Money Supply ProcessAgents

The CB influences the other players’ actions leading to changes inthe monetary aggregates, M, and the interest rates, i , by:

1 reserve requirements2 open market operations3 discount loans4 QE


Money Supply ProcessThe many forms of Money: from liquid to illiquid, M1, M2, M3

Central BankBalance Sheet

Liabilities• Currency in circulation: in the hands of the public• Reserves: bank deposits at the Fed and vault cash• Central Bank Securities• Government Deposits• Other



Assets• Government securities: holdings by the CB that a�ect money

supply and earn interest• Discount loans: provide reserves to banks and earn the

discount rate• Foreign Assets• Other



• The CB controls the Monetary Base (high-powered money:H):

H = CU + R

CU: Currency in circulation R: Total reserves in the bankingsystem.

• The CB has more control over the monetary base than overreserves through:

1 Open market operations2 Discount loans


Central BankCentral bank operations examples

• Discount Loans example• OM Purchase from a bank or a person (deposit and currency

cases) example: net e�ect on monetary liabilities is zero.Reserves are changed by random fluctuations. Monetary baseis a more stable variable.

• Interventions in the foreign exchange market:• Buying or selling foreign exchange.• Similar to a open market operation.• Usually sterilized, i.e. counteracted by operations that oset the

change in the monetary base.


Central BankTransmission: Deposit Creation

• By using its instruments, the CB controls the monetarybase/reserves and this translates to “control” of broadermonetary aggregates such as M1 by deposit creation by banks:

• OMP imply excess reserves increase; banks loan out the excessreserves; creates a checking account; borrower makespurchases; the money supply has increased

• If excess reserves are zero i.e. Required Reserves RR = TotalReserves TR

RR = ◊D◊=is the required reserve ratio and D= checkable deposits


Central BankTransmission: Deposit Creation

• Looking at changes:

�D =1◊�RR

1

◊ is the Simple deposit multiplier• Deposit creation continues until all excess reserves are

eliminated in the banking system.• Note that whether the banks chooses to use its excess

reserves to make loans or buy securities does not matter.


Central BankDeposit Creation

• A given level of reserves in the banking system determines thelevel of checkable deposits.

• By controlling reserves, the CB controls the level of checkabledeposits.

• By controlling checkable deposits, the CB controls the moneysupply (M1)

• Critique of the Simple Model:• Holding cash stops the process• Banks may not use all of their excess reserves to buy securities

or make loans


Money SupplyThe money multiplier

• Define money (M1) as currency plus checkable deposits or M= Cu + D

• The CB can control the monetary base better than it cancontrol reserve

• Link the money supply (M) to the monetary base (H) and letm be the money multiplier

M = mm ◊ H = mm ◊ (R + CU) = mm ◊ (RR + ER + CU)

mm tells us how much the money supply changes for a givenchange in the monetary base



• RR = ◊D

H = RR + ER + CU = ◊D + ER + CU

This reveals the amount of monetary base is needed tosupport the existing amounts of checkable deposits, excessreserves and currency

• An increase in H that goes into currency Cu is not multiplied,whereas an increase that goes into supporting deposits D ismultiplied

• An additional dollar of H that goes into excess reserves ERdoes not support any additional deposits or currency



• Assume the desired level of currency Cu grows proportionallywith the level of deposits D, i.e.

c =CUD

c is the currency ratio• Assume excess reserves ER grows proportionally with the level

of deposits D, i.e.ERD

e is the excess reserves ratio



H = R + CU = RR + ER + CU

RR = ◊D, where ◊ is the required reserve ratioER = e DCU = c D

H = RR + ER + CU = (◊ + e + c)D

we have the relation between the monetary base andthe level of deposits:

D =1

◊ + e + c H



Since money supply M equals deposits D plus currency C:

M =1 + c

◊ + e + c H

and the money multiplier is

mm =1 + c

◊ + e + c



mm =1 + c

◊ + e + c

• Changes in the required reserve ratio ◊. The money multiplierand the money supply are negatively related to ◊

• Changes in the currency ratio c. The money multiplier andthe money supply are negatively related to c

• Changes in the excess reserves ratio e. The money multiplierand the money supply are negatively related to the excessreserves ratio e



Figure : mm


Monetary PolicyInstruments

• the instability of the multiplier implies that M is di�cult touse as an instrument, especially mot illiquid part M2

