Read Matt Levine’s column from today. https://www.bloomberg.com/opinion/articles/2023-03-10/startup-bank-had-a-startup-bank-run https://www.bloomberg.com/opinion/articles/2023-03-10/startu... The tech sector isn’t an issue in itself, it’s that (1) all their deposits all came in at once because it’s one sector, so there was a huge demand surge for deposit interest, leading to a supply shortfall of loans they could issue and hence kinda desperately parking the money somewhere, which ended up putting their risk balance off kilter (bonds with interest rate risk); (2) all of their depositors (aka creditors) talk to each other and listen to the same people, so bank runs happen really fast. Compare this to First Republic bank: demand for deposit interest does not surge dramatically because there is finite liquid cash needing to be deposited and so one sector getting a cash infusion comes at the cost of another. It smoothes out. Plus their customers don’t all talk to each other and behave like worst-case bank runners. All sectors are pretty highly correlated in the cash they have on hand and how they behave with it. It would be equally risky to be a bank that only deals with oil companies. Nevertheless it offers efficiencies for acquiring new customers and new business, so banks do it.
