JAKARTA, Jan 20 (Reuters) - Indonesia's rupiah hit an all-time low against the U.S. dollar on Tuesday, even as the dollar index slid, amid renewed worries about central bank independence after the president
picked his nephew among nominees for a senior central bank job.
The rupiah has fallen nearly 2% against the dollar in January, placing it among the worst performing emerging Asian currencies, after dropping 3.5% in 2025. Tuesday's intraday trading low of 16,985 to the dollar was a record.
WHY HAS THE RUPIAH BEEN WEAKENING?
Historically the currency has been sensitive to global market sentiment, but domestic factors have also been at play over the past year.
Data this month showed President Prabowo Subianto booked a 2025 budget deficit of 2.92% of GDP, the widest in two decades except for the COVID-19 pandemic.
That renewed worries about fiscal sustainability in Southeast Asia's largest economy and triggered capital outflows in the bond market.
The nomination of Prabowo's nephew Thomas Djiwandono as a member of Bank Indonesia's board has also reignited concerns about potential erosion of the central bank's autonomy.
The 10-year bond yield hit 6.33% on Tuesday, its highest in more than months.
Rising dollar demand for imports ahead of the fasting month of Ramadan, which starts in the third week of February, added to the recent weakness, some analysts said.
WHY IS THE BUDGET DEFICIT A CONCERN?
Indonesia's 2025 budget deficit is low compared to many countries, but its laws limit the annual deficit and public debt at 3% and 60% of GDP, respectively.
These limits have underpinned investor confidence since the late 1990s Asian financial crisis.
Since before Prabowo took office in October 2024, there has been speculation among investors and analysts about whether he will change the rules to make room for his costly welfare programmes, such as the $20-billion free meals programme and higher defence spending.
Last year, foreign investors net sold roughly $6.4 billion worth of Indonesian government bonds, with the biggest selloff in September, when Prabowo abruptly removed the country's long-time finance minister Sri Mulyani Indrawati.
The fiscal conservative was replaced by growth-focused economist Purbaya Yudhi Sadewa.
WHAT ARE THE CENTRAL BANK INDEPENDENCE CONCERNS?
Concerns about central bank independence also grew in September after BI said it would help fund some of Prabowo's programmes, such as affordable housing, under a so-called "burden sharing" deal with the finance ministry.
Parliament is also deliberating on a bill with provisions to strengthen BI's role in supporting economic growth.
Government and central bank officials have repeatedly denied any intervention in BI policymaking.
After Djiwandono's nomination, Purbaya again offered an assurance that BI would stay independent and would not fund government programmes.
BI has been in a monetary easing cycle since 2024, cutting interest rates by a total of 150 basis points to lift economic growth. BI is expected to keep rates unchanged on Wednesday to limit further rupiah pressure.
WHERE IS THE RUPIAH HEADING?
Some analysts believe the currency could remain under pressure this year, facing short-term headwinds from seasonal dollar demand for imports and dividend payments.
However, they also said support could come from BI's pledge to continue intervention to defend it.
BI had $156.5 billion in foreign exchange reserves at the end of 2025, close to an all-time high. That could rise once the government's plan to tighten rules on retention of export earnings takes effect.
The finance minister said the rupiah would strengthen going forward, reflecting Indonesia's strong economic fundamentals.
WHAT IS THE IMPACT ON INDONESIA'S ECONOMY?
So far, the rupiah's weakness has had limited impact on inflation, which has kept within, or even, below the central bank's target range since mid-2023.
However, continued weakness could hurt sectors that import a large share of raw materials, such as pharmaceuticals, cosmetics and steel, says Erwin Taufan of the Indonesian National Importers' Association.
Manufacturing, finance, electricity and gas supply, and mining industries have the highest external debt in the private sector, BI figures show.
Purbaya said the economic impact from the depreciation was "minimal".
Typically, the rupiah's depreciation will also mean a higher fuel subsidy bill and external debt payment costs, that could further pressure the budget deficit.