• transmission of change in reserves to changes in M can beunstable

• reserve market allows to control the interest rate on reserves(opportunity cost of ER)

• transmission of the overnight interest rate to yield curve alsoproblematic but appear to work well in the short term paert ofthe curve


Monetary PolicyBorrowed and Non Borrowed Reserves

• Open market operations are controlled by the CB• The CB cannot determine the amount of borrowing by banks

from the CB• Split the monetary base into two components MBn = MB-BR

thereforeM = mm(MBn + BR)

• The money supply is positively related to both thenon-borrowed monetary base MBn and to the level ofborrowed reserves, BR, from the Fed

• In practice, the Fed generally sets the discount rate abovemarket interest rates such that BR is very small now intereston excesses reserves


Monetary PolicySupply and Demand in the Market for Reserves

• The supply of reserves can be broken up into two components:• the amount of reserves that are supplied by the CB’s open

market operations, called non-borrowed reserves• the amount of reserves borrowed from the CB, called discount

loans

• The primary cost of borrowing discount loans from the Fed isthe interest rate the Fed charges on these loans, the discountrate

Why is it important to control the overnight interest rate? For itstransmission to the longer maturity (analogy to liquidity in M1, M2and M3). The expectational hypothesis

where t is today, T is maturity and ie are expected interest rates.For example ie

t+1,1 is the one period expected interest rate in oneperiod.

Monetary PolicyTransmission to the real economy

• we are working in the background with a model in whichmonetary policy a�ects Aggregate Demand (AD) throughinterest rates management, at least for the short-medium run

• notice for AD it is the real interest rate that matters

r = i ≠ fi

• money growth rate translates into inflation in the long run• in models where AD is irrelevant (Flexible prices) money

growth a�ects inflation immediately


Monetary PolicyTransmission

Looking the best estimate – the purple line – we can see that increasing the interestrate leads to a reduction in output. In the euro area, the greatest decline in production isreached in the second and third quarters after the increase in the interest rate, comparedto five quarters in the USA.

The second panel from top shows the evolution of the price level. Remember that oneof the assumptions of the IS–LM model is that the price level is given, and thus does not vary with changes in demand. The figure shows that this assumption is not a bad representation of reality in the short term. In the euro area the price level remains almostunchanged approximately for the first five quarters (compared to two quarters in theUSA). It is only after the first five quarters that the price level begins to decline. This sug-gests that the IS–LM model becomes less reliable when we look at the medium term: inthe medium term we can no longer assume that the price level is given, and changes inprices become significant.

Comparing the euro area and the USA we observe that prices react more rapidly in theUSA, although the size of the responses are the same.

Figure 5.16 illustrates two important lessons:

1. It gives us a sense of the dynamics of adjustment in output and other variables inresponse to monetary policy.

2. It shows that what we observe in the economy is consistent with the implications of theIS–LM model. This does not prove that that model is the right model. It could also be that

Liquidity TrapNot the First Time

Figure :


Liquidity TrapIt can happen

• On December 16, 2008 the FOMC reduced the fed funds rateto nearly zero

• is monetary policy completely ie�ective at the zero lowerbound?

• unconventional policies refers to:• credible announcement of the future policy path (last

announcement: from mid 2014 to mid 2015 low fed funds)• changes in the composition and/or size of a central bank’s

balance sheet that are designed to ease liquidity and/or creditconditions


Balance Sheet ManagementChannels

• Expectations ⁄ Signalling Channel: captures those changes inthe expected path of future short-term rates (standardexpectation hypothesis)

QEAssessment: econometric study results

• The first LSAP programme (undertaken in 2009) consisted of$300 billion of Federal Reserve purchases ∆ 35bp (LT yields)corresponds to 140 bp in fed funds

• The second programme (in late 2010 to mid-2011) consistedof $600 billion of purchases ∆ 45bp (LT yields) correspondsto 180 bp in fed funds


QEUncertainty, controversy and international spillovers

• The QE e�ects are far from certain• They have costs: balance sheet reduction of the CB (?),

international spillovers...next class

Monetary PolicySummary

• The Central Bank Balance Sheet• By changing the amount of reserves CB can influence the

amount of Money• By changing the amount of reserves CB can target interbank

interest rate• CB can committ to a path of interest rates to influence the

yield curve• CB can use her balance sheet to target specific asset markets

such as LT bonds or Mortgages
