What is Gross NPA (GNPA)? Understanding Bad Loans & Bank Risk
The Answer
A Gross Non-Performing Asset (GNPA) Spike is a sudden increase in the percentage of a bank or NBFC's loan book classified as non-performing (where interest or principal has been unpaid for over 90 days). It is a critical signal of worsening credit quality and credit risk.
Why it Matters
Loans are assets for banks. A spike in GNPA means a higher portion of these assets are turning bad, reducing interest income and requiring loan write-offs that eat directly into profitability.

āA GNPA spike is a lagging price indicator but a leading solvency indicator. Track provisioning trends to see if the bank has built a cushion.ā
š How to Interpret
In Risk Context
In Flagium's framework, GNPA Spike is rated as a high-severity flag (F7, Weight: 15). It triggers if the Gross NPA ratio rises by >50 bps YoY, or shows sequential QoQ acceleration.
Deep Dive
Gross NPA Spike: Measuring Credit Quality Stress
In banking, loans extended to customers are assets, and deposits collected from customers are liabilities. When borrowers fail to pay their scheduled interest or principal payments for more than 90 days, the loan is classified as a Non-Performing Asset (NPA).
The Gross NPA Ratio Formula
The GNPA ratio measures the total value of bad loans relative to the bank's total advances:
A GNPA Spike represents a rapid degradation of the loan portfolio, indicating that:
- Underwriting standards have weakened (the bank has lent to weak borrowers).
- The macroeconomic environment is deteriorating (causing systemic defaults in sectors like retail or SMEs).
How Flagium Detects GNPA Spikes
Flagium monitors Gross NPA quarterly. It fires the F7 flag if the GNPA ratio spikes by YoY, rises for 2 consecutive quarters, or if QoQ rise accelerates.
RBI Asset Quality Review (AQR) and Divergence
In 2015, the Reserve Bank of India (RBI) launched the Asset Quality Review (AQR) to clean up banking balance sheets. This review forced banks to recognize highly stressed corporate loans as NPAs, leading to massive GNPA spikes across both public and private lenders.
Many banks had previously used "evergreening" (issuing new loans to pay off old ones) to hide defaults. When the AQR disallowed this practice, the gap between reported NPAs and regulatory reality was exposed as a "Divergence." Yes Bank's reported GNPA ratio spiked from 1.28% to 18.87% over six quarters as hidden defaults were brought onto the balance sheet, destroying shareholder value.
Diagnostic Checklist for Bank Audits
- Divergence in Growth Rates: If total advances grow at 10% while GNPA absolute value grows at 35%, asset quality is deteriorating rapidly.
- Slippage Ratio Trend: Slippages measure new loans turning bad during the quarter. A rising slippage ratio is a leading indicator of a future GNPA spike.
- Restructured Assets: Stressed loans that have been modified to delay defaults. If restructured loans exceed 2.0% of the loan book, they represent a hidden pool of future NPAs.
Detect risk early
Flagium tracks these signals across multiple quarters to help you avoid structurally weak companies before it reflects in price.
