The interplay between bond yields, the fed funds rate, and inflation can lead to weird situations. Right noe the Fed is having to lower rates because (a) job numbers are pretty bad and (b) the US debt is held in a surprising number of short term bonds and higher rates make the debt just rack up faster. They're also watching inflation continue to chug along higher than their 2% target though, a scenario they'd normally raise rates for.
I won't be surprised if we ultimately realize that, in the end, those in charge had way less control of the economy than they like to claim. I'm biased though, that's always been my view and it frustrates me that economics claims to be a field of science at all. It can be a very interesting and important historical analysis but it isn't predictive, and at the level of macroeconomics it can't realistically be isolated and tested.
