Small Finance Bank Licensing: Criteria, Net Worth and the 75% PSL Rule

The small finance bank licensing framework is one of the RBI's boldest experiments in deepening financial inclusion, creating a class of niche banks built to serve the unbanked and underbanked. For IIBF certification candidates, mastering the small finance bank licensing norms, the 75% priority sector lending rule, and the road to becoming a universal bank is essential exam territory. This guide breaks down the eligibility criteria, capital requirements, and operating mandates that define the SFB model in India as of 2026.

What Small Finance Banks Are and Why RBI Created Them

Small finance banks (SFBs) are differentiated banks licensed under Section 22 of the Banking Regulation Act, 1949, designed to extend basic banking to segments that mainstream commercial banks have historically overlooked. The Reserve Bank of India introduced the category through its 2014 guidelines, awarding the first batch of in-principle approvals in September 2015. The original cohort drew heavily from microfinance institutions, NBFCs, and local area banks already working at the grassroots level.

The core objective is twofold:

• Savings mobilisation among small business units, marginal farmers, micro and small industries, and unorganised-sector entities.
• Supply of credit to these same underserved groups through high-technology, low-cost operations.

Unlike payments banks, SFBs can undertake the full range of basic banking activities — accepting deposits and lending — but they cannot establish subsidiaries to undertake non-banking financial activities. They must also operate without area restrictions, meaning they are national in scope rather than regional. This positioning makes SFBs a powerful instrument of inclusion, and understanding their mandate is foundational before you tackle the licensing arithmetic. You can test your grasp of these concepts with practice questions on our mock test series.

Small Finance Bank Licensing Criteria and Net Worth Norms

The small finance bank licensing process is governed primarily by the RBI's "on-tap" licensing guidelines released in December 2019, which replaced the earlier window-based approach with a continuously open application route. Eligibility and capital are the two pillars examiners focus on.

Who can apply

• Resident individuals and professionals with at least 10 years of experience in banking and finance.
• Companies and societies in the private sector that are owned and controlled by residents.
• Existing NBFCs, microfinance institutions (MFIs), and local area banks (LABs) controlled by residents.

Capital and net worth

• Minimum paid-up voting equity capital / net worth of Rs 200 crore is required. (For SFBs converted from urban co-operative banks, the entry net worth is Rs 100 crore, rising to Rs 200 crore within five years.)
• The bank must maintain a minimum Capital to Risk-Weighted Assets Ratio (CRAR) of 15% of its risk-weighted assets on a continuous basis — higher than the 9% baseline for universal banks because SFBs serve a riskier, smaller-ticket book.
• Promoters must hold a minimum of 40% of paid-up voting equity capital, locked in for the first five years, with a glide path to bring holding down to 15% over 15 years.

Aspiring SFBs must also list their equity on a stock exchange within three years of reaching a net worth of Rs 500 crore. Keep these figures sharp — they recur across IIBF papers and overlap heavily with the regulatory portions of the CAIIB syllabus.

The 75% Priority Sector Lending Rule and 50% Small-Ticket Mandate

If one number defines the SFB business model, it is the priority sector lending (PSL) requirement. While universal commercial banks must direct 40% of Adjusted Net Bank Credit (ANBC) to priority sectors, small finance banks face a far steeper obligation.

• 75% of Adjusted Net Bank Credit must be extended to priority sectors — nearly double the universal-bank norm. This is the regulatory heart of the SFB's inclusion mandate.
• Of this 75%, 40% of ANBC is allocated to the different sub-sectors under PSL as per the standard RBI norms applicable to all banks.
• The remaining 35% can be allocated to any one or more PSL sub-sectors where the bank has a competitive advantage, giving it some flexibility.

A second defining constraint targets loan size:

• At least 50% of the loan portfolio must consist of loans and advances of up to Rs 25 lakh, ensuring the bank stays focused on small borrowers rather than drifting upmarket.

These twin rules — 75% PSL and 50% small-ticket — together prevent mission drift and keep SFBs anchored to micro and small customers. They are also why SFBs typically run higher yields but tighter compliance overheads than universal banks. To reinforce these ratios, drill them with our quick-recall match-the-pairs game and cross-check current rate benchmarks on the RBI rates page.

MFI-to-SFB Transition and Building CASA

Most of India's marquee SFBs began life as microfinance institutions, and the MFI-to-SFB transition remains a recurring case study. Converting an MFI into a bank is transformative but operationally demanding.

Why MFIs convert

• Access to public deposits as a stable, lower-cost funding base, replacing dependence on bank borrowings and wholesale funds.
• Regulatory legitimacy and a wider product suite — savings accounts, fixed deposits, and remittances.

The CASA challenge

The single hardest task for a newly minted SFB is building a healthy Current Account and Savings Account (CASA) base. MFIs historically lent but never collected deposits, so they start with near-zero CASA and high-cost term deposits. SFBs typically attack this by:

• Offering higher savings-account interest rates than incumbent universal banks to attract first-time depositors.
• Converting existing borrower relationships into depositors through doorstep and digital banking.
• Investing in low-cost branch and business-correspondent networks in semi-urban and rural geographies.

A rising CASA ratio lowers the cost of funds and is the clearest signal of a maturing SFB. Once an SFB demonstrates a strong track record — typically five years of satisfactory performance and compliance — it can apply to transition into a universal bank, shedding the 75% PSL and 50% small-ticket constraints.
