How Do Banks Make Money?

Original article

Without a doubt, the most important source of income is the net interest margin, and risk control that reduces bad debt risk is crucial.

You can check out the original article—it's pretty good. Overall, China has effectively shackled banks, reducing their profitability. The greater the responsibility a bank bears, the more constraints it faces, the less leverage it uses, the more cautious its style becomes, and the more it actively sacrifices its own profitability.

Business Models and Profitability

For consumer brands, only those with a competitive moat can convert brand strength into pricing power—and only with pricing power can they sustain high net profit margins. A brand doesn't guarantee high margins. However, another hallmark of a well-established brand is that it's harder to lose money; what worries most people often becomes an opportunity for them to buy in.

Can you Make Money Driving for Didi?

Based in Guangzhou, I asked a Didi driver about the numbers: car rental is 3,200/month, charging costs around 1,000, and after running 12+ hours a day, gross daily revenue is about 300 — roughly 4,000–5,000 per month. No social insurance, no benefits, and I’d pay rent and utilities out of pocket.

So it makes more sense to buy a car instead. Renting at over 3,000 is a bad deal. If I keep car payments under 3,000/month, I’m ahead — at least the car ends up being mine.
