#1
CPI-Combined (Base Year 2012) serves as the legal anchor for monetary policy, with Food and Beverages carrying the largest weight at 45.86%.
#2
WPI (Base Year 2011-12) monitors manufactured products (64.23%), primary articles (22.62%), and fuel & power (13.15%), entirely excluding services.
#3
Under the Flexible Inflation Targeting (FIT) framework, the statutory target is 4% CPI inflation with a permissible variation band of 2% to 6%.
#4
Core inflation strips out volatile food and fuel categories from headline CPI to assess underlying long-term inflationary pressures.
#5
Stagflation represents an adverse macroeconomic state characterized simultaneously by stagnant economic output, high unemployment, and high inflation.
#6
The Urjit Patel Committee report of January 2014 recommended adopting headline CPI-Combined over WPI as the sole nominal anchor for monetary policy in India.
#7
The National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation releases monthly CPI numbers on the 12th of every month.
#8
The Office of the Economic Adviser under the Ministry of Commerce and Industry compiles and publishes the Wholesale Price Index (WPI) on the 14th of each month.
#9
Demand-pull inflation occurs when aggregate demand exceeds aggregate supply at full employment, classically described as too much money chasing too few goods.
#10
Cost-push inflation arises from adverse supply shocks, such as sudden crude oil price spikes or raw material supply bottlenecks, shifting the aggregate supply curve inward.
#11
Headline inflation measures total inflation within an economy, incorporating volatile sub-components including crude petroleum, pulses, and seasonal vegetable prices.
#12
The GDP Deflator measures the ratio of nominal GDP to real GDP multiplied by 100, capturing price movements across all domestically produced goods and services without import bias.
#13
The Consumer Food Price Index (CFPI) is a sub-component of CPI-Combined tracking retail prices of specific food items consumed by households, carrying a weight of 39.06%.
#14
Under the Monetary Policy Framework Agreement signed on February 20, 2015, failure to maintain the inflation target occurs when average headline inflation remains outside the 2% to 6% band for three consecutive quarters.
#15
The Phillips Curve model illustrates an inverse empirical trade-off between unemployment and inflation in the short run, although the relationship breaks down during stagflation episodes.
Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
Inflation measures how fast prices rise, reducing the purchasing power of households. India tracks price changes through two main indices: the Wholesale Price Index, published by the Office of the Economic Adviser, and the Consumer Price Index, issued by the National Statistical Office. Following the Urjit Patel Committee report, the Reserve Bank of India adopted CPI-Combined as its official anchor under Flexible Inflation Targeting, maintaining a four percent target with a two to six percent tolerance band.
For UPSC, SSC, and banking exams, questions test index compositions and policy mechanics. Keep in mind that WPI excludes services and assigns its greatest weight to manufactured items, whereas CPI covers services and allocates over forty-five percent to food and beverages. A common test trap confuses headline and core inflation: core inflation excludes volatile food and fuel items. Remember that failure occurs if average headline inflation stays outside the target band for three consecutive quarters.
