PT Bursa Efek Indonesia (BEI), the operator of the Indonesian capital market, has officially announced a landmark regulatory shift that will lower the minimum share price limit from the longstanding threshold of Rp50 down to Rp1 per share. This major structural update is scheduled to take effect starting Monday, September 28, 2026. Alongside this historic reduction in the minimum trading tick and floor price, the bourse will implement comprehensive adjustments to the Auto Rejection mechanisms governing Equity-Type Securities and Infrastructure Investment Funds (DINFRA) traded across both the Regular Market and Cash Market.
The initiative marks a pivotal milestone in the evolution of Indonesia’s financial markets, designed to align local trading frameworks with more flexible international standards. By allowing fundamentally suppressed or highly liquid low-priced equities to trade at true market-clearing levels below the traditional Rp50 floor, the exchange aims to resolve long-standing pricing distortions, improve overall portfolio management flexibility for retail and institutional investors alike, and stimulate trading activity across micro-cap segments.
Background Context and Strategic Rationale
For decades, the Rp50 minimum share price restriction served as an artificial pricing floor for Indonesian equities, colloquially known in the market as "gocap" stocks. While this rule was originally instituted to protect inexperienced retail investors from extreme volatility and to maintain administrative simplicity within trading systems, it inadvertently created significant market inefficiencies. Companies whose fundamental valuations had deteriorated substantially—or whose share prices had naturally drifted downward due to corporate restructuring, dilution, or prolonged operational challenges—became trapped at the Rp50 level.
This artificial floor prevented true price discovery, trapping capital in illiquid assets where bid-ask spreads widened indefinitely because sellers could not clear their holdings below Rp50, and buyers saw no fundamental value at that price point. Consequently, millions of rupiah in investor capital remained frozen. Furthermore, it discouraged issuers from engaging in corporate actions such as stock splits or rights issues that might otherwise rationalize their capital structures.
According to Elsierra Putri Yosita, Corporate Secretary of BEI, the policy shift will fundamentally transform how low-priced assets are transacted. "Stocks that were previously restricted to a floor price of Rp50 can now be traded within a much wider price range. This is intended to enhance the quality of price discovery, drive higher market liquidity, and provide market participants with greater flexibility in managing their investment portfolios," Yosita stated during an official briefing in Jakarta.
Detailed Breakdown of Auto Rejection Adjustments
To accommodate the new Rp1 minimum price boundary while maintaining orderly markets and safeguarding investors against runaway volatility, BEI has restructured its Auto Rejection Atas (ARA) and Auto Rejection Bawah (ARB) parameters. The rollout of these automated circuit breakers is divided into a transitional phase lasting through the end of 2026, followed by a permanent structural phase beginning in early 2027.
Phase One: Transition Period (September 28, 2026 – December 31, 2026)
During the initial months following the implementation, the exchange will maintain an asymmetric ARB framework of 15 percent for most equities priced above Rp10 to cushion the market against sudden panic selling. However, specific boundaries are established for the newly enabled ultra-low price tiers:
- For shares trading within the Rp1 to Rp10 range, both ARA and ARB are strictly capped at a fixed nominal value of Rp1.
- For shares priced above Rp10 up to Rp200, the ARA is set at 35 percent, while the ARB remains asymmetrical at 15 percent.
- For the mid-tier range spanning above Rp200 to Rp5,000, the ARA is set at 25 percent and the ARB at 15 percent.
- For premium blue-chip and high-priced equities exceeding Rp5,000, the ARA is established at 20 percent alongside the standard 15 percent ARB.
Phase Two: Full Symmetric Implementation (Starting January 1, 2027)
Effective January 1, 2027, the exchange will transition to a fully symmetric Auto Rejection framework across all pricing tiers, aligning downside protection symmetrically with upside potential:
- Equities priced between Rp1 and Rp10 will retain their fixed Rp1 boundary for both ARA and ARB.
