Title: Financial Crises
1Financial Crises
2Information inefficiencies
- Market participants can have insufficient
information about their counterparts (asymmetric
information). It leads to - Adverse selection. This is an information problem
occurring before the transactionPotential bad
credit risks are those who seek loans most
actively. - Moral hazard. This occurs after the trans-action
Borrowers may take on big risks.
3Elimination of asymmetric information (1)
- A first solution to the problem is the private
production and sale of information. - There are professional rating agencies (Standard
and Poors, Moodys, Value Line), and you can set
up costly monitoring and auditing (state
verification) of the firm. - But there is s free-rider problem to this. If
you buy a security, people my simply copy your
behavior without paying for the information. - This erodes potential extra profits, and you may
not have bought the information in the first
place.
4Elimination of asymmetric information (2)
- A second possibility could be to involve the
government in regulating the market. - The objective is to make firms reveal honest
information by adhering to standard accounting
practices and to disclose pertinent information. - Government can also impose stiff criminal
penalties to contain fraud. - Government regulation may ease the asymmetric
information problems, but it is difficult to
eliminate them totally.
5Elimination of asymmetric information (3)
- A third solution is to involve financial
intermediaries as experts in the production of
information. - A private loan is not traded, so others cannot
watch and imitate (no free rider). - This explains why indirect finance is more
important than direct finance. - Larger firms (because they are better known)
obtain easier access to capital markets than
smaller firms.
6Systemic instability and financial crises
- Financial crises are characterized by abrupt
declines in asset prices and by insolvencies of
financial and non-financial firms. - Such crises are reoccurring in many countries.
They are caused by a sharp increase in adverse
selection and moral hazard problems. - Four categories of factors trigger crises
- Increases in interest rates
- Increases in uncertainty
- Asset market effects on balance sheets and
- (Multiple) bank failures.
7Asset market effects on balance sheets
- Balance sheets have important repercussions on
the financial system - A deterioration (fall in stock or housing prices)
of the balance sheet reduces the net worth of a
firm. - Lenders are less willing to lend because of
reduced collateral. - This induces moral hazard because borrowers take
higher risks. - The increase in moral hazard makes lending less
attractive this reduces economic activity.

12Repercussions on the real economy
13Impact on peoples lives
- Top CEOs had a especially hard time !
14What dragged the economy down?
- The impact was then
- Increase of personal savings (and hence a
reduction of consumer spending) due to a
perceived reduction of personal wealth - Change in consumer behavior due to higher
unemployment - Credit implosion with an induced reduction of
demand, notably fixed investment - Reduction of housing investment due to prior
over-investment
15The Great Depression Further problems
- And
- A general loss in consumers and investors
confidence - Change in spending behavior due to insolvencies
and bankruptcies - Disintermediation due to a lack of liquidity
- Negative impact on public investment due to a
fall in tax revenue - Policy failures, e.g. strategic trade policies
(Smoot-Hawley Act)

17The central bank and systemic stability
- The health of the economy and the effectiveness
of monetary policy depend on a sound financial
system. Through supervising and regulating
financial institutions, the ECB is better able to
make policy decisions. - But should it intervene?
- Rescue failing banks?
18Lecture 6
- DETERMINANTS OF THE MONEY SUPPLY, AND THE TOOLS
OF CENTRAL BANKS, Part One
19European System of Central Banks
20European System of Central Banks
- The European System of Central Banks (ESCB)
consists of the European Central Bank (ECB) and
the national central banks of the EU Member
States. - The activities of the ESCB are carried out in
accordance with the Treaty establishing the
European Community (Treaty) and the Statute of
the European System of Central Banks and of the
European Central Bank (ESCB/ECB Statute).
21Governance of the ECB
- The ESCB is governed by the decision-making
bodies of the ECB. - The Governing Council of the ECB is responsible
for the formulation of monetary policy, - the Executive Board is empowered to implement
monetary policy. - The ECB has recourse to the national central
banks to carry out her operations. - The ESCB policy operations are executed on
uniform terms and conditions in all Member States.
22ESCB Basic tasks
- The basic tasks by the Eurosystem are
- to define and implement the monetary policy of
the euro area - to conduct foreign exchange operations
- to hold and manage the official foreign reserves
of the Member States and - to promote the smooth operation of payment
systems. - In addition, the Eurosystem contributes to the
prudential supervision of credit institutions and
the stability of the financial system.
