TURKDEX extended the clearing period. Takasbank and TURKDEX had started the necessary analysis and software development work in 2005 and the settlement transactions with a T+1 value date in TURKDEX were started on March 20, 2006. As of that date, members have time to fulfill their margin requirements until 2.30 p.m. on the following day. There is no change with the pre-margining principle. Extending the settlement period from T+0 to T+1 improves interactions between TURKDEX transactions and other local spot markets and stock exchanges. It also ensures that foreign investor transactions are duly processed.
