With the stock market showing tremendous signs of weakness in 2016, CDs let me rest easy. Roughly 10% of my diversified net worth is in CDs and other stable instruments currently yielding a blended rate of around 3.5% in 2H 2015. Even with rates so low, if I invest $250,000 at 2.3% I still earn $479 a month, which is a very nice chunk of guaranteed change for someone who no longer works for a living.
There are times when the 10-year yield might be yielding less than a similar duration CD. Look to invest in CDs to take advantage of such a spread. For example, the 10-year bond yield might yield 2.1%, while you can find 5-year CDs yielding 2.3%.
