Treasuries are purchased at a discount. Your leftover cash, along with interest payments, deposits, and maturity proceeds if chosen, all accrue in your Treasury Account. When the cash in your Treasury Account reaches $100, or enough to purchase another treasury,a new purchase will be completed automatically according to your Treasury Account allocation. Cash held in the Treasury Account cannot be invested and does not earn yield but it can be withdrawn. If you would like to withdraw cash from this account, you can follow the instructions here.
For further questions regarding cash in your Treasury account please contact Member Support via in-app chat or email at support@public.com.
