What is Capital Adequacy Ratio?

Capital adequacy is a measure to find out the proportion of banks capital, with respect to the total risk-weighted assets of the bank. The credit risk attached to the assets depends on the entity the bank is lending loans to, for example, the risk attached to a loan it is lending to the government is 0% but the amount of loan lends to the individuals are very high in percentage.

• The ratio is represented in the form of a percentage, generally higher percentage implies for safety. A low ratio indicates that the bank does not have enough capital for the risk associated with its assets and it can go bust with any adverse crisis, something which happened during the recession.
• A very high ratio can indicate that the bank is not utilizing its capital optimally by lending to its customers. Regulators worldwide have introduced Basel 3 which requires them to maintain higher capital with respect to the risk in the books of the company, in order to protect the financial systems from another major crisis.

Formula

• The total capital which is the numerator in the capital adequacy ratio is the summation of Tier 1 capital of the bank and tier 2 capital of the bank.
  • The tier 1 capital which is also known as the common equity tier 1 capital includes mainly share capital, retained earnings, other comprehensive income, intangible assets, and other small adjustments.
  • The tier2 capital of a bank includes revaluation reserves, subordinated debt, and related stock surpluses.
• The denominator is risk-weighted assets. The risk-weighted assets of a bank include credit risk-weighted assets, market risk-weighted assets, and operational risk-weighted assets. The ratio is represented in the form of a percentage; generally higher percentage implies safety for the bank.

The mathematical representation of this Formula is as follows –

Examples (with Excel Template)

Let’s see some simple to advanced examples of Capital Adequacy Ratio (CAR) Formula to understand it better.

Example #1

Let us try to understand the CAR of an arbitrary bank in order to understand how to calculate the ratio for banks. For the calculation of CAR, we need to assume the tier 1 and tier 2 capital of the bank. We also need to assume the risk associated with its assets, those risks weighted assets are Credit risk-weighted assets, and Market risk-weighted assets and Operational risk-weighted assets.

The snapshot below represents all the variables required to calculate the CAR.

For the calculation of Capital adequacy ratio formula, we will first calculate the Total Risk-weighted assets as follows,

Total Risk-weighted Assets = 1200+350+170 =1720

Calculation of Capital adequacy ratio formula will be as follows,

CAR Formula = (148+57) /1720

CAR will be –

CAR = 11.9%

The ratio represents the CAR for the bank is 11.9%, which is a pretty high number and is optimal to cover the risk it is carrying in its books for the assets it holds.

Example #2

Let us try to understand the CAR for State Bank of India. For calculation of Capital Adequacy Ratio (CAR), we need the numerator which is the tier 1 and tier 2 capital of the bank. We also need the denominator which is the risk associated with its assets, those risks weighted assets are Credit risk-weighted assets, Market risk-weighted assets, and Operational risk-weighted assets.

The snapshot below represents all the variables required to calculate the CAR formula.

For the calculation of Capital adequacy ratio, we will first calculate the Total Risk-weighted assets as follows,

Calculation of Capital adequacy ratio will be as follows,

CAR Formula = (201488+50755) / 1935270

CAR will be –

Capital Adequacy Ratio = 13.0%

Example #3

Let us try to understand the CAR for ICICI. For the calculati0n of Capital adequacy ratio, we need the numerator which is the tier 1 and tier 2 capital of the bank. We also need the denominator which is the risk-weighted assets.

The snapshot below represents all the variables required to calculate the Capital adequacy ratio.

For the calculation of Capital adequacy ratio, we will first calculate the Total Risk-weighted assets as follows,

Total Risk-weighted assets =5266+420+560 = 6246

Calculation of Capital adequacy ratio will be as follows,

CAR Formula = (897+189) / 6246

CAR will be –

Capital Adequacy Ratio =17.39%

The ratio represents the CAR for the bank is 17.4%, which is a pretty high number and is optimal to cover the risk it is carrying in its books for the assets it holds. Also, find below the snapshot for the company reported numbers.

Relevance and Use of Capital Adequacy Ratio Formula

CAR is the capital which is set aside by the bank that acts as a cushion for the bank for the risk associated with the assets of the bank. A low ratio indicates that the bank does not have enough capital for the risk associated with its assets. Higher ratios will signal safety for the bank. This plays a very important role in analyzing banks globally post-subprime crisis.

A lot of banks have been exposed and their valuation plummeted as they were not maintaining the optimal amount of capital for the amount of risk they had in terms of credit, market and operational risks in their books. With the introduction of Basel 3 measure, the regulators have made the requirements far more stringent from earlier Basel 2, in order to avoid one more crisis in the future. In India a lot of public sector banks have fallen short of CET 1 capital and the government has been infusing these requirements over the last few years.
