Indonesia to Revise State Finance Law But Deficit Ceiling Will Stay, Lawmaker Says
Indonesia’s parliament will soon begin deliberating on a revision to state finance laws, but the focus will not be on changing rules on fiscal deficit limits, a senior lawmaker said on Monday, May 25. The announcement came as investors have trained close attention on Southeast Asia’s largest economy’s fiscal path, amid widening deficits, a weakening rupiah, and back-to-back sovereign rating outlook downgrades.

The reassurance is direct, but the pressure behind it is not.
What the Lawmaker Said
Mukhamad Misbakhun, chairman of Indonesia’s House of Representatives Commission XI — the parliamentary body overseeing financial affairs — delivered the signal on Monday.

Misbakhun has been the parliament’s most prominent voice on fiscal stability throughout 2026. In March, as the Jakarta Composite Index fell sharply and rumours circulated about Finance Minister Sri Mulyani Indrawati’s possible resignation, Misbakhun told investors directly that the market decline was a matter of sentiment. “We’ve been through this before, and the market always rebounds. There’s no need for excessive concern,” he said at the time, adding that Indonesia’s fiscal policy remained on a strong and sustainable path. OilPrice.com
Monday’s statement on the state finance law revision follows that pattern: a parliamentary signal designed to cap investor anxiety before formal deliberations begin.
What Is Under Revision
The State Finance Law, passed in the wake of the 1998 Asian financial crisis, caps the budget deficit at 3% of gross domestic product and overall debt at 60% of GDP — long-standing markers of fiscal discipline closely tracked by investors. New Arab
Indonesian lawmakers added a review of the law to their 2026 legislative priorities in September 2025, as President Prabowo Subianto pushed to accelerate growth in Southeast Asia’s largest economy. The inclusion of the law on the legislative agenda had already unsettled markets, with investors interpreting it as a possible precursor to lifting the deficit ceiling that Indonesia has maintained, with one pandemic-era suspension, since 2003. deccanherald
Monday’s announcement confirms the revision will proceed — but Misbakhun’s framing is that the deficit ceiling itself is not what the revision is for.
The Fiscal Pressure Behind the Story
The context behind Monday’s reassurance is a budget under significant strain. Indonesia’s state budget deficit reached IDR 695.1 trillion in 2025, equivalent to 2.92% of GDP — the closest it has come to breaching the 3% cap in years outside the pandemic period. The 2026 budget was approved in September 2025 with a deficit target of 2.68% of GDP, but that was before oil prices surged following the outbreak of the Iran war in late February. MSN
The government has begun to anticipate a potential widening of the 2026 budget deficit that could surpass the 3% of GDP threshold, driven by rising global oil prices and pressure on the rupiah. Coordinating Minister for Economic Affairs Airlangga Hartarto stated in March that several simulations indicate increasing difficulty in maintaining the fiscal deficit below the threshold. “Maintaining the deficit below 3% of GDP is difficult unless we cut spending and reduce growth,” Airlangga said at a cabinet meeting on March 13.

The government has said it is preparing various scenarios, including the option of issuing a Government Regulation in Lieu of Law, known as a Perppu, to provide legal cover if the deficit exceeds 3%. A Perppu is an emergency presidential decree that carries the force of law before parliamentary ratification — the same mechanism used during the COVID-19 pandemic when the ceiling was suspended.

Currency and Credit Rating Pressure
The fiscal debate has coincided with intense pressure on the rupiah. The rupiah briefly weakened to 17,400 per US dollar in May 2026, its lowest level on record, raising the cost of rolling over debt sharply. The government has been forced to offer elevated yields to attract investors, including global bond issuances offering yields as high as 5.5% for long tenors. Substack
Earlier in May, Misbakhun himself challenged Bank Indonesia Governor Perry Warjiyo directly to strengthen the currency, telling him the rupiah must return to around IDR 16,000 per US dollar by mid-year so that the full-year average reaches the 2026 budget assumption of IDR 16,500 per US dollar. “The rupiah must be around a flat IDR 16,000, so that the average reaches IDR 16,500, because it is now above IDR 17,000,” Misbakhun told Perry at a parliamentary hearing on May 18.

On the ratings front, both Moody’s and Fitch Ratings revised Indonesia’s sovereign debt outlook from stable to negative in early 2026. Indonesia’s sovereign credit rating remains at the Baa2/BBB investment-grade level, but the outlook revision signals that the predictability of its policies is being questioned by international capital markets.

A survey of 85 economists conducted by LPEM UI as part of its First Semester 2026 Economist Survey found a consensus trend of negative perceptions of Indonesia’s fiscal trajectory that had not reversed over the survey period. Fortune
What Investors Are Watching
Citigroup’s analysis has explicitly framed a constitutional revision of the 3% deficit cap as its base case, assuming the government will revise the State Finance Law before the second half of 2026. The bank’s analysis described the market’s current calm as built on the assumption that the fiscal breach would be resolved through a legal revision rather than an outright violation. business-standard
The government has set a total net bond issuance target of 799.5 trillion rupiah in 2026, including a planned US-dollar bond sale described as the first by an Asian sovereign this year, as it works to finance an expansionary budget. business-standard
If parliament revises the law without touching the 3% cap, Indonesia faces a different problem: what happens if the deficit breaches it anyway. Citigroup forecast that Indonesia’s debt-to-GDP ratio will rise to about 42% by 2029, up from an estimated 39% in 2025, as expansionary fiscal policy continues. business-standard
Background
Indonesia’s State Finance Law was enacted after the 1998 Asian financial crisis as a fiscal anchor, capping the annual budget deficit at 3% of GDP and total government debt at 60% of GDP. The ceiling was suspended between 2020 and 2022 under a pandemic-era Perppu to allow for emergency health and economic spending. Indonesia’s parliament approved the 2026 budget in September 2025 with a deficit target of 2.68% of GDP, spending of IDR 3,842.7 trillion ($231.5 billion), and an economic growth assumption of 5.4%. Indonesia posted GDP growth of 5.1% in 2025, slightly above the previous year, with the fourth quarter expanding at 5.4% year on year. President Prabowo Subianto, who took office in October 2024, has pursued an expansionary spending agenda, including a major free school meals programme, that has widened the budget gap. New Arab + 2
What Happens Next
Parliament will begin deliberating on the state finance law revision soon, Reuters reported, though no start date was given. The government’s contingency plan — issuing a Perppu if the 2026 deficit exceeds 3% — remains on the table, according to Coordinating Minister Airlangga. Both Moody’s and Fitch are monitoring Indonesia’s fiscal trajectory, and any further deterioration in the deficit path could prompt a formal downgrade from the current Baa2/BBB rating level. Finance Minister Sri Mulyani Indrawati has not publicly indicated whether she supports revising the law or issuing a Perppu if the ceiling is breached, and no parliamentary timeline for completing the revision has been announced.
