I am trying to figure out the best way to protect ones brokerage account if banks start to fail. Essentially, brokerage accounts are insured 100k in cash and up to 500k in equities. How does one insure there cash if you have more than 100K and do not want hold equities? The only thing I have come up with as of right now is to put half in the SPY and the other half in the inverse SPX which is SH. It has come to my attention that inverse ETFs have a time decay. I was wondering how bad the time decay would be .....say if i held for a couple months. Would it be almost negligible. Hoping those who are more experienced with ETFs could help. Also, would holding ETFs count toward owning securities and be eligible for the equities insurance up to 500K ? If anyone has any other suggestions on account protection, it would be greatly appreciated. thanks.
