Millie-What’s wrong with bonds/treasury bills?
In a rising interest rate environment, they will be clobbered hard.
Let’s say that today you buy $100,000 of 10 year government bonds yielding $1,000 per year (1%).
Then inflation skyrockets and the Fed and the market drive the required interest on 10 year bond to 2%.
What is your $1,000 annual interest payment worth in a 2% world? $1,000 / 2% = $50,000.
You just lost half your money.
How do you feel about government “securities” now?
