Vio Bank will typically place a hold on deposits for five business days, although some circumstances may necessitate a longer hold to ensure good funds and the safety of your account. During that period, you will see your deposit within Vio Online/Mobile Banking, but you won’t be able to transfer it out until the period ends. You will earn the full amount of interest for those days regardless of the length of the hold.
