(LECTURA DE REFERENCIA: BHATTACHARYA Y THAKOR, 1993)
-
Why study Financial Markets and Institutions?
They are the cornerstones of the overall financial system in which financial managers operateIndividuals use both for investingCorporations and governments use both for financing
-
Overview of Financial Markets
Primary Markets versus Secondary MarketsMoney Markets versus Capital MarketsForeign Exchange Markets
-
Primary Markets versus Secondary Markets
Primary Marketsmarkets in which users of funds (e.g. corporations, governments) raise funds by issuing financial instruments (e.g. stocks and bonds)Secondary Marketsmarkets where financial instruments are traded among investors (e.g. Bolsa Madrid, NYSE, NASDAQ)
-
Money Markets versus Capital Markets
Money Marketsmarkets that trade debt securities with maturities of one year or less (e.g. Spanish Government bonds, U.S. Treasury bills)Capital Marketsmarkets that trade debt (bonds) and equity (stock) instruments with maturities of more than one year
-
Money Market Instruments Outstanding, 1990-1999 ($Bn)
-
Capital Market Instruments Outstanding, 1990-1999 ($Bn)
-
Foreign Exchange Markets
FX markets deal in trading one currency for another (e.g. dollar for yen)The spot FX transaction involves the immediate exchange of currencies at the current exchange rateThe forward FX transaction involves the exchange of currencies at a specified date in the future and at a specified exchange rate
-
Overview of Financial Institutions (FIs)
Institutions that perform the essential function of channeling funds from those with surplus funds to those with shortages of funds (e.g. banks, thrifts, insurance companies, securities firms and investment banks, finance companies, mutual funds, pension funds)
-
Flow of Funds in a World without FIs: Direct Transfer
Users of Funds
(Corporations)
Suppliers of Funds
(Households)

-
Regulation of Financial Institutions
FIs provide vital financial services to all sectors of the economy; therefore, their regulation is in the public interestIn an attempt to prevent their failure and the failure of financial markets overall
-
Globalization of Financial Markets and Institutions
Financial Markets became more global as the value of stocks traded in foreign markets soaredForeign bond markets have served as a major source of international capitalGlobalization also evident in the derivative securities market
-
Factors Leading to Significant Growth in Foreign Markets
The pool of savings from foreign investors has increasedInternational investors have turned to U.S. and other markets to expand their investment opportunitiesInformation on foreign investments and markets is now more accessible (e.g. internet)Some mutual funds allow ability to invest in foreign securities with low transaction costsDeregulation has enhanced globalization of capital flows

Tema 2
POR QU SON ESPECIALES LOS INTERMEDIARIOS BANCARIOS?
(LECTURA DE REFERENCIA: ALLEN Y SANTOMERO (1997)
-
Why Are Financial Intermediaries Special?
Objectives:Develop the tools needed to measure and manage the risks of FIs.Explain the special role of FIs in the financial system and the functions they provide.Explain why the various FIs receive special regulatory attention.Discuss what makes some FIs more special than others.
-
Without FIs
Corporations
(net borrowers)
-
FIs Specialness
Without FIs: Low level of fund flows.Information costs:Economies of scale reduce costs for FIs to screen and monitor borrowers Less liquiditySubstantial price risk
-
With FIs
-
Financial Structure Puzzles: a way to explain the role of FIs
stocks are not the most important source of external financing for businesses
issuing debt and equity is not the main way that businesses finance operations
indirect financing is more important than direct financing
banks are the most important source of external funds for businesses
financial industry is one of the most heavily regulated industries
only large, well-known firms have access to the securities markets
collateral is an important part of debt contracts for businesses and households
debt contracts are complex and often contain many restrictions for the borrower
-
Transaction Costs
information and other transaction costs in financial system can be substantial
How do transaction costs affect investing?
How can financial intermediaries reduce transaction costs?
-
Asymmetric Information
one party to a transaction has better information to make decisions than the other party
asymmetric information in financial market causes two main problems
adverse selection
moral hazard
-
Adverse Selection
asymmetric information problem that occurs prior to a transaction
examples of adverse selection
result of adverse selection is that lenders may decide not to make loans if they can not distinguish between good and bad credit risks
-
Moral Hazard
asymmetric information problem that occurs after a transaction
risk that borrower will undertake risky activities that will increase the probability of default
result of moral hazard is that lenders may decide not to make a loan
-
Lemons Problem
idea presented in article by George Akerlof in terms of lemons in used car market
used car buyers are unable to determine quality of car - good car or lemon?
What amount is buyer willing to pay for this used car of unknown quality?
How can buyer improve information on quality?
-
Lemons Problem in Stock and Bond Market
asymmetric information prevents investors from identifying good and bad firms
What price will these investors pay for stock?
Who has better information about the firm?
Which firms will come to the market for financing under these conditions?
-
Principal-Agent Problem
define the principal-agent problem
Who is the principal and who is the agent?
What problem does a separation of ownership and control cause?
How could we prevent principal-agent problem?
-
Solutions to Financing Puzzles
lemons or adverse selection problem tells why marketable securities are not the primary source of financing
situation is similar in corporate bond market
tells why stocks are not the most important source of external financing
-
More Solutions to Financial Structure Puzzles
importance of financial intermediaries explains importance of indirect financing
explains why banks are most important source of external financing
explains why markets are only available to large, well-known firms
-
Functions of FIs
Brokerage functionActing as an agent for investors:e.g. Merrill Lynch, Charles SchwabReduce costs through economies of scaleEncourages higher rate of savingsAsset transformer:Purchase primary securities by selling financial claims to householdsThese secondary securities often more marketable
-
Role of FIs in Cost Reduction
Information costs:Investors exposed to Agency CostsRole of FI as Delegated Monitor (Diamond, 1984)Shorter term debt contracts easier to monitor than bondsFI likely to have informational advantage

