Mexico: Move to a T+1 settlement cycle approved by financial authorities


Clearstream Banking1 informs clients that on 12 April 2024, the National Banking and Securities Commission (CNBV) and Mexico’s central bank (BANXICO) have approved changing the settlement cycle for equity securities from two business days (T+2) to one business day (T+1). Effective

27 May 2024

Contraparte Central de Valores (CCV, Mexico’s equities CCP) will successfully conclude the regulatory modification process to reduce the ordinary settlement cycle of equity securities to one business day (T+1) as requested by the Asociación Mexicana de Instituciones Bursátiles (AMIB, Mexican association of brokerage firms).

CCV will publish the modifications to their internal bylaws and manual to formalise the change.

Which instruments are in scope of T+1? 

The scope of the move to T+1 settlement comprises Mexican equities and those listed in the international quotation system (SIC), which both consider the United States of America and Canada as their principal markets.

The CCP, in coordination with the AMIB and the financial authorities, will continue to work on the preparations for implementing the change and ensure a successful transition to T+1.
