• For on-exchange trades, the settlement cycle is T+2, ensuring that transactions are settled two business days after the trade date. 
• For OTC trades, the settlement cycle is defined by participant instructions, providing flexibility based on individual needs. 
• We offer a custody model that includes give-up/take-up of settlement instructions, facilitating the smooth handling of securities transactions. 
• We partner with several banks for settlement, including Bank Center Credit JSC and Citibank Kazakhstan JSC.
