ECL vs IRAC: What Changes for Indian Banks
IRAC is a rule-based incurred loss model — provisions kick in only after a borrower defaults at 90 DPD, at fixed rates. ECL is a forward-looking expected loss model — provisions are computed continuously using PD × LGD × EAD across all loans, including performing ones, adjusted for macroeconomic scenarios. ECL replaces the cliff-edged 90-DPD trigger with a gradual 3-stage migration framework.
India’s banking system is undergoing its most significant provisioning overhaul in decades. The shift from IRAC (Income Recognition and Asset Classification) to the ECL (Expected Credit Loss) framework is not a technical tweak — it is a philosophical change in how banks account for credit risk. Understanding the difference is essential for bankers, credit officers, risk professionals, and analysts tracking Indian banking.
The Core Philosophical Difference
The fundamental split between IRAC and ECL comes down to when a bank recognises a loss:
“We provision for a loss after it has happened.” A borrower must actually default (miss 90 days of payment) before a provision is booked. Until that point, even a visibly stressed account carries only the standard general provision.
“We provision for a loss before it happens, based on what we statistically expect.” Every performing loan carries a provision reflecting its probability of default, collateral recovery, and macroeconomic environment — computed at origination and updated continuously.
ECL vs IRAC: Side-by-Side Comparison
| Dimension | IRAC (Current) | ECL (New Framework) |
|---|---|---|
| Loss recognition model | Incurred loss — loss already happened | Expected loss — loss anticipated statistically |
| Provisioning approach | Rule-based, fixed rates by asset category | Model-driven, loan-level, PD × LGD × EAD |
| NPA / impairment trigger | 90 DPD — hard, deterministic rule | Stage 3 — 90 DPD + qualitative factors |
| Early stress recognition | SMA-0/1/2 flags but no extra provisioning | Stage 2 migration at SICR (30 DPD / PD jump) — full lifetime ECL |
| Performing loan provision | 0.25% standard assets; 1% for commercial real estate, etc. | 12-month ECL — varies by borrower’s PD, LGD, EAD (min 0.25% floor) |
| Macro sensitivity | None — provisions unchanged even in recession | Built-in — provisions rise when macro outlook deteriorates |
| Provision path as loan deteriorates | Flat at 0.25–1%, then sharp jump at 90 DPD (cliff-edged) | Gradual increase — Stage 1 → Stage 2 (lifetime ECL) → Stage 3 |
| P&L volatility | High — large one-off charges when accounts slip to NPA | Smoother — provisioning is spread over the deterioration cycle |
| Data and model dependency | Low — prescribed rates, minimal modelling | High — requires PD/LGD/EAD models, 5–10 yrs data, macro scenarios |
| International alignment | India-specific; diverges from global standards | Aligned with IFRS 9 — globally comparable bank financials |
The 90-DPD Cliff: Why It Was a Problem
Under IRAC, an account at 89 days overdue carries a general provision of 0.25% (for a standard term loan). The moment it crosses 90 days, it becomes an NPA — and the bank must book a provision of at least 15% (substandard category). For a ₹10 crore loan, this is the difference between a ₹2.5 lakh provision and a ₹1.5 crore provision — booked in a single quarter.
This cliff creates two damaging behaviours:
Banks had an incentive to restructure or rollover stressed loans just before 90 DPD to avoid NPA classification — kicking the problem forward without resolving the underlying credit deterioration.
Quarterly results swung sharply when stressed books were finally recognised as NPAs. Investors and analysts could not track the true health of a bank’s portfolio until the cliff hit.
ECL eliminates the cliff. An account at 30 DPD triggers SICR (Stage 2), requiring a full lifetime ECL provision — but this is a continuous, model-computed figure. The provision builds gradually as stress deepens, rather than arriving as a sudden shock.
What Happens to NPA Classification?
A common question: does ECL eliminate the concept of NPAs? No. RBI has retained the 90-DPD reference — Stage 3 assets are broadly equivalent to current NPAs. The difference is:
- Under IRAC, 90 DPD is a hard, mechanical trigger. An account is either standard or NPA — nothing in between for provisioning purposes.
- Under ECL, Stage 3 includes 90 DPD plus qualitative factors — fraud, legal action, expected restructuring — so an account can be Stage 3 before 90 DPD if evidence of credit impairment is clear.
- Stage 3 provisions are computed as lifetime ECL on an NPV basis, not at fixed IRAC rates. However, RBI has specified a backstop: Stage 3 ECL provisions must be at least equal to the equivalent IRAC NPA rates — so ECL can never produce less provisioning than IRAC for credit-impaired accounts.
