Foreign Investors Can Own 99% of an IDX Bank Stock, But Only 20% of a Broadcaster

Bank Central Asia (BBCA) is one of the most widely held stocks on IDX, and foreign investors can legally own up to 99% of it. A broadcaster listed on the same exchange, in the same country, under the same investment law, caps foreign ownership at 20%. Same market, same rulebook in theory, wildly different ceilings in practice. If you assume every IDX sector treats foreign capital the same way, you're assuming wrong, and the actual foreign ownership limit for the sector you're looking at can change how much of a stock's float is even reachable by foreign money.
Indonesia doesn't decide foreign ownership sector by sector inside the stock exchange's own rulebook. The caps come from separate laws and regulations for each industry, then get applied to whichever companies in that industry happen to be listed on IDX. A bank follows banking law. A broadcaster follows broadcasting law. A palm oil company follows general investment regulation. IDX itself doesn't set the limit; it just lists the stock and lets the sector-specific cap apply.
The government's main tool for this is the Positive Investment List (Daftar Positif Investasi), issued under Presidential Regulation No. 10/2021. Instead of naming which sectors are closed to foreign money, as the old "negative list" did, it names which sectors carry a specific cap, and treats everything else as fully open by default.
Banking is the one most investors assume is locked down, since it touches the financial system directly. It's actually one of the more open sectors on paper. Under Financial Services Authority (OJK) Regulation No. 12/POJK.03/2021, Article 13 paragraph 2, a foreign country or foreign legal entity can own up to 99% of the paid-up capital of an Indonesian-incorporated commercial bank, according to OJK's own explanation reported by Bisnis Indonesia, corroborated by Katadata and CNBC Indonesia.
That 99% isn't automatic. OJK still has to approve the specific investor, and the regulation requires the foreign shareholder to commit to supporting Indonesia's economic development and to hold a minimum credit rating. But the ceiling itself, 99%, is far higher than most people expect for a sector this sensitive. That's why Bank Central Asia (BBCA), Bank Rakyat Indonesia (BBRI) and other IDX-listed banks can and do carry meaningful foreign shareholding without breaching any sector rule.
Media and broadcasting sit at the opposite end. Indonesia's Broadcasting Law (Law No. 32/2002) caps foreign capital in a private broadcasting institution at 20% of paid-up capital, and requires the controlling shareholder to be an Indonesian citizen or Indonesian legal entity, a rule reported by Kompas and corroborated by ANTARA and Tempo's coverage of the same rule. Print and press companies raising capital through the stock market carry a separate, slightly higher cap of up to 49%, reported by Bisnis Indonesia and CNN Indonesia, but 20% is the number that applies to a broadcaster itself.
That's a five-times-tighter ceiling than banking, in the same country, under the same general investment framework. The reasoning is different too: broadcasting caps exist to keep editorial and information control domestic, not to manage systemic financial risk the way a banking cap would.
At the other extreme, plantation companies, including palm oil, rubber, coffee and cocoa producers, are fully open to foreign ownership, up from a 95% cap under the previous rule, per Vistra's own summary of the 2021 regulation and corroborated by Emerhub. Most manufacturing sectors carry no foreign ownership cap either. Astra Agro Lestari (AALI), an IDX-listed palm oil producer, sits in a sector where, unlike a bank or a broadcaster, there is no ceiling at all on how much of it foreign investors could legally hold.
The Positive Investment List organizes every sector by its KBLI code (Klasifikasi Baku Lapangan Usaha Indonesia, Indonesia's standard industry classification), not by company name. To find the cap that applies to a specific IDX stock:
This matters most for a company that operates across more than one regulated activity, since the cap follows the specific licensed activity, not the sector the stock happens to be grouped under on a screener.
A sector's foreign ownership limit doesn't tell you whether a stock is a good or bad holding. It tells you something structural: how much of that company's shares foreign capital is legally permitted to absorb, which shapes how much foreign buying or selling pressure a stock can realistically see. A bank with a 99% ceiling has far more room for foreign inflows, and far more exposure to foreign outflows, than a broadcaster capped at 20%. That's a different dynamic from the day-to-day foreign buy and sell flow already moving the IHSG, and it sits upstream of it: the cap decides how much room that flow has to work with in the first place.
It's also a separate question from which sector a stock is grouped into on your screener in the first place. If you want to understand how IDX classifies a stock's sector before you even get to ownership rules, the IDX-IC sector classification explains how that grouping actually works.
Before you assume a stock's foreign ownership room based on its size or how well-known it is, check the sector it actually sits in on NetWort's Market page, where sector-level context sits alongside the price data.