3. Bank competition
3.1. BANK COMPETITION
THE STRUCTURE-CONDUCT-PERFORMANACE (SCP) PARADIGM: Many empirical studies have considered concentration - mainly the Herfindahl-Hirschman Index (HHI) - as a proxy for bank market power following the Structure-Conduct-Performance (SCP) paradigm (Berger and Hannan, 1989; Hannan and Berger, 1991).
However, several contributions to the banking literature during the last two decades have cast doubt on the consistency and robustness of concentration as an indicator of market power (Berger, 1995; Rhoades, 1995; Jackson 1997; Hannan, 1997).
-
IO theory predicts a correspondence between the Lerner index (L) as the spread between prices (P) and marginal costs (C) divided by prices - and the HHI so that , where is a conjecture parameter showing the response of the industry output to changes to a unit output change by the firm, and is the industry price elasticity of demand. If =1 there is a monopoly solution while if =0, then a Bertrand solution holds with L=0.
Hence, the correspondence depends upon restrictive assumptions on the conjecture and demand elasticity parameters.
-
As contestability increases in a market, the reliability of the HHI as a measure of market power is significantly limited.
Therefore, changes in the stability of the banking sector as a consequence of industry restructuring or liberalization may cast doubt on the validity of the HHI as a dynamic measure of competition. Instability will also affect conjecture and elasticity parameter so that the relationship between market power and concentration becomes blurred.
-
Although the SCP hypothesis of a positive relationship between concentration and profits can be derived from oligopoly theory under these assumptions of different solutions to a Cournot model, it is not warranted under alternative models.
Some empirical studies have even tested and rejected the hypothesis of Cournot conduct in the banking industry (Roberts, 1984; Berg and Kim, 1994). Econometric developments have permitted the emergence of empirical papers from the so-called New Empirical Industrial Organization (NEIO) perspective, by directly estimating the parameters of a firm's behavioral equation and, in particular, marginal costs - to directly obtain indicators such as the Lerner Index (Schmalensee, 1989).
-
Although price to marginal costs indicators are not new from a theoretical standpoint, marginal costs have only been econometrically estimated during the last two decades. Applications to the banking industry as in Shaffer (1993), Ribon and Yosha (1999) or Maudos and Fernndez de Guevara (2004) have already shown that these price to marginal costs indicators are frequently uncorrelated with concentration ratios.
-
The definition of the mark-up and the Lerner index can be directly derived from a simplified market structure model (Bresnahan, 1989) where banking firms are supposed to produce a single good.
Assuming that banks behave as profit maximizers, the general expression for intermediate oligopolistic market structures with m banks operating in the market is expressed as:
-
where p is the price of the bank product; C(yj, wj) is a cost function defined for each bank j where yj is the quantity produced by firm j in the industry and wj represents the vector of prices of the factors of bank j. The parameter j expresses the degree of market power from perfectly competitive (j = 0) to monopolist (j = 1). This can be alternatively written as:
-
where the mark-up of price over marginal cost ([p C(yj, wj)]) equals the inverse of the semi-elasticity on bank product demand (1/) times the market structure parameter (j). Therefore, higher values of the mark-up measure will indicate a worsening of bank competition conditions either by a decrease in the semi-elasticity of demand on bank product () or an increase in the market structure parameter (j).
-
The mark-up is used to compute the Lerner index, which is a relative margin computed as [p C(yj, wj)] / p. Higher values of the Lerner index also indicate a worsening of competition conditions.
-
3.2. BANK EFFICIENCY: AN APPLICATION TO THE SPANISH CASE
Previous Cost Efficiency Results in Banking
The average bank experiences total (operating + interest) costs that are 20 to 25% higher than the most cost efficient bank.
This is the conclusion of many individual studies as well as the average result from 130 studies across 21 countries for 5 different frontier cost approaches.
Bank net income is from 15 to 20% of total costs. Thus the average bank could more than double its profits/ROA if it achieved frontier efficiency or "best practice".
Yet, cost efficiency seems relatively stable over time and
seemingly beyond the control of management.
-
Efforts to "explain" both the level of cost efficiency and its apparent stability over time have not be very successful.
Almost all explanatory analyses have so far focused on balance sheet "causes" or associations with measured inefficiency. Fixed effects models (dummy variables) do better but do not identify the causes.
The few studies that have looked at banks' external business environment have been more successful.
(Berger & Mester, 1997; Dietsch & Lozano Vivas, 2000)
-
NEW EVIDENCE: A three-part Approach to Cost Efficiency (a recent paper by Carbo, Humphrey and Lopez)
Explain efficiency differences using information on:
1. A bank's external business environment (following
Berger & Mester, 1997; Dietsch & Lozano Vivas, 2000);
2. A bank's technical ability to combine inputs into outputs
using a cost function specification--the standard approach;
3. A bank's internal productivity, using common peer group
indicators to decompose remaining measured inefficiency.
As expect operating cost to reflect most efficiency differences, we separate operating from interest costs.
-
Estimation Approach
Parametric Model (Cost Function):
Distribution-Free approach to efficiency measurement--assumes random errors estimated for each individual bank over 10 years averages to zero, leaving an unexplained "inefficiency" residual (Ui).
Bank with the smallest inefficiency residual (Umin) is on the cost frontier. Efficiency is measured as: EFF = Umin/Ui.
If Umin/Ui = .80, resources used at most efficient bank are only 80% of those used at bank i. Inefficiency at bank i is (1 - .8)/.8 = 25%.
-
Estimation Approach
Parametric Model (Cost Function):
As Fourier and translog cost functions give same initial results, report parametric results using the simpler translog cost model.
Non-Parametric Model (Linear Programming):
Data Envelopment Analysis (DEA) determines bank that produces a given output vector with minimum input cost.
As assume random error is zero, can determine EFF for each year.
-
Ensuring Comparability
Parametric Model: Distribution-Free approach represents average EFF over 10 years. Thus report DEA results as a 10-year average.
Non-Parametric Model: DEA approach does not truncate "extreme" EFF values. Thus report untruncated Distribution-Free results.
(Truncation raises efficiency values. Is used because assumption that error for each bank averages to zero is likely too strong to be met.)
-
Efficiency of Spanish Banks (Cost Function Only)
Average Efficiency Estimates: 1992-2001 (1,540 panel obs.)
Parametric EFF = 85%(18% unexplained inefficiency)
R2 = .995
| Ui |/total cost = 5%
Non-Parametric EFF = 87%(16% unexplained inefficiency)
Other Spain
82% (Lozano, Pastor, & Pastor, 2002)
Estimates:
87% (Maudos & Pastor, 2003)
-
Efficiency of Spanish Banks
Almost all efficiency studies stop here. Some go on to regress
EFF values on various balance sheet "influences".
Low R2s (e.g., .10) are the typical result, so actual causes of inefficiency remain largely unexplained.
Inefficiency usually attributed to typically unspecified:
Managerial policies & procedures
Organizational structure
Leadership ability

