Indonesia’s public debt dynamics have entered the spotlight as the Indonesia debt to GDP fiscal risk ratio reached approximately 40.08 percent in 2025, prompting renewed attention from global credit rating agencies such as Moody’s and Standard & Poor’s (S&P). This rise in debt burden has ignited debate over fiscal sustainability, risk management, and long-term economic resilience, even as the nation posts respectable growth figures relative to peers. According to recent reports, Indonesia’s debt-to-GDP ratio near 40 percent is significantly higher than previous years, attracting scrutiny from institutional investors and policymakers alike.

In this article, we will unpack what this ratio means for Indonesia’s fiscal health, why credit rating agencies are watching closely, and how economic policymakers and markets are responding to these developments. We will also provide context by comparing Indonesia’s situation to regional and global peers.

Understanding the Rising Debt-to-GDP Ratio

The debt-to-GDP ratio is a key metric used by economists and international institutions to assess the sustainability of a country’s public finances. It measures the total government debt relative to the country’s economic output, gauging how capable a nation is of servicing and repaying its obligations. For Indonesia, the debt ratio hitting 40.08 percent in 2025 reflects both the cumulative impact of pandemic-era fiscal measures and recent policy choices aimed at stimulating growth and financing social programs.

Historically, Indonesia maintained relatively conservative debt levels compared with many emerging markets. As of June 2025, total government debt reached roughly Rp9,138.05 trillion, equivalent to around 39.86 percent of GDP, up modestly from previous years. This increase occurred as spending on social assistance, infrastructure development, and fiscal stimulus programs continued, especially in response to global economic uncertainties and domestic priorities.

From a global perspective, Indonesia’s debt ratio remains well below the thresholds signaled by some fiscal rules and comparisons to peers. For instance, the Maastricht criteria for European Union members set a reference debt limit of 60 percent of GDP. Many countries in Southeast Asia and beyond run significantly higher ratios; Malaysia and the Philippines have ratios above 60 percent, while India’s exceeds 80 percent. In that context, Indonesia’s near-40 percent level does not immediately signal crisis conditions.

However, credit rating agencies are not focused on the absolute number alone. They also examine trends, governance practices, fiscal policy credibility, revenue generation capacity, and how quickly the ratio might climb without corrective action. This broader assessment is crucial to understanding why agencies like Moody’s and S&P are signaling caution.

Credit Rating Agency Concerns and Fiscal Risk Warnings

Credit rating agencies play a central role in global financial markets by assessing sovereign creditworthiness, influencing investor perceptions and capital flows. Recently Moody’s downgraded Indonesia’s credit rating outlook from stable to negative, underscoring concerns around policymaking predictability, fiscal trajectory, and governance quality. The agency, while maintaining the Baa2 investment-grade rating, flagged that an expansionary fiscal stance without accompanying revenue reforms could exacerbate risks.

Moody’s warning arrived amidst market turbulence triggered by transparency concerns flagged by MSCI, leading to a sharp sell-off in Indonesian financial assets. Market indices like the Jakarta Composite Index fell, and the rupiah weakened, reflecting investor nervousness about potential fiscal instability and policy inconsistency.

Standard & Poor’s (S&P), which affirmed Indonesia’s BBB/A-2 rating with a stable outlook in 2025, also assesses fiscal dynamics closely. Its reports highlight that Indonesia’s resilient growth prospects and relatively light net external debt help underpin the rating. Nonetheless, S&P has noted the possibility of revision if debt consistently rises or if government interest payments outpace revenue growth.

The concerns raised by ratings agencies are not merely technical. They influence borrowing costs for sovereign debt and can impact investor confidence. If investor risk perceptions deteriorate, yields on government bonds can rise, increasing debt servicing costs and narrowing fiscal space for other priorities.