23The US Federal Reserve System
- The formal structure of the Federal Reserve
System is characterized by - a regional decentralization (there are 12 Federal
Reserve Banks) - each Federal Reserve Bank is quasi-public (partly
held by government, partly by commercial banks in
the district). - all national banks chartered by the Office of the
Comptroller of the Currency have to be members of
the Federal Reserve System.
24The Federal Reserve Bank of New York
- The Federal Reserve Bank of New York has a
special role (through its involvement in the bond
and foreign exchange markets and through the
presence of large commercial banks). - The FRBNY is the only US Reserve Bank to be a
member of the Bank for International Settlements
(BIS). - Its president assumes a chief role in the system.
25Governance of the Federal Reserve System
- The Fed is headed by a seven-member Board of
Governors, with its influential Chairman (Alan
Greespan), headquartered in Washington D.C. - The Board of Governors is actively involved in
monetary policy making. - All governors are (voting) members of the Federal
Open Market Committee (FOMC). - In addition there are 12 (of whom 5 voting)
members from district banks in the FOMC.
26Should central banks be independent?
- A cornerstone of the monetary constitution of the
euro area is the independence of the ECB and of
the NCBs (Article 108). - There are fears that a dependent ECB
- could succumb to financing large budget deficits
of the government. - could be asked to monetize too much debt, which
would entails an inflationary bias. - Central banking also requires expertise and
should not be left to politicians.
27Should central banks be independent?
- Counterarguments
- It is undemocratic to have monetary policy
controlled by a non-elected elite group. - There is no accountability in central banking,
which is a precondition for, and core element of,
democratic legitimacy. - There is need to coordinate monetary and fiscal
policies. - The ECB could pursue a policy of self-interest.
28Principal-agent problem
- There is a typical principal-agent relation
between the Legislature and an independent
institution bestowed with a public function. - In line with the requirements of Article 113 of
the Treaty, the President of the ECB presents the
ECBs Annual Report to the European Parliament at
its plenary session. - This is followed by the adoption of a European
Parliament resolution, which provides a
comprehensive ex post assessment of the ECBs
activities and policy conduct. - The Chairman of the Fed reports to the US
Congress.
29The objectives of the ESCB
- The primary objective of the ESCB, as defined in
Article 105 of the Treaty, is to maintain price
stability. - Without prejudice to the primary objective, the
ESCB has to support the general economic policies
in the EU. - In pursuing its objectives, the ESCB has to act
in accordance with the principle of an open
market economy with free competition, favoring an
efficient allocation of resources.
30The mandates of central banks
31Reporting requirements of central banks
32ESCB monetary policy instruments
- In order to achieve its objectives, the ESCB has
at its disposal a set of monetary policy
instruments. - The ESCB
- conducts open market operations,
- offers standing facilities and
- requires credit institutions to hold minimum
reserves on accounts with the ESCB.
33Money supply process
- In order to understand the money supply process,
we have to come back to the ECBs balance sheet
and the monetary base (or high-powered money). - The assets of the CB constitute the sources of
the base. - The liabilities of the CB constitute the uses of
the base.

36The control of the monetary base
- The quantity-oriented approach to monetary policy
purports that the central bank can control the
monetary base. - It is basically effected via open market
operations with commercial banks. - The ECB can control OMOs more effectively than
foreign reserves, but she can also use
interventions in forex markets to change the
monetary base.
37Controlling the money supply
- Under fixed exchange rates controlling the money
supply is more difficult. - In this case the central bank has to sterilize
inflows or outflows of foreign exchange. - It renders interest rates endogenous, i.e. they
vary in response to sterilizing interventions. - Forex interventions will be discussed later.

39OMOs
- Among the OMOs, the main refinancing operations
(MROs) are the most important, playing a pivotal
role in steering liquidity and signaling the
stance of monetary policy. - Roughly 75 of liquidity is provided by MROs.
- MROs were conducted as fixed rate and variable
rate tenders with a minimum bid rate. - The MROs are regular, liquidity providing,
reverse transactions, conducted as standard
tenders, with a weekly frequency and normally a
maturity of two weeks.
