For those with a CD ladder, it's academic. A rung matures, you grab the best deal you can find to fill the maturing rung. It's entirely different when you have a CD maturing which is "outside" your ladder. Then, you are faced with a quandary. In a rising-rate environment, what's the best "bang for your buck"?
In my IRA CD ladder, I've always been a fan of 5-yr CDs. In my after-tax CDs (which are not laddered), it gets complicated. Should I reach for the best yield and go long, or accept a more modest yield and a shorter term?
Background: My rule-of-thumb has always been roughly 20 - 25 bps in yield for each additional year in term. If I can make 1.05% on a garden-variety savings account (which I can and do), then I should search for a tier as follows: 1-yr CD 1.25%, 2-yr CD 1.5%, 3-yr CD 1.75%, 4-yr CD 2%, 5-yr CD 2.25%.
Analysis: For some bizarre reason, the math breaks down at the 2-yr CD level. I can obtain roughly 50 bps over the yield I might expect (2% versus 1.5%). However, when I move into the 5-yr CD range, I get closer to the yield noted above in "background".
Issue: Have I already answered my own question? Is not the 2-yr at 2% the "sweet-spot" these days, when factoring in term and yield? In a rising-rate environment, we don't want to get too far over our ski-tips, with respect to the term of a CD, but we want to make a respectable yield. Is the 2% 2-yr CD optimal?
