The CAMEL rating approach was used to assess the performance of ICICI Bank Ltd before and after a merger. The study looked at factors like capital adequacy, asset quality, management efficiency, earning quality, and liquidity. The findings showed that while the bank improved its capital adequacy and asset quality before the merger, its management efficiency and earning quality did not show the same level of improvement after the merger. However, the bank did have a better liquidity position post-merger compared to pre-merger.
