Analysing banks through their financial ratios will accomplish two goals. First, to determine how well a bank has managed its risk and capital. And provide insight into the type of activity undertaken by the bank as well as its financial health.
The analysis of financial ratios is not limited to the above two goals; they also provide a wealth of information regarding the bank's profitability and the quality of its assets. A proper understanding of financial ratios is critical for evaluating the overall stability of any financial institution.
Ratios are indicators, not standalone conclusions
Non-Performing Assets (GNPA & NNPA)
Importance of Lower Ratios: Maintaining higher quality loan portfolios typically means lower GNPA and NNPA ratios, as well as higher efficiency in managing loans, which reduces stress on the bank’s balance sheet.
Quarterly Reports and Public Disclosure: All banks report GNPA and NNPA ratios on a quarterly basis to their shareholders in quarterly financial results and regulatory disclosures. These published ratios enable financial analysts to monitor the quality of bank assets over time, allowing them to assess the long-term viability of the banks' core lending operations.

Provisioning Coverage Ratio (PCR)
Provisioning Coverage Ratio measures the extent to which a bank has made provisions for bad loans.
PCR Formula: (Total Provisions / Gross NPAs) x 100
A higher PCR indicates the bank is more prepared to absorb losses from NPAs.
It helps safeguard depositors' interests in case of defaults.
PCR above 70% is generally considered a healthy benchmark by some industry observers, though this is not a regulatory mandate.
This ratio helps assess how conservatively a bank has accounted for potential loan losses.
Capital Adequacy Ratio (CAR)
The Capital Adequacy Ratio (CAR) reflects a bank's ability to meet its obligations and absorb potential losses. It is a critical indicator under Basel norms.
CAR Formula: (Tier 1 + Tier 2 Capital) / Risk-Weighted Assets
The Reserve Bank of India requires Indian banks to maintain a CAR of at least 9%.
A higher CAR implies the bank has adequate capital to cover risk-weighted assets.
This ratio ensures that banks operate securely, minimising the risk of insolvency.
Current Account Savings Account (CASA) Ratio
CASA ratio indicates the proportion of a bank's deposits that are in current and savings accounts.
CASA Formula: (CASA Deposits / Total Deposits) x 100
A higher CASA ratio is typically beneficial, as these accounts have lower interest obligations.
It helps in reducing the bank’s cost of funds.
Banks with a higher CASA ratio generally have stronger liquidity positions.
Tracking this ratio helps analyse how efficiently a bank is sourcing low-cost deposits.
Net Interest Margin (NIM)
Core Profitability Measurement: Net Interest Margin (NIM) measures the difference between how much interest a bank collects on loans and how much interest it pays on deposits. A bank with a healthy NIM is earning a higher interest spread from lending activities.
Operational Efficiency Indicator: NIM provides an indicator of how well a bank can operate its loan and deposit portfolios. By measuring the NIM over time, analysts will be able to see whether the bank is doing a good job at pricing its loans and keeping its deposit cost low.
Impact of Market Strategy: Banks typically use different strategies based on the mix of assets they hold, current interest rates, and their overall corporate direction. The changes in NIM will allow analysts to evaluate how effectively a bank can adjust to economic fluctuations while still producing income.
Price to Book (P/B) Ratio
The price-to-book ratio compares a bank's market valuation to its book value.
P/B Formula: Market Price per Share / Book Value per Share
A lower P/B ratio may indicate undervaluation, whereas a higher ratio could reflect investor confidence.
Investors widely use it to assess whether a bank’s stock is reasonably priced.
This ratio is applicable when comparing banks with similar asset bases but varying market performances.
