Basel Norms and Capital Adequacy: Pillars and Ratios — GK24 title card

Basel norms are the international rules that decide how much capital a bank must hold against the risks it carries. They matter to an aspirant for two reasons: banking examinations ask them directly in every cycle, and they explain why a bank can lend only a multiple of its own capital. The norms are issued by the Basel Committee on Banking Supervision, and the Reserve Bank of India then prescribes them for Indian banks, usually at a level stricter than the global minimum. This note covers the three generations of the norms, the composition of bank capital, the Indian ratios and the related frameworks an examiner may attach to the topic.

Who issues the Basel norms

The Basel Committee on Banking Supervision was set up in 1974 by the central bank governors of the Group of Ten countries, after the collapse of the German bank Bankhaus Herstatt exposed how a failure in one country could spread through the settlement system. The committee has its secretariat at the Bank for International Settlements in Basel, Switzerland, which is why the standards carry the city's name. The Bank for International Settlements itself was established in 1930 and is the oldest international financial institution in the world. The committee has no treaty power: its standards are recommendations, and they bind banks only when a national regulator such as the Reserve Bank of India adopts them.

Basel I, Basel II and Basel III

AccordYear issuedMain content
Basel I1988Credit risk only; a minimum capital to risk weighted assets ratio of eight per cent, with risk weights of zero, twenty, fifty and a hundred per cent
Basel II2004The three pillars; capital charges extended to market risk and operational risk
Basel III2010Better quality capital, capital buffers, a leverage ratio and liquidity standards, after the global financial crisis of 2008

Basel II rests on three pillars, and naming them in order is a standard question. Pillar one is the minimum capital requirement, covering credit risk, market risk and operational risk. Pillar two is the supervisory review process, under which the regulator may demand capital above the minimum if a bank's risks warrant it. Pillar three is market discipline, achieved through disclosure, so that depositors and investors can judge a bank for themselves. India adopted Basel I in 1992 and moved all commercial banks to Basel II by March 2009.

What counts as capital

Capital is graded by how well it absorbs losses. Tier one capital is going concern capital, which absorbs losses while the bank is still trading. Within it, Common Equity Tier one is the purest form: paid up equity capital, share premium, statutory reserves and retained earnings. Additional Tier one consists of perpetual instruments such as perpetual non cumulative preference shares and perpetual bonds. Tier two capital is gone concern capital, which protects depositors only in liquidation, and it includes revaluation reserves, general provisions, subordinated debt and hybrid instruments.

The ratio built from these is the capital to risk weighted assets ratio, usually shortened to the capital adequacy ratio. It is the sum of Tier one and Tier two capital divided by risk weighted assets, expressed as a percentage. Risk weighting is the key idea: a loan to the sovereign carries a low weight and an unsecured personal loan a high one, so two banks with the same balance sheet size may need very different amounts of capital.

The Indian numbers

The Reserve Bank of India sets its minimum above the Basel figure. Indian banks must hold a capital to risk weighted assets ratio of nine per cent against the global eight, with Common Equity Tier one of five and a half per cent and total Tier one of seven per cent. On top of this sits the capital conservation buffer of two and a half per cent, to be met in Common Equity Tier one, which takes the effective requirement to eleven and a half per cent; a bank that dips into the buffer faces restrictions on dividends and bonuses. The last tranche of the buffer took effect on 1 October 2021. The leverage ratio, which compares Tier one capital with total exposure without any risk weighting, is set by the Reserve Bank at four per cent for domestic systemically important banks and three and a half per cent for other banks, against the Basel minimum of three.

Liquidity, buffers and related frameworks

Basel III added two liquidity standards. The Liquidity Coverage Ratio requires a bank to hold enough high quality liquid assets to meet its net cash outflows over a thirty day stress period, at a minimum of a hundred per cent. The Net Stable Funding Ratio requires available stable funding to be at least equal to required stable funding over a one year horizon, also at a hundred per cent. Basel III also introduced the countercyclical capital buffer, which a regulator can switch on when credit growth runs too fast, and an extra capital charge on systemically important banks. The Reserve Bank's framework for domestic systemically important banks, issued in 2014, places such banks in buckets and adds a Common Equity Tier one surcharge to each bucket. Finally, the Prompt Corrective Action framework lets the Reserve Bank place a weak bank under restrictions, and in its revised form it is triggered by three parameters: capital, asset quality measured by the net non performing assets ratio, and leverage.