- For shares valued from Rp11 up to Rp200, both ARA and ARB will be standardized at 35 percent.
- For the tier covering shares above Rp200 to Rp5,000, both upper and lower auto-rejection limits will be set at 25 percent.
- For top-tier securities trading above Rp5,000, both ARA and ARB will be harmonized at 20 percent.
Modifications for Infrastructure Investment Funds (DINFRA)
In tandem with equity adjustments, BEI has overhauled the regulatory boundaries governing Infrastructure Investment Funds (Dana Investasi Infrastruktur or DINFRA). Previously, DINFRA units priced above Rp50 were subject to a uniform ARA and ARB limit of 10 percent.
Under the revised framework, DINFRA instruments experiencing severe price compression will follow a tiered structure similar to equities:
- DINFRA units trading within the Rp1 to Rp10 price bracket will operate under a fixed ARA and ARB limit of Rp1.
- For units priced above Rp10, the standard ARA and ARB boundaries will be maintained at 10 percent.
Regulatory Foundation and Legal Framework
The sweeping market reforms are legally anchored by two primary Decrees issued by the Board of Directors of PT Bursa Efek Indonesia. The principal regulation is detailed in Directors’ Decree Number Kep-00136/BEI/09-2026, which formally amends BEI Regulation Number II-A concerning the Trading of Equity-Type Securities. These legal instruments were formulated following extensive consultations with the Financial Services Authority (Otoritas Jasa Keuangan or OJK) to ensure that technological systems, clearing and settlement mechanisms through PT Kliring Penjaminan Efek Indonesia (KPEI), and depository services via PT Kustodian Sentral Efek Indonesia (KSEI) are fully synchronized to handle fractional and multi-tiered micro-pricing orders.
Market Implications and Analytical Outlook
Financial analysts and market observers have broadly welcomed the structural reform, noting that it aligns the Indonesian bourse with mature regional and global exchanges where sub-penny and low-unit pricing models are common.
Enhanced Price Discovery and Capital Unfreezing
The most immediate impact of the policy will be felt by stagnant equities that have languished at the Rp50 mark for years despite lacking underlying operational viability or investor interest. By enabling these stocks to clear at natural market levels—whether that is Rp40, Rp15, or even Rp2—market forces can accurately price corporate risk. Investors holding these assets will finally possess the liquidity required to exit positions, realize capital losses for tax or portfolio rebalancing purposes, or accumulate shares at distressed valuations if turnaround catalysts emerge.
Heightened Retail Participation and Speculative Dynamics
While institutional investors will benefit from cleaner portfolio valuation metrics, market analysts caution that the introduction of stocks priced between Rp1 and Rp10 will inevitably attract heightened speculative trading, frequently referred to in local parlance as "saham gocap" or penny stock trading. The low nominal capital required to acquire large volumes of shares in this tier may entice retail day traders seeking high-beta returns. However, the implementation of strict fixed-value limits (Rp1 bands) and asymmetric circuit breakers during the initial transition phase is expected to mitigate catastrophic systemic losses while traders adapt to the new volatility profile.
Operational Adaptation for Brokerage Firms
Member securities firms (brokerage houses) have spent months upgrading their order routing systems, front-end trading applications, and risk management modules to process orders priced in single-digit rupiah values. Back-office accounting, portfolio valuation algorithms, and margin calculation engines must accurately account for the widened tick sizes and modified rejection boundaries to prevent execution errors when trading resumes under the new rules on September 28, 2026.
Conclusion
The reduction of the minimum share price limit to Rp1 represents a bold and necessary modernization of Indonesia’s capital market infrastructure. By systematically removing artificial price floors, BEI is fostering a more transparent, efficient, and market-driven ecosystem. As the implementation date of September 28, 2026, approaches, all market participants—from retail investors and brokerage houses to institutional asset managers—stand poised to navigate a revitalized trading landscape where asset prices reflect true economic realities.
