I did it last month. very simple just like you open FD in any bank. Since I already have e$aver, I just straight open the FD account. The customer service will fill in the form and get you sign then you will proceed to teller counter to deposit the money. The counter will give you a blue color type of FD slip/cert. On it written the initial period of FD rate. The renewal on the step-up is auto.

Now still available but on the safe side, call your nearest ocbc to confirm
