Widening Indonesia’s National Budget Deficit

Fiscal policy represents one of the government’s principal instruments for managing the national economy. A budget deficit—the condition in which government expenditure exceeds revenue—is a strategic choice frequently made, particularly when facing economic pressures, the need for large-scale infrastructure investment, or crises requiring immediate fiscal intervention.

Indonesia, as a developing nation aspiring to achieve advanced-economy status by 2045, faces a complex fiscal dilemma. On one hand, spending requirements for infrastructure, education, healthcare, and social protection are enormous. On the other hand, the state’s revenue capacity remains constrained, with the tax-to-GDP ratio hovering around 10–11%—well below the OECD average of 34%.

The current 3% of GDP deficit ceiling reflects a compromise between spending needs and fiscal prudence. Nevertheless, a wide range of stakeholders—academics, international institutions, and politicians alike—frequently debate whether this threshold remains relevant, and whether a measured widening could accelerate development without sacrificing economic stability.

This essay aims to provide a balanced, evidence-based analysis of the various aspects—both positive and negative—of a policy to widen Indonesia’s budget deficit across several distinct scenarios.

THE LEGAL FRAMEWORK AND INDONESIA’S FISCAL CONTEXT

Legal Constraints on the Budget Deficit

Law No. 17 of 2003 on State Finance establishes a maximum budget deficit of 3% of GDP and caps total government debt at 60% of GDP. These thresholds align with the Maastricht Criteria applied by the European Union, reflecting Indonesia’s commitment to fiscal discipline since the Reform Era (Reformasi).

In extraordinary circumstances, the government has previously granted exceptions. During the COVID-19 pandemic (2020–2022), through Government Regulation in Lieu of Law No. 1 of 2020 (subsequently enacted as Law No. 2 of 2020), the 3% ceiling was suspended and the deficit reached 6.14% of GDP in 2020—the highest in Indonesia’s modern history. The government set a fiscal consolidation target of returning to the 3% threshold by 2023, which was successfully achieved.

MULTI-SCENARIO DEFICIT ANALYSIS

To provide a comprehensive analysis, this essay organises its discussion around four distinct deficit scenarios, each characterised by a different profile of risks and opportunities.

Scenario	Deficit Threshold	Additional Fiscal Space*	Risk Level
Scenario A	3% – 4% of GDP	IDR 150–180 trillion	Moderate
Scenario B	4% – 5% of GDP	IDR 300–350 trillion	Significant
Scenario C	5% – 6% of GDP	IDR 450–500 trillion	High
Scenario D	Above 6% of GDP	> IDR 600 trillion	Very High

 Table 2. Summary of Deficit Scenarios | *Estimated additional fiscal space relative to the 3% of GDP ceiling

Scenario A: Deficit of 3–4% of GDP (Measured Expansion)

Positive Aspects and Advantages

• Provides additional fiscal space of approximately IDR 150–180 trillion per annum, which can be allocated to infrastructure, healthcare, and education spending without compromising other priority programmes.

• The crowding-out effect on the private sector remains relatively limited, as the additional financing requirement can still be absorbed by the market without placing significant upward pressure on interest rates.

• The risk to fiscal reputation remains contained: international credit rating agencies—Fitch, Moody’s, and S&P—would generally maintain Indonesia’s investment-grade status, provided the widening is temporary and accompanied by a credible consolidation plan.

• The resulting economic stimulus could raise GDP growth by 0.2–0.5 percentage points through the fiscal multiplier effect of government spending, particularly in the construction and services sectors.

Negative Aspects and Disadvantages

• Requires an amendment to, or exception from, the State Finance Law—sending a negative signal regarding Indonesia’s long-term fiscal commitment.

• Moderate pressure on the Indonesian rupiah, particularly if the additional deficit financing is reliant on foreign investors who are sensitive to changes in global conditions (risk-off episodes).

• Precedent effect: once the threshold is relaxed, political pressure to continue widening it in the future becomes considerably stronger, creating a risk of entrenched deficit bias that is difficult to control.

Scenario B: Deficit of 4–5% of GDP (Aggressive Expansion)

Positive Aspects and Advantages

• The significant additional fiscal space (IDR 300–350 trillion) could fund large-scale transformation programmes, such as acceleration of industrial downstream processing, the development of the new capital city Nusantara (IKN), and ambitious social programmes—such as a nationwide free nutritious meals scheme—at full scale.

• If directed towards high-multiplier expenditure (productive infrastructure, research and technology, human capital development), this could drive growth towards the 6–7% of GDP range per annum—the rate required to escape the middle-income trap.

• In the context of a global economic slowdown, fiscal expansion at this level could serve as an effective buffer, reducing Indonesia’s dependence on volatile commodity exports.

Negative Aspects and Disadvantages

• A dramatic increase in financing requirements would put upward pressure on Government Securities (SBN) yields. An estimated rise of 50–100 basis points could significantly increase government borrowing costs and worsen debt sustainability dynamics.