40Longer-term refinancing (LTROs)
- Longer-term refinancing operations (LTROs) are
carried out through monthly standard tenders and
have a maturity of three months. - LTROs are regular open market operations executed
by the Eurosystem also in the form of a reverse
transaction. - On average over the year, LTROs provide about 25
of the total refinancing of banks.
41Reserve requirements of banks
- The Eurosystem requires banks to hold minimum
reserves equal to 2 of certain short-term
liabilities. It is part of base money. - The purpose is the stabilization of short-term
interest rates and the enlargement of the
structural liquidity deficit of banks. - Reserve requirements bear interest, and must only
be fulfilled on average over a one-month reserve
maintenance period. - It has a significant smoothing effect on the
behavior of short-term interest rates.
42Short-term liquidity policy
- The monetary base is also affected when a central
bank makes a discount loan to a bank. The ECB
does not use this instrument however. - There are two standing facilities offered by the
Eurosystem - the marginal lending facility and
- the deposit facility,
- These instruments provide and absorb overnight
liquidity, signal the stance of monetary policy
and set an upper and lower limit for the
overnight market interest rate.
43The use of the standing facility
44Key ECB interest rates
- The key ECB interest rates are at present
- the minimum bid rate on the main refinancing
operations, - the interest rate on the marginal lending
facility - and the interest rate on the deposit facility.
45What assets are eligible for credit operations?
46ECB interest rates
EONIA (euro overnight index average)
47Interest rate policy in Europe and the US
48The notion quantity of money
- In addition to the central bank, commercial banks
do also supply credit money. - We assume that there is a fixed
relationshipbetween central bank money (base
money) and credit money. - Then the quantity of money M equals M m ? B
multiplier ? base money. - We assume the ECB controls B, then she also
controls M.
49Money creation through bank credit
- Credit money is created (destroyed) if the sum of
demand deposits of non-banks at commercial banks
increases (declines) - In the case of a credit to a customer by a bank,
the bank creates book money. - As this credit is redeemed, money is destroyed.
50Money creation by a commercial bank
- Example A commercial bank receives a cash
deposit of 1 Mill. and uses it for a loan to a
firm of 1 Mill..
51Money creation by banks is it limited?
- Yes, money creation by banks is not infinite!
- Central banks require commercial banks to
maintain minimum reserves to be held on accounts
of the central bank. - These reserve requirements are calculated as a
percentage of demand, savings and time deposits. - Demand deposits represent a claim on central bank
money, which commercial banks cannot create
themselves.
52Multiple money creation An example
- Mr. K. puts 10,000 into his acount at A-Bank.
- The central bank requires minimum reserves of 20
of the deposit (?1/5). - There remains an excess reserve of 8,000.
- A-Bank grants a loan to Mr. L. for the purchase
of a car. The amount of the loan can only be
8,000.
53Example, continued
- Mr. L. transfers this amount to an account of the
car dealer at B-Bank. - At B-Bank it creates excess reserves of 8,000
minus 1,600 minimum reserves required (
6,400). - These excess reserves can be used for a loan,
etc.....
54Example, continued
- It is best to imagine this process in terms of
rounds of credit creation
55The money creation multiplier
- The money creation multiplier is obtained as a
result of an infinite geometric series. - In the example
- 10,000 8,000 6,400..... 50,000
- From an initial excess reserves of 10,000 an
an additional credit volume of 40000 can be
derived.
56The credit multiplier
- By subtracting R2 from R1 it is obtained1 -
(1-?) ? Cr 1-?1 - 1-??1 ER - ? ? Cr 1-? ER ? CrER (1-? / ? )
- or in this case (1-.2 / .2 ) 4
57Critique of the simple model
- Supply of credit must meet a demand!
- Banks do not extend their lending to the maximum
because of insolvency risks. - Lending is limited by capital adequacy ratios
(Basel I and II). - But there are refinancing possibilities
- through the ESCB, and
- through the interbank market.
58An example The Eurodollar market
- The Eurodollar market (better xeno market) is an
off-shore market for the US dollar (more
generally any hard currency). - It is characterized by the absence of mandatory
reserve requirements for commercial banks. - The experience has shown that this market had
avoided credit explosion.
