How to analyze a bank (and why it's not measured like other companies)

Analyzing a bank with the same metrics as an industrial or tech company leads to wrong conclusions. A bank doesn't make or sell products: its business is money itself. That's why it's measured differently.

Debt isn't a risk: it's the business

In a normal company, lots of debt is a red flag. In a bank, it's the opposite: its model is to take in cheap money (customer deposits and other funding) and lend it out more expensively. That "debt" is its raw material. That's why metrics like net debt/EBITDA don't apply: a bank will always have a huge balance of "debt" because that is, literally, its product.

Free cash flow doesn't apply either

Free cash flow (operating cash minus investment in factories and equipment) is key in almost any company. But in a bank it means nothing: it has no factories, and its "cash" is loans and deposits constantly flowing in and out. Computing a bank's FCF gives meaningless figures.

What to actually look at in a bank

If debt and FCF don't help, what do you focus on? Four things:

  • Capital strength: how big a cushion the bank has to absorb losses. It's approximated by equity over total assets: the higher, the more resilient. Regulators use finer ratios (the well-known CET1), but the idea is the same: a well-capitalized bank withstands shocks; one with little capital is fragile.
  • Profitability (ROE): ROE is especially useful in banking. It measures how much profit the bank squeezes from its shareholders' money. A sustained ROE above 10-12% usually points to a bank that manages its capital well.
  • Bad loans: what share of loans isn't being repaid. Low, stable bad loans signal prudence; a spike, especially in a recession, is a bank's biggest risk.
  • Net interest margin: the gap between what it charges to lend and what it pays to raise money. It's the engine of its profit and rises or falls with interest rates.

How StockSemáforo handles it

Since net debt/EBITDA and free cash flow make no sense for a bank, our analysis doesn't use those two metrics for financial health. Instead we measure capital strength (equity over assets), the right way to judge a bank's solvency. We assess profitability mainly through ROE and margins. So when you analyze a bank like JPMorgan or Wells Fargo, the rating reflects what truly matters in banking and doesn't unfairly penalize "debt" that, in their case, is the business.

In short

For a bank: forget net debt/EBITDA and FCF, and look at capital, ROE, bad loans and the net interest margin. To see these indicators for any U.S.-listed bank, type its ticker into the analyzer, or start with the fundamental analysis guide.

Preguntas frecuentes

Why doesn't net debt/EBITDA work for a bank?

Because in a bank, debt isn't something to avoid: it's the raw material. It takes in money (deposits and funding) to lend it out at a higher rate. On top of that, banks don't report an interpretable 'EBITDA'. So net debt/EBITDA, so useful for a normal company, makes no sense here.

What's a good capital ratio for a bank?

As a reference, equity over assets of around 8-12% is healthy for a large bank (the regulatory minimum is about 5%). The higher it is, the bigger the cushion to absorb losses. Regulators use finer ratios (like CET1), but equity over assets is a good public approximation.

What are a bank's bad loans?

It's the share of loans whose borrowers have stopped paying (non-performing loans, or NPLs). Low, stable bad loans signal that the bank lends prudently; a fast-rising figure is a warning sign, especially in recessions.
