Banks make money by borrowing from depositors at low rates and lending at higher ones. The profit margin, however, disappears when loans go bad. Non-performing assets (NPAs) force banks to set aside money from profits to cover losses, a process called provisioning. For bank investors, understanding how banks account for these losses is crucial because it fundamentally shapes a bank's financial health.
The Current System
Indian banks currently use an "incurred loss" model, where they wait for problems to surface before provisioning. Loans overdue by 0-30 days fall into SMA-0 category, 31-60 days into SMA-1, and 61-90 days into SMA-2. Only after 90 days does a loan become an NPA, triggering meaningful provisions. Until then, banks set aside minimal reserves, even if a borrower shows signs of distress.
This reactive approach has a major flaw: it's slow to catch structural problems. By the time losses are recognized, crisis prevention becomes difficult. Critics call it "too little, too late."
The New ECL Framework
The RBI now proposes switching to an Expected Credit Loss (ECL) model, potentially causing a one-time hit of ₹60,000 crore across banks. Instead of waiting for defaults, ECL requires banks to anticipate losses upfront using three factors:
- Probability of Default (PD): likelihood of borrower default
- Loss Given Default (LGD): percentage of loan likely lost
- Exposure at Default (EAD): total amount at stake
Formula:
Expected Loss = PD × LGD × EAD
Under ECL, loans are classified into three stages:
- Stage 1: Healthy loans with no increased risk. Banks provision for 12 months of expected losses.
- Stage 2: Loans showing significant risk increase, though not yet defaulted. Banks must provision for lifetime expected losses, not just one year.
- Stage 3: Defaulted or credit-impaired loans, similar to current NPAs.
The impact is substantial. A loan 60 days overdue currently requires just 0.25–0.4% provision. Under ECL’s Stage 2, that jumps to 5%, a tenfold increase for the same loan.
The Subjectivity Problem
While ECL makes provisioning stricter, it also introduces judgment calls. Banks will build their own risk models and make assumptions about defaults and recoveries. Two banks could estimate vastly different loss rates for identical loans.
Done properly, this discretion helps banks that know their borrowers well. Done poorly, it allows banks to manipulate assumptions, using optimistic recovery rates or low default probabilities to minimize provisions and inflate profits.
The RBI addresses this through regulatory backstops, minimum floors that banks must meet regardless of their models. Stage 2 loans, for instance, require at least 5% provision even if internal models suggest less. These floors prevent excessive optimism and ensure baseline standards across all banks.
Will this eliminate fraud or loan evergreening? No. Determined banks can still hide problems. But ECL makes it harder to justify low provisions on stressed loans while giving auditors and regulators better visibility.
Global Context
India is following global trends. After the 2008 financial crisis, international bodies introduced IFRS 9, which uses expected credit loss provisioning. The US adopted its CECL model in 2020. Both recognized that delayed loss recognition threatens banking stability.
India delayed adoption partly because banks were already struggling with NPA cleanups in the mid-2010s. Imposing stricter provisioning then would have worsened an already dire situation. Now, with banks healthier, the RBI has set an April 2027 implementation date, giving banks 18 months to prepare.
What It Means
For customers, higher provisioning means safer banks less likely to collapse from unexpected losses. However, banks might become more cautious lenders or charge higher interest rates.
For investors, ECL changes bank assessment fundamentally. It levels the playing field, making Indian banks comparable to international peers on IFRS 9. Two banks with identical NPA ratios will now show more transparent provisioning differences based on actual risk, not just management discretion within loose rules.
The RBI’s move represents serious regulatory evolution. Open questions remain: Will banks embrace ECL honestly or game the models? How will investors react to initial profit hits from higher provisions?
One certainty stands: the rules are changing to make India’s banking system safer and more globally aligned.
