Hi,
I don't think it's an act. I think he is a hyper guy, or if it is an act he has been doing it for so long he has become the guy.
As for his blow up it certainly is good for his profile. Boosts his image as a guy who cares. Personally I never took his hyper persona seriuosly, but I thought it was good for a laugh.
Also, he is right. The problem is so broad and systemic that the choices are:
1) lower interest rates and sharply devalue the dollar which will cause explosive inflation in gas prices, (and other commodities) in an election season;
2) leave rates alone to try to buy time, (which they did)
3) raise rates to save the dollar and create a brutal recession, perhaps a depression.
The Fed decided to stall for time and hope it blows over. It might work for now.
