In short

Economic reforms since 1991 are the shift of the Indian economy from a state-directed, licence-based, inward-looking regime to a market-oriented, competitive and globally integrated one — summarised as LPG: liberalisation, privatisation and globalisation. They were triggered by the balance-of-payments crisis of mid-1991 and launched through the New Industrial Policy (24 July 1991) and the Union Budget of 1991-92. They matter because almost every current policy question — GST, inflation targeting, PLI, disinvestment, FDI caps, labour codes — is a continuation or correction of that turn. The topic is examined in BA/MA Economics papers on the Indian economy, in UGC-NET, UPSC and RBI/NABARD/SEBI Grade-B papers, and in interviews for economist, research, policy, consulting, banking and credit-rating roles.

Formulas and examples

Import cover (months) = Foreign exchange reserves ÷ (Annual merchandise imports ÷ 12). Units: both in US$; answer in months.
Rupee depreciation (%) = (E₁ − E₀)/E₀ × 100, where E = ₹ per US$. The fall in the external value of the rupee = (1/E₁ − 1/E₀)/(1/E₀) × 100 — the two differ.
CAGR of real GDP = [(Y_t / Y_0)1/t − 1] × 100, Y in constant prices, t in years.
Fiscal deficit ratio = (Total expenditure − Revenue receipts − Non-debt capital receipts) ÷ Nominal GDP × 100. Primary deficit = Fiscal deficit − Interest payments. Revenue deficit = Revenue expenditure − Revenue receipts.
Debt dynamics: Δd = [(r − g)/(1 + g)] × d + pd, where d = debt/GDP, r = nominal effective interest rate, g = nominal GDP growth, pd = primary deficit/GDP (all as fractions or all as percentages, consistently).
Trade openness = (Exports + Imports) ÷ GDP × 100, same currency throughout.
ICOR = Investment rate (% of GDP) ÷ Real GDP growth (%) ⇒ g = Investment rate ÷ ICOR.
Current account deficit (% of GDP) = CAD ÷ Nominal GDP × 100; BoP identity: Current account + Capital & financial account + Errors & omissions − Reserve change = 0.

1. Import cover in June 1991. Reserves ≈ $1.1 billion; merchandise imports ≈ $24 billion a year → monthly imports = 24 ÷ 12 = $2 billion. Cover = 1.1 ÷ 2 = 0.55 months ≈ 17 days. This is why the crisis was a liquidity emergency, not a slow decline.

2. The July 1991 devaluation. Rate moved from about ₹21.1/$ to ₹25.9/$ (steps of 9% and 11% in the rupee's external value).

3. Long-run growth. If real GDP index rises from 100 (1990-91) to 700 (2023-24), t = 33 years. CAGR = (7)1/33 − 1 = eln7/33 − 1 = e1.9459/33 − 1 = e0.05897 − 1 = 6.07% a year — roughly double the pre-1980 trend. (Illustrative index; use CSO/MoSPI constant-price series for exact values.)

4. Fiscal deficit in rupees. Nominal GDP ≈ ₹357 lakh crore and a fiscal deficit target of 4.4% of GDP → FD = 357 × 0.044 = ₹15.7 lakh crore. If interest payments are ₹12.8 lakh crore, primary deficit = 15.7 − 12.8 = ₹2.9 lakh crore (0.81% of GDP) — i.e. most of the borrowing services past debt. (Budget estimates get revised; check the latest Budget at a Glance.)

5. Does the debt ratio fall? d = 82% of GDP, nominal growth g = 10.5%, effective nominal interest r = 7.0%, primary deficit pd = 1.5% of GDP.

6. Openness and ICOR. Exports ≈ $780 billion, imports ≈ $855 billion (goods + services), GDP ≈ $3,550 billion → openness = 1,635/3,550 × 100 = 46%, against roughly 15% in 1990-91. With an investment rate of 31% of GDP and growth of 7%, ICOR = 31/7 = 4.43; if efficiency worsens to ICOR 5.0, the same investment yields g = 31/5 = 6.2% — a 0.8 pp loss purely from capital productivity.
