CIMB TT to MY is instant. You can see the MYR funds immediately.
If you transfer before the daily cutoff time, the funds will be for value in your receiving account 1 day after you transfer. OCBC and Citi can see on the afternoon or evening of T+1. For banks like DBS, UOB and CIMB, you only see it on T+2 working days but shown as value on T+1.