Results So Far
External, Technical, and Internal variables together explain
almost all bank cost efficiency differences for Spain.
Internal/productivity influences, not balance sheet variables,
identify source of cost inefficiency.
Parameter signs show that operating cost falls and efficiency
rises when:
Deliver services using more ATMs vs. branches;
Each branch generates more deposits with less labor.
(The "black box" was never black, just not fully specified.)
-
Results So Far
Earlier studies have found EFF to be relatively stable over time.
The DEA results of this new paper are also relatively stable by year (not shown).
Now look at time-series (mean) vs. cross-section (dispersion)
changes in unit operating cost (OC/TA).
Why? Because ATM/branch tradeoff and other productivity
indicators explain both cross-section OC efficiency differences
and the observed time-series reduction in OC.

What are Financial Intermediaries (FIs)?
Financial Securities: contingent claims on future cash flows debt, equity, derivatives, hybrids. All firms liabilities & net worth are predominately comprised of financial securities.But most firms hold real assets such as inventory, plant & equipment, buildings.FIs assets are predominately comprised of financial securities.

5.1. THE CONCEPT OF RISK
Risks facing all financial institutions can be segmented into three separable types, from a management perspective. These are:(i) risks that can be eliminated or avoided by simple business practices,(ii) risks that can be transferred to other participants, and,(iii) risks that must be actively managed at the firm level.
-
The management of the banking firm relies on a sequence of steps to implement a risk management system. These can be seen as containing the following four parts:(i) standards and reports,(ii) position limits or rules,(iii) investment guidelines or strategies,(iv) incentive contracts and compensation.
-
SOURCES OF RISK
For the sector as a whole, the risks can be broken into six generic types:
systematic or market risk
credit risk
counterparty risk
liquidity risk
operational risk
legal risk
-
Systematic risk is the risk of asset value change associated with systematic factors. It is sometimes referred to as market risk, which is in fact a somewhat imprecise term. By its nature, this risk can be hedged, but cannot be diversified completely away. In fact, systematic risk can be thought of as undiversifiable risk.
-
Credit risk arises from non-performance by a borrower. It may arise from either an inability or an unwillingness to perform in the pre-committed contracted manner. This can affect the lender holding the loan contract, as well as other lenders to the creditor.
Therefore, the financial condition of the borrower as well as the current value of any underlying collateral is of considerable interest to its bank
-
Counterparty risk comes from non-performance of a trading partner. The non-performance may arise from a counterparty's refusal to perform due to an adverse price movement caused by systematic factors, or from some other political or legal constraint that was not anticipated by the principals.
Diversification is the major tool for controlling nonsystematic counterparty risk.
-
Liquidity risk can best be described as the risk of a funding crisis. While some would include the need to plan for growth and unexpected expansion of credit, the risk here is seen more correctly as the potential for a funding crisis.
Such a situation would inevitably be associated with an unexpected event, such as a large charge off, loss of confidence, or a crisis of national proportion such as a currency crisis.
-
Operational risk is associated with the problems of accurately processing, settling, and taking or making delivery on trades in exchange for cash. It also arises in record keeping, processing system failures and compliance with various regulations.
As such, individual operating problems are small probability events for well-run organizations but they expose a firm to outcomes that may be quite costly.
-
Legal risks are endemic in financial contracting and are separate from the legal ramifications of credit, counterparty, and operational risks.
New statutes, tax legislation, court opinions and regulations can put formerly well-established transactions into contention even when all parties have previously performed adequately and are fully able to perform in the future.
-
5.2. REGULATION AND CREDIT RISK: AN EXAMPLE FROM BASEL II
Historically, regulation has limited who can:open or charter new banks and what products and services banks can offer.Imposing barriers to entry and restricting the types of activities banks can engage in clearly enhance safety and soundness, but also hinder competition.
-
