Indonesia forex reserves rise to $146.8 billion in October 2026

Key takeaways

• Bank Indonesia said on Nov 6, 2026 that Indonesia's foreign exchange reserves stood at $146.8 billion at the end of October 2026, up from $146.3 billion at the end of September 2026.
• The central bank attributed the increase to government external loan disbursements and tax and service receipts, partly offset by government external debt repayments and its rupiah stabilisation policy.
• The reserves covered 5.3 months of imports, or 5.2 months of imports plus government external debt payments, against an international adequacy standard of about three months, Bank Indonesia said.
• The October 2026 level remained about $10.3 billion below the record of roughly $157.1 billion set in March 2025, according to Trading Economics data.
• The rupiah's JISDOR reference rate was Rp18,130 per US dollar on Nov 6, 2026, compared with Rp18,094 on Nov 5, 2026, Receh.in reported, citing Bank Indonesia's JISDOR data.

Indonesia's reserve buffer edged higher in October 2026: the end-month position of $146.8 billion was about $0.5 billion above September's, according to a statement Bank Indonesia (BI) issued on Friday, Nov 6, 2026. CNN Indonesia published the figures at 13:04 WIB (06:04 UTC) that day.

The release matters for investors in Indonesian bonds, equities and the rupiah because reserves are the pool of dollars the central bank can draw on to smooth currency moves. BI's own description of what moved the number in October 2026 included both inflows from government borrowing and outflows linked to debt repayment and currency stabilisation.

Indonesia foreign exchange reserves: the October 2026 numbers

The table below collects the figures from Bank Indonesia's Nov 6, 2026 statement, as reported by ANTARA, CNN Indonesia and StockWatch, alongside earlier monthly readings published by Trading Economics.

On those monthly figures, the reserves have moved within a narrow band of $145.3 billion to $146.8 billion from July 2026 to October 2026. Trading Economics described the October 2026 reading as the highest since March, without stating the year in that line; Bullquill has not independently confirmed which month it refers to.

What drove the October 2026 change

Bank Indonesia gave four reasons for the movement, according to ANTARA and CNN Indonesia, which both carried the central bank's statement:

• Government external loan disbursements added to reserves.
• Tax and service receipts also added to reserves.
• Repayment of maturing government external debt reduced them.
• Rupiah stabilisation, which ANTARA described as interventions to stabilise the currency amid volatile global financial markets, also weighed on the total.

Ramdan Denny Prakoso, Executive Director of Bank Indonesia's Communication Department, said in a written statement on Nov 6, 2026 that the increase was offset by payments on government foreign debt that had fallen due, StockWatch reported. Bank Indonesia did not publish a breakdown of how much each factor contributed, in any of the reports Bullquill reviewed as of 10:50 UTC on Nov 6, 2026, the time stamp of the ANTARA English story.

Why the net figure hides gross flows

A $0.5 billion net rise can conceal much larger flows in each direction. Loan disbursements and tax receipts are inflows; debt service and dollar sales in the currency market are outflows. Because BI did not disclose the size of each component for October 2026, the size of its currency intervention during the month cannot be read from the headline number alone.

How adequate are 5.3 months of import cover?

Import cover divides the reserve stock by average monthly imports. It is a common, simple test of how long a country could pay for its imports from its reserves alone if all other foreign currency income stopped. The three-month rule of thumb that Bank Indonesia cited is a minimum benchmark, not a target.

By that test, Indonesia's end-October 2026 position of 5.3 months is well above the floor, and BI said the reserves were above the international standard, according to ANTARA's English report. The second measure, 5.2 months, adds scheduled government external debt payments to the import bill, which makes it a slightly stricter test.

Import cover is only one yardstick. Analysts also compare reserves with short-term external debt and with the stock of foreign-held local assets that could leave quickly. Bank Indonesia's Nov 6, 2026 statement, as reported, did not include those ratios.

The rupiah backdrop in early November 2026

The reserves data arrived during a week of small moves in the rupiah's official reference rate. According to Receh.in, citing Bank Indonesia's JISDOR data, the reference rate was:

On those figures, the rupiah weakened about 0.20% on the reference rate on Nov 6, 2026 from the previous day, but ended the week marginally stronger than the Oct 30, 2026 level of Rp18,138. Bullquill covered the earlier pressure on the currency in its report on the rupiah trading near a record low amid MSCI-related outflows.

Monetary policy is the other half of the picture. At its Oct 20-21, 2026 meeting, Bank Indonesia kept the BI-Rate at 5.75%, with the deposit facility at 5% and the lending facility at 6.5%, CNN Indonesia reported. Governor Destry Damayanti said the decision was backed by stronger incentives for domestic non-deliverable forward (DNDF) hedging instruments, which she described as part of the bank's rupiah stabilisation strategy. Bullquill's coverage of that meeting is in Bank Indonesia's October 2026 rate hold.

What Bank Indonesia expects next

Bank Indonesia said it views the reserves as able to support the resilience of the external sector, according to CNN Indonesia. The central bank added that foreign capital inflows could continue, citing positive investor sentiment and attractive investment returns, and said it would keep coordinating with the government, ANTARA reported.

Those are the central bank's own expectations, not guarantees. The reserve figure for November 2026 will show whether the inflows BI described materialised.

What it means

For ASEAN investors, the October 2026 release offers three data points. First, on Trading Economics data the stock of reserves stayed within a $1.5 billion range from July 2026 to October 2026, about $10 billion below the March 2025 peak. Second, BI confirmed that rupiah stabilisation was one of the factors weighing on reserves in October 2026, so intervention remained part of its toolkit. Third, import cover of 5.3 months remained above the three-month benchmark BI cited.

The release also connects to the wider Indonesian macro picture. Third-quarter 2026 growth data from Statistics Indonesia are covered in Bullquill's Indonesia Q3 2026 GDP report, and the equity market reaction that day is in the Indonesia stocks daily brief for Nov 5, 2026. More coverage of the central bank is collected on the Bank Indonesia topic page.

What to watch next

• Bank Indonesia's end-November 2026 reserves figure; the October 2026 figure was released on Nov 6, 2026.
• Any breakdown BI provides of intervention, debt service and loan disbursements.
• The JISDOR reference rate published by Bank Indonesia on each trading day.
• Bank Indonesia's next Board of Governors decision on the BI-Rate and its DNDF incentives.
