  1. chapter 15 Multiple Deposit Creation and the Money Supply Process

  2. Four Players in the Money Supply Process 1. Central bank: the Fed 2. Banks 3. Depositors 4. Borrowers from banks Federal Reserve System 1. Conducts monetary policy 2. Clears checks 3. Regulates banks

  3. The Monetary Base 1. MB = C + R = (Fed notes) + (bank deposits) + (Treasury currency) – (coin) Asset = Liabilities of Fed balance sheet  2. (Fed notes) + (bank deposits) = (securities) + (discount loans) + (gold and SDRs) + (coin) + (cash items in process of collection) + (other Fed assets) – (Treasury deposits) – (foreign and other deposits) – (deferred-availability cash items) – (other Fed liabs) Float = (cash items in process of collection) – (deferred-availability cash items) Substituting 2 into 1 and using definition of float: MB = (securities) + (discount loans) + (gold and SDRs) + (float) + (other Fed assets) + (Treasury currency) – (Treasury deposits) – (foreign and other deposits) – (other Fed liabs)

  4. Summary: Factors that Affect the Monetary Base

  5. Control of the Monetary Base MB = C + R Open Market Purchase from Bank The Banking System The Fed Assets Liabilities Assets Liabilities Securities – $100 Securities + $100 Reserves + $100 Reserves + $100 Open Market Purchase from Public Public The Fed Assets Liabilities Assets Liabilities Securities – $100 Securities + $100 Reserves + $100 Deposits + $100 Banking System Assets Liabilities Reserves Checkable Deposits + $100 + $100 Result:R $100, MB $100

  6. If Person Cashes Check Public The Fed Assets Liabilities Assets Liabilities Securities – $100 Securities + $100 Currency + $100 Currency + $100 Result: R unchanged, MB $100 Effect on MB certain, on R uncertain Shifts From Deposits into Currency Public The Fed Assets Liabilities Assets Liabilities Deposits – $100 Currency + $100 Currency + $100 Reserves – $100 Banking System Assets Liabilities Reserves – $100 Deposits – $100 Result: R $100, MB unchanged

  7. Discount Loans Banking System The Fed Assets Liabilities Assets Liabilities Reserves Discount Discount Reserves + $100 loan + $100 loan + $100 + $100 Result:R $100, MB $100 Conclusion: Fed has better ability to control MB than R

  8. Deposit Creation: Single Bank First National Bank Assets Liabilities Securities – $100 Reserves + $100 First National Bank Assets Liabilities Securities – $100 Deposits + $100 Reserves + $100 Loans + $100 First National Bank Assets Liabilities Securities – $100 Deposits + $100 Loans + $100

  9. Deposit Creation: Banking System Bank A Assets Liabilities Reserves + $100 Deposits + $100 Bank A Assets Liabilities Reserves + $10 Deposits + $100 Loans + $90 Bank B Assets Liabilities Reserves + $90 Deposits + $90 Bank B Assets Liabilities Reserves + $ 9 Deposits + $90 Loans + $81

  10. Deposit Creation

  11. Deposit Multiplier If Bank A buys securities with $90 check Bank A Assets Liabilities Reserves + $10 Deposits + $100 Securities + $90 Seller deposits $90 at Bank B and process is same Whether bank makes loans or buys securities, get same deposit expansion

  12. Deposit Multiplier Simple Deposit Multiplier 1 D = R rD Deriving the formula R = RR = rDD 1 D = R rD 1 D = R rD

  13. Banking System As a Whole Banking System Assets Liabilities Securities – $100 Deposits + $1000 Reserves + $100 Loans + $1000 Critique of Simple Model Deposit creation stops if: 1. Proceeds from loan kept in cash 2. Bank holds excess reserves
