Thailand: Implementation of T+2 settlement cycle


Clearstream Bankingadvises customers that, effective

 2 March 2018

the Thai settlement cycle for all listed securities (scripless) trades will shorten from T+3 to T+2.

The change of settlement cycle has been a market-wide initiative spearheaded by the Stock Exchange of Thailand (SET) in order to meet international standards. The shortened settlement cycle is expected to reduce credit, market and liquidity risks and enhance efficiency of transactions.

Trading and settlement

The implementation date of the new settlement cycle in the Thai market is as follows:


Trade Date

Trade Day

Settlement Date

Settlement Day

Last T+3 trading day

28 February 2018


6 March 2018


First T+2 trading day

2 March 2018


6 March 2018


Note: 1 March 2018 is a public holiday in Thailand. Therefore, 6 March 2018 becomes the settlement date for both the last T+3 trading day and first T+2 trading day. In anticipation of a higher volume of securities settlements, the Bank of Thailand (BoT) is considering relaxing the daily ending balance for the NRBS account on that date.

Market participants, or clients of market participants, are expected to submit their settlement instructions by 09:00 Thai time / 03:00 CET on T+1 or SD-1 for further release into the pre-settlement matching system (PSMS) for auto-prematching before 12:00  Thai time / 06:00 CET on T+1 or SD-1.