• The risk of a credit rating downgrade becomes real. Loss of investment-grade status could trigger a massive capital outflow from the SBN and equity markets, sharply weakening the rupiah and worsening inflation.

• The domestic economy’s absorptive capacity has limits: if government expenditure surges more rapidly than productive capacity, the resulting inflationary pressure will erode the very benefits of the fiscal stimulus.

Scenarios C & D: Deficit of 5–6% and Above 6% of GDP (Extreme Expansion)

Positive Aspects (Limited)

• In a clearly defined emergency—such as a catastrophic natural disaster or a global financial crisis—extreme fiscal expansion may be the only available instrument to prevent economic collapse, as demonstrated during the COVID-19 pandemic in 2020.

• The very substantial spending capacity could, in theory, simultaneously finance the structural transformation of the economy: renewable energy, digitalisation, and industrialisation within a single budgetary period.

 

Negative Aspects and Disadvantages (Dominant)

• Disproportionate fiscal risk: at this level, financing requirements exceed the capacity of the domestic market, compelling the government to rely on foreign-currency-denominated external debt—increasing currency mismatch and the risk of a balance-sheet crisis.

• Strong and persistent inflationary pressure, which could force Bank Indonesia to raise interest rates sharply, thereby suppressing private sector growth momentum.

• Debt spiral: sharply rising interest payments crowd out productive expenditure in future budgets, creating a vicious cycle of fiscal dependency.

• Loss of market and investor confidence: at this deficit level, Indonesia risks a sudden stop in external financing, forcing an abrupt fiscal adjustment far more painful than a planned consolidation.

MACROECONOMIC PERSPECTIVE

Impact on Economic Growth

Keynesian theory holds that government expenditure carries a multiplier effect on the broader economy. However, the magnitude of this multiplier depends heavily on economic conditions, the structure of financing, and the quality of expenditure. Research by Barro (1990) and Blanchard & Leigh (2013) demonstrates that fiscal multipliers in developing economies tend to be larger (1.2–1.5x) when the output gap is negative and interest rates are low.

Indonesia faces an enormous infrastructure investment gap—estimated at USD 1.6 trillion through to 2030. A wider deficit, if channelled into high-quality infrastructure spending, has the potential to generate a return on investment exceeding the cost of debt financing, yielding a net benefit to the economy.

However, these positive effects are only realised if expenditure quality is maintained. Indonesia’s historical experience reveals that low budget absorption rates and fiscal leakage through corruption significantly reduce the effectiveness of fiscal stimulus.

4.2 Inflation Dynamics and Macroeconomic Stability

A significant widening of the deficit can create demand-pull inflationary pressures, particularly if domestic productive capacity cannot absorb the surge in demand. In the context of Indonesia’s continued reliance on imports of capital goods and raw materials, a depreciation of the rupiah triggered by deficit pressures would compound cost-push inflationary forces.

Bank Indonesia would face a policy dilemma: raising interest rates to defend price stability and the exchange rate would suppress economic growth and increase the government’s debt-servicing burden. Conversely, allowing a large fiscal expansion without monetary adjustment risks undermining the credibility of the inflation targeting framework that has been painstakingly built up over many years.

FINANCIAL AND BOND MARKET PERSPECTIVE

Dynamics of the Government Securities (SBN) Market

Indonesia is heavily reliant on the SBN market to finance its budget deficit. Foreign ownership of domestic SBN has historically accounted for 30–40% of total outstanding stock—one of the highest proportions amongst developing economies—making Indonesia highly vulnerable to shifts in global investor sentiment.

A significant increase in the deficit would drive up the supply of SBN. If demand does not grow proportionately, yields will rise, increasing government interest costs and potentially triggering a crowding-out effect on private investment. Estimates suggest that each additional 1% of GDP in deficit could push SBN yields up by 30–60 basis points under normal market conditions.

 

Refinancing Risk and Debt Management

 

Indonesia’s debt maturity profile requires careful management. With an average SBN maturity of approximately 8–9 years, the government must regularly refinance substantial amounts. A higher deficit means a faster accumulation of debt and a larger future refinancing requirement—creating a more significant rollover risk.

Diversification of financing instruments is therefore crucial: green bonds, sukuk, and other innovative instruments can broaden the investor base. However, each new instrument requires time for market development and carries its own pricing premium.

Deficit Scenario	Est. Yield Increase	Impact on Debt Servicing	Foreign Ownership Risk
3–4% of GDP	+30 – 50 bps	Manageable	Moderate
4–5% of GDP	+50 – 100 bps	Significant	High
5–6% of GDP	+100 – 200 bps	Burdensome	Very High
Above 6% of GDP	>200 bps	Unsustainable	Extreme

POLITICAL AND FISCAL POLICY PERSPECTIVE

The Political Economy of the Deficit

Budget deficits carry a political dimension that cannot be disregarded. In general, politicians face asymmetric incentives: the benefits of government spending (particularly social transfers and subsidies) are felt directly by voters, whilst the costs of deficit financing are dispersed into the future and remain indirect. This creates a structural bias towards overspending and chronic fiscal deficits.

