Protecting SVB depositors, all of whom apparently have deposits greater than $250,000 (amount protected by FDIC) is... suboptimal. The moral hazard here is significant. You're not even protecting the average consumer here really, you're just bailing out people who made a wrong choice.
If you're going to keep hundreds of thousands of dollars in a bank, you should probably pay attention to who is holding your money.
The issue is that 250k is a trivial amount for even a small business with more than a couple dozen employees. With the average US annual salary of 70k, a business with 25 employees will already need half that amount each month to make payroll, and that's not including supplier expenses, utilities, rent, taxes, insurance, etc.
The depositor at the banks didn't make a "wrong choice" - they didn't open an investment accounts or brokerage accounts at SVB or engage in any speculative investments with the deposits, they simply deposited cash which is universally expected to be "safe" absent geopolitical and inflationary factors.
It's just simply not viable for every single business to hire their own accountants to audit the books of every bank they want to use and continuously monitor the bank's reserve ratios and capitalization or move hundreds of thousands of dollars every few months looking for the next "safer" bank. That's why the FDIC insurance fund is a necessary
evil tool to facilitate a robust and stable cash banking system by giving the people and businesses an implied guarantee of their money and so businesses can function efficiently
