Bank Indonesia's $146.5 Billion in Reserves Isn't All Dollars. Some of It Is Gold

Bank Indonesia reported $146.5 billion in foreign reserves at the end of August 2026, up from $145.3 billion in July. If you picture that number as one giant pile of US dollar bills, you are picturing it wrong. Close to $11 billion of it is not currency at all. It is physical gold, sitting in vaults, counted as part of the same foreign reserves figure every headline quotes.
Most coverage of Indonesia's reserves only reports the one total. This looks at what is actually inside it, and why a central bank holds gold as a reserve asset at all.
Cadangan devisa, foreign exchange reserves, is not just a stash of foreign currency. Bank Indonesia's own reserve management framework groups it into four components: monetary gold (gold bars and coins meeting international purity standards, held at home or abroad), Special Drawing Rights (SDR, an IMF-issued reserve asset valued against a basket of five major currencies), Reserve Position in the Fund (RPF, Indonesia's own claim on the IMF from its membership contribution, redeemable for foreign currency on demand), and other reserves, mostly foreign currency deposits and government securities, which makes up the largest share.
Gold is the one component most reporting skips entirely, because the headline total does not break it out.
As of the second quarter of 2026, Bank Indonesia held 87.09 tonnes of monetary gold, up slightly from 87.04 tonnes in the first quarter, according to World Gold Council data compiled by Trading Economics. At the gold price prevailing in July 2026, that position was worth $11.38 billion, up from $11.29 billion in June as the gold price moved, even though the tonnage barely changed.
Set that $11.38 billion against July's $145.3 billion reserves total and gold works out to roughly 8% of everything Bank Indonesia holds as reserves. The rest is overwhelmingly foreign currency, plus small slivers of SDR and IMF reserve position.
Bank Indonesia added to this position during the year: it bought 2 tonnes of gold in the first quarter of 2026 alone, part of a global wave of central bank buying that totaled 244 tonnes across all central banks that same quarter, according to Kontan's reporting, corroborated by CNN Indonesia.
A US dollar deposit is still someone else's liability. It only has value because the issuer, ultimately the US government, stands behind it. Gold is not a liability of any government or institution. Nobody can default on it, freeze it by sanction the same way a foreign-currency account can be frozen, or devalue it by printing more, which is the core reason central banks treat it differently from every other reserve asset.
That is also why gold sits at the center of a broader shift happening across central banks worldwide, not just in Jakarta. The World Gold Council's 2026 Central Bank Gold Reserves Survey found that 89% of reserve managers expect global central bank gold holdings to keep rising over the next 12 months, and a record 45% expect their own institution's holdings specifically to increase. The reasons reserve managers gave were consistent: performance during a crisis, portfolio diversification, and a hedge against both inflation and geopolitical risk, none of which a currency deposit offers in the same way.
One number gets confused with Bank Indonesia's gold reserves constantly, so it is worth separating clearly. Indonesia sits on some of the largest gold deposits in the world still in the ground, commonly cited around 3,600 tonnes, largely tied to mines like Freeport's Grasberg complex. That is a geological resource estimate: gold ore that has not been mined yet.
It has nothing to do with the 87.1 tonnes Bank Indonesia actually holds as a financial reserve asset. One is rock underground with a market value if it is ever extracted, refined and sold. The other is a bar sitting in a vault, already counted as part of the nation's reserves today. Reporting on Indonesia's gold position sometimes blurs the two into one number, which overstates what the central bank itself is actually sitting on by roughly 40 times.
None of this changes how you should think about gold as a personal investment. Bank Indonesia holds gold for reasons specific to running a central bank: reserve diversification, crisis resilience, and reducing reliance on any single currency. Your own reasons for holding gold, if you have any, are probably different.
What is useful here is the reminder that a headline reserves number is never the whole picture. The same is true of the BI Rate, inflation, and the rupiah's exchange rate, the indicators that actually move month to month and shape what your own portfolio earns. NetWort's Macro Context page tracks the current BI Rate, Indonesian and US inflation, and USD/IDR in one place, so you can see where policy actually stands rather than reacting to a single number in isolation. If you want the fuller story on what Indonesia's reserves total has been doing and what it means for rupiah stability, this site's earlier look at the reserves slide and recovery covers that separately.
