最佳解答:

1. Original B/S (assume lend out all excess reserves) Reserve $500 Deposit $1200 Loans $700 2. Withdraw $200 and immediately effect is deducted reserve Reserve $300 Deposit $1000 Loans $700 3. At day-end, Finance will adjust the reserve to meet reserve requirements (ie. RRR25%) new reserve = $1000x25%=$250 new excessed reserve = $300-250 = $50 would be placed in money market as leding (ie. Loans) Hence, Reserve $250 Deposit $1000 Loans $700 Placement $50 4. if new loans ($50) is granted to a customer, it would be deposit in customer account (as bank depsoit) The immediately result: Reserve $250 Depsoit $1050 Loans $750 Placement $50 5. at day-end, Finance would adjust the reserve & placement to meet reserve requirements The net result would be: Reserve $262.5 Depsoit $1050 Loans $750 Placement $37.5 That's why increase loan would increase money supply in the market. 6. If the customer draw down the loan (ie. take out cash from bank), it would be same as step 2.