Provisioning Example: Same Loan Under IRAC vs ECL
Consider a ₹5 crore term loan to a manufacturing company. The borrower misses a payment — 45 DPD. Here is how the two frameworks treat it:
| Position | IRAC — Provision | ECL — Provision |
|---|---|---|
| Loan performing (0 DPD) | ₹1.25 lakh (0.25% standard) | Stage 1 — 12-month ECL, e.g. ₹2–5 lakh (model-driven) |
| SMA-1 (30–60 DPD) | ₹1.25 lakh — no change (still standard) | Stage 2 — lifetime ECL triggered at 30 DPD, e.g. ₹15–30 lakh |
| SMA-2 (60–90 DPD) | ₹1.25 lakh — still no change | Stage 2 — ECL increases further as PD rises |
| NPA / Stage 3 (90 DPD) | ₹75 lakh (15% substandard) — sudden cliff | Stage 3 — lifetime ECL (min. ₹75 lakh floor); already partially built up |
The key difference: under ECL, the ₹75 lakh Stage 3 provision is not a sudden shock — it has been building since Stage 2 migration at 30 DPD. The P&L impact is smoothed across multiple quarters rather than hitting all at once.
Impact on Bank Operations: What Changes on the Ground
Banks must monitor every account continuously for SICR signals — not just at 90 DPD. Watchlist reviews, PD movements, and industry signals all drive real provisioning changes.
Loan origination data, PD at sanction, and collateral values must be retained and accessible for every account — sometimes for the full loan life of 20+ years for home loans.
Provisions will move each quarter based on PD/LGD model updates and macro scenario reviews. Investors and analysts must learn to interpret ECL-driven provision swings differently from IRAC cliff charges.
Excess ECL provisions over the regulatory backstop can be counted as Tier 2 capital (up to 1.25% of RWAs) — partially offsetting the Day 1 provision catch-up hit for under-provisioned banks.
What Stays the Same
It is equally important to understand what ECL does not change. RBI has been deliberate about ensuring ECL does not produce weaker safeguards than IRAC:
- The 90-DPD reference remains in Stage 3 — it is not abolished, only supplemented with qualitative factors
- Regulatory backstop floors ensure ECL provisions are never lower than current IRAC rates for any stage
- SARFAESI and DRT recovery processes remain unchanged — ECL affects provisioning, not the legal recovery framework
- RBI inspections and supervisory ratings (CAMELS) continue — ECL adds a new dimension to asset quality assessment
What is the main difference between ECL and IRAC?
IRAC is an incurred loss model — provisions are booked only after a borrower defaults at 90 DPD, at fixed rates prescribed by RBI. ECL is a forward-looking expected loss model — provisions are computed continuously using PD × LGD × EAD for every loan, including performing ones, adjusted for macroeconomic scenarios. ECL recognises stress earlier and eliminates the cliff-edged provisioning jump at 90 DPD.
Does ECL remove the concept of NPAs?
No. RBI has retained the 90-DPD reference under ECL — Stage 3 assets are broadly equivalent to current NPAs. The difference is that Stage 3 also includes qualitative factors (fraud, legal action, expected impairment) and provisions are computed as lifetime ECL on an NPV basis rather than at fixed IRAC rates. RBI’s backstop ensures Stage 3 ECL provisions are never lower than equivalent IRAC NPA provisioning rates.
Why did RBI move from IRAC to ECL?
IRAC had three structural problems: it was backward-looking (provisions only after default), cliff-edged (sharp P&L hit at 90 DPD), and macro-blind (provisions unchanged even during economic downturns). ECL fixes all three — provisions build gradually as credit quality deteriorates, and rise automatically when the macro outlook worsens. The shift also aligns India with IFRS 9, making Indian bank financials globally comparable.
Which banks must switch from IRAC to ECL?
All Scheduled Commercial Banks (SCBs) including PSBs, private banks, foreign banks, and Small Finance Banks must implement ECL. RRBs, co-operative banks, and Local Area Banks are excluded from the initial scope. A minimum two-year parallel run of both IRAC and ECL is required before full switchover.
Will ECL increase provisioning for performing loans?
Yes, in most cases. Under IRAC, a standard performing loan carries a flat 0.25–1% general provision. Under ECL Stage 1, the provision is the 12-month expected credit loss computed using the borrower’s actual PD and LGD — which for riskier borrowers will exceed the IRAC floor. However, RBI has set the Stage 1 backstop at the higher of 0.25% or the equivalent IRAC general provision, so ECL will not produce lower provisions than IRAC for performing assets.