In the Indonesian context, the APBN deliberation process is an intensely politicised exercise. A broad governing coalition in the House of Representatives (DPR) facilitates the passage of budgets, but also creates pressure to accommodate the interests of numerous factions—which can inflate expenditure and drive the deficit wider.

6.2 Implications for Bank Indonesia’s Independence

An excessively expansionary fiscal policy can threaten the independence of the central bank. When the deficit balloons and market financing becomes difficult to secure at affordable rates, pressure on Bank Indonesia to purchase government securities directly (debt monetisation) intensifies. This precedent is dangerous: uncontrolled debt monetisation is one of the primary causes of hyperinflation throughout economic history.

 

Governance and Expenditure Quality

The effectiveness of fiscal stimulus from a wider deficit depends critically on the quality of public expenditure governance. Indonesia continues to face serious challenges in this regard, including: low budget absorption capacity at the regional level; corruption that erodes the value of public spending; the rigidity of mandatory spending, which narrows the space for productive expenditure; and significant disparities in planning capacity between central and regional governments.

Without fundamental improvements in governance, a wider deficit will simply enlarge an inefficient budget, rather than accelerating development.

Experiences of Developing Economies

Several developing economies have experienced the consequences of an uncontrolled deficit. Sri Lanka (2022) suffered a fiscal crisis and sovereign default following a combination of chronic fiscal deficits, poorly planned tax cuts, and the pandemic—which drained the country’s foreign exchange reserves. Argentina represents the classic case of a country that has repeatedly experienced crises as a result of fiscal indiscipline.

Conversely, India has managed to sustain a deficit in the range of 5–6% of GDP for several years whilst maintaining robust economic growth, underpinned by a deep domestic market and investor confidence maintained through consistent policy communication.

Country	Avg. Deficit (2019–2023)	Avg. Growth	Credit Rating	Notes
Indonesia	2.9% of GDP	3.4% p.a.	BBB/Baa2	Post-pandemic consolidation
India	6.5% of GDP	5.1% p.a.	BBB-/Baa3	Deep domestic market
Brazil	7.2% of GDP	1.2% p.a.	BB-/Ba2	Recurring fiscal crises
Malaysia	4.1% of GDP	3.8% p.a.	A-/A3	Relatively sound debt management
Sri Lanka	9.8% of GDP	-0.6% p.a.	SD/Ca	Default 2022
Germany	1.1% of GDP	0.8% p.a.	AAA/Aaa	Debt brake policy

Lessons from Europe: The Maastricht Criteria and Their Flexibility

The European Union, which inspired Indonesia’s 3% of GDP ceiling, has itself undergone an evolution in the application of its fiscal rules. Following the European debt crisis of 2010–2012 and the COVID-19 pandemic, the EU introduced greater flexibility through a revised Stability and Growth Pact (SGP) in 2024, allowing member states to establish more realistic fiscal consolidation paths tailored to their individual circumstances.

The key lesson is this: it is not the size of the deficit alone that determines fiscal sustainability, but rather the combination of: the state’s revenue capacity; the quality and productivity of expenditure; the depth and liquidity of domestic financial markets; and the credibility and consistency of fiscal policy over the long term. 

CONCLUSIONS AND RECOMMENDATIONS

Synthesis

Based on the multidimensional analysis conducted, it can be concluded that the question is not merely ‘what is the optimal deficit threshold’, but rather ‘how can Indonesia build the fiscal capacity to support sustainable development.’ Widening the deficit can be an effective instrument if, and only if, it is pursued within an appropriate framework.

 

Policy Recommendations

• Conditional deficit widening: Should a wider deficit be pursued, it must be accompanied by a clear sunset clause, automatic fiscal rules, and measurable allocations strictly limited to high-multiplier expenditure whose benefits can be independently verified.

• Strengthening the domestic capital market: Deepening the SBN market through the development of domestic institutional investors (pension funds, insurance companies) in order to reduce dependence on volatile foreign investors.

• Public expenditure reform: Improving the quality and efficiency of government spending through strengthened procurement systems, performance-based regional transfer mechanisms, and better-targeted subsidy reform.

• Structured fiscal-monetary coordination: Establishing clear coordination mechanisms between the Ministry of Finance and Bank Indonesia to prevent fiscal dominance from threatening monetary stability.

 

Closing Remarks

Widening the budget deficit is a double-edged sword. In the right dosage and context, it can serve as a transformative catalyst for growth. However, without strong institutional foundations, consistent revenue reform, and accountable governance, excessive fiscal expansion will merely transfer the burden from the present generation to future ones—a form of intergenerational inequity that cannot be justified even by the most compelling development rationale.

Indonesia does have room to operate more flexibly in the management of its public finances, but the ability and legitimacy to use that room must be earned through a consistent track record of sound policy—not seized instantaneously through the mere relaxation of a legal threshold.
