This MAS guidelines as below:
What are the requirements to open a fixed deposit account?
If you are an existing account holder, you will have to log in to the bank’s internet banking platform to open a fixed deposit. If you do not have an existing account with the bank, you might be required to open an account. This would require the following:
Front and back of your NRIC (for Singaporeans / PRs)
Passport and Employment Pass (for foreigners)
Proof of residential address
It is required due to ekyc purposes and Amla issue 🤦♀️
Unlike before OTC where you can open without savings and gone are those days anymore unless you are current existing renewal holders 🤦♀️
It same goes as Malaysian banks as they just want a placeholder account to fulfilled AmLa gathering of account holder details
Just to share more it is not mandatory actually. But those are to go to counter so when it mature you need go there to decide withdraw or renew. I done it before for a Spore finance company that comply with MAS regulations. But for online mobile where you never show face most if not all require some savings or current account and use that as source of funds to place FD. FD mature can go back to that account. If you manage to find one in Spore can online place FD and do no need open any savings or current account please share. Thanks.
