Copyright  2011 Pearson Canada Inc Monetary Base MB = C + R – MB: monetary base (high-powered money) –C: currency in circulation (notes and coins held by the public outside banks) –R: total reserves in the banking system (vault cash + settlement balances) The Bank of Canada controls the monetary base through open market operations and advances to banks

If reserves increase by $100, chequable deposits rise to $1000 in order for total desired reserves to also increase by $100

Copyright  2011 Pearson Canada Inc Factors that Determine the Money Supply II Changes in the Desired Reserve Ratio, r –The money supply is negatively related to the desired reserve ratio Changes in Currency Holdings –The money supply is negatively related to the currency holdings

Copyright  2011 Pearson Canada Inc The Money Multiplier Define money as currency plus chequable deposits: M1+ The Bank of Canada can control the monetary base better than it can control reserves Link the money supply (M) to the monetary base (MB) and let m be the money multiplier M = m x MB

Copyright  2011 Pearson Canada Inc Deriving the Money Multiplier I Assume the desired level of currency (C) and desired reserves (DR) grows proportionately with chequable deposits (D) Then: c = (C/D) = currency ratio r = (DR/D) = desired reserve ratio

Copyright  2011 Pearson Canada Inc Deriving the Money Multiplier II The total amount of reserves (R) equals the sum of desired reserves (DR). Assume excess reserves are zero at the equilibrium. R = DR The total amount of desired reserves equals the desired reserve ratio times the amount of chequable deposits DR = r x D Substituting for DR R = (r x D) The banks set r to be less than 1

Copyright  2011 Pearson Canada Inc Deriving the Money Multiplier III The monetary base (MB) equals currency (C) plus reserves (R) MB = R + C = (r x D) + C Shows the monetary base needed to support existing amounts of D and C An increase in MB going into C is not multiplied, but an increase in MB going into D is multiplied

Copyright  2011 Pearson Canada Inc The Money Multiplier in Terms of the Currency Ratio MB = (c x D) + (r x D) = (c + r) x D D = 1/(c+r) x MB M = C + D M = (c x D) + D = (1 + c)D M = (1+c)/(c+r) x MB m= (1+c)/(c+r) While there is a multiple expansion of deposits, there is no such expansion for currency