It assumed that the markets for bank products, largely bank loans and deposits, could be protected and that other firms could not encroach upon these markets. Not surprisingly, investment banks, hybrid financial companies, insurance firms, and others found ways to provide the same products as banks across different geographic markets.
-
However, there is another type of regulation that has concentrated most of the attention in the last three decades, the bank capital regulation.Changes in reserve requirements directly affect the amount of legal required reserves and thus change the amount of money a bank can lend out. The main recent example is BASEL II.
-
THE STRATEGIC IMPACT OF BASEL II
Basel 2 is a step change in the regulation of capital adequacy. It will alter the industry frame of reference for banks in many ways: Regulators are clearly recognizing market realities and seeking a much closer congruence between regulatory and economic capital.
The new proposals are more complex and sophisticated than earlier schemes. They will also have to evolve as market conditions, technology and financial management techniques develop.
-
The calibration exercises that have resulted from the various Quantitative Impact Studies (QIS) are targeted (initially at least) to deliver broadly the same amount of capital as the current Accord. However, the mix of capital charges will change significantly with the wider range of risk weights and greater risk sensitivity of Basel 2.
Basel 2 will clearly be much more risk-sensitive in assigning capital charges. Mortgage lending and lending to higher quality borrowers will be incentivised under Basel 2.
-
It is not clear whether the present or new Basel Accord are a binding constraint on banks current credit operations. Jackson et al (2001, Bank of England WP) suggest that banks may employ more conservative capital standards than those imposed under Basel 1 or likely under Basel 2.
Compliance costs are likely to increase. Banks will have to evaluate (as a kind of capital investment decision) whether the costs (including compliance costs) of moving to the more advanced Basel 2 systems are worthwhile.
-
Banks will increasingly target better risk management as a source of competitive advantage. Increasingly, superior risk management will become a key success factor for those banks who are able to respond successfully to the new environment.
Nevertheless, specialist banks who focus on a smaller number of core products and services should similarly be able to obtain risk management benefits of specialization.
-
Basel 2 will enhance present securitisation trends in banking. This will help in its turn to emphasise further the strategic importance of investment banking. At the same time, lending bankers will face increasing adverse selection trends as the better credits are able to access directly the capital markets.
This trend will help to re-emphasise the importance of credit skills in lending banks. It will also put pressure on these banks to widen their margins (in order to achieve the higher risk premia needed to cover their more risky lending).
-
Governance will be an increasingly important issue in the new regime. More disclosure is not enough by itself to secure market discipline (the aim of Pillar 3). A wide collection of new and improved governance structures will be needed. These include:
a freer market in bank corporate control;good corporate governance in banks;incentive-compatible safety nets;no bail-out policies;and proper accounting standards.
Banks will be required to disclose more information than ever before to the external market. This will involve additional compliance costs. Strategically, it will reinforce any competitive advantage gained by good risk-management banks.
-
Under Pillar 3 and with likely changes in bank governance arrangements, the prospects of take-overs (and no bail-outs) for individual banks who are inefficient are likely to increase. This new world is a likely further threat to concepts like mutuality and subsidised (or at least protected from competition) regional banking.
Insofar as the new capital regime allows non-bank financial companies a competitive advantage (via lesser capital backing), banks will attempt to alter the balance of competitive advantage through regulatory arbitrage
-
More work is needed on stress testing under Basel 2 and banks can expect further, more detailed efforts from regulators in this area. Already, stress testing appears to be a standard management technique for many banks and most banks that stress test do so at a high frequency (daily or weekly): see Fender and Gibson (Risk, 2001).
-
Perhaps the most fundamental strategic impact of Basel 2 is that it will enhance the SWM (Shareholder Wealth Maximisation) model as the major strategic and managerial model for banks. The essence of this model is its focus on risk and return and the impact of this tradeoff on bank value; the model also emphasises the need for greater risk sensitivity in risk assessments and pricing. Within this model, better risk management is rewarded.
