Cap the Debt Service Share of Revenue Before It Crowds Out the Budget

Diagnosis

The problem is the combined external and domestic debt service share of revenue, and it is rising. This is a medium-horizon, macro-financial pressure that compounds quietly. When debt service (interest plus principal on both external and domestic borrowing) absorbs a growing slice of government revenue, every taka committed to creditors is a taka unavailable for health, education, and capital spending. The current_state value is not yet populated in the registry (the indicator collector exists but the level is null), so the immediate task is twofold: establish the measured ratio with a defensible methodology, and put a governing ceiling around it before the trend hardens.

The danger is that debt service is the most senior, least discretionary line in the budget. Unlike a development project that can be paused, coupon and amortization payments fall due on a fixed calendar. A rising share means that revenue growth is being pre-committed to past borrowing rather than funding present priorities. Domestic debt service is especially corrosive when it is short-dated and high-coupon, because it must be refinanced frequently at whatever rate the market demands.

Recommended actions

1. Publish the measured ratio and set a ceiling. Owner: Ministry of Finance (MoF). Mechanism: a debt service to revenue indicator published quarterly in the Debt Management Wing reports, plus a medium-term ceiling written into the Medium Term Macroeconomic Policy Statement that accompanies the budget. Observable signal: the ratio is reported on a fixed schedule and the published number falls within the stated ceiling band.
2. Lengthen domestic maturities to cut rollover pressure. Owner: MoF Treasury and Debt Management Wing, supported by Bangladesh Bank as issuance agent. Mechanism: shift the Treasury auction calendar toward longer-tenor bonds and away from short bills, and use Bangladesh Securities and Exchange Commission rules to deepen secondary-market trading so longer bonds clear. Observable signal: weighted average maturity of outstanding domestic debt rises and the share rolled over each quarter falls.
3. Raise the revenue denominator. Owner: Internal Resources Division (IRD) through the National Board of Revenue. Mechanism: broaden the tax base via VAT compliance enforcement and reduced exemptions, codified in the annual Finance Act. Observable signal: revenue grows faster than debt service, so the ratio declines even as nominal service rises.
4. Prioritize concessional over commercial external borrowing. Owner: MoF Economic Relations Division with the General Economics Division (GED). Mechanism: a borrowing policy in the next national plan that ranks financing by grant element and caps new non-concessional commitments. Observable signal: the average interest cost of new external loans falls and the concessional share of the pipeline rises.
5. Build an early-warning trigger. Owner: MoF with Bangladesh Bank. Mechanism: a standing rule that any quarter breaching the ceiling triggers a written corrective plan to the Cabinet. Observable signal: triggers fire and corrective plans are tabled, rather than the ceiling being silently exceeded.

Sequencing (first 12 months)

First, MoF must produce and publish the debt service to revenue number with a documented methodology. Without an agreed measure, no ceiling, trigger, or maturity target can be enforced. Once the baseline exists, MoF sets the medium-term ceiling in the budget statement, which unlocks the early-warning trigger. In parallel, Bangladesh Bank and MoF begin tilting the auction calendar toward longer tenors, because maturity extension takes several quarters to move the average. IRD revenue measures start in the same budget cycle so the denominator begins improving alongside the supply-side fixes.

Risks and constraints

The binding constraint is fiscal: lengthening maturities and favoring concessional loans can raise upfront coupon costs or slow disbursement, and revenue reform meets resistance from exemption beneficiaries. Politically, a published ceiling exposes the government to scrutiny when it is breached, which creates pressure to weaken the methodology rather than the spending. Domestic market depth is itself a constraint: longer bonds only help if investors will hold them, so SEC-led market development is a precondition, not an afterthought.

Bottom line

Debt service rising as a share of revenue is a slow squeeze that pre-commits future budgets to past borrowing, and the first defense is to measure it honestly and cap it publicly. MoF should publish the ratio, set a ceiling, lengthen maturities, and lift revenue so interest never quietly crowds out the rest of the budget.
