Why the Indonesia Stock Exchange Is Delaying Its Landmark Rp 1 Stock Price Rule

JAKARTA, Investortrust.id — The Indonesia Stock Exchange (IDX) has delayed the rollout of its sweeping market reform that eliminates the Rp 50 ($0.0031) minimum share price floor, pushing back the go-live date to late September.

The policy shift, initially scheduled to take effect on Sept. 7, 2026, will permit equities in the regular and cash markets to trade down to Rp 1 ($0.00006). Exchange leadership decided to pause the rollout after system simulations revealed that a handful of local brokerages were not yet technically prepared for the transition.

Scrapping the long-standing Rp 50 ($0.0031) price floor marks a watershed moment for Southeast Asia’s largest equity market. By allowing equities to trade as low as Rp 1 ($0.00006), the Indonesia Stock Exchange (IDX) aims to unlock trapped liquidity and attract heavyweight global index providers like MSCI and FTSE Russell. However, the temporary delay highlights the operational hurdles domestic brokerages face in upgrading their systems to handle high-frequency, penny-stock volatility.

Broker Readiness Prompts Launch Delay

During mock trading runs conducted on Aug. 22 and Aug. 29, 2026, the vast majority of exchange members proved ready, but a critical minority lagged behind. Out of the bourse’s registered brokerage firms, 83 passed the trials, while eight firms failed to meet operational benchmarks.

IDX President Director Jeffrey Hendrik emphasized that the exchange will not rush the implementation until every participant can guarantee seamless trade execution. The bourse is now providing hands-on technical assistance to the lagging brokerages.

“We are in intensive communication with the exchange members that are not yet ready, offering full guidance and assistance,” Hendrik said on the sidelines of a corporate event at the IDX Building in Jakarta on Tuesday, Sept. 1, 2026. “Our target for going live has moved to the third or fourth week of September because we must wait for the full readiness of all exchange members.”

Unlocking Liquidity and Tripling Trading Turnover

The reform targets underperforming stocks that have historically remained stuck at the Rp 50 floor, where trading activity often evaporates into severe illiquidity. Bourse officials project that moving these names from the Special Monitoring Board's call-auction mechanism into the standard continuous auction will dramatically re-energize the market.

Exchange projections indicate that market turnover and transaction frequency could surge two- to threefold once the new price bands and updated auto-rejection classifications take effect. This wider price discovery mechanism will allow market forces to value distressed or micro-cap assets more accurately.

Courting Global Heavyweights: MSCI and FTSE

Beyond clearing out local market bottlenecks, the move plays directly into Indonesia’s broader campaign to elevate its standing among global index compilers. The IDX has already submitted eight accelerated capital market reform action plans designed to tackle specific transparency and governance concerns raised by global benchmark providers.

Hendrik voiced strong confidence that major index compilers, including MSCI and FTSE Russell, will welcome the structural upgrade once the full system goes live.

“From our focus group discussions to market socializations, the feedback we received has been overwhelmingly positive,” Hendrik explained during the press briefing. “When market feedback is this positive, we are confident that MSCI, FTSE, and other global index providers will respond just as positively.”

Hendrik reiterated that the regulatory overhaul is designed for the long-term health of the domestic market rather than merely satisfying external rating requirements. The ultimate objective remains delivering institutional-grade transparency, superior corporate governance, and efficient price discovery to both domestic and international investors.
