In September 2026, Indonesian bank loans grew 13.26% from a year earlier. Deposits grew only 8.22%. That gap is the story. This post explains bank credit growth in Indonesia in plain words, and why economists watch it before they watch almost anything else.
Credit is just another word for bank loans. Home loans, business loans, car loans, credit cards. All of it.
Credit growth is how much the total pile of loans grew compared with a year ago. Bank Indonesia (BI) and the financial regulator OJK both publish it every month.
Here is the reading from the data we found, all as reported in the press, not from the original releases:
| Month (2026) | Loans, year on year | Who reported it |
|---|---|---|
| February | 9.37% | BI (via Bisnis.com) |
| March | 9.49% | OJK |
| June | 12.67% (Rp9,080.9 trillion) | OJK |
| July | 13.58% (Rp9,135 trillion) | OJK |
| August | 13.65% | BI and OJK |
| September | 13.26% | BI |
Sources: Bisnis.com, Kontan, Investortrust, BCA Sekuritas and Metro TV summaries of BI and OJK data, retrieved 31 October 2026. We saw search summaries only and did not open the official releases.
Read it like a speedometer. Loan growth sped up from about 9% in the first quarter to about 13% by mid-year.
A loan is spending in advance.
When a company borrows to build a factory, the spending comes next: cement, steel, wages. When a family takes a home loan, the spending comes next too: furniture, renovation, fees.
So loans often move before the activity they pay for. That is why credit growth is called a leading indicator: a number that tends to turn before the economy does.
It is not a crystal ball. Loans can also rise because prices rose, or because a few big borrowers drew down at once. Treat it as a clue, not a verdict.
BI said the September rise was backed by investment loans, working capital loans and consumer loans (BCA Sekuritas summary of BI data). Investment loans matter most here, since they fund things that last.
Banks lend out money that people and firms deposit. So you need both sides.
The loan-to-deposit ratio (LDR) is loans divided by deposits. If a bank holds Rp100 in deposits and has lent Rp88, its LDR is 88%.
OJK reported the industry LDR at 88.38% in July 2026, up from a month and a year earlier (Kontan). In September, deposits grew 8.22% while loans grew 13.26% (BI).
Here is a simple illustration. This is NetWort arithmetic, not a forecast, and it mixes the July LDR with September growth rates:
When loans outrun deposits, banks have less spare cash. They may pay more to attract deposits, or lend less. Bisnis.com's headline on 21 October 2026 also said BI pointed to Rp2,562 trillion of idle funds in the system. We only saw the headline, so we cannot explain what it counts.
BI can nudge lending. It held the BI Rate at 5.75% on 21 October 2026, and raised its Deposit Facility rate to 5.00%. Bisnis.com also reported that BI had paid out Rp458.5 trillion in liquidity incentives to banks up to early October 2026, meant to encourage lending.
Rate changes take time to reach your loan. We showed that in our post on how the BI Rate reaches bank lending rates. For how the bank reserve requirement frees up cash to lend, read our GWM explainer. To see how the budget and BI share the work, see fiscal vs monetary policy in Indonesia.
Loans also depend on jobs. For how to read the unemployment rate, see Indonesia's jobs data explained.
You do not need to trade on this. But it helps you read the news.
Remember these numbers will move. OJK and BI update them every month, and the next release can change the picture.
Open NetWort's Macro page. Put the BI Rate, inflation and the rupiah next to each other, then compare them with the latest credit growth number in the news. Do the rate and the loans tell the same story?
