Public Debt in India: Sustainability, Risks, and the Way Forward
Introduction
Public debt is a critical indicator of a country’s fiscal health and long-term economic sustainability. In India, rising public debt has emerged as a major policy concern due to increasing government expenditure, fiscal deficits, and external shocks such as economic slowdowns and pandemics. While public borrowing enables the government to finance development and welfare programmes, excessive debt can constrain fiscal space, increase interest burdens, and pose risks to macroeconomic stability. For UPSC aspirants, public debt is a core GS Paper III topic with strong linkages to fiscal deficit, FRBM Act, inflation, and intergenerational equity.

- Sets debt and deficit targets
FRBM Review Committee
- Recommended debt-GDP ceiling

- Intergenerational equity
- Responsible fiscal governance
High public debt raises ethical questions about fiscal prudence and accountability.
Role of RBI in Debt Management

Conclusion
Public debt plays a crucial role in financing India’s development and responding to economic shocks. However, rising debt levels can constrain fiscal flexibility, increase interest burdens, and pose risks to long-term macroeconomic stability. The key challenge for India lies not in eliminating public debt but in managing it responsibly. Ensuring that borrowings are channelled towards productive capital expenditure, strengthening revenue generation, and maintaining fiscal discipline under the FRBM framework are essential for debt sustainability. Moreover, ethical considerations of intergenerational equity and transparency must guide public borrowing decisions. A balanced and growth-oriented debt management strategy will enable India to harness public debt as a developmental tool rather than allowing it to become a structural vulnerability.
