DBS, OCBC or UOB results: the five numbers that tell the real story
Bank earnings can look like alphabet soup. NIM, credit costs and CET1 become much easier when you know the question each number answers.
Begin with the engine: income
Split total income into net interest income and fee or other non-interest income. The first reflects the loan-and-deposit engine; the second can include wealth management, cards, trading and other activities. Growth is more convincing when it comes from several engines rather than one unusually favourable quarter.
NIM needs a companion number
Net interest margin measures the spread a bank earns on interest-bearing assets after funding costs. A higher NIM can help profit, but examine it alongside loan growth and deposits. A wider spread on a shrinking loan book, or growth funded by expensive deposits, tells a less comfortable story than the headline suggests.
Find out what went wrong with loans
Non-performing loan ratios show the stock of troubled loans; credit costs show the impairment charge flowing through the period. Compare both with earlier periods and read which industries or countries caused movement. A low number today is reassuring, but management’s overlays and forward guidance can reveal concerns that have not yet become defaults.
Costs reveal operating discipline
Banks invest heavily in people, technology and compliance, so compare expenses with income through the cost-to-income ratio. One quarter can be noisy because of bonuses or projects. The useful trend is whether income is growing faster than the cost base without the bank starving capabilities it will need later.
Capital closes the loop
The common equity tier 1 ratio is a key buffer against losses. Compare it with regulatory requirements, the bank’s target range and its plans for dividends, buybacks or growth. Strong capital is valuable, but it is not idle cash waiting automatically to be paid out. End with five lines: income mix, NIM and loans, asset quality, costs, and capital returns.