-
5.3. THE SPANISH SAVINGS BANKS AND THE NEW REGULATORY FRAMEWORK
Although most of the strategic implications mentioned earlier for retail banks apply also to Spanish savings banks, there are some specific features of the Spanish savings banks that may modify some of these conclusions. These specific features are explored in this section (and summarised in Diagram 1):
There have been some recent regulatory actions regarding risk and capital in the Spanish banking system that should be taken into account when defining the threats and opportunities of the new framework for savings banks. The development of a Default Hedging Statistical Fund (the so-called FECI) by the Bank of Spain are two of the recent developments in the regulatory field that impact on the current solvency risk of Spanish savings banks
-
The establishment of so-called statistical, pro-cyclical or dynamic provisions: Requiring banks to increase these provisions when the business cycle is positive and reducing them during downturns in order to favor intertemporal risk smoothing and loan supply.
Basel 2 does not appear to change the view of banking as a pro-cyclical business. Basel 2 could even exacerbate cyclical effects. It is this contingency that has led the Bank of Spain to establish the so-called pro-cyclical or dynamic provisions.
The recent lending patterns of the Spanish savings banks are known to reduce these pro-cyclical effects since they have increased credit supply almost linearly over the business cycle.
-
The lending behavior of savings banks has not resulted in higher defaults. On the contrary, default risk management at savings banks has apparently been more efficient than for commercial banks, a fact that may be largely explained by the intertemporal risk smoothing advantages achieved via a close contractual relationship with their customers.
-
There are three main types of savings-bank specific effects:
(1) those concerning the aim of Basel 2 and the differences between economic and regulatory capital;
(2) those that refer to specialization, size and lending diversification;
(3) those related to the implementation of the new capital adequacy requirements, including the sectoral project of Spanish savings banks for the global control of risk.
-
(i) Aim of Basel 2 and Economic and Regulatory Capital Differences
While the objective of Stakeholder Wealth Maximization (STWM) may match more closely the nature of Spanish savings banks, SWM should not be a problem for savings institutions since they have to compete with commercial banks. Nevertheless, the SWM model will be reinforced by Basel 2 and Spanish savings banks may benefit from recent regulatory changes that stress their ownership status as private and non-subsidised.
-
(ii)Size, specialisation and lending diversification
Specialist banks (like savings banks) focusing on a smaller number of core products may also be able to obtain the risk management benefits of specialisation. Continuous calibration and capital treatment may reduce the potential loss of competitiveness in retail banking. Servicing, relationship banking and dynamic lending will also be valued positively.
-
(iii) Final implementation of Basel 2 on Spanish savings banks: the sectoral project for the global control of risk
The Spanish Confederation of Savings Banks (CECA) has led an ambitious initiative to undertake a sectoral project for the global control of risk. Since this project is oriented to the whole savings bank sector, it has to deal with various problems, like the rigidities of employing a single model for all institutions.
However, the project is targetted to provide savings banks with adequate and centralised human and technological resources in order to implement their own model with a high standard of quality.
-
The model for each line of business incorporates risk measurement, control and management operating with three different working groups:
information management;
organization and procedures;
quantitative tools.
-
5.4. COMPARATIVE DESCRIPTIVE STATISTICS
The credit risk of Spanish depository institutions does not seem to be a concern in the short-run.
The ratios doubtful assets/total exposures and doubtful loans of other resident sectors/total exposures of resident sectors have decreased in recent years and are lower than 1% (Table 1).
Statistical provisions have increased over time as a percentage of total provisions (Table 1).
-
TABLE 1.
Source: Bank of Spain (Memory of Bank Supervision 2004)
-
Savings banks and credit co-operatives have enjoyed higher margins compared to commercial banks (Table 2). The margins are in line with the European standards.
However, competitive presures have resulted in a decrease of margins over time during the last years.
-
TABLE 2.

