Thailand equity markets.

A Thai block trade moves a large line of SET-listed stock in a single negotiated transaction — off the continuous order book, on the exchange’s Big Lot Board at an agreed price — so a holder can exit, or an acquirer build a position, without walking the screen. Black Haven can take the line onto its own book, giving the seller a clean, priced exit while the substantial-shareholder reporting that follows a large transfer is managed around the print.

On the Big Lot Board a negotiated line is crossed away from the order book and the details are reported into SET’s trading system, so the print does not move the visible price on the way through. Size is read against the name’s daily turnover — SET50 and SET100 lines in energy, banking and telecoms absorb a large block more readily than mai or thin small-caps. Where the seller is foreign, whether the line moves as ordinary shares, foreign-board (F) shares or NVDRs shapes both pricing and the reporting that follows. Settlement runs T+2, and a 5% substantial-shareholder report may be triggered by the transfer.

Thailand · Block Trades

What holders ask about Thailand.

01Does a block trade in Thailand have to be disclosed?
A large transfer can cross the 5% substantial-shareholder threshold, which is reportable to the SEC under Notification TorJor. 7/2552, and a further report follows at each 5% change. The Big Lot Board trade itself is reported into the exchange’s system. We work out which reports the print triggers, and their timing, before the line is crossed.
02How large a line can I move in one block?
It depends on the name. A SET50 or SET100 constituent with deep daily turnover can take a substantial line in a single print; a mai-listed or thinly traded stock is placed more carefully, sometimes in stages. Because Black Haven can take the position onto its own book, the exit is priced against the specific line rather than left to the screen.
03How do you execute a Thailand block trade?
We work the line off the order book, off-market or at a negotiated price, and the block is then printed to Stock Exchange of Thailand (SET) under its block-trade rules. Black Haven Investments can take all or part of the risk on the line, so the seller achieves a clean exit at an agreed price.
04How large a block can you handle in Thailand?
It depends on the stock’s free float, daily traded volume and volatility. We assess each line on its merits and indicate a workable size and price range after reviewing the position.
05Does the block trade have to be disclosed?
Often, yes. A substantial transfer by a significant shareholder is generally disclosable under the relevant regime overseen by SEC (Thai). We manage the sequencing and wording of any required notification around the trade.
06Can you finance the buyer of the block?
Yes. A block can be paired with a stock loan to the acquirer, so the newly acquired Thailand-listed line serves immediately as collateral for the financing that funds it.
07What is the settlement cycle for a Thailand block trade?
The negotiated block is printed to Stock Exchange of Thailand (SET) under its block-trade rules and then settles on the standard T+2 cycle. We coordinate the print, the settlement and any financing legs so the line moves cleanly.
08At what level must a block be disclosed in Thailand?
The principal threshold is 5%, under SEC Notification TorJor. 7/2552 overseen by SEC (Thai). A crossing by a substantial holder is notifiable; we sequence the print and the notice.
09Can you execute a block for a foreign or offshore seller?
Yes. The line is held with a qualified custodian and the block printed to Stock Exchange of Thailand (SET); we manage cross-border custody, settlement and the disclosure that attaches to a substantial transfer.
10How quickly can a Thailand block be executed?
It depends on the stock’s liquidity and the size of the line relative to daily volume. Once mandated, many blocks are worked and printed within days; thinner lines are paced to limit market impact.

What Is a Block Trade, and How Does One Work?

A block trade is the off-market sale of a large line of listed shares at a negotiated price, executed bilaterally and printed under exchange rules to avoid moving the open market.

How Do You Sell a Large Block of Shares Without Moving the Price?

A large block is sold without moving the price by taking it off the open order book — negotiating off-market at an agreed price, often with a liquidity provider taking the risk, and printing under exchange block rules.

Do Block Trades Have to Be Disclosed?

Often yes. Once a significant shareholder crosses a market’s substantial-holding threshold, a block sale is generally notifiable to the regulator within a set window, with thresholds varying by jurisdiction.
