You can withdraw your CPFIS-OA and CPFIS-SA investments, as well as the cash balance in your Investment Account, after setting aside the Full Retirement Sum (FRS) in your Retirement Account (RA). The FRS can be set aside fully with cash, or with cash (i.e. at least the Basic Retirement Sum) and property.
Once your withdrawal application is approved, your CPFIS investments will be transferred to you. The withdrawal will not result in liquidation of your investment holdings.
