Couldn’t find much information online and I had asked customer service as of 1st April 2021. According to them, there’ll be 36 months grace period so as long as we have transactions once in a while it’ll be enough to keep the account active. Personally I’m also only using it once in a quarter so it should be fine. Hope this help! Pasting the information from CIMB Customer Service below: “We wish to inform that an account will turn into inactive status when there are no deposits or withdrawals performed by the account holder. Savings account will turned inactive after 36 months. Please be assured that your funds are still in the account and will continue to earn interest. You will not be able to transfer funds via internet banking or withdraw funds from ATM card (if applicable). The simplest method to activate the account will be to transfer any amount from your other bank’s internet banking to your CIMB Account. Upon receiving your transfer, your account will be activated the following day. There are no fees for inactive account.”
