Indian Banks Grapple with Slowing CASA Growth, Resort to Costlier Funds

Indian banks are increasingly grappling with a slowdown in the growth of their Current Account Savings Account (CASA) deposits, a critical and low-cost source of funds. This decelerating trend is compelling financial institutions to explore more expensive avenues for capital, potentially impacting their profitability and overall lending rates.

Traditionally, CASA deposits, which include funds held in current and savings accounts, offer banks a significant advantage due to their low-interest payout structure. However, recent trends indicate a shift in customer behaviour, with depositors increasingly opting for higher-yielding instruments like fixed deposits, especially in a rising interest rate environment. Intense competition among banks for deposits also contributes to this challenge.

To compensate for the slower CASA accretion, banks are now heavily relying on term deposits, such as fixed and recurring deposits, which command higher interest rates. While these provide stable funding, they significantly increase the banks' cost of funds. Some institutions might also explore wholesale funding options, which can be even more volatile and expensive depending on market conditions.

This strategic pivot towards costlier funding sources is expected to exert pressure on banks' net interest margins (NIMs), a key measure of profitability. Higher funding costs could also translate into elevated lending rates for borrowers, impacting various sectors of the Indian economy from retail loans to corporate credit. Maintaining a healthy balance between deposit growth and managing the cost of funds remains a crucial challenge for the banking sector.
