Deposit your money with a bank and it pays you perhaps seven per cent. Borrow that same money back and it charges you nine, eleven, or far more. The gap can feel unfair, as if the bank is profiting twice on the same rupees, and in a sense it is. That gap, though, isn’t a trick. It’s the whole basis on which a bank stays in business.
A lender’s entire model rests on paying less for money than it earns on lending it out. Understanding where that difference goes explains not just why the two rates never meet, but why a borrowing rate is built the way it is.
The bank earns its living on the difference
A bank is, at heart, a middleman for money. It gathers funds from depositors, pays them a rate to hold that money, and lends it on to borrowers at a higher rate. The space between the two, the spread, is where its income comes from.
If it paid depositors the same rate it charged borrowers, it would earn nothing on the core of its business and couldn’t survive. So the lending rate has to sit above the deposit rate by design, not by greed. The deposit rate is a cost the bank pays; the lending rate is the price it charges. One being lower than the other is simply what keeps the machine running, the same way any business sells for more than it pays for its stock.
What sits inside the gap between the two rates?
The spread isn’t pure profit; several real costs are stacked inside it. The most important is risk. A depositor is almost certain to be repaid, so the bank pays them a modest, safe rate. A borrower might not repay at all, and the bank has to price that possibility of loss into every loan it makes.
On top of risk sit the bank’s running costs, staff, branches, technology, and regulation, which the spread has to cover. There’s also the plain matter of profit, since the bank answers to owners who expect a return. The deposit rate carries almost none of that load, which is why it sits so much lower.
Why does a riskier loan cost even more?
Because the risk portion of the spread scales with the borrower. Lending against a rock-solid pledge is nearly as safe as holding a deposit, so those loans are priced only a little above what the money cost the bank. Lending with no security at all, to someone whose repayment rests on their income alone, carries far more chance of loss, and the rate climbs to match.
That’s why an unsecured personal loan runs into the mid-teens or higher while a home loan stays in single digits, even at the same bank. The bank adds a bigger or smaller cushion depending on the risk each borrower represents, and that is all the rate difference reflects. The safer the lending, the closer its rate can sit to the deposit rate beneath it, though it can never quite touch it.
Where the deposit rate itself comes from
The rate paid on a fixed deposit is largely set by what it costs the bank to attract your money and what it can safely do with it. Because a depositor takes on very little risk, they’re rewarded with very little extra, a return that’s steady and secure rather than high.
An FD rate also moves with the broader interest-rate environment, rising when the central bank tightens and easing when it loosens. But wherever that baseline sits, the deposit rate is the floor the bank builds its lending rates on top of. It is deliberately the lower of the two figures, because it represents what the bank pays, not what it earns.
Can the two rates ever come close?
They can narrow, but they don’t converge. The gap is smallest exactly where the lending is safest, borrowing secured by the deposit itself, or by another asset the bank can rely on, where the risk cushion barely needs to exist. There, the lending rate can sit just a step above the deposit rate.
At the other end, for unsecured borrowing, the gap is at its widest because the risk premium is doing most of the work. What you never see is the lending rate dropping to or below the deposit rate, because that would mean the bank lending at a loss on its own funds. The spread can shrink to a sliver on the safest loans, but a sliver is as close as it gets.
What this means when you borrow and save at once
For anyone who both saves and borrows, the gap has a practical use: it tells you when to move money rather than borrow it. If a loan would cost you more than breaking or borrowing against a deposit, the deposit is the cheaper source, and the spread is precisely the sum you save by using your own money.
Seen this way, the difference between the two rates is information rather than something done to you. It shows what your safety as a depositor earns and what your risk as a borrower costs. The rates stay apart for good reason, and knowing why lets you use both sides of them.
