Sell a large IDX block, off the screen.
When you genuinely want to exit, a block trade places a large Indonesian shareholding privately — at an agreed price, with controlled disclosure, and without cratering the screen.
What an IDX block trade actually is.
A block trade is a privately-negotiated sale of a large parcel of IDX-listed shares, matched with an identified buyer and reported to the Exchange through the Negotiated Market — rather than worked through the open order book.
A large holder who sells on the screen is their own worst counterparty. The order moves the price, signals intent to the market, and is filled in pieces at progressively worse levels. A block trade avoids all of that: the position is placed in a single negotiated transaction with a buyer who wants the size, at a price agreed in advance, and crossed on the Negotiated Market (Pasar Negosiasi).
The result is a clean exit — or a clean reduction — with the disclosure and timing controlled rather than left to the order book to dictate.
The screen is built to price small orders well and large ones badly. A block is the opposite.
Why off-screenThe moment a block trade is the right tool.
A block trade is for the holder who has decided to part with a position — fully or in part — and wants to do it well. If you would rather keep the shares, a stock loan is the better instrument.
- 01A genuine exit. You are stepping away from a holding and want the proceeds in hand, cleanly.
- 02Diversification. Reducing a concentrated single-name position into a broader base of wealth.
- 03Succession & estate planning. Realising value for a generational transition or an estate settlement.
- 04Strategic disposal. A listed corporate unwinding a treasury or cross-holding without divestment noise.
- 05Bringing in a partner. Placing a strategic stake with a named long-term buyer.
- 06Post-lock-up sell-down. A founder or pre-IPO holder reducing once contractually free to sell.
How a block is priced and crossed.
Price is discovered against the prevailing screen and the depth of buyer demand — not dictated by a rate card. Execution is matched, crossed, and settled through the Exchange's own infrastructure.
Premium or discount
Usually a negotiated discount (occasionally a premium) to the volume-weighted or last-traded price, reflecting block size, liquidity, and free float.
Identified counterparty
The block is matched with a buyer who wants the size — an institution, strategic holder, or family office — discreetly approached.
Negotiated Market
The trade is crossed on the Negotiated Market (Pasar Negosiasi) and reported to the IDX, away from the regular order book.
KSEI & KPEI
Clearing and book-entry settlement run through KPEI and KSEI in the C-BEST system, on agreed timelines.
Single or phased
Larger blocks may be staged over time or syndicated across more than one buyer to protect price.
Controlled signalling
Identity and intent are protected until the trade is done, limiting the market read on the sale.
What a block can trigger, mapped before execution.
A block is structured so that disclosure and takeover consequences are known before, not after, the cross.
Acquisitions or disposals crossing the 5% substantial-shareholding threshold — and subsequent changes — are reportable to OJK under POJK No. 3/POJK.04/2021. Where a buyer acquires control of the company — broadly more than 50% of the voting shares, or the ability to determine its management and policy — the mandatory tender offer and takeover provisions (POJK No. 9/POJK.04/2018) may be engaged, together with related concert-party considerations.
For both seller and buyer, these consequences are mapped at the structuring stage, in conjunction with Indonesian counsel, so the cross proceeds cleanly. See our note on Indonesian disclosure mechanics.
This is a general description, not legal advice. Specific obligations are confirmed with Indonesian counsel as part of each transaction.
