Insurance Investments Bonds

I'm looking to invest in government bonds as an alternative to put my money in a bank that offers a very limited amount of protection ($ 250,000 limit for FDIC insurance). What obligations are the best to invest? Which bonds are the best yields and the greatest amount of protection? For example, if I put $ 5,000,000 in bonds, my money is protected until the bond has reached maturity? I was also told that the money will not be taxable if it is placed in government bonds, is this true? Any help from anyone would be greatly appreciated.

Thank you.

Yes, your money will be protected, but putting $ 5,000,000, inflation would eat that money. You can invest a portion of it in bonds and equity in income funds and get a much better return. Even an index fund.

It is safe to default. You get the key back when the treasury matures and interest payments are guaranteed. It is not tax exempt from federal taxes. But it is free from state taxes. You can buy directly from the treasury at www.treasurydirect.gov longer maturities normally have higher yields, more returns are subject to interest rate risk. You may want to consider I-bonds for inflation.
