The market expects Union Bank of India to carry on much as it has.

At today’s share price, buyers are assuming Union Bank of India earns about 13.1% a year on the money invested in it, from here on. Over the last ten years it actually earned about 15.2% a year. The two are close, so the share price does not need the business to improve or to stumble. It needs it to keep doing roughly what it already does.

  • How it is valued: Excess return — the correct lens for a bank.
  • What the price assumes: 13.1% return on equity, against 15.2% the model takes from its own record.
  • Ten-year record: Between FY2019 and FY2026, Union Bank of India's revenue went from ₹39,355 crore to ₹1,28,400 crore — it compounded at about 18% a year over 7 years.
  • Biggest swing factor: Credit costs. Main risk: Asset quality.

01Three banks in one

Union Bank of India, founded in Mumbai in 1919, is one of India's largest public-sector banks and is majority-owned by the Government of India. In April 2020 it merged with Andhra Bank and Corporation Bank, roughly doubling its size.

Like other state banks it went through heavy bad-loan provisions in the late 2010s; since the merger, lower credit costs have lifted profit.

02What the market is assuming

Work backwards from today's share price and you can see what buyers are quietly taking for granted. Here is the return on equity that price implies for Union Bank of India, next to what the model assumes from the company's own record.

The further apart these two numbers are, the bigger the bet a buyer at today's price is making.

03Union Bank of India's record, in plain numbers

Between FY2019 and FY2026, Union Bank of India's revenue went from ₹39,355 crore to ₹1,28,400 crore — it compounded at about 18% a year over 7 years. It reported a net loss in FY2019 and FY2020, and closed the period with net profit of ₹18,781 crore. In FY2026 it kept 14.6% of revenue as net profit — its best year in the period. Revenue slipped 1.2% in the latest year, well behind its own long-run pace. FY2022 is missing from the filed series used here, so that year is left out rather than estimated.

Reading the record. The FY2018 figure in the source data is out of line (a large profit in a year the bank was provisioning heavily), so it is left out of the calculations above. The FY2021 revenue jump comes from the merger.

04How Union Bank of India gets valued — and why

Excess return — the correct lens for a bank

A bank is not valued with a discounted cash flow. Deposits are its raw material and interest is operating income, so enterprise value means nothing here. It is valued on excess return instead — the profit it earns above the cost of the equity funding it.

05What decides Union Bank of India's value

Credit costs

Lower provisions drove the recovery.

Return on equity

Whether returns hold through the next cycle.

Deposit franchise

A wide branch network gives access to deposits.

Integration

Merger savings support efficiency.

06What could go wrong

  • Asset quality. A new credit downturn would hit profit.
  • Policy lending. Government priorities shape lending.
  • Capital. Growth may need fresh equity.
