United Kingdom & Europe

Turkey equity markets.

A Turkey block trade moves a large line of Borsa İstanbul-listed stock in a single negotiated transaction — away from the continuous order book, at an agreed price — so a holder can exit, or an acquirer build a position, without walking the screen through a thin lira market. Black Haven can take the line onto its own book, giving the seller a clean, priced exit while the disclosure that follows a substantial transfer is managed around the print.

Borsa İstanbul runs a Wholesale Market for equity trades above a set size, executed to identified or unidentified counterparties away from the central order book — the venue through which a large line is placed without moving the screen. Size sits against single-stock turnover, which is high for BIST 30 names but thins quickly outside the large caps, so the block is priced to the real depth of the name. On the disclosure side, a transfer that carries a holder across 5% or a higher threshold under the Capital Markets Law No. 6362 is notifiable through the Central Registry Agency, and settlement runs T+2 through Takasbank, which sets when the transfer is final.

04 · FAQ
Turkey · Block Trades

What holders ask about Turkey.

01Does a block trade in Turkey have to be disclosed?
The trade itself clears through Borsa İstanbul’s market infrastructure, but the resulting change in ownership can be. Where a transfer takes a holder across 5% of voting rights — or a higher threshold, or below one — the position is notifiable under the Capital Markets Law No. 6362, filed through the Central Registry Agency within the prescribed window. Black Haven structures the print and sequences any notification around it.
02How is a large line placed without moving the price?
Through a negotiated block rather than the continuous order book. Borsa İstanbul’s Wholesale Market exists precisely for equity lots above a set size, and Black Haven can take the line onto its own book at an agreed price — giving the seller a single priced exit instead of feeding a thin lira order book that the size would otherwise move against them.
03How do you execute a Turkey block trade?
We work the line off the order book, off-market or at a negotiated price, and the block is then printed to Borsa İstanbul (BIST) 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 Turkey?
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 CMB (SPK). 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 Turkey-listed line serves immediately as collateral for the financing that funds it.
07What is the settlement cycle for a Turkey block trade?
The negotiated block is printed to Borsa İstanbul (BIST) 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 Turkey?
The principal threshold is 5%, under Disclosure of material holdings under the Capital Markets Law No. 6362 and the CMB communiques, overseen by CMB (SPK). 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 Borsa İstanbul (BIST); we manage cross-border custody, settlement and the disclosure that attaches to a substantial transfer.
10How quickly can a Turkey 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.

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