17.4 Indian Economy Essentials: National Income, Inflation, Fiscal Indicators, GST & External Sector

Exam Focus: General/Financial Awareness questions often test the concepts behind economic news: what GDP measures, which index tracks inflation, what the fiscal deficit target is, how GST is structured, and what makes up forex reserves. This section explains those concepts with the latest verified figures.

1. National Income Concepts

TermDefinition
GDP (Gross Domestic Product)Value of all final goods and services produced within the country's borders in a period
GVA (Gross Value Added) at basic pricesValue of output minus intermediate consumption, before product taxes
GDP at market pricesGVA at basic prices + product taxes − product subsidies
GNP (or GNI)GDP + net factor income from abroad
NDPGDP − depreciation (consumption of fixed capital)
NNP at factor cost (National Income)NNP at market prices − net indirect taxes
Nominal vs. real GDPNominal GDP uses current prices; real GDP uses constant base-year prices
GDP deflator(Nominal GDP ÷ Real GDP) × 100

Base year: The National Statistics Office (NSO) of the Ministry of Statistics and Programme Implementation released the new GDP series with base year 2022-23 on February 27, 2026, replacing the 2011-12 base.

Worked Example

Suppose, in Rs. lakh crore: GVA at basic prices = 300, product taxes = 35, product subsidies = 5, net factor income from abroad = −6, and depreciation = 36.

  1. GDP at market prices = 300 + 35 − 5 = 330
  2. GNP at market prices = 330 + (−6) = 324
  3. NNP at market prices = 324 − 36 = 288

2. Inflation and Its Measures

IndexCompiled byCurrent baseWhat it covers
Consumer Price Index (CPI)NSO, MoSPI2024 = 100 (first released February 12, 2026)Retail prices of goods and services; headline CPI is the RBI's inflation target
Wholesale Price Index (WPI)Office of the Economic Adviser, DPIIT2022-23 = 100 (new series from June 2026)Wholesale prices of goods
Index of Industrial Production (IIP)NSO, MoSPI2022-23 (new series announced for release on May 28, 2026)Volume of industrial output; it is not an inflation index

Key Inflation Terms

  • Headline inflation: Change in the overall CPI, including food and fuel.
  • Core inflation: Inflation excluding volatile food and fuel items.
  • Demand-pull inflation: Prices rise because demand outpaces supply.
  • Cost-push inflation: Prices rise because production costs such as wages, fuel and raw materials increase.
  • Disinflation: Inflation is still positive but falling.
  • Deflation: The general price level falls.
  • Stagflation: High inflation combined with stagnant growth and high unemployment.

The RBI's target is 4% CPI inflation within a 2%–6% band for April 2026 to March 2031 (Section 15.2).


3. Fiscal Indicators in the Union Budget 2026-27

IndicatorFigure
Fiscal deficit, 2025-26 (Revised Estimate)4.4% of GDP
Fiscal deficit target, 2026-27 (Budget Estimate)4.3% of GDP
Central Government debt, 2025-26 (Revised Estimate)56.1% of GDP
Central Government debt, 2026-27 (Budget Estimate)55.6% of GDP
Debt goalAbout 50 ± 1% of GDP by March 31, 2031
Capital expenditure, 2026-27 (Budget Estimate)Rs. 12.2 lakh crore

From 2026-27, the Centre uses the debt-to-GDP ratio as its fiscal anchor, setting each year's deficit so that debt keeps declining. The formulas for revenue, fiscal and primary deficits are in Section 17.2.


4. Goods and Services Tax (GST)

FeatureDetails
Constitutional basis101st Constitutional Amendment Act, 2016
LaunchJuly 1, 2017
NatureDestination-based tax on the consumption of goods and services
Intra-state supplyCGST (Centre) + SGST or UTGST (State or Union Territory)
Inter-state supply and importsIGST, collected by the Centre and apportioned
GST CouncilConstitutional body under Article 279A, chaired by the Union Finance Minister; each State nominates its finance or taxation minister (or another minister) as a member
GST 2.0 (from September 22, 2025)Two main rates of 5% and 18%, plus 40% for select luxury and sin goods; the 12% and 28% slabs were removed after approval at the 56th GST Council meeting on September 3, 2025 (certain tobacco products initially stayed on their earlier rates)

5. External Sector

Balance of Payments (BoP)

AccountMain components
Current accountMerchandise trade (exports and imports of goods), services trade, primary income (investment income and compensation of employees) and secondary income (mainly remittances)
Capital and financial accountForeign direct investment (FDI), foreign portfolio investment (FPI), external commercial borrowings, banking capital including NRI deposits, and other flows
Errors and omissionsStatistical balancing item
Change in reservesThe net result, reflected in foreign exchange reserves

A current account deficit (CAD) means payments for goods, services and income exceed receipts; it must be financed by capital inflows or by drawing down reserves.

FDI vs. FPI

A foreign investment of 10% or more of a listed company's post-issue paid-up equity is treated as FDI; below 10% it is FPI. FDI is long-term and carries management interest, while FPI is more mobile and sensitive to market conditions.

Foreign Exchange Reserves

India's reserves, managed by the RBI, have four components:

  1. Foreign Currency Assets (the largest component)
  2. Gold
  3. Special Drawing Rights (SDRs)
  4. Reserve Tranche Position with the IMF

Exchange Rate Terms

  • Depreciation / appreciation: A market-driven fall or rise in the rupee's value.
  • Devaluation / revaluation: A deliberate official change under a fixed exchange rate system.
  • India follows a market-determined exchange rate, and the RBI intervenes to curb excessive volatility.

Common Traps

  • GDP counts only final goods and services; adding intermediate goods double counts.
  • WPI covers goods only, while CPI covers both goods and services.
  • Disinflation (inflation falling but still positive) is not deflation (prices actually falling).
  • FDI and FPI flows belong to the capital and financial account, not the current account.
