Interest payments take a growing share of Union revenue expenditure. Examine the implications for fiscal space and developmental spending.

Interest is the Union's largest committed expenditure. In BE 2026-27 it is set to grow 10.2%, faster than total revenue expenditure (6.6%). It will absorb about 40% of revenue receipts [1]. As its share rises, the government has less money left for development.

Implications for fiscal space

• Revenue already spoken for: about 65.3% of revenue receipts go to salaries, pensions and interest. Only about a third is left for everything else [1].
• The deficit is mostly interest: the fiscal deficit (4.3% of GDP) is far larger than the primary deficit (0.7%). Most new borrowing therefore goes to paying interest on old debt [1].
• Borrowing funds consumption: the government borrows to cover a revenue deficit (1.5% of GDP), so some loans pay for running costs instead of building assets [1].
• Mid-year evidence: up to September 2026, interest of ₹6,46,010 crore was about a quarter of total expenditure and over a third of total receipts [2].
• Thin shock buffer: with so much spending fixed, it is hard to respond to a downturn without leaving the FRBM glide path.

Implications for developmental spending

• Crowding out: interest must be paid first. When receipts fall short, cuts land on discretionary heads such as health, education and rural schemes.
• Capex vs consolidation: public capex rises to ₹12.2 lakh crore [3]. Because it is largely funded by borrowing, it adds to future interest bills.
• Debt–interest loop: Debt stock → Interest bill → Revenue squeeze → Borrowing for capex → Higher debt
• Possible offset: if capex is well chosen, it can lift nominal GDP growth (10% assumed for 2026-27 [1]). Faster growth lowers the debt ratio and can break the loop.

Way forward

• Anchor policy to the debt target, bringing outstanding liabilities down from 55.6% to about 50% of GDP by March 2031 [1].
• Keep the primary deficit low and favour capex that adds most to growth.
• Raise non-debt receipts, for example through the higher ₹80,000 crore disinvestment target [1], and rationalise subsidies.

Rising interest payments shrink fiscal space and tie today's development spending to past borrowing. A credible debt glide path, stronger revenue collection and capex that boosts growth can break this loop. That would leave room for inclusive development, in line with SDG 8 and the FRBM Act's aim of fairness between generations.
