Small Finance Banks in India: Licensing, PSL & Model for IIBF 2026

The small finance bank is one of the most important institutional innovations in India's financial inclusion story, and the IIBF paper tests its model in depth. A small finance bank is a differentiated bank designed to take banking to the unserved and underserved — small farmers, micro and small enterprises, and low-income households. This guide explains the licensing framework, the lending obligations and the business model that define this category.

Origin and Objectives

The small finance bank category was created on the recommendation of the Nachiket Mor Committee on financial inclusion, with the first licences issued in 2015-16. The objective is twofold: to provide savings vehicles to the underserved and to supply credit to small business units, marginal farmers and the unorganised sector through high-technology, low-cost operations. Many small finance banks evolved from successful microfinance institutions that already understood this customer base.

Unlike a microfinance institution, a small finance bank can accept deposits, which transforms its funding model and lowers its cost of funds over time. It is a full-fledged bank for its target segment but operates under a differentiated licence with specific obligations. For the exam, be clear on why the small finance bank was created and how it differs from both universal banks and payments banks. Practise these distinctions with our IIBF SFB practice tests, which contrast the different bank types.

Licensing and Capital Norms

Licensing of a small finance bank follows RBI guidelines, and an on-tap licensing window now allows eligible promoters to apply at any time. The minimum paid-up capital requirement is set by the RBI, and the promoter must maintain a minimum shareholding for an initial period before diluting. Promoters must be fit and proper with a sound track record, and foreign shareholding is permitted within the limits applicable to private banks.

A small finance bank must maintain the standard prudential requirements — the Cash Reserve Ratio and the Statutory Liquidity Ratio — like any other bank, and it must comply with capital adequacy norms with a prescribed minimum capital ratio. Within a defined period of commencing operations, it is required to list its shares. The bank cannot set up subsidiaries to undertake non-banking financial activities, keeping its focus narrow. Understanding these structural conditions is essential, since they distinguish the small finance bank from a universal bank. Reinforce the key numbers with our banking structures match game.

The 75% Priority Sector Lending Rule

The defining obligation of a small finance bank is its priority sector lending target. While universal banks must lend 40% of adjusted net bank credit to the priority sector, a small finance bank must extend 75% of its adjusted net bank credit to the priority sector. This near-doubling of the target hard-wires financial inclusion into the bank's balance sheet and reflects its core mandate.

Equally important is the loan-size rule: at least 50% of the bank's loan portfolio must consist of loans and advances of up to a prescribed small-ticket limit. This ensures the bank genuinely serves small borrowers rather than drifting towards large corporate loans. Detailed norms are issued by the Reserve Bank of India. For the exam, the 75% PSL figure and the small-ticket-loan condition are almost guaranteed questions, so commit them to memory along with the 40% universal-bank benchmark for comparison.

Building CASA and the Path Forward

The biggest strategic challenge for a small finance bank is building a stable, low-cost deposit base — particularly Current Account and Savings Account (CASA) balances. Coming from a lending-only microfinance background, these banks initially relied on bulk and term deposits, which are costlier. Offering attractive savings rates, leveraging technology for easy account opening, and deepening relationships with existing borrowers are the levers used to grow CASA and reduce the cost of funds.

Looking ahead, a well-performing small finance bank may aspire to transition to a universal bank once it meets the eligibility conditions on track record, net worth and asset quality. This transition path is itself a likely exam topic. The category has expanded credit access dramatically while remaining commercially viable, demonstrating that financial inclusion and sustainability can coexist. A banker who understands the small finance bank model grasps a key pillar of India's inclusive growth strategy. Stay current on policy changes via our IIBF news tracker.

Exam Strategy and Quick Revision

For this paper, build a comparison table of universal banks, small finance banks and payments banks across deposits, lending, PSL target and key restrictions. The contrasts — a small finance bank lends and takes deposits with a 75% PSL target, while a payments bank takes deposits but cannot lend — are the examiner's favourite multiple-choice material.

Memorise the headline numbers: the 75% priority-sector target, the 50% small-ticket-loan condition, and the listing requirement after commencing operations. Understand the MFI-to-SFB evolution and the SFB-to-universal-bank transition path, since these journeys frame several questions. Pair this focused revision with regular mock tests, and the small finance bank section becomes a dependable source of marks. Test yourself with a timed SFB mock and read more on our study blog.

Conclusion

The small finance bank model blends financial inclusion with commercial banking through differentiated licensing and a 75% priority-sector mandate.