Fiscal Policy Choices and Deficit Management

One of the reasons behind the uptick in the debt ratio is fiscal policy choices that consciously leaned toward counter-cyclical spending and social support measures. The Indonesian government’s decision to widen the budget deficit closer to the technical ceiling of 3 percent of GDP reflects efforts to spur growth during periods of slower external demand. For example, the 2025 state budget deficit stood at 2.92 percent of GDP, while the 2026 budget targeted a 2.68 percent deficit.

While these figures remain within legal bounds, persistent reliance on deficit financing without robust revenue mobilization can sustain upward pressure on debt. This dynamic is crucial in the view of fiscal risk because a weak revenue base limits flexibility. Tax revenues in Indonesia have historically lagged behind those of many middle-income peers, leading to debates about tax reform and broadening the tax base as necessary steps for long-term sustainability.

Moody’s specific criticism of "reduced predictability in policymaking" stems from concerns about transparency and the consistency of fiscal governance frameworks. Policy shifts with political undercurrents—such as controversial appointments or ambitious spending programs—can unsettle international investors and raise the perceived risk of future fiscal loosening.

Economic Growth, Debt Servicing, and Structural Dynamics

Despite fiscal concerns, Indonesia’s economy has shown resilience. Official data reported that GDP grew at 5.11 percent in 2025, the fastest pace in three years, driven by household consumption and investment. This pace, while below the government’s ambitious 8 percent target, signals ongoing economic momentum in a challenging global environment.

A growing economy can mitigate debt risks by expanding the nominal GDP, effectively reducing the debt ratio even if debt levels rise in absolute terms. Debt sustainability analyses often consider this interplay: a robust growth trajectory helps absorb fiscal obligations more comfortably. However, structural factors such as tax revenue performance, reliance on commodity exports, and external demand conditions still influence the broader risk picture.

The International Monetary Fund (IMF) emphasizes that maintaining credible fiscal rules, enhancing revenue mobilization, and managing quasi-fiscal activities are essential for sustainable growth. IMF consultations have leaned on the importance of preserving policy credibility and fiscal buffers amidst external uncertainties.

While Indonesia’s public debt ratio remains moderate by global standards, the trajectory of its fiscal variables matters. If deficits widen systematically without commensurate revenue improvements, the debt ratio may rise further, inviting more scrutiny from global investors and credit agencies.

Comparisons With Regional and Global Peers

Making sense of the Indonesia debt to GDP fiscal risk requires comparing the country’s metrics with regional and global peers. As noted, several ASEAN countries maintain higher debt ratios, yet different structural characteristics—such as export diversification, foreign exchange reserves, and socioeconomic resilience—affect how risk is evaluated.

For example, neighboring Malaysia and the Philippines carry debt ratios above 60 percent of GDP, but their fiscal frameworks and macroeconomic backstops differ from Indonesia’s. Meanwhile, India’s ratio is well above 80 percent, reflecting both historical spending patterns and policy responses to macroeconomic shocks.

Debt composition matters too. Indonesia’s debt mix contains a significant share denominated in domestic currency, which reduces exposure to exchange rate volatility and external refinancing risk. Still, foreign debt and external obligations warrant monitoring, especially when global financial conditions tighten.

Credit rating agencies and investors weigh these structural differences when assessing sovereign risk. Stronger institutional frameworks, disciplined fiscal rules, and transparent governance can signal resilience even with elevated debt ratios.

Policy Responses and Future Directions

In response to fiscal risk concerns, Indonesian authorities have reiterated commitments to prudent debt management, governance reforms, and fiscal discipline. The Finance Ministry and central bank emphasize that Indonesia’s fundamentals—such as moderate debt levels, stable inflation, and resilient growth—provide buffers against abrupt fiscal stress.

There are ongoing discussions about improving tax administration, broadening tax bases, and instituting medium-term expenditure frameworks to better align spending with revenue capacities. Strengthening public financial management and transparency can bolster investor confidence and mitigate the impact of risk warnings from international agencies.

At the same time, maintaining social spending and investment in infrastructure remains crucial for inclusive growth. Balancing these priorities while preserving fiscal sustainability is a significant policy challenge that will shape Indonesia’s economic trajectory in the coming years.