Exam Point of View

Banking papers test this topic in five ways. First, institutional facts: the committee was formed in 1974, it sits at the Bank for International Settlements in Basel, and that Bank dates from 1930. Second, the accords by year and content, with the three pillars of Basel II asked by name and in order, and market discipline as the pillar candidates most often miss. Third, the composition of capital, where a question lists an item such as subordinated debt or revaluation reserves and asks which tier it belongs to; anything that protects depositors only in liquidation is Tier two. Fourth, the Indian numbers, where the trap is to offer the Basel eight per cent instead of the Indian nine, or ten and a half instead of eleven and a half once the buffer is added. Fifth, the Basel III additions: the thirty day Liquidity Coverage Ratio against the one year Net Stable Funding Ratio, the leverage ratio and the list of domestic systemically important banks.

Practice MCQs on this topic

Q1.Banking & Financial AwarenessEasy

The Basel norms for banks are issued by which body?

  1. A.The International Monetary Fund
  2. B.The Basel Committee on Banking Supervision
  3. C.The World Bank
  4. D.The Financial Action Task Force
Show answer

Correct answer: B. The Basel Committee on Banking Supervision

Explanation

The correct answer is B, the Basel Committee on Banking Supervision. It was set up in 1974 by the central bank governors of the Group of Ten countries and has its secretariat at the Bank for International Settlements in Basel, Switzerland. Its standards are recommendations and bind banks only once a national regulator adopts them. Option A is wrong because the International Monetary Fund looks after exchange rate stability and balance of payments support, not bank capital standards. Option C is wrong because the World Bank lends for development projects and poverty reduction and has no supervisory role over commercial banks. Option D is wrong because the Financial Action Task Force sets standards against money laundering and terrorist financing, a different subject that examiners often place beside Basel as a distractor. Remember the city, the committee and the Bank for International Settlements together.

Q2.Banking & Financial AwarenessMedium

The three pillars of Basel II are minimum capital requirements, supervisory review and which third pillar?

  1. A.Deposit insurance
  2. B.Market discipline
  3. C.Liquidity coverage
  4. D.Asset classification
Show answer

Correct answer: B. Market discipline

Explanation

The correct answer is B, market discipline. The third pillar works through disclosure: a bank must publish enough about its risk profile, capital and risk management for depositors, investors and rating agencies to judge it, so that the market itself exerts pressure for prudent behaviour. Option A is wrong because deposit insurance in India is handled by the Deposit Insurance and Credit Guarantee Corporation and is not part of the Basel pillars. Option C is wrong because liquidity coverage came in with Basel III in the form of the Liquidity Coverage Ratio and was not one of the three Basel II pillars. Option D is wrong because asset classification into standard, substandard, doubtful and loss categories is a Reserve Bank prudential norm rather than a Basel pillar. Recite the order: minimum capital, supervisory review, market discipline.

Q3.Banking & Financial AwarenessMedium

What is the minimum capital to risk weighted assets ratio prescribed by the Reserve Bank of India for Indian banks?

  1. A.Eight per cent
  2. B.Nine per cent
  3. C.Ten and a half per cent
  4. D.Twelve per cent
Show answer

Correct answer: B. Nine per cent

Explanation

The correct answer is B, nine per cent. The Reserve Bank has deliberately set the Indian minimum one percentage point above the Basel figure, so Indian banks must maintain a capital to risk weighted assets ratio of nine per cent, of which Common Equity Tier one must be at least five and a half per cent and total Tier one at least seven per cent. Option A is wrong because eight per cent is the Basel minimum applied internationally, not the Indian one. Option C is wrong because ten and a half per cent is the Basel III requirement once the capital conservation buffer of two and a half per cent is added to the global eight; the comparable Indian figure is eleven and a half per cent. Option D is wrong because twelve per cent is not prescribed. Remember the Indian pair: nine per cent plus a buffer of two and a half.

Q4.Banking & Financial AwarenessEasy

Which of the following forms part of Common Equity Tier one capital of a bank?

