In short

The IMF and the World Bank are the twin Bretton Woods institutions created in 1944: the IMF lends short-term to countries in balance-of-payments difficulty and polices the international monetary system, while the World Bank Group lends long-term for development projects and reforms. International finance is the wider field of cross-border capital flows, sovereign borrowing, reserves and the institutions that govern them. For India the subject is not academic — the 1991 crisis was resolved with an IMF standby arrangement, and World Bank/ADB/AIIB money still funds Indian highways, metros and health programmes. It is examined in BA/MA Economics international-economics papers, in UPSC and RBI Grade B and NABARD exams, and tested in interviews for banks, rating agencies, policy think tanks and development consultancies.

Formulas and examples

Voting power Vᵢ = (basic votesᵢ + Quotaᵢ in SDR / 100,000) ÷ Σ over all members, expressed as % — basic votes are an equal share for each member of 5.502% of total votes (about 1,460 each); quota in SDR, votes dimensionless.
Quota share sᵢ = Quotaᵢ / Σ Quota × 100 (%) — the base for access limits and SDR allocation.
Quota formula (CQS, 2008 review) CQS = (0.50 × GDP + 0.30 × Openness + 0.15 × Variability + 0.05 × Reserves)k, where GDP is a 60:40 blend of market-exchange-rate and PPP GDP, Openness is average current receipts plus payments, Variability is the variability of current receipts and net capital flows, Reserves is official reserves; k = 0.95 compression factor. All variables are expressed as shares of the global total.
Reserve adequacy — import cover = Foreign-exchange reserves (USD) ÷ Average monthly merchandise (or goods-and-services) imports (USD/month) = months of imports.
Greenspan-Guidotti rule: reserves ≥ short-term external debt at residual maturity (one year), i.e. ratio ≥ 1.
External debt sustainability Debt/GDP ratio change ≈ (r − g)/(1 + g) × previous Debt/GDP − primary balance/GDP, where r = nominal effective interest rate (%), g = nominal GDP growth (%); currency depreciation adds (Δe × share of foreign-currency debt).
SDR value SDR 1 = Σ (currency units in basket × exchange rate of that currency against USD), then converted to any currency at market rates.
Debt service ratio = (Principal + Interest payments on external debt) ÷ Current receipts (exports of goods, services and remittances) × 100 (%).

Example 1 — Voting power from quota. A member has a quota of SDR 13,114.4 million (about India's quota after the 14th Review). Quota-based votes = 13,114.4 million ÷ 0.1 million = 131,144. Adding basic votes of about 1,460 (the member's equal share of 5.502% of total voting power) gives roughly 132,600 votes. If total votes across all members are about 5.05 million, the share = 132,600 ÷ 5,050,000 × 100 ≈ 2.63%. Note the gap from the quota share of about 2.75% — basic votes dilute large members slightly and lift small ones.

Example 2 — Import cover and the 1991 benchmark. Reserves of USD 1.0 billion against monthly imports of about USD 1.75 billion give cover = 1.0 ÷ 1.75 ≈ 0.57 months ≈ 17 days — the 1991 emergency. Compare 2025-26: reserves of about USD 690 billion against monthly merchandise imports of roughly USD 60 billion give 690 ÷ 60 = 11.5 months. The ratio therefore improved by a factor of about twenty, which is why India needed no Fund programme in 2008, 2013 or 2020.

Example 3 — Reserve tranche versus credit tranche access. Suppose a member's quota is SDR 2,000 million and it has paid 25% (SDR 500 million) in reserve assets, of which the Fund holds SDR 400 million of its currency below quota. Reserve tranche position = quota − Fund's holdings of its currency = 2,000 − 1,600 = SDR 400 million, drawable unconditionally. A first-credit-tranche purchase of SDR 500 million (25% of quota) would take total access to SDR 900 million, or 45% of quota, and would require a programme with performance criteria.

Example 4 — Debt sustainability arithmetic. A country has external-debt-to-GDP of 60%, nominal interest rate r = 7%, nominal GDP growth g = 11%, and a primary surplus of 1% of GDP. Change in debt ratio ≈ (0.07 − 0.11)/(1.11) × 60 − 1 = (−0.04 ÷ 1.11) × 60 − 1 = (−0.03604 × 60) − 1 = −2.162 − 1 = −3.16 percentage points, so debt falls to about 56.8% of GDP. If the currency depreciates 10% and 50% of the debt is foreign-currency denominated, add roughly 0.10 × 0.5 × 60 = +3.0 points, nearly cancelling the gain — the classic emerging-market vulnerability.

Example 5 — Debt service ratio. External debt service of USD 55 billion against current receipts of USD 800 billion gives 55 ÷ 800 × 100 = 6.9%, comfortably below the 20-25% range treated as a danger zone. India's ratio has stayed in single digits in recent years (RBI publishes the exact figure each quarter).
