Some reader share Maybank will disallow you to withdraw I think the last $10. So they slowly deduct $2 every month until he cannot take it go branch to close the account.I don't have SIF but for Maybank i savvy no need close. Just leave it open as $0 when not in use is ok right? Though my Maybank i leave $500. But my esaver i leave 0 for months. Only when needs arises such as this month then I'll use it again. Just make sure to only transfer in avoiding the fall below fee deduction hour. Can check at Maybank thread any issue for leaving as 0. So far for HSBC, Standchart, CIMB and RHB i have no problem in that.
