On 29 September 2026, the Indonesian government asked investors to lend it money. Investors offered Rp42,87 trillion. The government took Rp28,8 trillion.
That gap tells you something. So does the yield the government agreed to pay.
Every two weeks or so, the news reports a government bond auction result. Most people scroll past it. This guide shows you how to read it in about five minutes.
A government bond is a loan you give the state. The state pays you interest, then returns your money on a set date. In Indonesia, these bonds are called SBN (Surat Berharga Negara). The main kind sold in auctions is SUN (Surat Utang Negara).
The state needs to borrow regularly, partly to cover its budget gap. We explain that link in our post on how bond issuance moves yields.
So the Ministry of Finance holds auctions. The part of the ministry that runs them is the debt office, DJPPR. Instead of fixing one price, it lets investors compete on price. That is how the market, not the government, sets the interest rate.
Yield is the return a bond pays you, as a percentage per year, based on the price you pay.
When investors want a bond badly, they accept a lower yield. When they are cautious, they ask for a higher one. So a falling yield at auction means demand is strong.
Here is the part that confuses people. The government is the borrower. A higher yield means it pays more to borrow.
Bank Indonesia runs the auction system. It is an open auction using a multiple price method, according to DJPPR notices that cite regulation PMK 168/2019 (IDN Financials).
In plain words, bidders say how much they want and what yield they will accept. Then:
In principle anyone can bid. In practice, bids go through registered participants such as banks and securities firms.
This is an invented example, not a real auction. It shows the multiple price method.
The government wants to raise Rp10 trillion from one bond. Bids arrive:
| Bidder | Amount | Yield asked |
|---|---|---|
| A | Rp4 trillion | 7,00% |
| B | Rp4 trillion | 7,10% |
| C | Rp4 trillion | 7,20% |
The government fills the lowest yields first. A gets all Rp4 trillion at 7,00%. B gets all Rp4 trillion at 7,10%. C gets the last Rp2 trillion at 7,20%.
Each winner pays their own yield. That is the multiple price method. The weighted average yield is the average of the winning yields, weighted by amount:
(4 × 7,00 + 4 × 7,10 + 2 × 7,20) ÷ 10 = 7,08%
Non-competitive bidders would get 7,08%. The weighted average yield is the headline number you see in the news.
Two figures appear in every result.
Incoming bids are the total offers investors made. Awarded is the amount the government accepted.
Before the auction, DJPPR also sets an indicative target, the amount it hopes to raise. News reports compare incoming bids with that target (Kontan).
The ratio of bids to the amount raised is the bid-to-cover ratio. Outlets use it in slightly different ways, so check which base a report uses.
Here is what the press reported, based on DJPPR's release (Bisnis.com, via a search summary retrieved 13 October 2026):
| Item | Figure |
|---|---|
| Incoming bids | Rp42,87 trillion |
| Awarded | Rp28,8 trillion, across nine series |
| Bids divided by awarded (NetWort arithmetic) | About 1,49 times |
| Most popular series | FR0110, bids of about Rp12,94 trillion |
| Highest bid-to-cover on a series | FR0105, 2,75 times |
| Settlement | 1 October 2026 |
Yields of the winning bids:
FR means a fixed-rate bond that pays the same coupon until it matures. SPN means a short bill under one year. Longer bonds usually pay more, because you wait longer to get your money back.
One result alone says little. Compare it with the one before.
On 21 July 2026, bids reached Rp67,89 trillion and the government took Rp32 trillion, against an indicative target of Rp32 trillion (Bisnis.com). That is about 2,12 times, using the same arithmetic.
So in September, bids were lower relative to what was sold. Investors were less crowded in. The newer series also carried yields around 7,1% to 7,3%, while the July series reported FR0109 near 7,26% and FR0108 near 7,29% (search summary). Yields on different series are not directly comparable, since each bond has its own maturity.
Auction yields feed into other rates. Banks, companies and the state use them as a reference when pricing loans and new bonds.
Foreign buyers also watch these results. Our post on foreign ownership of Indonesian government bonds shows how that shapes the rupiah.
If you want to hold bonds yourself, retail bonds work differently. They are sold in offering periods, not through this auction. Read our guide to ORI and SBR retail bonds.
When the next result lands, ask four questions:
Open the NetWort Macro Context page. Look at the bond yields next to the BI Rate and USD/IDR. Then compare them with the numbers in the next auction result.
We could not open the DJPPR or news sites directly from our research environment. The figures above come from search summaries of those reports, so check the DJPPR announcement for the official numbers.