  1. A.Subordinated debt
  2. B.Revaluation reserves
  3. C.Paid up equity capital and statutory reserves
  4. D.General provisions against standard assets
Show answer

Correct answer: C. Paid up equity capital and statutory reserves

Explanation

The correct answer is C, paid up equity capital and statutory reserves. Common Equity Tier one is the purest form of going concern capital, able to absorb losses while the bank continues to trade, and it is made up of paid up equity capital, share premium, statutory reserves and retained earnings. Option A is wrong because subordinated debt is a Tier two instrument: it ranks below depositors and protects them only in liquidation. Option B is wrong because revaluation reserves, which arise from writing up the value of property, are also counted in Tier two and not in core equity. Option D is wrong because general provisions held against standard assets are likewise a Tier two item. The simple test is whether the money can absorb losses with the bank still running; only then is it Common Equity Tier one.

Q5.Banking & Financial AwarenessMedium

Basel III was issued in response to which event?

  1. A.The Asian financial crisis of 1997
  2. B.The global financial crisis of 2008
  3. C.The collapse of Bankhaus Herstatt in 1974
  4. D.The European sovereign debt crisis of 2015
Show answer

Correct answer: B. The global financial crisis of 2008

Explanation

The correct answer is B, the global financial crisis of 2008. The crisis showed that banks had too little capital of genuinely loss absorbing quality and no cushion of liquid assets, so the Basel Committee issued Basel III in 2010 with stricter definitions of capital, the capital conservation and countercyclical buffers, a leverage ratio and the two liquidity standards. Option A is wrong because the Asian crisis of 1997 prompted reforms of exchange rate and reserve management rather than a new Basel accord. Option C is wrong because the collapse of Bankhaus Herstatt in 1974 is the event that led to the creation of the Basel Committee itself, not to Basel III. Option D is wrong because the European sovereign debt troubles came after Basel III was already framed. Match each event to its outcome carefully.

Q6.Banking & Financial AwarenessHard

The capital conservation buffer prescribed under Basel III has to be maintained in which form of capital?

  1. A.Tier two capital
  2. B.Additional Tier one capital
  3. C.Common Equity Tier one capital
  4. D.Any combination of Tier one and Tier two
Show answer

Correct answer: C. Common Equity Tier one capital

Explanation

The correct answer is C, Common Equity Tier one capital. The buffer of two and a half per cent of risk weighted assets is meant to be built up in good years and drawn down in bad ones, so it must consist of the highest quality capital, that is common equity. A bank that lets the buffer fall faces curbs on dividends, share buybacks and bonus payments until it is rebuilt. Option A is wrong because Tier two capital protects depositors only in liquidation and cannot serve as a usable cushion for a bank still trading. Option B is wrong because Additional Tier one instruments, though they are going concern capital, are not accepted for the buffer. Option D is wrong because no combination is allowed; the requirement is specific. In India the buffer takes the effective requirement to eleven and a half per cent.

Q7.Banking & Financial AwarenessMedium

The Liquidity Coverage Ratio introduced under Basel III requires a bank to hold high quality liquid assets sufficient to meet net cash outflows over what period?

  1. A.Seven days
  2. B.Thirty days
  3. C.Ninety days
  4. D.One year
Show answer

Correct answer: B. Thirty days

Explanation

The correct answer is B, thirty days. The Liquidity Coverage Ratio is a short term standard: a bank must hold enough high quality liquid assets, mainly cash, central bank reserves and sovereign securities, to survive the net cash outflows of a thirty day stress scenario, and the ratio must be at least a hundred per cent. Option A is wrong because no Basel standard uses a seven day horizon. Option C is wrong because ninety days is not the measurement window for either liquidity standard. Option D is wrong because one year is the horizon of the other Basel III liquidity rule, the Net Stable Funding Ratio, which compares available stable funding with required stable funding. Keep the pair straight: thirty days for the Liquidity Coverage Ratio, one year for the Net Stable Funding Ratio, both at a hundred per cent.

Q8.Banking & Financial AwarenessEasy

The Basel Committee on Banking Supervision has its secretariat at which institution?

  1. A.The Bank for International Settlements
  2. B.The European Central Bank
  3. C.The Swiss National Bank
  4. D.The Organisation for Economic Co operation and Development
Show answer

Correct answer: A. The Bank for International Settlements

Explanation

The correct answer is A, the Bank for International Settlements. The Bank is located in Basel, Switzerland, was established in 1930 and is the oldest international financial institution in the world; it is often described as the bank for central banks because its members are central banks rather than private customers. The Basel Committee sits within it, which is how the accords took the city's name. Option B is wrong because the European Central Bank, based in Frankfurt, conducts monetary policy for the euro area. Option C is wrong because the Swiss National Bank is simply the central bank of Switzerland and does not host the committee. Option D is wrong because the Organisation for Economic Co operation and Development, based in Paris, works on economic policy research and tax matters.

