Indonesia’s fiscal performance in 2023 showed a significant improvement on the headline balance, with the government posting a primary surplus of Rp102.6 trillion—contrasting with a primary deficit of Rp74.1 trillion in 2022—according to figures compiled in official debt-table material referenced by the Ministry of Finance. The primary surplus, which reflects the government’s ability to cover primary spending (spending excluding interest costs) from revenues, provides an early signal of fiscal discipline even as overall borrowing needs remain a central feature of public finance management.
Despite the primary surplus, 2023 ended with an overall deficit of Rp337.3 trillion. That shortfall corresponded to 1.61% of GDP, underscoring that while the government’s core balance improved, it still faced substantial spending pressures and financing requirements. In other words, the year’s results suggest that the deficit was not driven by the primary portion of the budget alone; rather, it continued to reflect the broader structure of government outlays and obligations, including those beyond the primary line.
Attention has increasingly turned to how Indonesia balances deficit outcomes with debt sustainability. The same official debt-table material notes that as of March 31, 2024, the central government’s debt-to-GDP ratio stood at 38.8%. This indicator is closely watched by investors and policymakers because it links the size of public liabilities to the economy’s capacity to service them through growth and revenues.
In dollar terms, the document places the central government’s total public debt at U.S.$520.5 billion as of the March 31, 2024 reference point. It further breaks down the composition of that debt by instrument type: 11.9% is reported as loans, while 88.1% is in bonds. That split is significant for market dynamics, since bond-heavy structures tend to be influenced by domestic and international interest-rate conditions and investor appetite, while loan components are typically more tied to negotiated terms and creditor relationships.
Credit-risk analysts and financial institutions have also emphasized the importance of external-debt structure when assessing vulnerability. A Bank Indonesia presentation on external debt notes that Indonesia’s external debt profile remains manageable, with the external debt structure dominated by long-term debt. It also highlights that external debt to GDP and debt-to-export ratios are key gauges used to contextualize leverage against economic and trade capacity, and it frames the overall composition as something that policy can support rather than a looming stress point.
In that external-debt overview, the presentation describes how foreign-currency bonds and various government securities contribute to the broader picture. The material indicates that foreign loan and foreign-currency bond segments play major roles, alongside domestic loan and domestic bonds. Such composition matters because currency mismatch and maturity profiles can raise or reduce rollover risk; by showing a long-term dominant structure, the presentation’s framing suggests fewer immediate refinancing shocks relative to a short-dated portfolio.
The same Bank Indonesia package also provides detail on government debt securities issuance and recent market developments. It states that by November 30, the realized issuances for Government Debt Securities (SUN) totaled Rp866.77 trillion, including Rp734.42 trillion denominated in rupiah and Rp132.35 trillion denominated in foreign currency. For Sovereign Sharia Securities (SBSN), realizations reached Rp395.55 trillion, made up of Rp315.24 trillion rupiah-denominated and Rp80.31 trillion foreign-currency-denominated. These figures illuminate the government’s continued reliance on both domestic and foreign-currency instruments, reflecting the practical need to fund deficits while distributing financing sources across markets.
Market participation trends provide another window into how Indonesia’s debt is being absorbed. The Bank Indonesia presentation reports that total securities issuance reached Rp259.24 trillion year-to-date in 2024, and Rp238.67 trillion as of November 2025. In November 2025, non-residents recorded a net sell of Rp5.93 trillion in government bonds, while simultaneously posting a net buy of Rp12.20 trillion in equities. It also notes that the number of investors in the capital markets reached 19.67 million by the end of November 2025, up 34.86% year-on-year, suggesting deepening domestic participation that can support liquidity and market resilience.
Interest costs—often a decisive factor for future fiscal space—remain under scrutiny. Data compiled from the Ministry of Finance, as summarized by Katadata’s Databoks, indicates that interest payments on Indonesia’s government debt have continued to increase over the period observed from 2015 to 2024. While the exact yearly path is not reproduced in the brief excerpt, the direction of travel is clear: rising interest payments can gradually offset improvements in the primary balance, especially if benchmark rates remain elevated or if portions of debt are repriced under prevailing market conditions.
Taken together, Indonesia’s 2023 primary surplus alongside an overall deficit, and the subsequent debt benchmarks, shape the current fiscal narrative. The government’s ability to generate a primary surplus suggests improved underlying budgeting discipline; the 2023 overall deficit indicates that obligations still require financing; and the March 31, 2024 debt-to-GDP ratio provides a measurable point-in-time gauge of sustainability. Meanwhile, the external debt framing from Bank Indonesia emphasizes that the external profile is not only about totals, but also about structure—particularly the dominance of long-term components—and thus helps contextualize how debt risks may evolve.
For policymakers, the challenge is to preserve the gains in the primary balance while preventing interest cost pressures from eroding future fiscal space. For investors, the key question is whether debt dynamics remain stable as issuance continues across SUN and SBSN, and as the market’s currency and maturity mix interacts with global rates. With the debt composition heavily weighted toward bonds and external structure characterized as manageable, the direction of travel will likely depend on the interaction among economic growth, deficit financing needs, and the cost of servicing an increasingly market-influenced public debt portfolio.
