Final answer:
The correct sequence of events after the Fed buys securities from a bank is that the bank's reserves and money supply increase, interest rates fall, and the bank's lending capacity increases. The final answer is option C.
Step-by-step explanation:
When the Federal Reserve (the Fed) buys securities from a bank, we can expect a specific sequence of events affecting the banking system and the economy.
- The bank's reserves increase because the Fed pays the bank for the securities, placing money into the bank's reserve account.
- The money supply increases, as the bank now has extra reserves to back new loans and the currency paid by the Fed circulates in the economy.
- Interest rates fall because with more money available, the price of borrowing—that is, the interest rate—tends to go down due to lesser scarcity of funds.
- The bank's lending capacity increases because increased reserves mean the bank can issue more loans.
Therefore, the correct sequence starting with the Fed buying securities from a bank is: Bank's reserves increase, money supply increases, interest rates fall, and bank's lending capacity increases. The final answer to the sequence question is C.
