What is debt service and how does it impact a country’s fiscal space?

• A. Debt service is the cash required to cover interest and principal payments on debt; high debt service can constrain fiscal space.
• B. Debt service is profits from debt instruments; it expands fiscal space.
• C. Debt service is taxes paid on debt interest; it has no effect on fiscal space.
• D. Debt service is fees for issuing debt; it increases fiscal space.

Answer: (A)

Debt service is the cash the government must pay to cover interest and principal on its outstanding debt. This fixed obligation consumes part of the budget, so when debt service is large relative to revenue, there’s less money left for public services, investments, or contingency funds. That curtails fiscal space—the ability to finance priorities, respond to shocks, or pursue new policies without risking debt sustainability. Factors like higher interest rates, a larger debt stock, or debt denominated in a foreign currency (which can become more expensive if the local currency weakens) all raise debt service and tighten fiscal space. The other ideas—profits from debt, taxes on debt interest, or issuance fees—refer to different concepts or one-off costs and do not capture the ongoing, binding payments that define debt service.
