Your employer deposits ₹80,000 in your salary account. You think of it as cash to spend. The bank thinks of it as funding. Banks need money to make loans, buy securities and to fund their balance sheets. A salary account is valuable not only because the bank can eventually sell you a credit card. Your monthly salary is a steady supply of one of the most important inputs for a bank: deposits.
Banks Buy Money Before They Sell Money
A bank's business model is often summarised as taking deposits and converting them into loans. The fine print reveals that different deposits have different prices. A fixed deposit carries a higher cost (interest rate) for the bank compared to a current account. Savings accounts carry a lower rate than fixed deposits.
Current and savings accounts together are referred to as CASA deposits. A larger CASA base means lower cost of funding for the bank. Axis Bank ended FY2024-25 with ₹11.73 lakh crore of deposits. Of these, about ₹4.78 lakh crore were current and savings account balances, or 41% of total deposits. The bank has explicitly identified CASA as a source of stable and low-cost deposits. (AxisBank) Your account balance is miniscule compared to these numbers. Millions of accounts are not.
Why Banks Chase Employers
Banks are intensely focused on securing corporate salary relationships. The logic is straightforward: instead of chasing individual customers, a bank can partner with an employer and get access to hundreds or thousands of employees. Every month, the employer deposits salaries in the bank. Axis Bank explicitly lists salary credits as one of the ways in which it acquires retail deposits (AxisBank). The bank has not only got an account, but has attached itself to the customer's income.
Why the Account Can Be "Free"
Salary accounts typically do not require customers to maintain a certain quantum of money in the account, compared to regular savings accounts. Axis Bank's salary account terms include options with no monthly average balance requirement (AxisBank). Why would a bank remove a fee? Because the bank does not really care about the account, per se.
The bank wants the salary, the relationship and the deposits that come with it. Once the bank has the customer, it can upsell credit cards, personal loans, mortgages, mutual funds, insurance, forex, wealth management, bill payments and more. A customer who gets her salary in Bank A is likely to take loans and buy other products from the same bank as well. The free account is a customer acquisition device.
Deposits Become Earning Assets
A bank cannot lend out all the money it takes as deposits. It has to maintain liquidity, reserves, capital and provisioning cover. That said, deposits are a critical source of funding for earning assets. If a bank can fund these assets at a lower cost (interest rate) than the returns it earns on them, the difference accrues to the bank as net interest income. This is why competition for deposits is so fierce, especially when interest rates are rising.
Banks cannot keep funding loans and advances if deposits do not come in. If CASA deposits are growing slowly, a bank may have to offer higher interest rates on term deposits or raise other kinds of funding. HDFC Bank, for instance, has an average balance of about ₹26.58 lakh crore of deposits as of June 2025, reflecting the scale of competition for funding (HDFC Bank). The bank's business model is one of earning assets (loans) funded by deposits.
Your Salary Also Predicts Your Value
Salary relationships help banks identify customers who are likely to need more products and services. A regular salary deposit helps the bank understand the customer's income and employment status. Combined with credit bureau data and other information, it can help the bank identify customers for pre-approved offers. A customer with a ₹1.5 lakh monthly salary is clearly more valuable than one with no salary.
That is why banks are beginning to offer "pre-approved" credit cards, loans and other products. The bank already has a relationship with the customer, and is looking to cross-sell. The salary account is not an end, but a beginning.
The Valuable Customer Is the One Who Stays
A bank wants the customer to stick to its salary account, if not out of choice, at least out of habit. Your UPI address is with the bank. Your bills are paid via the bank. Your credit card is issued by the bank. Your mutual funds and gold are in the bank's apps. Your loan EMIs are routed through the same bank. It may still be possible to switch banks, but the effort required is high. Customer retention is critical for a bank, and a salary partnership can help it immensely.
The Bank Wants the Deposit Before the Loan
Consumers tend to think that banks are interested in lending to them. This is correct, but only in part. Banks are much more interested in getting deposits from customers. A large and stable deposit base funds a bank's balance sheet, allowing it to grow loans and advances. That is why banks compete intensely to get salary relationships with employers. Your employer thinks it is doing you a favour by depositing your salary with a particular bank. The bank, meanwhile, gets its next round of raw material.