Q9.Banking & Financial AwarenessHard

Under the Reserve Bank of India framework, which three banks have been designated as Domestic Systemically Important Banks?

  1. A.State Bank of India, Punjab National Bank and Bank of Baroda
  2. B.State Bank of India, ICICI Bank and HDFC Bank
  3. C.HDFC Bank, Axis Bank and Kotak Mahindra Bank
  4. D.State Bank of India, Canara Bank and Union Bank of India
Show answer

Correct answer: B. State Bank of India, ICICI Bank and HDFC Bank

Explanation

The correct answer is B, State Bank of India, ICICI Bank and HDFC Bank. The Reserve Bank issued its framework for Domestic Systemically Important Banks in 2014 and has since placed these three in the list, on the view that their size, interconnectedness and complexity make their failure a danger to the whole system. Each is put in a bucket and must hold an additional Common Equity Tier one surcharge, and the leverage ratio required of them is four per cent against three and a half for other banks. Option A is wrong because Punjab National Bank and Bank of Baroda, though large public sector banks, are not on the list. Option C is wrong because Axis Bank and Kotak Mahindra Bank have not been designated. Option D is wrong for the same reason regarding Canara Bank and Union Bank of India.

Q10.Banking & Financial AwarenessMedium

Basel I, issued in 1988, dealt mainly with which type of risk?

  1. A.Operational risk
  2. B.Market risk
  3. C.Credit risk
  4. D.Liquidity risk
Show answer

Correct answer: C. Credit risk

Explanation

The correct answer is C, credit risk. The first accord was a simple framework that asked banks to hold capital equal to at least eight per cent of their risk weighted assets, with risk weights of zero, twenty, fifty and a hundred per cent assigned according to the creditworthiness of the borrower. India adopted it in 1992. Option A is wrong because operational risk, the risk of loss from failed processes, people, systems or external events, was brought into the capital charge only with Basel II in 2004. Option B is wrong because market risk, arising from movements in interest rates, exchange rates and prices, was added through an amendment after Basel I and formalised under Basel II. Option D is wrong because liquidity risk was addressed only in Basel III through the Liquidity Coverage Ratio and the Net Stable Funding Ratio.

Frequently Asked Questions

What is the capital adequacy ratio?

It is the ratio of a bank’s capital to its risk weighted assets, written as Tier one plus Tier two capital divided by risk weighted assets and expressed as a percentage. It measures how much of a loss a bank can absorb before depositors are at risk, and it is also called the capital to risk weighted assets ratio.

What are the three pillars of Basel II?

Pillar one is the minimum capital requirement covering credit, market and operational risk. Pillar two is the supervisory review process, under which the regulator can require more capital than the minimum. Pillar three is market discipline, achieved through disclosure so that depositors and investors can judge the bank.

Why is the Indian minimum nine per cent and not eight?

The Basel standards are a floor, and national regulators may be stricter. The Reserve Bank of India has set the minimum capital to risk weighted assets ratio one percentage point above the Basel figure, at nine per cent, as an additional cushion for the Indian banking system.

What is the difference between Tier one and Tier two capital?

Tier one is going concern capital: it absorbs losses while the bank is still trading, and its purest part is Common Equity Tier one made up of paid up equity, share premium, statutory reserves and retained earnings. Tier two is gone concern capital, which protects depositors only in liquidation, and it includes subordinated debt, revaluation reserves and general provisions.

What is the capital conservation buffer?

It is an extra two and a half per cent of risk weighted assets, held in Common Equity Tier one, built up in good years so that it can be drawn down in bad ones. A bank that lets it fall faces restrictions on dividends, buybacks and bonuses until it is restored.

Which banks are Domestic Systemically Important Banks in India?

The State Bank of India, ICICI Bank and HDFC Bank. The Reserve Bank issued the framework in 2014 and places such banks in buckets, each carrying an additional Common Equity Tier one surcharge because their failure would threaten the whole financial system.
