This article is supposed to be on FDIC Insurance but it tends to wonder all over the place. for example, In the last three paragraphs of "The Purpose of FDIC Insurance" section, the author dives into RMDs and how they work. These three paragraphs discuss nothing about FDIC insurance. I'd remove them.
Next, in the "FDIC Insurance Limitations" section, the author discusses the risks of mutual funds, life insurance and annuities, the taxation of municipal bonds...nothing to do with FDIC insurance. The last paragraph speaks of protection of U.S Treasury Bonds because they are guaranteed by the federal government. That's good info, but much of this discussion is not on point.
Back to the "The Purpose of FDIC Insurance" section, fourth paragraph...it talks about FDIC insurance of retirement accounts such as IRAs and 401ks. This FDIC insurance is for deposits only: https://www.fdic.gov/resources/deposit-insurance/financial-products-insured. FDIC does not insure an IRA or 401k that's 100% invested in stocks. I'm pretty sure this linked article speaks of FDIC only covering Deposit Products like Money Markets. The fmg article is too vague and makes it sound like all retirement accounts have FDIC protection, when they don't.
So, looking for clarity and focus on the FDIC topic without all the tangential discussion on RMDs and how life insurance works.
Hope this helps...