-
As shown in Table 3, Spanish banks have progressively changed their financial structure to fulfill the requirements of Basel 2.
Both Tier 1 and Tier 2 capital have increased significantly in recent years.
Banks have increased both the average weight of credit risk exposure and off-balance sheet exposure.
-
TABLE 3.
Source: Bank of Spain (Memory of Bank Supervision 2004)
-
Changes in capitalization structure have led to an anticipated fulfillment of Basel 2 requirements (Figure 1a).
Tier 1 capital has largely contributed to a reduction in capital requirements, in a context of a significant increase in risk-weighted assets (rise in overall business and Santanders purchase of Abbey National) (Figure 1b).
However, Tier 1 capital has contributed to the growth rate of capital (Figure 1c).
Reserves have contributed largely to the growth of Tier 1 capital while the contribution of intangible assets has been negative (Figure 1d).

Credit risk measurement has evolved dramatically over the last 20 years.The five forces made credit risk measurement become more important than ever before:
A worldwide structural increase in the number of bankruptcies.
A trend towards disintermediation by the highest quality and largest borrowers.
-
(iii) More competitive margins on loans.
(iv) A declining value of real assets in many markets.
(v) A dramatic growth of off-balance sheet instrument with inherent default risk exposure, including credit risk derivatives.
-
Responses of academics and practitioners:
Developing new and more sophisticated credit-scoring/early-warning systems
Moved away from only analyzing the credit risk of individual loans and securities towards developing measures of credit concentration risk
Developing new models to price credit risk (e.g. RAROC)
Developing models to measure better the credit risk of off-balance sheet instruments
-
Credit Risk Management
An FIs ability to evaluate information and control and monitor borrowers allows them to transform financial claims of household savers efficiently into claims issued to corporations, individuals, and governmentsAn FI accepts credit risk in exchange for a fair return sufficient to cover the cost of funding (e.g., covering the cost of borrowing, or issuing deposits)
-
Credit Scoring
Credit scoring system a mathematical model that uses observed loan applicants characteristics to calculate a score that represents the applicants probability of defaultPerfecting collateralensuring that collateral used to secure a loan is free and clear to the lender should the borrower defaultForeclosuretaking possession of the mortgaged property to satisfy a defaulting borrowers indebtedness Power of saletaking the proceedings of the forced sale of property to satisfy the indebtedness
-
Credit Scoring
Consumer (individual) and Small-business lendingtechniques for scoring consumer loans very similar to mortgage loan credit analysis but more emphasis placed on personal characteristics such as annual gross income and the TDS scoresmall-business loans more complicated and has required FIs to build more sophisticated scoring models combining computer-based financial analysis of borrower financial statements with behavioral analysis of the owner
-
Ratio Analysis

