Why this matters now
Public debt, deficit financing and debt sustainability are core GS-3 public-finance topics, closely tied to the Budget, FRBM and crowding-out debates.
How the government borrows
The fiscal deficit (the gap between total expenditure and total revenue, excluding borrowings) is financed mainly by borrowing — issuing Government Securities (G-secs/dated securities) and Treasury Bills, plus small savings and external loans. The RBI manages government borrowing as the government’s debt manager and banker.
Public debt — internal & external
Public debt is the total accumulated government borrowing. It is internal (rupee debt, the bulk — owed domestically) and external (foreign-currency debt). India’s public debt is largely internal and rupee-denominated, which limits external-currency risk. The key metric is the debt-to-GDP ratio.
Debt sustainability & FRBM
Debt is sustainable if it grows slower than the economy (so debt/GDP is stable or falling). High debt risks crowding out private investment, high interest payments (a big budget item), and reduced fiscal space. The FRBM Act sets fiscal-discipline targets (deficit and debt) to keep public finances sustainable.
UPSC angle
Know deficit financing (G-secs/T-Bills, RBI as debt manager), public debt (internal — mostly rupee — vs external), debt-to-GDP, debt sustainability (crowding out, interest burden), and the FRBM framework.
