CASA Ratio in Indian Banks Hits Two-Year Low: Impact on Banking Profitability
CASA Ratio Decline: Understanding the Shift in Household Savings
According to the latest data from the Reserve Bank of India (RBI), the CASA (Current Account Savings Account) ratio of the Indian banking system fell to a two-year low of 37.9% in December 2025. This indicates a significant structural shift in how Indian households are managing their surplus funds.
What is CASA and Why Does It Matter?
CASA deposits are low-cost funds for banks compared to Term Deposits (Fixed Deposits). A higher CASA ratio allows banks to maintain a healthy Net Interest Margin (NIM) because the interest paid on savings accounts is much lower than on FDs.
Reasons for the Decline
- Investment Diversification: Retail investors are increasingly shifting their money from low-yielding savings accounts to higher-return assets like mutual funds, stocks, and gold.
- Interest Rate Gap: While banks have increased FD rates, savings account rates have remained stagnant, prompting customers to move funds into 'sweep-in' accounts or term deposits.
- Savings Share Drop: The share of savings accounts alone fell to 28.9%, driving the overall ratio down.
Impact on the Banking Sector
A lower CASA ratio means banks must rely more on costly bulk deposits and market borrowings to fund credit growth. This increases the cost of funds, potentially leading to higher lending rates for home and auto loans, and squeezed profit margins for banks.
For TNPSC and Banking aspirants, this is a key concept under "Indian Economy - Banking System," illustrating the challenges of liquidity management in a volatile market.
