Public Debt

Public Debt

Public Debt refers to the total borrowings of the government — from its own citizens and institutions, as well as from foreign governments and international institutions — undertaken to bridge the gap between its expenditure and its revenue (chiefly to finance a budget deficit) or to fund specific development projects.

Classification of Public Debt.

1. Internal Debt vs External Debt (based on the source of borrowing):
   • Internal Debt is borrowing raised from within the country — from the public (through government bonds/securities), commercial banks, and the Reserve Bank of India. Repayment and interest are made in domestic currency and remain within the domestic economy.
   • External Debt is borrowing raised from sources outside the country — foreign governments, international institutions such as the World Bank and the International Monetary Fund (IMF), and foreign commercial banks/investors. Repayment is typically in foreign currency, and external debt exposes the country to exchange-rate risk.
2. Productive Debt vs Unproductive Debt (based on how the borrowed funds are used):
   • Productive Debt is raised to finance capital/development projects (e.g. building infrastructure) expected to generate future income or returns, out of which the debt can eventually be serviced.
   • Unproductive Debt is raised to meet current, non-development expenditure (e.g. to finance a revenue deficit, or war expenditure) that does not create a corresponding productive asset.

Causes for the Growth of Public Debt in India:

1. Persistent budget deficits, where the government's revenue has fallen short of its expenditure year after year, financed by fresh borrowing.
2. Financing large development and infrastructure projects (irrigation, power, transport) whose scale exceeds what current tax revenue alone can fund.
3. Defence expenditure, particularly during periods of conflict or heightened security spending, which has historically driven sharp increases in borrowing.
4. Rising interest burden, since interest on existing debt itself has to be paid, often partly by taking on fresh debt — a compounding effect.
5. Subsidies and welfare expenditure, where the government borrows to fund food, fertiliser, and fuel subsidies and social-welfare schemes when current revenue is insufficient.
6. Natural calamities and emergencies (droughts, floods, pandemics), which require sudden, large, unbudgeted government spending met through additional borrowing. …
