Inflation: WPI & CPI — Set 10

Correct Answer: B. B. 14 days (provisional)

DPIIT releases provisional WPI data approximately 14 days after the end of the reference month. Final WPI data is released with a two-month lag. For example, January WPI provisional data is released in mid-February. The advance release allows markets and policymakers to track wholesale price trends promptly.

Correct Answer: C. C. 12-24 months

Monetary policy in India has a transmission lag of approximately 12-24 months — that is, a change in the repo rate today may take 1-2 years to fully impact inflation. This long lag makes monetary policy challenging and requires policymakers to be forward-looking. The RBI uses inflation forecasts to guide current policy decisions.

Correct Answer: C. C. Fuel and Light

The Fuel and Light component of India's CPI (weight 6.84%) is most directly affected by global crude oil prices through LPG, kerosene, and electricity costs. However, rising crude oil prices also indirectly affect transport costs which feed into food and miscellaneous categories. India imports ~85% of its crude oil, making CPI highly sensitive to global oil prices.

Correct Answer: B. B. Inland states far from ports with poor supply chains

The correct answer is B. Inland states far from ports with poor supply chains. Inland states (like some northeastern states, Chhattisgarh, or Jharkhand) that are far from major production centres and ports, with relatively underdeveloped supply chains and storage infrastructure, tend to experience higher food inflation. Proximity to production areas and good transport connectivity help moderate food prices. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. B. Food and Beverages component of CPI (Combined)

For monetary policy purposes, the RBI monitors food inflation through the Food and Beverages component of CPI (Combined), which carries the highest weight (45.86%) in the CPI basket. This captures changes in retail food prices faced by both urban and rural households. Elevated food CPI is the primary driver of headline CPI breaching the RBI's 6% upper tolerance band.

Correct Answer: B. B. Quarterly Projection Model (QPM)

The RBI uses the Quarterly Projection Model (QPM) for macroeconomic forecasting, including CPI inflation projections. The QPM is a structural macroeconomic model that captures key transmission channels of monetary policy. RBI also uses the Dynamic Stochastic General Equilibrium (DSGE) framework for medium-term projections published in its Monetary Policy Reports.

Correct Answer: B. B. The percentage point output loss per percentage point reduction in inflation

The sacrifice ratio measures the economic cost of reducing inflation: the percentage point fall in GDP (or rise in unemployment) required to achieve a 1 percentage point reduction in inflation. A higher sacrifice ratio means reducing inflation is more costly to growth. India's sacrifice ratio is estimated at around 0.5-1.5, meaning 0.5-1.5% GDP loss for each 1% inflation reduction.

Correct Answer: B. B. Excess of aggregate demand over aggregate supply at full employment

The inflationary gap is the excess of aggregate demand over aggregate supply at the full employment level of output. When aggregate demand exceeds potential output, the excess purchasing power chases the same quantity of goods, pulling up prices — creating demand-pull inflation. The RBI targets this gap by tightening monetary policy to reduce excess demand.

Correct Answer: B. B. 22.6%

Primary Articles have a weight of approximately 22.62% in India's WPI (2011-12 series). This group includes food articles (weight ~15%), non-food articles (like cotton, oilseeds, weight ~4.3%), and minerals (weight ~2.6%). Food articles in primary group include cereals, pulses, vegetables, fruits, milk, eggs, meat, and fish.

Correct Answer: B. B. Rising capacity utilisation, credit growth, and commodity prices simultaneously

The correct answer is B. Rising capacity utilisation, credit growth, and commodity prices simultaneously. Rising capacity utilisation (economy approaching full production), accelerating credit growth (indicating excess liquidity and demand), and rising commodity prices are simultaneous leading indicators of building inflationary pressure. The RBI monitors these indicators through its Monetary Policy Reports and uses them to determine the forward-looking stance of monetary policy. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.
