JAKARTA - PT Kustodian Sentral Efek Indonesia (KSEI) recorded a significant growth in the number of capital market investors until December 19, 2025, which was recorded at 20,129,679 Single Investor Identification (SID), an increase of around 35 percent compared to the same year earlier which amounted to 14,871,659 SID.
KSEI President Director Samsul Hidayat said that the increase reflected the success of the socialization efforts carried out by KSEI in introducing the capital market to the public.
He added that this positive response encourages the capital market to be increasingly sought after as an investment option, both in stock instruments, debt instruments, and mutual funds.
"If we look at the end of 2024, the figure is only 14.8 million, and currently the figure has reached 20,129,679 SID. It has grown by about 35 percent in 2025 alone," he said in a media briefing, Tuesday, December 23.
He explained that the largest investor growth came from mutual fund instruments and based on KSEI data, the number of mutual fund investors became 18,990,746 SID, an increase of 35 percent from the previous year of 14,033,037 SID.
Meanwhile, the number of stock investors also increased to 8,504,076 SID by 33 percent compared to 2024 which was 6,381,444 SID.
However, Samsul emphasized that some mutual fund investors are also stock investors.
"The most investors are investors in Mutual Funds, namely 18,990,000 which is that it is diagonal. So some of these investors are also equity investors (stock market) namely at 8,504,000," he said.
The lowest growth was recorded by investors in State Securities (SBN) which increased by 17 percent to 1,405,712 SID compared to 2024 which was 1,198,821 SID.
In total, the number of SID from all instruments was recorded as 24,925,649, or an increase of 27 percent compared to the previous year which reached 19,598,704 SID.
In terms of regional distribution, Java Island still dominates with a share of 68.91 percent of the total national investors and the value of investor assets on Java Island reached IDR 6,400.59 trillion or equivalent to 94.42 percent of the total assets of the capital market in Indonesia.
Furthermore, the second position is occupied by the island of Sumatra with a contribution of 16.29 percent of investors and an asset value of Rp. 138.57 trillion, or about 2.04 percent of the total national assets.
"Java seems to have decreased compared to 2024, which is 69.3 percent, while currently it is 68.9 percent. Well, this may be due not only to a decrease, but also to a change in the trend of opening accounts or investor participation with possibly rising investors, for example in Sumatra, from last year only 15.4 percent now has become 16.29 percent with a total asset of Sumatra Rp110 trillion," he added.
