# Basel Committee on Banking Supervision

Capital Markets Assignment

Question 1a (1/2 page): Outline the purpose of the Basel Committee on Banking Supervision (Basel Committee).

Question 1b (1 page): In December 2010, the Basel Committee on Banking Supervision (Basel Committee) released a package of reforms to raise the level and quality of regulatory capital in the global banking system (Basel III). Please describe the rationale for these changes and summarise key measures proposed as part of Basel III, including a summary of the three Pillars approach to capital management for banks.

Question 2a (3/4 page): Using APS 113 and other sources, clearly state and compare the credit risk weightings on residential mortgage loans and margin loans using an example of a \$600,000 home loan and \$600,000 margin loan which each currently have 60% loan-to-valuations ratios (LVR’s). The margin loan has a maximum LVR of 80%. State any assumptions. Explain your answer using references and present your numerical example in a table.

Question 2b (3/4 page): Based on the credit risk weightings you found in the previous question, would you expect the home loan or the margin loan to have a higher interest rate? Does this reflect actual interest rates in the market (quote your sources)? If not, what may be the reason for the difference?

Question 3: Using the attached spreadsheet and APRA’s Prudential Standard APS 112 (APS 112):

Question 3a (in spreadsheet): Calculate and enter the correct Credit Risk Weighted Assets into the grey cells for Bank A and Bank B in Table 3a for both on-balance sheet and off-balance sheet activities.

Question 3b (in spreadsheet): Use the calculated data and other information for Banks A & B in table 3a to enter the correct calculations into the grey cells in table 3b.

Question 3c (1/4 page): Make one suitable graph of the banks’ Credit Risk Weighted Assets which can be used to compare their risk profiles. Choose the axis units such as \$ or % and graph type such as column, pie or scatterplot which is most useful.

Question 3d (3/4 page): Comment on and compare the two banks’ different risk profiles and ability to absorb losses.

Question 4a (1/4 page): Summarise the Basel Committee on Banking Supervision Pillar 3 disclosure requirements for banks, including the purpose of these requirements.

Question 4b (1/2 page): Read the Pillar 3 disclosures for Macquarie Bank (MBL) and Bendigo and Adelaide Bank (BEN). Outline what is meant by impaired loans and facilities and compare impairment levels between BEN and MBL.

Question 4c (1/4 page): For BEN’s residential mortgage loan portfolio, estimate the average loan-to-valuation ratio (LVR) and other characteristics of the loans. State your assumptions.

Question 4d (1/2 page): In respect to Capital Adequacy for Australian ADIs, compare and contrast the Standardised Approach to Credit Risk and the Internal Ratings-based Approach to Credit Risk.

Question 4e (1/4 page): On page 19 of MBL’s disclosures, why are some of MBL’s residential mortgage exposures classified under the Internal Ratings Based (IRB) approach while others are classified under the Standardised approach?

Question 4f (1/4 page): On page 19 in MBL’s APS 330 Table 7(b), what is the ‘off-balance sheet’ and ‘non-market related’ component of residential mortgages? Be specific and give examples.

Question 1a (1/2 page): Outline the purpose of the Basel Committee on Banking Supervision (Basel Committee).

Answer The Basel Committee on Banking Supervision, popularly known as the Basel Committee was established in Basel, Switzerland in 1974 through the initiative of central banks of around ten countries which include Australia. The purpose of this committee is to provide for discussion on banking regulatory and supervision related issues such that the banking industry is streamlined and safeguarded, especially interests of the stakeholders including public (BCBC, 2017).

Hence, in other words, the committee discusses issues and provides guidelines that help to ensure quality of supervision and regulations in the banking industry worldwide. Further, the committee aims at streamlining the banking in various countries so as to get all of them at a common standard.

Some of the most well-known works of the committee include the capital adequacy and effective banking supervision (Basel, 2011).

Various teams within the committee include Standards Implementation Group, Policy Development Group, Accounting Task Force and Basel Consultative Group.

An important point to be noted is that the standards issued by the committee are not compulsory to adopt. However, the countries can do so voluntarily. At the same time, adopting Basel standards provides added credibility as it ensures adherence to common standards and practices.

Question 1b (1 page): In December 2010, the Basel Committee on Banking Supervision (Basel Committee) released a package of reforms to raise the level and quality of regulatory capital in the global banking system (Basel III). Please describe the rationale for these changes and summarize key measures proposed as part of Basel III, including a summary of the three Pillars approach to capital management for banks.

Answer Basel III is a voluntary framework provided by the Basel Committee around 2010 and it relates mainly to capital adequacy, stress testing and market liquidity risk. Basel III was particularly introduced to tackle the deficiencies in the banking regulation system as were observed during the financial crisis of 2007-2008. Hence, Basel III focuses on increasing liquidity and reducing leverage of the banks so as to ensure better regulation and strength in the financial systems. One of the key areas of focus in Basel III is the minimum capital ratios of the banks. The implementation of Basel III was supposed to be completed during 2013 but the same has been extended twice to 2018 and 2019 (BCBS, 2010).

The three main pillars that are there in Basel III are (BIS 2017):

1. Minimum Capital Requirements: This pillar deals with the total risk of the bank, particularly credit risk, market risk and operational risk. The minimum common equity ratio to be maintained by the banks is 4.5% and is calculated as CET1/RWAs. The minimum Tier 1 capital now stands at 6%. In addition, Basel III provides for cushion through capital conservation buffer (2.5% of RWAs) and a discretionary counter cyclical buffer (additional capital buffer during high credit periods and ranges from 0-2.5% of RWAs)
2. Supervisory Review: This pillar deals with ensuring that the banks have enough capital at all the times.
3. Market Discipline: This pillar deals with ensuring fairness and transparency of the procedures of the bank, such as, disclosing capital structure (both tier I and tier II capital) and capital adequacy.

In addition to the concepts in Basel II, Basel III introduced some new concepts, such as:

1. Minimum leverage ratio: It is calculated as Tier 1 Capital divided by total exposure of a bank (balance sheet and non-balance sheet). This needs to be maintained at a minimum level of 3%.
2. Liquidity Coverage Ratio: The ratio is calculated as High quality liquid assets divided by total net liquidity outflows over 30 days and is needed to be greater than 100%. The ratio ensures that the bank is able to meet its outflows through high quality liquid assets at a point of time.

Question 4e (1/4 page): On page 19 of MBL’s disclosures, why are some of MBL’s residential mortgage exposures classified under the Internal Ratings Based (IRB) approach while others are classified under the Standardized approach?

The IRB approach relies on a bank’s own rating and assessment system and this can be used only by banks meeting certain conditions, disclosure requirements and approval at national level.

The standardized approach relies on external ratings as provided by various credit rating agencies and the ratings are used to assess a bank’s credit risk.
