The large number on this page is not a real-time measurement. Since October 2025, Indonesia's central government debt position is officially reported by the Ministry of Finance every quarter, typically five to seven weeks after quarter-end. What we do is simple: take the latest official release, then add to it linearly using this year's debt growth rate.
That rate is the difference between the last two quarterly debt positions, divided by the number of seconds between them. For the interest ticker, we use this year's budgeted debt-interest ceiling divided by the number of seconds in a year. Both are averages, not a daily cash flow: government securities are issued in biweekly auctions, and coupon payments fall on specific dates.
Because of that, the number ticking on your screen is an estimate. The small line under the counter — the last official position and its date — is always the more reliable figure. Every time a new release is published, the counter resets to that official number, so the estimate never drifts more than one reporting cycle.
The scope is central government debt: government securities (SBN) and loans, in both rupiah and foreign currency. It excludes state-owned enterprise debt, regional government debt, and contingent liabilities such as project guarantees. This definition follows Ministry of Finance reporting so the figures here can be compared directly with official documents.
The external-debt section uses US dollars, matching how Bank Indonesia reports it (SULNI), not a conversion from rupiah. It is a different measure from the rupiah figure above: it includes government securities (SBN) held by non-resident investors, but excludes domestic-held debt. The chart's quarterly points are taken from Bank Indonesia's monthly SULNI editions, at the end-of-March/June/September/December position each year.
