I am not sure how much time one has to drain UR points after the account has been closed. I have always read T&Cs (not necessarily Chase's) that points/rewards require an account in good standing. I supposed banks might be required to give someone a grace period, especially if closure is not the individual's fault and without warning. I assumed you have already lost the points and was surprised how "calm" you are. I am glad you still have access to those points, but you probably shouldn't wait to move/redeem them unless there is a published policy that tells you how long you have after an account has been closed.
