What's an NPA (non-performing asset), and why would an interviewer ask you about it?

A Non-Performing Asset (NPA) is a loan or advance where the borrower hasn't paid interest or principal for more than 90 days. Once that 90-day mark passes, the bank can no longer count the loan as a performing, income-generating asset — it has to flag it, classify it, and set aside money against the risk that it may never get repaid.

That's the textbook definition. But to actually sound like you understand it in an interview, you need the layers underneath it.

How NPAs are classified

Banks don't just lump all bad loans together. Once an account crosses 90 days overdue, it moves through stages:

• Sub-standard asset — overdue for up to 12 months as an NPA
• Doubtful asset — remains an NPA for more than 12 months
• Loss asset — identified as a loss by the bank, auditors, or RBI inspection, where recovery is considered virtually impossible, though the full amount hasn't been written off yet

Each stage carries a different provisioning requirement — the percentage of the loan amount the bank must set aside from its own profits as a cushion against the loss.

Gross NPA vs Net NPA

This is where most candidates stumble. Gross NPA is the total value of all NPAs sitting on the bank's books, before any provisions. Net NPA is what's left after subtracting the provisions the bank has already made. Net NPA gives a truer picture of how exposed the bank actually is, because provisions are money the bank has already absorbed as a hit.

Why NPAs matter to a bank's health

An NPA doesn't just mean one customer stopped paying. It has a chain effect:

• Profitability drops — the bank has to provision against the loan instead of booking it as income
• Capital gets locked up — money that could've been lent out again is instead reserved against potential loss
• The NPA ratio becomes a red flag — regulators, investors, and rating agencies all watch Gross NPA % and Net NPA % as core indicators of how well a bank is managing credit risk

This is also tied closely to asset quality review, credit appraisal, and recovery mechanisms like SARFAESI and the Insolvency and Bankruptcy Code (IBC) — all things that come up once you're actually working in a bank's credit or recovery function.

Why interviewers ask this

It's rarely about testing whether you've memorized the RBI's definition. Interviewers ask about NPAs to check three things at once:

1. Do you understand how a bank actually makes money, and what threatens that — not just customer-facing service, but balance sheet health
2. Can you connect a textbook concept to a real business consequence — provisioning, profitability, capital adequacy
3. Are you prepared for the role you're applying for — if it's credit, operations, or collections, this isn't trivia, it's the job

A candidate who recites the 90-day rule and stops there sounds like they crammed a definition. A candidate who connects it to provisioning, the Gross/Net distinction, and why a rising NPA ratio worries a bank's management — that candidate sounds like they've actually read a balance sheet.

How to answer it well

Start with the definition in one sentence. Then immediately move to why it matters: provisioning, capital, and the NPA ratio as a health indicator. If you can, mention one real-world angle — a bank tightening its credit appraisal process, or recovery routes like SARFAESI — to show you're not just repeating a glossary entry.

Getting comfortable with concepts like this — the ones that sit right at the intersection of operations, credit, and regulation — is exactly what structured BFSI training is built around, rather than leaving you to piece it together from scattered YouTube videos before an interview.
