I thought this Young and Thrifty blog post
said it well regarding those who think they can predict future interest rates:
It’s not really that hard to make a plausible case either way when talking about interest rates. Just use a lot of partial truths and spin in order to sound convincing.
This is why it's not a good idea to stop CD laddering due to what you think about future interest rates. One purpose of CD ladders is to help with both rising and falling interest rates. If rates rise, you slowly take advantage of higher rates as CDs on the ladder mature at regular periods. If rates fall or stay the same, you take advantage of the higher rates on the longer-term CDs.
