Q

Once financial institutions decide to grant a loan, they need to decide on the price thereof (i.e the interest rate)

Q

What are the 5 Factors that impact loan returns?

A

1) Base lending rate (prime lending rate – 7% can also be linked to JIBAR)
2) Fees relating to the loan
3) Credit risk premium (low credit score results in high-risk premium)
4) Collateral backing the loan
5. Compensating balance (% of loan that borrower must hold)

Q

Instead of the Base lending rate What rate was previously used globally? Why is it not used anymore?

A

LIBO
It is not used anymore because it was manipulated

Q

What is credit rationing?

A

It refers to how FIs group clients into categories of loan quantity restrictions rather than IR

In simple terms, Credit rationing is the bank refusing to issue the loan if too risky as opposed to just charging a higher interest rate

Q

23
Q

What interest rates are higher-risk borrowers charged?

A

Higher-risk borrowers are charged a risk premium

24
Q

At low rates what kind of risk do borrowers need to take?

Low or high risk

A

At low rates (k) borrowers do not need to take high risk and
can use FI funds.

25
Q

At high rates what kind of risk borrowers do need to take?

A

At high rates (k) borrowers may need to switch to high-risk
investment projects.

26
Q

What happens when IR rise above (k) (the contractually
promised loan
rate (k) percen)

A

When IR rise above (k) – the additional expected return earned by FI is offset by higher Probability of default

27
Q

Beyond a certain IR level, what must FIs do?

A

Beyond a certain IR level, FIs must credit ration their wholesale loans

28
Q

How can financial institutions measure Probability of default of clients?

A

by means of CVaR

29
Q

How can financial institutions measure credit risk at retail level?

A

They can gather information from credit agencies

30
Q

How can financial institutions measure credit risk at wholesale level?

A

use publicly available data e.g. stock prices, annual reports

31
Q

Will it be more costly for FIs to assess the default risk exposure of publicly traded companies or small, single proprietor firms?

A

small, single proprietor firms because they have less available data.

32
Q

List the 2 types of default risk models

A

Qualitative and quantitative measures

33
Q

How many factors do qualitative models Consider when making credit decisions

A

They consider 2 factors when making credit decisions

34
Q

List the 2 factors qualitative models Consider when making credit decisions

A

1) Borrower-specific factors
2) Market-specific factors

35
Q

What are Borrower-specific factors? (as a qualitative default risk model)

A

These are factors that are idiosyncratic (peculiar) to the individual borrower

36
Q

List 4 examples of Borrower-specific factors?

A

1) Reputation
2) leverage
3) volatility of earnings
4) collateral

37
Q

What are Market-specific factors?

A

These are factors that have an impact on all borrowers at time of decision

38
Q

List 2 examples of Market-specific factors?

A

1) Business cycle
2) interest rates

39
Q

How many types of Quantitative models? (as default risk models) exist?

A

There are 4 Quantitative models

40
Q

List the 4 Quantitative models? (as default risk models)

A

1) Credit Scoring Models
2) Logistic Regression
3) Multivariate Logistic Regression
4) RAROC models

41
Q

What are Credit Scoring Models? (as quantitative default risk models)

A

Here, observed borrower characteristics are used to calculate Probability of default or sort into a class

42
Q

What techniques are Credit Scoring Models based on ?

A

They are based on statistical pattern-recognition techniques

43
Q

What are the 4 things the Credit Scoring Model (as a quantitative default risk model) enable FIs to do?

A

This method enables FIs to:
1) Establish which factors are important in explaining default risk
2) Evaluate the degree of each factor’s importance
3) Improve the pricing of default
4) Better screen out bad loan applicants

44
Q

What is Logistic Regression? ( as a quantitative default risk model)

A

It is the most favoured in practice – almost no assumptions but for missing values and multicollinearity

45
Q

what are the benefits of logistic regression?

A

It is easy to compute and implement

46
Q

What is the goal of logistic regression?

A

It is to find the best fitting model to describe the relationship between one/more variables

47
Q

What is the Primary difference between linear regression and logistic regression?

A

It is the use of a
binary/dichotomous dependent variable (in logistic regression)

48
Q

Why can we not use a linear regression model as a default risk model ?

A

Since our main aim is to get a 1 or a 0, we cannot fit a straight line through the data, therefore we cannot use a linear regression model

49
Q

What is Multivariate Logistic Regression?

A

When there is more than one independent variable, we use multivariate logistic regression

50
Q

What are the 2 kinds of variables of Multivariate Logistic Regression

A

1) discreet variables
2) categorical variables

51
Q

What is a RAROC model?

A

Rather than evaluating ROA, with RAROC, the FI balances expected interest and fee income, less cost of funds, against the loan’s expected risk

52
Q

If using a RAROC model, when is a loan approved?

A

A Loan is only approved if RAROC is sufficiently high relative to benchmark (ROE)

Therefore, Loan should only be made if risk-adjusted return on loan adds to FIs equity as measured by ROE

53
Q

What is the numerator of the RAROC model?

A

The numerator is net income

54
Q

What is the denominator of the RAROC model?

A

The denominator is capital at risk since loan losses must be written off against FIs capital

A
