Introduction
Financial institutions provide a wide range of financial products and services. They serve as intermediaries between providers and recipients of capital, facilitate asset and risk management, and execute transactions involving cash, securities, and other financial assets.
Given the diversity of financial services, it is unsurprising that numerous types of financial institutions exist. Types of financial institutions include deposit-taking, loan-making institutions, investment banks, credit card companies, brokers, dealers, exchanges, clearing houses, depositories, investment managers, financial advisers, and insurance companies. In many situations, overlap of services exists across types of institutions. For example, banks not only take deposits and make loans but also may undertake investment management and other securities-related activities and may offer such products as derivatives, which are effectively insurance against adverse effects of movements in the interest rate, equity, and foreign currency markets.
Banks accept from consumers and businesses and pay interest in return. Banks invest those funds in or extend loans to companies and. When the interest a bank earns from loans exceeds the interest paid on deposits, it generates income from the. Banks also earn interest from investing cash in short-term securities and from fees charged for their products and services such as wealth management advice, checking account fees, overdraft fees, ATM fees, interest, and credit cards.
Analyzing a Bank: The Camels Approach
"CAMELS" is an acronym for the six components of a widely used bank rating approach originally developed in the United States. The six components are Capital adequacy, Asset quality, Management capabilities, Earnings sufficiency, Liquidity position, and Sensitivity to market risk.
A bank examiner using the CAMELS approach to evaluate a bank conducts an analysis and assigns a numerical rating of 1 through 5 to each component. A rating of 1 represents the best rating, showing the best practices in risk management and performance and generating the least concern for regulators. A rating of 5 is the worst rating, showing the poorest performance and risk management practices and generating the highest degree of regulatory concern. After the components are rated, a composite rating for the entire bank is constructed from the component ratings.
This is not a simple arithmetic mean of the six component ratings: Each component is weighted by the examiner performing the study. The examiner's judgment will affect the weighting accorded to each component's rating. Two examiners could evaluate the same bank on a CAMELS basis and even assign the same ratings to each component and yet arrive at different composite ratings for the entire bank.
Although the CAMELS system was developed as a tool for bank examiners, it provides a useful framework for other purposes, such as equity or debt investment analysis of banks. The following sections discuss each component of the rating system.
Capital Adequacy
It is important for a bank (as with any company) to have adequate capital so that potential losses can be absorbed without causing the bank to become financially weak or even insolvent. Losses reduce the amount of a bank's retained earnings, which is one component of capital. Large enough losses could even result in insolvency. A strong capital position lowers the probability of insolvency and bolsters public confidence in the bank.
Capital adequacy for banks is described in terms of the proportion of the bank's assets funded with capital. For purposes of determining capital adequacy, a bank's assets are adjusted based on their risk, with riskier assets requiring a higher weighting. The risk weightings are specified by individual countries' regulators, and these regulators typically take Basel III into consideration. The risk adjustment results in an amount for risk-weighted assets to use when determining the amount of capital required to fund those assets. For example, cash has a risk weighting of zero, so cash is not included in the risk-weighted assets. As a result, no capital is required to fund cash.
Corporate loans have a risk weighting of 100%, and certain risky assets. Impact on P/B: The Price-to-Book (P/B) ratio compares a bank's market value to its book value (shareholders' equity). A higher capital adequacy rating often leads to a higher P/B ratio because investors are willing to pay a premium for a bank that appears financially stable and less risky.
Strong capital buffers suggest the bank is better equipped to weather downturns, which makes it more attractive to investors.
- Capital Requirements: Under Basel III, banks are required to maintain a higher quality of capital, particularly Common Equity Tier 1 (CET1) capital. The CBE has adopted these requirements, setting a minimum CET1 ratio and Total Capital Ratio, ensuring banks have enough cushion to absorb losses.
- Capital Conservation Buffer (CCB): The CBE mandates a capital conservation buffer on top of the minimum capital requirement. This buffer helps banks maintain a capital cushion in times of economic stress.
- Counter-Cyclical Capital Buffer (CCyB): The CBE has also implemented the counter-cyclical capital buffer to be applied in times of excessive credit growth, although its use is contingent on the economic environment.
Asset Quality
Asset quality pertains to the amount of existing and potential credit risk associated with a bank's assets, focusing primarily on financial assets. The concept of asset quality extends beyond the composition of a bank's assets and encompasses the strength of the overall risk management processes by which the assets are generated and managed. Loans typically constitute the largest portion of a bank's assets. Asset quality for loans reported on the balance sheet depends on the creditworthiness of the borrowers and the corresponding adequacy of adjustments for expected loan losses. Loans are measured at amortized cost and are shown on the balance sheet net of allowances for loan losses.
Impact on ROE: The Return on Equity (ROE) measures how efficiently a bank generates profits from its equity capital. If a bank has high asset quality and manages NPLs well, it will likely experience lower provisioning for loan losses and higher profitability, boosting its ROE. In contrast, a bank with poor asset quality may have a lower ROE because it needs to allocate more capital to cover potential loan defaults, thereby reducing net income.
Management Capabilities
Many of the attributes of effective management of financial institutions are the same as those for other types of entities. Effective management involves successfully identifying and exploiting appropriate profit opportunities while simultaneously managing risk.
For financial institutions, a particularly important aspect of management capability is the ability to identify and control risk, including credit risk, market risk, operating risk, legal risk, and other risks. Directors of banks set overall guidance on risk exposure levels and appropriate implementation policies and provide oversight of bank management. Banks' senior managers must develop and implement effective procedures for measuring and monitoring risks consistent with that guidance. The CBE requires banks to implement robust risk management frameworks in line with Basel III principles, covering credit, market, and operational risks.
Resolution Planning and Recovery Framework Following Basel III guidelines, the CBE has implemented rules requiring banks to develop recovery and resolution plans. These plans outline how banks can recover from financial stress or be orderly resolved without threatening the broader financial system.
Impact on ROE: Strong management leads to better strategic decisions that can improve profitability. A well-run bank is likely to generate higher returns on equity as it efficiently allocates resources, manages risks, and controls operational costs.
Earnings
Financial institutions should ideally generate an amount of earnings to provide an adequate return on capital to their capital providers and specifically to reward their stockholders through capital appreciation and/or distribution of the earnings. Further, all companies' earnings should ideally be high quality and trending upward. In general, high-quality earnings mean that accounting estimates are unbiased and the earnings are derived from sustainable rather than non-recurring items. For banks, one important area involving significant estimates is loan impairment allowances. In estimating losses on the loan portfolio collectively, statistical analysis of historical loan losses can provide a basis for an estimation, but statistical analysis based on past data must be supplemented with management judgement about the potential for deviation in future. In estimating losses on individual loans, assessments are required concerning the likelihood of the borrower's default or bankruptcy and the value of any collateral.
Many of the factors have a high degree of interdependency and there is no single factor to which our loan impairment allowances as a whole are sensitive."20 Banks also must use estimates in valuing some financial assets and liabilities that must be measured at fair value. When fair value of an investment is based on observable market prices, valuation requires little judgment. However, when fair values cannot be based on observable market prices, judgment is required. Under both IFRS and US GAAP, fair value measurements of financial assets and liabilities are categorized on the basis of the type of inputs used to establish the fair value. Both sets of standards use the concept of a fair value hierarchy.
