Indonesia’s Fiscal Outlook in a Period of Divergent Signals

How to make sense of a number of apparently contradictory outlooks on the country’s economic and fiscal health.

Indonesia is not in a fiscal crisis. Instead, it is facing a different challenge, one that is harder to interpret and potentially more important: a divergence in perception.

At a time when parts of the international market are beginning to question Indonesia’s fiscal trajectory, others continue to describe it as one of the more resilient and stable economies in the emerging market universe. More than a marginal disagreement, this represents a fundamental divide in how Indonesia is being assessed.

For investors, this creates a familiar but uncomfortable dynamic. When the signals diverge, confidence weakens, not necessarily because the fundamentals have deteriorated, but because the narrative around them has fractured.

The question, therefore, is not simply whether Indonesia’s fiscal position is strong or weak. It is whether the growing divergence in external views reflects a real underlying risk or different ways of assessing an economy in transition. To answer that, one must first return to the fundamentals.

At a headline level, those fundamentals remain relatively stable. Public debt is still moderate at roughly 40 percent of GDP, the fiscal deficit is limited by a statutory ceiling of 3 percent, and tax revenues, while structurally low at around 10 percent of GDP, continue to provide the core funding base. These constraints define both the resilience of the system and the limits within which policy must operate.

From February to April of this year, several distinct assessments of Indonesia’s fiscal health have emerged.

The first of these assessments is cautionary. Both Moody’s Investors Service and Fitch Ratings have revised Indonesia’s outlook from stable to negative. This signals that while Indonesia remains investment grade, the margin for error is narrowing. The concern is whether the country’s current policy direction can be executed without placing pressure on its credit profile. These agencies are therefore focused on how their policy trajectory may shape their credit profile going forward.

The second assessment is more positive. S&P Global Ratings has maintained a stable outlook, reflecting confidence that Indonesia’s long-standing fiscal discipline and macroeconomic management remain intact. In effect, this suggests that, in S&P’s view, the current policy trajectory remains broadly consistent with maintaining credit stability.

The third is more negative, and arguably the most impactful. In late January, the investment research firm MSCI stated that Indonesia’s market is concentrated in a few large, tightly held companies, with limited free float, making it less liquid and harder to price. This has effectively limited a key channel of capital inflows through index eligibility and weighting constraints linked to market accessibility, pending improvements in Indonesia’s trading conditions. In a market structurally reliant on portfolio flows, even marginal changes in index accessibility can have disproportionate effects on capital allocation and the cost of funding.

Set against these external assessments is a more constructive view from the multilaterals, the International Monetary Fund (IMF) and the World Bank. Both continue to describe Indonesia as a relative outperformer, projecting steady growth, manageable inflation, and adherence to fiscal rules that many peers have struggled to maintain. Recent engagements with the IMF in Washington have reinforced this view, with Indonesian policymakers emphasizing that existing fiscal and external buffers remain sufficient.

These various assessments reflect the different mandates of those making them, rather than a direct contradiction. The rating agencies are asking a downside question: What happens if execution falters? The multilaterals are asking a structural question: What happens if reforms succeed?

From Divergence to Drivers

The divergence results from the fact that Indonesia is being evaluated through both lenses at the same time. As a result, much of the discussion around Indonesia’s fiscal outlook becomes unnecessarily complicated. In reality, the fiscal drivers are concentrated in a few key areas.

On the revenue side, taxation – primarily income tax and VAT – provides the bulk of revenue, with non-tax revenues from natural resources acting as a key swing factor, and the new state investment fund Danantara playing an increasingly important role. The upshot of this is that Indonesia’s fiscal strength ultimately rests on its ability to expand and stabilize its tax base.

On the expenditure side, a large portion of spending is effectively fixed. Transfers to regions, interest payments, and personnel costs consume a significant share of the budget before policy choices are even made. Within this, rising global interest rates and exchange rate movements increase sensitivity in borrowing and refinancing costs, particularly given Indonesia’s reliance on foreign investor participation in its local currency bond market.

What remains is driven by a relatively concentrated set of variables – principally tax revenue performance on one side, and energy and social spending on the other – which together shape a large share of fiscal outcomes, while remaining materially exposed to commodity price cycles and financing conditions.

The government is not without a plan. In fact, the current reform agenda is among the most ambitious in recent decades.

The rollout of the CoreTax system is central to this effort. By integrating data, automating reporting, and reducing the scope for non-compliance, it is designed to fundamentally reshape tax administration. If successful, it aims to lift Indonesia’s structurally low tax-to-GDP ratio from around 10 percent to as high as 16 percent, which is more consistent with regional peers. This will not be an immediate fix. The system is still in its early stages of development, and while initial results are encouraging, it will take time before it translates into sustained revenue expansion.

Albeit less in effect, a similar revenue dynamic exists in the energy and state-owned sectors. Indonesia is sitting on a pipeline of large-scale gas developments, which include ENI’s East Kalimantan Kutei projects, Mubadala’s South Andaman project, Inpex’s Masela project and British Petroleum’s Tangguh Ubadari/CCUS project that could materially reshape its fiscal and external position. The question here is about timing. These projects are capital-intensive and multi-year in nature, and are unlikely to bring short-term relief.

Danantara represents an even more fundamental shift. By consolidating state-owned enterprises into a single investment platform, the government is attempting to move from a budget-constrained growth model toward one driven by asset........
