Banking & NBFC

This industry exists because savers and borrowers rarely have matching needs at the same time. A household wants its savings safe and accessible; a business wants a large, long-term loan it cannot get any single saver to provide alone. Banks and NBFCs exist specifically to bridge that mismatch, pooling many small deposits or wholesale borrowings into loans large enough, and patient enough, to actually fund a business, a home or a farm.

The second reason is trust infrastructure. Lending money to a stranger is inherently risky, which is why this industry exists as a heavily regulated, closely supervised system, RBI oversight, capital adequacy rules, deposit insurance, precisely so that ordinary savers can trust an institution with their money without needing to personally assess every borrower that institution ultimately lends to.

Banking and NBFCs together form the plumbing that moves savings into productive lending across the rest of the economy. Banks take deposits and lend, NBFCs mostly borrow wholesale and lend, and the two increasingly work together, through co-lending especially, to reach borrowers neither could serve as profitably alone. Almost every other industry on this site depends on this one for the capital that actually funds its growth.

India's banking story right now is a genuine turnaround: gross NPAs at a multi-decade low after a brutal mid-2010s stress cycle, credit growth accelerating, and a fast-growing NBFC sector now managing over Rs 50 lakh crore in assets. The less celebrated fact sitting alongside that success is how modest India's banking sector still looks globally, only one Indian bank, SBI, ranks among the world's top 50.

Every bank and NBFC ultimately runs the same basic trade: borrow at one cost, lend at a higher one, and keep the difference. Net Interest Margin captures that spread in a single number, and almost every other concept on this page, CASA ratio, repo rate transmission, capital adequacy, exists either to protect that margin or to determine how much risk the lender can safely take while earning it.

This is why a bank's CASA franchise, its funding cost advantage, matters as much to analysts as its loan growth, and why NBFCs, funded at a structurally higher cost than deposit-taking banks, have had to build genuinely differentiated underwriting or distribution advantages, reaching borrowers banks cannot serve as easily, just to compete on the same margin banks earn more cheaply by default.

Banking is not a large direct trade item, but it sits close to the centre of India's capital flow story, foreign portfolio and institutional investment into Indian bank and NBFC bonds and equity is a meaningful, rate-sensitive category of capital inflow, and Indian banks' own overseas branches and correspondent banking relationships underpin much of India's international trade finance.

The more striking number is domestic: the dramatic asset quality turnaround. System gross NPAs fell from 9.11% in March 2021 to roughly 2.1% by September 2025, a multi-decade low, while net NPAs sit at just 0.5%, reflecting both aggressive recognition of bad loans through IBC and SARFAESI, and a genuinely more disciplined underwriting culture since the mid-2010s stress cycle that originally forced this cleanup.

Banks earn primarily through Net Interest Margin, the spread between what they pay on deposits (especially cheap CASA deposits) and what they earn on loans, supplemented by fee income from cards, transactions and cross-selling other financial products.

NBFCs earn on a similar spread, but starting from a structurally higher cost of funds since they cannot take deposits, which is why NBFC business models tend to concentrate in segments, vehicle finance, gold loans, unsecured personal loans, MSME lending, where their underwriting speed, flexibility or specialised expertise can command a pricing premium large enough to still be profitable despite that funding disadvantage.

For a bank, the dominant recurring cost is interest paid on deposits, which is why CASA ratio, effectively how much of that cost a bank can avoid altogether, is one of the most closely watched numbers in the entire industry.

For an NBFC, the dominant recurring cost is interest paid on wholesale borrowings and bonds, structurally higher than a bank's deposit cost, and highly sensitive to the credit rating and perceived stability of the NBFC itself, which is exactly why Asset-Liability Management discipline, and the lessons of the IL&FS crisis, matter so directly to an NBFC's actual cost of doing business.

Over the next five years, expect continued credit growth in the mid-to-high teens, further NBFC-bank co-lending expansion, deeper Scale-Based Regulation refinement, and continued asset quality strength assuming no major credit cycle disruption.

The bigger structural question is whether Indian banking's global scale can catch up to India's own economic growth, having only one bank in the world's top 50 despite being among the largest economies is a gap that will take genuine consolidation, capital raising and international expansion, not just domestic credit growth, to close.