-
Large Commercial and Industrial Lending
Very attractive to FIs because transactions are often large enough make them very profitable even though spreads and fees are small in percentageFIs act as broker, dealer, and adviser in credit managementThe standard methods of analysis used for mid-market corporates applied to large corporate clients but with additional complicationsFinancial ratios such as the debt-equity ratio are usually key factors for corporate debt
-
The KMV Model
Banks can use the theory of option pricing to assess the credit risk of a corporate borrowerThe probability of default is positively related to:the volatility of the firms stockthe firms leverageA model developed by KMV corporation is being widely used by banks for this purpose
-
Calculating the Return on a Loan
A number of factors impact the promised return that an FI achieves on any given dollar loanthe interest rate on the loanany fees relating to the loanthe credit risk premium on the loanthe collateral backing the loanother nonprice terms (such as compensating balances and reserve requirements)
-
Return on Assets (ROA)
1 + k = 1 + f + (L + m)
1 - (b(1 - R))
where
k = the contractually promised gross return on the loan
f = direct fees, such as loan origination fee
L = base lending rate
m = risk premium
b = compensating balances
R = reserve requirement charge
-
Risk-Adjusted Return on Capital (RAROC)
Rather than evaluating the actual or promised annual cash flow on a loan as a percentage of the amount lent (ROA), the lending officer balances the loans expected income against the loans expected risk RAROC = One-year income on a loan/Loan (asset risk or capital at risk

ANATOMA DE LAS CRISIS BANCARIAS: LA CRISIS CREDITICIA DE 2007 Y 2008
(MATERIAL DEL PROFESOR)
-
Asymmetric information and its implications
Banking crises
Definition of a banking crisis.
Recent evidence and why we should care.
Sources of banking crises.
Regulatory responses
Strengthening regulation and supervision.
Reforming the financial safety net (deposit insurance and lender of last resort).
-
Asymmetric Informationand its Implications
-
Information is asymmetric when one party to an economic relationship or transaction has less information about it than the other party or parties.
Pervasive role in financial markets.
Lenders often do not know the riskiness of the borrower applying for a loan;
Lenders may not be able to observe whether the borrower will invest in a safe or risky project.
Definition
-
The very existence of financial institutions can be explained on asymmetric-information grounds.
Reason: financial intermediaries
specialize in gathering and analyzing infor-mation about borrowers and their investment projects.
They thereby attenuate the incidence of information asymmetries.
From this perspective, they act as delegated monitors.
-
Adverse selection. If the price of insurance against a particular contingency is fixed independently of the characteristics of the behavior of the insured, individuals at greater risk will choose to insure.
Moral hazard. After a contract comes into effect, insured agents have an incentive to change their behavior in ways that adversely affect the interests of the insurer.
General Implications
-
Free-rider problems. An agent that collects infor-mation about a particular risk may be unable to prevent other agents from using that information (e.g. deposit insurance institution that is unable to price risk accurately).
Rational herding. Agents may choose to disregard their own information and instead react to information on the decisions taken by other agents (information externalities).
-
Principal-agent and monitoring problems. A principal may be unable to observe perfectly the actions of the agent to whom a certain activity or responsibility is delegated. Examples:
Bank shareholders may not perfectly observe investment decisions taken by managers;
regulators may not be able to determine the exact degree of riskiness of loans made by banks.
-
Adverse selection ensures that a disproportionate number of bad projects are presented for financing.
Borrowers are induced to choose projects for which the probability of default is higher, because riskier projects are associated with higher expected returns.
May lead to credit rationing; see Stiglitz and Weiss (1981).
Banks may be tempted to engage in overly risky lending activities in the presence of deposit insurance.
Implications for the credit market

Banking Crises
-
Definition of a Banking Crisis
Problematic, no standard definition:
Example: (Detragiache, Demirguc-Kunt (1998a)).
A distress episode is a crisis when
Ratio of nonperforming loans to total bank loans exceeded 10%.
Cost of the rescue operation (or bailout) was at least 2% of GDP.
-
Episode involved a large-scale nationalization of banks (and possibly other institutions).
Extensive bank runs took place or emergency measures (deposit freezes, prolonged bank holidays, or generalized deposit guarantees) were enacted by the government.

