Banking and financial services funds: doubling a bet you already hold

If you own any diversified Indian equity fund, you already have a large banking position. Financial services is the biggest sector weight in India's broad indices by a distance — often around a third of the index. So the first honest question about a banking fund is not whether the sector is attractive. It is whether you need more of what you already own heavily.

What the sector actually contains

"Banking and financial services" is broader than banks, and the sub-segments behave differently enough that lumping them together hides the risk:

• Private banks — the market's compounders, valued on growth in advances and deposit franchise quality.
• Public-sector banks — policy-exposed, historically cheap, capable of violent re-ratings in both directions.
• NBFCs — lend without a deposit franchise, so they live or die on access to wholesale funding. This is the segment where liquidity events happen.
• Insurance — a long-duration, entirely different business valued on embedded value rather than on loan growth.
• Asset managers, exchanges, brokers — capital-light, fee-driven, and correlated with market activity rather than with credit.

A "banking" fund holding mostly private banks and one holding mostly NBFCs and small-finance banks are different products with different failure modes.

How a lender actually makes and loses money

Two numbers drive almost everything, and they move on different clocks.

Net interest margin — what the bank earns on loans minus what it pays for deposits. Rate cycles move this. When rates rise, loans typically reprice faster than deposits and margins expand; when rates fall, the reverse. It is a spread business, and the spread is cyclical.

Credit cost — the provisions taken against loans that go bad. This is the one that matters, and it is the one that arrives late. Lending is the only business where you book the revenue immediately and discover the cost of the sale three years later.

That lag creates the sector's signature pattern: the reported numbers look best just before they look worst. A period of rapid loan growth produces excellent earnings, low apparent credit cost, and a rising stock — and the loans written during that period are the ones that default in the downturn. India's 2013–2018 corporate-lending cycle is the textbook case, and it ran long enough that the warnings were dismissed for years before they were right.

Leverage is the amplifier. A bank runs on borrowed money by design, so a small percentage of assets going bad can consume a large share of equity. This is why bank stocks fall so much harder than the index when credit worries start: the market is not marking down earnings, it is questioning the capital.

What to actually watch

If you own one of these funds, these are the numbers that matter more than the NAV:

• Gross and net NPAs, and the trend — the level matters less than the direction and the pace of new slippages.
• Provision coverage — how much has already been set aside against the bad loans recognised.
• Credit cost as a share of advances — the honest measure of what lending is costing this year.
• Capital adequacy — the buffer, and whether the bank will need to raise equity (which dilutes you).
• Deposit growth versus loan growth — a bank growing loans much faster than deposits is funding growth expensively, which is where NBFC-style fragility starts.
• CASA share — cheap current and savings deposits are the durable competitive advantage in Indian banking.

Does a dedicated fund earn its place?

Sometimes, with conditions.

The case for: financials are the most direct way to own India's credit growth, the sector is analytically deep enough for genuine research to add value, and a specialist manager may separate the good underwriters from the fast growers earlier than a generalist does.

The case against: you already own it. If the index is a third financials and your diversified funds track that, a 10% sector-fund sleeve takes your total exposure past 40% of equity — a concentration you would never choose deliberately. And when a credit cycle turns, everything in the sector falls together; the diversification inside the fund is much smaller than the number of holdings suggests.

If you do buy one:

1. Measure your total sector exposure first, across every fund you own — not the sleeve size. See how many funds you need.
2. Read the sub-segment mix. Private banks, PSU banks and NBFCs are three different bets.
3. Size it small and treat it as a satellite around a diversified core.
4. Judge it across a credit cycle, which is longer than a market cycle. Rolling returns over seven to ten years are the relevant window.

Pitfalls to avoid

• Ignoring the exposure you already have. This is the single most common error with this category, and it is entirely avoidable in ten minutes.
• Buying after a strong credit cycle. Peak earnings, minimum apparent credit cost, maximum enthusiasm — the same trap as any cyclical.
• Treating NBFCs as banks. They cannot take deposits and depend on wholesale funding staying available. When it stops, it stops suddenly.
• Reading a low P/B as cheap. For a lender, P/B is cheap for a reason — usually the market's view of the loan book.
• Assuming diversification within the fund helps. Thirty financial stocks in a credit downturn are thirty correlated positions.
• Confusing the sector's importance with its return. India needs credit growth. That is not the same as today's price being right.

Key takeaway

Financial services is already the largest sector in every diversified Indian equity portfolio, so a dedicated fund is a decision to double an existing concentration — measure your total exposure before you add to it. The sector's defining feature is that revenue is booked years before its cost is discovered, so the reported numbers look best at exactly the point in the credit cycle when the risk is highest, and leverage turns modest asset problems into large equity losses. Watch credit cost and slippage trends rather than the NAV, know whether you own private banks or NBFCs, and judge the fund across a credit cycle rather than a market one.
