While John Maudlin is best at promoting... John Maudlin, I have read A Gary Shilling's books with some interest as he is one of the few writers that understands deflation.
Gary's long term take on the long bond yield at 3% is tough to stomach, but good reading, if for nothing else but 'just in case'. I do think that he adapts his world view to fit his long term target yield there, however. My technicals suggest that we are in a potential pivot zone for that long bond yield, and statistically, I think there is much more upside than downside (not that Gary couldn't be right). But, if you go and read the (rather long) bond thread in futures, you will also come to the conclusion that we are very much at a wait-and-see point in yields - once long bond yields drop convincingly below 4.40% I may have to join his camp (and lose my structural short in the 30 year from very opportune levels).
So, when you read the article, those graphs are of interest, but take it with a grain of salt and know where the writer is coming from.
And last I checked, while I certainly agree with the likelihood of lowering the fed fund rates again in the future, bad debt=increasing likelihood of losing your shirt while making a loan = tighter credit = higher rates charged on loans due to higher implied losses = higher long term rates, so in that respect I disagree with A. Gary.
You're tooo much of a permabear. You may be implicitly right, but I think you need to read more.
