Return on Assets (ROA) for Banks

Why ROA, and not ROE, for banks

When you compare two Indian banks, the temptation is to look at Return on Equity. But banks are leverage machines — they borrow deposits and lend them out, so a thin sliver of equity can be inflated into a flashy ROE. Return on Assets strips the leverage out. It asks a simpler question: for every ₹100 of assets the bank controls, how many paise of profit did it actually earn?

That is why analysts and the RBI lean on ROA as the honest yardstick. A bank can juice ROE by borrowing more, but it cannot fake ROA without genuinely lending better, pricing better, or controlling costs better.

What "good" looks like in India

The rough rule of thumb in Indian banking is that an ROA around 1% is healthy, and consistently above that is strong. The gap between private and public sector banks shows up clearly here.

Well-run private lenders like HDFC Bank have historically held ROA in a tight, high band, and ICICI Bank's ROA climbed sharply over recent years as its asset quality improved. Public sector banks have spent years in the basement — many barely positive, dragged down by bad loans — though several like SBI and Bank of Baroda have clawed back to respectable territory as NPAs cleaned up.

The lesson: ROA is a slow-moving truth-teller. A bank that fixes its bad-loan problem watches its ROA climb, year after year.

How to use it as an investor

Don't read one year in isolation. Track the trend across four or five years, and always compare like with like — a small finance bank against another SFB, a large private bank against its peers, not against an NBFC.

My view: ROA is the single most useful starting number for any bank stock on the NSE or BSE. If a bank's ROA is rising while its provisions are falling, you are usually looking at a franchise that is genuinely improving — not one borrowing its way to glory. Pair it with the net interest margin and the gross NPA ratio, and you have a quick, brutal health check that no investor-relations slide can hide.
