If you would have purchased

If you would have purchased a 12 month CD 1 year ago vs. floating in a variable rate account (compounding w/ money market fund), you would have lost yield.

If you are convinced rates will continue to rise or remain stable, why would you lock your rate? – Especially with an inverted yield curve.
