City Bank has estimated that its average daily net transaction accounts balance over the recent 14-day computation period was $257 million. The average daily balance with the Fed over the 14-day maintenance period was $10 million, and the average daily balance of vault cash over the two-week computation period was $6 million. EXAMPLE 13-2 Computation of Daily Average Required Reserves Consider ABC Bank's reserve manager, who wants to assess the bank's minimum cash reserve requirement target. The manager knows the bank's net transaction accounts balance at the close of the banking day on each of the 14 days over the period Tuesday, June 30, to Monday, July 13.

The minimum daily average reserves that a bank must maintain is computed as a percentage of the daily average net transaction accounts held by the bank over the two-week computation period, where Friday's balances are carried over for Saturday and Sunday.
