Final answer:
When the Fed conducts an open market purchase, it affects Acme Bank's balance sheet by increasing reserves, decreasing bonds, and increasing loans.
Step-by-step explanation:
When the Fed conducts an open market purchase by buying $10 million in Treasury bonds from Acme Bank, it will result in changes to Acme Bank's balance sheet. The initial balance sheet consists of Assets - reserves of $30, bonds of $50, and loans of $50; and Liabilities - deposits of $100 and equity of $30. After the open market purchase, the balance sheet will change as follows:
- The reserves will increase by $10 million to $40 million.
- The bonds will decrease by $10 million to $40 million.
- The loans will increase by $10 million to $60 million.
- The deposits will remain the same at $100 million.
- The equity will remain the same at $30 million.
