Small Accounts Surge in Number, But Jumbo Deposits Drive Growth

The growth of public savings shows a different pattern across customer groups. Accounts with balances below Rp100 million are increasing in number, but their total value is only growing slightly. Conversely, the number of jumbo accounts above Rp5 billion is growing more slowly, but the nominal funds stored in them are surging at a much higher rate.

Based on data from the Indonesia Deposit Insurance Corporation (LPS), total public deposits reached Rp10,329.93 trillion as of May 2026, growing 13.4% year-on-year (yoy). The main driver of this increase came from deposits above Rp5 billion. The value of this group’s savings reached Rp6,026.75 trillion, up 21.4% yoy.

However, the number of accounts in this group was only 155,438, or about 0.02% of total banking accounts. The growth in the number of these accounts was 7.2% yoy. On the other hand, accounts with balances below Rp100 million totalled 674,640,099, representing approximately 98.9% of all banking accounts. Their number grew higher, at 8.9% yoy.

Yet, the growth in the number of these accounts was not matched by a proportional increase in deposit value. The nominal savings of the sub-Rp100 million group only reached Rp1,143.26 trillion, rising by 4.9% yoy. Based on bank size, deposits at KBMI 2 banks grew the highest at 20.9% yoy, followed by KBMI 4 at 16.4% yoy. KBMI 3 and KBMI 1 grew 7.6% yoy and 6.8% yoy, respectively. In terms of ratio, KBMI 4 remains the public’s favourite place to store money, contributing 53.7% to third-party funds, followed by KBMI 3 at 27%, KBMI 2 at 10.2%, and KBMI 1 at 9.1%.
