Looking at the FDIC website:
> The FDIC does NOT cover (even if purchased at an insured bank):
Stock investments
Bond investments
Mutual funds
Life insurance policies
Annuities
Municipal securities
Safe deposit boxes or their contents
U.S. Treasury bills, bonds or note
This article is about the bank's investments, if I read it correctly. Safe for a household does not mean safe for a company that lives on investment money.
