NBFC layers under Scale-Based Regulation: which one you are in, and what changes
CS Manoj Famra · Regulatory · 2026-08-11 · 6 min read (estimated)
Your layer under scale-based regulation is no longer a classification you establish once and forget. It is also not the only label your NBFC carries — the layer sits alongside the category on your certificate of registration, and the two answer different questions; if that pairing is what you are here about, start with why your NBFC has two labels, not one. Later instruments key off it directly — the prepayment charges Directions bar an Upper Layer NBFC outright, cap a Middle Layer one at ₹50 lakh, and name the Base Layer in neither. Knowing which layer you are in is now an input to what your systems must enforce.
Scale-Based Regulation (RBI/2021-22/112, 22 October 2021, effective 1 October 2022) replaced a single rulebook with four layers. Most NBFCs read it once, established they were in the Base Layer, and moved on. That was reasonable in 2022 and is no longer enough, because later instruments have started keying off the layer directly.
What are the four layers?
Base Layer — asset size below ₹1,000 crore, plus P2P platforms, account aggregators, NOFHCs, and NBFCs with neither public funds nor public interface.
Middle Layer — all deposit-taking NBFCs regardless of size, and non-deposit-taking NBFCs at ₹1,000 crore and above. Standalone primary dealers, infrastructure debt funds, core investment companies, housing finance companies and infrastructure finance companies sit here whatever their size.
Upper Layer — identified by name by the Reserve Bank, on a scoring methodology. You do not arrive here by growth alone; you are told.
Top Layer — empty by design, and populated only if systemic risk from a specific company rises.
Why the layer stopped being trivia
The Pre-payment Charges Directions, 2025 are the clearest example. They bar prepayment charges on business loans by naming entity classes — NBFC-UL outright, NBFC-ML up to ₹50 lakh — and say nothing about the Base Layer, which therefore falls to the residual paragraph and its own board policy.
The strings "NBFC-BL" and "Base Layer" do not appear in that instrument at all. A Base Layer NBFC that assumed the stricter reading applied to it would be refusing itself a charge it is lawfully entitled to levy; one that crosses into the Middle Layer and does not notice would be levying one it is not.
What to write down rather than remember
Two things worth having written down rather than remembered.
The layer is a fact about the company on a date, and asset size moves. A company approaching ₹1,000 crore should know which of its rules change on the day it crosses, not discover it at the next inspection.
Systems that encode a regulatory test have to encode the layer, not a constant. A prepayment rule hard-coded to one answer is correct for exactly one class of lender and silently wrong for the others — and the failure is invisible, because a charge that should have been levied and was not produces no error anywhere.
What does the layer decide in practice?
| Area | Base Layer | Middle Layer | Upper Layer |
|---|---|---|---|
| Prepayment charges, business loans to individuals/MSE | Per approved policy | Barred up to ₹50 lakh sanctioned | Barred, no threshold |
| Governance requirements | Lighter | Higher | Highest, including a listing requirement |
| Risk management | Board policy | Prescribed functions | Prescribed functions and CRO |
| Disclosure | Lighter | Expanded | Expanded |
| Internal capital adequacy | — | — | Required |
The row that matters day to day is the first, because it is the one a system enforces on every foreclosure quote. The rest are organisational.
Common mistakes
- Applying a higher layer's rule to yourself. Enforcing a restriction the regulator declined to
impose is not conservatism; it is a commercial decision made by mistake.
- Assuming the layer follows only from asset size. All deposit-taking NBFCs are Middle Layer
whatever their size, and several categories sit there by type.
- Assuming you can grow into the Upper Layer. Upper Layer entities are identified by the Reserve
Bank by name, on a scoring methodology.
- Hard-coding the layer in the software. It changes, and when it does every rule that keys off it
has to change with it.
- No record of which layer was in force when a decision was taken. A charge levied under the old
layer is not wrong because the layer later changed.
How this lands in a lending system
The layer should be configuration on the tenant, not an assumption in code, because the rules that read it will multiply. Today it decides the prepayment charge treatment. It already shapes what returns apply. It will decide more.
The second requirement is that a change of layer is a dated event, not an edit. A loan foreclosed last year under Base Layer treatment was correctly treated then, and a system that recomputes history against today's layer will make past decisions look wrong.
Frequently asked questions
How does an NBFC know which layer it is in?
Base and Middle Layer follow from the criteria — asset size, deposit-taking status, and category. Upper Layer entities are identified by name by the Reserve Bank on a scoring methodology, and are told; you do not arrive there by growth alone. The Top Layer is empty by design.
Does the layer affect prepayment charges?
Directly. The 2025 Pre-payment Charges Directions bar an Upper Layer NBFC from levying them on business loans to individuals and MSEs with no threshold, bar a Middle Layer NBFC up to ₹50 lakh sanctioned, and name the Base Layer in neither limb — so a Base Layer NBFC charges per its board-approved policy.
Do all deposit-taking NBFCs sit in the Middle Layer?
Yes, regardless of asset size, along with standalone primary dealers, infrastructure debt funds, core investment companies, housing finance companies and infrastructure finance companies.
What happens when an NBFC moves between layers?
The obligations of the new layer apply from the transition, and the software has to treat the change as a dated event rather than a retrospective restatement — decisions taken correctly under the previous layer were correct when taken.
Should the layer be configurable in the software?
Yes. More instruments key off it every year, and a layer hard-coded in application logic is a change request every time one of them moves.
