π Topic Summary: Commercial Bank Balance Sheets for AP Macro
Understanding a commercial bank's balance sheet is fundamental for AP Macroeconomics. It's a snapshot of a bank's financial health at a specific point in time, organized into two main categories: Assets and Liabilities plus Owner's Equity. The core principle is that total assets must always equal total liabilities plus owner's equity ($Assets = Liabilities + Owner's Equity$).
On the Asset side, you'll find what the bank owns or is owed, such as reserves (cash held by the bank or at the Federal Reserve), loans issued to customers, and securities (investments). On the Liability side, you'll find what the bank owes to others, primarily customer deposits (like checking accounts) and borrowed funds. Owner's equity represents the ownership stake. Banks play a crucial role in money creation by lending out their excess reserves, thereby increasing the money supply in the economy.

βοΈ Part B: Fill in the Blanks
Complete the paragraph below using the following terms: assets, liabilities, required reserves, excess reserves, loans, money supply.
When a customer deposits $1,000 into their checking account, this increases the bank's cash holdings (an __________ ) and also increases its demand deposits (a __________ ). If the reserve ratio is 10%, the bank must hold $100 as __________. The remaining $900 becomes __________, which the bank can then use to make new __________. This lending process ultimately contributes to an increase in the overall __________ in the economy.
π€ Part C: Critical Thinking
Imagine the Federal Reserve suddenly decreases the required reserve ratio from 10% to 5%. What immediate impact would this have on commercial banks' ability to lend, and what would be the broader effect on the economy's money supply? Explain your reasoning. π‘
