My bank account balance isn't going to drop if rates go up.  Treasuries are only risk free if you hold them to maturity.

You can get 6 month T-Bills that yield 2.133%, and it is correct that they are risk free if you only hold them to maturity. You can also hedge this by adding floating rate debt to your portfolio in small amounts, or capturing a spread.
