India, a rapidly growing economy, faces increasing scrutiny over its debt-to-GDP ratio. While the general government debt (Centre and States combined) reached approximately 81% in 2022-23, a significant rise from pre-pandemic levels and a peak of 88% in FY21, the International Monetary Fund (IMF) has projected this figure could touch 100% under adverse circumstances by fiscal 2028. This trajectory raises important questions about the long-term sustainability and potential ramifications for the Indian economy, especially when considering that the threshold level for India, beyond which debt can adversely affect growth, is estimated to be around 61%.

However, an RBI research paper offers a more optimistic outlook, projecting a decline in the general government debt-to-GDP ratio to 73.4% by 2030-31, provided stringent fiscal tightening measures are implemented. Trading Economics also forecasts a moderation, expecting the ratio to be around 80% by the end of 2025, further decreasing to 77% by 2027.

Key Consequences of a High Debt-to-GDP Ratio for India:

A high debt burden can lead to several adverse economic outcomes, directly impacting India's growth and development:

• Increased Debt Servicing Costs: As debt levels rise, so do the interest payments, consuming a larger portion of government revenue. In India, interest payments often exceed government spending on critical sectors like education and healthcare, limiting resources for vital public services.
• Reduced Fiscal Flexibility: High debt levels constrain the government's ability to implement countercyclical fiscal policies during economic downturns or respond effectively to unforeseen emergencies.
• Crowding Out Private Investment: When the government heavily borrows from domestic markets, it can increase competition for available funds, potentially raising interest rates and making it more expensive for the private sector to borrow and invest, thereby hindering economic growth.
• Inflationary Pressures and Currency Risks: Excessive government borrowing, especially if financed by printing more money, can lead to inflation, eroding the purchasing power of citizens. Furthermore, with over 54% of India's external debt denominated in U.S. dollars, a depreciating rupee significantly increases the cost of servicing this debt, posing currency volatility risks.
• Lower Sovereign Credit Ratings: Persistently high deficits and debt levels can lead to downgrades in sovereign credit ratings by international agencies. This, in turn, increases the cost of external commercial borrowing, making it more expensive for India to raise funds from international markets.
• Suboptimal Resource Allocation: There is a risk of misallocating borrowed funds into projects that do not yield expected returns, leading to "white elephant projects" and inefficient use of public resources.

India's Unique Position and Challenges:

Despite these concerns, India possesses certain characteristics that contribute to the sustainability of its debt. A significant portion of India's debt is denominated in domestic currency, and the country benefits from a large domestic investor base, which mitigates external currency risks and provides a buffer against global financial shocks. Historically, India has also demonstrated an ability to sustain debt at relatively high levels without experiencing default or restructuring.

However, specific challenges persist:

• State-Level Fiscal Health: The Fiscal Health Index 2025 highlights significant fiscal challenges in several Indian states, including Punjab, West Bengal, Andhra Pradesh, and Kerala. These states often struggle with poor debt sustainability, high fiscal deficits, and low-quality expenditure, raising concerns about structural imbalances in India's fiscal federalism. Some states have been observed to prioritize fiscal prudence at the potential cost of public welfare, creating a "fiscal health mirage."
• Growth-Debt Disconnect: Critics point out that continuous increases in debt have not always translated into improved socio-economic indicators, raising questions about the efficiency of government spending.
• External Debt Management: While India's external debt-to-GDP ratio decreased to 18.7% in March 2025, its rising magnitude and servicing obligations remain a concern amidst global economic uncertainties.

In conclusion, while India's robust economic growth and unique debt structure provide some resilience, continued vigilance and prudent fiscal management are paramount. The path ahead requires a delicate balance between financing developmental needs and ensuring long-term fiscal stability to avoid the potential pitfalls of an unsustainable debt burden.
