(Bloomberg) — For months, President Prabowo Subianto’s moves to chip away at Indonesia’s long-established economic guardrails have stoked anxiety in markets. This week’s sudden rout suggests investor patience is wearing thin.

The ex-general has been causing unease with his populist spending measures, plans to dilute the central bank’s independence and aggressive policies against foreign businesses like Apple Inc. He fast-tracked laws to expand the role of the military too, triggering angry student protests in Jakarta.

The tipping point came on Tuesday, when rumors that Finance Minister Sri Mulyani Indrawati, who has kept a tight rein on spending during her cumulative 14 years in office, would resign. The stock market dropped the most in three years on the day, prompting government officials and Indrawati herself to come out, one by one, to dispel the speculation. Bank Indonesia was forced to step in to protect the rupiah, Asia’s worst performing currency this year.

The rumors have “renewed fears of reformists being purged and was a catalyst for exposing all the economic problems the country is facing,” said John Foo, founder of Valverde Investment Partners Pte.

While there’s been some reprieve in the markets since then, investors remain rattled by Prabowo’s policy moves, coming at a time when Southeast Asia’s biggest economy is also grappling with US President Donald Trump’s tariff threats and waning demand from China for raw materials.

Top of mind for investors is the fiscal outlook. Once cited by Morgan Stanley as one of the “Fragile Five” markets prone to wild swings in foreign sentiment, Indonesia has steadily improved its credibility to investors thanks to prudent economic management that’s lifted its credit rating out of junk status.

Prabowo, 73, is now threatening to upend that trajectory. His policy steps since taking office in October could push the budget deficit closer to its legal limit of 3% of gross domestic product. He increased his cabinet to more than 100 from around 60 under his predecessor Joko Widodo. After a public outcry, he backtracked on hiking the value-added tax rate, a move which would’ve boosted government revenue.

He implemented a free lunch program for students — a signature campaign pledge — that will cost $30 billion a year, the equivalent of 14% of Indonesia’s entire 2024 budget. To pay for that, he slashed spending in other areas, like infrastructure projects and travel.
