These are all variations of the possible reasons I was considering. It still could have been something weird and idiosyncratic I guess. Not sure whose going to by the bonds though if we are going to continue to run 2 trillion dollar deficits while cutting off trade. I would't touch a 30 year bond with a 10 foot poll.
The 10 year treasury bond rate hit 4.49% this morning, up from a low of 3.84% just last Friday .... but roughly unchanged from 4.40% merely two weeks ago .... it may just be volatility as bondholders try to figure out what to do amidst all this uncertainty. If the 10 year rate climbs over 5% I'll be concerned, but for now I just see it as volatility.
