Appointment Purbaya was sworn in as the new
Minister of Finance replacing
Sri Mulyani on 8 September 2025. The announcement was made by
Minister of the State Secretariat Prasetyo Hadi. Purbaya said that he was surprised with the sudden appointment and for a brief moment he thought he was being ‘pranked’. His appointment was praised by former president
Joko Widodo, who knows him personally and said that Purbaya came from a different school of economic thought from Sri Mulyani. Right after his appointment, Purbaya made a statement about the
17+8 Demands which generated controversy. Hidayat states that his statement is a dangerous signal to market stability and oversimplifying a complex problem. His statement on the protests was even condemned by the public and
University of Indonesia Student Executive Board demanded for his removal from office. In an economic perspective,
IDX Composite dropped by 1,28% when Purbaya was announced to be the minister replacing Sri Mulyani amidst of
riots and other major cabinet reshuffles. Analysts projected that market participants would adopt a
wait-and-see attitude toward the policies Purbaya would implement. Uncertainty resulting from the change in officials and the controversial statements had the potential to cause a short-term weakening of the Composite Stock Price Index (IHSG). Purbaya reacted to the sudden drop, stating he has been in the financial industry for more than 15 years and the drop is caused by an economic slowdown. He then promised to fix the economy. In his plenary meeting, Purbaya opened his remarks by comparing the meeting atmosphere to the previous meetings as the Head of the
Indonesia Deposit Insurance Corporation (LPS) where he was able to talk "like a cowboy" compared to being a Finance Minister as he had to refine his way to explain to the member's laughter. One member quipped that he may be a cowboy as long as he's able to get things done. Purbaya handled questions and criticism from members regarding on the state budget and his overconfidence of reaching a 6-7% GDP growth, even regarding to non-taxation revenue, only to then rebuke members that "You have meetings with the finance minister (Mulyani) for few hundred days in a year, why haven't you asked that? And when I came here, all the sudden, wow, everything became very long". Purbaya then announced in the meeting that he will stimulate the economy by redistributing IDR 200 trillion from
Bank Indonesia to banks under Prabowo's approval. He then announced on 12 September that five state owned banks will receive the funding, which are
Bank Mandiri,
Bank Negara Indonesia,
Bank Rakyat Indonesia,
Bank Tabungan Negara and
Bank Syariah Indonesia. As a result, the
IDX Composite reacted positively as stock prices went up driven by stock rallies from the finance sectors. Despite this, his policy was criticized by
Darmadi Durianto who warned that
inflation would rise and devaluate the
Rupiah if the liquidity was not quickly absorbed. On 19 September, Purbaya conducted a surprise inspection by calling the customer service of
Directorate General of Taxes regarding on the implementation of CoreTax tax reporting system. Disguising himself as an ordinary taxpayer and pretending to not knowing about the system itself, Purbaya felt cheated by the call and felt that the staff lied about the system's implementation just to satisfy him. Purbaya also admitted that he only receive the reports of the implementation and intends to oversee the implementation of the system itself while telling his staff to avoid the working culture of
Asal Bapak Senang (Indonesian: As long as you're happy) in bureaucracy. On 2 October 2025, Purbaya announced that he will cut transfer funds to local governments on 2026 because of alleged funds misallocation and mismanagement. As he was discussing the state budget together with the House of Representatives, Purbaya announce that he will cut the transfer to IDR 650 trillion which was later revised to IDR 693 trillion and states that even if the transfer was decreased, the presence of government policies will increase. However
Governor of Jakarta Pramono Anung states that he didn't mind the transfer to his province was cut while Purbaya joked that allocations to Jakarta could be cut even further. Purbaya responded to the 18 governors by asking them to optimize spending to ensure that the transfer of funds from the central government can bring real impact towards the prosperity and development of their respective region. Purbaya also threatened to pull funding from the free nutritious meal program if he found the funds are not optimally used through an evaluation conducted until the end of October 2025. He states that the unused funds will be reallocated to other programs. This however got condemned by his mentor,
Luhut Binsar Pandjaitan who claimed that funds used for the free nutritious meal program were steadily absorbed, but Purbaya states that he will still pull out the funds based on the evaluation. The primary catalyst for the Purbaya Effect was his inaugural policy to relocate IDR 200 trillion from the Surplus Budget Balance (SAL) fund from Bank Indonesia to state-owned banks. The initial manifestation of this effect was seen in mixed market reactions. On Purbaya's first day in office, the Composite Stock Price Index (IHSG) closed 1.78% weaker, which analysts attributed to investor uncertainty. Conversely, the Rupiah exchange rate showed relative stability during the same period. This policy triggered differing analyses among economists. Some parties viewed it as a positive stimulus that could lower lending rates and mobilize the real sector. Meanwhile, other parties voiced caution, arguing that the main issue might not be a lack of liquidity, but rather weak credit demand. Risks such as potential inflation and
moral hazard in the banking sector were also highlighted points. == Economic philosophy ==
