Small Finance Bank
A Small Finance Bank (SFB) is a differentiated scheduled commercial bank licensed by the RBI to primarily serve unserved and underserved segments such as small farmers, micro industries, and small businesses by providing basic banking services including deposits and loans. The RBI granted the first SFB licences in 2015.
Small Finance Banks were introduced to fill the credit gap left by traditional commercial banks, which found it commercially unviable to lend to small-ticket borrowers in rural and semi-urban India. The first batch of ten SFB licences was awarded by the RBI in 2015 to entities like AU Small Finance Bank, Equitas Small Finance Bank, Ujjivan Small Finance Bank, Jana Small Finance Bank, and Suryoday Small Finance Bank — many of which were microfinance institutions (MFIs) that converted to the banking model. Unlike payment banks, SFBs can lend, making them full-service banks despite their 'small' label.
The RBI's guidelines mandate that at least 75% of a Small Finance Bank's adjusted net bank credit (ANBC) must be deployed in priority sector lending — a significantly higher proportion than the 40% mandated for commercial banks. At least 50% of the loan portfolio must consist of loans and advances up to Rs 25 lakh. These guidelines ensured that SFBs remained focused on their developmental mandate rather than migrating upmarket toward large corporate loans that offered better risk-adjusted spreads.
Several SFBs that listed on stock exchanges demonstrated strong growth metrics in their early years, riding the underserved credit demand in tier-2 and tier-3 cities. However, the microfinance sector's stress during 2019–2020, compounded by COVID-19 disruptions, exposed the vulnerability of portfolios concentrated in unsecured small-ticket loans to low-income borrowers. NPA ratios spiked across several SFBs, and their cost of funds remained higher than universal banks since they could not access the same depositor base or wholesale funding at comparable rates.
For retail investors who track SFB stocks, key metrics include the gross NPA ratio, collection efficiency, return on assets (RoA), and the share of non-microfinance loans in the portfolio as the bank diversifies. Many SFBs aspired to eventually upgrade to universal bank status — a pathway the RBI opened subject to performance criteria — as that would reduce regulatory constraints on product offerings, loan ticket sizes, and geographic expansion. The SFB model thus represented an intermediate step in India's ongoing experiment with differentiated banking licences.
