How Do Banks Differ From NBFCs in Credit Limit Framework Design?

September 3, 2026 By Yodaplus

Banks design credit limit frameworks around Basel III capital norms, deposit-funded balance sheets, and a uniform 9% minimum capital ratio, while NBFCs work within the Reserve Bank of India’s Scale-Based Regulation framework, hold a higher 15% capital adequacy requirement, and size limits without the deposit base banks rely on. The RBI’s June 2026 Financial Stability Report found banks stayed comfortably above Common Equity Tier 1 norms even under severe stress test scenarios, while the same stress tests projected 15 NBFCs could fall below regulatory capital requirements, a gap that shows up directly in how conservatively each type of institution has to size its credit limits.

The difference is not just regulatory paperwork. It changes how each institution actually builds and calibrates its limit-setting methodology.

Different Regulatory Foundations Drive Different Frameworks

Banks operate under the Banking Regulation Act, which grants them the ability to accept public deposits and anchors their credit limit frameworks in a stable, relatively low-cost funding base. NBFCs operate under the Reserve Bank of India Act, focused on lending, asset financing, and credit facilitation without the same deposit-taking privileges most banks enjoy.

This distinction cascades directly into limit design. A bank building its risk appetite framework can lean on stable deposit funding when calibrating how much credit risk it can absorb. An NBFC building the same framework has to account for its reliance on wholesale borrowing from banks, mutual funds, and capital markets, a funding source that can tighten quickly during periods of stress.

Capital Adequacy Requirements Set Different Limit Headroom

Banks maintain a minimum Capital to Risk Weighted Assets Ratio of 9%, with additional buffers layered on for systemically important institutions. NBFCs face a higher baseline requirement, generally around 15%, reflecting the additional risk regulators associate with non-deposit-taking lenders operating with less diversified funding.

This higher capital requirement directly shapes how NBFCs size credit limits. A bank with a 9% floor has more balance sheet capacity to extend against a given amount of capital than an NBFC holding the same capital base but required to maintain a higher ratio. NBFC credit limit methodologies typically build in tighter headroom against regulatory minimums as a result, since falling close to the 15% threshold carries immediate supervisory consequences.

Deposit Access Changes How Risk Gets Priced and Sized

Because banks fund lending largely through deposits, their cost of capital tends to run lower, which supports both lower interest rates and, often, larger limits for comparable borrower risk profiles. NBFCs, funding through wholesale borrowing, generally carry a higher cost of capital, which pushes their limit-setting methodologies toward faster approval and more flexible eligibility criteria to compensate through volume and speed rather than price.

This is a structural trade-off, not a difference in credit discipline. NBFCs often serve borrower segments banks decline, extending credit at higher rates that reflect both the borrower’s risk profile and the NBFC’s own higher funding cost.

Scale-Based Regulation Creates Tiered Limit Frameworks for NBFCs

The RBI’s Scale-Based Regulation framework classifies NBFCs into four layers, Base, Middle, Upper, and Top, based on asset size and systemic importance, with regulatory requirements becoming more stringent as an NBFC moves up the tiers. This means credit limit frameworks at a Base Layer NBFC, with assets below ₹1,000 crore, look meaningfully different from those at an Upper Layer NBFC specifically flagged for enhanced regulatory scrutiny.

Banks, by contrast, largely operate under a single Basel III framework with additional buffers scaled to systemic importance, rather than a distinct tiered regulatory category shifting core capital and limit requirements as the institution grows.

Where the Two Approaches Converge

Despite these structural differences, banks and NBFCs converge on several core credit limit practices. Both apply concentration limits capping exposure to single names, sectors, and geographies. Both increasingly mirror non-performing asset classification norms, with NBFC NPA rules now closely aligned with bank standards. Both use utilization thresholds within limits to trigger earlier management response before a hard breach occurs.

The convergence reflects regulatory intent: as NBFCs have grown to represent a larger share of credit delivery, particularly in gold loans, vehicle finance, and MSME lending, regulators have pushed their risk practices closer to bank standards even while capital requirements and funding structures remain distinct.

Common Challenges in Designing NBFC Credit Limit Frameworks

Funding volatility feeding into limit calibration Since NBFCs rely on wholesale funding rather than deposits, a tightening in that funding market can force faster limit reductions than a deposit-funded bank would need to make under similar credit conditions.

Tier-dependent regulatory shifts An NBFC crossing from one Scale-Based Regulation layer into the next faces materially different capital and governance requirements, requiring its credit limit framework to be rebuilt rather than simply adjusted.

Higher capital consumption per unit of lending The 15% CRAR requirement means NBFCs need to hold more capital against the same loan book size compared to a bank, tightening the headroom available for limit growth without additional capital raising.

Balancing speed with discipline NBFCs compete partly on faster approval and more flexible eligibility, which creates ongoing pressure to keep limit-setting methodologies fast without compromising the credit discipline regulators expect.

Best Practices for Designing Credit Limit Frameworks Across Bank and NBFC Structures

• Calibrate capital-based limits against the specific regulatory ratio that applies, recognizing NBFCs need tighter headroom against their higher CRAR floor
• Build funding volatility into NBFC limit models, since wholesale funding can tighten faster than deposit funding during stress
• Reassess limit frameworks whenever an NBFC crosses a Scale-Based Regulation tier, rather than treating tier changes as incremental
• Apply concentration limits at the sub-sector level for both banks and NBFCs, given how concentrated NBFC lending often is in specific segments like gold loans or vehicle finance
• Align NPA classification and provisioning practices with current regulatory expectations, which have moved closer between banks and NBFCs over time
• Use soft and hard utilization thresholds consistently across both institution types to catch limit pressure before a breach
• Monitor stress test outcomes specific to institution type, since aggregate banking sector resilience does not extend automatically to NBFC resilience
• Factor cost of capital differences into how aggressively each institution type can extend credit at a given risk level
• Build governance structures proportional to systemic importance, recognizing Upper Layer NBFCs warrant closer oversight than Base Layer entities
• Review limit frameworks against updated capital adequacy directions promptly, since regulatory amendments can shift lending headroom mid-year

Future Outlook

The RBI’s ongoing amendments to capital adequacy directions, including recent changes allowing NBFCs to include adjusted quarterly profits in owned fund calculations, suggest regulators are actively fine-tuning how much flexibility non-bank lenders get within an overall framework of tighter capital discipline. Expect continued convergence in risk practices between banks and NBFCs, even as the underlying capital and funding structures that shape limit design remain distinct.

Conclusion

Banks and NBFCs are not building credit limit frameworks from the same starting point. Different capital floors, different funding structures, and a tiered regulatory framework specific to NBFCs mean the methodology has to reflect the institution type, not just the borrower risk profile.
