Formed in 2013 from the consolidation of the Istanbul exchanges, bridging European and Middle Eastern capital. Single-stock turnover is high; lira volatility is the central structuring consideration for a TRY-denominated pledge.
On Borsa İstanbul, a block is placed through the Wholesale Market, which is built for equity lots above a set size traded to identified or unidentified counterparties away from the order book. The names that clear a block cleanly are the BIST 30 and larger BIST 100 constituents, where single-stock turnover is deep; outside the large caps, depth thins and the print is priced to it. Settlement runs T+2 through Takasbank, and any resulting move across a Capital Markets Law threshold is notified through the Central Registry Agency.

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.
