Why RBI Rate Hikes Don’t Slow Every Bank
In India, when a business needs money, it usually doesn’t go to the stock market first. It walks into a bank.
That’s why when the Reserve Bank of India (RBI) changes interest rates, the expectation is simple: banks should adjust their lending accordingly.
If RBI raises rates → borrowing becomes expensive → banks slow down lending.
If RBI cuts rates → borrowing becomes cheaper → banks lend more.
But reality is not always that straightforward.
Researchers from Indira Gandhi Institute of Development Research (IGIDR) studied Indian banks and found an interesting pattern. The strength of a bank’s balance sheet changes how it reacts to RBI decisions.
A key concept here is the Bank Capital Ratio (BCR).
It measures how much financial cushion a bank has compared to its total assets.
Think of it like this.
Two banks face an RBI rate hike.
• Bank A has strong capital reserves.
• Bank B has a thin financial cushion.
When borrowing costs rise, Bank B feels pressure immediately. Its margins shrink, investors worry, and it reduces lending quickly.
But Bank A can absorb the higher cost. With stronger reserves and easier access to funding, it continues lending almost normally.
This creates a paradox.
Strong banks are safer for the financial system. But they are also less responsive to RBI rate hikes.
Data from 18 Indian banks (2002–2018) showed that a 100 basis point rate hike reduced overall credit growth by about 1.1%, but well-capitalized banks barely changed their lending behavior.
During the 2014–2018 NPA crisis, even strong banks slowed lending because bad loans eroded their real capital strength.
Another global insight from BIS research adds the other side of the story: when interest rates fall, well-capitalized banks expand lending much faster than weaker banks.
So capital acts like a shock absorber.
