Ignore all those things that happened in previous questions. Start from the Base Case. You will see the application of this question in a later chapter. Bank A decides to have more Treasury bonds and fewer reserves. This is perhaps because the interest rates on Treasury bonds have increased. The bank buys $20,000 worth of bonds from a seller and pays for them by giving the seller a check for that amount. The seller is a member of the non-bank public. The seller deposits the check in Bank B. After all the interbank settlements and transfers, the entries in the two balance sheets will look like the following: Bank.A Bank B Total Deposits = Reserves = dollars Treasury Bonds = dollars Banking System (Bank A + Bank B) Total reserves in the banking system before Bank A's purchase of bonds = dollars Total reserves in the banking system after Bank A's purchase of bonds = dollars Ignore all those things that happened in previous questions.