Problems
Information on nonperforming loans: often not reliable and timely. Evergreening problem.
Cost of rescue operations is often difficult to measure due to the importance of quasi-fiscal costs, contingent liabilities, and restructuring costs.
Liquidity provided at below-market interest rates (quasi-fiscal effect).
Promise to bail out ailing banks provides an implicit subsidy.
-
Estimating the net costs of banking sector restructuring is difficult; requires assumptions about
amount of liquidity support;
present and future incidence of nonperforming loans and their recovery rate.
Estimates are often calculated on a gross basis; leads to overestimation by excluding (Hawkins and Turner (1999))
future proceeds from reprivatization;
loan recovery;
repayment of the liquidity assistance provided by the government.
-
Run or event criterion: A crisis can indeed, in some cases, be dated that way.
Problems
Runs are often short lived.
Dramaticevents rarely represent either the beginning, or the end, of the crisis.
In most cases insolvency problems were already present and worsening; event itself is merely the point at which underlying problems are revealed (either to the regulator or the public).

Subprime Mortgage Crisis
-
Background Introduction
What is Subprime lending? the practice of making loans to borrowers who do not qualify for the best market interest rate because of their deficient credit history or inability to prove they could for the loans they are applying.Subprime loan involves high risks.
--housing market
--a combination of high interest rates, bad credit history and murky financial situations associated with the applicants.
-
Causes of the Crisis
Many factors created the crisis, but the most immediate causes were a rising interest rate environment which caused people with adjustable rate mortgages (ARM) to see significant increases in their mortgage payments, and declining property values as the national real estate market finally began making corrections (Housing bubble bursts).
-
Role of Mortgage lenders
--Incomplete lending procedure. For example, Many of the sub-prime loans did not even require that borrowers document the income listed on their loan application with a pay stub. some of the lending probably involved actual fraudulence where people misstated their income and qualifications.
--adjustable-rate mortgages (ARM); interest-only adjustable-rate mortgages
-
Role of Subprime borrowershomeowners
--With the assumption that housing prices would continue to increase, many subprime borrowers are encouraged to obtain ARM.
--Difficult to refinance due to declining property values.
Role of Regulators
--In response to a concern that lending environment was too easy or say, not properly regulated, the House and Senate are both considering making some new bills to regulate lending practices.

Part III- The countrywide influence and the corresponding reactions
Drastic fluctuation in stock market--investors began to worry about whether the Subprime crisis will turn into a global economic one.Many investment banks, mortgage lenders, real estate investment trusts and hedge funds suffered significant losses as a result of mortgage payment defaults or mortgage asset devaluation.

Banking Crises: Regulatory Responses
Information disclosure.
Strengthening regulation and supervision.
Reforming the financial safety net (deposit insurance and lender of last resort).
-
Information disclosure
Transparency (e.g. improvements in standards for data dissemination): viewed as important to crisis prevention.
Can help markets to improve their pricing of risk, prevent the buildup of imbalances, and force policymakers to take timely action to address vulnerabilities.
However: information disclosure is not a cure-all. Information is noisy and can be misinterpreted; perverse effect: bank runs.
-
Strengthening regulation and supervision
Current consensus: bank supervision needs to be strengthened before financial liberalization.
Objectives: ensure adequate internal controls and procedures, avoid concentrated patterns of credit or market risk exposure...
enforce accounting principles and disclosure requirements...
impose stricter asset classification and provisioning practices that reduce the scope for delay in recognizing bad loans, and encourage banks to make adequate provisions against loan losses.
-
Also: improve incentives for supervisors. Risks of forbearance (leaving insolvent banks in operation) and regulatory capture: create moral hazard, regulation becomes ineffective.
October 1997: Basle Committee on Banking Supervision released 25 core principles for effective banking supervision that cover
licensing structure,
prudential regulations and requirements,
methods for on-site and off-site banking supervision,
information requirements,
prerogatives of supervisors.
-
Prudential regulations aimed at containing risks associated with capital flows:
Limits on banks open net foreign currency positions (difference between unhedged foreign-currency assets and liabilities).
Limits on exposure to volatility in equity and real-estate markets
would help to insulate the banking system from bubbles associated with large capital inflows
and help to avoid excessive concentration of credit risk.
-
Discourage excessive exposures of domestic firms and (indirectly banks) by taxing short-term capital inflows (e.g. Chile).
Impose marginal reserve requirements on deposits (higher as the maturity of deposits shortens); help to
insulate the banking system from exposure to the risks of abrupt reversals in capital flows;
prevent a credit boom driven by a surge in bank deposits (ensures a gradual expansion of banks' loan portfolios).
Attractive goal when capital inflows take mostly the form of short-term bank deposits.
-
Problems
measures could result in some degree of disintermediation of capital inflows;
they do not discriminate between weak (or undercapitalized) banks and strong banks, whose behavior is less risky and credit assessment capacity is strong.
