South Korea equity markets.

A Korean block trade moves a large line of KRX-listed stock in a single negotiated transaction — off the continuous order book, 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 5% reporting that follows a substantial transfer is managed around the print.

Korea provides for negotiated block trading away from the continuous auction, including in the after-market session, which is how sizeable lines change hands without moving the last price. Where a transfer crosses the 5% threshold — or shifts an existing holding by 1% or more — a large-shareholding report to the FSC and the KRX follows within the statutory window, and where the counterparties are corporate insiders separate ownership-reporting duties apply. Size sits comfortably against KOSPI 200 turnover; on KOSDAQ and KONEX names a block is calibrated more carefully to daily volume. Settlement is T+2.

South Korea · Block Trades

What holders ask about South Korea.

01Does a block trade in Korea have to be disclosed?
Where the trade takes your interest to 5% or more of a company’s voting shares, or moves an existing 5%-plus holding by 1% or more, a large-shareholding report to the FSC and the KRX follows within the statutory window; company insiders carry separate ownership-change reporting duties. The negotiated block itself prints off the continuous order book. Black Haven maps which duties apply to both sides before execution.
02How large a line can be crossed as a single block?
Against KOSPI 200 large-caps a substantial line can be crossed at one agreed price without disturbing the last screen print, because daily turnover is deep. On the volatile KOSDAQ segment and thin KONEX names the size is worked against available volume and wider spreads, and may be staged. Black Haven sizes the block to the specific name’s liquidity before quoting.
03How do you execute a South Korea block trade?
We work the line off the order book, off-market or at a negotiated price, and the block is then printed to Korea Exchange (KRX) 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 South Korea?
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 FSC / FSS. 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 South Korea-listed line serves immediately as collateral for the financing that funds it.
07What is the settlement cycle for a South Korea block trade?
The negotiated block is printed to Korea Exchange (KRX) 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 South Korea?
The principal threshold is 5%, under FSCMA Art. 147 overseen by FSC / FSS. 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 Korea Exchange (KRX); we manage cross-border custody, settlement and the disclosure that attaches to a substantial transfer.
10How quickly can a South Korea 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.
