The Capital Adequacy Ratio (CAR), also referred to as the Capital to Risk (Weighted) Assets Ratio (CRAR), is a crucial metric used to assess a bank’s financial stability. It represents the ratio of a bank’s capital to its risk-weighted assets, providing insights into the institution’s ability to absorb potential losses. A higher CAR indicates that a bank has sufficient capital to cover its liabilities and manage various risks, including credit and operational threats. Consequently, banks with a robust CAR are less likely to face insolvency, thereby safeguarding depositors’ funds.
Significance of CAR
Following the financial crisis of 2008, the Bank for International Settlements (BIS) implemented stricter CAR requirements to enhance depositor protection and bolster the stability of the global financial system. Regulatory bodies worldwide monitor and enforce CAR levels to ensure that banks can withstand reasonable losses and comply with mandatory capital requirements. This oversight is essential for maintaining depositor confidence and ensuring the overall efficiency and stability of financial systems.
How CAR is Calculated
The calculation of CAR involves dividing a bank’s total capital by its risk-weighted assets. The capital is classified into two primary tiers:
Tier-1 Capital (Core Capital):
This category includes the core funds available to absorb losses without disrupting the bank’s operations. Tier-1 capital typically consists of equity capital, ordinary share capital, intangible assets, and retained earnings. It reflects the bank’s capacity to manage regular risks associated with activities like trading, investing, and lending.
Tier-2 Capital:
This tier encompasses less secure forms of capital, including unaudited retained earnings and general loss reserves. While it can help absorb losses during liquidation, it is considered a secondary line of defense compared to Tier-1 capital.
Risk-Weighted Assets
Risk-weighted assets (RWAs) are calculated by categorizing bank’s assets based on their associated risk levels. Different classes of assets, such as loans, cash, and investments, are assigned risk weights depending on their likelihood of default. For instance, unsecured loans carry a higher risk and are assigned greater weights than safer assets like cash and government securities.
The Basel Committee on Banking Supervision (BCBS) plays a vital role in establishing the rules for risk weighting. The Basel I framework initiated international banking regulation, setting initial capital requirements. This was further refined by the Basel II Accord in 2004, which recommended that banks maintain a capital level of at least 8% of their risk-weighted assets.
CAR Formula
To calculate the Capital Adequacy Ratio, the formula is straightforward:

Conclusion
The Capital Adequacy Ratio is a fundamental indicator of a bank’s resilience and financial health. By ensuring that banks maintain adequate capital levels relative to their risk exposure, regulatory frameworks aim to protect depositors and foster a stable financial environment. Understanding CAR not only aids in assessing individual banks but also contributes to the overall stability of the banking sector, making it a critical concept for regulators, investors, and customers alike.
