It is usually associated with a contraction in the supply of money and credit.
- During deflation, the purchasing power of money increases over time, meaning that consumers can buy more goods and services with the same amount of currency. However, persistent deflation can be harmful because it discourages consumption and investment, slows economic growth, and increases the real burden of debt.
- Deflation is often considered more dangerous than moderate inflation, as it can lead to prolonged economic stagnation.
