Reserve ratio is the ratio of a bank's reserves to the amount of its demand deposits, i.e. its checking deposits. The Fed sets the required minimum ratio, currently 10%. Even with no specified minimum ratio, banks would have to maintain sufficient reserves to cover checks written by depositors and to provide cash on demand.
