Banks who petition the Fed for FDIC insurance face much stricter reporting rules, capital reserve requirements, and limits on the riskiness investments they can make with client deposits from FINRA and the SEC. If you wanted, you could view the lack of FDIC insurance as a sign of a riskier institution overall, but like any other investment it might be worth it for the higher rate.

Just FYI, AFAIK, the standard 10 percent fractional reserve rate is no longer law after legislation post 08 crash bankers slipped through. So that old rule is very often not the case at a bank anymore.
